draw the button icon by selecting the white button in the toolbar drawing is done using the tools provided by the programming environment.Ģ. Deleting a button is done by dragging the respective button from this list (click on the button, hold the left mouse button pressed and pull the button outside the toolbar and then release the button).ġ. We expand Tool Resources to see the application resourcesĤ. To delete a button from the toolbar, you must do the following:Ģ. This functionality is provided by AppWizard and MFC. AppWizard provides a docking toolbar (the toolbar is not fixed, can be moved anywhere in the client area, looks like a floating palette) by default for this application. Next we will exemplify based on an application, called Tool, with a Document/View and MDI architecture. Based on this ID we will attach a button command. It is our responsibility to modify the toolbar as we wish.Įach button on the toolbar has an ID that identifies it. The toolbar can be added with the AppWizard.ĪppWizard creates the toolbar for the most used commands in File, Edit and Help.

In general, the toolbar buttons are duplicated for menu commands (shortcuts). Use the COleBusyDialog class to display this dialog box.The buttons on the toolbar correspond to commands, just like the items in a menu. These dialog boxes are displayed via COleMessageFilter, based on an implementation of the OLE interface IMessageFilter, and the user can decide whether to attempt the activation request again. The Server Not Responding dialog box is displayed if the server doesn't respond to the activation request at all. The Server Busy dialog box is displayed when the user attempts to activate an item and the server is currently unable to handle the request, usually because the server is in use by another user or task. Use either the COleLinksDialog or the COleUpdateDialog class, depending on which dialog box you want to display.

Usually, the Update Links dialog box is displayed when a compound document is first opened. Display the Edit Links dialog box when the user chooses Links from the Edit menu. The Update Links dialog box verifies the sources of all the linked items in the current dialog box and displays the Edit Links dialog box if necessary.

The Edit Links dialog box allows the user to change information about the source of a linked object. For an example, run the MFC OLE sample OCLIENT. Use the COleConvertDialog class to display this dialog box. This dialog box is often displayed by clicking item type Object on the Edit menu and then, on the cascading menu, clicking Convert. For example, if you've embedded a metafile in a compound document and later want to use another application to modify the embedded metafile, you can use the Convert dialog box. This dialog box allows the user to change the type of an embedded or linked item. Use the COleChangeIconDialog class to display this dialog box. Also display it when the user opens the Insert Object dialog box and chooses Display as Icon. Display this dialog box when the user chooses Change Icon from the Edit menu or chooses the Change Icon button in either the Paste Special or Convert dialog boxes. This dialog box allows the user to select which icon is displayed to represent the linked or embedded item. Use the COlePasteSpecialDialog class to display this dialog box. Display this dialog box when the user chooses Paste Special from the Edit menu. The user can choose the format of the data, whether to embed or link the data, and whether to display it as an icon. This dialog box allows the user to control the format used when pasting data into a compound document. An application that's a container/server can't be inserted into itself unless it's an SDI application.

You can't insert an MDI application into itself. Use the COleInsertDialog class to display this dialog box. Display this dialog box when the user chooses Insert Object from the Edit menu. It also allows the user to choose to display the item as an icon and enables the Change Icon command button. This dialog box allows the user to insert newly created or existing objects into the compound document. For details on OLE dialog boxes and the structures used to customize their behavior, see MFC Reference. This article lists the tasks handled by the OLE dialog boxes and the classes needed to display those dialog boxes. The MFC OLE classes provide default dialog boxes to gather the required information. While a user runs an OLE-enabled application, there are times when the application needs information from the user to carry out the operation.
