I created a dialog box using the resource editor. I am wondering how to get the CWND from this so I can create controls during run time.
Thanks

Do you use MFC?
If YES, the CDialog class what the Visual C++ Wizard created is derived from CWnd. So, you can use the a member of type CDialog on every place where you can use CWnd.
Sample:
<br />
CMyDialog dlg;<br />
dlg.DoModal();<br />
...<br />
dlg.SetWindowText(_T("Hi!"));<br />
...<br />
CWnd* pWnd = &dlg;<br />
...<br />
pWnd->SetWindowText(_T("Hi!"));<br />

Nope, not using MFC, using the resource editor and the winapi.

You get the HWND of the dialog (not "CWND") as the first parameter to the dialog box function. Also, if the dialog is modeless, its HWND is the return value from CreateDialog().

If you're running under WIn API, you'll have somewhere in your code a place where you create your main window. This is your CWnd. To add controls in your CDialog, just pass a *CDialog instead of a *CWnd, since CDialog is derived from CWnd (and this, not only in MFC).
Finally, if your main win is your dialog, you may pass NULL pointers to create the controls (see MSDN)
Hope this helps-

Hi :
This must be easy for some ... but I am having trouble getting it to work.
My project is a dialog form, and it has only 1 button - IDC_BUTTON1.
The following are codes associated :
void CYDlg::OnButton1()
{
// TODO: Add your control notification handler code here
AfxMessageBox("Single Click") ;
}
void CYDlg::OnDoubleclickedButton1()
{
// TODO: Add your control notification handler code here
AfxMessageBox("DoubleClicked") ;
}
Clearly, if I click on the button or twice, it should show the appropriate messag. However, I am always only getting "Single Click" no matter how many clicks I try.
Am I missing something ?
TIA.

When you double-click something, it first receives a clicked message (for the first click) and then a double-clicked message (for the second). Since you show a message box on the first click, that disables the dialog (since the msg box is modal) making the button unable to receive the second click. Remove the message box from your OnButton1() handler and you'll see.

You are right ! Thanks for the explanation.

Why would you want to double click on a button
Never seen that, done that or will do that.

Hi :
One never knows .... I am just exploring VC++.. and since the wizards show that it is doable .....
Here's a dumb question then. Follow up from previous mail ... what if I want to open dialog1 if user single click, and open dialog2 if user double click.
Does this mean this is not possible, or have to done in different way ?
Cheers.

Maybe it's possible, maybe not. I don't want to know.
Go to the next page of your book and start with more interesting things;P

Call LoadImage() and use the LR_LOADFROMFILE flag. This will get you an HBITMAP which you can use with GDI functions.

Hi,
I am developing a TAPI application to send and recv data. I was able established the connection between the application. Now I want to send and recv data between them. I'm using ReadFile() and WriteFile(). But when I try to set the comm state, it gives me an error. Some times it gives an error INVALID_HANDLE in Write file(). How to get the comm handle ? I have used the LPVARSTRING to get the handle. Is it correct? How to use the WriteFile() and ReadFile() function.
Pls help...

Hi,
I've been working on some ATL components, and I use VB as the testbed for them.
Normally I compile the DLL and register it, set a breakpoint in the code, and point to my VB application as the debug executable, and when my function get's called my breakpoint is hit, and I'm into debug mode.
BUT all of a sudden, the breakpoints are just being skipped.
Is there something obvious I've missed?

Hi all,
What is the win32 API equivalent of 'malloc' and 'free' ?
Which of these is better ?
thanks in advance

The C++ language exists outside the Windows world, in fact it was even concieved there. So win32 has nothing to do with it. The C++ equivelent to the C functions 'malloc' and 'free' is 'new' and 'delete'. You should always use the C++ versions.

No offense, but I don't really want to encourage the creation of another VB developer.

Again, you can screw up a C/C++ program just as easily as a VB program. OK, maybe not
as easily, but it's certainly doable. - Jamie Nordmeyer - 15-Nov-2002

Because you can't malloc and delete, new and free, so it's easier not to mix them up. Because you get constructors and destructors out of it ( man, do I miss destructors in my .NET world ).

yeah, i guess that applies to C++. but the original poster didn't mention C++, only Win32.

Well, the fact that he said Win32 makes me think he's probably a newbie, almost certainly using C++. If he's not, then my answer will make clear that the stuff I've said does not apply. I presume I'm right in thinking that the Win32 API does not provide an alternative malloc ?

there's a whole host of allocation functions in Win32: Global/Heap/Local/VirtualAlloc and so on.

Thanks a lot for help guys .
I dont think i can use new and delete because i want to use realloc.
I really dont know anything about heap/global/local allocs.
since mike said its better to use CRT, i will stick to malloc.

I believe that is so. Why do you want to use realloc ?

I am going to ask him, because AFAIK, new and delete also give you everything he mentioned. I strongly dispute the wisdom of using C memory allocation in C++, but Mike is a hell of a smart guy, so I'm keen to hear what he says.
