running CONVERT from Windows

[john2]

If i use a DOS box (CMD) and run this

CONVERT c:\path\picture.png c:\path\picture.jpg

it converts the file as expected!

BUT

If I run the exact same command from Windows's Start>Run then nothing happens!!

Why does CONVERT care where I run it from?

I need a way to call CONVERT from Windows . I know I can use the COM bject but I need it this to be DOS based

TIA

It should make no difference which way you do it. (I have just checked that again.) It guess that you might have made a typo when using the Start box. A possible source of error is the setting of the PATH variable, as Convert is also a Windows system command, see http://www.imagemagick.org/Usage/windows/#convert_issue for details. There is nothing wrong with using the DOS command instead of the COM+ object and the code should work just the way you applied it.
