Hello ,
I'm using robohelp the last version to make a file .chm which there i can include my online manual.I design it in the robo and when i compile it the robo makes an chm file.So far enerything is ok.But the problem starts with powerbuilder 7.03.PB has ready function to call hlp files but it doesn't have function to call chm files.I have tried to declare an local external function to call an api.I wrote the following code in the declaration area
"Function long HtmlHelp(long hwndCaller,string pszFile, long uCommand , any dwData ) Library "HHCtrl.ocx" "
HHCtrl.ocx is an active x control which can call htmlhelp function where you can pass arguments.I wrote down the following code
"ll = HtmlHelp(0, "c:\zakshare\testhelp\resources.chm", HH_DISPLAY_TOPIC , "c:\zakshare\testhelp\poroi.htm" )" but the main problem exists.I cannot open the chm file.Can you help me ???Thank you

Well! There should be an app that launches the .chm files that accepts a .chm file as an argument and opens it (eg: c:\windows\Notepad.exe c:\Documents\demo.txt). You could give the name of the executable that launches the .chm file and give the .chm file-name as a command-line parameter.

If your users have the .chm launcher in different locations on their computers, you may copy this executable to a central place such as a network file-server and hard-code the pathname of the executable into the Run() function with the parameter of the .chm file.

Regards,

The name of the executable is HH.exe (HTML Help Executable). On my machine, it is in the Windows folder and it works fine when executed with a parameter.

Good luck!
