Hi
I am learning to use BizTalk what is the correct syntax to check if a folder exists, I am attempting to use this line of code in an Expression editor but am getting an error
bResult = System.IO.Directory.Exists(@”c:\TestFolder”);
bResult is a boolean.
The error I receive is:
Inner execption: The filename,directory name, or volume label syntax is incorrect
Thanks

Not sure. I copied your line of code into an expression shape and it worked fine for me using 2006 R2

Hi Greg
Thanks so much for all your help with my basic issues/questions, I really appreciate it.
I took the same BizTalk application and changed the Application name under Configuration ->Deployment and deployed it and this time it did the check without issues. I had also added some code to create the folder if it did not exist and this also worked and created the folder. Excellent!
To try test and learn some more I changed the path to attempt to create another folder, deployed but this time nothing happened(no errors either). I had to changed the app name again to create a new app for the new folder to be created. It only seems to do the check and creation in the Expression shape correctly the first time I deploy and create the application.
How do I get BizTalk to refresh and use the latest appliction update I have deployed and not use the previously deployed app?
I am using the Trial version of BizTalk 2006.

Everytime you redeploy an assembly used by Biztalk you need to restart the host instance. Either from Biztalk Admin console or from Admin Tools-> Services
The Host instance is a running windows service, that will reuse any previously loaded assemblies. The only way to reload a new build of an assembly is to stop and start the host instance

I read that you have to stop and start BizTalk Service BizTalk Group : BizTalkServerApplication service, it worked but do you have to do this everytime you deploy an update?

Yes you have to restart the host instance ervytime you redeploy. There is an option to do this automatically in the Biztalk project properties under Deployment in Visual Studio
