最近在研究用C生成.dll，在LV调用，但是在做到字符串数组中不知道为什么总是不成功，下面是在VC下的代码 麻烦版主帮看看，谢谢 // test.cpp : Defines the entry point for the DLL application.
// #include "stdafx.h"
#include "extcode.h"
#include "string.h" BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
return TRUE;
} typedef struct
{
int dimSize;
LStrHandle array;
} TD1;
typedef TD1 **TD1Hdl; extern"C"__declspec(dllexport) void LVArrayChar(TD1Hdl output); extern"C"__declspec(dllexport) void LVArrayChar(TD1Hdl output)
{
NumericArrayResize(uB,1L,(UHandle *)&(*(*output) ->array), 100);
(*output) -> dimSize = 100;
strcpy((char*)(*(*output) -> array) ->str,"abcd");
(*(*output) -> array) -> cnt = 100;
