You're going to have to be more specific than that. There's hundreds and hundreds of techniques, but what you do depends on how you've written your code and what your code is supposed to be doing. There's just no way to answer this question with the information you've given.
If your app is just consuming memory until the system runs out, then you've got a problem where your not releasing resources properly, like calling Dispose() on objects when you're done with them.

YOu'd be better off asking this in the ASP.NET forum. I think it has something to do with using Server.MapPath to generat the path to the report you want, but I don't know for sure.

Hi,
How to acces DB2 from .Net? what name space we have to use.
Give me sample code for connection.
Thanks........
|
|
|
|
|
You'd be using the System.Data.OleDb if you're not using one supplied by IBM. You can get connection string examples from ConnectionStrings.com[^]

Hi,
How to place a comobox in DataGrid In VB.Net
Thanks........
|
|
|
|
|
You're question is a bit vague. What do you want this combobox to do? Is this box going to be bound to a datasource so you can pick values from a table? Are you supplying your own values, seperate from a database?

You really want some articles on getting started with ADO.Net I just did a quick google on "getting started with ado.net vb" and came back with a load of what looked like suitable articles.
If you're having problems with the connection string check out this site:
http://www.connectionstrings.com/[^]
Hope this helps

Without seeing any of the code that's doing this, it's impossible to tell you what you did wrong. My first guess would be timezone problems, but since we don't know anything about your code or the databases involved, there's really nothing we can tell you.

Hi Members,
I am working on a Desktop/Windows Application. Can anybody help me that how can I stop displaying error messages on webBrowser control when an error occured in displaying page.
Thanks in advance
Regards

You can't stop them from popping up. At least not without modifying the options for Internet Explorer. The WebBrowser control is actualy an IE component that uses all the same settings as it's Blue E counterpart.
Changing system settings is NOT recommended to get the functionality you want.
