Hi
when I run my application for some users it gives me the following message
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

any body help...

Thanks sir.. I followed your suggestion and got free by exception..

another request.

I am working on AxMSFlexGridLib as a Girdview, also I have taken a combobox in my application. Now I want to put the data into AxMSFlexGridLib where Id=Combox.
but problem is that I want to set the data where row is focused in AxMSFlexGridLib.

and i did code as:

private void workercombo_SelectedIndexChanged(object sender, EventArgs e)
        {
            try
            {
                if (!this.check)
                {
                    this.check = true;
                }
                else
                {
                    this.combo1.SelectedIndex = this.workercombo.SelectedIndex;
                    this.lblname2.Text = this.combo1.Text;
                    this.combo2.SelectedIndex = this.workercombo.SelectedIndex;
                    for (int i = 1; i                    {
                        for (int j = 1; j < this.flex1.Cols; j++)
                        {
                            if ((this.flex1.get_TextMatrix(i, 5).Length == 0) && ((this.flex1.get_TextMatrix(i, 4).Length > 0) || (this.flex1.get_TextMatrix(i, 8).Length > 0)))
                            {
                                this.flex1.set_TextMatrix(i, 5, Convert.ToString(this.workercombo.Text));
                                this.flex1.set_TextMatrix(i, 6, this.lblname2.Text);
                                this.flex1.set_TextMatrix(i, 7, Convert.ToString(this.combo2.Text));

                                return;
                            }
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message,"Error!");
            }
        }

but this is working in a series one by one from top to bottom while my requirement is to set the data on focused row. or selected row.

hi kanhilal,
yeah! Vulpes said exactly... Application need atleast one record/row for proper execution. So, Just put validation on rowcount=0 do nothing else control.

All I can tell you is that, when you call GetNodeByIndex(0) on a System.Data.RBTree generic object, an exception is occurring because there aren't any rows in the RBTree.

If this error is only occurring for some users, then the RBTree can't have been populated at that stage for those users. I'd put in a test to make sure that there are some rows in the RBTree before you execute the offending code.
