SUMMARY
Windows help files (.HLP files) can be written such that selecting a designated topic executes a Windows-based application. This is done with the ExecProgram macro. If the desired application does not reside in the same directory as the .HLP file, a full path to the .EXE must be specified. An invalid path produces an error.

SYMPTOMS
Attempting to execute an application with a full path causes Windows to display the following Help message box:

Unable to Run Specified File.

CAUSE
A common mistake is to incorrectly specify the subdirectory delimiters in the path description.

RESOLUTION
The Windows Help Compiler can recognize escape sequences expressed using the backslash (\) character. When using the ExecProgram macro, four backslashes (\\\\) separate each directory in a full path description:

"ExecProgram( &quot;c:\\\\winapps\\\\excel\\\\excel&quot;, 0 )" With HC31.EXE version 3.10.505, you would use only two backslashes: "ExecProgram( &quot;c:\\winapps\\excel\\excel&quot;, 0 )" Additional query words: 3.00 3.10 4.00 95
