Concatenate string from registry vb.net

Question

0.00/5 (No votes)

See more:

I've been unable to concatenate the name of the executable file to the returned "AppPath" value from the registry.

I can successfully do so with one application that has the returned value "C:\Program Files (x86)\AppOne\"
but another application returns the value "C:\Program Files (x86)\AppTwo\..."
with three trailing dots and I can't concatenate anything to this.

What I have tried:

Trimming the string with
mystring=mystring.Trim(Chr(46))
but that doesn't work.

Did you try something like this:
https://msdn.microsoft.com/en-us/library/system.io.directory.getparent(v=vs.110).aspx

You should be able to stop at the correct path then. Or you could simply use ToString.Split("\") and stitch the path you want to find with Path.Combine

You need to talk to the owners of the application that returns the incomplete path.

It transpires that the three trailing dots in the registry value indicate that the string is longer than what is displayed, in this case the string has 209 extra white space characters.
Now I know that, I have been able to concatenate the name of the executable file to the path.
Thanks for your input.
