Ensures that the dlgitem is visible when window is open. This function is specifically useful on the toolbar, since it automatically invokes a re-display of the toolbar, shifting the other toolbar buttons to the right (if necessary) to create space for the button displayed (if the window is already open, you will see a momentary flash as this re-display takes place).

The window parameter is a window identifier. dlgitem is the value of the control's id attribute.

Example
