ComboBox In Form - Filling Data Object?
Jun 5, 2011I have a combobox in a form, I want to fill it with names I have stored in a database. I know I have to use the fill command, but I am not sure what code I need to use. I imagine I need to place this code in the form load event, where I wrote my code to connect to the database. Do I need to create a sql fill command, select Names From Users, then execute that command in the combo box object.

Jul 18, 2010Was updating a project and all of a sudden the auto-filling of a WebBrowserControl's Dropdownbox stopped working. Here is the HTML of the Input box:
[Code]....
I think it is the "onkeyup" thing that isn't getting fired properly so the dropdown list isn't updating itself... it was working fine before, and now, with no changes, it just stopped working. can someone take a look at my code and see if they spot anything? EDIT: attached an image of the dropdown box in question. as I type, it does the lookup. (using the onkeyup event). I am setting the value of the dropdown to the five digit code at run-time, trying to trigger the onkeyup event to get it to get the full line, but it won't work.

Reading File Names And Filling A ComboBox?
Sep 15, 2011I tried the code below but unfortunately, all i get is a combobox with U,s,e,r,s, as each line in the items collection and not the filenames of the relevant files.
the DirGetPath("Users") Function below returns my default document and application paths and appends "Users" to the end as the relevant files are stored in that Folder.
All I get is a combo box with the items as U, s,e,r,s (i.e. Users spelled out).
I tried all of the following as alternative methods too:
System.IO.Path.GetExtension()
System.IO.Path.GetFileName()
System.IO.Path.GetFileNameWithoutExtension()

As it stands, I can create one template file, containing the filled template contents using only the first group of placeholders. I am nearly there, just trying to finish the last piece of the jigsaw.

VS 2010 Filling 2 Comboboxes, 1st Determing Data For 2nd?
Mar 27, 2012I am having difficulty trying to fill two different comboboxes (cbo) with data from a database. More accurately, the 1st cbo gets filled correctly, but when I attempt to do something similar with the second, I'm getting an error about not being able to use the & Operator in my SQL string (Operator is not defined for string and DataRowView types). So evidently the SelectValue from my combobox isn't acting the way I expect.
The overall goal of what I am attempting to do is to fill two cbo's, one with a list of contracts and a second as a list of parts given the selected contract from the first cbo. There are 3 tables in the database that I am drawing the data from: the "contract" table, the "parts" table, and a bridge table called "partList" that has foreign keys pointing to the two other tables. The first cbo is a basic query to the "contract" table using "ContractName" as the display member and "idContract" as the value member. The 2nd cbo I would like to display the name of the part from the "parts" table but use the id of the part from the "partsList" table, and to further filter this list based on what contract was selected.
I am writing the code in VB.Net from VS 2010, storing the data in a MySQL DB, and using a DBFactory to create all the components from ".GetFactory(MySql.Data.MySqlClient)"Below is the code that has the two places I am attempting to fill the two cbo's. Also if there is a better way to handle this, please let me know.
