VS 2008 分割窗体视图断言错误

[chentao1206]

VC6.0的项目，迁移到VS2008上，创建窗体分割视图时，出现断言错误！VC6.0上能正常运行，没有问题
大家帮忙看下是啥问题，谢谢了

崩溃的时候在弹出的对话框按相应按钮进入调试，按Alt+7键查看Call Stack里面从上到下列出的对应从里层到外层的函数调用历史。双击某一行可将光标定位到此次调用的源代码或汇编指令处。

已经解决了！SystemParametersInfo ( SPI_GETNONCLIENTMETRICS... 在VC 2008 里不能正常工作 NONCLIENTMETRICS ncms = {0} ; ncms.cbSize = sizeof(NONCLIENTMETRICS); int s = sizeof(NONCLIENTMETRICS); BOOL b = SystemParametersInfo (SPI_GETNONCLIENTMETRICS, (int)&s, &ncms, 0); DWORD dw = GetLastError(); 上面这段代码在VC 6.0 中工作正常,但是在VC 2008 里 SystemParametersInfo 返回 0,而 GetLastError 返回的却是 0 简单订正如下: ncms.cbSize = sizeof(NONCLIENTMETRICS) - sizeof(ncms.iPaddedBorderWidth); 实际是由于从 Vista 和 Windows Server 2008 开始 NONCLIENTMETRICS 在最后增加了iPaddedBorderWidth字段,如果你的程序打算同时支持 vista 或 XP ,Windows 2000, Windows Server 2003,那么应该先调用 GetVersionEx 检测Windows版本,然后决定是否需要减去 sizeof (ncms.iPaddedBorderWidth) ; 大家可以参考下这http://blog.csdn.net/qsycn/article/details/4790059
