Then you just assingn the value ContextID to the ContextID property of the control. see below <BR /> <BR /> The HelpContextID property associates a specific topic in a custom Microsoft Windows Help file with a specific control.<BR /> <BR /> Syntax<BR /> <BR /> object.HelpContextID [= Long]<BR /> The HelpContextID property syntax has these parts:<BR /> Part Description <BR /> object Required. A valid object. <BR /> Long Optional. A positive integer specifies the context ID of a topic in the Help file associated with the object. Zero indicates no Help topic is associated with the object (default). Must be a valid context ID in the specified Help file. <BR /> The topic identified by the HelpContextID property is available to users when a form is running. To display the topic, the user must either select the control or set focus to the control, and then press F1.<BR /> The HelpContextID property refers to a topic in a custom Help file you have created to describe your form or application. In Visual Basic, the custom Help file is a property of the project.<BR /> <BR /> Fred Castillo Sat, 04 Feb 2006 14:11:26 GMT https://forums.autodesk.com/t5/vba-forum/implimenting-whats-this-help/m-p/1548660#M37094 fxcastil 2006-02-04T14:11:26Z
