Well, that's not surprising since every Win32 app uses kernel32.dll Wink | ;)

But that's a linking step, not a compiling step. You have to work out the compile errors before worrying about libs.

I was going to, just for giggles if nothing else, but you really should cut the size of the download down a bit. 4.30MB is simply too large for my 28kbs dialup connection. If you drop any executables and intermediary files, and include as small a sample data file as is needed to test the app I may have another go at it.

Ok, to get a clean compile I had to change two lines in your code

File BeepExtremeDlg.cpp line 12
#include "BipFile.cpp"
to
#include "BipFile.h"

line 121 - The buffer that is used by itoa() has to allocated before it is used
char * buf;
to
char buf[10] = {0};

The program still crashes, but it is now logic errors, not syntax errors.

Hello,

Does anyone know anything about classless ip addresses / subnetting with regards to the Windows Socket Api? Is there anything special that needs to be done in the code to support this?

Thanks,

Supressing MS Automatic Error

dmaclellan25-Nov-05 6:11

25-Nov-05 6:11

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

Right click on MyComputer.
then select Properties.
then select Advance tab.
then click on Error Reporting.
select Disable Error Reporting.

that is all.

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?

CDialog : Passing Back variables to the Parent's Dialog

14-Dec-05 6:00

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!

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

Re: CDialog : Passing Back variables to the Parent's Dialog

Gary R. Wheeler25-Nov-05 6:09

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);

Obtaining the name of the caller function

emmatty25-Nov-05 2:46

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

Gary R. Wheeler25-Nov-05 2:59

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.
