求打开文件对话框的Window api

不用 MFC的

The GetOpenFileName function creates an Open common dialog box that lets the user specify the drive, directory, and the name of a file or set of files to open.

BOOL GetOpenFileName(
LPOPENFILENAME lpofn // address of structure with initialization data
);


Parameters

lpofn

Pointer to an OPENFILENAME structure that contains information used to initialize the dialog box. When GetOpenFileName returns, this structure contains information about the user's file selection.



Return Values

If the user specifies a filename and clicks the OK button, the return value is nonzero. The buffer pointed to by the lpstrFile member of the OPENFILENAME structure contains the full path and filename specified by the user.
If the user cancels or closes the Open dialog box or an error occurs, the return value is zero. To get extended error information, call the CommDlgExtendedError function, which can return one of the following values:

CDERR_FINDRESFAILURE CDERR_NOHINSTANCE
CDERR_INITIALIZATION CDERR_NOHOOK
CDERR_LOCKRESFAILURE CDERR_NOTEMPLATE
CDERR_LOADRESFAILURE CDERR_STRUCTSIZE
CDERR_LOADSTRFAILURE FNERR_BUFFERTOOSMALL
CDERR_MEMALLOCFAILURE FNERR_INVALIDFILENAME
CDERR_MEMLOCKFAILURE FNERR_SUBCLASSFAILURE
