Hello,
I'm having problems with minimizing all windows within an MDI at the same time. I can loop through all open windows and minimize them one at a time (but that causes lots of delay with more than 5 windows, as they all go one after the other).
I can minimize the whole application with:
::SendMessage(pMainFrame->m_hWnd, WM_SYSCOMMAND, SC_MINIMIZE, 0);
or I can minimize individual active frames with:
::SendMessage(pMainFrame->GetActiveFrame()->m_hWnd, WM_SYSCOMMAND, SC_MINIMIZE, 0);
But how do I minimize them all at once?
Thanks for your help,
Dave

That's not a standard message but an application-specific thing. As far as I know, closing them one at a time is your only option.
Just for grins, what would happen if you posted the message instead:
::PostMessage(pMainFrame->GetActiveFrame()->m_hWnd, WM_SYSCOMMAND, SC_MINIMIZE, 0); or
pMainFrame->GetActiveFrame()->PostMessage(WM_SYSCOMMAND, SC_MINIMIZE, 0);

Both just minimize the active frame (window), and not all frames.
I thought there would be something more standard(MFC) I could just send to the mainFrame which handles it all, similar to the way MFC handles tiling or cascading windows.

Didn't you put it in a loop?

Sorry, I may not have been clear enough,
When minimizing a window, it shows the animation of the window title bar being minimized to the bottom.
When looping through all windows to minimize, the delay of having to watch each window individually be minimized becomes significant with many windows open.
I was wondering if there was something which would minimize all windows at once, without having to sit through each window displaying its "minimization animation".
I appreciate your help so far!

No, you were perfectly clear. It's just that you said in the initial post, "I can loop through all open windows and minimize them one at a time" but in your last post you said, "Both just minimize the active frame (window), and not all frames." I assumed you removed the loop in the latter post, hence my confusion.
My suggestion to post the message instead of sending it was not meant to solve the problem but rather to minimize the perception of a delay.
If you had an example of an application that minimizes all open frames at once, you might could spy on it and see what messages, if any, are being used.

Found a solution with using
ShowWindow(SW_HIDE) first and then ShowWindow(SW_MINIMIZE),
This way XP doesn't show it's "minimizing animation" while minimizing, and it speeds everything up significantly!
Thanks for all of your help!!

I am writing a c++ code for converting bmp file into jpeg....
The algorithm i have followed is:
1)Convert RGB color space to Y,Cb,Cr..
2)Down sample Cb and Cr by 2..that means for each square block of 2*2 there is 4 different Y
value but 1 Cb and 1 Cr value..
3)Apply DCT to data units of each 8*8 pixels...
4)Then apply quantization on DCT coefficient by using standard quantization table of Cb and Cr.
5)Do zigzag ordering.
6)Encode the DC and AC coefficient separately using huffman encoding.
7)Write proper header and write huffman encoded value to the file...
By doing all this things correctly(cross checked for various imaged and values) I am still not getting
the jpeg image correctly displayed.
Then i made a small 8*8 24 bit(color depth) bmp file completly filled with color value R=10 B=10
and G=100...all 64 pixels are of same color..
The data that i m getting at every step is as follows...
Bmp Image Header:
size of header 40
width 8
height 8
no of planes 1
no of bits per pixel 24
image size 194
x resolution pixel per meter 2834
y resolution pixel per meter 2834
no of colors 0
no of imp colors 0
The Y Cb Cr conversion of (R,B,G)=(10,10,100) is (62,-29,-37)
so lets consider Y component first..
The DCT coefficient for Y component is :
495 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
After Quantization, the zig zag ordering of single data unit that i m getting is this, for Y component.
30 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0
Now the huffman coding of above zig zag order array is :
Y dc coding: 00111110
Y ac coding: 1010 (for ac huffman table(luminance Y) EOB value is 1010)
Similary huffman coding of Cb and Cr components is as follows:
cb dc coding: 11000010
cb ac coding: 01 (for ac huffman table(chrominance Cb,Cr) EOB value is 01)
cr dc coding: 110101110
cr ac coding: 01
Final Huffman code that i get is:
001111101010110000100111010111001 Length 33
so to make it divisible by 8 padding of 1 is done.
0011111010101100001001110101110011111111 Length 40.
Here each single 0 or 1 is actually a bit that needs to be stored as it is in the jpeg file but since we
cant write bit by bit into file, a total of 8 bit is taken and converted into a integer value in base 10
and stored that into a character which now takes 1 byte.
So this is all procedure and some specific data that i have shown here...but still i m not getting my
image shown correctly..
can somebody help me out on this!!!!!!!!!

You don't need code.
Use Win32 Shell api (1 line of code)

I have a listview within an MDI child window. There is another child window with tree control also in the MDI application.
Steps to replicate the problem:
First I open the child window with tree control, leave it as it is in non-maximized state.
Then I open the second child window which has the list view.
Maximize the child window which has listview.
Close the listview from maximized state.
Application crashes.
I have cornered it to a MoveWindow() call, but could not go any further, is this a known problem with listview, is there any specfic tweaking that needs to be done? It causes the crash irrespective of data filled in the listview!
Environment:
OS- XP SP3
Pure Win32 application
No MFC is used
This is my call to create the listview:
CreateWindowEx(<br />
WS_EX_CLIENTEDGE,<br />
WC_LISTVIEW,<br />
"",
WS_CHILD | WS_VISIBLE | LVS_REPORT,<br />
0, <br />
0, <br />
rect.right,
rect.bottom,
m_hwndParent,<br />
NULL,<br />
(HINSTANCE) GetWindowLong (m_hwndParent, GWL_HINSTANCE),<br />
NULL);

Where is the MoveWindow called?
On which window is MoveWindow called?

Hi Superman,
Thanks very much for your reply.
Sorry for missing out that detail. MoveWindow() is called on WM_SIZE of child window in winproc of the child window which has the list view in it.
case WM_SIZE:
RECT rect;
GetClientRect(hWnd, &rect);
MoveWindow(m_hwndListView,
0,
0,
rect.right,
rect.bottom,
true);
break;
|
|
|
|
|
I'm guessing the crash occurs because MoveWindow is called on the list view after it is destroyed.
Try putting an IsWindow check over the MoveWindow.
if (IsWindow(m_hwndListView))
{
MoveWindow(m_hwndListView,
0,
0,
rect.right,
rect.bottom,
true);
}

Thanks very much for your reply.
IsWindow() did not help.
Crash occurs only under following condition:
Child window containing tree control is opened and kept in non-maximized state
Then, child window containing the list is maximized and then this closed. 
Anything else that you could think of?
|
|
|
|
|
You could try to use MoveWindow only when the wParam parameter of WM_SIZE is SIZE_RESTORED.

That also does not help

Thanks for your time and help superman.
Tried IsZoomed(hWnd) to do some conditional operation when closing in maximized state, but that also did not help.
Problem was that an allocated object was being deleted in WM_CLOSE. When this was moved to WM_DESTROY the crash is solved. Still not sure why this was causing the crash only when in maximized state!!  Will look into this at a later time.

Okay first, I have an executable the loads several DLLs. One of these DLLs needs to create a window and set an openGL context. A second DLL, which gets placed in its own thread executes functions on the first DLL. The initial problem I had was that the window was being created upon loading of the first DLL, and when the second DLL called functions on it from it's own thread, the openGL context would not be valid. I fixed this by making sure the window was created by the second DLLs worker thread that calls all of its functions.
So now, I can verify that all of my openGL calls are not failing, the problem though is that nothing is happening in the window itself. Right after the window is created it appears to hang. The cursor changes over it and it is no longer selectable. I can verify that the windows message proc is being called correctly and it does get to WM_CREATE. I can also verify that the program itself is not hanging as the calls are still being made.
The only thing I can think of as the problem is that when the window is created it is launching it's own additional thread, and I am subsequently trying to make my GL calls within the wrong thread. First, does this sound like the problem, and if it is, is there a way to make the window launch within the same thread that created it? I have made sure that the HINSTANCE that is passed into CreateWindowEx is that of the DLL.
I hope this makes sense as it is a little long winded. Any help is appreciated.
Thanks,
Dustin
