How to stop overwriteprompt when creating SaveFileDialog using GetSaveFileName

Thanks

SaveFileDialog dialog = new SaveFileDialog();

I'll update this if I've misunderstood what you're asking (and I'm sorry if I have if you provide your current code. But, you can do:

yourSaveFileDialog.OverwritePrompt = false;

Actually I could finally find the solution for my question and I would like to place it here as I think it may be useful to someone...

When creating the SaveFileDialog using GetSaveFileName Windows function, we have to send a reference to an OPENFILENAME struct (consider it as ofn) which contains details required to create the savefiledialog. In this struct, we have to set flags for what we need, thus if we want to stop the overwrite prompt, we should not set a flag for it:

The flag setting should be ofn.Flags = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_NOTESTFILECREATE | OFN_ENABLEHOOK | OFN_HIDEREADONLY;

From the .NET SDK:

SaveFileDialog Class

...

Properties

...

OverwritePrompt - Gets or sets a value indicating whether the Save As dialog box displays a warning if the user specifies a file name that already exists.

You can set the property of your dialog to false to disable overwrite prompts.

You can set OverwritePrompt property to false like so:

 SaveFileDialog dialog = new SaveFileDialog();
 dialog.OverwritePrompt = false;
 dialog.ShowDialog();
