I need to execute an external application prior to executing latex.exe to prepare a new file to be imported from within the (La)TeX input file.
From another topic, I got an rough info that we can use \write18 command. But I don't have an idea to execute it.
Here is my file structure:
MyProjectDir ---Main.tex ---SourcesDir -----ExternalApp.exe
EDIT 1: In TeXnicCenter (latex editor for windows), there is no PreProcessor. Only PostProcessor is available. Therefore, I cannot execute it in one go. Executing it manually will be a tedious job.
