Security.Permissions issue

Question

Thank you in advance. I'm writing some simple EDI processing software for my sales department and I ran into an issue with Permissions. I'm a converted java programmer so this .NET security stuff is greek to me. My application runs fine when its on a local machine obivously cause its fully trusted but as soon as I move it to a network share I get the an error involving FileIO. I disabled the caspol on our dev server but I still get the error. My current FileIO objects are try{ StreamReader sr = new StreamReader(infile) StreamReader sw = new StreamReader(outfile) (some code) } Can anyone help me understand how this PermissionSet thing works well enough so I can get it to read/write files while its on a local share? Thanks again J. Holt

I denial is probably from the user's PC. The trust level is set to low. Here is how you can change the trust so that the user can run the application on the network an access external resources... 1. Go to Start then click Settings and then Control Panel on the user's PC. 2. Select Administrative Tools. 3. Select Microsoft .NET Framework 1.1 Wizards or which ever framework version htey are running. 4. The wizard window should display three options select the Trust an assembly wizard. 5. Decide if the change should be for the computer or just this user then click Next. 6. Browse to the locate of the application and select the assembly (executable file) click Next. 7. Move the slider control up to Full Trust. Remember that your only setting trust for that application and that your not opening the entire network up to the user. Click Next. 8. Click Finish and text the application. Hope this helps! One note though I am finding that eveytime I rebuild the program and place it on the network the user has to re-assign Full trust again. I am getting ready to POST this to the forum and see if there is a way to work around the appearent version issue.
