Writing To File And Selecting An Item Using A Dropdown Box?
Mar 27, 2011
My program that I'm creating is a quiz creation tool, based for teachers to create quizzes and then use them to aid with quizzing their students.I've got the whole program working in that you can create quiz, play the quiz and then see how many questions were answers correctly and how many questions their were The problem I'm having is that I don't know how I can save multiple quizzes, for example you can create one quiz, that then saves as a .txt in debug however, when you then create another quiz and click the save file the old quiz details are sitting in the .txt
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim filename As String 'full file/path name for QuizRecords.txt
Dim index As Short 'loop control variable
[code]....
So what I'd like it to do is, when saved create another text file? Or another set of data questions, I have been looking through my Computing projects in Visual Basic . NET book as well as through online but I can't find anything that I understand as such.

My problem is i have two comboboxes, cmbFamily and cmbModel, I have values in cmbFamily: A320, A330 etc And i have a database that has all the available models for these aircraft types, i have got some help on a query so i can fill up cmbModel with all the models of aircraft available, but i only want to display the models related to the family that is selected in the cmbFamily combobox.
The query i have so far is
Query = New OleDb.OleDbCommand("Select Model From Availability", AccessConn)
'AccessConn is my database connection string I would like to have something that views the text in cmbFamily and then looks for all related model entries in the dataset.

Say I have a listbox lb, which I initialize using:
lb.DataSource = wordList \wordList is a list of strings
lb.DataBind()
The listbox is initialized perfectly, and everything that should appear there does.
However, now I select one of items in the listbox with my mouse (coloring it dark blue, in case anyone wondered what I meant in "select"), and perform the following test:

When my application starts, it scans the computers registry for COM ports and adds them in the combo box. The combo box first index is just a blank, and the second is COM1, COM2,...COMn. What I want to do is by default, I want my program to select the first COM port in the combo box, so in this case, COM1.
I know I have to use the PORTNAME property of the serial object, but not sure how I would set that equal to the 2nd index of the combo box.

Our project is to make some simplified POS software, in our case, for a restaurant. The form I am currently working on is where you pick food items and add them to a listbox which will essentially be the order form. I made a database in Access that has food-item info and linked it to the VB project.url...My combobox narrows down the food items according to what category is selected, i.e. "Lunch".Now.. is there any way I can select an item from my database records (right box) and add them to an empty listbox that I'll save to a txt file. The database box is called "FoodItemsDataGridView" but maybe I don't even refer to that, I have no idea..

I have a listbox with all items related to a person written in one line, e.g. Name, Gender, Phone #, Address, Email (all separated by a ControlChars.Tab).. How do I choose each individual item alone, e.g. Name, from a line to put it in a separate line in a file.This isn't working.. Can you tell me what code to use?
Dim outputFile As New System.IO.StreamWriter("Info.txt")For i = 0 To lstAllInfo.Items.Count - 1outputFile. WriteLine(lstAllInfo.Text.Substring(0, lstAllInfo.Text.Substring (" ")))Next outputFile. Close()

I am not sure how I could achieve this: allow the user to select a value (string) from the dropdown list of a ComboBox and display another value in the editable text. The user can modify this displayed value as well. In VB6 I had a combobox where the list property contained a two dimensional array. When the user selected a value from the dropdown list, the displayed value was set using the second dimension of the array. Something like this:

I'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."

We have an application with an mdicontainer form which has a menustrip with many toolstripmenuitems. Each of these toolstripmenuitems has dropdown items. We want to be able to set the Visible properties of these dropdown items to true and false in various situations. We are able to do this e.g, mnuFileOpen.visible = True and it does make the menu item visible.

net/watin application and I am trying to select and item from a combobox on a client's website. I can use watin to drop the list down and select (highlite) an item from the list but the selected item will not populate the textbox above. It seems like watin's .select() is not triggering an event to fire.I can work around this by writing in the first letter of the item in the combobox and use the hypertext feature to select the item but this is not ideal.
