and from VB6 project I reference to Test.dll but an error messege was appear A reference to Test.dll file could not be added (If I create VB NET project and reference to file Test.dll it OK )
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.

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.

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.

Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.

The user can drag an image and drop into the second Panel. All works fine. Now the problem is how can I know the name of the image contained in the PictureBox in the dropped Panel so that I can save it? I tried to recover in a ListBox the name of the images during the population of the first Panel but I don�t know witch may be the reference with the dropped PictureBox.
