Hi

I think I need more help.


It has been suggested that I use dvipng.exe,
part of the LaTeX (MikTeX) distribution rather than
GladTeX. This seems like a good idea.

The problem I have actually applies to both methods.

I can create a .png file from the Command prompt; for example the command
     "c:\Program Files\MikTeX 2.5\miktex\bin\dvipng" c:\gladtex\myeq000'
works.

But how do I replicate this 'DOS' command from within BlackBox?

My attempt is below - maybe WinApi.WinExec is the wrong call?


The result I get is 33, which I don't think is an error code.
If I deliberately get the path wrong the result I get is 3, which I do think
is an error code.


Cheers

Robert


PS - I have had 3 people contribute to this thread privately, as their attempts
to use the list have not worked. In future, if you ask, I will try to forward
such messages to the list myself.


MODULE RdcLatex;
IMPORT Fmtrs := LibFmtrs, Api := WinApi, SYSTEM;

VAR
   f : Fmtrs.Fmtr;
   str : ARRAY 80 OF CHAR;

(* PROCEDURE WinExec (lpCmdLine: WinApi.PtrSTR; uCmdShow: INTEGER): INTEGER; *)
PROCEDURE Do*;
   CONST
     cmdStr = '"c:\Program Files\MikTeX 2.5\miktex\bin\dvipng"
c:\gladtex\myeq000';
   VAR
     res : INTEGER;
     cmd : ARRAY [untagged] 80 OF SHORTCHAR;
   BEGIN
     cmd := cmdStr;
     res := Api.WinExec (cmd, 0);

     f.SetToEnd;
     f.StrIntLn ('Result = ', res, 0)
   END Do;


BEGIN
   f := Fmtrs.logFmtr
END RdcLatex.
