I'm just getting into Delphi 2009 from D6. I have help in my apps but that doesn't work. My current code is

TVar := True;
HH := Exe_Dir(TVar) + '\VBSHelp\VBSHelp.hlp';
Application.HelpFile := HH;
Application.HelpCommand(HELP_FINDER, 0);

This doesn't work in 2009. I have looked for what needs to be done but can't find anything. I need your "help", no pun intended. Thanks.

No one has a Help file in your D2009 app? If you do, how do you display it?

George

Personally I've never included a context sensitive help in my apps.

I got an answer from the Embarbadero Forum. If you add WinHelpViewer to the Uses clause it will work, i.e., you can display an hlp Help file. Something to maybr remember

I have also been told that Microsoft, in their infinite wisdom, removed WinHelp support in Vista and probably in Windows 7. I still aim at XP but I guess I will have to change my approach. It was suggested I look at HelpScribble.

George

Yeah, in Vista you have to download and install WinHelp to be able to open the help files.

I use Shalom Help Maker for hlp files. It is free.

I also use Shalom but I have talked with them and they are not going to make .chm files sooooo I may have to get the .hlp file and convert it since Vista and Windows 7 are problems. I still don't know how to display a .chm file in D2009. Any suggestions?

George

I never attempted to make a chm file context sensitive for an application. I may do this for my next Delphi project. Here is a page that explains how to use a chm file for context sensitive help. http://www.roboauthor.com/online_docume ... 00000a.htm Another option is to launch the chm file from an event such as a button-click.

Hi geo

For context help I suggest using a side or bottom panel containing a rich text control (memo) with maybe a nice pale yellow color and read-only.
Then you simply load up some rich text from a subfolder of your app. Much better than wasting time making help files.

However, a chm download can be useful for a potential client who may like to assess your software before downloading/installing.

I decided to try ShellExecute and that worked. I put a Menu item Help which did the following...

ShellExecute(Handle, 'open', PChar(DD), nil, nil, SW_SHOWNORMAL);

where DD is the string c:\YourApp\TheHelpFile.chm

You need ShellAPI in the Uses clause.
