Thanks paul and jmcilhinney for your helpful responses. I'll have to rethink how I want to do this (as a very amateur programmer).

Thanks. Yes that works. However I now have another problem. I believe the following statement works under .NET Framework 4.8:


My.Computer.Keyboard.SendKeys("x{ENTER}", True)

The Microsoft...

With a Console Application with target framework .NET Framework 4.8 a statement of the form


My.Computer.FileSystem.WriteAllText(...)

works fine. But with one with target framework .NET 7.0 I...

Of course! I was creating the project as a Console App, not a Console App (.NET Framework). When I switched to the latter, everything worked fine. Dumb mistake! Thanks all for your help.

Thanks for the suggestion. I tried
Dim text as String = My.computer.clipboard.gettext() and still get an error message,
'computer' is not a member of 'Test.My' (where "Test" is the name of the...

As a very occasional and self-taught programmer, I've written apps under .NET Framework 4.7.2. To use the statement

Dim text as String = Clipboard.GetText()

under that framework it's...

Thanks for the suggestion. The discussion you referred me to mentions that SerialPort.GetPortNames points to HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM. Checking that, I found that indeed it...

I have a soft modem that I access through a vb program. The following code snippet

For Each sp1 In My.Computer.Ports.SerialPortNames
Debug.Print(sp1)

Finally got it! Thanks.

Thanks to you both.

Visual Studio 17.4.2; Framework 4.8.04084

As a newbie to this, I'm hoping one of you could post a code snippet showing how I should proceed. Thanks!!

Imports System.Security.Cryptography
Module Module1
Sub Main()
Dim rng As RandomNumberGenerator = RandomNumberGenerator.Create()
Dim n As Integer = rng.GetInt32(10)

Thanks for your responses. I've found the problem, something I should have checked before. The .wav file I was trying to play is very short - ~50 ms. This plays fine on my desktop, but apparently...

I've written a program in Visual Basic that, among other things, plays a .wav sound file. It works as expected on my desktop computer. When I put the executable on my laptop where Visual Studio is...

Thanks. I'm part-way there. When I add the statement you suggested (using () rather than []) the point color changes from gold to blue, not red. I've added the following test code:

I've created a chart and defined a series as:


Dim series1 As New DataVisualization.Charting.Series
series1.ChartType = DataVisualization.Charting.SeriesChartType.Point

This works but I'd...

Thanks, Amerigoware. I've added your suggestion to my collection of code snippets in case I run into a similar problem. I discovered later in the case I asked about that the problem had nothing to...

Thank you.

I have a vb program that reacts to an event (a signal from a modem) by displaying a form. I have the following (simplified) code:


Public Class MainForm
Dim eventOccurred As Boolean =...

Thanks for the information. I wasn't sure what the difference was in the two calls (not only for Split but for other functions as well). I'll follow your advice.

Yes! Removing "Imports System.String" fixed the problem. I'm actually not sure why I had it there in the first place. Thanks!

Thanks for the reply, but I'm afraid I don't understand. The first version does have two parameters: "ab-c-d" and "-". The second, as I said, was copied directly from an example shown on a...

I have a test line in a VB program:

Dim testArray() As String = Split("ab\c\d", "\")
which I copied more or less straight from a Visual Basic reference.

It works fine in one program, but in...

Done. (BTW, I wanted to rate your replies (high) but I have first to "spread some Reputation around".)

Thanks - that cleared everything up.

Also, I found code tags, for next time.:)

Here is a toy program that illustrates my question:


Public Class Form1
Sub Form1_Load() Handles Me.Load
Dim form2In As String = ""
Form2.Show()
'How do I wait for...

OK, thanks - I finally understand! Thanks everyone for your patience!

Sorry, but I still can't find it.

The only option I see at the top left is the icon "VB". It shows in 3 columns the project name, the form name, and in a dropdown menu, "contextMenu1". But...

Thanks, passel, for your reply.

I suspected that what was meant was just the Visual Studio editor, but I'm still missing something that's probably very obvious.

The Help says "As soon as you...

Very basic question: A Microsoft help page* says,

As soon as you declare a variable using WithEvents, the variable name appears in the left drop-down list of the class's Code Editor.

Right-clicking worked. As you pointed out, jmcilhinney, I should have tried that, but somehow it slipped my senescing mind. Apologies for impelling you to reply.

When I loaded an old project, I got the message "The VB project {name} is targeting ".NETFramework, Version=4.0, which is not installed on this machine. To proceed, select an option below." I chose...

Thanks for the info. I'll use that instead.

Thanks - that fixed it! The only problem was the space between "-" and "jar". The Shell statement now works, though I'm wondering if there is some advantage in using the Process.Start command...

I am trying to run a jar file with a target using: Shell("java - jar {path1}File.jar {path2}TargetFile")

Thanks for the information and the work-around, which solved my problem. As you guessed, the program targets .NET Framework 4.7.2.

Also, I've set the default to Option Strict On. :-)

Microsoft Docs for "String.Contains Method" says an overload is "Contains(String, StringComparison)". Yet when I try

Dim comp As StringComparison = StringComparison.OrdinalIgnoreCase

It appears I must have, even though I didn't think so. I remapped the drives being sure I was *not* an Administrator, and now VB runs under User mode. Thanks.

Thanks for your reply. As I said, I think I've solved the problem by simply running VB as an Administrator. Why that should be necessary I don't know (but there are many things about Windows I...

I finally solved the problem by running Visual Studio as Administrator. I don't know why this is necessary, and if anyone has an explanation I'd be glad to see it!

Thanks - one problem solved. Now for the other one :)
