Thanks for your help - but that's not what I need...
I need to look for a files that have the same file name each time, but have different extensions.
For Example, in my directory there are the files:
file.001
file.002
file.x
file.y

so, I don't need to find the files file.x or file.y. I only need to find the files that have an extension that consists of numbers.
The problem is that when I search for files in the format: "file.*", it finds the files named file.x and file.y which I don't need.

ok for(.............etc.)
sprintf(fileFound, "%s\\file.00%.1d
",ARRAYOFCONST((folderPath,i)) );
now you can search for ectintions
from 001 to 009

yes - but I don't know what the maximum number the extension could have. There could be a file named file.9999 for instance..
so I can't search until infinity. That's my problem.

Maybe there is a way to check if the extension contains only numbers or something like that. Do you know?

I dont remember the function name but try this

sSearchPath.Format("file.*");
BOOL bWorking = f.FindFile(sSearchPath);
int j = 0, i++;
while (bWorking)
{
CString strFileEx = ExtractFileExt(f.GetFileName());
while(strFileEx [j] != '\0' )
{
if(!((int)strFileEx [j] >= (int)'0' && (int)strFileEx [j]<='9'))
i++;
}
if(i>0)
//do what you want to do
bWorking = f.FindNextFile();

}

But what is the function "ExtractFileExt"? my code doesn't recognise it. do I need an include for it or something?

Why not just use PathFindExtension()?

Yes, it's called isdigit().

For each file found, including file.x and file.y, simply check the extension to see if it is all digits or not.

what you can do is determine the extension of the file using GetFileName and GetFileTitle. Then for each charcter in extension check if its a digit using isDigit function. If all the characters in extension are digit then keep file else move to next file.

You can use PathFindExtension() to get a pointer to the extension part of the filename, and do string comparisons from there.

Figure out what the command ID is and send the Notepad window a WM_COMMAND message, passing that ID.

Hi shortwave,
You can use findwindow for get hwnd from application and use
sendmessage(hwndapplication,wm_command,idmenu(item),handlemenu);

You can tell the control to scroll to the last line with code something like this:

m_EditControl.LineScroll(m_EditControl.GetLineCount());

I'm developing an app which has to read binary files. The data in these files can be stored as various sizes, 1-byte 2-byte 4-byte and 8-byte. So when reading the data I need to read it as char short int and long. This is not really the problem, but reading the correct byte order is. At the begining of the file there is a flag to indicate whether the following data will be using Little-Endian or Big-Endian method.

I'm not sure how to deal with this. Could somebody please point me towards a tutorial/article which better explains all this and demonstrates how to deal with the various encodings.

Thankyou

Yes <iostream> is already included
