StrPtr, VarPtr and ObjPtr dont anymore exist in VB.Net.Well now the Problem is i need to use it so i used the new way and declared all Functions same:
Public Function VarPtr(ByVal e As Object) As Integer
Dim GC As GCHandle = GCHandle.Alloc(e, GCHandleType.Pinned)
Dim GC2 As Integer = GC.AddrOfPinnedObject.ToInt32[code].....
I want to see if there is a way to do this... I'm Using vs2010 with the WP7 SDK. (VB.NET)
I am declaring this in the global scope.
public objGame as object then say i have classes: Game1 and Game2 for the sake of the example we'll just say both classes have an Update() function
I want to set objGame = Game1 (or Game2) and then be able to call objGame.Update()
What I am trying to do is have a class where the functions of the same name are both instance functions and shared functions.
Public Shared Function Get...(byval xx as xx)
and
Public Function Get...
The Public Function uses a Property xx created in the constructor, whereas the Shared Function has the parameters (byval xx as xx).
The following is a screenshot of the problem: What can I do?
View 3 Replies1) Is it possible to access the Excel mathematical functions without actually opening Excel?
I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?
2) Does anyone know of a MS link or area that gives instruction on "how to" use every function of every Windows DLL at all?
Or for all those that Microsoft have chosen to document online at least.
While converting types, I have found myself using both VB functions and BCL Convert.To* methods.
E.g.)
Cstr() vs. Convert.ToString()
CInt() vs. Convert.ToInt32()
CDbl() vs. Convert.ToInt64()
etc...
Are there any subtle differences that should be noted?
Is there a way to see exactly what the functions are doing. What i mean is there a way to see the class? I know what it does, i just want to know the code.
For example the function: Membership.FindUsersByName()
I'm redoing a program for my company and my boss wanted me to created the entire thing through functions...
For the task I wanted to know is it possible to have functions within functions?
Sort of like in C where we would have nested structures?
Its a FILE I/O, with robot commands, moves and verifications....
So I would find the line in an excel spreadsheet where it moves, the coordinate, put it into an array.
Take the actual results store them into a two dimensional array...etc, etc....
Another function would eventually compare the results with the moves, and within a tolerance.
When you refrence a Function like this one:[code]You may want to be able to get more out of that, like this.[code]So how would I be able to add subs or functions onto a sub or function like that?

Quick background: I have a VB.NET application in which I was previously using ConfigurationSettings.AppSettings to read from app.config, and got an error message to change it to System.Configuration.ConfigurationManager.AppSettings (as the first way is now obsolete)I did so, and I even have a reference to System.Configuration.dll AND the Imports statement at the top, but I am getting a "Name ConfigurationManager not declared" error message. Any suggestions?
CODE:
It's pretty straightforward - I'm just checking if something exists, and if it does, I read from it:
If Not Exists(ConfigurationManager.AppSettings.Get(rep & "Email")) Then
Return False
End If
message = ReadAllText(ConfigurationManager.AppSettings.Get(rep & "Email"))

This is glossed over as an easy thing, but when I try to create the reference by right clicking references and selecting add reference, then going to .net, the system.configuration.dll does not show up in the list. I then did a search for the dll on my system and found it in this location:
C:WINDOWSMicrosoft.NETFrameworkv2.0.50727System.configuration.dll
I then tried to register this DLL using "regsvr32 system.configuration.dll", but I get this error:
----
System.configuration.dll was loaded, but the DLLRegisterServer entrypoint was not found.I also attempted to browse for the file using the add reference utility and it gave me an error stating that a reference to the file could not be added. "This is not a valid assembly or COM component."
I'm really stuck at this point, I can't reinstall .net framework v2.0, the system won't let me. I can't create a reference and I can't get my program to work.
