Child Tries To Delete A Character From A Previous Field?
May 3, 2010I am making a small and very simple game that is ment to help children learn to recognise letters. I have come to a stop as I have 3 text fields. When something is entered into the first field, the program will set focus to the next text field. The problem is when the child tries to delete a character from a previous field as the focus is already set to the next text field. I want it to delete the character from the previous field when the backspace bar is hit. Any suggestion how this might be done?

DataRow Collection - Update Requires Valid Delete Command?
May 1, 2010I'm going through a book which is teaching me some basic coding principles of the language. The current section is detailing how to set up a master child form using two tables linked with a foreign key. The master table is displayed as a number of text boxes, and below is a grid with the child table which shows related records to whatever master record you happen to be checking out. At the top of the screen are the default navigation controls that are added with the grid. The master table is named Person and the child table Book. They are linked using a foreign key and have cascade set up on them.
The book informed me of the code required under the save icon on the navigation control so that when it is clicked both tables will be updated as required. It is as follows:
If Validate() Then
'Make sure editing has completed on both master and child tables
Me.BookBindingSource.EndEdit()
Me.PersonBindingSource.EndEdit()
[Code] .....
I have double checked that the code matches that shown, so this should in theory work fine. But if I manually delete a record from the Book (child table) grid and then click the Save icon on the navigation bar it comes up with the error "Update Requires A Valid DeleteCommand when passed DataRow collection with deleted rows".
Why changes made are not permanently saved to the database? I gather that it's using a "copy" of the data in the database but how do I get the code/form to make changes to the actual underlying database records as well as just the copy? I find this system very unusual, if someone deletes a record in the application why would anyone want this to be just done temporarily?
