NullReferenceException

[Stelios]

Hi.

I have a problem with an error that i get and mayby domebody can help.
I have a project that which gives a pop-up error when i open the
project with VS.
The error is :"The following Exception has occured.
NullReferenceEx ception:Object reference not set to an instance of an
object".

The strange part of this error is that i receive it immediatly when i
open the project.
After Clicking the OK button, the project compiles and runs with no
problems.

How can i figure out what is this?

Thanks in advance
Stelios

The popup should have a link that shows the stack trace. If not, you
could fire up a new instance of Visual Studio and connect to the first
instance using the debugger, perhaps that will let you find the
exception.

Re: NullReferenceEx ception

If this is your own code, change it to be like the following:

Try
{your code here}
Catch ex as Exception
msgbox(ex.Messa ge & VbCrLf & ex.StackTrace)
End Try

This will give you information on where and what is causing the null
reference.

Re: NullReferenceEx ception

Hi.
Thanks for your comments!.
There is no link in the pop up window. and the problem was that i could
not find out what is the reason for this error, since it was appearing
immediatly when i was opening the solution file.
After having a detailed look at the project objects that i have draged
from the toolbox, I noticed that one dataset icon was disappeared!.
I created a new dataset object again, i set up again all the data
bindings and everything was OK.
I read that there is a problem with VS2003 about items that get
dissapeared and that microsoft has a hot fix for this.

Thanks
