Add help to your winforms applications
u can find in the attach file a sample that show how to call your help file from .NET Winform (u will see in a code a call to windows API in order to do that)
The code was taken from the following resource
In the above example u will see how u can attach help information to a winfor control by using controls Tag property value which will be latter send as the help context to the windows external help API.
U can also implement the following simple logic to deal with help information:
In case the Form.ActiveControl has Tag value u sends it to help API to get the help about it. Of cource u need to create help of it within the CHM.
Otherwise – u check its parent container Tag value – and so on until u get to the Form class container which will have a Tag value for the form level help info.
Each level up in the chain will supply the user a more general help info.
