I have 12 Boolean values in an array. Each of these values represent a CheckBox in my application. I want my program to output a string, based on each value not selected. Each of these values will have a predetermined string that is different from the CheckBox's caption and will be joined to create a final string. I want to generate all the possible combinations for when there are 1, 2, 3, 4 and so on up to 12 of these options at once. I can better explain my problem through the repetitiveness of the code below.

Above event gives me the index,when i select the tab.
The first would be, how would I go about making each index in a list box an integer or decimal value? For example, If I wanted the 1st (or 0) index to = 300 and the next one (1) = 400. The next question that I have is that, if I had two or more list boxes with each index as a certain value as listed above, how would I go about adding up the total for each index that is selected?
View 10 RepliesI need a way of converting the listbox.selectedindex into hex and then writing it to a file(The writing is done using PackageIO.writer). The weird thing is the code i use works for most of it but on some of the writes and conversions it just converts the selectedindex to 00 when its not.
Dim Writer As New PackageIO.Writer(Filepath, Endian.Little)
Writer.Position = &HE24A
Writer.WriteUInt16(Convert.ToByte(ListBox3.SelectedIndex))

I have a DataGridView containing a large number of columns. I want the users to be able to select multiple columns and then select a menu item to hide the selected columns. For example a user might selected columns 5 through 10 and I want the program to hide those columns. I know how to hide columns, one at a time. I can get the count of selected columns but I have not figured out how to get the index to the left-most selected column. Trial and error is such a slow process.
Considering the huge number of options offered by the DataGridView tool, it would be nice if this forum had a special category for the DataGridView (common to VB and C#).
Finally I got the desired results but it took a lot of coding, looping through the selected cells to find the one with the lowest column index, then a second loop to count previously-hidden columns, then a third loop for hiding the selected columns, stepping past previously-hidden columns and declining to hide frozen columns.

So say I have a listbox, and a treeview. I select(using multiselectextended) a bunch of items in the listbox, I then press a button and it sends those selected items to a teeview node and removed them from the listbox... I then modify the items, add more items, etc..after I'm done modifying them, how could I send the items from the treeview back to theyre original position in the listbox?

This following code works correctly

m_rFlight.Layout = m_rFlight.Layout + "</G3Grid:Spots>" 'add closing tag
What's going on here, what's the reason the first example isnt working and the second is?
The gvwSpots.LayoutToString() function returns a string.

I am using vb 2008, DataBound Controls and typed dataset. My form is having Group Box (initially hidden) and some text box, combobox controls for Data Entry, and the code is
bsSales.AddNew()
txtCreditDays.Text = 20
dtDueDate.Value = dtSalesDate.Value.AddDays(txtCreditDays.Text)
cboGodown.SelectedIndex = 0 '
Default
gBox.Visible = True
dtSalesDate.Focus()
I have set the combo box to select the 1st record in the list however, when the next Statement that is "gBox.Visible=True" is executed, the Combo Box is again set to -1 position. Why is it?
I need to develop a function called SetComboBox that accepts the category(ies) in the ComboBox as a string and returns an integer indicating the index position of the category in the ComboBox. The function is supposed to set the category in the ComboBox Selected Index property to match the string category stored in a database for an inventory item.
