I was hoping someone could help me please, how do you list all files in a directory in a combobox?
The following works to display all folders.
cbolist.Items.AddRange((From folder In New IO.DirectoryInfo("Path").GetDirectories Select (folder.Name)).ToArray)I have tried the following but it fails
cbolist.Items.AddRange((From folder In New IO.DirectoryInfo("Path").GetDirectories Select (file.Name)).ToArray)
I need to display column from

table : some
columns:

I have a two ComboBoxes. ComboBox #1 displays...
Directory 1
Directory 2
Directory 3
Whenever I pick any from Directory 1, Directory 2, or Directory 3, I will display all sub-directories of that chosen Directory onto ComboBox #2. If I choose Directory 1, I will populate ComboBox #2 with all the subdirectories of Directory 1, and so on.
[Code]...
I hoped that I did explain that properly. Let me know if I need to clarify something up. Oh and let me stress it again, I'm trying to get the directory structure from a UNIX-based system and I'm trying to display it in VB (windows-based).
Web browser question from stupid newb: How do you make the url of your current web page show up in the navigation combobox or textbox?The actual problem is when I go to a web page and click an internal link or use the back or forward button it only shows whatever the last webpage I keyed in and not the actual page I'm on.

What I am attempting to do is make a form for a tire shop. I want to put comboboxes on the left side of the form that the employees make choices from. I then want to put some kind of a table or grid looking thing on the right side of the form that will display their choices so that everyone in the shop can look at it see that "John is on bay 5 until 3:00pm". At the end of the day I want all of the combobox choices to save to a file..I dont really need the table or the grid thing to save..just the choices. If I want to do this, do I need to use that gridview tool? or can I make my own table thing to display the choices in.
View 9 RepliesI 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 combobox which contains a sample of names selected from a table.Currently the default name displayed in the box is the 1st name found in the table.

View 7 RepliesI'm working on a new version of something I had created years ago in VB6. What I was doing then is populating a combobox with lines from a sequential file ("title","URL") like this:
Open "data.dat" For Input As #1
Do While Not (EOF(1))
Input #1, NameInput, URLInput
cmbEntry.AddItem NameInput
Loop
And then checking against it on a button click to load the URL associated with the selected name:
Open "data.dat" For Input As #2
Do While (cmbEntry.Text <> NameInput) And (Not (EOF(2)))
Input #2, NameInput, URLInput
Loop
[Code] .....
What I'm trying to do in Visual Basic 2010 is the same process, though I'll be including a third field ("category","title","URL") to determine which one of four different comboboxes I add the entry to. I know I need to use streamreader, but I'm not finding much in the way of documentation or examples on how to do what I'm trying to do, which is:
- Populate one of four comboboxes with the second value in each line of an external text file, based on the first value in that line
- Set a string to the third value in a line of an external text file, based on the second value of that line
How to read these values from the file.

View 5 RepliesI'm new to Visual Basic.net, I've had some experience with ye old visual basic however.

It is in the following format QUESTION NO: 1 This is the question, what is the answer?

D. Or this Answer
Answer: D
QUESTION NO: 2 and so on. I would like it to display the question number in say...a textbox, along with the question and the multi-choice. And then depending on user input, says correct or incorrect.
I need to have two pieces of software, made in vb where one encrypts the contents of a .txt file, and the other decrypts it, and then picks one word at random and displays it each time a button is pressed, but never displays the same word. Or, if there was a way to hard code it into the program as there is only 5 words that would be better.

View 5 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?
