请看我这样使用GetOpenFileName为何会非法操作

[netxray]

BOOL boolRtn;
LPOPENFILENAME lpofn;
//char szFile[260];
unsigned short *szFile=new unsigned short[260];
memset(&lpofn, 0, sizeof(OPENFILENAME));
CString strFilter("*.*");
CString strTitle("*.*");
lpofn->lStructSize = sizeof(OPENFILENAME);
lpofn->hwndOwner = NULL;
lpofn->lpstrFilter = strFilter;
lpofn->lpstrCustomFilter = NULL;
lpofn->nFilterIndex = 1;
lpofn->lpstrFile = szFile;
lpofn->nMaxFile = sizeof(szFile);
lpofn->lpstrFileTitle = NULL;
lpofn->nMaxFileTitle = 0;
lpofn->lpstrInitialDir = NULL;
lpofn->lpstrTitle = strTitle;
lpofn->lpstrDefExt = NULL;
lpofn->Flags = OFN_HIDEREADONLY | OFN_FILEMUSTEXIST;
boolRtn=GetOpenFileName(lpofn);

没搞错吧，lpofn什么时候分配了内存！！

另外，
unsigned short *szFile=new unsigned short[260];

sizeof(szFile) = 1知道吧，下面这样用吧。

BOOL boolRtn;
OPENFILENAME ofn;
char szFile[260];
memset(&ofn, 0, sizeof(OPENFILENAME));
CString strFilter("*.*");
CString strTitle("*.*");
ofn.lStructSize = sizeof(OPENFILENAME);
ofn.hwndOwner = NULL;
ofn.lpstrFilter = strFilter;
ofn.lpstrCustomFilter = NULL;
ofn.nFilterIndex = 1;
ofn.lpstrFile = szFile;
ofn.nMaxFile = sizeof(szFile);
ofn.lpstrFileTitle = NULL;
ofn.nMaxFileTitle = 0;
ofn.lpstrInitialDir = NULL;
ofn.lpstrTitle = strTitle;
ofn.lpstrDefExt = NULL;
ofn.Flags = OFN_HIDEREADONLY | OFN_FILEMUSTEXIST;
boolRtn=GetOpenFileName(&ofn);

我知道了,以后抄msdn不能自作聪明的瞎改,呵呵
感谢!
