How To Manage ComboBox And ListBox
Feb 27, 2009
What I want my program to do is to make a selection from the ComboBox and it will be added to the ListBox. If the selection is already in the ListBox, a message will appear.
Note: Project / Properties / Option strict is On
This is my codes, but the If-Else doesn't seems to work.

I'm sure there is probably a better way and certainly a more correct way to do with. But, right now when I output to the listbox, I'm only getting the information from the last item in the array.
Public Class frmInvoice
Structure Invoice
Dim intNumber As Integer
Dim strTitle As String
Dim strDescription As String

Trying to learn VB 2005. So my questions might tend to use the logic from VBA/VB6.
So, my question is, is it possible to assign indexes on the listbox/combobox? What I have is an ID and a Description from a table and would like to display it on listbox/combobox to allow user to choose from by looking for required description. When selected the ID will be used to search for other information related to this ID.
I manage to display the description but how to assign the IDs?

I need to extend a combobox to disable some listitems (i.e splits - "----------"). I reckon some APIs will be involved, and it could get complicated. That'll not put me off though. If anyone with usefull info on the subject could post it,

(All of the names on the ListBox are actually .txt files, which contain different values that can be put into the program by a certain window.)
I'm trying to use a ComboBox to order items in a list by a certain value. So say I select "Sort by Alphabetical" in the ComboBox, I'd want it to sort the items in the ListBox in alphabetical order.
Also, if I were to have a certain value in the .txt files that I would like to sort by, is there a way I could order by that?

On the form, I have combobox1, combobox2, datagridview, and a listbox. Basically, combobox2 displays a list of street names. My problem is that once the user selects a street name from combobox2, the listbox should be populated with only the customers' names who lives on that street. How can I go about populating a listbox with just the customer names? Originally, the street names include the house numbers as well. For example, "5100 E Dublin Granville Rd". Fortunately, I figured out how to display ONLY the street names ('E Dublin Granville Rd') and not the full street address to the combobox by adding the following public property below. However, I am still encountering a problem because now the combobox has duplicates of the same street name![code]

It works just fine if I use pctrlListBox As ListBox or if I use pctrlCombo As ComboBox, but I need to be able to use both with the same routine.
(PS: Yes, I do have a leap year check in here which I took out as it is not germine to my translation problem.)
(PPS: Using a control such as the monthview or datepicker is not an option.)

I have a combo box with a list of Coordinator IDs, one Coordinator can run many subjects. On another form I have a list box that contains a list of the subjects, and another list box that has the coordinator that teaches the subject. The positions match up, i.e if there is a match for the co-ordinator ID in the list box at position 3, I want to extract the subject list box at position 3 also. The problem is 1 coordinator can teach more than 1 subject. Basically I want to show the subjects taught by the Coordinator the user selects in the combo box. I have tried the following but have had no luck:

I have a total of 102 values associated with a fieldname called ArrivedFlag.Then I have a TextBox control with an id of txtFlag on the markup page.In my codebehind, I have an if statement that says:
If txtFlag <> "value1" and txtFlag <> "another value" Then
lblMessage.Text ="You don't have the ability to view details"
end if
This works fine.However, given that there are 102 values, I feel that doing an IF statement 102 times is a bit inefficient.
Dim allowedFlags = New List(Of String)()
With { _
"value1", _
"another value"

I was asked by a client to create a tool that would let a user add/modify/delete/read content from a database. The content can be read from TextBoxes.
My question is, what is the best way to manage GUI locks/unlocks for the different states of the program. IE: If I'm in a "insert" mode, some GUI elements should be enabled, and some not. If I'm in the "read-only" mode, a bunch of them should be disabled... etc.

I am writing a program that uses an array with three columns and a varying amount of rows. I need to load info on a list of files in an archive(specifically: file name, size, path), and I am wondering what the most convenient way to store strings(to be loaded into the array) is.
For example: I tried creating a new .resx file in my project, and writing a function to be executed on form1_load that reads the strings from the .resx file and places them in the array in their correct column, but unfortunately had no success.
I really have no idea how resx files work, I can put strings in them using the resource editor, but I don't know how to retrieve them using resourcemanager.
I would just put the info straight into an array, but it's much easier to update a .resx file when the archive changes than it is to update the code.
Could someone please tell me how to use .resx files in vb.net? Or an easier way of accomplishing my goal?

I can't manage to add different values together...
TextBoxAnswer.Text = TextBox1.Text + TextBox2.Text + TextBox3.Text + TextBox4.Text
I import decimal values from my SQL Server into the TextBoxes 1-4, which works fine. But when I try to add the values together into another textbox the answer is just the values combined like a string...?The column of the table in the SQL server has a datatype decimal(18, 2)I have also tried to convert the values in the textboxes into int, str, double... Nothing seems to work...
Example:
Answer = 2,50 + 2,50 + 5,50 + 4,50
So,
TextBoxAnswer.Text = 10,00
but, all I get is:
2,502,505,504,50

I am now convinced there is no such thing using VB 2010 Express. I have read, re-read, studied, copied and pasted code to no end and all I get are error messages galore. It appears there is a big gap between what's on line as far as tutorials and the code that VB 2010 Express will accept. I hate to sound so lost but at the moment I am. I used to program in BASIC and QBASIC. I was a master at opening up ascii text files, reading them in sequential order, sorting, manipulating, then re-writing them. It was all so easy, like this: [code] That's all I want to learn how to do for the moment. But every tutorial or article I find goes off in to wild tangents about How to Manage Directories or it reads the entire text file into one giant object. Or worse, there's some code which looks promising but it won't run under VB 2010 Express or it might run but the author leaves out important parts of the code that have to be declared ahead of the subroutine....you all know what I mean. It can't be this difficult to just read a text file one line at a time, therefore it shouldn't be so difficult to find an accurate and up to date article on this.This is for really rough programming. I don't need an interface of any kind. The user, will not even need to know that anything is happening. I simply want to read text files, manipulate what's in them and then re-write the edited text.

How can I make that kind of change?
An example:
Sub ChangeValues()
Dim A As Integer = 1, Str As String = "Start String"
Dim X As MyClass(A, Str)
X.ChangeInt(2)
