Have you tried:
ofn.lpstrFilter = _T("Bob files (Bob*.*)\0Bob*.*\0");

We appear to think alike becasue it was the very first thing that I tried. 
Unfortunatly this causes everyfile in the entire directory to be displayed,
it no longer even limits the file to the .txt files.
I know you can delimit a string in borne shell or perl the way I want but I have never tired it in windows.

I tried this and it worked fine:
void main( void )
{
OPENFILENAME ofn = {0};
ofn.lStructSize = sizeof(ofn);
ofn.lpstrFilter = _T("Bob files (Bob*.*)\0Bob*.*\0");
GetOpenFileName(&ofn);
}What else do you have?

After messing with this a bit I also got it to work. Thanks alot.
I am now having issues with a variation of this, I am trying to get the name my save and load dialog boxes display, to be dynamic based on the file the user is currently working on.
My application creates several files based on the original file.
For Example: if a user names the original file bob my application will create a bob_section1.txt and a bob_section2.txt.
The purpose of this filter is to only display the files that were created durring a single run of my application.
bob.txt
bob_section1.txt
bob_section2.txt
I can get the filter to work if I statically put in ofn.lpstrFilter = "Bob files (Bob*.*)\0Bob*.txt\0"; Or using a character array called Filtername[256] and building the same filter.
Filtername[256] = "Bob files (Bob*.*)\0Bob*.txt\0";
ofn.lpstrFilter = Filtername;
What I am trying to acomplish is the following
Filtername[256] = "Section files (.txt)\0Filename*.txt\0";
Where Filename is the name of the current file. This way it will display the created file and all of the secondary files created from it.
I have tried
strcpy(Filtername, "Section files (.txt)");
strcat(Filtername, "\0");
strcat(Filtername, Filename);
strcat(Filtername, "*.txt\0\0");
This however fails miserably and I get either No files to display or every file in the entire directory. I am pretty sure it is an issue with the null charcters not getting put into the character array correctly but I am not sure what exactly is going wrong.
Any Ideas.........

Drat, I thought as much... Is there anytype of work around for this or is my dream of dynamic naming dead.

You could use memcpy().

Thanks for all your help I got it working now.
The final version came out looking like this
// Creates appropriate filer without loosing the embeded NULL characters
strcpy(Filefilter, "Scenario Files (*.txt)\0");
strcat(Name,"*.txt\0\0");
strcpy(&Filefilter[23], Name);
ofn.lpstrFilter = Filefilter;
Again thanks for all of your advice David

strcpy() and strcat() won't work with embedded \0 characters. You'll either need to use memcpy() or plug the \0 characters in manually.
Another option would be:
char szFileFilter[256];
sprintf(szFileFilter, "%s%c%s%c", "Scenario Files (*.txt)", '\0', "*.txt", '\0');

If I put an activeX control on a CDialog in an MFC dll, the dilaog doesn't come up. WHy is this? Can I get around it somehow?

Make sure that AfxEnableControlContainer() is called at the begining of your InitInstance function (sorry, for dll I can't remember if the function is the same name).

My app has a processing thread, when the thread end it sends (Postmessage) an WM_USER to the main frame (using a pointer that is initialized into CDocument, before that the thread starts, using AfxGetMainWnd).
Then that message is used to know that the process is end.
It works perfecly ,.... but I have notice that if the user, during the processing, opens (and explore) the program menu the user message will not reach the main frame, and I can't know that the thread is end!
Does somebody know what is the reason of this?
Thanks.
Cheers,
Russell

I think the WM_USER message sent by your thread can interfere with another messages used by Windows. There are many reserved messages defined as WM_USER + num in Windows header files. So it is possible that your message is interpreted in an unexpected way.
In order to avoid collisions, you can use "registered messages" instead, defined with RegisterWindowMessage function. The corresponding handler can be defined using ON_REGISTERED_MESSAGE macro.
Or you can post the WM_COMMAND message with a unique command ID which is not used by any menu item.
Alternatively, you can found another ways for detecting thread completion. For instance, in your main application you can use something like this: WaitForSingleObject(*myThread, INFINITE), where myThread is a pointer to CWinThread object, returned by AfxBeginThread.

Thanks :-Dfor your resp.
the message collision could be athe problem.
I'm also thinking that some function used to draw the menu can get my message and it doesn't like it and so delete the message.
Do you know if the "registered messages" can solve this problem too? (I haven't used they before)
And, finally, WaitForSingleObject looks like a function that will lock the application in a loop waiting that the thread ends, Am I right?
Thanks
Cheers,
Russell

The RegisterWindowMessage function defines a new window message that is guaranteed to be unique throughout the system [MSDN]. Therefore no collision will occur.
The usage of RegisterWindowMessage in context of MFC is simple. In your frame class (*.h file), define a handler like this:
afx_msg LRESULT OnMyMessage( WPARAM, LPARAM);
Then in *.cpp file declare a static variable:
static const UINT myMessageID =
::RegisterWindowMessage( "put here a long string");
And then in BEGIN_MESSAGE_MAP area add:
ON_REGISTERED_MESSAGE(myMessageID, OnMyMessage)
* * *
The WaitForSingleObject can be used in non-blocking form:
if(WaitForSingleObject(*myThread, 0) == WAIT_OBJECT_0)
{
}
else
{
}
You can specify a non-zero timeout interval in WaitForSingleObject.
Hope your problem does not have other subtle reasons.

/*MYSQL *mysql_real_connect(MYSQL *mysql, const char *host, const char *user,

goto exit_here;
}
and now plz send me code to login

Hello,
I have a application UI developed using MFC, however the contents of the controls i.e. strings that needs to be displyed on the various controls(static texts, buttons, lilst boxes etc.) on the dialog boxes are determined at run time. So I need a Intelligent control resizing and positioning utility so that asthetics of the dialog box is maintained when one or the other control is stretched from its statically designed area.
This utility is also required for other purpose : I wish to internationalize my application and I do not want to maintain seperate resource DLL for each language supported by my application.
Any pointers or clues in this direction will be helpfull.
Thanks
Suyash
