visual web developer software

Hi,

i start learn the software "visual web developer" and i am quit frustrated from tring to run the appliction.

the error that i recive is this :

Error 1 C:\WebSite1\Default.aspx: ASP.NET runtime error: Object reference not set to an instance of an object.

Huh?

Please don't get frustrated and try to solve the problem. The problem is not with Visual Web Developer but with your code. Try to find where that error is occuring and post back with more explaination and possibly code.



Hi,

Based on my understanding, you want to learn develop web application with Visual Web Developer. When you run a web application, you get the error message above. If I have misunderstood you, please feel free to let me know.

The error message "Object reference not set to an instance of an object" indicates that we use a object instance before we create the instance of this object. The null object will raise this runtime error message when we use it.

We candebug the application to detect where the code is wrong. Please check your code to see if the objects are null before use them.

Besides, you can find more information about asp.net by the following link:http://www.asp.net/get-started/

I hope this helps.
