Binding Textbox Issue

Hi,
I have textboxes that are Databinding to a DataTable.
I save the values of the textboxes to an Access db.

I have a textbox that is bound with a db column that is a Long Integer.
If I change the number in the textbox to a new number, and update it works ok. If I clear the number in the textbox in the hopes to set the field to DBNull, then the textbox reverts back to the original bound value.

I'm not able to:
if (txb_Number.Text == "")
{
//this never occurs because the textbox reverts to the original bound Long Integer value
code to update db with a DBNull value
}
I can only change the bound data if a new number is used. A blank textbox (or letters entered) only reverts back to the origninal value. I want to update the field to DBNull if the textbox is empty.

Hi all,

How can I write a hook to detect screen updates using C#?

What I'm trying to get is how to use SetWindowsHookEx to grab all paint messages that occur on-screen, so that I can then grab the update rectangle.

Thanks in advance,
Razi

If you are referring to a Label control you can set its Text property to what ever string you want.

You can draw what ever you want also as GDI is wrapped up in the System.Drawing[^] namespace

Hi, how I can acces properties of component I created:

I create 2 label in my form1, and later I want to get text from each of those labels

I think it should look like this

foreach(Label l in Form1.label)
{
console.write(l.text);
}

but I`m wrong...

     if (ctrl is Label)
     {
         console.write(((Label)ctrl).Text);
     }
}

Hi everyone,

I have a problem re: DataBindings. I binded a textbox with a database in which I would like to show the date in it, but unfortunately I can't remove the time, so that in the textbox the date only is shown. How can I do it? The following is the code I used for databinding.

this.txtDOB.DataBindings.Add("Text", DBHandler.DS, "UserLogInsteacher.DateOfBirth");

Thanks a lot!!

The Add call returns a Binding[^] object which has a Format[^] event. Use it to format your data.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
