You can do it like this:
private void Enter_Control(object sender, System.EventArgs e)
{
if (sender is TextBox)
{
((TextBox)sender).BackColor = Color.Blue;
}
}

Hi Giorgi,
I had to break the discussion yesterday ...
My code should only test that I have got the right index of the selected control and set the backcolor in this "long way" as test that it works. But the problem already exists, that I don't get an index != -1. This is main funcion of my method
int index = this.Controls.IndexOf((TextBox)sender);
tnx Frank

Is the textbox on the form itself or is it on the panel or groupbbox or any other container? If yes, then instead of this.Controls you should have the container that contains your textbox.

Oh yes,
that's the problem.
Due to the hierarchical structure of my Form each control is a container of controls. I tested my method and it works, for one container, but it doesn't help me with the problem.
my intention was to reference a control by its name (as a string) independant of the location of the control. But the index is not unique and the prerequisite is the known of the hierarchical structure of my form. Changing the form would change the indices.
Isn't there an other way ?

Hi guys,
at the moment I try to migrate a very very simple VS2005 web service example to VS2008. In my scenario I only call a service with two parameters so get the sum of both. In VS2005 it is working like this
C#-Code:
proxy.Credentials = new NetworkCredential (txtUsername.Text, txtPassword.Text);
Double result = proxy.ZAdd(1, 2);
But I cannot use this code in VS2008.
Do you have any solution to pass simple http Authentification credentials?
I appreciate any comment!

Hallo.
Either I am a noob, or something strange is going on .
I have got an ASP.net webform , on this form I have a object datasource ( which is linked to my class).
When I add a form view to the form and link it to my object datasource the template is not generated for me. I need to manually build the template. It is if the formview does not see the objectdatasources select,insert etc commands. The class I am linking to, does work.
please help, i think somewhere I am missing a property or something.
kind regards

Call Dispose when you finish with a bitmap to clean up it's memory usage.

Did you read Christian's reply? Are you disposing your bitmaps?
Memory is managed by the framework - you can't expect the memory use
to go back to what it was before you create an object.

Create a thread in the service that waits until the specified time every day, and the performs its processing.
