Does anybody know how to use function of ProToolkitTaskExecute()? The following is my code segmemt. I always got the reture value: PRO_TK_E_NOT_FOUND, and I don't know why.


ProToolkitDllHandledllhandle;
ProErrorerror,err;
ProPathpropath;
ProNameproname;
ProBooleanprobool=PRO_B_TRUE;

ProStringToWstring(proname,"hellodll");
err=ProToolkitDllLoad(proname,"E:\\hello\\Release\\hello.dll ",".\\text\\usermsg.txt",probool,&dllhandle,&error,p ropath);


ProArgument*arg;//ret
ProArgument*proarg;//input

ProArgumenttmp;


ProArrayAlloc(0,sizeof(ProArgument),1,(ProArray*)proar g);
ProStringToWstring(tmp.label,"IMPGEOMTYPE");
tmp.value.type=PRO_VALUE_TYPE_INT;
tmp.value.v.i=121;

ProArrayObjectAdd((ProArray*)proarg,-1,1,& nbsp;&tmp);
error=ProToolkitTaskExecute(dllhandle,"yyg",proarg,&arg, &err);
 
I am also getting the PRO_TK_E_NOT_FOUND error. Did you guys get your programs working? I do know that the function I am trying to call must have PRO_TK_DLL_EXPORT macro in front of it's definition, which I did. But no luck, it still doesn't work.
 
Have you guys over come this PRO_TK_E_NOT_FOUND error? I am also getting same error. Please give me update on the same.

Thanks,
 
Here is my final working code to load an external dll and call a function within it.

Hi williaps,

Thanks for the prompt response.




I am copying the relevant code I am
using to make this call here -



------------------------------------------------------------ ----

ProArgument*
input_arguments = NULL;

ProArgument*
output_arguments = NULL;



status =
ProArrayAlloc( 1, sizeof(ProArgument), 1,
(ProArray*)&input_arguments);



ProStringToWstring(input_arguments[0].label,"I");

input_arguments[0].value.type=PRO_VALUE_TYPE_INT;

input_arguments[0].value.v.i=10;





ProError
function_return = PRO_TK_NO_ERROR;





status = ProToolkitTaskExecute( handle, "User_Test_Task", input_arguments,
&output_arguments, &function_return );

------------------------------------------------------------ ----



After execution of ProToolkitTaskExecute
[/i][/b]call, value of status is set to PRO_TK_E_NOT_FOUND[/i][/b].



Before making the above call the
corresponding dll is successfully loaded into the memory using following API call
 
I checked with DLL Export View Freeware and found that "User_Test_Task" is not listed as exported function.

I have used PRO_TK_DLL_EXPORT to export the function.



Am I missing
something here?





Thanks,

Kashish
 
Did you set your preprocessor definitions correctly as in the sample make files?


WIN32;


_DEBUG;


_CONSOLE;


PRO_MACHINE=29;


PRO_OS=4;


USE_ANSI_IOSTREAMS;


PRO_USE_VAR_ARG;


PRO_USE_VAR_ARGS;


If I were you then I would start over and use the custom Pro/ENGINEER WF 3.0 Project Wizard for VS .NET 2003 from www.felcosolutions.com. You may be missing some critical C/C++ or Linker settings.

Hi Williaps,



Thanks for prompt responses and help.



It seems I am not using the correct options for building my

Hi Williaps,





Thanks a lot. PRO_OS=4; wasn't set. Now it's working fine.

Pro / Toolkit WF4.0 API wizard (Documentation available with WF4.0) suggest that the - ProArgument* input which is a ProArray of input arguments passed to the DLL shouldn't contain any ProValueData structure of type PRO_VALUE_TYPE_POINTER.

Can you suggest what wrong in supplying a pointer as input argument? Why shouldn't we send pointers? I checked it works fine.




Thanks,
 
I think the reason is that if you send a pointer to your external dll the memory location of where Pro/ENGINEER actually allocated the memory may change due to regenerations. You see, if you pass around a ProMdl object (event without an external dll) within your code, it may eventually crash your program with a memory access fault. It is better to pass around the ID and use Pro*Init() APIs to acquire a handle. Your program may have worked once but I wouldn't guarantee that it would work all of the time.
