This class cannot be inherited. The following code example creates an OpenFileDialog , sets several properties to define the file extension filter and dialog behavior, and displays the dialog box using the CommonDialog.
ShowDialog method. The example requires a form with a Button placed on it and a reference to the System. IO namespace added to it. This class allows you to check whether a file exists and to open it. The ShowReadOnly property determines whether a read-only check box appears in the dialog box.
The ReadOnlyChecked property indicates whether the read-only check box is checked. Most of the core functionality for this class is found in the FileDialog class.
Yes localizes the dialog's File Name , Open , and Cancel buttons. If the property is not set to RightToLeft. Yes , English text is used instead. If you want to give the user the ability to select a folder instead of a file, use FolderBrowserDialog instead. Initializes an instance of the OpenFileDialog class. Gets or sets a value indicating whether the dialog box automatically adds an extension to a file name if the user omits the extension. Gets or sets a value indicating whether this FileDialog instance should automatically upgrade appearance and behavior when running on Windows Vista.
Gets or sets a value indicating whether the dialog box displays a warning if the user specifies a file name that does not exist.
Gets or sets a value indicating whether the dialog box displays a warning if the user specifies a path that does not exist. 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 false.
Gets the IContainer that contains the Component. Gets the custom places collection for this FileDialog instance. Gets or sets a value indicating whether the dialog box returns the location of the file referenced by the shortcut or whether it returns the location of the shortcut. Gets a value that indicates whether the Component is currently in design mode.
Gets the list of event handlers that are attached to this Component. Gets or sets the current file name filter string, which determines the choices that appear in the "Save as file type" or "Files of type" box in the dialog box.
Gets values to initialize the FileDialog. Gets or sets a value indicating whether the dialog box restores the directory to the previously selected directory before closing. If you want the path of a server file or folder, you have to get the server to give a list of possible folders to choose from.
The easiest solution is to tell the user to browse in Explorer and copy the path, to paste in your dialog. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

If you need to test whether the file name is being taken or not then you may take a textbox and change text property of textbox at runtime.
So in console application, I do get the file name. So the FileOpenDialog does work. But it just doesn't seem to "cleanup" once it is closed. About application choice, this indeed a console application written by another group which I don't have control over.
I just have a hook in this application to control some functionality. So I cannot really change it to windows app. As a part of my hook, I need to accept some complex inputs from user, including getting data from database. So I have actually put together a windows forms application, set the output type to library and am using the library in console application. It all works fine, except for this FileOpenDialog.
So I am not sure what is it that FileOpenDialog is doing that causes this. Yes, that is all the code there is. I created another new Console application and still saw the issue. I created a new Console Application, added reference to System. Forms and added the using statement as shown below:.
Are you using VS ? Im currently using VS under W8 rtm, i added a new console app with your code, and running the code ended normally after invoking the open dialog and the console.
Anyway, maybe there is some garbage collection issue, so i suggest you to add ofd. Dispose on the end of method to ensure its being disposed. Forms gives me an error in Forms, Why? Ask a question. Quick access. Search related threads. Remove From My Forums. Answered by:. Archived Forums. Visual C.
