Thanks! After couple of articles descibing this 'bug' I have successfuly tested this solufion:
Instead of using plain SetForegroundWindow()/SetFocus() I use this:
//Attach
AttachThreadInput(GetWindowThreadProcessId(::GetForegroundWindow(),NULL),GetCurrentThreadId(),TRUE);
//Do our stuff
SetForegroundWindow();
SetFocus(); //Just playing safe
//Detach the attached thread
AttachThreadInput(GetWindowThreadProcessId(::GetForegroundWindow(),NULL),GetCurrentThreadId(),FALSE);
...and it's working fine! (on winXP)

i need to draw a rgb histogram for an image file in vc++.
Where can i find a code for it?or where can i find guidance regarding algorithm.
|
|
|
|
|
allocate 3 integer arrays of 256 elements (one each for R, G, and B). initialize them all to 0.
foreach pixel in the image
{
RedArray[pixel.red_component]++
GreenArray[pixel.green_component]++
BlueArray[pixel.blue_component]++
}

Thanks, now how do i draw it on screen?
|
|
|
|
|
pick a rectangle on-screen, that's 256 pixels wide.
find the largest value in all your histograms, max_val
for each histogram, start at 0, go across the rect, drawing lines ((rect_height / max_val) * cur_histo_val) high.

Hi all,
Im looking at developing a program that simply keeps a log of which users have accessed a specific program, i.e. Program icon is clicked, then a log is updated with user details i.e. Who last used the program, IP address, User name etc etc.
Any ideas? Getting the user details shoud be faily easy..
Many Thanks
Karl

And you can't alter that program?
Then I'm out of luck.
Maybe you can have a service running that hooks the mouse and finds out if a mouseclick is going to an applicaltions icon, but...

Sorry. 
I found this so obvious, I didn'n think that he was missing this bit of information.

In tree control how do I set different color for each tree item text.
i.e.
Root
Item1 with one color
Item2 with another color
Sachin

Handle NM_CUSTOMDRAW and you can set the color on a per-item basis

Hi,
I am developing a application in which I need to draw the some text and graphics on the view. I can do this in OnPaint as well as in OnDraw. But when one should use OnPaing and when OnDraw()? What is difference between OnPaint and OnDraw?
Regards,
Hemant Kulkarni.

OnDraw() is ultimately called by OnPaint(), as you can find inside MFC sources:
void CView::OnPaint()
{
CPaintDC dc(this);
OnPrepareDC(&dc);
OnDraw(&dc);
}
There you can also see what happens inside OnPrepare().
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

In the structure of MFC,OnPaint is the member function of Cwnd,OnDraw is the
member function of CView

OnPaint() belongs to CWnd and handles the WM_PAINT message, while OnDraw() belongs to CView and is virtual.
