I have a function that is exported by a C library with the following signature:
extern "C" BOOL Func()
The function is declared in VB.NET code like this:
<DllImport("mylib.dll", CallingConvention:=CallingConvention.Cdecl)>
Private Shared Function Func() As Boolean
End Function
The problem is that I get an ExecutionEngineException when I call the function from .NET code.
Given that BOOL is typedef'd as int in this C code, should the declaration be different? If so, how should I be declaring this? As Short or Int32? Do I need to marshal the return value?
We are working with an existing native application (most likely written in VB) that loads assemblies and calls methods with "Late Binding." We do NOT have access to its source code. We want to implement this interface in C#, and have the native application call our C# assembly. Is this anything we have to do beyond matching the method names and method signatures to make it work?

Let's say that I have an entire project build in C# and other project build VB and I made a reference to this VB project Because this two projects need to interact between each other. Is this possible? the compiled code of this two project could live together??. Also if i made the same project VB and C# the compiled version are the same??

Lesson: Need to instantiate class before using it,
I'm trying to make a vb.net application that has got 2 textboxes, 7 radio buttons and 2 buttons(one named compile and the other 'run'). How can I load the content of a C/C++(or any programming language) file into the 1st textbox and on clicking the compile button, i should be able to show the errors or the C/C++ program in the 2nd textbox. On clicking Run, I should be able to show the output in the 2nd textbox. In short, I want to use the 2nd textbox as a terminal/console. The radio buttons are 4 selecting the language C or C++ or python or C# or java or perl or vb.Are the compilers of all these languages present in .net? If so how can I call them?
View 2 RepliesI'm working on an application that uses a control with up, down, left and right user bottons to move a box in another control (another form). I know the name of the control. If I place the buttons in the same form, I'm able of keeping the focus on the control that have the box, by using:cvsDisplayControl.focus()
I tried to compile the control with this instruction within the code, but I got a errors since this the display control is not part of the one that has the buttons. Something that can help me is a way to assign tha name of the display control in runtime or read it from a file so the control can be compiled ok.
I've been building tools for ArcGIS. Part of ArcGIS is toolboxes which is basically a collection of tools bundled together. I know how to make toolboxes, but the code I have runs within Arc itself - ie. currently it only runs when you actually start Arc up and run a tool which makes the toolbox.
In theory the code should be able to run outside of Arc and ideally I want it to run at compile time. I know you can run executables as pre and post build events when building the installer so I was thinking I could make it build the toolbox as part of one of these. Catch is, the executable code would need to have access to the compiled files of my project (it needs a link to each tool to build the toolbox) so I can't make the executable in a seperate project. The current project is a class library. Is there a way to run code within my project when building the installer?

View 2 RepliesI have code to deal cards and compile a string list for player and dealer. I want to rank the cards for both player and dealer. I dont know how to compare characters in a string or text (which would give me a starting point).
My Code:
I have a set of classes that mimics enums (see my other questions for specific details/examples). For 90% of my project, I can compile everything in at design time. But the remaining 10% is going to need to be editable w/o re-compiling the project in VS 2010. This remaining 10% will be based on a templated version of my Enums class, but will generate code at runtime, based upon data values sourced in from external configuration files.what my Enums class looks like. The templated fields, per that question, will be the MaxEnums Int32, Names String() array, and Values array, plus each shared implementation of the Enums sub-class (which themselves, represent the Enums that I use elsewhere in my code).I'd like to parse values from a simple text file (INI-style) of key/value pairs:
[Section1]
Enum1=enum_one
Enum2=enum_two
Enum3=enum_three
So that the following code would be generated (and compiled) at runtime (comments/supporting code stripped to reduce question size):
Friend Shared ReadOnly MaxEnums As Int32 = 3
Private Shared ReadOnly _Names As String() = New String() _
{"enum_one", "enum_two", "enum_three"}

I'm certain this would need to be generated in MSIL code, and I know from reading that the two components to look at are CodeDom and Reflection.Emit, but I was wondering if anyone had working examples (or pointers to working examples) versus really long articles. I'm a hands-on learner, so I have to have example code to play with.
