VS 2010 Express: Converting Code From VB6 - Error 1 "MsgBox" Not Declared
Mar 7, 2012
When converting the project from VB6 to VB.net. (All links to this classes were deleted: Microsoft.VisualBasic.Compatibility¸ Microsoft.VisualBasic Import System System.Data System.Windows.Form, using Framework 2.0)
I have this errors: Error 1 "MsgBox" not declared. It may not be available due to its protection level....RFrm.vb 1481 9 R
Error 2 "MsgBox" not declared. It may not be available due to its protection level. ...RFrm.vb 1481 135 R
Private Sub _Command4_0Microsoft.VisualBasic.Left_Click(ByVal sender As System.Object,_ByVal e As System.EventArgs) Handles _Command4_0.Click
[CODE]...
And another question, off-topic. Which operators can be replaced with VB.net operators: IsNumeric, Mid, Microsoft.VisualBasic.Left.
The function checks for the input only the digits.
With Text9
If .Text <> "-" And Not IsNumeric(.Text) Then .Text =_
Microsoft.VisualBasic.Left(.Text, .SelectionStart - 1) &_
Mid(.Text, 1 + .SelectionStart)
End With

i was used to be vb 6.0. but now im starting with vb 2010 because 6.0 is old. but now i have a few problems with converting some things for my game that im making.
in 6.0 it was
modPlayer (module)
Public Player(1 To MAX_PLAYERS) as PlayerRec
Private Type PlayerRec
Name as string
Level as string
End Type
but this code gives in 2010 some errors; it says it should be structures right now?
Module modPlayerRec
Public Player(0 To 100) As PlayerRec
Structure PlayerRec
Public Name As String
End Structure
End Module
what should be the right code for vb 2010? this is not working what i have right now.

Are the codes generated from Visual Studio.net 2003 Visual Basic fully convertible and compatible ti Visual Basic 2005 Express Edition ? I tried converting a project which was develop from VS 2003 for VB 2005 but after the process there are some commands which is not supported in the latter version. The deployment module in this project is also not recognised in VB 2005.

I have a code in VB 6 but doesn't in VB.NET. Even I was converting, but, there's a thing that I can't convert because I don't know what "hProcess" means .
Look at the code below:
Quote:
Public Const PROCESS_ALL_ACCESS = &H1F0FFF
Dim f1holder As Integer
Dim timer_pos As Long
[CODE]...
The error says: Name 'hProcess' is not declared.

I am learning VB for the moment. I want to copy/paste code from a PDF to Visual Basic 2010 Exppress, but if i paste the (structured in PDF) code to VB, i get 1 long string of code and need to restructure it by entering after each line. Otherwise VB gives me a lot of errors. This is a time consuming work. Isn't there a way, VB puts the code in the right format?

this is my very first posting and I must say I am desperate. I have a VB assignment due in 2 days and I am so lost. I have written a code to draw some graphic, just a basic house, tree, sun etc. I have also written a code to magnify said graphics which were all the specifications of my Assignment 1 part A. Now for Part B I am being asked to extend my program so that: A - My graphic can be drawn using different colour schemes designed by me but chosen by the user B - My graphic or an appropriate part of it can be animated around the picture box if the user chooses to do so. C - Error checking is included.

I recently downloaded the Windows API code pack for .net, and seeing there was VB.net examples inside there, I opened them up. Upon building I get a warning that the referenced components 'Core' and 'Shell' could not be found. Looking in the code pack folder I see there are no DLLs at all, but instead a whole load of C# sources.
Do I have to download C# Express (which I want to avoid) to use the code pack or are there precompiled DLLs somewhere?

I used the following code(with bug):
Code:
For n = 0 To 100
If saveLine(n).Substring(0, 8) = "heading:" Then
cboSelect.Items.Add(saveLine(n).Substring(8))
End If
Next n
The For loop only ran 5 times. It turned out that saveline(5) was shorter then 8 characters, so I changed the code which solved the problem:
Code:
For n = 0 To 100
If saveLine(n).Length > 8 Then
[code]....
VB 2010 neatly exits the for loop when the bug occurs. In this case it was easy for me to pick up the bug, because the combo box was not properly populated. What if it was not obvious that the for loop did not complete? It is quite scary to think that bugs like this are not displayed at run time.

I want to test out a code line with about 50,000 characters over about 7 lines, but VB takes about 2-3 minute breaks for every line of code I change and it crashes every 1-5th try. I moved the code into a public shared sub in a new class, and closed the class tab, but still VB can't resist checking though the code all the time.Is there any way I can prevent VB from checking that class/code?

I've just installed Visual Studio 2010 Express on a new laptop running Windows 7 64 bit.
When I debug a VB project and an error is encountered a message is sent to the immediate window, but execution is not halted. This means I am unable to look at variables etc.

I am getting the following compilation errors from Microsoft Visual Basic 2010 Express on the first line of my code:
Error 1 Newline in constant C: cdotnetdevsrcvbmain estHelper.vb 1 1 Component Sources
Error 2 Too many characters in character literal C: cdotnetdevsrcvbmainRtestHelper.vb 1 1 Component Sources
The first line of my code is simply:
' Copyright 2011
It is generating the same compilation error for all my comments. Does anyone know why MS VB Express 2010 is acting this weird? Comments in visual basic are supposed to start with a single apostrophe so I don't understand this weird behavior.

I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.
