I am new to dm c++ compiler.(purchased CD 15 days back )
Till now I have used Borland C++ and borland c++builderX compiler.
Now planning to switchover to DM C++
But I get following errors.
I am compiling for WIN32 (no ODBC/no MFC )
Can some one help me ?

#include <sqltypes.h>
#include <sql.h>
#include <sqlext.h>

extern  SQLHANDLE   EnvHandle;
extern  SQLHANDLE   ConHandle;
extern  SQLHANDLE   StmtHandle;

Try turning on the macro preprocessor output with -e -l and look at the resulting .lst file.

Thank you for prompt reply...
For pinpointing I created another source file with just 5 lines of a.cpp source
code file and compiled.

it seems like sqlext.h expects windows.h to be included BEFORE it
at least it uses HWND as if it was defined, but sqltypes.h doesn't include windows.h itself for this purpose

just adding
  #include <windows.h>
before
  #include <sql.h>
solved your problem (for me)

but I use Win32 Platform SDK 2000(?) year instead of DMC's headers (which are a little old being of 96 year)

Thanks M Nic.

Added windows.h as well as removed extern word from one statement
This is cleared by BC5.5 (2000) compiler Drv-C++
I switched over to DM ( 15-20 days back ) to have latest implementations in
compiler technology. (also DM's strenth of speed,size).
Dev-C++ is toooo slow for my complex / huge packages.
SO sticking to "Win32 Platform SDK 2000" or not using latest DM will be my last
alternative.

#include <sql.h>
#include <sqlext.h>
SQLHANDLE EnvHandle;

I meant that I use DMC *with* newer PSDK header/libs
I definitely will not stop using DMC, as it seems best compiler I have ever had (and also it compiles for DOSX which is essential for good real-time apps) :)

Intel Compiler 8.1 is also good, but very slow at the same level of optimizations as DMC/ not to mention it costs $450 :)

Yes Sir, I 100% agree with you. We are in same boat.

Right now I need help for switching over to DM C++;
I dont know, where is the problem.
If problem is in sql*.h header files then it must have faced by many
programmers. So the chances of header file flaw is < 0.0001%.

Does DM need additional header files to compile this code clean?

----------a.cpp--------------
include <windows.h>
#include <sql.h>
#include <sqlext.h>
SQLHANDLE EnvHandle;
extern SQLHANDLE ConHandle;
-------------------------------

UNFORTUNATELY my guess turned out TRUE.

Borland compiler header file  sqltypes.h contains following lines. Equivalant lines are missing in DM header files.

How come no one reported this earlier? or DM uses different reserve words?

Header files of next version will have similar lines?


/* generic data structures */
#if (ODBCVER >= 0x0300)
#if defined(WIN32)
typedef void*					SQLHANDLE;
#else
typedef SQLINTEGER		SQLHANDLE;
#endif	/* defined(WIN32) */
typedef SQLHANDLE               SQLHENV;
typedef SQLHANDLE               SQLHDBC;
typedef SQLHANDLE               SQLHSTMT;
typedef SQLHANDLE               SQLHDESC;
#else
#if defined(WIN32)
typedef void*					SQLHENV;
typedef void*					SQLHDBC;
typedef void*					SQLHSTMT;
#else
typedef SQLINTEGER              SQLHENV;
typedef SQLINTEGER              SQLHDBC;
typedef SQLINTEGER              SQLHSTMT;
#endif  /* defined(WIN32) */
#endif /* ODBCVER >= 0x0300 */

Yes, I think this is the problem of MS Win32 Platform SDK
in DMC (PSDK ~96), in PSDK ~2000 and in PSDK ~2005 (downloaded last year in April) all have sql.h and sqltype.h without #include <windows.h>

This may mean that MS technicians are sure that everyone uses stdafx.h with first line "#include <windows.h>" :)

So relax, add this include and proceed porting
We can't do anything with MicroSoft :)

MS is a problem...   BUT   ......

Problem is not solved by including windows.h   nor by stdafx.h SQLHANDLE error is not solved by these header files.

defination of SQLHANDLE is missing from any .h files available with DM folder

DM has to act very quickly...  its a request from a well-wisher.
