Dan,
Sounds like a worthwhile project. I belive someone did something like this before, but its still worth refining. I have some web space I can donate (I don't know C so I can't help there). However, I would have one problem. Since @Yahoo.com and @Hotmail.com are the source of 84% of the spam coming into my email servers, I block both domains. So unless you have another account you can use, we won't be able to converse via email

Well, here's the latest.

hConv version 0.10 seems to be processing Type...End Type
structures now. Also, numeric constants seem to be working
correctly.

I've been using the sample including with Kev Peel's HDR2INC
and can say that my program has basically all his functionality,
sans the comment removal mentioned above.

The differences are in how data types are handled. For example,
according to the PB docs, char translates as byte, but Kev's
program converts it to an asciiz.

This is where I need help.

How can give I give my logic the "knowledge" of which to use.

Also, for the moment, I've stuck with the basic types in the
PB docs. Again, to add more, this is where I'll need help.

I've ordered some web space that will be up in the next couple
of days with a dedicated email address for this project. I'll
post that here when that is up.

I'll likely post the source with it, although I wrote this
quickly and I'm sure my programming style won't meet with
everyones approval. It's just a program that kinda came together
without much preplanning. Y'all know how that goes... It surely
won't be a clean "compiler" like The PowerBasic Team would
have written.

Here's how I plan to proceed.

I would still like to get some 'c' headers that have been
sucessfully converted to PB. I can run those 'c' headers
and compare the results and tweak the program until I get
positive results.

After I have a couple converting well, then I'll post the EXE
so that y'all can try it out on your own and provide me
feedback on the quality of conversion.

Next, I'll tackle something more complicated, like the ISource
headers. Those who wish to help, when I come into a stumbling
block, I'll send everyone an email with the relevant lines
(only those as referred pertaining to a particular conversion)
and hope to receive back examples of how to convert it.

Well, I guess that's about it. I think I'm going to hold off
on any further development until I start to hear from people,
either via email (temporarily at) [email protected] or
in this post.

Thanks a bunch!

Dan

Count me in Dan. This is a very interesting project.

Well, I've been working hard and am now out of Oreo's,
which isn't such a bad thing, I suppose.

Anyhow, I've been working with the converter and have made
lots of progress swatting some nastly little bugs and little
pecularities. Hey, it's version 0.11 right now.

I've purchased some web space and have developed a web site
documenting what this program does, step-by-step, and has a
section for posting code that I don't know how to handle for
y'all to email me your input. I'll post the URL when the DNS
servers update in a couple of days.

I'll also post the source and PB/Win 7 compiled EXE there as
soon as I pretty up the user-interface just a tad, probably
by the end of the week.

Well, I've used the example.h included with Kev Peel's HDR2INC
and added a #define and a couple of typedef's that I assume
have to be substituted.

Here's the example.h file that I used for my initial tests:

Code:

#define CONSTANT1         0
#define CONSTANT2         1
#define CONSTANT3         2
#define CONSTANT4         3
#define CONSTANT5         4

typedef LPCSTR ARRAYTYPE;

#define _IS3EXP_ extern

typedef UINT32 HISSRC;
typedef IS3CALL __stdcall;

typedef void Mysubroutine (
     const char *Param1,
     Int Param2);

typedef uint Test (
     byte *value);

typedef Int MyFunction (
     Long Param1,
     Dword Param2,
     Long *Pointer1,
     Long *Pointer2);

#define MYCONST1                1
#define MYCONST2                2
#define MYCONST3                3
#define MYCONST4                4
#define MYCONST5                5
#define MYSTRINGLEN_A        10
#define MYSTRINGLEN_B        50

_IS3EXP_ HISSRC IS3CALL IS3FunctionName(const char * pFileName);

typedef struct st_MyStruct {
 char stringmember1[32];
 char stringmember2[MYSTRINGLEN_A];
 Dword numarray1[32];
 Dword numarray2[MYSTRINGLEN_B];
 LPCSTR stringptrarray[32];
 ARRAYTYPE anotherstringptrarray[32];
 const char MYCONST1mychars[4500];
} MyStruct;

And (drum-roll, please) here's the code hConv created:

Code:

     %CONSTANT1 = 0 
     %CONSTANT2 = 1
     %CONSTANT3 = 2
     %CONSTANT4 = 3
     %CONSTANT5 = 4
'
     Declare Sub Mysubroutine Alias "Mysubroutine" ( _
          Param1 As BYTE Ptr, _
          ByVal Param2 As LONG)
'
     Declare Function Test Alias "Test" ( _
          value As BYTE Ptr)
               As DWORD
'
     Declare Function MyFunction Alias "MyFunction" ( _
          ByVal Param1 As LONG, _
          ByVal Param2 As DWORD, _
          Pointer1 As LONG Ptr, _
          Pointer2 As LONG Ptr)
               As LONG
'
     %MYCONST1 = 1
     %MYCONST2 = 2
     %MYCONST3 = 3
     %MYCONST4 = 4
     %MYCONST5 = 5
     %MYSTRINGLEN_A = 10
     %MYSTRINGLEN_B = 50
'
     Declare Function IS3FunctionName Lib "nameof.dll" Alias "IS3FunctionName" ( _
          pFileName As BYTE Ptr)
               As DWORD
'
     Type st_MyStruct
          stringmember1 as ASCIIZ * 32
          stringmember2 as ASCIIZ * %MYSTRINGLEN_A
          numarray1(32) as DWORD
          numarray2(%MYSTRINGLEN_B) as DWORD
          stringptrarray(32) as ASCIIZ PTR
          anotherstringptrarray(32) as ASCIIZ PTR
          MYCONST1mychars as ASCIIZ * 4500
     End Type

Please take a look at it. If I've got something wrong in this
simple example, please, by all means, let me know either here
at [email protected] (removing the cap letters).

(Not demonstrated here is that hConv merges in
#include "filename.h" files, too, thus creating one large INC
file out of multiple files.)

Remember, if you've got experience in converting c headers to
PowerBasic, I really need your help so that I can attempt to
make this as complete of a conversion as possible. (Yes, I'm
sure there'll be some situations it won't be able to handle.
I just want to cover as much ground as possible.)

Again, I'll post right here, same channel, the web site
URL when it's up.

See 'ya
