Invoking the Windows HTML Help Engine 1

[TOMCAT]

I'm using Fujitsu COBOL Version 6.1 and cannot figure out how to call the Windows HTML engine. A Windows API or the Common Dialog Control from Microsoft works fine for the standard Windows help engine but the API for HTML requires use of an .OCX file and not a library. Has anyone crossed this bridge before?

Hello Tomcat

Please, go to

http://www.allapi.net

in the Vb Samples section.
You will find the DHTML.OCX supplied from Microsoft and download it.

Hope in this help.

Gianni,

Thanks for the information. The Fujitsu support team offered their solution as follows:

CALL "HtmlHelpA" WITH STDCALL LINKAGE USING
BY VALUE WS-HANDLE
BY REFERENCE WS-HELP-FILE-NAME
BY VALUE 0 0
END-CALL.

You will need to link in two libraries for this to work:
ADVAPI32.LIB
HTMLHELP.LIB

WS-HANDLE = 0
WS-HELP-FILE-NAME = FILE.CHM

Hello Tomcat

Thanks for your advice.

I didn't know if you are using API calls, because i suggest you to download the API Guide from

http://www.allapi.net.

It is a good solution to discovered some API functions that can be used with Powercobol more easily. An if you know somethings about Visual Basic there are a lot of sample code that can help you to understand much better how to use them with Powercobol, of course, "translating" the code.)

Also i inform you that not all libraries are available with Powercobol and you need to have the Visual Studio to complete some connections to api.

Let me know if this hint help you.
