No - a console app does not have a message loop to process messages from the mouse.

Adding a phantom item to a databound combo box?

Furty23-Apr-06 18:33

I have the need to add a phantom "All Selections" item to a databound combo box, but inserting a new item into the data binding source results in source collection also having the "All Selections" item throughout the entire project, which is not desired.

So what's the best practice way of inserting a phantom item into a data bound combo box, so it doesn't mess up the underlying data source?

You can create a class which wraps the actual data source, and exposes an augmented version of the data source with the extra item(s) in the list. Then bind the ComboBox to an instance of the wrapper class.

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...

Try this code:

foreach(Control ctrl in form1.Controls)
{
     if (ctrl is Label)
     {
         console.write(((Label)ctrl).Text);
     }
}

Best regards, Alexey.
