Well... let me give you more details. What I`m trying to do is replace the Windows clock with a window made by me. Now... I already did this. Partially. I can put my window there, I can do some resizing... but when the scrollbar is moved, bye bye blue sky : ). Even when the time changes I get some surprises (my window dissapears beneath the clock).
Anywayz, I think I have to install this hook ONLY on explorer.exe... because in the end, I`m only interested in the messages that the systray clock window receives. And then probably (now I`m just thinking without knowing if it's really like this) I can see when explorer.exe tells the clock to resize or repaint and tell my window to repaint before.
So two questions related to this... how can I find out the Thread ID of Explorer.exe so I can hook it? : ). And how can I block those messages of ever reaching the original clock window? That would be even better if it would be possible...
Thank you a lot for your help...

If you've got the window handle, use GetWindowThreadId()

Look at a WH_GETMESSAGE hook. You can prevent messages being sent to the window using the return value.

Well... I can't find out the Window Handle. I don't know what to search with FindWindowEx... I don't know a Window Class or a Window Caption for Explorer.
As for the WH_GETMESSAGE ... I didn't find any relevant documentation about it in MSDN when I looked at the SetWindowsHookEx.
Anyway, there are few things about which I am stil very confused. But I need to dig and read some documentation about all this before I ask useless questions. Can you tell me how to find that Hwnd for Explorer? Maybe give me a link or two about WH_GETMESSAGE? A link from your MSDN is also good as I could paste it in my MSDN. I got the MSDN that comes with .Net 2003.

Bulls'eye. I managed to find that class : ). As for the WH_GETMESSAGE, I would still appreciate some info related to it : >. Some links, maybe some MSDN link. You seem like a much more experienced programmer than me, specially in API. If it's not too much I would like to ask you some other things as well, after I finish reading some documentation about these issues. I am working as a programmer at a company and this eats up a lot of my time, but I still want to go through with this challange of mine. If you could shoot a short mail to axonnus at yahoo dot com I would be very greatful : ). Of course, I'm pretty reluctant myself at helping freshers but... I would really needs some help related to this... thanks a lot. Have a nice day : )

I output some text using DrawText. Now I want to figure out if a certain extra text will still fit the last line.
e.g. I for
|This is the first line and now the|<br />
|second____________________________|
I want to write
|This is the first line and now the|<br />
|second____________________More... |
- but if the "More" doesn't fit, I want to move it to the next line.
So I think need to figure out how many x pixels the last line of the original text occupies.
With DT_CALCRECT I can figure out the extent of the entire text, but not how much on the last line is occupied.
Any ideas?

You could call the method twice with DT_CALCRECT, one with the "More" and one without. If the height of the calculated rectangle changes, then you know that the "More" didn't fit on the line, so it was moved to the next line by DrawText().
Just a thought...

But it could work 
(I still have problems with the different font etc., but I guess that I can compensate for)

CDC::DrawText have a "nFormat" parameter , use DT_CALCRECT can figure out how much rect;
e.g
CRect rt(0, 0, 0, 0);
pDC->DrawText(szText, rt, DT_CALCRECT);

I have a modal dialog box created by a class(say class A). I want to close this dialog box from another class (say class B),which is not derived from class A .I think,the way how this should be done is to get a handle to the dialog box and close it, from the class B. Can you suggest me how I can accomplish this, since I dont have access to the dialog box class's object(class A 's object, i cant even pass it as i class A is unknown in class B) at the point where i want to close it (in class B).

if you know the name of dialog box , you can use FindWindow to find the HANDLE of WINDOW . and send message to dialog to close it.
e.g
CWnd * pWnd = FindWindow("Dialog","NAME") ;
if( NULL != pWnd->GetSafeHwnd() )
{
pWnd->SendMessage(WM_COMMAND,IDOK,0);
}

Have you looked up LNK2005 in MSDN? There is a fairly extensive explanation about the error there.

Hi!
I'm making a simple mapeditor in MFC for a game and I would like to add a new window where the user can see the map renderd in openGL.
So I'm simply looking for an article on how to create a new independent window in my MFC project. I've searched the site, but i haven't found anything. Can anyone help me find it?
Thanks!

I'm using this project for the basis of my learning. However, I'm having trouble incorporating the class into my project. I read about device contexts and such but I couldn't find a straightforward sequence of steps to change my app to accept the new routines. I'm looking for information on what type of code to add and where, not a simple copy and paste job, but something concise. For instance, adding "CDC *pDC;" to my app class, and to add "pDC = pFrame->GetWindowDC();" is what I'm looking for. I tried to read through the project demonstration mentioned above to pick out the information but there's too much to wade through. Can anyone help me out?

Hey Folks,
Newbie. I have many dialogs using buttons. The text fits great on my computer, but when I load the program to other computers the text is too big. I assume that this is font management but I don't really know how to control them. Please point me in the right direction.
Thanx.

you are try func "SetFont" to set font .
e.g
CDialog dlg;
CFont font;
font.CreateFont(...... );
dlg.SetFont(&font);
