Subject: Re: [wxlua-users] Writing equations 
 
Hi John,
     For the equation I am interested in rendering the equation on screen not on evaluating it. Somewhat like a browser renders MathML or these math packages like Mathematica, Maxima or just the equation writer of Microsoft Word. Do you have any pointers for that?

Thanks,
Milind

Hi,

I have used this library before and it works as advertised :
http://warp.povusers.org/FunctionParser/

However, a pure Lua solution is probably what you want and I have not attempted to do that either. I would think that if you get a string from a user then run it through some checks to make sure it doesn't have 'if', 'for', 'os.execute', or any other nastyness, prepend "return" to it then use pcall() to run it that should work. The hard part is getting all the check rights so you don't have any security holes and the user can't crash/lock-up your program.

ps. I'll check the controls later tonight when I can get to a MS Win machine and respond in your other thread.

Just to clarify: I tried both ways and got it to work. I tried
compiling from scratch with zbstudio.exe and I also tried moving
manifest from wxlua to lua.exe as I described earlier.

For compiling from scratch I used this script:
https://github.com/pkulchenko/ZeroBraneStudio/blob/master/build/build-win32.sh#L247-L248
and the files are here:
https://github.com/pkulchenko/ZeroBraneStudio/tree/master/zbstudio/res
(zbstudio.rc and zbstudio.manifest; this manifest doesn't reference
Common-Controls as I couldn't get it to work with my mingw-compiled
2.9.5, but it works with your 2.8.12 dlls).

Paul.

Hi John,

I went the easy way: I extracted the manifest from wxlua and added it
to lua.exe:

"C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\mt.exe"
-inputresource:wxlua.exe -out:extracted.manifest
"C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\mt.exe" -manifest
extracted.manifest -outputresource:lua.exe

After that wxlua and lua produce the same (calendar) results. You can
also tweak the manifest before embedding it to see the effect.

Not sure; when I tried the same manifest with my wx.dll compiled with
mingw, I get side-by-side error:

Activation context generation failed for "...zbstudio.exe". Dependent
Assembly Microsoft.Windows.Common-Controls,publicKeyToken="6595b64144ccf1df",type="win32",version="6.0.0.0"
could not be found.

When I copy all the dlls from 2.8.12 and run with the same executable,
everything is fine. I'm not sure what dll I'm missing, but I thought
it was one of wxmsw28_*vc_custom.dll.

Paul.

I just added a resource and manifest file for wxLua's lua.exe, but it
didn't change how the calendar control looked.

Is there anything that you did differently?

I don't know what you mean. What DLL is included with Windows that you ship?
