win2k下的程序不能在98下使用？

[balloy]

我有一个程序，目的是判断出操作系统的版本，2000下运行是正常的，但在98下，却一执行就出错：请各位大侠帮我看看原因，源代码如下：

#include <windows.h>

LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;

BOOL Is_Win2000_Professional();

PTSTR GetWindowsVersion()
{
OSVERSIONINFOEX osvi;
BOOL bOsVersionInfoEx;

// Try calling GetVersionEx using the OSVERSIONINFOEX structure.
//
// If that fails, try using the OSVERSIONINFO structure.

ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);

if( !(bOsVersionInfoEx = GetVersionEx ((OSVERSIONINFO *) &osvi)) )
{
// If OSVERSIONINFOEX doesn't work, try OSVERSIONINFO.
osvi.dwOSVersionInfoSize = sizeof (OSVERSIONINFO);
if (! GetVersionEx ( (OSVERSIONINFO *) &osvi) )
return TEXT("ERROR");
}

switch (osvi.dwPlatformId)
{
case VER_PLATFORM_WIN32_NT:

if ( osvi.dwMajorVersion <= 4 )
return TEXT("WINNT4");

if ( osvi.dwMajorVersion == 5 && osvi.dwMinorVersion == 0 )
{
if (Is_Win2000_Professional())
return TEXT("WIN2000PRO");
else
return TEXT("WIN2000SRV");
}

break;

case VER_PLATFORM_WIN32_WINDOWS:

if (osvi.dwMajorVersion == 4 && osvi.dwMinorVersion == 0)
return TEXT("WIN95");
if (osvi.dwMajorVersion == 4 && osvi.dwMinorVersion == 10)
return TEXT("WIN98");
if (osvi.dwMajorVersion == 4 && osvi.dwMinorVersion == 90)
return TEXT("WINME");

break;

}

return TEXT("WINXP");
}


//就是这个函数会报错，但奇怪的是98下并不会执行此函数
BOOL Is_Win2000_Professional()
{
// MessageBox(NULL, "Is_Win2000_Professional", "a", MB_OK);

OSVERSIONINFOEX osvi;
DWORDLONG dwlConditionMask = 0;

// Initialize the OSVERSIONINFOEX structure.

ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
osvi.dwMajorVersion = 5;
osvi.wProductType = VER_NT_WORKSTATION;

// Initialize the condition mask.

VER_SET_CONDITION( dwlConditionMask, VER_MAJORVERSION, VER_GREATER_EQUAL );
VER_SET_CONDITION( dwlConditionMask, VER_PRODUCT_TYPE, VER_EQUAL );

// Perform the test.

return VerifyVersionInfo( &osvi, VER_MAJORVERSION | VER_PRODUCT_TYPE, dwlConditionMask);

}


int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
PSTR szCmdLine, int iCmdShow)
{
static TCHAR szAppName[] = TEXT ("test") ;
HWND hwnd ;
MSG msg ;
WNDCLASS wndclass ;

wndclass.style = CS_HREDRAW | CS_VREDRAW ;
wndclass.lpfnWndProc = WndProc ;
wndclass.cbClsExtra = 0 ;
wndclass.cbWndExtra = 0 ;
wndclass.hInstance = hInstance ;
wndclass.hIcon = LoadIcon (NULL, IDI_APPLICATION) ;
wndclass.hCursor = LoadCursor (NULL, IDC_ARROW) ;
wndclass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH) ;
wndclass.lpszMenuName = NULL ;
wndclass.lpszClassName = szAppName ;

if (!RegisterClass (&wndclass))
{
MessageBox (NULL, TEXT ("This program requires Windows NT!"),
szAppName, MB_ICONERROR) ;
return 0 ;
}

hwnd = CreateWindow (szAppName, szAppName, WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
NULL, NULL, hInstance, NULL) ;

ShowWindow (hwnd, iCmdShow) ;
UpdateWindow (hwnd) ;

while (GetMessage (&msg, NULL, 0, 0))
{
TranslateMessage (&msg) ;
DispatchMessage (&msg) ;
}
return msg.wParam ;
}

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
HDC hdc ;
PAINTSTRUCT ps;
RECT rect;

switch (message)
{

case WM_PAINT:
hdc = BeginPaint(hwnd, &ps);
GetClientRect(hwnd, &rect);


TextOut(hdc, 0, 0, GetWindowsVersion(), 10);

EndPaint(hwnd, &ps);
return 0;

case WM_DESTROY:
PostQuitMessage (0) ;
return 0 ;
}
return DefWindowProc (hwnd, message, wParam, lParam) ;
}

谢谢大家！

case VER_PLATFORM_WIN32_NT:

if ( osvi.dwMajorVersion <= 4 )
return TEXT("WINNT4");
break;//add break here

这样的确不会错了，但这样又无法判断到底是win2kprofessional还是win2kserver了

[zhuwenzheng]

在98下当然不会判断是win2kprofessional还是win2kserver，只有在2000的情况下才判断，判断不出是win2kprofessional还是win2kserver，肯定是你的程序问题

[balloy]

我的意思是我的这个程序编译一遍，希望能够在不同的操作系统下使用（否则还有什么意义？）
但如果这样：
case VER_PLATFORM_WIN32_NT:

if ( osvi.dwMajorVersion <= 4 )
return TEXT("WINNT4");
break;//add break here

此程序在win2k下运行就判断不出到底是win2kprofessional还是win2kserver，而没有这个break;的话，在win98下运行就会出错

[zhuwenzheng]

case VER_PLATFORM_WIN32_NT:

if ( osvi.dwMajorVersion <= 4 )
return TEXT("WINNT4");
else if ( osvi.dwMajorVersion == 5 && osvi.dwMinorVersion == 0 )
{
if (Is_Win2000_Professional())
return TEXT("WIN2000PRO");
else
return TEXT("WIN2000SRV");
}

很遗憾，还是不行，唉，这个问题真是古怪，我添加了测试代码：
if ( osvi.dwMajorVersion <= 4 )
return TEXT("WINNT4");

MessageBox(NULL, "WIN2000", "a", MB_OK);
return TEXT("WIN2000");
并把剩余的语句注释，98下就可以执行了，但决不会弹出对话框，这是符合设想的。但一旦把注释取消，98下运行立即就会报错，这到底是怎么回事

[balloy]

这样也还是不行啊，我的程序你收到了吗？

[zhuwenzheng]

我收到了，但是我的winbase.h中的OSVERSIONINFOEX 没有VER_NT_WORKSTATION等等，估计我的需要更新了，我看了程序，在WIN2000下编译的话应该没有问题，然后你在WIN 98 下运行试试
对了，那里可以DOWNLOAD E文的VC升级包

[balloy]

我的就是在win2k下编译成功，并运行成功，但在win98下运行失败的

vc升级包我不知道哪儿有，我以前倒是down过一个visual studio6的升级包，大概150M，是在微软down的，不知道你要的是不是那个。

[balloy]

这个问题难道没有解决办法吗？

[balloy]

算了，散分把
