Error 1:
---------------------------
Microsoft Outlook
---------------------------
Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client.
---------------------------
OK
---------------------------
When trying to send an email you get an error message "Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run MS Outlook and set it as the default mail client." RESOLUTION:
Install MS Outlook (not Outlook Express). Quit all mail-aware programs. This includes any MS Office programs and follow these steps to set Outlook as your default e-mail program:
Solution :
----------------
Start MS Internet Explorer version 5.0 or later.
On the "Tools" menu, click "Internet Options".
On the "Programs" tab, in the "E-mail" list, click to select "Microsoft Outlook". Do not click "Outlook Express".
Click "OK".
Error 2:
I developed the sample application with the MAPISendMail () fn in VC++.
MAPISendMail() fn succeeded But I got the mail in the Outlook's OutBox folder.But the mail is not sent to the specified email Id...
I enabled the "Forwarding and Pop" -> Enable POP access option from the
4.20 to 5.30 - I faced the above problem.
Set of Steps Taken :
1.So I set the status of the Firewall as "Allow All". Now also I got the problem that is message sent to the Outbox folder. So there is no problem with firewall.
2. I manually sent the mail from Outlook. It is also not working . It sends data to the Outbox folder. This is the cause of the problem. First set the mail settings properly in outlook Express.
I solved this problem By doing the following things:
1.By Enabling My Server Requires authentication
Moreover I have opened the Microsoft outlook and checks whether the MAPISendMail() fn works well …
MAPISendMail() fn failed with Outlook.
MAPISendMail() returns MAPI_E_FAILURE ( return code : 2) , if I opened the outlook.
So I opened the Outlook Express and tested the MAPISendMail() fn , it works well …
Tools ->accounts select the account name
Gmail Settings in Outlook Express:
Run the MAPI only when Outlook Express is Opened…

Directshow Things learnt from exp and thru newsgroup
Knowledge base :
1.what the IStreamBufferSink interface will do ?...
The IStreamBufferSink interface is exposed by the Stream Buffer Sink filter. Use this interface to lock the filter before capture and to create new recordings.
2.How to convert rgb24 to i420? Pls help me if you know. ?
RGB to YUV Conversion
Y = 0.299R + 0.587G + 0.114B
U = (B-Y)*0.565
V = (R-Y)*0.713
YUV to RGB Conversion
R = Y + 1.403V
G = Y - 0.344U - 0.714V
B = Y + 1.770U
3. I use directshow.net and pushfilter.
I connect pushfilter to videorenderer.
Same code works well when I use videoinfoheader. But if I chance it to
videoinfoheader2
(I need 16:9 flag for dv avi) filters does not connect. Fox. it connects to
smarttee but not to any renderer.
VideoInfoHeader2 format is not supported by the video Renderer.
we have to use Overlay Mixer for supporting VideoInfoHeader2 structure.
From Overlay Mixer onwards we have to connect it to the Video Renderer.
4. When I registered my mpeg decoder filter and use a third-party real-
time DV player software, the render windows becomes strange. The
decoded picture should be displayed limited in the fixed window, but
sometimes the picture becomes three the same picture as original, and
the center one lies the right position in the fixed window, the left
two arrange the left and the right.
what's wrong with my decode filter?
Decoder filter's Output image size is larger than the actual image size (output from the decoder)
So For the rest of the places, the directshow will copy more than one according to the window.
w can see the list of codecs installed in a system by doing following things :
1.Start ->Settings ->ControlPanel ->Sounds and Audio devices
2.Select hardware tab.
3.Select audio codecs and video codecs to see the list of codecs installed in a system

1.Use WriteAVI project, it supports more codecs...

1.what the IStreamBufferSink interface will do ?...
The IStreamBufferSink interface is exposed by the Stream Buffer Sink filter. Use this interface to lock the filter before capture and to create new recordings.
2.How to convert rgb24 to i420? Pls help me if you know. ?
RGB to YUV Conversion
Y = 0.299R + 0.587G + 0.114B
U = (B-Y)*0.565
V = (R-Y)*0.713
YUV to RGB Conversion
R = Y + 1.403V
G = Y - 0.344U - 0.714V
B = Y + 1.770U
3. I use directshow.net and pushfilter.
I connect pushfilter to videorenderer.
Same code works well when I use videoinfoheader. But if I chance it to
videoinfoheader2
(I need 16:9 flag for dv avi) filters does not connect. Fox. it connects to
smarttee but not to any renderer.
VideoInfoHeader2 format is not supported by the video Renderer.
we have to use Overlay Mixer for supporting VideoInfoHeader2 structure.
From Overlay Mixer onwards we have to connect it to the Video Renderer.
4. When I registered my mpeg decoder filter and use a third-party real-
time DV player software, the render windows becomes strange. The
decoded picture should be displayed limited in the fixed window, but
sometimes the picture becomes three the same picture as original, and
the center one lies the right position in the fixed window, the left
two arrange the left and the right.
what's wrong with my decode filter?
Decoder filter's Output image size is larger than the actual image size (output from the decoder)
So For the rest of the places, the directshow will copy more than one according to the window.
w can see the list of codecs installed in a system by doing following things :
1.Start ->Settings ->ControlPanel ->Sounds and Audio devices
2.Select hardware tab.
3.Select audio codecs and video codecs to see the list of codecs installed in a system

I got the Error like urs :
I did the following things :
1. open the Directshow baseclasses .dsw (which gives output as strmbasd.lib)file in an VC++6.0 and compiled it.
( Make sure whether the VC++ 6.0's compiled strmbasd.lib included in a directshow application)
2. Next I included this strmbasd.lib in Linker's Input option.
3. in Tools ->options->Include Files option,
Included the C:\DXSDK\Include directory in Tools ->options
after the inclusion of this directory also I got an error.
Solution :
I rearranged the directories order in an ascending order

4.Add the C:\DXSDK\Lib directory in Tools->options ->Library Files
5.Now compiling the filter works well.

Modify the Grabber filter to work with Sample Grabber
I modified the grabber Directshow filter in MSDN sample.
This grabber is used in our WMINTF application.
The modification is as follows :
typedef HRESULT (*SAMPLECALLBACK) (
IMediaSample * pSample,
REFERENCE_TIME * StartTime,
REFERENCE_TIME * StopTime,
BOOL TypeChanged);
the above code is changed as follows :
typedef HRESULT (*SAMPLECALLBACK) (
IMediaSample * pSample,
REFERENCE_TIME * StartTime,
REFERENCE_TIME * StopTime,
BOOL TypeChanged,
void* pInstanceData);
MIDL_INTERFACE("6B652FFF-11FE-4FCE-92AD-0266B5D7C78F")
IGrabberSample : public IUnknown
{
public:
virtual HRESULT STDMETHODCALLTYPE SetCallback(
SAMPLECALLBACK Callback) = 0;// this code is changed as follows :
virtual HRESULT STDMETHODCALLTYPE SetCallback(
SAMPLECALLBACK Callback,void* pInstanceData) = 0;
}
class CSampleGrabber: public IGrabberSample
{
public:
HRESULT STDMETHODCALLTYPE SetCallback(
SAMPLECALLBACK Callback) = 0;// this code is changed as follows :
HRESULT STDMETHODCALLTYPE SetCallback(
SAMPLECALLBACK Callback,void* pInstanceData) = 0;
private:
// Newly added code...
void* m_pInstanceData;
};
SetCallback(SAMPLECALLBACK Callback,void* pInstanceData)
{
m_Callback = Callback;
m_pInstanceData = pInstanceData; //Newly added code
}
within the Grabber filter,
m_Callback( ) fn is called as follows :
HRESULT hr = m_callback( pms, &StartTime, &StopTime, *pTypeChanged); //I modified this code as follows :
HRESULT hr = m_callback( pms, &StartTime, &StopTime, *pTypeChanged,m_pInstanceData);
Afterwards I compiled the Grabber filter.
and copied the following code (Client's)grabber.h as follows:The user class argument is used...
Client must aware of the interface IGrabberSample .
This is done thru the client's grabber.h file.
class CGraph;
typedef HRESULT (CGraph::*SAMPLECALLBACK) (
IMediaSample * pSample,
REFERENCE_TIME * StartTime,
REFERENCE_TIME * StopTime,
BOOL TypeChanged,
void *pInstanceData);
// We define the interface the app can use to program us
MIDL_INTERFACE("6B652FFF-11FE-4FCE-92AD-0266B5D7C78F")

GUID Error
Error while using GUIDs :
-------------------------------------
I defined the guids using DEFINE_GUID() macro
and static const GUID identifier as a GUID variable...
Both of them give me an error at the CLSID .
For Example I used the CLSID_GrabberSample.
DEFINE_GUID(CLSID_GrabberSample,
0x2fa4f053, 0x6d60, 0x4cb0, 0x95, 0x3, 0x8e, 0x89, 0x23, 0x4f, 0x3f, 0x73);
During the reference of CLSID_GrabberSample , I got the unresolved symbol linker error in CLSID_GrabberSample.
I changed the GUID as follows :
static const GUID CLSID_GrabberSample = {0x2F, 0xA4,0xF0,0x53,0x6D,0x60,0x4C,0xB0,0x95,0x3,0x8E,0x89,0x23,0x4F,0x3F,0x73};
-Once again I got an error too many initializers for static const GUID...
Solution :
I included the "initguid.h" header file afterwards it is working fine.

BDL VideoQuality Filter Seeking problem
check whether the seeking is working with BDL video Quality Filter ?
How I fixed the problem in back ward Seeking ?...
Solution steps :
1 I Read Media time(Current Position) for the samples and added it to the ArrayList ...
2. From the List, Set the Seeking Position
3. Play the Filter graph again...
4. Then the Video is running, then the problem lies with setting proper media time
5. I Identified this problem, I have allocated the time boxinglimit( 7.15 pm to 8.10 pm)
6.Previously I set the media time somewhat truncated media time obtained from the Track Bar % value...
(and then use the IVideoFrameStep interface with the video Quality client, else the BDL video quality Filter is a problem)

Video Softwares List
1.Windows Movie Maker
2.Avid Free DV

Video editing software is application software which handles the editing of video
sequences on a computer. It usually includes the ability to import and export video, cut
and paste sections of a video clip, and add special effects and transitions; and it
sometimes includes the ability to encode the video for creation of a DVD, Web video,
mobile phone video, or video podcast. Video editing software generally also allows for
some limited editing of the audio clips which accompany the video, or at least the ability
to sync the audio with the video.
Media100, Lightworks, Sony Vegas, Avid, Adobe Premiere, Ulead VideoStudio and
Apple's Final Cut Pro are pioneers in video editing software and have a great influence
on how films and TV programs are edited. These systems use custom hardware for
video processing.
Several other software programs can be classified in this category, including Microsoft's
Windows Movie Maker, iMovie, NERO 7 Ultra, GEAR Software's GEAR Video,
Pinnacle Systems' MediaSuite, muvee Technologies' muveeNow and autoProducer,
and Sherif.

Develop mws like filter
mws.RingBuffer.tlb

mws.Icf
mwssource.ax - MWS Source Filter
mws.exe
How to make the media player to support new URL type like
mws://localhost:8080/NNS100_H
Process of playing the Custom File Format in a windows media player :
Here the new protocol or own file format is specified in mws.reg.
They also specify the Source Filter for the MWS in a registry.
So that whenever the user enters the mWS URL the windows media player
creates the Source Filter instance and passes the URL to the specified source Filter.
It is just the process of playing our own format on windows media player.
mws.reg file is as follows :
REGEDIT4
[HKEY_CLASSES_ROOT\mws]
@="MWS : Media WAN Server Protocol"
"EditFlags"=hex:02,00,00,00
"URL Protocol"=""
"Source Filter"="{0641BDB6-FBB3-446a-AFC5-C49F64B276B3}"
[HKEY_CLASSES_ROOT\mws\DefaultIcon]

"EditFlags"=hex:01,00,00,00
[HKEY_CLASSES_ROOT\mws\Shell\open\command]
@="C:\\Program Files\\Windows Media Player\\wmplayer.exe %1"
we can define our own network protocol or file writer...
Custom File Formats :
If you have a custom mux or file-writer filter that supports your own file format, you can specify the CLSID as the first parameter of the SetOutputFileName method:
IBaseFilter *pMux = 0;
IFileSinkFilter *pSink = 0;
hr = pBuild->SetOutputFileName(&CLSID_MyCustomMuxFilter,
L"C:\\VidCap.avi", &pMux, &pSink);
For more information about this usage, see ICaptureGraphBuilder2::SetOutputFileName.

Registering a FOURCC Code
Registering codes with Microsoft prevents needless duplication of work and helps development of standards. To register a FOURCC code, send e-mail to mmreg@microsoft.com. Please include your name, title, company name, and phone and fax numbers.
Use this e-mail address to register the following:
• Manufacturer IDs. Manufacturer IDs are unique IDs used on device drivers to identify the vendor for the driver. The driver vendor is usually also the hardware vendor.
Example Manufacturer ID: MM_ACME
• Product IDs. Product IDs are used to identify which specific device from a manufacturer is being used. For example, Microsoft has written drivers for the MIDI mapper and the WAVE mapper. Each of these has the (same) Microsoft Manufacturer ID and a unique Product ID. Product IDs and Product Names are assigned by the manufacturer.
The names must be unique; using your company name followed by the product name is suggested. For example, if the Acme Company wanted to register the Super Audio card, which has a synthesizer, MIDI I/O ports, and waveform I/O, appropriate names would be:
MM_ACME_SASYNTH
MM_ACME_SAMIDIIN
MM_ACME_SAMIDIOUT
MM_ACME_SAWAVEIN
MM_ACME_SAWAVEOUT
• Installable Compressor ID. The Installable Compressor interface requires the driver to uniquely identify itself with a FOURCC. In the AVI file, this is stored in the stream header chunk element fccHandler. Please consult the Microsoft DirectShow SDK, available through MSDN Professional subscription, for more information.
The FOURCC should be used to identify state data belonging to the driver. All codecs should use the following convention for defining their state information structure:
typedef struct _stateinfo { FOURCC fcc; .... } STATEINFO;
Then, when the state info in a SET_STATE_INFO message is received, you should check the FOURCC to verify that it has state information for the driver.
FOURCC Data Formats :
Data formats for FOURCC include: RBG, YUV, and compressed formats. RGB describes the colors produced by emitting light, such as on a video monitor. YUV formats can be either packed or planar. In packed YUV formats, Y, U, and V samples are packed together in macropixels and stored in a single array. Planar formats store each component in a separate array and then fuse the three separate planes to create the final image.
Tables of formats are available at the following sites:
YUV formats - http://www.webartz.com/fourcc/indexyuv.htm
RGB formats - http://www.webartz.com/fourcc/indexrgb.htm

COM interface and .NET interoperability
VC++ COM interface in a DLL :
-------------------------------
interface IModuleConfig
{
HRESULT SetValue(
const GUID* pParamID, VARIANT* pValue);};
DLL component Id is
9C9A2859-C76B-4205-A52A-3ADBA54458B7.DLL component implements this interface...
C# code :
I created the instance for the DLL component as follows :
[
ComImport, Guid ("9C9A2859-C76B-4205-A52A-3ADBA54458B7")] public class DLLComponent{
}
This is like defining the CLSID in VC++...
How to create an instance for the specified Guid ?
Type t = typeof(DLLComponent);
DLLComponent dllComponent;
dllComponent = Activator.CreateInstance(t);
How to Query the interface from the DLL component Instance ?
IModuleConfig config = null;
config = dllComponent as IModuleConfig;
or
config = (IModuleConfig) dllComponent;
But we have to declare the IModuleConfig interface in the C# as follows ;
[
ComImport, System.Security.SuppressUnmanagedCodeSecurity , Guid("486F726E-4D43-49b9-8A0C-C22A2B0524E8" ), InterfaceType(ComInterfaceType .InterfaceIsIUnknown)] public interface IModuleConfig{
[PreserveSig] int SetValue([In , MarshalAs(UnmanagedType .LPStruct)]Guid guid, ref Object obj);}
Afterwards we can call the interface method using its object with dot operator...
IModuleConfig config = null;
config = dllComponent as IModuleConfig;
config.SetValue(guid, ref obj);
Now it is working well.
Wrong code:
==============
Previously I defined the C# interface as follows :
[
ComImport, System.Security.SuppressUnmanagedCodeSecurity , Guid("486F726E-4D43-49b9-8A0C-C22A2B0524E8" ), InterfaceType(ComInterfaceType .InterfaceIsIUnknown)] public interface IModuleConfig{
[PreserveSig] int SetValue([In , MarshalAs(UnmanagedType .LPStruct)]Guid guid,[In , MarshalAs(UnmanagedType .AsAny) ref Object obj);}
I got the exception as follows, we can't use the "UnmanagedType
.AsAny" ref types and Array with offset parameters.I thank verymuch to muthu pandi anna for helping me to solve this problem.
For VARIANT* we have to use the ref type.

C# 2.0 New features
C# 2.0 new features (.NET framework SDK):
1.Partial classes allow class implementation across more than one file. This permits breaking down very large classes, or is useful if some parts of a class are automatically generated.
2.Generics or parameterized types. This is a .NET 2.0 feature supported by C#. Unlike C++ templates, .NET parameterized types are instantiated at runtime rather than by the compiler; hence they can be cross-language whereas C++ templates cannot. They support some features not supported directly by C++ templates such as type constraints on generic parameters by use of interfaces. On the other hand, C# does not support non-type generic parameters. Unlike generics in Java, .NET generics use reification to make parameterized types first-class objects in the CLI Virtual Machine, which allows for optimizations and preservation of the type information.
3.Static classes that cannot be instantiated, and that only allow static members. This is similar to the concept of module in many procedural languages.
4.A new form of iterator that provides generator functionality, using a yield return construct similar to yield in Python.
// Method that takes an iterable input (possibly an array) and returns all even numbers.
public static IEnumerable GetEven(IEnumerable numbers)
{
foreach (int i in numbers)
{
if (i % 2 == 0) yield return i;
}
}
5.Anonymous delegates providing closure functionality.
public void Foo(object parameter)
{
// ...
ThreadPool.QueueUserWorkItem(delegate
{
// anonymous delegates have full access to local variables of the enclosing method
if (parameter == ...)
{
// ...
}
// ...
});
}
6.Covariance and contravariance for signatures of delegates
7. The accessibility of property accessors can be set independently. Example:
string status = string.Empty;
public string Status
{
get { return status; } // anyone can get value of this property,
protected set { status = value; } // but only derived classes can change it
}
8.Nullable value types (denoted by a question mark, e.g. int? i = null;) which add null to the set of allowed values for any value type. This provides improved interaction with SQL databases, which can have nullable columns of types corresponding to C# primitive types: an SQL INTEGER NULL column type directly translates to the C# int?.
int? i = null;
object o = i;
if (o == null) Console.WriteLine("Correct behaviour - you have a runtime version from September 2005 or later");
else Console.WriteLine("Incorrect behaviour - you are running a pre-release runtime (from before September)");
When copied into objects, the official release boxes values from Nullable instances, so null values and null references are considered equal.
9. Coalesce operator: (??) returns the first of its operands which is not null
object nullObj = null;
object obj = new Object();
return nullObj ?? obj; // returns obj
The primary use of this operator is to assign a nullable type to a non-nullable type with an easy syntax:
int? i = null;
int j = i ?? 0; // Unless i is null, initialize j to i. Else (if i is null), initialize j to 0.

MFC Slider Control Message Handling
I worked with horizontal slider control in MFC.
in order to receive the slider control messages,
we have to add the HSCROLL or VSCROLL message
I added the following message :
ON_WM_HSCROLL() added it within BEGIN_MESSAGE () macro.next I added the fn like
afx_msg void OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar) ;while using Slider control, the SCROLL message is posted...
There are two main notification codes are available.
That are
TB_THUMBTRACK
//Slider movement (the user dragged the slider)TB_THUMBPOSITION
//WM_LBUTTONUP following a TB_THUMBTRACK notification messagevoid MFCDlg::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
CSliderCtrl * pControl = (CSliderCtrl*) pScrollBar);
switch(nSBCode){
case TB_THUMBTRACK://Slider movement (the user dragged the slider){
break;}
case TB_THUMBPOSITION:{
//WM_LBUTTONUP following a TB_THUMBTRACK notification message //StopTimer(); break;}
}
}
