Examples
The following code example illustrates creating a SaveFileDialog, setting members, calling the dialog box using the ShowDialog method, and saving the current file. The example requires a form with a button placed on it.
private:
void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
Stream^ myStream;
SaveFileDialog^ saveFileDialog1 = gcnew SaveFileDialog;
saveFileDialog1->Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
saveFileDialog1->FilterIndex = 2;
saveFileDialog1->RestoreDirectory = true;
if ( saveFileDialog1->ShowDialog() == ::DialogResult::OK )
{
if ( (myStream = saveFileDialog1->OpenFile()) != nullptr )
{
// Code to write the stream goes here.
myStream->Close();
}
}
}
private void button1_Click(object sender, System.EventArgs e)
{
Stream myStream ;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
saveFileDialog1.FilterIndex = 2 ;
saveFileDialog1.RestoreDirectory = true ;
if(saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if((myStream = saveFileDialog1.OpenFile()) != null)
{
// Code to write the stream goes here.
myStream.Close();
}
}
}
Private Sub button1_Click(sender As Object, e As System.EventArgs)
Dim myStream As Stream
Dim saveFileDialog1 As New SaveFileDialog()
saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"
saveFileDialog1.FilterIndex = 2
saveFileDialog1.RestoreDirectory = True
If saveFileDialog1.ShowDialog() = DialogResult.OK Then
myStream = saveFileDialog1.OpenFile()
If (myStream IsNot Nothing) Then
' Code to write the stream goes here.
myStream.Close()
End If
End If
End Sub
Remarks
This class can either open and overwrite an existing file or create a new file.
Most of the functionality for this class is found in the FileDialog class.
Constructors
| SaveFileDialog() |
Initializes a new instance of this class. |
Properties
| AddExtension |
Gets or sets a value indicating whether the dialog box automatically adds an extension to a file name if the user omits the extension. (Inherited from FileDialog) |
| AddToRecent |
Gets or sets a value indicating whether the dialog box adds the file being opened or saved to the recent list. (Inherited from FileDialog) |
| AutoUpgradeEnabled |
Gets or sets a value indicating whether this FileDialog instance should automatically upgrade appearance and behavior when running on Windows Vista. (Inherited from FileDialog) |
| CanRaiseEvents |
Gets a value indicating whether the component can raise an event. (Inherited from Component) |

Gets or sets a value indicating whether the dialog box displays a warning if the user specifies a path that does not exist. (Inherited from FileDialog) |
| CheckWriteAccess |
Gets or sets a value indicating whether the dialog box verifies if the creation of the specified file will be successful. If this flag is not set, the calling application must handle errors, such as denial of access, that are discovered when the item is created. |
| ClientGuid |
Gets or sets the GUID to associate with this dialog state. Typically, state such as the last visited folder and the position and size of the dialog is persisted based on the name of the executable file. By specifying a GUID, an application can have different persisted states for different versions of the dialog within the same application (for example, an import dialog and an open dialog). This functionality is not available if an application is not using visual styles or if AutoUpgradeEnabled is set to |
