How to use an Active-X control...

[Zeke]

(VS 2005 Prof)
Please give me some help on how to use an activeX control. I have done the
following:
- created a dll with one class (Utils) which has functions
- imported the ActiveX with tlbimp <dll-path> /out:<cs_dll-path
- added a reference to the new cs dll (Projects, Add reference)
- added a "using" line to the dll.

I can see in intellisense that it is "working". I can also call the unction
which takes no parameters:
Utils ox = new Utils();
string cTest = ox.test();
The string cTest gets the proper value from the ActiveX control

When I try to use a function which takes one parameter I get the following
error:
"No overload method "method_name" which takes '1' arguments

Can you tell me what's lacking - obviuosly there's some difference in how to
use ActiveX functions which takes parameters and which don't.

Any help would be appreciated.

Zeke,

Is there an interface definition that you can use? Something like
_Utils or IUtils? If so, create a variable of that type and then cast "ox"
to that variable. It should expose the methods you are looking for.

Hope this helps.

I tried that, but the result is the same. "No overload method .... takes '1'
argument. It seems that the parameters in the ActiveX control is not
visible - because it works if I call it without parameters. I have tested
the ActiveX in VB6 and there it works fine. Can't figure out what is
missing...

Zeke,

Can you show the class/interface definition, as well as how you are
calling it? Maybe even post the interop assembly and the code you are using
to call it?

Got it! I imported the dll again and the parameters showed up this time.
Probably some update problem.
Thanks.
