How to use msvbvm60.dll exported functions directly in NON-VB6 languages

[avyan]

Hello trick,

I know how to call exports from msvbvm60.dll using vb6 applications by defining these exports in activex dll or standard dll from the examples in your code bank http://www.vbforums.com/search.php?d...&childforums=1.

How to use msvbvm60.dll exported functions in NON-VB6 languages directly for example in c/c++ without the need for vb6 application.

The following code for export rtcSin succeeds.

#include <windows.h>
#include <stdio.h>
 
typedef double (WINAPI *rtcdouble)(double);
 
int main()
{
    HMODULE hModule;
    rtcdouble rtcSin;
    double result;
    
    printf("rtcSin Example\n\n");
 
    hModule=LoadLibrary("msvbvm60.dll");
    rtcSin=(rtcdouble)GetProcAddress(hModule,"rtcSin");
 
    result=rtcSin(1.57);
    printf("Sin(pi/2)=%lf\n", result);
 
    return 0;
}

But if I use the same for export rtcInputBox etc it fails.
Is there any generic way to call msvbvm60.dll any exported functions directly in c/c++ without fail for which I thank you.

Hello trick,

After loading MSVBVM60.dll using LoadLibrary
can we create VB.Global object in the c/c++
using CoCreateInstance so that I can run rtcInputBox API of MSVBVM60.dll.

HINSIANCE HMSVBVM=LoadLibrary("msvbvm60.dll");//fine

//From HMSVBVM Create VB.Global object using CoCreateInstance  //How

//call rtcInputBox  //fine

How can we create VB.Global object using HMSVBVM .

Maybe try CreateIExprSrvObj and CoInitialize like when you initialize the runtime in a new thread in VB6?

Anyway, it's clear you're smkperu/jsvenu, so why the new alias?

Hello fafalone,

Already tried does'nt work unless you create a vb6 activex dll object using CoCreateInstance.
In order to avoid using vb6 exe I wanted to directly get VB.Global object from msvbvm60.dll and use CoCreateInstance to instantiate
it in my c/c++ code.

You're right. Closed.
