Sql Currency and a textBox

Hi, I am trying to input a value from a textbox into my sql database. The problem is, is the data type in the database is currency. So how do i pass this through? I had tried to use decimal, but this does not work. There is no currency type in C# that I can see. Any ideas? The line of code I am using is
newRow["invCost"] = System.Decimal.Parse(itemTextBox4.ToString());

Is itemTextBox4 the name of the control? If so you need to the text property, itemTextBox4.Text.

Hey, thanks for that. I felt a bit stupid when I saw that I had left out the Text. It works though, so thank you.

How to paste external window to my form?

Hi!
I need to paste window from some external program (let's say it's MS Outlook for example) to one of tabs in my application. Is it possible?
My first tought was to find hWnd using win32api, and then try to manipulate window like this:
System.Windows.Forms.Control c=Control.FromHandle(a);
It works fine, but only for current window and its children, returns null for other windows.
I tought about playing with some security setting but have no idea hot to apply them to application.

In your button_Click event, write this code:

//TODO: replace "thetext" with your own text
this.Text="thetext";

Can one thread see that the other one's dead?

Bog13-Jul-03 19:46

I have two theads in my windows app- the main GUI thread, and a constantly listening worker which runs an infinite while(true) loop.

The problem is, when I quit the app, the worker thread keeps running and sucks up 100% CPU time. So, I have the main gui thread set a bool variable to false when the app's window closes, and then in the loop for the worker, it listens for that and kills itself when it sees that the bool is false.

That's all fine, but my fear is what if the main window of the app gets blown up, and it's "window closing" event never fires? Like, if the main window is closed because it throws some low level error or something. I've seen it happen already.

In that case, the worker thread would never get the signal to die. Is there some other way to make the worker check on the existence of the gui thread?

thanks

On your worker thread, set the IsBackground property to true.

Thanks, it turns out that the worker thread is not my problem after all. My problem is much deeper and more anoying. So much so that I'll make a whole new post about it.

Changing a button

Ok, I have a button, "buttonDeath" with the text, "Automatic", and a groupebox, "groupeBoxCarnage".

"groupeBoxCarnage" is greyed out when the form loads... enabled=false;... ok.

now, when I click on my button, my groupe box becomes un greyed, enabled=true...

now, what I want is... when I click on my button (buttonDeath) it's text will change... from "Automatic" to "Manual".

To do this right now I have...

this.buttonDeath.Text="Manual";

but here's the part that keeps getting me...

I want to click on buttonDeath again, and have his text change back to "Automatic" and also gray out the groupe box "groupeBoxCarnage" again...

how could I do this???

Something like this will do that:

private bool bDeathClicked; // class member variable



private void OnbuttonDeath_Click(object sender, EventArgs e)
{	
   if(bDeathClicked)
   {
      this.buttonDeath.Text = "Manual";
      this.groupeBoxCarnage.Enabled = true;
      bDeathClicked = !bDeathClicked;
   }
   else
   {
      this.buttonDeath.Text = "Automatic";
      this.groupeBoxCarnage.Enabled = false;
      bDeathClicked = !bDeathClicked;
   }
}

You could try playing with the Enabled property of the Button

rich edit component

is there some drag¨drop-on-your-form-like-in-VB component, that allows mildly "rich text editing" (basic text markup, headers, lists, table would be nice...)?

Could be HTML or RichEdit based, don't really care, as long as it integrates nicely...

[edit] complete with toolbar, font selection, common keyboard shortcuts, stc. etc. And, well, HTML would be nicer Wink | ;)

What about the RichTextBox Class[^] which gives you a Windows rich text box control?
