Intercept Help (F1) key to replace MS Help system Intercept Help (F1) key to replace MS Help system RoyLofquist (Programmer) (OP) 21 Oct 99 09:36 How can I intercept the MS help call (F1 key) so that I can use my own help system? RE: Intercept Help (F1) key to replace MS Help system Katriona (Programmer) 1 Nov 99 06:14 Search MSDN on the HelpContextID property. You assign numbers to the HelpContextID property for all the controls you want to respond to the F1 key. You assign the Topic ID/Help ID for each control as determined in the windows help you have developed. You have to set the HelpFile property of your application to the name of your help file. Search MSDN on the HelpFile Property. Hope this helps.
