Try this:

Close the IDE and delete the file which has an extensio of .ncb and re open the project. You should have all your classes displayed.

Hope this helps. Smile | :)

Your code has problem

Y_Kaushik wrote:
while(fileObj.WriteString("strLine,buffer"))

I think its

while(fileObj.ReadString(strLine));

Now where do you want to write did you create a new file

On your code you open fileObj for write and also on the loop you want to read of it?

if we using below code

filewrite.Open(str,CFile::modeCreate | CFile::modeRead);

strLine.Empty();

while(filewrite.ReadString(strLine))
{
filewrite.WriteString(strLine);
fname += strLine + "\r\n";
}
filewrite.Close();
MessageBox(fname);

There is again same problem

You read and write to same file instead you said I read of a file and write to other file did you check your code?

while(filewrite.ReadString(strLine)) 
filewrite.WriteString(strLine);

What is this line doing? WriteString doesn't return a value.

What exactly isn't working properly? What is the format of the data in your buffer?

Hi all
i have developed an MFC application using VS 6.0
The problem is, the .exe is working fine on a system and its not stable on other system(its crashing).
On both of the system VS 6.0 is not installed. I copied the required MFC dlls manually to the WINNT/System32. There may be memory leaks in my application, but the systems are of same configuration ( 1 GB RAM, P4 3.2 GHZ CPU...), I should get the same results on both of the machines. Please suggest, where it might go wrong?

Thank you.
Ramana.

The application is a Client, When i perform any operation on Server, the changes should reflect at the Client. I used WinSock 2.2 version for implementation. The server is same, in both the cases. When i run the Server and Client on Machine1 everything is fine. But, when i run the Client Program Macihne2, Client program is crashing. A message is shown saying "The application requested the runtime to terminate".

As mail is system dependent, the chapters are perfectly useful. There may be a class or two in use, but you can just dig out the API calls used - and they are C.

You can even do COM from C if you're masochistic. Only a few months ago there was a a series of articles showing COM using C.

Showing a window always on top!!!

hi all,

I have a window that is initially hidden. After some time i need to pop this window after i have completed downloading some contents. After the window is popped, if i click on any otehr window then this should loose its focus. How can this be achieved?

I tried using SetWindowPos(&wndTopMost,....). But this failed as the window is displayed always on top( the focus is never lost) which is not my requirement.
Also i tried SetForegroundWindow() function, but this also displays the window on top always.
SwitchToThisWindow() call is advisable as per MSDN forums.

How can this be overcome? Frown | :(

Even with the HWND_TOPMOST flag on with SetWindowPos, if you click on other windows, the window in question does lose focus. Is just that, since it is always on top, it will always be visible.

If you just want to show the window on the top of the Z-Order then try SetWindowPos with HWND_TOP. That should do the trick. Refer to MSDN for more details on SetWindowPos.

Hope this helps. Smile | :)

Thanks. What you told is right. But the thing is loosing the focus is not enough, i sould also make the other window clicked by the user visible. Setting SetWindowPos with HWND_TOP doesn't help as the window is shown on the taskbar alone nad not displayed to the user.

Its something like a pop-up window that sould be displayed, when we browse any web.

Requirement is: Pop the main window after some content is downloaded. If the user clicks on any other window, the main app window should go to the background.

Have you used the SWP_SHOWWINDOW flag with SetWindowPos?

SetWindowPos(HWND_TOP, ......., SWP_SHOWWINDOW);

MSDN Docs on SetWindowPos[^]

If this doesn't work then try

ShowWindow(SW_SHOW);

MSDN Docs on ShowWindow[^]

Hope this helps Smile | :)
