This function creates a system-defined dialog box that enables the user to select a file to open.
BOOL GetOpenFileName( LPOPENFILENAME lpofn );
[in] Long pointer to an OPENFILENAMEstructure that contains information used to initialize the dialog box. When GetOpenFileNamereturns, this structure contains information about the user's file selection.
Nonzero indicates that the user specified a file name and clicked the OKbutton. The buffer pointed to by the lpstrFilemember of the OPENFILENAMEstructure contains the full path and filename specified by the user.
Zero indicates that the user canceled or closed the Opendialog box or that an error occurred. To get extended error information, call GetLastError. GetOpenFileNamesets only the ERROR_INVALID_PARAMETER and ERROR_OUTOFMEMORY errors.
Not all members of the OPENFILENAMEstructure are defined in Windows Embedded CE. For information about the defined members, see the reference topic for the OPENFILENAMEstructure.
Windows Embedded CE modifies the meaning of the following members of the OPENFILENAMEstructure when it is passed into the GetOpenFileNamefunction.
If this member is set to the OFN_PROJECT value, the GetOpenFileNamefunction opens the Folderdialog box. Otherwise, the function opens the Opendialog box.
When GetOpenFileNamereturns successfully, this member is used to retrieve full path of the selected file name.
When GetOpenFileNamereturns successfully, this member is used to retrieve the project folder name only.
Pointer to a string that receives the initial folder name, but not the full path name.
When the GetOpenFileNamefunction is called, Windows Embedded CE adds the following prespecified undefined members:
|Windows Embedded CE||Windows CE 1.0 and later|
|Windows Mobile||Windows Mobile Version 5.0 and later|
