merlynml,
Did you try the following?

I hope that helps.

When I try to handle MyBase.Click, it is suppose to handle all clicks done on all controls + form right? If not, what to use?
But the problem seems to be that I cannot compare the sender to see what kind of object type I'm dealing with... sender.GetType() seems worthless and something irrelevant, and I have tried different Ifs, like:
If sender Is CType(sender, Panel)
If sender Is Panel
And so on, but it just dont work which is pretty obvious anyways.
Also what if I want to make a Select Case for the sender? How to do this?
I have tried:
Select Case sender
Case Is pnlBack
and different stuffs like that.
Should it be something with CType?
Best Regards,
Hmmkk

It seems like this works to detect the object type,
Dim ControlType As String
ControlType = Microsoft.VisualBasic.Right(sender.GetType.ToString, Len(sender.GetType.ToString) - (InStr(sender.GetType.ToString, "Forms") + 5))
If ControlType = "Panel" Then
but the problem with handling programmically created controls or all controls still remains...=/ MyBase.Click doesn't work...

Hmmkk

MyBase.Click does NOT handle mouse clicks for the form and everything on it. It only handles the mouse clicks for whatever object MyBase is. There is nothing that handles mouse clicks for the form AND everything on it.
You'd have to specially write the code to attach the Click event for all your controls to the single handler that you're writing. See AddHandler for this. But, this is never recommended. There's actually a performance penalty for routing all the forms controls events through a single Click event handler. It makes for very messy code.
But, there are reasons for do it. For instance, a related group of buttons that all do essentially the same thing could have all their Click events routed to a single Click event handler. See the Handles clause for Event Handlers or the AddHandler and RemoveHandler methods.
Your code for determining object type is grossly convoluted. It works much simpler if you just did:
If TypeOf sender Is object Then

My access table has a date field stored as a string. In the select I want to return all records between a beginning and end date on that field. The variables defining starting and ending dates are date type variables.
So I'm trying to convert the table field to a date type in the SQL string. My select is shown below but it does not work when it executes.
The error message is:
"Data type mismatch in criteria expression."
myadapter.SelectCommand = New OleDbCommand("select * from table1 where cdate(ship_date) >= " + date1 + " and cdate(ship_date) <= " + date2, myconnection)
What is wrong?
Thanks for any help provided.

Are you using a strongly-typed DataSet? If so, the problem may be with the DataAdapter getting a string when it expects a date for the ship_date column. Try listing the columns explicitly and casting dates appropriately. You should always list columns explicitly, anyway - it's a best practice.
I'm not really sure if this is the problem, tho. Just figured I'd throw it out there to help out.

Hi,
I have made a program that would monitor a directory and watch for file creation using File System Watcher. On the Changed event i basically transfer the file created and copy to another folder using File.Copy. It works fine with small file (less than 1 MB). But for large file the program throws an exception as follows:
System.IO.IOException: The process cannot access the file "D:\VB.Net Testing\dest\Gil Scott-Heron - Blaxploitation.mp3" because it is being used by another process.
where D:\VB.Net Testing\dest\ is the destination folder.
But when if i triggered the copy using something else like Button_Clicked, it just works fine. I guess the problem is with the File System Watcher.
Any way I can get around with this problem? Pls Help.

No, it's with how your assuming it works.
The Created event fires when the fire is CREATED, not when it's finally full of data and the other app closes it.
Since the other application is still writing to the file, and most probably has an exclusive lock on it, you have to wait until the other process is finished with the file before you can copy it.
To do this, in the Created event, your code has to try to open the file for Exclusive Read (DenyShareAll). If the Open fails, you'll have to wait a couple of seconds, then try again. Keep doing this until the file opens.
When the file finally does open, you can either read the file and copy it yourself, or close the file, then immediately start the File.Copy just like you are now.

Hello! 
When I locked the access datbase with password, I am not able to open it with the connection string defined below. Any idea why I can't open the
database with the password. I am not typing any wrong password.
When I take out this part (JET OLEDB: Database password=456ffa1;) I am able to process my unlocked database.
Public ConnStr As String = "Provider=Microsoft.jet.OleDB.4.0;Data source=" & Application.StartupPath & "\Database\lyrics.mdb;JET OLEDB: Database password=456ffa1;"
Thanks!

I have Oracle DB Table with one of its column (VARCHAR). I read and write to
this data [non-english or English] using VC application then everything
works fine. But if I use a VB application to read the data[non-english] and
write it back to the same palce the content is corrupted.
Any help is appreciated

The problem is solved. It was due to the difference in the way, the Unicode characters are handled by "Oracle Provider for OLE DB" (OraOLEDB.DLL) and "Microsoft OLE DB Provider for Oracle" (msdaora.dll).
Refer : http://support.microsoft.com/kb/q244661/
My vb application was using msdaora.dll while VC++ was using OraOledb.dll !

Noone here is just going to send you stuff. We'll help you with your code, but your responsible for actually putting effort into searching for your solution first.
BTW, there are no OCX controls that will give the you look and feel of Office controls. You actually have to code it. But like I said, Google for it first. There are TONS of examples out there.

Noone is going to look at this post, simply because of it's size. Don't post your entire app, just the relevent code.
