I am receiving this error: Reference to a non-shared member requires an object reference on the code I've
bolded within the code body. Here is my code:
[Code]...
I get this error:Reference to a non-shared member requires an object reference.When i compile on the following code section:
Private Sub statusBarToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs)
ToolStripMenuItem.Checked = Not ToolStripMenuItem.Checked
statusStrip1.Visible = ToolStripMenuItem.Checked
when I do something like this: Process.Start [URL] it says that error only on Form2 not Form1.

View 2 RepliesI am opening frmB (variable for FormB - the actual form) from frmA. From btn1 I open frmB like this:
frmB = New FormB()
frmB.Show()
From btn2 (frmB is already open) I bring frmB to the front from behind frmA:
FormB.Show()
FormB.BringToFront().
No problem so far. Now I need to pass an arg to frmB. This is where I am having the problem.
from btn1 (in frmA) I do this:
frmB = New FormB(myArg) '--pass myArg to constructor of FormB -- no problem here
frmB.Show()
then from btn2 -- this is where I have the problem
FormB.Show()
FormB.BringToFront()
I tried placing myArg in FormB.Show(myArg) but that did not fix the problem. What is the correct way to pass myArg to FormB (frmB) in this scenario? Do I need to share FormB or frmB? How do I do this? "frmB" is frmA level variable.

View 5 RepliesBecause I rush in development (a lot of whip cracking here) and declare my objects at the top of the function and instantiate inside my try-catch block, I get a lot of the good old "object not set to an instance of an object" errors while doing TDD, and later if I do miss a branch that object was used in (doing VB now, would prefer C#) or just in every day coding,object not set to an instance of an object is a bit vague. Sure the stack trace sends me to the line the error occured at, but it would be nice if I could modify my logging to either name the object or its type because sometimes I have multiple objects on the same line. It's not the end of the world, but in the end it would save me a few minutes each day. how I can pass the info on which object wasn't set?
View 1 RepliesI am running W7 32 bit ultimate with net 2010 development I have an app I want to distribute which works fine on XP & W7 32 bit, but fails on being installed on W7 64 bit, I believe, although not 100% certain the error I am getting: "Unknown Cause; 3706 > Application-Defined or Object-defined error" is related
to ADO
Whilst I have no need to fix my own W7, how do I incorporate in the distributed msi, whatever is required for 64 bit if that is the problem. Or what Instructions are need on the users W7 64 bit pc to resolve this?
In my program i have added a reference to Windows Script Host Object Model to make a shortcut. I then used "Imports IWshRuntimeLibrary".My problem is that when i run the program i get an error meaage saying "Could not load file or assembly 'Interop.IwshRuntimeLibrary, Version=1.0.0.0, Culture= neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified." This only happens when i run the program outside of VS 2005, when i press start debugging is VS it works fine.

I'm trying to learn how to call functions in C DLLs from Visual Basic programs. I'm new to VB but have years of experience in C programming & want my functions to be usable by people who are more familiar with VB.
I managed to create a C DLL & call the functions from a C program. One difficulty I had was that I wanted to put my DLLs in a MyExes directory so I could easily have several unrelated programs call them. It was far from obvious how to tell the compiler & linker to look for the DLL in some arbitrary folder but I eventually found out.
[URL]
Now one of my difficulties with DLLs & Visual Basic is how to tell Visual Basic 2010 Express to look for functions in a DLL in some arbitrary folder. I tried to use Project->Add Reference, then in the Browse tab went to the folder & DLL I wanted to use, but got the message box:"A reference to C:ProgramFilesMyExes....dll could not be added. Please make sure that the file is accesible and that it is a valid assembly or COM component."I've tried to find a walkthrough to take me through the steps of using C DLLs in VB 2010, but so far had no luck.
how I can get rid of this error?

If you delete some of these two functions the error doesn't appears. This problem is not present in Visual Studio 2008 or 2005.
Friend WithEvents ResultsTable1 As Results_Table.ResultsTable In the automatic form generation code bloc.Referenced results table has a new function as Public Sub New_ ResultsTable(ByVal IsLive As Boolean, ByVal Mode As Short, ByVal NumStuff As Short, ByVal KeyName As String, ByVal strDate As String, ByVal strTime As String, ByVal strDB As String)[code]And I'm generating a Object not set to an instance of an object.Unfortunatly it won't let me just do something dirty like"Dim a As New Results_Table" because it says it is already there due to the friends with nonsense.
