   cautoex -d

MORE INFORMATION

Cautoex.exe contains the following two sample applications:

  • Cauto is a local OLE Automation component sample application written in C. It contains a dialog box that prompts for text and a position to display that text on the main window. It exports, using OLE Automation, the text property as well as methods to get and set the position of the text and to refresh the main window of the component. A dual interface is used to support all of the automation. This dual interface is described in the object definition language file CAUTO\cauto.odl. IDispatch::GetIdsOfNames and IDispatch::Invoke simply call DispGetIDsOfNames and DispInvoke respectively.
  • Cautocon is a simple OLE Automation controller written in C that controls the Cauto application. There is a dialog that prompts for text and position. Cautocon then uses OLE Automation to draw that text at the appropriate position on the component's main window. This dialog box is activated by clicking Set on the Text menu. It is loaded with the text and position from the component's main window each time it is activated.
