The second step is to show your intent in the code file that you will be
using types from the namespace(s) in the said dll.
In this case this means the ComponentModel namespace.
Try inserting the following line at the top of your file:
using System.ComponentModel;
or in VB:
Imports System.ComponentModel
Let me know if you are still having problems and I do recommend downloading
the sample I pointed out (you would have found this on your own then

Carsten Marx said:ok, my fault....
now here my code:
// Call this method in form's ctor
private void InitBW()
{
mBW = new BackgroundWorker(this);
mBW.RunWorkerCompleted += new
RunWorkerCompletedEventHandler(mBW_RunWorkerCompleted);
mBW.ProgressChanged += new
ProgressChangedEventHandler(mBW_ProgressChanged);
mBW.DoWork += new DoWorkEventHandler(mBW_DoWork);
mBW.WorkerReportsProgress = true;
mBW.WorkerSupportsCancellation = true;
}
// Completion event
private void mBW_RunWorkerCompleted(object sender,
RunWorkerCompletedEventArgs e)
{
this.pgBar.Hide();
}
// Progress event
private void mBW_ProgressChanged(object sender, ProgressChangedEventArgs
e)
{
this.pgBar.BringToFront();
this.pgBar.Value = e.ProgressPercentage;
}
// On worker thread! Only method with real logic
private void mBW_DoWork(object sender, DoWorkEventArgs e)
{
this.refreshView();
}
/// <summary>
/// manage the click on the TYP button
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void bTYP_Click(object sender, EventArgs e)
{
this.activeCategory = "TYP";
this.resetActiveCategory();
this.BackColor = Preferences.COLOR_CATEGORY_TYP;
this.refreshView();
}
the method refreshView handles some stuff to load data and managa the
gui...
whats wrong?

Daniel Moth said:Carsten, you will have to always provide details on the errors you are
seeing. Simply asking "what is wrong" does not give any information. In
the code you posted, you left out the most important method:
thisRefreshView
Now, the blog entry you downloaded the BW from, had links that describe
each method. Please read them. In particular from my blog post read this
part:
4a. It raises the event. In your DoWorkEventHandler method do your
background stuff (without touching GUI of course)
The key being "without touching the GUI of course". So, in your mBW_DoWork
method do not touch UI elements (you can do that from any other method you
like).
Feel free to post back with specifics.

http://www.danielmoth.com/Blog/2004/12/backgroundworker-for-cf-10.html
after adding the dll to my Projekt.
But it's not working... Whats wrong?

..sorry german..
In English it should be:
The type or namespace "BackgroundWorker" could not be found....
regards carsten
btw: the dll is added to the project...
That is what I mean by "in your mBW_DoWork method do not touch UI elements"
He doesn't need to use Invoke; that is one of the advantages of the
)Shouldn't touch the UI from anything mBW_DoWork calls either since it's
still the same worker thread context. He *must* use Invoke to touch the
UI, and I'd bet dollars to donuts that's the probelm.

He doesn't need to use Invoke; that is one of the advantages of the
BackgroundWorker. Anytime he wants to touch the GUI he calls
mBW.ReportProgress from within the mBW_DoWork method. (it took me a while
to get used not being in control of it but believe me this component is
beautiful
It is probably worth noting (for the benefit of the archives if nothing
