I recommend the event mechanism rather than sending messages.

Do this in the RECEIVER in a separate thread if needed.

HANDLE hEvent = CreateEvent(0, 0, 0, "MYMESSAGE");
WaitForSingleObject(hEvent, INFINITE);

Do this in the SENDER

HANDLE hEvent = CreateEvent(0, 0, 0, "MYMESSAGE");
SetEvent(hEvent);

Thanks for your help Paresh.
I know, how to send and recieve user defined messages in VC++ MFC based applications i.e., Dialog based/Doc View based application.

My main problem is to recieve user defined message in Win32 console based application. Though sending messages is not a problem. Problem is only to recieve the same.

Thanks

Did you mean, your console base application is running and you want to communicate to that application ?

Are you looking for something like IPC ?

If Yes, Please refer more information on IPC at here[^].

Hi All,
Is there a way we can startup the GDI+ 1.1 version?
If so what changes are required to use GDI+ 1.1?

Thanx.

1/ How did you learn about GDI+ 1.1?
2/ Did you search on microsoft? They probably know a thing or two about it.

I typed "GDI+ 1.1" into their search box, and this was the following link:
http://www.microsoft.com/communities/newsgroups/en-us/default.aspx?dg=microsoft.public.platformsdk.gdi&tid=9fd5c32d-07c6-4777-833c-6b47e1273b95&cat=&lang=&cr=&sloc=&p=1[^]
To take a quote from it:
No, it is not redistributable per EULA of office 2003 and Windows Vista.

So, you'll need to be running on vista, or require users to by O2k3.

I have made a GDI+ 1.1 Library up in C#, it even includes full legacy emulation (albeit a bit slower than the using GPU like the GDI+ 1.1 does) for when the client machine is windows XP, you can find it here with full source:

If you are using Windows APIs to open the AVI file, there are 2 possibilities.
You can either use the FILE_FLAG_DELETE_ON_CLOSE flag with CreateFile, or use DeleteFile to delete the file after use. In both cases, the file has to be first closed using CloseHandle.

If you are using a third party conversion library, it will have some similar function to close the source file or delete it after close.

It's really bad. If you had not mentioned this one you could be spared. You know the reason why you are not able to delete it , but are you asking the same question again? No matter what delete function you use, DeleteFile, BombFile, NukeFile, nothing will work until you close() your file. Just close it after you are done with your conversion. There's no other reason why it cannot be deleted.

Can we invoke any event as a Mouse Left/Right button action?

THAQCD8-Apr-09 16:07

8-Apr-09 16:07

I would like to select Window objects (Start, File, Close, Minimize, Maximize ...) as a real mouse, however I don't have a real mouse, but I can use my capture coordinate to move the mouse as the following:

SetCapture();
SetCursorPos(pos_X, pos_Y);
ReleaseCapture();

By any chance, when my pointer (pos_X, pos_Y) pointing at a Window object, can I invoke any command, event to do as Left/Right-Click like the real Left/Right mouse buttons?

Many thanks for any help. D'Oh! | :doh:

Hello THAQCD,

You can use - SendInput()[^] to simulate mouse events.

That's because a[100] refers to the 101st item of a (which doesn't exist anyway). To refer to the array, just use a.

Just be aware that arrays in C/C++ do not carry any information regarding the size of the array - if you need to process variable size arrays, you need to specify the array size.

Function call syntax helps...this code (note - it's _tstof, not _ttof - MSDN is a little ambiguous here)

{
   CString a("11");
   const int i = _ttoi(a);
   const double d = _tstof(a);
   std::cout << i << std::endl;
   std::cout << d << std::endl;
}
{
   CString a("11.5");
   const int i = _ttoi(a);
   const double d = _tstof(a);
   std::cout << i << std::endl;
   std::cout << d << std::endl;
}

produces this
