The exception I sent you, I think that the problem is not with the cast, but with the way The method of the com+ object is called...

c is null....how can I use POC

I'm calling the method just like in vb6 the function inside de dll, with the 2 parameters !

OK, Now it worked..

Type objAddType = Type.GetTypeFromProgID("ACEGAC.clsAdmDBConsultas");

//Create Instance

object objConsultas = Activator.CreateInstance(objAddType);

//Make Array of Arguments

object[] myArguments = { 1 };

object c;

c = objAddType.InvokeMember("ConsultarAgendamento", BindingFlags.InvokeMethod, null, objConsultas, myArguments);

MessageBox.Show(c.ToString());

But there is still a problem, how can I make to show the values of the c object...

Like in VB6 it returns a recordset....

Thanks for helping again.

POC I mean to say, you create your own dll in VB (as you do not have access to the current one) and add a test method in that which might return a simple string. Then check if it is able to return the string value in your c# code.. hope you are getting me....

Those articles are not helping you

What is hapening if you create reference of ADODB and typecast your object"c" to that

Hey, I am back again!!!

Have a look at following article

http://www.codeproject.com/csharp/usecomappincs.asp

The late binding section should help.

Excerpt for the article
We have Get IDispatch Interface using Type.GetTypeFromProgID("Project1.Class1")
We have to create instance using the type ID Activator.CreateInstance(objAddType)
We have to make array of arguments (if required)
Invoke the Method using objAddType.InvokeMember function.

I am at work and not having MSN (good that I have access to msdn). And I do not have VB6 too... so I am not able to create dll :-( ......

Are you able to return simple value (not the record set) from the dll in c#

Good Morning!!

Have you able to get the desired results According to you what could be the reason of the exception. You said, it is not about casting, right. Have you able to figureout something.

Fom dll, in vb6 yes, from the C# directly yes...... But from the DLL in vb6 through C# I can't....and for security reasons in the client side I can't connect directly to the database...Damm it...=)

OK,

It gives me this exception "An exception was added by the destiny of a call", lol....I think I'm gonna give up...

Too difficult to do that

objConsultas is null or "c" is null If c is null, are you sure we are invoking the object method properly. Have you tried creating POC and getting the result from your test method

Hughsieman

This is the way I'm using to test... I created my own...And I'm trying to get the result as the original one might do....

Do you have MSN I can send you the files if you want to try...

Or if you can...make a test there.... Create a dll in vb6 to select a value from SQL Server...and return it as string.....test in another vb project...IF it's working try to use the code I post to get it's value...

I think for that you need to typecast/convert object "c" to appropriate type. In your case it is recordset which is getting return.
