How do I access functions in an OCX?

[Bob Bouthillier]

Hello,

I created an OCX file in C++. It contains a couple of functions each of which have arguments and return values.

After registering the OCX and putting it on the ToolBox in VB6....what must I do to be able to use the functions?

I have tried the following:
Dim Var1 As MyFunctLib.Myfunct

where Var1 is a new label
MyFunctLib is the name of the ocx library
Myfunct is the name of the OCX "Toolbox object"

Then I added the following line...
Var2 = Var1.GetData(1)

where Var2 is a new variable
GetData(1) is a function in the Myfunct Object

In this example, the C function I am accessing looks like this:
short GetData(short VarName)
{
if(VarName == 1)
return(1)
else
return(0)
}


Question: Is there something I need to do to "Reference" the object in the VB project before using it?

I cannot find any examples showing the implementation of an OCX function with parameters in VB. Any help is appreciated

Thanks Much!

I'm not sure, but isn't an OCX an ActiveX control? I think what you need is a DLL.

Well, yes.

If you've created your function inside the Usercontrol and declared it Public, then you can use:

var = userctlname.FunctionName(Params)

AFTER you've added the usercontrol to your form.

OR, you can find yourcontrolname in the REFERENCES, or BROWSE for it.

I agree with dsy5, using a AXDLL is MUCH easier.

Thanks for the advice to pursue it as a AXDLL.

I've now created a dll with automation and put the same function into it. However, since I'm a C/C++ programmer, and not a VB programmer, I don't know how to properly declare the function and use it in VB6.

Can anyone help with this?

Thanks.
