No. But you have to make sure that the transferred file is identical to the original one. You may use a tool such a Windiff to verify it.

I tested it with windiff.
I am getting message that created file is more recent.
I am not getting what can be done next?
Here I am giving You code for writing that file.

if( nFile != NULL )
{

numwritten = fwrite( recvbuf, sizeof(char),length, nFile );
fclose(nFile)

}
else
MessageBox(NULL,"Problem opening file",NULL,NULL);

Do I need to use feof or any other commands?

Thank You...

That's ok.
Now, what about the differences? Can you see any difference (using Windiff, select the first item and then click the expand button)?

I expanded it and I got some Encrypted language contents.
but on clicking on edit right file and left file I got .txt file version of both files.
There is a differeence in both files.The half of the file is same and I am getting "ÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌ" charachters for rest of file(in created file).
I am not getting why there is such difference.

Thank You....

Probably the buffer you're writing to the output file does not contain the whole info. I think you have to check how many bytes are actually transferred between the client and the server.

Before I sent contents of file I am sending the length or size of file.
And I am recieving lenght of file.
I am using that length in recv() function.
It is working fine for .gif file.

Thank You...

I suspect you need to run your main code in a seperate thread so that your progress bar is responsive.

Please, reply here, I don't respond to emails b/c I don't give out my address.

I'm sorry, but you'll need to read up on multithreading, if you don't understand what I meant. Yes, you can put it in your status bar, I'm sure there are articles on how to do that.

Hi,

Why you put the code inside the custom draw function (OnNMCustomdrawProgress1) of the progress bar itself. This function is called only if the Progreesbar is having OWner draw style.Whether you want to show another progress control when the custom draw function of the progress1 is called???.

thanks,

Nitheesh

Hi,

Place your ProgressBar Creation code in OnInitDialog (override it) and make control hidden. Then in your button click event handler make it visible and set its bar position's.

Or

you can place a progress control bar and make it visible false. then do in button click event handler as said above.

And increment the bar position in the list fill function.

thanks

So which is it, empty or invisible?

Did you mean to create the control at run time rather than at dsign time?

How do I change "static" text in window

Kwanalouie4-May-08 6:57

Kwanalouie

4-May-08 6:57

I'm using Visual C++ 6.0 - I'm new to windows programming.
I have a pop-up window where users enter data. It is setup as dialog using Visual C++. Sometimes I would like to display a note in this window that says "inches" and other times I would like this note to say "millimeters". I learned how to put up static messages, but I don't understand how to change them based on a variable in my C++ code. What is the simplest approach? Thanks ahead of time.

Mark Salsbery4-May-08 7:07

Are you using MFC? If so, you can add a CStatic control variable
to the window class, and use the CStatic::SetWindowText() method to
change the control's text.
You should be able to add the control object from the dialog editor...
right click the text control and chose "Add variable..." (I can't remember
exactly in VC6).

*edit* Actually, adding a string variable for the static control and using <br />
DDX is another possibly simpler MFC solution.  I seem to have neglected that<br />
previously

If you use straight Win32, you can use the SetWindowText() API directly
on the control, something like:

HWND hwndControl = ::GetDlgItem(hwndDialog, IDC_MYSTATICCONTROL);
::SetWindowText(hwndControl, _T("New Text!"));

Thanks for the reply. Your answer changes the title of the window, but it led me to find the function:
void SetDlgItemText( int nID, LPCTSTR lpszString );
which seems to work okay for what I want.

Hamid_RT4-May-08 19:36

For SetWindowText you need to a handle to controls but with SetDlgItemText you can use of control id.
