Paradox 9.0 and XML

Hello!

I would like to send XML to certain IP address and wait for XML.
Is this possible from ObjectPal? And how?

Thanks in advance

Hi Marjeta,

I think the easiest way to get this task done is to do this with an ActiveX control or a DLL. I would write it in Delphi 7 Enterprise, but other solutions exist. D7 Enterprise has just about the best Win32 XML support.

Good luck,

Thanks for your advice - I'll probably follow your advice in programming a DLL.

Currently my friend made a java class ( which creates XML, sends it to IP address and waits for responded XML ), which is started in batch file, initiated by "execute" command in my ObjectPAL method.

It seems to me a very awkward solution, but I'm not acquainted with ActiveX control. Where should I start ?

Thanks a lot
Marjeta

I still have problems in sending and receiving XML.
Following your advice, Mike, a friend of mine made a DLL in Delphi , containing a function with parameters:

RToMR(AURL,ACert,AReq,AResp:PChar;ARespLen:DWORD):DWORD;

In my script the function is declared in uses block:
Uses rd2mr

RToMR(AURL CPTR, ACert CPTR, AReq CPTR, var AResp CPTR,var ARespLen CLONG ) CLONG

endUses

In script the function is called:

retc = RedarstvoToMRVL(AURL,ACert,AReq,AResp,ARespLen)

where variables are declared as foolows:
var
AURL String
ACert String
AReq String
AResp String
ARespLen LongInt
retc LongInt
endvar

AURL, ACert and Areq are filled with values, AResp is filled with number of blanks and ARespLen is the length of AResp.

Still the error occurs:
"Access violation at address 03513577 in module 'red2mrvl.dll'. Read of address 00000064" - this is the area of AResp, which I filled with 100 asterisks.

I suppose there's an error in passing parameters - I intended to pass first three parameters by value and the last two by pointer - where did I make a mistake ?

Thanks in advance
