You need to call dlg.DoModal in order to make your dialog appear on the screen. But as DoModal doesn't return until the user close it, you'll need to call GetDlgItem(IDC_COM1)->EnableWindow(FALSE); in the OnInitDialog from your dialog.
Hope this helps...

-sometime EnableWindow is (FALSE)
-sometime EnableWindow is (TRUE)
how to control this??
OnInitDialog is only one time or not.
onther class is control dialog EnableWindow or not.
//my code
//LeftTreeCtrl.h
void CLeftTreeCtrl::EditCategory()
{
CAddCategoryDlg dlg;
dlg.m_strcom1=cry->m_strCom;
dlg.GetDlgItem(IDC_COM1)->EnableWindow(FALSE);
if (IDOK == dlg.DoModal())
{
//code
}
}
void CLeftTreeCtrl::AddCategory()
{
CAddCategoryDlg dlg;
dlg.m_strcom1=cry->m_strCom;
dlg.GetDlgItem(IDC_COM1)->EnableWindow(TRUE);
if (IDOK == dlg.DoModal())
{
//code
}
}
i wrote this two function.
this is not access.
Other class can not control other dialog class.
please answer me.

Yes, OnInitDialog is just called once when you call DoModal. But, when you create your dialog again, it is of course called again. If you want to enable or disable your control but without knowing it before, I suggest you to add a member variable to your class dialog (say bEnable for example) and add a member function:
void CYourDialog SetEnabled(BOOL bEn) { bEnabled = bEn; }. So you call this member function before calling DoModal (and after creating your dialog) and then, in OnInitDialog, add this:
...->EnableWindow(bEnabled);

Hi..
How to find any control on dialog has changed without tracking setfocus() lostFocus() of each control. As there are too many screens & too many controls on those screens. I just find out, if need for Save on OK Button or not needed.
I'm saving data when user press OK.. I want to check that if user changed something then only I run sql to update otherwise nothing should be done...
Can anybody help me?
Regards
Sumit Kapoor

Maybe another solution would be to have a member variable in your Dialog class that will be at TRUE hen something changed. So at initialization, this variable is set at FALSE and whenever you change something, set this variable to TRUE.

Sir Ji,
That's what I'm asking, When to set this variable TRUE, as your suggestion showing that I need to track all controls for changes..that I don't want to do. I just want to find out, User changed any control's value or Not? if changed then I have to save otherwise Ignore on OK Button.
Just Think & let mw know if any idea?
Thanks

I've built a client server application built in visual c++ sp5 inheriting from the CAsyncSocket class. Also i am spinning of a thread when my application starts which is used only for logging purposes. My problem is that the application sometimes just disappears without giving any error message. i've put try catch blocks everywhere and have been as defensive as possible but this is happening at random positions so am not sure what to do at this point. Any ideas why this might be happening? The operating system is windows 2000 server and using a intel P4 HTT machine.

Try rebuilding all once again . This happened to me .

I'm attempting to port a DirectSound application I wrote in VC# (.NET 2003) to VC++ (.NET 2003).
I've almost ported the entire code, but I'm stuck on one line, and would really appreciate it if somebody could help me out on this.
The line in C# is:
MemBuffer = (short[])(AppCaptureBuffer.Read(StreamCapBuffReadPos, typeof(short), LockFlag.None, 50000));
MemBuffer was previously declared as:
private short[] MemBuffer;
How would I do this in C++? My problem is with the "typeof" keyword in C#. It signifies the returned data type.
C++ doesn't appear to have the "typeof" keyword. How do I write this in C++?
Thanks!

You could try using depends to see the function exports. However I am guessing that all you are seeing are the mangled C++ names.
If this is so, without the header file I would find it hard to prototype the function names and parameter list.

If you are using Microsoft VC++ and you can get the decorated name, you can then use the undname utility from MS to show the parameters and return type. For example:
If the decorated name is ??0CLogFile@@QAE@VCString@@_N1@Z, use the command as shown
D:\>undname -f ??0CLogFile@@QAE@VCString@@_N1@Z
Microsoft« Windows« Operating System
UNDNAME Version 5.1.2600.0Copyright (c) Microsoft Corporation. All rights reserv

>> ??0CLogFile@@QAE@VCString@@_N1@Z == public: __thiscall CLogFile::CLogFile(cla
ss CString,bool,bool)

If the name is not mangled when you see it in Depends I don't think there is any way to get it

I used AfxBeginThread() to create a new thread, which would access some objects, in a member function of the class CMyClass. ( The CMyClass object is a member variable of the class CMyDialog. These "some objects" are also members of the class CMyClass )
Now, I'd like to destruct the CMyClass object while a button in my dialog (an object with type CMyDialog) is pressed. But the thread controlling function is still accessing some of its member objects in a loop. How could I savely delete these objects and end the thread savely when the button is preesed? Is there any standard step to solve this problem?
I've also tried to use the function GetMessage() in the thread controlling function, but when I used the debug mode in Visual C++ and breaked at where GetMessage() was, I found the thread would be destroyed immediately after
executing this line. What's wrong with it?

Sounds like you need to tell the thread to finish up
as you cant just kill it inthe middle of things
Interthread communications issues ...perhaps you might like to Post it a message
