View 3 RepliesI have a drop-down ComboBox, where the values are a range of indexes, followed by a key value. So one line looks like:01 : 01010101010101010202020202020202
I have set the ComboBox up so that on the form, only "01 :" is displayed, but the DropDownWidth allows the entire string to be seen when the dropdown arrow is clicked.However, once that is done, I am left with "0202" (the last four characters) showing in the ComboBox, rather than "01 :" until the control loses focus. How can I force "01 :" to display?
I'm new to VB and as every beginner i've begun with a browser, i've added a combobox that records the current url of the website and adds it to a "history" combo box, the problem is that when i go on a site once, the site name shows up multiple times in the combobox. I was wondering if there is a code to only add a certain value only once,

I am not sure if this is the right area but I am new to Visual Basic and what I am trying to accomplish is creating a combobox in visual basic 2008. I have made the box and put in the list i needed but programming it to what I am needing is not working right. What I am looking for is the proper code when selecting an item in the dropdown and clicking next it will run an application (most are going to be .bat files). Like if I select Admin Batch in the list and hit next it will run admin.bat or if I select Printer Install then click next it will run printerinstall.bat.

What ever happened to the readonly method in the ComboBox? So i thought if MS did not have that option let me code around it. So i made a code herethat checks if the user inputs something else then what i want him to input.If it something else is found it returns the text back to "Hours(s)"But why do i get this error?

how to create a datagridview with the "main" datasource one table, and one column of this table it's a column (combobox) related with another table.I'm doing this all by code, but i have several doubts how to achieve this.First i had allready created the datatables in memory, the first one have only 3 fields (pk,info,size) the size field it's the field that's related to the the other table (id_size,size_text). Then i inserted the only roms that i need in the second table (dtUni)...In the previous steps i don't have any problem, but now if i try to add a constraint to relate the columns, something like this:VBdsTemp.Relations.Add("fkRel", dtAcess.Columns("id_size"),dtUni.Columns("size")) I get an error saying that the column doesn't exists in dtAcess.
View 1 RepliesI am running VS2008 and developing a Windows Form App in VB.Net. Is there not a bound multicolumn combobox like Access has had forever? If there is one buried in VS2008, the Windows OS or MPF 2010 or somewhere else would you mind sharing? I could hardly believe my eyes when I did not see one in the common controls list.
Not knowing the correct terminology, I would like this control to be a tool component that I can drag onto my form and set the binding and column properties and be done with it.Come on Microsoft VB.Net Dev Team... where have you been on this? This type of control has been out for umpteen years in Access and 3rd party took kits. There is nothing that says Rapid development like roll your own code! I have seen serveral articles on how it can coded;?

View 14 RepliesI am trying to populate a combobox using the following code.
CODE:
I have a datagridview for the transactions table. On the datagridview there is a combobox column for the type id field in the transactions table. This combobox displays the transaction type name from the transaction types table and puts the transaction type id into the transactions table. That much is okay. But each transaction type belongs to one of several categories. I have a categories table. The category id field in the transaction type record points to the id of the categories table. The category id is not in the transactions table, it is in the transactions types table. I need to know how to link the categories combo box on the datagridview to the category id in the transactions types combobox, which isn't even there right now. At present the transaction types combobox does not display the category id. It displays the transactions type name. Do I need to add another combobox to link the categories combo to the types combo?
I need to have it first and foremost so it will display the correct category when existing records are pulled up. I think I could do this with a join to the transactions type table in the categories combobox. But that wouldn't cause the transaction type combo to filter by category when a new entry is made.
Can someone advise as to the correct way to link comboboxes in this type of heirarchy?
I am using VB.NET 2008 and an Access database.

I have some subs that I use that I could make more universal if I could have a ComboBox variable so to speak.
Me.ComboBoxCMFrac.SelectionStart = Me.ComboBoxCMFrac.Text.Length
For the above code is there a way to enter a variable that could be set to whatever ComboBox you wanted. I tried
Dim ObjectComboBox As Object
ObjectComboBox = ComboBoxCMFrac
ObjectComboBox.SelectionStart = ObjectComboBox.text.length
It doesn't accept that in the editor but I'm showing you what I would like to do. If there's no way to do it fine but if there is a way I'd like to know how.
I have tried searching on if it is capable to do autocomplete in a combobox in the datagridview control. I was planning to use the combobox in the grid itself. There is a property to set autocomplete true/false but I cannot get the cb to let me enter text to find. It only selects on the first character of items in the list.

I have a combobox (cbKeyWords). I want to make sure tbAddEdit.Text does not already exist before I save. To me I should be testing for a False result not True. But the above code, goes to the msgbox if findstringexact=false and saves the data if it's true.
Controls: textbox, combobox and button
I want to have a condition to find out if the value I enter in the textbox exists in the combobox. The combobox reads a text file.
I want to make it so you can type a name into an input box and have it go into your combobox1. Then also have it to where you can load a list of names into your combobox from a text file where the text in the text file would be like this
NAME 1
NAME 2
NAME 3
NAME 4
So it will enter in the combobox1 like that. Also, This is an account maker, So I was wondering how I would make it so after it creates the account it will use the next text, can I just use the "Next" method?
I am trying to populate my combobox from Access, I decided to use a function in a separate module to connect, querry and return the result to my combobox for the sake of diminishing the number of lines, but I can't get it to work in .net.
Here is the module I modified from what I found on the net:
Module DataModule
Dim cnn As Data.OleDb.OleDbConnection = Nothing
Dim DBpath As String = My.Settings.SDBPATH
Dim SQLString As String
Private cnnOpen As Boolean = False

I remember .eof method for my "While Not" loop but I can't seem to make it work. Basically the table in my DB consist of 2 columns, the first being ID (autonumbers) and the second are the records I want to access via my combobox, there is about 10 rows for now but it is subject to change.
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?
