"Yes, but why do you want to?"
Thank you, sometimes it's like talking into space, devoid of logic and reason around here.

I have an MFC Dlg Application. Say the project is called Test.
Visual Studio creates a TestDlg.cpp and a Test.cpp among others.
I am finding that some initialization that i need to do in the Test.cpp involves me having to have access to a variable in the TestDlg.cpp.
I cannot do a static cast of the TestDlg.cpp can I?

Before calling the dialog's DoModal() method, you can access the dialog's public members.

"Test.cpp" is where your CTestApp implementation is.
"TestDlg.cpp" is where your main dialog window CTestDlg implementation is.
In "Test.cpp", there is the function CTestApp::InitInstance.
Inside this function body, you can see the variable
CTestDlg dlg;
dlg.DoModal();
So you can do initialization like this:
CTestDlg dlg;
dlg.InitMyMemberValues();
dlg.DoModal();

Is this the same way of thinking for a View application as opposed to a dlg based?

This is the C++ object-oriented way.

What i mean is in a dlg based app we have:
CTestDlg dlg;
dlg.DoModal();
in the initistance.
What is the equivalent for a Single or multiple document based application? In other words , the same original question,just applied to a single or multi0ple document based app instead of a dlg based?

After the view object has been created, you can access its public members.

not sure if it's really related to your problem, but have a look at this article[^] anyway...

I would add a CTestDlg member variable to CTestApp and change InitInstance to use that instead of one local to InitInstance.

I want to capture client area of a window.
I am using vc++ and vs2005.
|
|
|
|
|
Be prepared for long stakeout. The client areas only come out at certain hours during the night and tend to be sensitive to noise and light. It takes a lot of skill to capture them.
|
|
|
|
|
Nice joke, I am able to capture a window and also able to solve this image into a file but the problem is i can't print only the client area.
I have also use the flag PW_CLIENTAREA.
Please help to solve this
|

I assume you wanted to do this in MFC...
bool CaptureWindow(CWnd* pWnd, CBitmap* pBitmap)
{
CRect rc;
pWnd->GetClientRect( rc );
CClientDC dc(pWnd);
if ( pBitmap->CreateCompatibleBitmap(&dc, rc.Width(), rc.Height()))
{
CDC memdc;
memdc.CreateCompatibleDC( &dc );
CBitmap* pOldBitmap = (CBitmap*) memdc.SelectObject( pBitmap );
memdc.BitBlt(0, 0, rc.Width(), rc.Height(), &dc, 0, 0, SRCCOPY);
memdc.SelectObject( pOldBitmap );
memdc.DeleteDC();
return true;
}
return false;
}

is it possible to do this using printwindow?
|
|

|

I want to capture client area of a transparent layered window
|
|
|
|
|
I've never used that API (PrintWindow) (or WM_PRINTCLIENT message) but I would believe that should do the trick. Not sure about the layered window though.
God bless,

this is a console app. what it is supposed to do is list the info for notepad.exe and then inject the .dll into the notepad.exe executable space.
it seems to list the program info correctly, but the injection does not work. (verified with ollydbg, the .dll isn't present)
anyone can help would be appreciated.

i included the project file for visual studio 2008 c++ in the linked Projects.rar and also the Caliber.dll that gets injected. (this .dll doesn't do anything at all, it's just for testing the injection.)
www.steveandmike.com/backup/Projects.rar
You must have notepad.exe running to see anything. probably best to build the application and then run the build in a console window.
thanks for any help!
best,
Mike

Format your code so it's readable.
Steve
|
|
|
|

what do you mean format so it is readable? i don't understand-
also i posted the actual project file for download-
at any rate, not sure what you mean.
can you give me an example of what isn't readable in the code i posted?
thanks for replying-
best,
Mike

There is no indentation.
Steve
|
|
|
|

ok. i have never posted here before. i simply copied the text from the actual IDE and then pasted here and then pressed the code formatting button below. what could i have done differently?
also, what does that matter? it is formatted and indented very nicely with color coding and etc. in the project file which is downloadable from the link included.
i really could use some help here. hopefully arguing over indentation isn't the norm here? i apologize for posting inappropriately but i have no idea how to get it like you want it. could you at least look at the code itself or perhaps load the project file and see what i am talking about? i would appreciate it-
best,
Mike

I'll answer a question if it's easy for me to do so; normally I would not go to the trouble of downloading a project file.
