VS 2008 - Combobox And Comma Separated Textfile Value Loading In To A Textbox
Jun 11, 2010I am trying to write a vb2008 program that allows a user to select an airport from a combobox and then once the value has been selected it searches a comma separated text file once it has found the airport selected ( always the first column in the file) in the file it populates 8 other textboxes with the row data from the file. The idea is to select the airport and then it calls up the radio frequencies associated with the airport.I assume you have to call the data into an array and the search thorough the array until the combobox.selectedvalue = the value in the array, but i am unsure how to do this Ideally I would like to be able to the user to add data to the file thats why I used a combox, but I am having trouble trying to get the boxes to populate so first things first.

Loading A Textfile With A Number Greater Than 999?
May 27, 2012I have data which can be put inside listboxes, I then proceed to save the data into a textfile then attempt to load it. This all works great until a number of over 1000 appears because it's read as 1,000 and VB thinks the Comma means to go onto the next field.
'put record into the line in correct format
sLine = sCallCentreOperatorID & "," & sCallCentreName & "," & sQuoteNumber
sRecord = reader.ReadLine

I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.
Select A Particular Value On A Combobox By Looping Through Combobox Items?
Jan 5, 2012I have a form in my vb.net application used to take the data about the returned stock. The form contains two comboboxes. One, named combobox5, contains invoice numbers and the other, named combobox3, contains party codes. Both the comboboxes are pre_loaded using sqldataadapter.
Now what i want is to change the party code in combobox3 when the invoice number is changed in combobox5. Elaborating it further, When Stock is issued the party code is stored along with the invoice number to keep track of to which party was the stock issued. Now when stock is returned i want to keep track that which party has returned the stock and i want that the party code should be automatically selected when the invoice number is changed and it should be what is stored in the database against that particular invoice number....
I'm using the following code for doing so:
Private Sub ComboBox5_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox5.SelectedIndexChanged
' defines a new connection to the database
Dim con As New SqlConnection("Data Source=TAHA;Initial Catalog=ADT;Integrated Security=True")

Loading Combobox Into DGV?
Apr 22, 2012I have been working on a solution that uses Combo Boxes to fill DGV I have 3 RDM tables, 3 Combo boxes and 1 DGV Probably best way to explain tables is this way
Table 1 OwnerID 1, 2, 3, 4, 5 ( There are 5 owners)
Table 2 CDID 1=(1,2) 2=(3,4) 3=(5,6) 4=(7,8) 5=(9,10) (each Owner has 2 records)
Table 3 CDTrackID 1,1=(1-10) 1,2=(11-14) 2,3=(15-20) 2,4=(21-27) 3,5=(28-36) 3,6=(37-40) 4,7=(41-44) 4,8=(45-47) 5,9=(48-55) 5,10=(56-60)
where 1,1=(1-10) means
Owner 1 record 1 has 10 records and
Where 1,2=(11-14) means
Owner 1 record 2 has 4 records
etc etc
On Form Load Combobox 1 loads all the data from table 1 with no output in DGV (Works well) (5 records Perfect)
When I select a record from Combobox 1 it loads relation data from table 2 into Combobox 2 and also displays same in DGV (Works well) eg if I select record 3 in combobox 1 it loads records 5 and 6 into combobox 2 and DGV (2 Records. Perfect)Now comes the Problem When I select a record from Combobox 2 it is supposed to load the relation data from table 3 into ComboBox 3 and display same in DGV eg Combobox 2 has records 5 and 6. If I select record 5 It should load 3,5(28 - 36) OR If I select record 6 It should load 3,6(37 - 40) instead If I select Record 5 then Record 1,1(1-10) loads into combobox 3 and DGV If I select Record 6 then Record 1,2(11-14) loads into combobox 3 and DGV Regardless of which record I select from Combobox 2 (1,2); (3,4); (5,6): (7,8); (9,10) it always loads the same records into combox 3 and DGV Sample code for combobox 1
SQL = "Select * From CD Where OwnerID-1 = '" & cbxOwner.SelectedIndex & "'"
Sample Code for Combobox 2
SQL = "Select TrackName From CDTracks Where CDID-1 = '" & cbxCD.SelectedIndex & "'"
[code]....
The only thing I can think of is that my query constantly sees 2 records and numbers them as 1 and 2 thereby displaying records 1,1(1-10) OR 1,2(11-14)?

Nov 12, 2010I have a list of a few 1000 names, which I need to load in several comboboxes.

Sure I can add then in a database and load them, but that takes more time then loading a file from the hard-drive.

Loading Line Into ListBox - No Empty Items
Dec 15, 2011I've got a Program and a text file, this text file gets load into the list box but that's not the problem. The problem is that when I make the text file it makes a open line and this line gets loaded into the list box and I don't want empty items.
So here's code that I use to make text file
Public MySettingfile As String = My.Application.Info.DirectoryPath & "Process History.MemFreo" Dim myCoolWriter As New IO.StreamWriter(MySettingfile, True, System.Text.Encoding.Default)
myCoolWriter.WriteLine()

Forms :: PictureBox - Image Loading Using ComboBox
May 14, 2009I have a picture box on my form along with a combo box with a number of different options. So anyway when a combo box item is selected I want it to look in the dataset for the selected item's row and pick out the image to load and then using an IF statement it sets the image (or should).
Dim RaceImg As String = DS.Tables("tblRaces").Rows(ID).Item("RaceImg")
If RaceImg = "AusGP" Then
GP_Picture.Image = Image.FromFile("./Track Images/AusGP.png")
ElseIf RaceImg = "MalGP" Then
GP_Picture.Image = Image.FromFile("./Track Images/MalGP.png")
End If
I have tried a number of different ways to get this working, I have tried them in the resources for the program and also tried the following code
GP_Picture.Image = "./Track Images/AusGP.png"
It seems like the picture box isn't redrawing or something? Just to add it will load the first image which is the AusGP because thats the first option in the combo box, after that none of the others will load.
Loading Up ComboBox Values Once (At Login Screen)
Mar 9, 2011I have a few combo boxes that need to be loaded up once and displayed multiple times (whenever the main form is opened) The reason for this is because it's taking about 10 seconds for the form to load each time it's opened due to unnecessary re-querying. Here is an example of what I have as a combobox source and what I've done. I've put the query, connection, etc... in a module and call it on the login form - I don't get any errors but the data does not load into the combos.
'In Module
sql = "SELECT DIR_ID, DIR_NM FROM LTC_FBS_DIR ORDER BY DIR_NM ASC"

View 6 RepliesForms :: Loading Listbox Selected Items From A Database?
Sep 14, 2011I was writing a program that would save the contents of a listbox to a database and wanted to reload the users' choices when the opened up that particular row again. My first thought was to do it with two for loops, just as I used to do in VB6, but I thought there must be a better way to do it. And there was. Sort of. It basically involves using the SelectedObjectCollection class.For this demo, you'll need a listbox called Listbox1. Set selection mode to something other than "One" or else it won't work as expected

items(0) = "One"

Getting Method For Loading CheckedListBoxes And Saving Checked Items To List?
Oct 26, 2011I gather case info from a DB table into a list(of T) list and display it in a checkedlistbox. When an item in the checkedlistbox is selected (highlighted, not checked), the selectedindexchanged event then retrieves account information from the DB for that case and loads the different accounts for that case in another checkedlistbox.
My issue is figuring out the best way to save the different items that are checked in the accounts checked list box. Since the accounts are loaded dynamically given the selected item in the cases listbox, what would be the best way to save which accounts are selected for each case?Below is my current method of loading the listboxes and selectedindexchanged procedure. I'm fairly new to programing and this is how I was taught load most controls, by list after saving to the list from the DB (which gets very complicated when you have to keep relations between items in separate lists).
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
Dim CasesList As New List(Of String)
CasesList = Db.GetAccounts(CDbl(txtAccountBalance.Text))
