To create exe file

I have to create Exe file in vb5 or vb6 based on th document type i.e. *.doc(word document)/*.Xls(excel document)/*.ppt(power point document)
the Exe should be in such way that it takes input from InputDirectory such way that it takes input from InputDirectory i.e. In types is *.doc
or *.xls or *.ppt .vb executable based on document type it will Instantiate (i.e. Run Application) word/excel/power point & make these
print the document to a file i.e *.Doc.prn,*.xls.prn or *.ppt.prn in the OutputDirectory .My question is how to input to the Exe through
InputDirectory i.e. through form or Directory control or file list contol box & it should run the word/excel/power point application depending
on the Document type & make these print the document to file i.e, *.doc.prn /*.xls.prn/*.ppt.prn should be in outputdirectory, so should
I create ouputdirectory sothat it create *.doc.prn,*.xls.prn,*.ppt.prn automatically & store as print file(*.prn).
