system exec.vi issue

[slugger]

hi all

i have a dos program, that when run from the dos prompt (called by command.com at windows > run) works with the following syntax:

c:\imagecompare.exe c:\file1.bmp c:\file2.bmp

OR

imagecompare.exe file1.bmp file2.bmp

if run from c: in the dos prompt.

i have tried every way described of doing it using system exec.vi but nothing seems to work.

when called this way the dos window just sits there with a flasing cursor.

so my first question is:

what is the name of the DLL i need for XP to show dos text?

i have tested command.com using system exec by the following command line input:

command.com /c dir

this popped the window up for about a second. but i had no std output. should i have seen output from this vi?  

any help would be appreciated

Hi slugger,

you have to use quotation marks.

cmd /c ""C:\imagecompare.exe" "c:\file1.bmp" c:\file2.bmp"" should work for you.

Hope it helps.

hi mike

well tried all that and it still didnt work !!

got really annoyed with it and tried the following:

created image.bat with the following text inside c:\imagecompare.exe c:\file1.bmp c:\file2.bmp

then directly from the command line ran "c:\image.bat"

this worked.

thanks for pointing me in a direction i hadnt tried

Hi slugger,

i forgot one quotation mark. sorry for that.

Can you upload your vi, or a picture of it?
