Hi
I know my answer is a stupid one... but still
You want to write again from beginning. its equal to close the previous handle. Open is any other mode that delete the file and create it. then close again.( this is equal to close the handle and delete the file). then open in notruncate mode again.
souds funny I know. I will try to find out better options...

Hi,
Another option would be to set the filecursor back to the beginning using CFile::SeekToBegin (); and then emptying the file by CFile::SetLength (0);

Yes your one is a better solution.
I have no idea about SetLenght funtion.
Thanks

Hi!!
I m working on an mfc sdi application.
I hav a dialog in which , i have "SHOW FILE" button. On it`s click event, i want to show the file on the same dialog. But, before clicking the "SHOW FILE" button, i want a small dialog only. Now, I hav two problems:
1. In which control, should I display(show) the file to the user?
2. How to set the dialog size at run time?
Thanx a lot

ABout your first question which type of file do you want to display? image file, text file, HTML file....
for changing the dialog box size...
MoveWindow()
SetWindowPos()

Hello
For Text File you can use CEdit Control with Multiline option set.
Or if your file size is large and you want some extra thigs to display like changing the colour of text ...
you car use RichEditControl.

Hello Friends,
Can any one tell where I can find the study materials (on the internet) for function pointer in C and C++ ?
How function pointer are used in the implementation of callback function in c and c++?
Where I can complete details of function pointer on the internet(where I can freely download demo codes for function pointers in c OR CPP).
I would be gratefull if anybody can help me in this matter
From
Philip.

why don't you ask here particuliar questions about function pointers ?
there are definitely several C/C++ experts which can help much than reading lines on the internet...
for demos also, there are plenty of examples on CodeProject too...

Hi Guys,
First of all i really thank to all as i got all the answers to my doubts.
This time i have some interesting problem. In my projects thre are more than 300 classes. But in the class view it's only showing 1 class. Another interesting the same code when it was in the original directory its showing all the classes but when i placed the same code in a different folder it's showing only one class. My team mates are also facing the same problem. Please help me if you know the reason.

Sometimes Visual C++ 6 class view dies, and you need to make it look again at your classes.
Close visual c++
using taskmanager, kill the msdev process if it doesn't go away quickly.
go to the location of your project.
delete the .ncb file. (eg. myproj.ncb)
rerun vc++.
expand a project in the class view. see the "1983 files to go" line get smaller
enjoy all your classes!
Of course, this applies to v6. I have no idea about 2003-2005, etc.
Iain.
