Thats true but I think the OP is asking how to display those in the textbox so that someone understands that it is looking for a date.

Do you mean myBase[^], or what do you mean?
If MyBase is a class of yours that has a Finalze method, then that method is the finalizer of the class. A finalizer is usually only used as a backup for the Dispose method in a class that implements the IDisposable interface.
(Classes in C++ have destructors, and the same syntax is used for finalizers in C#, but finalizing in .NET works differently from destruction in C++, so I prefer the term finalizer to emphasise the difference).
When an object is about to be garbage collected, and it has a finalizer, the object will instead be placed in a queue of objects to be finalized. A background thread will run the Finalize method of each object in turn, and after that the object can be garbage collected.

MyBase refers to the base class that your class inherits from. It's normally used to call methods or set properties, or what have you, that are implemented in the base class.
Public Class MyTextBoxClass
Inherits System.Windows.Forms.TextBox
...
' Sets the location of the top left corner of our TextBox
MyBase.Location = New Point(40,20)
Also, there are no such things as destructors in the .NET Framework. Dispose and Finalize just gives an object it's last chance to clean up any resources it has to before the GC collects the object.

What do you expect this xml file to 'do' ? Xml doesn't 'do' anything, it's just a representation of data.

file is a string, as defined previously, that contains the name of the file. The method you call expects an integer, the ordinal position of the column you are trying to retrieve.
I don't know what, exactly, you are trying to achieve at this point. What do you think should be happening on this line?

Ok what to do???? pls tel me the error...

I've told you the error.
The error is you have put a string where an int was expected.

You need to tell me what you EXPECT the code to do. I do not know what you are tying to do. Until you tell me what you are trying to do I cannot help you.

You have to create a Bitmap with form's size. Then, create a new Graphics from the Bitmap, and then call the "CopyFromScreen" method of the Graphics object. Here you have c# sample code... You only have to translate to vs basic.
Bitmap oCaptura = new Bitmap(this.Width, this.Height);
Graphics oGfx = Graphics.FromImage((Image)oCaptura);
oGfx.CopyFromScreen(...)

Hey all,
I have a form in which i want the user to be able to delete all there private data i.e. cookies, recent files, temp Internet files and stuff like that. What is the command to delete all the files in a certain folder and how would i make it recognise which account they are running the program and delete only there files.
Thank You

Just deleting the files in the user Temporary Internet Files folder, and subfolders, doesn't work. You have to call into the Win32 API to clear the browser history cache.
If you just want a utility, you can save yourself the time of writing something yourself by checking into something that's prewritten for you, like this[^].
