I have a private sub that I have to call in different times with different textboxes when I click a button. So I made something like this private sub [just some things to change D link into V link not really important]:
Private Sub DtoV(ByVal input As String)
Dim vlinks As String
If input <> "" Then
[code]......

View 1 RepliesI'm trying to get a handle on creating my own Interfaces for a project I'm working on. I know the MSDN help shows that all member signatures will become Public when implmented, etc, etc. However, if I implement the IDisposable interface provided by the framework, comments and private members and fields show up! Not only that, but some of the methods have comments and code within!
How did they do that? And can comments, private fields and members, and predetermined code be declared as part of an interface by the average developer?
I am trying to call this private function, but am missing somthing, anybody point me in the right direction Private Function DL_WebPage(ByVal _URL As String) As String This is what I have tried, but with no success: call DL_webpage But this comes up with an error
View 3 RepliesProbably an easy question to answer...I have 9 buttons on my form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
etc. and all do the same thing so how can I merge them into the same sub so i don't have to copy and paste a bunch?
i made this code
VB.NET
Dim iString As String
If My.Settings.IPBank.Count = 30 Then
MsgBox("You alredy have the maximum amount of IP Addresses stored, delete one to add another.", MsgBoxStyle.Information, "Program Error")
[Code]...
I want it to check all of the items in the my.settings.ipbank which is a stringcollection. Before it adds and if it already exists in my.settings.ipbank then i want it not to add it. But it just adds when i run it. And then once its added it says: "Collection was modified; enumeration operation may not execute." But also before i run it. There is a warning saying: Function 'AddTo_IPBank' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used. Is this something to do with it? I think i have the Next in the wrong place .

View 2 RepliesI have these list of RS-232 strings declared in my public class
Public Class TouchInterface
Dim WatchTVbtnCmd As String = "rs232command1"
Dim VolUpbtnCmd As String = "rs232command2"
Dim VolDownbtnCmd As String = "rs232command3"
Dim SystemOffbtnCmd As String = "rs232command4"
Dim RadiobtnCmd As String = "rs232command5"
Dim MusicbtnCmd As String = "rs232command6"
I then have this private sub. For the sake of this thread, what I would like to do is get the name of the label that was clicked which in the code below is already done, convert it to string (not sure if this needs to be done), this is also done in the code below. Next I want to compare the labelnamestring to all the variables in the public class to find out which one it is equal to and then disply that variable which should be my rs232 string in the message box. I have also added "Cmd" to the variable names above so I also need to work out how to add the text "Cmd" to the string to properly compare.
Private Sub Musicbtn_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles WatchTvbtn.Click, VolUpbtn.Click, VolDownbtn.Click, SystemOffbtn.Click, Radiobtn.Click, Musicbtn.Click, GardenVolUpbtn.Click, GardenVolDownbtn.Click, GardenRadiobtn.Click, GardenOffbtn.Click, GardenMusicbtn.Click, GardenMediaCenterbtn.Click

i have have a few questions about the syntax of the lan.:
1) What is the 'Get' statement and when do you use it?
2) Whats the difference between public, private, protected etc... when declaring functions and subs.
3) When would you use the overrides property?
When I develop a Windows Forms app in Visual Studio using C#, every control that I add to my form is by default marked as private, which is what I want.
When using VB.NET, every control is by default marked as Friend (the equivalent of internal in C#), which is not what I want.
Can I just change this default? It seems like surely it's a setting somewhere.
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.

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.
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.
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
[Code]...
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.
