You'll need to format the DOS command to execute the program.<BR /><BR />Hope that helps.<BR /><BR />Shan Pin Koh <BR /> Mon, 18 Jun 2001 18:57:00 GMT Shan Pin Koh 2001-06-18T18:57:00Z https://ni.lithium.com/t5/LabVIEW/Linking-an-executable-inside-LabView/m-p/17942#M12348 Hi there,<BR /> I have a small DOS-based executable program that I want to use inside one of my LabView programs. To do this, I'm attempting to use a Code Interface Node or a Call Libaray Function. However, it seems as if both of these require the source code (that I do not have). Is there a way to do this then? Just link the executable? Thanks. <BR /> Mon, 18 Jun 2001 18:52:30 GMT https://ni.lithium.com/t5/LabVIEW/Linking-an-executable-inside-LabView/m-p/17942#M12348 Bonhomme 2001-06-18T18:52:30Z https://ni.lithium.com/t5/LabVIEW/Linking-an-executable-inside-LabView/m-p/17943#M12349 It sounds like you just want to run the DOS program as if you were running it from the DOS prompt.<BR /><BR />Try using System Exec.vi located on your Communications function palette to call DOS program.
