View 3 RepliesControl Array Of Datagridview Objects?
Oct 13, 2011Migrating from VB6, a control array of flexgrid objects. Obviously flexgrid is not supported by VB.NET, so DataGridView objects have to be used instead. I tried this alternative to placing them in a list.
I have two DataGridView objects which share a lot of code as well as event handlers. They are named D1 and D2 and many properties, such as column headeders etc., are set at define time. The control array is simulated by passing the "index" and selected grid as parameters in subroutines. For example, the routine to fill the grids, is as follows.

How To Create Timesheet Using DataGridView Control
Mar 17, 2011I am creating a timesheet using a datagridview control, the user must enter the time in the cells for the code to process. The control however converts the data to a string even though the defaultcellstyle.format is "t" for shorttime. I need to get the control to accept time in various formats and covert it to a standard format. If the user enters 8.00 the cell should display 8:00 am, if the user enters 8p the cell should display 8:00 pm.
After entering the data the user clicks a button to process the data, the code checks each entry to ensure it is a date (using IsDate) and performs some calculations based on the times entered by the user. the information is then stored in a table. My problem is the datagridview control converts the cell entries to strings but I need it to retain the datetime format as I get a casting error when I try to use cdate to convert back to date.

VS 2008 - Index Outside Of Array Runtime Error
Apr 18, 2009I just recently started getting an index out of bounds error on one of my arrays at runtime. I was not having this issue previously. It only seems to happen when several items are added to a listbox.
Here is my declaration and code.
Dim ClientActiveMedProbs(frmmain.lstActiveMedProbs.Items.Count) As String
'store all active medical problem information in an array & build a string
For i As Integer = 0 To frmmain.lstActiveMedProbs.Items.Count - 1
ClientActiveMedProbs(i) = frmmain.lstActiveMedProbs.Items.Item(i).ToString

The actual error message is:
Index was outside the bounds of the array.
