I''m getting a strange side effect when I use the open file name dialog. After I select a file, some of my code stops working. Here is exactly where i am having the problem: Log( "Everything before this shows up\n" ); GetOpenFileName( ( LPOPENFILENAME ) &ofn ); Log( "THIS NEVER SHOWS UP....why???\n" ); The function Log() is one that I have made, it just copies the message to a log file. After I call GetOpenFileName, the log stops working for the rest of the duration of the program. Does GetOpenFileName do anything funky that I should be aware of?

I''ve never used it and don''t know the syntax, but are you sure the function isn''t a callback?

Trying is the first step towards failure.

Here is the Log() function that I use. I''ve used it forever and never had a problem.

//-----------------------------------------------------------------------------
// Name: Log()
// Desc: Adds to the logfile
//-----------------------------------------------------------------------------
void Log( char *str )
{
static bool first_time = true;
ofstream fp;

if( first_time == true )
{
fp.open("log.txt");

fp << "//-----------------------------------------------------------------------------\n";
fp << "// File: log.txt\n";
fp << "//\n";
fp << "// Desc: Log File of the application''s activity\n";
fp << "//\n";
fp << "// Copyright (c) 2001 Dan\n";
fp << "//-----------------------------------------------------------------------------\n";
fp << "\n";

first_time = false;

fp.close();
}

fp.open("log.txt", ios::app);

fp << str;

fp.close();
}

Oh geez, right when I post this it hit me. Mr Anonymous Poster is correct. It does change the directory. Thanks you!
