从vb.net调用VC ++ dll的函数 [英] Calling a VC++ dll's function from vb.net

问题描述

我有一个VC ++ dll，用于为我们的应用程序创建GUID.
VC ++函数如下所示.该dll的名称为GUIDDll.dll.用来调用的函数是"metodo".

Hi,

I am having a VC++ dll which is used to create GUID for our application.
The VC++ funciton is given below. The name of the dll is GUIDDll.dll. The function used to call is "metodo".

CString metodo(CString &strGUID,short ID)
{
    ACNCreateNewGUID(strGUID,ID);
    return strGUID;
}

输入参数是ID，输出参数是strGUID.谁能告诉我如何从vb.net调用函数"metodo".如果可能，请分享给我示例代码片段以调用该函数.

当我尝试调用此函数时，它将引发错误无法找到DLL GUIDDll.dll的入口点".

谢谢，
Sivakumar.M.

The input parameter is ID and the output parameter is strGUID. Can anyone please tell me how to call the function "metodo" from vb.net. If possible, please share me sample code snippet to call the function.

When I am trying to call this function, it is throwing an error "Unable to find out the entry point of the dll GUIDDll.dll".

Thanks,
