I guess posting some code would be a good start.
I also have an article on all the reasons that that namespace sucks, you should read it

OK, that's how it works. Have you considered using the Windows Media Player control instead ? That is just plain better.
Odds are you've just made a silly mistake ( like the control is not visible ), but I'd really suggest WMP is better, overall.

Hi
I am kinda new to vb.net and I am having problems with code that works when it suits it. The code is meant to check if data has been entered into the text boxes. For some unknown reason it works on one form but the same code copied and pasted does not work on a different form.
this the code.
'This checks the textboxes to see if the data entered is correct
Dim ctrlx As Control
For Each ctrlx In Controls
If TypeOf ctrlx Is TextBox Then
If ctrlx.Text = "" Then
ctrlx.Focus()
MessageBox.Show("Please enter the required data", "Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
Exit Sub
End If
End If
Next
I hope u will be able to help me,

What is not working? Be a little more descriptive.

Hi Paul
The code is meant to check all the text boxes on a form. If a blank field is found the user a msgbox is displayed asking the user to enter the required information. Similarly the code can also be used to check each text box to see if the data entered is of the correct type.
On the first form code identifies all the textboxes that have been left blank. On the 2nd form this same code does not work. When I click the button, nothing happens, the blank textboxes are not identified and no error messagebox is displayed, of which when I do the same thing on the first form the program is able to pick up all the blank fields.

Is this code being called in both forms ? Do you have breakpoints so you can see what is going on ?

Like Christian said, is it being called by both? Have you tied in any event procedures to call it?

This is almost certainly not true.
Most likely, on one form you have an event set up to call this method, and on the other, you do not.

Hi,
Do you host your textboxes into sub-containers (e.g. Groupbox, Panel, ...) If yes, then you must iterate over the controls of sub-containers.
Hope this helps

Hi
Thanks for helping. I do have a group box on the form. I still got a bit of a qn? What do u mean by iterate over the controls of the form, How could I go about this?
Thanks again.

You cannot compare the type of control with TextBox Class. The control has to be compared with the type of TextBox.
Possibly the the code snippet will resolve your issue
For Each ctrl As Control In Me.Controls
If ctrl.GetType() Is GetType(TextBox) Then
If ctrl.Text="" Then
MessageBox.Show("Message",MessageBoxButtons.OK,MessageBoxIcon.Exclamation)
ctrl.Focus()
End IF
End If
Next

Please only post the part of the code that is having trouble. You posted more than necessary.

What on earth are FileOpen, FilePut, etc ? Nasty VB6 legacy methods, or methods you wrote ?

I vaguely remember seeing something hideous like that in the early VB days.

Sounds like you should be buying a book, working through it, then moving on to the articles on this site. No-one can post anything that is likely to help you at this point, in a forum reply.
