I am creating the items in a combobox in my code behind. I am setting the display member and the value member. When the user makes a selection from the combo box, I need to get the value of the selected item. I have written some code, but when I step through it, it says that the selectedvalue is Nothing.
Here is the code where I am creating the items in the combo box:
Do While drReader.Read
cboTheater.Items.Add(drReader("TheaterDesc"))
cboTheater.ValueMember = CStr(drReader("TheaterID"))
cboTheater.DisplayMember = CStr(drReader("TheaterDesc"))
Loop
In the selected index change event for the combo box, I am doing the following:
Dim strTheater As String
strTheater = CStr(cboTheater.SelectedValue)
When I step thru the code, strTheater is Nothing

I have a form on which the user selects a file using an openFileDialog. The selected filepath is then processed, which may take 10-20 seconds before the user is presented with the results.I'm finding that the once the user selects the file (clicking the OK button on the openFileDialog), the openFileDialog remains open until all of the processing going on in the background is completed. Once the processing has finished the openFileDialog disappears and the results are shown.The problem is that whilst the openFileDialog remains open on screen, it is not apparent to the user that anything is happening in the background. I do actually have a textbox which updates the user with messages showing the progress. However the openFileDialog hides the messages until it closes, essentially making the progress messages useless.What I'm trying to do is have the openFileDialog close immediately that the user selects a file. Then the processing can continue without the openFileDialog obscuring my form.

I'm in the process of adapting a current program that I've created to automate it. **Current State***User selects an excel file and the contents are loaded into a DataGrid User can select which environment to run their query against (stage/prod) Program completes processing and updates datagrid with new values User can export datagrid to excel What I'd like to do is centralize the program on one computer and have it monitor a network folder for creation of a specific file type (*.xls or *.xlsx). If one of these is created in that folder then I want to add that file to a queue for processing. Once done processing I want to send the results as an attachment to an email to the user that created the file. After a file is processed I would like to remove it from that folder as well (into a diff folder of completed items).

I'm using Microsoft Visual Basic 2008 Express Edition. I have a Folder Dialog Browser added in my form and I call it when the user presses a button. The folder path string is stored in a string variable and displayed as text in a text box. (maybe I should use a combo box)
My question is: If the user inputs by hand a non existent path, how do I return an error message, stop the file creation into the invalid path, and return to my main form?

Here's what I'm attempting: The user browses for and opens a dbf file. The user is presented with a checkedlistbox which shows the column headers. The user then selects the columns they wish to run a report on. ex. total # of cells not empty, longest cell length, etc.
I'm to the point of populating the checkedlistbox with all of the columns shown but I'm unsure if the users selections are actually linked to my data and if they are how I go about isolating said selections for the reports. I have a feeling that my approach to populating the checkedlistbox is not the proper way for what I'm trying to accomplish.
Here is the code
Public Sub btnGetFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGetFile.Click
Dim fileLookUp As New OpenFileDialog

I have a single instance app that is working fine except for this strange (to me) issue.
The user could double click on FileA and my app opens and displays the file contents (the path of FileA has been passed as a parameter) No problem there. The problem is that if the user then double clicks on FileB and I read the parameter it still contains the path to FileA. What trick am i missing here?
(If i add a debug line that forces the code to be FileB's path the the app works correctly in terms of opening a new tab, reading the contents etc.) (vb.net 2010)

I have an OpenFileDialog. I want the program to copy the file that the user selects to my "temp" folder. If the user doesn't select any file, then it doesn't copy any thing. Here is my code:
Dim Temp As String = "Temp"
If Not Form6.OpenFileDialog12.FileName = "" Then
System.IO.File.Copy(Form6.OpenFileDialog12.FileName, Temp & System.IO.Path.GetFileName(Form6.OpenFileDialog12.FileName))
End If
But it doesn't copy any of my files over that are loaded in the OpenFileDialog.

In my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2
I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also. For instance, on Row1, if comboBox1 = A, combox2 = B
Then on Row2, if comBox1 = Y, comboBox2 = Z
However, when I change Row1, Row2 is also changed to reflect what was chosen in Row1. Is there a way I can tailor it to each specific row?

I have a combo box and use the SelectedIndexChanged event. I noticed when I assign a value to the combo box that this event fires even though the user does not click on the control. Can you tell me how to test for when the user clicks on it and actually selects a value from it?

I have a simple web for that has a dropdown list and a button on the form.The dropdown list is bound to a table in my database and holds three values with idents between 1 and 3 (Weekly,Monthly, Please Select).I have set my datasource to pull back item 3 (Please Select) as the first item in the dropdown list to prompt the user to select an option. Items 1 & 2 have data assigned to them and this pulls back the relevent data for these options.
Here is my problem. I need to hide my button when the page loads until the user selects item 1 or 2 and would like the button to be hidden of option 3 is selected. I have tried to complete this in my page load event and the code for the dropdown list but i cannot seem to get this to work.
If IsNumeric(DropDownList1.SelectedValue) = 3 Then
btnAddAgendaTemplate.Visible = False

I'm trying to create a for loop that will display the values (favorite programming languages) a user selects for a listbox.
So far I have this:
Dim selectedLanguages As String = ""
For intLoopIndex As Integer = 0 To languageListBox.Items.Count - 1
[code]....
So far, no matter how many items they select it will display a comma even if only one item is selected, example "C#,"However this is what I need it to do:
1. If the user selects one programming language than it should just printout the selected course with a period right after it. Example: C#.
2. If the user selects two languages it needs to have the text "and" between them followed by a period. Example: VisualBasic.Net and C#.
3. If the user selects three or more languages it needs to seperate them like this for example (again with a period at the end): VisualBasic.Net, C#, and Asp.net.

It's probably the most basic of things, but all I can find is how to launch a program, and not with the interactions I desire. Any tips as to the terms to use to search for answers, or links to topics regarding questions similar to mine, would be very appreciated. I have a wealth of info to read through, but I could use your knowledge to save myself time.Here is what I am trying to do:
Use a Button (A) to Launch a Prompt where User Selects Directory Path to an executable Program. The Selection is to be Persistent after the initial selection (saved in a settings file i assume?), and the Selected Path (or just "programname.exe") is to be Displayed in a Text Field (B). Launch Selected and Indicated Program via a Launch Button (C)
