For message related issues, the best tool to use is Spy++, which comes with Visual C++. I just tried it and I got a message number 0x0127 (unknown) for Windows+M. You may wanna look into it further.
One thing to note however, is that Windows+M works fine with a dialog-based app I have here. Is there something special about yours?

hello @all,
i need an instruction which waits until MATLAB will finish it's job.
earlier forum question:
hello @all,
i try to explain what i want / must do :
i have something like this:
i=0;<br />
while(i<5)<br />
{<br />
i++;<br />
}<br />
the only problem is the while loop. without these, the program part runs perfectly. however i need a while loop or something like that.
i think, the problem lie in the fact that the program sends the data to matlab and then directly in the code continues to go. possibly different processes run off parallel.
i think i must have something that waits so long, till matlab is ready with the diagram (i tried Sleep(1000) but it do not work).
maybe somebody know, if matlab has got a 'instruction' or if i can make something like a 'queue'.
thank you very much
happy

Hi!
I develop my own application using Visual C++. I need to get a directory where my application is launched.
I've found in MSDN two function: GetCurrentDirectory and GetModuleFileName. It seems that both methods are shown the right results (except for GetModuleFileName I need to make ReverseFind the first slash - but it's not hard to do). What method is the best ?
Yours sincerely,
Alex Bash

I strongly recommend you to use GetModuleFileName, this will give you the correct result. Be careful with GetCurrentDirectory, this will return the path your app is currently working in. E.g. if you create a file in "C:\Windows", this will be the current directory, regardless of whether your app is located there or not.

At the first state of application (I don't perform any creating of files) - do GetModuleFileName and GetCurrentDirectory show the same results ?
Yours sincerely,
Alex Bash

They can, but need not.
Example:
Create a shortcut to your program.
Modify the shortcut and specify a different directory for the working directory.
Run the program using the shortcut.
When you do this, those API routines will return two different things.

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

To be honest: I don't know. But I assume that if you call GetCurrentDirectory dierctly after startup it will return the path where your app is located. But I still think it is safer to use GetModuleFileName.
/edit: Tim is right

When I rotate a transparent bitmap, the transparent background color will be drawn around the bitmap (a one pixel halo). This doesn't happen when the rotation is horizontal or vertical. I am doing the following masking:
BitBlt( hScreenDC, r.left, r.top, curWidth, curHeight, hMemoryDC, 0, 0, SRCINVERT );
BitBlt( hScreenDC, r.left, r.top, curWidth, curHeight, hMaskDC, 0, 0, SRCAND );
BitBlt( hScreenDC, r.left, r.top, curWidth, curHeight, hMemoryDC, 0, 0, SRCINVERT );
At this point I have no clue as to why something like this would occur, because I have rotated the whole bitmap and saved it into the DC's. Has this happened to anyone before?
Thanks!

Sounds like your rotation code is causing your mask to degrade, so that the transparent colour where it is next to another colour is slightly changed. Have you verified that the pixels in question are EXACTLY the background colour, and not off by one or two ?

Can anyone tell me this?
I have a window that contains 4 to 5 property pages so the user can click on the tab on the top and change different things on each one. When the user hits OK, there are checks to validate some of the changes. If one of the validations fails, I want to go to the edit box that contains the information. But that edit box might not be on the property page the user is currently on. I have an error message saying what is invalid. But is there any way, after displaying the error message, to set the focus to the edit box on a different property page? I hope all of this is making sense.
In summary, I just want to be able to set focus on a control that might be on a different page than the one the user was on when he/she hit OK. Is there anyway to do this. Currently, it is setup using the Win32 SDK using PROPSHEETPAGE and PROPSHEETHEADER. No MFC used.

Try using PropSheet_SetCurSel. This function is simple to use, if you know the page handle or the index. For example, say your control is on the 3rd page out of 4 pages. The function would be:
PropSheet_SetCurSel(GetParent(hDialog), NULL, 2);
Then set the focus on your control. If you know the page and choose to use it, just replace NULL with the page handle...

Where and how do I make changes to how MFC opens a recent file when the user selects one from the menu?

Hi guys!
I'm a beginner and I just want to know how to change the background color of a MDI (without doc/view)app. There's a lot of exemples out there, but they are for dialog based app.
Also, I have some other problems. I'm not able to change the icon and title of my child windows.
I tried:
BOOL OpenGL_ContextMFC::PreCreateWindow(CREATESTRUCT& cs)
{
// TODO: Modify the Window class or styles here by modifying the CREATESTRUCT cs
if( !CMDIChildWnd::PreCreateWindow(cs) )
return FALSE;
cs.lpszName = "My child window name";//change my name here
cs.cx = 500;
cs.cy = 500;
cs.dwExStyle &= ~WS_EX_CLIENTEDGE;
cs.lpszClass = AfxRegisterWndClass(0);
return TRUE;
}
I can change the height and width of the windows but not the name.
Any ideas?
Thanks!

Hello everybody, i am trying to parse a simple CSV file (see a little file sample below) using the functions found in the book 'PROFESSIONAL MFC with VC++6' by M. Blaszczak, Wrox. I am working with VC7.
The functions work fine but unfortunately i can get only the first, say, N-1 values parsed instead of all the N wished ones.
for example in the sample below
i get parsed only:
label0 .. label5 as labels row (missing label6)
field0,f1,f2,f3,f4,f5 as first row of values (missing field f6)
0,10,20,30,40,50 as second row of values (missing 60)
and so on...
I mean only six values (with reference to the csv file sample), not all the seven values
any help/tip will be gratly appreciated!
Thanks in advance
