If you can capture the mouse (see SetCapture) then all the mouse messages will be obtained to your window through OnLButtonDown, OnLButtonUp, OnMouseMove, etc.
If you cant use a mouse hook. You will get enough articles here in CP regarding this.

If you need to get the mouse messages without affecting its functionalities, you cant capture the mouse. That means if you capture the mouse then all the events will be towards you. You cant click anything in another window.

Actually I meant, "If you cant do a mouse capture, then use a mouse hook" And CP means CodeProject.

Hello ,
I have tried with SetCapture() function , it works but it gives message only at first time i click on the desktop (or client Area which i have created as window using WNDCLASSEX and CreateWIndow()) and then i click on the disktop that msg does not come or my procedure does not catch it.
I am using window procedure to catch the message.
Plz Reply me.
Thanks....

Hi,
Let me explain in detail.
I have taken my MFC application.. OK. In that I have taken one Simple Class with diff .cpp and .h files(RTMPDesk.cpp). In this class I want to check that whenever click on desktop or any other client area than that message should be catch by Application.So, for that i created on window using WNDCLASSEX structure and Createwindow() function.And I catch messages in Window Procedure which i have created in RTMPDesk.cpp file.
So , iget only one time whenever i click on that created window.I want to check it for every time wenever i click on window.Ok....
I hope everythig is clear.
Plz help me.
Ashish

OK... my doubt is that whether you want to block the mouse click to other windows when your application is running? Or only you need to get the event, but the other applications should get the click as usual?
For the first case, you can make a top level transparent window which covers the whole desktop, so all the mouse events will be sent to this transparent window.
For the second case, AFAIK, only mouse hooking is a solution.

To make an example would be large and, actually, your work.
Try it and post when you have problems, start looking in the codeproject and google, there are examples for sure.
Good luck

Hey,
I have a for loop iterating through a Vector. When my program hits certain conditions it needs to do get the value of an element and add one to it.
I tried this but it didn't work:
PrimeNumber(Iter + 1) += 1;
It has to be the next element in the vector and it has to increment that next elements value by one! I've tried declaring an Iterator and using similar code -> *Iter + 1 += 1; but that still doesn't work 
Does anyone have any ideas on how to modify the content of a vector? Thanks for all the help in advance I appreciate it!

Make sure you don't go beyond/access vector<>::end() when doing +1.

Hello,
How can I attach child window's caption to the frame window in the OnSize() Function?
Right when I maximize the child window it gets maximized without actually the caption getting merged with te frame window.
This is the code in the OnSize()
switch(nType)
{
case SIZE_MAXIMIZED :
{
CRect R;
GetParentFrame()->GetClientRect(R);
MoveWindow(R,true);
break;
}
}
Regards
Prithaa

It's already being done for you if you are using DocView architecture by MFC.

Hello,
Thanks.
No I am nt using Doc -View Architecture and the caption doesn't get merged with the frame window.
What should be done?

Take a look in BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs) . There is where I defined the captions for the "seconday views" on my project.

Hello,
Thanks for your reply.
I have the caption initially when the window is created but when I maximize the child window the caption does not appear alongwith the frame window .
What should be done?

When you maiximize a chil window, it loses its own caption, and share the main frame caption, another thing is to fit the child window to the whole client area of the parent, but maximizing... nothing to do.

The call stack when execution reaches WinMain is as follows..
WinMain(HINSTANCE__ * 0x00400000, HINSTANCE__ * 0x00000000, char * 0x00141f09, int 1) line 27
WinMainCRTStartup() line 330 + 54 bytes
KERNEL32! 7c816fd7() Press F10(I am using VC6) to see how execution starts in an MFC application. Step through the code. Don't forget there is a global CWinApp object too.
