在C++Builder中调用没有被宝兰封装的API怎么办？
我用Delphi调用NetShareAdd,添加网络共享的API（该函数没有被封装），可以正常执行，可再C++Builder中不能运行？我采用的动态调用“netapi32.dll"的方法，编译通过了可是，得不到正确的结果？请大虾指教 问题点数：100、回复次数：6Top

把你的代码贴出来:
函数指针类型的声明;
DLL的装载;
函数指针的获得;
函数的调用.Top

上了你一大当：你明明用的是静态连接！

这两个函数并非没有被BCB封装,你只要Einclude <lm.h>就行了.
在WIN NT和WIN 2K下,这两个函数中用到的所有字符串都是Unicode字符串.
我把你的代码改了一下,现在可以用了:
//NetShare.h:
unsigned int NetShare(WideString ShareName, WideString ShareDir);
unsigned int UnNetShare(WideString ShareName);
//NetShare.cpp:
#include <lm.h>
#include "NetShare.h"
unsigned int UnNetShare(WideString ShareName)
{
return NetShareDel(NULL,ShareName.c_bstr(),0);
}
unsigned int NetShare(WideString ShareName, WideString ShareDir)
{
DWORD Err;
SHARE_INFO_502 si;
LPWSTR ServerName;
ServerName = NULL;
si.shi502_netname = ShareName.c_bstr();
si.shi502_type = STYPE_DISKTREE; // disk drive
si.shi502_remark = NULL;
si.shi502_permissions = 0;
si.shi502_max_uses = -1;
si.shi502_current_uses = 10;
si.shi502_path =ShareDir.c_bstr();
si.shi502_passwd = NULL; // no password
si.shi502_reserved = 0;
si.shi502_security_descriptor = NULL;
unsigned int r=0;
r=NetShareAdd(ServerName,DWORD(2),LPBYTE(&si),&Err);
return r;
}
//调用:
void __fastcall TForm1::Button1Click(TObject *Sender)
{
NetShare("TestE","E:\\DOC");0D
}

我试试，怎么才知道API包含在那个头文件里，需要那个lib，dll？
对于这个函数我能不能用动态调用netapi32.dll,（用Loadlibrary）调用呢？Top

BCB的头文件一般和VC的头文件是一样的(C++标准库和Windows API的头文件是这样的).
在MSDN中,NetShareAdd的帮助的末尾写着呢.
在BCB的Windows SDK帮助的NetShareAdd帮助中也有,点击上面的Quick Info按扭...
