在DLL里使用图片资源文件出问题了

[zjsyw]

我在做一个软件的时候有几个图片资源（bmp）放在程序里用下面的get_picture（）运行很正常，但是图片太大了，于是我想放到DLL里（dll源程序如下），可是编译过了，调用DLL里的get_picture函数却在 bitmap->LoadFromResourceName((int)HInstance,"SRC1");//这里停住了，下面一句不执行了。哪位朋友帮我看看

#include <windows.h>

// Important note about DLL memory management when your DLL uses the

// any other projects that use the DLL. You will also need to use MEMMGR.LIB
// if any other projects which use the DLL will be performing new or delete

// the file BORLNDMM.DLL should be deployed along with your DLL.
//
// To avoid using BORLNDMM.DLL, pass string information using "char *" or

//
// If your DLL uses the dynamic version of the RTL, you do not need to

#pragma argsused
#pragma resource "source.res" //这是我的资源文件
extern "C" __declspec(dllexport) void __stdcall get_picture();
int WINAPI DllEntryPoint(HINSTANCE hinst, unsigned long reason, void* lpReserved)
{
return 1;
}
//---------------------------------------------------------------------------

void __stdcall get_picture()
{
Graphics::TBitmap *bitmap=new Graphics::TBitmap;
bitmap->LoadFromResourceName((int)HInstance,"SRC1");//这里停住了
bitmap->SaveToFile("c:\\xy_temp.bmp");
delete bitmap;
}

bmp.rc文件如下：

a RT_BITMAP aa.bmp
b RT_BITMAP bb.bmp
c RT_BITMAP cc.bmp

用BCB成成dll文件如下。

//---------------------------------------------------------------------------

#include <windows.h>
//---------------------------------------------------------------------------

#pragma argsused
int WINAPI DllEntryPoint(HINSTANCE hinst, unsigned long reason, void* lpReserved)
{
return 1;
}

把.rc文件加入后编译为dll文件。
//---------------------------------------------------------------------------

//调用如下
#include <vcl.h>
#pragma hdrstop

#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
}
//---------------------------------------------------------------------------

void __fastcall TForm1::Button1Click(TObject *Sender)
{
HINSTANCE h = LoadLibrary("Project1.dll");
TResourceStream *r = new TResourceStream( (int)h, "a", "RT_BITMAP" );
r->SaveToFile("ttt.bmp");
}
//---------------------------------------------------------------------------

把.rc文件加入后编译为dll文件。
rc文件可以直接加入而不需要编译成res资源文件加入吗？怎么加？

[constantine]

project->add to project
读图片的函数不用放到dll里面,dll就放资源就行了

[CACACACACA]

project->add to project加入.rc文件。

然后Project->Builde就生成.dll文件了。
