Im using a mySQL DB and some obj that does the connect to it (called DBOperation).
in the DBOperation() constructor I do my connecting to the DB
myDb = new OleDbConnection(myConnectionString);
myDb.Open();
then i got some funtions for reading/writing..
in my ~DBOperation() destructor I call a Disconnect() fkt where i do:
myDB.Close
but while Calling that i get a Exception : "Handle is not initialized"
here is the full Exception Text:
Exception: Handle is not initialized.
at System.WeakReference.get_Target()
at System.Data.Common.WeakReferenceCollection.Close(Boolean flag)
at System.Data.OleDb.OleDbConnection.CloseReferences(Boolean canceling)
at System.Data.OleDb.OleDbConnection.DisposeManaged()
at System.Data.OleDb.OleDbConnection.Close()
at DBTest.DBOperation.Disconnect()
at DBTest.DBOperation.Finalize()
Can anyone tell me why this happens ... any Help would be great
Yours LaMagra

Are you sure your destructor is called?
It sounds like that on yoo, but the destructors in C# is not the same as C++' destructors. It's not a guarantee that C# destructors are called when an object is destroyed. I don't knwo why (have forgot it )
But this maybe wasn't big help to you, sorry!

This code doesn't work for me:
String str = this.textBox1.Text;
String newStr = str.Trim();
MessageBox.Show(newStr);
The MessageBox that appears contain the string WITH all white spaces!!!

Trim only removes leading and trailing whitespace. It doesnt remove the spaces between words etc. Is that what you mean?

Well I can compile it... but I missunderstod the use of Trim(). I thought it was suppose to remove all white spaces in the string!

I think what you're looking for is Replace.
<br />
String str = this.textBox1.Text;<br />
String newStr = str.Replace(" ", "");<br />
MessageBox.Show(newStr);<br />

Quote frpm MSDN ( I suggest you use it )
String.Trim Method
Removes all occurrences of a set of specified characters from the beginning and end of this instance.
Overload List
Removes all occurrences of white space characters from the beginning and end of this instance.
<br />
public string Trim();<br />
Removes all occurrences of a set of characters specified in a Unicode character array from the beginning and end of this instance.
<br />
public string Trim(params char[]);<br />
IOW
<br />
String str = this.textBox1.Text;<br />
String newStr = str.Trim(' ');
MessageBox.Show(newStr);<br />
Hope this helps

Is there anything in C#.that is similar to Control ID's in MFC ?

For what purpose? Without knowing what you wish to do its hard to know if an alternative exists.

If you don't want to write in C#, then why do you bother

As James said, it's hard to suggest something without knowing what you are trying to achieve, but perhaps you are looking for the Control.Name Property

In my opinion P/Invoke is ugly and I recommend that you use MC++ and IJW.

I actually meant that you can use MC++ instead of C#.
Basically if you don't have GUI-intensive work you can use MC++.
Right now they don't have a form designer for MC++. When that comes out you can use MC++ for all your .NET coding. That way you can use your old MFC/ATL code as well as new managed code
