The upper 128 characters are not standardized, although many well established character sets use all 256 characters. Unicode characters are a superset of the ASCII character set.They are represented by two bytes, which allows a maximum of 65,536 characters.In this case, I think the simplest solution is to validate these textboxes in the Save button's Click event handler, instead of validating the textboxes in their Validating event handler. None" above prevents the dialog box from closing & returning Dialog Result. Here's my code | | Private Sub Save() | For each c as control in Me. Of course, you could include the code of validating these textboxes in a function and call this function in the Save button's Click event handler. If you have anything unclear, please feel free to let me know. None Exit For End If End If Next End Sub NOTE: This loop probably should be recursive to get controls within container controls, within other container controls... Here's my code Private Sub Save() For each c as control in Me. Click If Not Validate Children() Then Dialog Result = Windows. In this section, you will see examples of events in use.Keyboard events provide access to this type of functionality.The three events listed in Table 4-5 are raised when the user presses a key on the keyboard.

The only way I've found todo this is to cycle through every control and call it's . This is clunky though because you can see a flash in each text box as it'sbeing validated. Select() End if Next c End Sub Each control has code in their Control_Validating event that fires off anerrorprovider. With VS 2005 you can use something like: Private Sub button Accept_Click(By Val sender As Object, By Val e As Event Args) Handles button Accept. None Return End If End Sub Where you have Auto Validate set on the form itself: Me.

Unicode and ASCII Characters Each character in the American Standards Committee for Information Interchange (ASCII) character set is represented by a single byte (8 bits) of data, representing 256 characters.

The first 128 characters (represented by 7 bits) are standardized and usually referred to as low-order ASCII characters.

I have a windows form that I want to force validation on controls (text boxes) when the user clicks a "Save" button. Select() End if Next c End Sub Each control has code in their Control_Validating event that fires off an errorprovider. Here's my code Private Sub Save() For each c as control in Me. Try using the Lock Window Update API call to prevent the objects from being updated while you cycle through the list. If you hit an error, or you successfully reach the end of the list, a call to Lock Window Update(0&) releases the lock.

The only way I've found to do this is to cycle through every control and call it's . This is clunky though because you can see a flash in each text box as it's being validated. Select() End if Next c End Sub Each control has code in their Control_Validating event that fires off an errorprovider. Here's my code Private Sub Save() For each c as control in Me. Since only one lock can be in place at any one time you would want to lock the whole form during the validation phase.

Here's my code Private Sub Save() For each c as control in Me. (It doesn't cost anything extra.) Private Declare Function Lock Window Update Lib "user32" (By Val hwnd As Long) As Long Lock Window Update(Me.
