Hi..
The part of the SQL statement that you've sent seems correct...You need to get a specific error to understand what exactly is going wrong..
You can do one thing, use Try-Catch to handle the exception.
Try
//code
Catch ex as OleDbException'
MessageBox.Show(ex.Message)
End Try

ok tnx, ill try it.

You should use parameterized qzeries to increase security of your code as well as readibility. Take a look at the following article here on CP: SQL Injection Attacks and Some Tips on How to Prevent Them[^]

Use client-side code to validate the data entered..a javascript function will work fine...

Hello Praveen,
You can create your inherted TextBox and use this code:
protected override void OnKeyPress(KeyPressEventArgs e)
{
string _allowedkeychars = "1234567890";
if (_allowedkeychars.IndexOf(e.KeyChar) < 0)
{
e.Handled = true;
return;
}
// Youre code.....
base.OnKeyPress (e);
}
All the best,
Martin

Hi,
How do I get the text to wrap after the focus leaves a datagrid cell? When the cell is in focus, it wraps the text, when it looses the focus, it displays the data in a single line. How do i retain the word wrap when the focus is to some other cell in the datagrid.
Thanks in advance for any suggestion or help

Hi Friends,
I am having an windows application created using C#. Its having a MDI form and many child forms. What i have to do is when i click a menu from the MDI window i get a form having a datagrid and many other calculations done and at the end of the page i have a print button. I want to print that entire page when i click the print button. I got a code from google but what it does is capture the screen and then prints. since it captures only what we can see in the screen i dont get the rest of the content which is visible only if i scroll down the window. i want the entire page to be printed.
Thank u,
Vips
