C# WPF: Open a CHM Help File to a specific page

Question

_{Friday, May 6, 2016 7:02 PM}

On my WPF dialog/form I have a help icon that recognizes a Mouse Down event and allows the user to view help files in a CHM format.

I cannot get it to go directly to the desired page, instead it opens to the default.

I have tried the following:

Example1 (this works as expected):

System.Windows.Forms.Help.ShowHelp(null, @"..\CN.Help\CN_Help_EN.chm");

Example 2 (does not behave any different than example 1)

System.Windows.Forms.Help.ShowHelp(null, @"..\CN.Help\CN_Help_EN.chm", "HorizontalBatch.htm");

Example 3 (reference by keyword? Same as example 1&2)

System.Windows.Forms.Help.ShowHelp(null, @"..\CN.Help\CN_Help_EN.chm", "Horizontal Batch Mix Report");

Any suggestions as to where to go from here?

GOT IT!!!

It needed a qualified path "html\

System.Windows.Forms.Help.ShowHelp(null, @"..\CN.Help\CN_Help_EN.chm", **@"html\**HorizontalBatch.htm");
