I'm currently trying to add all the sections of a specified .ini into a combobox.[code]Now that's my section in the .ini, but it's scrambled and placed into multiple lines. I just want it on a single line as said in the .ini.Does anyone have any idea how to get values between brackets "[hi]" and place the value between the brackets into the combobox items?

I have an Access database with a Parts table. I'm using tableadapters in my project. A datagridview on my form is filled manually in code. One column of the DGV contains a columntype of combobox. I've got a bindingsource on my form whose source is the Parts tableadapter. The combobox column is tied to the bindingsource and is displaying fldDescription.
The part descriptions can be changed by the users, but the original part description is saved in another table that is used to fill the grid. If part "widget" gets changed to "widget, large" I can no longer display "widget" in the combobox of the grid. I need to know how to be able to add it to the bindingsource so I can display it in the combobox. I don't want it saved to the Parts table though.
I'm new to vb.net and I have what probably is a simple question, but one that I am stuck on. I'm trying to add a single item to a ca combo box at run time. For example, a user selects a category from the first drop down box at run time, say "Admin", I want to add a single item to the combo box below it: Not applicable.
cboTest.Items.Clear()
cboTest.Items.Add("Not Applicable")
I want to adding checked item from checkedlistbox to my combobox, but i have a little problem here.Combobox only show 1 item last checked.This is my sample code.
If CheckedListBox1.CheckedItems.Count <> 0 Then
For i As Integer = 0 To CheckedListBox1.CheckedItems.Count - 1
cbCheckedItem.Text = CheckedListBox1.CheckedItems(i).ToString
Next i
End If
In the form below you see how the initial selected item is the first record of the table.. these controls are bound.. I want to initially show "Select one" in the combo box or nothing at all and the other controls not to be bound until an actual item is selected in the combobox..
View 1 RepliesI have developed a drawing tool that allows the user to add graphically referenced database records to a picturbox.While for testing purposes i was simply loading any picture into the picture box what i want is on selecting a building name from a combobox that it automatically populates the related floor levels (that apply to that building)to appear as a selection in a 2nd combobox. On selection of say 1st floor i want to load the relevant floor plan (JPEG)image into the picturebox.The tool i have developed has an estate builder function where you ccan build your estate profile i.e specify the buildings and floors etc and these are added to a database file. What i would like to do is at the same time specify the floor plan JPEG file location and for this to be stored in the database in a way which would enable me to load the image automaticaly when i select the floor level

What am I doing wrong it should just read
Ok, I'm trying to set a value to each item in my combobox, but I don't know how. Lets say I have ComboBox1 that contains the letter A-Z, 26 items, I would want to set each letter a specific number, then use that number for something else. Like, if I set the letter A to equal the number 4, and the user has chosen A in the combo, I could do something like make a Msgbox say that value(4). Does that make sense?

View 5 RepliesI am dynamically creating and adding a ComboBox to a specified column in DGV. I also set a DataSource, DisplayMember and ValueMember for the created ComboBox. Somewhere else in my program, I select a number ( let's say 5 ) and based on that number I want to change the SelectedIndex of the current ComboBoxColumn ( I actually loop through the Columns collection ).I tried something like this in a event handler I created:
vb.net
Private Sub combobox_validated(ByVal sender As Object, ByVal e As System.EventArgs)
Dim combobox As System.Windows.Forms.ComboBox = sender
Dim colIndex As Integer = combobox.Tag
[code]....
You will notice here, that I'm not actually trying to change the .SelectedIndex property, but the Value of the current cell.How do I reference the actual ComboBox?
I have a combobox called cbMaterialType on a windows form that's bound to a table in SQL - everything loads great and the combobox displays 'Material' items as it should, in that table I have two fields - Material (as mentioned above) which is a char(25) and InStock which is an nchar(1). If the InStock field contains a '1', I'd like the individual material to be green in the combobox, if '0', then red. I have the simple code in the drawitem event of the combobox as follows, but can't seem to get any results at all:
Private Sub cbMaterialType_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles cbMaterialType.DrawItem
If MaterialTableAdapter1.GetData.Item(cbMaterialType.SelectedIndex).InStock = 1 Then
cbMaterialType.ForeColor = System.Drawing.Color.Green
Else
cbMaterialType.ForeColor = System.Drawing.Color.Red
End If
End Sub
I've never worked with any form of color in comboboxes before and this is my first attempt at the drawitem event.

I have a function that is suppost to take a list of strings then split up each part. This is my code
For i As Integer = 1 To UPdata.Count
If InStr(UPdata(i), "!!") Then
Dim DataTBP() As String
Do
DataTBP = UPdata(i).Split("!!")
[Code] .....
One section of UPdata would look something like
ABC#DEF@GHIHSJD!!143#ISJ@PSIODH!!
What I want it to do is firstly separate the lines using !! so i would be left with
ABC#DEF@GHIHSJD
143#ISJ@PSIODH
That part works fine and I am left with an array DataTBP() with 2 values. The strings found above. Its then suppose to extract the part before # for every string left in DataTBP (In my example two) but the function that's meant to do this:
For j As Integer = 0 To UBound(DataTBP)
Dim DataType As String = DataTBP(j)
DataType = DataType.Split("#")
Select Case DataTBP(j)
[Code] .....
Throws me the error
Value of type '1-dimensional array of String' cannot be converted to 'String'.
But I don't know why as DataTBP(j) is a string not an array but a string. I've also tried
For Each a As String In DataTBP
Dim DataType As String = a.Split("#")
Next
It throws the same error

View 1 RepliesI have 13 variables, all called Items1, Items2, Items3 and so on. I have a combo box with items in, each time I click a button I want it so whatever is selected is stored in a variable and if the button is selected again then it stores whatever is selected in the next variable. I know all the code for selecting items in a combo box and transferring it to a variable but the problem I cannot do is the part where each time a button is clicked it stores whatever is selected in the combo box to the next variable.
View 9 RepliesI have a problem in my code I can't seem to find a solution for.. One combobox is being filled up with a datatable like this:
CbUsers.Datasource = usersDAO.getUsers()
The getUsers() returns a datatable from my acces database. Users have a name and id, I want to use both of them but it should be something like this:
CbUsers.DisplayMember = "username"
CbUsers.valueMember = "userid"
In other words, I want to see the user name, but work with the user ID. So far the code worked, but it only displays stuff.
Now, in a method I want to use the id of the selected user in the combobox but that has been given me some trouble.
If I use this line I get a DataRowView: CbUsers.selectedValue
When I try to retrieve information from it, it throws an exception. I've tried lots of different code and it never worked..
If I put the DataRowView in a local variable and do this:
id = drv.items(0)
I only get exceptions..
