I connected to the Informix server using RazorSQL, created a stored procedure and tested it, getting the expected answer, so the procedure exists in the database in some form.
I then run the following code:
If ConnectToInformix() Then
Dim cmd As New IfxCommand("dc_routeHasOutstandingQuantity", conn)
cmd.CommandType = CommandType.StoredProcedure
[Code]....
This error does not occur when calling the stored procedure from a live SQL connection.
I want to create an ExpressionTree where a Func(of Vector, Vector, Vector, Vector, Double, Double, Vektor) should be called. So I use
Expression.Call(Forces(0).Function.Method, {Vec1, Vec2, Vec3, Vec4, Double1, Double2})(Vec1-4, Double1-2 are declared as ParameterExpression and Forces(0).Function as Func(of Vector, Vector, Vector, Vector, Double, Double, Vector). But I get an AgrumentException, because Forces(0).Function.Method has seven Arguments. (System.Runtime.CompilerServices.Closure as seventh argument at Index 0).

View 5 RepliesDLLs in .net are treated differently than in C++ and other programming languages.When you create a class library project in VS (for either VB or C#) you are creating a DLL. In order to call/use that DLL in another project you have to add a reference to your new program.Go to Project > Add Reference..., or right-click on the project that needs to use your DLL, and click "Add Reference...".
After a short wait you should see an Add Reference dialog box.There are several tabs across the top but each of the components that is listed in a tab represents a DLL. If you expand the "Path" column in the .Net tab you will see the DLL location.If your two projects are in the same solution, you should probably go to the Projects tab and add the project that you need.If your dll project is NOT in the same solution as your project that needs to use the dll, then go to the Browse tab and find your compiled DLL from your DLL project. This will add the DLL as a reference to your solution.
Okay, this is my first newbie question so I'm sorry for this newbie question.I've look at Toolbox and I just can't find whatever this called.I don't even know what the name of it too so if anyone know what this called,

View 1 RepliesI have created a new Class Library in visual basic and called it 'TestDLL'. I have a TestDLL.vb file where I put in this code
Class TestDLL
Function ReturnHello() As String
Return "Hello"
End Function
End Class
Then I clicked on the build tab and built the solution. I then copied the DLL 'TestDLL.dll' to C:TestDLL.dll
I am trying to use that DLL in a console application. I have tried this code but I get an error: System.EntryPointNotFoundException was unhandled Message=Unable to find an entry point named 'ReturnHello' in DLL 'C:TestDLL.dll'.
Declare Function ReturnHello Lib "C:TestDLL.dll" () As String I have added TestDLL.dll to the references for the console application and got that to work, however my goal is to load and unload different .dll files without restarting the application. I have a lot more code besides this, but I'm just trying to find out what commands I could use for just calling functions from DLL files.
There was something I was reading about assemblies, but all I get that to do is list the classes in my dll file. I will already know all the names and locations of the .dll files, and also the class and functions that they contain, because I will be building all of them. how I can get a simple function return in my console application.

I'm making a button via images, which changes appearance as the user uses the mouse. For example, when the user clicks on the button, the image changes into the button being "pushed in." My problem is that when the user presses the button and releases the mouse I want it to go back to the image when the user is just hovering over the button. This only happens if the cursor is move off the button and then moved back onto it. I'm trying to call the event/sub where the mousehover event is used in order to get it to change back to the desired image. How do I call this event and/or sub in order for it to work?
