how to run the .chm file from the helptopic menu?

[Eric4ever]

the title says all.

i found that some methods are like this:
  .data
calculator db "C:\WINDOWS\system32\calc.exe",0

the definetion must have absolute path, and i want to run the .chm file(the same directory as the application file) from the help topic menu, how can i do it?

thanks in advance.

http://en.wikibooks.org/wiki/Windows_Programming/Compiled_HTML_Help seems to explain how to open html help files.

Thanks Stan :U

[Eric4ever]

there is still a question.

how to convert the htmlhelp.h to htmlhelp.inc?
i tried the 'h2inc' application, but it errors at line 170...

[stanhebben]

I see there's a htmlhelp.inc file in the masm include files, but that one seems a bit limited.

Sec, I'll translate it manually. (only 400 lines  :wink)

Ok, here it is. Enjoy!

And correct my errors, if any.

thanks Greg, it's ok, but there is still a question: how can i link to the help file in the current directory?

I define the help file liake this:

szHelpFile    db    "D:\Project\program\help.chm",0


the help menu can only be valid when the help file exists at the D:\Project\program directory. when I move the folder which contains the application and help file, the help menu is invalid. so, how can i make it move-and-run? i try to define is as:
szHelpFile    db    ".\help.chm",0

but it error..

[stanhebben]

Must be ..\help.chm I think.

thanks Greg, it's ok, but there is still a question: how can i link to the help file in the current directory?

If the help file should always be in the same folder as the running app, use:

Code Select Expand

invoke GetCurrentDirectory, (returnbufferlength), (returnbufferpointer)
Then you'll have to concatenate your "\help.chm" onto the end of whatever's returned. Make sure you check whether there's already a "\" on the end of that, I'm not sure whether the path returning API routines add it.

Would using GetModuleFileName be a better idea? I always use that to evaluate the .ini location of my app.

[Mark Jones]

Shantanu is correct, GetCurrentDirectory does not necessarily return the directory the calling app is running from, whereas GetModuleFileName does. I found that out the hard way. :wink

[Eric4ever]

local    @szBuffer[128]:byte

invoke    GetModuleFileName,NULL,addr @szFileName,MAX_PATH
......


the GetModuleFileName retrieves the full path and filename, what should I do the in the next step in order to prepare for the invoke of htmlhelp?

thanks in advance.

Include SHLWAPI include and library and use PathRemoveFileSpec(szPath) and PathCombine(szBuffer, szPath, szFile).
