My fault this member function is available is VS2002 and upward, it doesn't available for people using VS6.

you have two option for same, if you still want to use said CString function, either download the WTL classes or rip apart CString code from upward version of VS and include same in your source code Smile | :)

It just can't "disappear" like that! Either somewhere UpdateData is being called wrongly or some part of your code is making it behave like that.

Either you are setting "" in Setfocus option or UpdateData is not called properly.

dlg.DoModal(); // D'Oh! | :doh:

return TRUE;
}

Somethings seem HARD to do, until we know how to do them.

This is actually a known bug that comes about due to the size of the OPENFILENAME structure being used with MFC. You need to define _WIN32_WINNT to be 0x500, and set the lStructSize member to to 88 (instead of 76). You might also need to use GetOpenFileName() instead of CFileDialog().

You need to determine the programs current working folder (CWD). Have a look at GetCurrentDirectory() or _getcwd(). You might also consider GetModuleFilename(NULL, ...).

Use GetModuleFileName to get full path of your program and then use PathRemoveFileSpec to get the parent folder of your program.

For e.g. if your program is in C:\Program files\Myprogram then path returned by GetModuleFileName is C:\Program files\MyProgram\YourProgram.exe and then PathRemoveFileSpec removes the file part and returns C:\Program files\MyProgram.

BTW, if you specified only the filename without path, "goodssale.dat", it creates file in the current working directory, and the fullpath to the executable can be obtained from the first argument of the argument vector (commandline parameter) of main function.

And for more info you can check that file is exist or no with FindFirstFile if you want to keep values of file if it's exists.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
