Re: CDialog : Passing Back variables to the Parent's Dialog - C / C++ / MFC Discussion Boards

Hi all,

Fairly new to this so bear with me...I have an app which, due to a Macromedia issue we have, crashes on an occasional basis. When it does I get the microsoft automatic error reporting dialog saying "Sorry but your application..blah blah....please send your error to Microsoft"

All I want to do is supress that Dialog so the user never sees it but no-one seems to know how to do it.

Any help would be greatly appreciated!

Thanks in advance
DM

That's just what I need - thanks very much! Big Grin | :-D

Trouble is now...this app is going to run on 6000 machines around the UK, I'm going to have to do this in the code somehow Unsure | :~

I'll have a dig around and see what I can come up with.

Once again, thanks for your help.

Hopefully these are turnkey systems, and not end-user systems since you are turning off this message for ALL programs running on the computer.

Now, supposing you actually caught program exceptions at some high level in your program, won't that ALSO stop the message from appearing?

Hi Blake, sorry for late reply, been away!

If the settings are correct, it only supresses the error message for a specified app which is just what we want.

As it happens, it turned out to be a hardware issue (sorry Macromedia Blush | :O

) which was easily resolved but you are right, the program exceptions would have worked as well.

Thanks for the help!

CDialog : Passing Back variables to the Parent's Dialog

Hi,

Is there any way to passing back to the parent dialog values of the child's Dialog variables ?

For example :

CCreateCategoryDlg dlg;

if (dlg.DoModal() == IDOK)
{

// In this point i want the access the strings of the dlg.ListBox

}

Regards,
George

You can add public member variables or functions to the CCreateCategoryDlg class that return the results. Here's an example:

public CMyDialog : CDialog {
public:
  virtual void OnOK();
  int GetResult();
private:
  int Result;
};
void CMyDialog::OnOK()
{
  Result = list_box.GetCurSel();
}
int CMyDialog::GetResult()
{
  return Result;
}

Note that you can't reference the list box in the function GetResult(). At this point, the dialog window and its child controls have already been destroyed. This is the reason for the OnOK() handler, which is called when the user clicks the OK button, before the dialog is destroyed. Save the contents of the controls in the OnOK() handler, and then return those saved results in the "Get*" functions.

Overlapping control -problem

Hi,

Iam working with a ListControl whose parent is a dialog. In one the cell of the listcontrol,I place a tree control which on doubleclicking should open up & overlap the dialog control.

I achieved the treecontroloverlapping by writing as follows:

treeControl.SetParent(GetDesktopWindow());
treeControl.ShowWindow(true);
treeControl.BringWindowToTop();
treeControl.SetFocus();
treeControl.MoveWindow(500,300,400,200);

Now,the problem I have in hand is that the overlapped treecontrol is not active.Can't do anything over there.
Tried "EnableWindow","SetActiveWindow" etc.but the overlapped treecontrol is not getting enabled.

Any help is appreciated...
Thanks...

Why not make the tree control's parent the dialog instead of the desktop window?
Just insert it in Z-order after the list control so that it will appear in front of the list control.

HiBlake,

I fixed the problem..
I had to Modify the style after setting the parent
m_gridControl.SetParent(GetDesktopWindow());
m_gridControl.ModifyStyle(WS_CHILD,WS_POPUP);

Thanks

Obtaining the name of the caller function

Is there any way to obtain the name of the caller function in VC++?

eg:
Func1()
{
Func2()
}

I need to get the name of Func1() from Func2() using code.

Any help would be appreciated.

Thanks,
John

Unfortunately, there's no way to do that directly. The compiler does create a #define symbol called __FUNCTION__, that is the name of the current function. You could modify your code as follows:

void Func2(char *caller);
void Func1()
{
  Func2(__FUNCTION__);
}
void Func2(char *caller)
{
  TRACE(_T("Func2 called by %s.\r\n"),caller);
}

Everywhere you call Func2 use Func2(__FUNCTION__);.

This may be a VC7.1 feature, as that's the only compiler where I've used it. There's no option required to enable it. The value is the fully-resolved name of the function, e.g. base1::base2::...::function.

Look at the DbgHelp API, in particular the symbol handling functions.
There are articles here on CP about 'call-stack tracing' that will also help.

Hello,

The callstack[^] is a usefull place to look for a function address and name. The only problem is that this only works in debug builds. Do you need this also in release builds? If so, you have to provide the *.pdb file with your application, which reveals vital information about your application.

Hope this helps.

Setting aside the problems of getting the human-readable name of functions, walking the callstack at runtime is problematic. See Don't trust the return address[^]

PJ...is your library supposed to work with VS 2005?

I have an app compiled with VC6 that's using it without any problem...however when I try to compile the project under VS2005 the linker gives the me following error:

smtp.obj - error LNK2001: unresolved external symbol "unsigned int (__stdcall* ATL::g_pfnGetThreadACP)(void)" (?g_pfnGetThreadACP@ATL@@3P6GIXZA)

Little help with that maybe? This is a plain windowless Win32 application. No MFC, no ATL...
