• Visual Studio Team System What is the criteria for running web validation rules?

  I have a web page that references a gif file, however the file is not there. This shows up in the results when I run a web test. If I add a validation rule it appears that the validation rule is not run, however if I add a validation rule where I do not have a missing gif file it appears to be fine. Tom I did not see this. Here is what I did. 1) I have a web site and I recorded a web test against the home page. 2) I renamed one of the gifs 3) Played back the test and verified the test failed because of the missing gif. It did fail 4) Added a validation rule to the request 5) Played test again and this time the request failed and ...Show All

• Visual C# Database connection Dilema

  Hi I am working on an application with two main parts. The first part is the database I am connecting to and the second is an activeX control. I am also using SQL 2005 Express as my database server.

My app has to do a few simple queries and occationally write some information to the database. The dilema comes from the activeX control. The AX connects to a servlet. This servlet must also connect to the same database as my application, but when the servlet attempts a connection it bounces b ...Show All
