I'm using VB 2005 and have an Edit - Entry form with Textboxes and several Comboboxes. I populate the Comboboxes with Arraylists as shown below. I populate a datatable with the Employee data from my SQL Server. I assign the BindingSource1.Datasource to my Datatable then add Databindings to the ComboControls. The (Fields.STAFF_MGR_ID.ToString) is from an Enum. When all is complete my textbox fields Bind and move with the MoveNext.. no problem, but the comboboxes display nothing.

I would like to create a button that clears textboxes and comboboxes when it is clicked. For example when 'btnClear' is clicked then txtDate gets cleared (i.e. txtDate is 22/05/2000 then when btnClear is clicked it has nothing in it)
I have already tried txtDate = "" and txtDate = Nothing but an error comes up.

I have an edit Contact Form that pulls data from access and loads it into textboxes and comboboxes. The text is working fine, but I am trying to pull a number from the ddatabase and display that value in a combobox that already has selections in it, so the user can edit it. For example the combo box is filled with 1,000,000 - 60,000,000 and if the number in the database is 2,000,000 I wan the combobox to display 2,000,000 Here is the

I have tried selectedtext, selectedvalue, and selecteditem but none of them work because its a number.

I just started programming in VB.NET 2008 with the Express edition and have been having a blast so far. I thought a fun program to try and make would be an infix to postfix program.
I have five text boxes off to the side of my program that shows what is on the stack as you iterate through the equation. I'm wondering if it's possible to make these textboxes set to display what is at a certain index of a stack.
For example, if I pushed a "(" onto the stack, I would like the top box of my textboxes to update and show a "(". When something else is pushed onto the stack, say a "/", I would like the "(" to be displayed in the second box down, and the "/" to be displayed in the top box now.
On one of my forms i have a datagridview binded to an Access database. It displays only first and last names of my customers in a datagridview.What i want to do now is, when i double-click on one of the customers another form will open and display details for this customer (detailed view - textboxes).
What i have accomplished so far is that when i double-click on a customer in datagridview a form opens with details (linked to the same binding source as datagridview). But the problem is that it always opens the first record even if i dobule-click second or third in datagridview.I don't know how to bind these textboxes with current datagridview position?
this is a subset of a previously posted problem, I have narrowed down my issue and am reposting a question from this thread: [URL] I have apparently confused the compiler by renaming some comboboxes in Visual Basic .net express? (See relevant code below) I think the confusion is in who should handle what, with two routines named with variations of ComboBox1 and one handling the other ( it confuses me just trying to interpret it mentally):
I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.

I have a list of a few 1000 names, which I need to load in several comboboxes. Now I can add them manually in the editor, but then the code would be huge, which is unneeded in my hones opinion. Sure I can add then in a database and load them, but that takes more time then loading a file from the hard-drive.
I'm working on a program in which I have 2 comboboxes and have to be able to add new Items in both of them, now that all no problems at all but as soon as I close the program I loose all my Items. Is it possible to add a code which checks if an Item already exists and if so give a error message and don't add the new Item to the combobox?
I 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.

My problem is when the user makes changes to the data using the data entry form, the report does not reflect those changes. I have to close the entire program and reopen it before the changes take effect on my report. This piece is used to bound the report to the dataset
