View 9 RepliesSelect A ComboBox Item Which Is A Drop Down List
Feb 28, 2011i seem to have a problem when i try to select a ComboBox item which is a drop down list. The ComboBox contains a list of various items where the user can select from a list, the type of query he/she would like to perform on an Access Database. Two of the items in the Drop Down List are "Employee Sales Between Specified Weeks" and the other item is "Employee Sales Between Specified Months" (without quotation). Now in my VB code, i have a really long If/ElseIf Statement which includes all the options the user can select. Additionally, if the user has selected a week query, he/she must select a From Week, a To Week and a Year (for example week 3 to week 5 year 2009). From Week is another combobox (1-53 weeks) and To Week is also another ComboBox (1-53).When the user selects a month query, he/she should select a From Month from a ComboBox (1-12) and a To Month from another ComboBox (1-12) and the year from the same Combobox (e.g 2009).

View 4 RepliesProgrammatically Add A Drop Down List In Asp.net With Specific Pre-selected Item?
Nov 30, 2011I've worked out how to create a DropDownList using the following code: <select id="salesPersonDropList" runat="server"></select> In my .aspx page, then my code behind loops through database output running:

Automatically Selecting An Item From A Drop Down Menu?
Aug 6, 2009I'm trying to automate a form process from a previous employee. One of the things that I have to do to achieve this is select a COM port from a dynamically populated list. I've looked around and the closest thing I could come up with is something like:
.cbbCOMPorts.SelectedItem(1) =
True
While this compiles, the computer does not like this at run-time. It throws an exception out:
"Object variable or With block variable not set."

May 30, 2011I have a List(Of MyObj), and I want to iterate through that list and compare each element to all other elements in the same list, excluding (if possible) the same element. I have a solution that works, but it's slow and uses double For loops. It may possibly have also summoned Cthulhu from his sleep. This below is a sanitized version of what I have:

View 3 RepliesProgram That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List
May 27, 2012I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible.

View 18 RepliesPossible To Make List Box Item Height For Item Depending On Amount Of Lines That Item Contains?
Jan 1, 2012I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.

As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?
