What I want achieve is to show a combo in a menu box.
but creating a combox requires it to be created as child window of some other window. But since Menu is not derived from cwnd so we cant make a menu a parent of a combo box. I hope I am clear till this point.
What i am trying to do is not something very new. because in visual studio.net 2003 when you resize tool bars the combo boxes can now appear in the pop up menu that appears when you click the >> (chevron).
What I was trying to suggest was since we cant use the CMenu class now ,we should consider using a dialog box. This dialog log box will appear where the menu appears now when we click the >> button on a tool whose all buttons are not visible.
The dialog will act as a menu and we will make it act like as menu i.e. hightlighting and unhighlighting items when mouse moves over it and destroy it when it loses focus.
I hope I make some sense this time.
if anything is still obscure please ask

I'm having a small problem with my test program.
I have a Dialogbased program that has a bunch of buttons.
When I click on one of them, another Dialog appears. This new Dialog has only one button, called
"Continue".
Here's where my problem starts. This new dialog that appears should after a couple of seconds
activate another Dialog. This is done by a timer or Sleep function. The thing is that I manage
to get the third Dialog to appear automatically but I found that the Second Dialog with the button
"Continue" didn't show the button. It's like the Dialog is drawn but not the button.
Hope you understand my problem.
Is there any event that is sent afte the whole Dialog is painted, including the button or other controls?
I've tryed, WM_PAINT, WM_ACTIVATE, WM_SHOWWINDOW.
Please help!

Is your third Dialog is Model or ModelLess i.e. is it created with CDialog::DoModal [Model] or CDialog::Create and CDialog::ShowWindow [Modelless].....

My thir Dialog is ModelLess.
Hope you have an answer to my problem.

Are you able to move your second dialog (in your terms, new Dialog with one continue button)

I have the structrue
[code]
struct Card{
char szFileName[MAX_PATH];
BYTE *lpImage;
Cards CardType;
};[/code]
an array of this structure will store 52 images representing different cards.
at the begining of my program i need to load all the images, and this is my effort for loading an image:
[code]
HBITMAP hbm = LoadImage(0, (LPCTSTR)"img.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_DEFAULTSIZE);[/code]
hbm is of type HBITMAP, so how can i get it into the structure where theimage type is of BYTE?
cheers

in your structure, why don't you just replace BYTE* by HBITMAP* ?

someone created that structure for me. later on, each image will be passed into memcmp (memory compare), along with a gui bitmap, to see whether the bitmap exists.
will this still work with HBITMAP?

I have some problems handling two print buffers of the printer's native resolution (720 dpi).
I can do one m_hBitmap=CreateCompatibleBitmap(pDC->m_hDC,5784,7938), but the second buffer returns me a NULL handle...
How can I increase the heap memory buffer ? The GDI object's memory seems very thigh. Can the HeapCreate function solve the issue ? Just a quick note, the PC features 1.5 GB of RAM, and currently only 300 MB is used. So it's not a memory problem...

hi!
ive got a problem developing an avi source filter!
the problem is that i need to read the file from disk while the file is playing in directshow! the other way is the example that shows directshow in its sample file source that comes with the sdk, but it is too slow, because it reads the full avi file in ram in the load function (from the ifilesourcefilter interface) before getting connected to the avi splitter and so on it wastes too much time! ive read that it is possible not to read the whole file and get connected succesfully to the avi splitter faking the contents of the memory buffer and reading from the file only the riff header, the avimainheader structure and the idx1 structure, but i dont know if its really true!if you please wonna confirm me the parts of the file and the structures to do it that are needed to make the avi splitter get connected i will apreciate it a lot, cause im getting frustrated with this and it doesnt go on!
thanks a lot!

how do we copy data from a buffer to a structure
|
|
|
|
|
you can use bitwise operators (>>, &, |, <<) to copy certain bytes from a buffer to the corresponding field in the structure.
Er zit een korstje op mijn aars.
|
|
|
|
|
Or memcpy(&struct, buffer, sizeof(struct));
|
|
|
|
|
That's a solution but you'll need to be sure that the data in the buffer has the same format as your structure. What I mean is that in your structure, the members will be aligned on a 8 bytes boundary (but you can change that). So, if it is not the case in your buffer, you will have some problems.
|
|
|
|
|
Alignment can be adjusted and by default uses natual alignment up to 8 byte PODs. VC doesn't use 8 byte alignment.

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

Yes, that's what I said  .

 Err, pretty sure that it does. I had a bug two years ago because of that (loading data from a file and memcpy it to a struct) and I spent a lot of time to solve it. And it was because of the member struct alignement that was to 8 by default.

actually the thing isthat we have stored data in a buffer.....now we declared an aaray of a structure to copy that data.abb i dont know that how do we specify no of bytes using bitwize operator.
|
|
|
|
|
you cannot copy a whole group of varialbes into a structure, except at its initialization.
the rest of the time, you'll have to point each member of the structure to affect it...
this is because generally, the members of a structure may be by side, but not necessarily...

Try being more specific. How is the buffer declared? What's its content? In what format? How is the structure declared?
Withouth such details, the answer can only be as vague as your question:
Q: how do we copy data from a buffer to a structure?
A: you extract pieces of data from the buffer and put them into the appropriate fields of the structure.
