DispatchEntry DispatchTable - Converting C++ to C#

[jwgoerlich]

Hello group,

How would one write the following C++ code in C#? What .Net object
could I use for a DispatchEntry?

DispatchEntry DispatchTable[] = {
{ TEXT("classfilter"), cmdClassFilter, MSG_CLASSFILTER_SHORT,
MSG_CLASSFILTER_LONG },
{ TEXT("classes"), cmdClasses, MSG_CLASSES_SHORT,
MSG_CLASSES_LONG },
{ NULL,NULL }
};

Thanks,

J Wolfgang Goerlich

I can't find anything in MSDN as to what that is.

However, if I had to guess, it is some sort of command framework, which
..NET doesn't have an equivalent for (at least in Windows Forms, with WPF,
there is a command infrastructure). You would have to write something
yourself in this case.

Makes sense. The second parameter (cmd*) is pointing to a method. The
procedures that call this use it to pass control to other procedures.
I can create something similiar using a struct and an array. What
object type should I use to represent the method, though?

private struct DispatchEntry
{
public string cmdString;
public ????? memberProcedure;
public uint shortHelp;
public uint longHelp;

public DispatchEntry(string command, ????? procedure, uint help1,
uint help2)
{
cmdString = command;
memberProcedure = Function;
shortHelp = help1;
longHelp = help2;
}

}

DispatchEntry[] DispatchTable = {
new DispatchEntry("classfilter", cmdClassFilter,
MSG_CLASSFILTER_SHORT, MSG_CLASSFILTER_LONG),
new DispatchEntry("classes", cmdClasses, MSG_CLASSES_SHORT,
MSG_CLASSES_LONG),
new DispatchEntry("disable", cmdDisable, MSG_DISABLE_SHORT,
MSG_DISABLE_LONG)
}

?????? = delegate

?????? = delegate

Is there more to it? The following code results in an "Identifier
expected" compiler error.

private struct DispatchEntry
{
public string cmdString;
public delegate memberProcedure;
public uint shortHelp;
public uint longHelp;
}

public delegate memberProcedure;
public uint shortHelp;
public uint longHelp;
}

It depends on the method signature, here is a sample:

delegate void SomeMethod();

I'm not relly clear on what you are trying to achieve with this structure,
is this to be used in an interop scenario or what?

Thank you, I will play around with delegate some more.

I am converting existing C++ code. It looks up the functions in this
table and uses that to pass control from one member to another.
