don't know if anyone can help me out here. I have a combo box and basically when the user selects an option from that combo box, I would like it to produce text and an image in a group box to the right of the screen.
I have my layout set up but am unsure how to code the combo box to produce my output.
I'm using Vb .net 2008
I could use some advice/examples to acheive the following:
I have 1 form, 4 text boxes, (textbox1 ,2, 3, 4)
Textbox1 and Text box 3 and single line text boxes.. Textbox2 is multiline.. (a description field which can be as long or short as the user desires..)
Textbox 4 is a large multi-line textbox that will contain the output of Textbox1,2,3.
I need to find out how to output the contents typed into Textbox1,2 and 3 into Textbox4 while maintaining formatting..
For example, contents of Textbox1 should always be the first text displayed in textbox4, immediately under that should be the contents of Textbox2, and under that, Textbox3
I want to ensure that the text is displayed in that order even if the user enters information into Textbox3 first.. and still displayed in the proper order if Textbox2 has 1 line of text or 20 lines of text.
How could I do this? How can I make the text from one box always be inserted before or After text from another specific textbox when its displayed in the destination Textbox.. (think of Textbox4 like a "preview window" of sorts.. which will later be outputted to an actual txt file.
What I am trying to do: There are three powershell scripts with different time delays as shown below.I am trying to run them asynchronously in .NET and I followed this article to implement Asyncrhonous programming. Where I am stuck:The I am not able to retrieve output after the events are invoked.The scripts are being called but then the program ends and it shows "Press any key to continue" in console windows.I don't what I am missing here.

i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.

How to use a databound combo box to display one field in the drop down, and another as the combo box text on roll up? Using VS 2005... For example, I have a datatable that has 2 fields. One called "ShortDesc" and one called "LongDesc". I want to be able to see the "LongDesc" column values in the drop down on the combo box. When I make a selection, I want the text in the combo box to read the corresponding "ShortDesc" value.

I am getting an error when i try to populate some combo boxes with a value, the combo box has values in and the right amount the code is getting the right number.
the error msg is "Object reference not set to an instance of an object."
Combo box 2 is filled based on a selection made in combo box 1 and a listview is populated based on the selection made in combo box 2.When the LostFocus event completes in combo box 1, it hits the LostFocus event in Combo Box 2 but it shouldn't. How do I prevent this from happening or if I can't prevent it, how do I work around it? The following is the code used.

Dim myProcess As New Process()
Try
Dim s As String
myProcess.StartInfo.UseShellExecute = False
myProcess.StartInfo.FileName = "flac.exe"
[Code] .....
The AppendText runs and works on an initial run of the exe, but the problem is that not all output is redirected. when using parameters I get no output from the stream, but running flac.exe at the command prompt reveals output of course. Does anyone know anything about redirects and how to make the above code redirect ALL output from the exe?
flac.exe is a lossless audio codec utility. I am making a frontend for it.
In my programming class, we have been set a task in which a user inputs 8 numbers, and those 8 numbers will be split into groups of 4 (therefore having 4 lots of two digit numbers). These 2 digit numbers will then translate to a specific time, day, place and city.
For example, this table below is what we have been given for city. (there are separate tables for time, day, place with different 2 digit numbers)
(Excuse the formatting)
City Code
London 11
Paris 37

For example, if a use inputs 11995467 I would want that to output London (being the number 11), [a PLACE = 99], [a DAY = 54], [a TIME= 67]
Bearing in mind I am a newbie, and my knowledge of VB is minimal. How would I go about doing this. It's suggested we use MOD and integer division, but I don't see how it can work.

I am running a stored procedure and presenting the data back to users in a simple datagridview. I'm unable to figure out a way to filter my data through the SQL side, so I wanted to see if I could filter data through the datagridview. Basically my sql query returns back values of "activity" that are either added or deleted, and I only want to present data back to users that are "added.' Is there a way to do this by filtering the contents of the datagridview?This is what I have in my codebehind for the page for both the SQL connection string, and the stored procedure. I'm assuming that this would be where I would filter the information.

I am pulling different information from the same file at two different times: 1) The first time, I pull information that is inserted into a combobox. I need to use the combobox as a filter for when I pull the information a second time. 2) I pull different information from the same file, and it is outputted into a datagridview table. I already have a filter in place when the information is pulled the second time, and I was wondering if I could add to that filter or if I have to make another filter? The filter (or filters) will be used to filter the information in the datagridview before it is outputted in a chart.
This is the code for binding the combobox to the information
Dim cnRange As String = "provider=Microsoft.Jet.OLEDB.4.0; " & _
"data source='" & strFileName & "';" & _
"Extended Properties=""Excel 8.0; IMEX=1; HDR=No;"""

I know it is possible to have more than one audio output device attached to a computer. For example, my home machine has a soundblaster card as well as stereo speakers attached via a USB M-Audio controller. I know that windows and other applications can select which output device to use... I use the sound card for normal Windows sound, but I use my M-Audio output when mixing music in Cubase.The question is, from inside my own program, I need to be able to detect what audio devices are available, show the user the list and let him choose one, and then use that output device for all audio output generated by the program.
It would also help if I could determine which audio output device is being used by Windows.
Oh, almost forgot, I am using Microsoft.DirectX.AudioVideoPlayback.Audio to play mp3 files.

How do you make the autocomplete feature on combo box in VB behave in the same way as one in VBA?
the VBA properties are as follows:
MatchStyle = fmMatchEntryComplete
MatchRequired = True
The VB properties are quite different and i havent got a satisfactory combination. I need it to suggest items from the list as i type but insist on a match with the list. However on VB forms, unlike VBA forms it doesnt show the suggestion in the combo box itself, but in a box beneath.

View 3 RepliesI would like to have my output in columns, and the numbers in two digit after the decimal.
I am writing a data validation app where the app asks the user for input like give me a number of double type: and hopefully the user will comply.
But the app will test some validation rules and then:
1) if the user simply pressed enter the app will tell the user all sorts of reasons why the input was rejected. And that part should look like a table with columns for the entry, if it passed true, otherwise false and then the reason line empty input. Or this number is a string.
