I made an app to save MSN webcam conversations and it works quite well. All it does is saving the DC of the MSN windows, but i know there must be a better, lowlevel sollution for this.
What approach should i take for writing an app that finds the Directx (MSN uses directx right?) surface and let me copy the data.

I need to launch a windows app. @ particular co-ordinates on my extended windows desktop, from within a MFC Dialog. I can launch the app. fine, but dont know how to launch it at a particular position.
I also know that if I position the app to the appropriate position and close it,it will come up in the same position the next time its launched, but thats not really the way I want to do it.
Any one has a clue?

Unfortunately, I am using ShellExecute() to launch the process, did that because we wanted for the app. to come up in its default program. i.e if its a word doc, MS word will launch it. If its a pdf adobe acrobat will launch it.
and unfortunately ShellExecute() doesn't let you pass position parameters.
Any other ideas?

Determine the files associated executable by looking in the registry then use CreateProcess to launch the executable and the file thus allowing you to use the position control available with CreateProcess().

Hi,
My appication shows an error while building,
LNK1168 - fatal error LNK1168: cannot open Debug/MYPROG.exe for writing
I have to restart to the machine everytime this happens.
Is there anyway to get around this problem?
Thanks,
Deepak Samuel.

It sounds like the EXE is running (i.e., did not shut down properly), thus cannot be overwritten.

Yeah...
This can happen if the message loop for the program is defective or the quit message isn't being posted. The window closes, but the application still sits around running.

I'm going to patent thought. I have yet to see any prior art.

Hi
I have a problem with a program i have distributed.
On some computers, there is an error message show: 'An invalid page fault in MFC42.DLL'
I have put my version of 'MFC42.DLL' on his computer in windows system directory, but problem remains.
Anyone any ideas?
Greetings

First of all why do u need to distribute MFC42.DLL?? ur not supposed to do that....
Just build ur application with Option MFC Statically Linked instead of Shared Dll.... ok?? then u need not bother abt whether the target does contain which DLL...
hope this works for u....
gud luck

Actually, you can. You may not distribute MFC42D.DLL, but that's a whole other issue.
What I would do is to get hold of VCREDIST.EXE from microsoft.com, and install that on the client machine instead.

I need to show a succession of full screen modal dialog boxes. And I would like to avoid the flickering between them...
My code looks somehow like this (in its very simplified version)
<br />
while ( isContinue )<br />
{<br />
CMyDialog dlgDialog;<br />
if ( dlgDialog.DoModal() ==IDCANCEL)<br />
isContinue = false;<br />
}<br />
Any ideas? Thanks!

In this scenario, there is no way to avoid the flickering because the dialog boxes are being created and destroyed each iteration of the loop. Explain a bit further what you are after and we might can come up with a better design.

I understand that the dialog gets destroyed and that triggers the flickering.
But I have tried something like this
<br />
CMyDialog * pdlgOld = NULL;<br />
while ( isContinue )<br />
{<br />
CMyDialog * pdlgDialog=new CMyDialog;<br />
if ( pdlgDialog->DoModal() ==IDCANCEL)<br />
isContinue = false;<br />
if ( pdlgOld != NULL )<br />
pdlgOld->DestroyWindow();<br />
pdlgOld = pdlgDialog;<br />
}<br />
if ( pdlgOld != NULL )<br />
pdlgOld->DestroyWindow();<br />
and overriden CMyDialog::EndDialog so it would return the value (by calling EndModalLoop) but not actually call ::EndDialog
But that does not seem to work!

Modal dialogs are not designed to be operated in such a fashion. What is the net result you are after?

I want to show dialog boxes one after the other to enter data (with a back and a next button) and I would like to avoid the flickering

Then use a CPropertySheet object in wizard mode.

This would be indeed the orthodox way, but the interface is a bit more complicated... I also need other buttons and the user can define where they will appear and how... that's why I need the dialog boxes!
Sorry to waste your time with my weird interface needs!

Since each page on a propertysheet is derived from CDialog, you can design them as necessary, both at design time and at runtime.

Hiya,
I'm trying to find a DirectShow H263 encoder/decoder pair that works with frame sizes other than 176x 144, especialy as the camera I'm using doesn't output in this size (a slight issue  ).
If anyone knows of one, I'd be grateful to know of it!! (Especiall 640 x 480)
Many Thanks
Loz
