Question

I am facing a really very interesting problem with string.

My code is:

Dim stropt As String

stropt = " -i ""C:\Rajesh Prj\Video splitter\testvideo.wmv"" -start 00:00:00 -duration 00:00:10 -start 00:00:10 -duration 00:00:10 -sep -o short{000}.wmv"
'Dim strwithpara As String
'strwithpara = " -i """ + filepath + """ -start 00:00:00 -duration 00:00:10 -start 00:00:10 -duration 00:00:10 -sep -o short{000}.wmv"

System.Diagnostics.Process.Start(Environment.CurrentDirectory() + "\asfbin.exe", stropt)

with above code its working fine, but when I uncomment the middle two lines, its giving me :

error: The system cannot find the file specified

even though I am not using variable strwithpara but its generating that error in Process.Start.

But when I comment those lines (which are uncommented in code above) its working fine.
Please tell me what I am missing and also suggest to me what should I do to resolve it.

I am taking value in filepath variable from file dialog’s FileName property.

EDIT: I have also compared the values of variable stropt and strwithpara with “IF” condition and found those are same.

Check the value of Environment.CurrentDirectory() + "\asfbin.exe" and stropt using breakpoints and see if they match what you expect
