1. MFC dialog app is created
2. 2nd modeless dialog is created with extended style WS_EX_APPWINDOW, it's then shown and updated. The parent is set to null or desktop with SetParent(NULL) or SetParent(GetDesktopWindow())
3. Main dialog window is minimized, and as it is, the taskbar space for the non-modal disappears and the non-modal dialog is also minimized
4. NO, i repeat NO messages at all are sent to the non-modal dialog such as you would expect (ex. WM_SIZE message).
My Question is simple, what the heck is going on? How does one stop MFC from stealing the non-modal dialog's messages and reducing it automatically and removing it's taskbar space?
So far no one has been able to answer this

Hi,
I have a MFC application that contains a recursive function. After going in approx 4500 - 4900 levels deep the application crashes without an error. It just disappears from the screen. I am assuming that the recursion is going so deep that it is killing the stack.
Is there a way to check for this and return before the stack overflows?
Here is my code.
void CMyAppDlg::DoWork(int i)
{
if(i == 4900)
return;
DoWork(i+1);
}
void CMyAppDlg::OnButton1(int i)
{
AfxMessageBox("Starting work!");
DoWork(0);
AfxMessageBox("Done working!");
}
I can probably implement my method without recursion (its a tree parse) but I'd like to know if there is a solution to this. Any help will be appreciated.
Cheers,
Rahul

 Don't do that!
I do not know of any way to check the stack, but I am not supprised your code would overflow it. You realy do need to implement your method without recursion.
Trust in the code Luke. Yea right!

One solution is to do your own drawing. Otherwise, looking at CodeProject and CodeGuru.

CDC::Pie()
Look it up in MSDN, it includes a small example.

Hi,
In a dialog box a have a RichEditCtrl. I put a link in this richeditctrl like this.
CHARFORMAT2 userFont;
userFont.dwEffects = CFE_LINK;
descText->SetSel(0,descText->GetWindowTextLength());
descText->SetSelectionCharFormat(userFont);
descText->ReplaceSel("Click here");
How can I trap the click on that link? I've tried with
ON_NOTIFY(NM_CLICK,IDC_COMMAND,DoOnLink)
[IDC_COMMAND is the id of the RichEditCtrl]
but it doesn't execute the DoOnLink function.
Any ideas?
Thanks

Hello there,
I am trying to build a custom button in win32 c++ and trying to utilize the WM_MOUSEHOVER message in the Window Procedure. But when i try to compile the code it says WM_MOUSEHOVER is undeclared and TRACKMOUSEEVENT is missing!!! I have not defined WIN32_LEAN_AND_MEAN or any such thing. I am using VC++ 6.0 Pro. Please help me out and thankx in advance.

I guess you need to download the latest Platform SDK. My old MSDN Library (from 2000) doesn't know the message as well, but it works with the latest Platform SDK nonetheless.

I think youre right. I have tried the same code with the new mingw compiler and it works like a charm.  but the only problem is debugging  so i guess i have to work with it until i complete downloading the platform sdk (300MB+) on my dialup line  . Thankx man.

Hi.
I'm having problems using WS_EX_NOACTIVE flag for my CreateWindowEx.
I have this line:
MessageWindow = CreateWindowEx (WS_EX_NOACTIVATE| WS_EX_APPWINDOW,"MainWindow",......)
But I get an error:
'WS_EX_NOACTIVATE' : undeclared identifier
WS_EX_APPWINDOW is known, but not WS_EX_NOACTIVETE.
Is it just me or is this a bug?
I'm using VC6.0
Thanks alot

Disable the control's default property in resource editor.

Hello,
assume I have an array with dimensions 6x5 = 30 elements. The normal way to map an index value (ranging from 0 to 30) is this:
x = i mod 6, y = i div 6.
But now I want to access this array like a snail, so for increasing 'i' the elements should more and more near the center.
<br />
00 01 02 03 04 05<br />
17 18 19 20 21 06<br />
16 27 28 29 22 07<br />
15 26 25 24 23 08<br />
14 13 12 11 10 09<br />
The numbers in this table are the index values 'i'.
So for i=18, the element accessed should be x=1,y=1.
For i=29, x=3,y=2
For i=12, x=2,y=4.
Do you know a formula or fast algorithm to accomplish this? It should work for different array dimensions (so lookup tables aren't allowed...).
-Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Use std::vector or std::list.

Have you got whats my question???
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Are you just looking for a way to access the information stored in the array? Not sure I understood the question.

Not only access, I want to access it in a special order.
If you translate index values to x and y coordinates of an array, you normally do this using the mod and div stuff. But I want to access the elements like a snail, so for increasing index value we should get more and more to the center of the array (as in the table I posted).
