我正在使用以下功能..而不是CFolderDialog ..来获取文件夹路径...在下面检查我的代码.... am当我尝试在编辑框中打印文件夹路径名时遇到运行时错误。

void
CSelfExtractorUIDlg::OnBnClickedButton1()
{

CDialog dlg;

HWND hwnd = NULL; LPCTSTR szCurrent =
(LPCTSTR)malloc(25*sizeof(TCHAR));
szCurrent = NULL; LPTSTR szPath =
(LPTSTR)malloc(25*sizeof(TCHAR)); BOOL
check =
BrowseForFolder(hwnd,szCurrent,szPath);
if( check == TRUE) {
dlg.SetDlgItemTextW(IDC_EDIT1,szPath);
}

}

BOOL BrowseForFolder(HWND hwnd,
LPCTSTR szCurrent, LPTSTR szPath) {
BROWSEINFO bi = { 0 }; LPITEMIDLIST
pidl; TCHAR szDisplay[256]; BOOL
retval;

//CoInitialize();

bi.hwndOwner = hwnd;
bi.pszDisplayName = szDisplay;
bi.lpszTitle = TEXT("Please
choose a folder."); bi.ulFlags
= BIF_RETURNONLYFSDIRS | BIF_NEWDIALOGSTYLE; bi.lpfn
= BrowseCallbackProc; bi.lParam = (LPARAM) szCurrent;

pidl = SHBrowseForFolder(&bi);

if (NULL != pidl) {
retval = SHGetPathFromIDList(pidl, szPath);
CoTaskMemFree(pidl); } else {
retval = FALSE; }

if (!retval) {
szPath[0] = TEXT('\\0'); }

CoUninitialize(); return retval;

} static int CALLBACK
BrowseCallbackProc(HWND hwnd,UINT
uMsg, LPARAM lParam, LPARAM lpData)
{
// If the BFFM_INITIALIZED message is
received // set the path to the start
path.
switch (uMsg) { case
BFFM_INITIALIZED: { if (NULL !=
lpData) { SendMessage(hwnd,
BFFM_SETSELECTION, TRUE, lpData); }
} }

return 0; // The function

25个字符似乎对于完整的路径长度来说有点短，我将使用MAX_PATH。
