困扰了很久得问题

[ruby0602]

POSITION pos = this->GetStartPosition();
HANDLE hFind;
WIN32_FIND_DATA fd;
char strCount[256];
m_ofn.nMaxFile = 256;
m_ofn.lpstrFile = strCount;

m_ofn.lpstrFile[0] = '\0';
while(pos != NULL)
{
CString szNextPath;
szNextPath = GetNextPathName(pos);


多选了以后，为什么szNextPath得不到正确得文件路径？？

[ruby0602]

我得代码不是放在InitInstance（）里得，请大家不要乱套一气，你所说得我都设置过了，请不要光为了分数，不看实际情况

高手帮忙

把你的显示代码发上来看看
是不是你的CString是局部变量，完了后就自动销毁了？
还有，你说不是在INIainstance里的，那难道你自己继承了一个CFileDlg类？

[ruby0602]

void CReplaceDlg::OnMulti()
{

CString szFilePath,szBuffer;
szFilePath = GetPathName();
szBuffer = szFilePath.Left(szFilePath.ReverseFind('\\'));
SetDlgItemText(IDC_EDIT3,szBuffer);
UpdateData(TRUE);
if(m_NewName.IsEmpty()){
AfxMessageBox("请输入新文件名");
}
else
{
// TODO: Add extra validation here
POSITION pos = this->GetStartPosition();
HANDLE hFind;
WIN32_FIND_DATA fd;
char strCount[256];
m_ofn.nMaxFile = 256;
m_ofn.lpstrFile = strCount;

m_ofn.lpstrFile[0] = '\0';
while(pos != NULL)
{
CString szNextPath;
szNextPath = GetNextPathName(pos);


//hFind = ::FindFirstFile((LPCSTR)szNextPath, &fd);

CString szFileName;
szFileName.Empty();
szFileName = (LPCTSTR) &fd.cFileName;
int iLength = szFileName.GetLength();
szFileName.Replace(szFileName.Left(szFileName.GetLength() - 4),m_NewName);

CString strFilePath = szNextPath.Left(szNextPath.GetLength() - iLength);
rename( (LPSTR)(LPCSTR) (szNextPath),
(LPSTR)(LPCSTR)(strFilePath + szFileName) );
//::FindClose (hFind);
}

HWND hDlg=GetSafeHwnd();
HWND hStatusWindow=CreateStatusWindow(WS_CHILD|WS_VISIBLE|WS_BORDER,
TEXT("更名为"),//显示在状态栏上的信息
hDlg, //父窗口句柄
IDS_STATUS);
}


BOOL CReplaceApp::InitInstance()
{
AfxEnableControlContainer();

// Standard initialization
// If you are not using these features and wish to reduce the size
// of your final executable, you should remove from the following
// the specific initialization routines you do not need.

#ifdef _AFXDLL
Enable3dControls(); // Call this when using MFC in a shared DLL
#else
Enable3dControlsStatic(); // Call this when linking to MFC statically
#endif
CReplaceDlg dlg(TRUE,NULL,NULL, OFN_HIDEREADONLY | OFN_ENABLETEMPLATE | OFN_ALLOWMULTISELECT | OFN_EXPLORER,"JPG Files(*.jpg)|*.jpg|GIF Files(*.gif)|*.gif|BMP Files(*.bmp)|*.bmp|(*.*)|*.*||",NULL);

dlg.m_ofn.lpstrTitle = "更改文件名";
dlg.m_ofn.lpstrInitialDir = "g:\\others";
//dlg.m_ofn.Flags |= OFN_HIDEREADONLY | OFN_ENABLETEMPLATE | OFN_ALLOWMULTISELECT | OFN_EXPLORER;
int nResponse = dlg.DoModal();
if (nResponse == IDOK)
{

// TODO: Place code here to handle when the dialog is
// dismissed with OK
}
else if (nResponse == IDCANCEL)
{
// TODO: Place code here to handle when the dialog is
// dismissed with Cancel
}

// Since the dialog has been closed, return FALSE so that we exit the
// application, rather than start the application's message pump.
return FALSE;
}

captain_x(captain) ：请你看看代码，谢谢

256
是不是少点,,
2560
试一下,,我的以前是选几个没有问题,,选多了就会象你一样,,
后来改大了就好了..

[ruby0602]

改成1024也不行，debug了一下，szNextPath老是等于{"\"}

[captain_x]

If the buffer is too small, the function returns FALSE and the CommDlgExtendedError function returns FNERR_BUFFERTOOSMALL. In this case, the first two bytes of the lpstrFile buffer contain the required size, in bytes or characters.
同意楼上的看法，
你用CommDlgExtendedError函数测试一下是不是buffer太小了？

[ruby0602]

我顶啊顶

[captain_x]

呵呵，水平有限，帮不了你了
如果可以的话，把代码发过来，我也研究一下
[e-mail]

[ruby0602]

szNextPath = GetNextPathName(pos);
这句运行完后，pos就突然变为0了，很奇怪啊

[captain_x]

这样好象表明POS已经到最后了

[ruby0602]

我选了好几个文件执行一次就这样了，pos有问题吧？

[ruby0602]

顶到解决为止

[lzf8977]

一顶到底

[ruby0602]

难道没人愿意帮忙吗？

[ruby0602]

你的邮箱？

[ruby0602]

有人说这样定义：
DWORD MAXFILE = 2048;
char strCount[MAXFILE];
m_ofn.nMaxFile = MAXFILE;
m_ofn.lpstrFile = strCount;
m_ofn.lpstrFile[0] = '\0';
但编译通不过，为什么？

[captain_x]

代码发过来看看撒

[captain_x]

上面已经给了，再发一次吧，[e-mail]
