I'm using an array to populate a datagrid. I want a password protected button to be able to clear the data from the grid. I thought this would be fairly easy but so far it's not working. The following code doesn't generate any errors but the array still has data in it.
If txtPassword.Text = "bucswin" Then
Array.Clear(DataGridValues, 6, 23)
frmMain.DG1.Refresh()

I'm trying to export the content of a data grid to an Excel file. But here is my problem:
1. If I use a Data Grid which was set to allow Adding and Editing of columns ( this appeared the first time I add the control to the form) , the resulting excel file will show all the content of the data grid, except for the Headers ( Column names) .
2. If I use a Data grid which was set to disabled adding and editing of columns, the resulting excel file is lacking the bottom-most row of the data grid content. The Headers are also not included.
I cannot choose Option 1, since the data grid must not be editable by the user. I cannot choose option 2 since the last row is being omitted. Another thing is that the Column Names ( the data are coming from a MS Access File) are not added into the Excel File for both Option 1 and 2.
Here is the code I'm using. I found it from the net and tried changing the values of i and j but still I can't get the result I wanted.
For i = 0 To dgreport3.RowCount - 2
For j = 0 To dgreport3.ColumnCount - 1
xlWorkSheet.Cells(i + 1, j + 1) = _
dgreport3(j, i).Value.ToString()
Next

I am creating a program that make a person select different options and in other boxes it will populate the choice the person makes. Example is the program is fora car wash and if you choose standard or deluxe it will show in the other boxes what comes with that package.I got the program to work except when going to select a different option it still keeps the old info and displays the new info as well. I tried like at the bottom of the procedure Exteriorlist.Items.clear() and it would clear and never display the info. I am still working on the project I am trying to get the print option working properly I am just needing help in figuring out how to clear the info when I select a different package.
Public Class CarWash7
Const EXTERIOR1_String As String = "Hand Wash"
Const EXTERIOR2_String As String = "Hand Wax"

I am doing a school project and have created a small program that allows the user to create a binary search tree and then visually displays it on the screen as a familiar tree structure, how the addition, deletion of nodes in the tree works along with many other things such as different tree traversals. I currently using a large panel on the main form and then adding user controls containing a textbox that displays imputed values,then using the panels paint event I draw a line between the user controls, this works fine however for deletion of a node I need to clear the main panel of the nodes that will change and add them to the panel again or just clear the hole panel and redraw the whole tree
