VS 2008 - How To Load Text In ComboBox
Oct 5, 2009
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 would like to load a combobox with some values from an access database. On form load I load my information into a data grid view but if the user wants to add more information or edit what is selected in the DGV I will enable some text boxes and a combobox to show the selected data. I have not issue loading from the DB into the text boxes but the combo box has me a bit stumped. I have 3 columns in the database, periodno, start date and end date. I want to display the start and end date concatenated together. When the user selects a period and hits the button I want the dates to set a variable with the periodno that matches those dates.

i had this working and i foudn the info on this forum, but i cant for the life of me renemebr how to do it, and searching for the thread all i can find is this:

Which is not it, the method i used only involved a few clicks per item to set up and it made it so what ever selection was chosen in a combobox for example was saved, and then that selection was loaded on the apps next run, i know i had to do something in the application setting/databinding area of the properties.

I have a rich text box which I use in order the user is able to add pictures, coloured writing, different font etc... however I need to load specific text in the rich text box when the user load the Form.how I can add (I guess) the HTML to load this every time the user load the form.
P.S the text will change depending on who loads the form so I can not do a simple

Right now I am trying to make a combobox from a SQL table, it looks something like the following:
id|name|
---------
1|square
2|round
3|triangle
The combobox that I want should display the "name" parts, and I have made the code to display it correctly:

Basically the application I'm creating has a login screen with two textboxes and one ComboBox... Once the user enters their first and last time for the first time it'll be stored in the combobox's index..Now my issue is this... Originally before I implemented the combobox the related user file name would be:"C:FicheStatsJohn SmithJanuary" + Ttbox1.text + Textbox2.text + ".txt"So basically the user filename would be JohnSmith.textBut now I want the user to directly select from the combobox and that the file name remains the same without space.... but in the combobox the name appears as John Smith.>

I've got a combobox - style DropDownList.
Three options - blank, EMAIL or PHONE - these three are set at design time.
Do I just bind the TEXT property of the COMBOBOX to the field in the DATATABLE?
This appears to be working fine - but I'm a bit confused about the purpose of SELECTEDVALUE in all this. I'm not binding to that.

I have a text file, with several lines of comma delimited data. The easy part is that each item fits into the same field, so I can use a 2 dimensional array. I would like to use .net classes to do this, not the old file handling functions I was used to.How can I take the text file and load the data in the text file into a 2 dimensional array.Here is example data in test.txt
1,1,1,2,2,2,1,1,1,3,3,3,4,4
2,3,4,5,1,1,1,2,3,4,5,1,1,1
2,3,4,5,6,1,1,1,1,2,2,3,3,4
So this would go into a (14,3) array.I would like to make sure, that the array is automatically sized to the size of the data also.

I'm trying to read and load the content from the attached text file to a arraylist with the code bellow.
but what is happening is that not all the lines from the text file are loaded in to the arraylist, the reading jumps from one line to other in the text file.
Dim FILE_NAME As String = ((My.Application.Info.DirectoryPath).Substring(0, (My.Application.Info.DirectoryPath).LastIndexOf(""))) & " est.txt"
Dim lista_barras As New ArrayList

I need to load a large txt file that is in a fixed width format. There are over 45K lines, so speed is important.I need to load one of the fields into a dropdown box and have another field (label) display the text of another field in the related line.I could import the file to an access db if needed, but would rather not as i also want the txt file to update from a link on a regular bases. So having it in a DB would be more work to process that part.[code]

I have a data-bound combobox that pulls values from a BindingList(of T). Combobox loads fine, correct values are displayed (I'm not using SelectedItem or SelectedValue). I'm using properties and connecting the data to the control via a bindingsource.
What I want is if the user types text into the combobox, I want the data from the bound table to change to that new text, i.e. edit the bound data directly.
Easy as pie to do with a textbox, but can't seem to get a combobox to work this way.
I was trying to use the validated event of the combobox to write the data to the datasource, but it doesn't fire when I press enter. Is that the way to do it? Can I not link the data to the combobox directly?

I have a program that needs to display a playlist of songs, for a band performing someplace, from a .txt file. The songs in the file are listed as follows:
All You Need is Love-Beatles
Rock
4.25
[code]....
The first line is the song's title and group name. The second is the songs genre. The third line is the songs length, 4.25 is 4 minutes and 25 seconds.upon clicking a button, I need to display a playlist from this .txt file based on the number of minutes the band has to play, minutes entered into a TextBox, and the songs genre, selected from a ComboBox. The songs cannot repeat and must be random.I have already coded the program to read the .txt file but have not clue where to start with the rest.

I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.

I had added the items
1
2
3 to the combobox.
Then I gave the "Select" to the text of the combobox.
How can I able to reset combobox to select the text("Select").
I had tried by giving -1 to the SelectedIndex. But it gives only Empty.
This is for VB.NET Windows Application
