You are inserting the same pItemData for each node in the tree. Is that intentional?
johnnyXP wrote:
delete pItemData;
This is why nothing shows up.

_itemData* pItemData = new _itemData();
This statement is unnecessary in OnNMDblclkTreeTracks(). Memory was allocated in OnBnClickedOk().

Daim you are right! The data is not the same for each node. I do that just to simplify the question and the code.
Thanks a lot for your time.

Hey,
i build a nice custom control (::from CWnd). It works perfect on dialogs but can't print it.
I tried to create the control in my CView::OnPrint function --> Success.
But I never come to my OnPaint function. How can I print my control? Do I have to implement a special function with a parameter-handle to my printing DC?

If given a region (could be CRgn or even just an area described by a CRect), is there a way to check if that region only contains background color (nothing really drawn in there, i.e., no characters, dots, etc)? The simplist way I could think is looping through the region and getting each pixel via the CDC::GetPixel () method, and checking it against the background color. I am basically looking for a way to determine if something is drawn in a specific area.
I was hoping if there was a more "elegant" solution. Searches both here and on the 'Net as a whole seemed to turn up nothing regarding this.
Thanks

Look for:
StartDoc()
StartPage()
TextOut()
EndPage()
EndDoc() You'll likely need others, but these are a minimum.

I have written a code that has a window procedure for the main window. I trapped WM_CHAR message and wrote this code:
98 ......
99 case WM_CHAR:
100 MessageBox(hwnd, TEXT("KJHGKIF"), TEXT("KHTIUYT"), MB_OK);
101 return 0;
102 ......
(hwnd is a handle to the main window)
when run, I press a key and see a message box. at this time, window procedure is stopped at line 100. when I move messagebox, the client area of the main window is repainted. meaning that WM_PAINT is invoked. how can it possible? window procedure is running at two points?
|
|
|
|
|
Yes it is possible (and normal). messagebox has a dialog box loop ( something that reads message from the queue and dispatches them) which does not exit until you press one of the buttons. All modal dialog boxes have this. This allows other windows to be repainted when you move your dialog box (or to deal with timers or all sorts of events).
It looks like multi threading but it is not!
|
|
|
|

I guess the method is something like this: the function pushes all its data onto the stack, calls itself, after finish it pops the data back and continues its process. like the function for calculating n! (n! = n * (n - 1)!).
I guess messagebox sends a WM_PAINT message to its parent window using this method (and also when we call SendMessage function from the window procedure to send itself a message). is my guess true?
|
|
|
|
|
Absolutely true... it is absolutely like a recursive call

I have an MDI application created using VC++ 6.0. It has several dialog based executions. Now I want to seperate one such dialog based part and create a seperate new dialog based application.
Any suggestions, steps or points to be considered will be appreciated. Thank you in advance
