Unintentionally closing an IDE component could result to total disarray. To show one of its important components, the Control toolbox, use any of the following methods:
Method 1:
1. Right-click an empty pane in the Microsoft Visual C++ toolbar. A pop-up menu containing several options will be displayed>Select Controls option.
Note: The Controls option only appears on the pop-up menu if your dialog-based application is shown on the screen. If you dialog-box is hidden, click the resource tab on the right pane of you Visual C++ IDE> Expand the Dialog tree control item>Double-click IDD_Nameofyouproject_DIALOG.
Or
Method 2:
1. Click on the tools menu>Customize>Click the toolbars tab.
