I would bet there's some code here on CodeProject to do that very thing. I can get the diloag to hide itself, but it shows up in the taskbar (not the system tray). The way I hid the dialog (dialog-based app) was to call MoveWindow in OnInitDialog() and position the window WAY off the visible desktop. The code is still running, but you just can't see the dialog.
Here's a link to a comment from someone on how to make a dialog-based app not put anything in the taskbar, too.
http://www.codetools.com/docview/notaskbaricon.asp?app=100&df=100&exp=0&forumid=77&fr=1&main=/docview/notaskbaricon.asp&select=1058#xx1058xx
Or if you want to minimize the app to the system tray, go here:
http://www.codetools.com/useritems/trayicons.asp
There's also a comment that points out other articles on CodeProject that (I suspect) discuss the same thing.

How is that? I just tried what I gave you up and the app exists in the
Task List!
Maybe you missed these lines. Probably deleted them as well with the DoModal() call!
Remember to have these lines existed in your code lines:
CwhateverDlg dlg;
m_pMainWnd = &dlg;
Coz the above 2 lines are the application object! 
Just don't call the DoModal() guy! As I said when your app goes into the tray as an icon, you must have a context menu (right click) and an item to reload/show it on the screen! Or the double click procedure!
Tyr again and it should work!
Good Luck!

Doesnt work, but : if i change return FALSE ; to return TRUE; the first thing i get is an debug assertion error, but NOW THE PROGRAM NAME IS VISIBLE IN THE TASK LIST
if i do return FALSE; the app immediately quits after starting.
Maybe , you could please send me an example project to andreas.kuehntopf@gmx.de
BTW : Im using Visual C++ 6.0 Professional

Yes the retrun should be set to TRUE not FALSE as you said.
Apart from that everything else should be OK!
Would you just post your InitInstance() lines here?
If not, just copmare your code lines and it should be like this exactly:
BOOL CwhateverApp::InitInstance()
{
AfxEnableControlContainer();
#ifdef _AFXDLL
Enable3dControls();
#else
Enable3dControlsStatic();
#endif
CwhateverDlg dlg;
m_pMainWnd = &dlg;
return TRUE;
}
Remove every thing else.

To hide a dialog, call ShowWindow(SW_HIDE), to show it, ShowWindow(SW_SHOW)
To make it hidden on startup, call ShowWindow(SW_HIDE) in OnInitDialog.

Hi Christian!
This won't work coz the app class is alraedy calling the DoModal() in the InitInstance() already. Try it!
Also try my suggestion of removing the DoModal() and return TRUE in the app IninInstance() and then call the DoModal() from anywhere ealse requiring the appearnce of the dialog, it will work.

No it wont work 
I did exacty what you said , but when trying to run i get a big bad ugly Debug Assertion Error.
The Error Message says :
Debug Assertion failed !
Program: C:\dialoghide\debug\dialoghide.exe
File: Afxwin2.inl
Line: 140
For information...[blablabla]
END RETRY IGNORE

Hmm, i did a debug, the error is created in the file /MFC/Winmain.cpp in line 49
nReturnCode = pThread->Run();
but i wonder what all this means

If you look, you'll see the error is caused by an assert that the window exists ( i.e. the window corresponding to the dialog in question. I have a program that runs in the task bar and I use the dialog as a splash screen, and hide it with a timer ( it's a dialog based app ), which is why I thought ShowWindow would work. It certainly works with a timer called after a second. I'm not sure of the way around this, but I'd suggest a Win32 program that creates the dialog manually.

If you're seriously unable to write a calculator then I would guess you're trying to get us to do your homework. In any case, there is an implimentation of a calculator in Stroustrup third ed.

I wish I could give you, but coz it is part of a book, it is copyrighted and cannot be distributed w/o permit.
However, the book is Jeff Prosise 2nd edt. Windows with MFC Programming, chapter 8 and has an MFC dialog based, fully featured calc app.
If you are MFC programmer, It is good to have that book, even as a reference if you are advanced.

Hi
Does anyone know how to use SetFocus to set the focus for a child window in a MDI application?
Thank you for your time!

Do you just want to make a particular MDI frame active? CFrameWnd::ActivateFrame() does this.

Hi
Thanks alot for your reply. I tried it with ActivateFrame(SW_RESTORE); however, it seems to open a new child window instead of activating that present one. Do you know why?
Thanks again!

When a line is drawn in Windows, the pixel located at the ending point is always excluded.
That means if you call
dc.MoveTo(x1, y1);
dc.LineTo(x2, y2);
the line will be drawn without pixel (x2, y2).
When I draw a lot of small lines it is very noticable. I could call
dc.SetPixel(x, y, RGB(0,0,0))
but that is bad solution, because SetPixel is inefficient and I must know the color of the current pen.
Does anybody know if there is a way to draw complete line in Windows by using some special type of pen?
Maybe it is possible to rewrite line drawing algorithm at lower level?

You could use the following as an alternative method
dc.MoveTo(x1,y1);
dc.LineTo(x2 + ((x2-x1 == 0 ? 0 : (x2 > x1 ? 1: -1), y2 + ((y2-y1 == 0 ? 0 : (y2 > y1 ? 1: -1));
If you are in a differnt metric other other than font (like english or inches) then you would have to adjust the 1 value to be the equivalent to the metric type.
The math works out correctly and the code should work in theory; I just haven't had the time to try it out yet. It should be quick and easy for you to check.

I looked around codeproject's shell article but could not find any sample on batch file deletion.
I am finding files of certain specific extension ie. *.bmp and then need to delete them by one delete button (batch deletion).
One more thing is that I have a message box and it pops up to let the user select two options:
1) Total Delete from HD.
2) Forward to the Recycle Bin only.
Code fragements, examples, hints are all much appreciated!
