I would like to do something like the following:
Public Class Form1
Public Event Evt1(ByVal c As c1)
Public Event Evt2(ByVal c As c2)
[code]...
However, it seems to be invalid syntax, as the signature of OnEvt1OrEvt2 doesn't match that of Evt2.
Edit: The above code seems to work fine for everyone but me, but it doesn't compile for me in VS2005 SP1.The error message is something like:Error BC31029: The method 'Private Sub OnEvt1OrEvt2(c As WindowsApplication1.c1)' can not handle the event 'Public Event Evt2(c As WindowsApplication1.c2)' because the signatures do not match.

I'm planning on using the Smart Device Framework 2.3 to use the signature control panel in a Windows Mobile 5 application using the compact framework 3.5.
The control has the option to save the signature as either a byte array of points, or as a bitmap. Now seeing as I want to store the signature in a sql compact database, I guess the byte array is going to be better. The trouble is, I'm not sure how to render that in a full WinForms application after I've transferred it back to the desktop.
I need to show the signature on a report, so it would need to be an image I could link/embed into the report.

Why does this:Private [Function] As Func(Of Double, String) = Function(ByRef z As Double) z.ToString
gives the following error:Nested function does not have a signature that is compatible with delegate String)'.
While this:Private [Function] As Func(Of Double, String) = Function(ByVal z As Double) z.ToString
Does not? (The difference is ByRef/ByVal)
Furthermore, how might I implement such a thing?

I've an issue regarding p/invoke from managed to unmanaged code. See my original post at the MSDN forum (as brief summary is seen later in this post). Before I go on, I just want to explain a couple of things: I have a wrapper assembly in net 3.5 that does the actual interop to the unmanaged code. Then I have my console "host app" which uses the wrapper assembly. The solution I came up (I refer to my MSDN post) works when the host app is using .net 4, but it doesn't work when changing the host app to use .net 3.5. When changing, I get a AccessViolationException.
host app: 4.0, wrapper assembly: 3.5
-> works
host app: 3.5, wrapper assembly: 3.5 -> throws
AccessViolationException
Do anyone have a clue to why I get an AccessViolationException? Most importantly, how do I get it working with .net 3.5?
Brief summary on the MSDN post I refered to. I have this messy p/Invoke I need to solve. The C declaration looks like this:
long TBAPI TbeAndring (short,
short,
PTB_PU,
PTB_ANDRING_INFO,
PTB_PARAMS,
[CODE]...
Where PTB means that each argument is a struct pointer to an array of arbitrary length. The structs mostly contains strings, doubles, char and short. Anyway, I ended up with this DllImport statement:
<DllImport(NativeLibraryName, CallingConvention:=CallingConvention.StdCall, CharSet:=CharSet.Ansi, SetLastError:=True)>
Public Shared Function TbeAndring(ByVal sAntMoment As Short, _
ByVal sAntPU As Short, _
[CODE]...
As you see some of the arguments are changed by the unmanaged code as well.

I'm really struggling with the following pinvoke call. I've tried numerous different ways of doing this but still no joy. The call runs through, but I get a 'Bad parameter' message back with suggests there is something wrong with the struct, since I've ran through a c++ example of this code and the parameters are all correct.

Looking at Microsoft's page on Wow64DisableWow64FsRedirection, I see some C code. What if you want to call this function and it's revert from VB.net? So far I have done this:
<Runtime.InteropServices.DllImport("KERNEL32.DLL", EntryPoint:="Wow64DisableWow64FsRedirection")> _
Public Shared Function DisableWow64Redirection() As Boolean
End Function
And I do likewise for the Revert brother function.This seems to work, as the shell command I call after actually finds its exe in system32, but I am not sure about the Revert, does it need a parameter? This Revert page seems to want me to take the output from disable and plug it into the revert call. Does that sound right? How do I change my DLLimport to take in a boolean and actually use it in the Kernal32.DLL function?

I am running Visual Studio 2005 (I tried 2008 and got the same error) using SQLite for a device project. (Windows 6 Mobile)The identical code works perfectly for Windows, but when I execute
f.FileName = PathForDB
SQLconnect.ConnectionString = "Data Source=" & f.FileName & ";"
SQLconnect.Open()
I get the above message. I have tried to "manually" load the DLL at the beginning of my code, but I still get the same message.

I want to enable the 'ReaderMode' for paning/scrolling my control in .Net. Closest thing I found was this Win API function .url....However, I'm not sure how to call this one, in the documentation it says, This function is not declared in any public header. To use it, you must access it as ordinal 383 from Comctl32.dll.I've never called a function that didn't have a name before, can anyone describe how to do this in VB.Net?

I'm using PInvoke to access some routines from a third party library, however i'm getting SEHExceptions when trying to use callbacks defined for one particular method. The callbacks are used to provide feedback from other unmanaged methods within the third party library, passing a string back to the calling application containing a status message.

I've got a dll, written in C++ (which I have the source code for and have compiled it under VS2010)It has a function I want to call in VB
SHARED_FUNCTION int yasdiMasterInitialize(const char * iniFile,DWORD * pDriverNum );
I've declared it as follows:
<DllImport("yasdimaster.dll")> Public Function yasdiMasterInitialize(ByRef IniFile As String, ByRef DriverNum As UInt32) As Integer
End Function
as when I try and use it as follows I get a pInvoke error:
Console.WriteLine("Initialise:" & yasdiMasterInitialize("yasd.ini", Drivers))
From reading around this is something to do with the declaration but I don't know what to change as this is the first time I've tried calling a DLL.
