有关于C2664的错误

Question

 

我用的是VS2005 Express版本，并安装了windows platform SDK for windows server 2003 R2，源程序如下：

#include "Ogre.h"
#include "stdafx.h"
#include "ExampleApplication.h"

class TutorialApplication : public ExampleApplication
{
protected:
public:
    TutorialApplication()
    {
    }

    ~TutorialApplication()
    {
    }
protected:
    void createScene(void)
    {
    }
};

#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
#define WIN32_LEAN_AND_MEAN
#include "windows.h"

INT WINAPI WinMain( HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT )
#else
int main(int argc, char **argv)
#endif
{
    // Create application object
    TutorialApplication app;

    try {
        app.go();
    } catch( Exception& e ) {
#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
        MessageBox( NULL, e.getFullDescription().c_str(), "An exception has occured!", MB_OK | MB_ICONERROR | MB_TASKMODAL);
#else
        fprintf(stderr, "An exception has occured: %s\n",
                e.getFullDescription().c_str());
#endif
    }

    return 0;
}

编译后出现

uments and settings\xjd\my documents\visual studio 2005\projects\test\test\test.cpp(38) : error C2664: 'MessageBoxW' : cannot convert parameter 3 from 'const char ×' to 'LPCWSTR'
1>        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

的错误，我想请教一下该如何解决，谢谢各位。

Answer 2

 

修改成MessageBox( NULL, e.getFullDescription()._TEXT(c_str()), "An exception has occured!", MB_OK | MB_ICONERROR | MB_TASKMODAL);

还是无法通过了，是否修改错误？

Answer 3

MessageBox( NULL, e.getFullDescription().c_str(), _TEXT("An exception has occured!"), MB_OK | MB_ICONERROR | MB_TASKMODAL);

Answer 4

 

谢谢feiyun0112，第3个参数我漏了，但第2个参数的类型还是有同样问题

'MessageBoxW' : cannot convert parameter 2 from 'const char *' to 'LPCWSTR'

Answer 5

MessageBox( NULL,_TEXT( e.getFullDescription().c_str()), _TEXT("An exception has occured!"), MB_OK | MB_ICONERROR | MB_TASKMODAL);

Answer 6

 

谢谢feiyun0112，第3个参数我漏了，但第2个参数的类型还是有同样问题

'MessageBoxW' : cannot convert parameter 2 from 'const char *' to 'LPCWSTR'

Answer 7

 

这样加的_T(e.getFullDescription().c_str()话，会造成Exception对象丢失

error C2065: 'Le' : undeclared identifier

Answer 8

 

解决办法:在工程属性设置页面里,在General选项中,将CharSet设置为Use Multi-Byte Character
