Re: how to remove space while writing data to text file using CFile in vc++

10-Sep-09 21:39

The line is wrong: you should replace it with

cTestFile.Write(csSetID, csSetID.GetLength() * sizeof(TCHAR));

Anyway, I doubt this is what you really want to do (i.e. Are you trying to write a wide-char text file?)?

Hi all,

I have a doubt whether Microsoft Excel will support data of unicode big endian encoded type...

I tried manually pasting unicoded big endian encoded data.. it was showing junk characters...

I have a doubt whether MS Excel 2007 will support Unicode Big Endian type for saving and opening..

Thanks,
Rakesh.

You can use SHFileOperation[^].

RemoveDirectory() only deletes empty directories. To delete files and folders simultaneously, use SHFileOperation().

You may use CImage class for the purpose, see CImage::Load [^] and, for instance, CImage::GetPixel [^].

Just in addition to CPallini's post.

If you decide to use CImage class you will notice that the GetPixel and SetPixel methods are slow. So if you need a fast pixel access you can use this[^] class with combination of CImage class.

Using CxImage[^] library could also be an option. Smile | :)

Just make sure you include <windows.h> (in example you can include it in stdafx.h, if you are using precompiled headers) before the include of zip.h and the errors must gone. Smile | :)
