ProParameterWithUnitsCreate returning PRO_TK_BAD_INPUTS

[MH_10366957]

Hello Community,

I am using ProParameterWithUnitsCreate, on Creo 9.0.2.0,to add a parameter to a model. However, everything I have tried to make it work has failed. 

The code I am using is below:

{

...

ProParamvalueSet(&testVal, p_value, new_value_type);

err= ProParameterWithUnitsCreate(&target_item, test, &testVal, NULL, &testInit);

...

}

target_item is a valid ProModelItem, test is a valid wchar_t*, testval is a valid ProParamValue, and testInit is an unitialized ProParameter. I have followed TestParams.c file to check if I did anything wrong, but it appears I have not. 

I have also looked at this article, Article - CS383949 - Creo Parametric Toolkit API ProParameterWithUnitsCreate() fails with error PRO_TK_BAD_INPUTS on specific machine (ptc.com), but it is unclear to me what registry file I am supposed to change the unicode_encoding to True on.

Does anyone have any idea as to why, with valid inputs, I am receiving the PRO_TK_BAD_INPUTS error?

Thanks,

Mark Hardebeck

The model item must have a name, if this is true, you may need to provide more code 😉

[MH_10366957]

TestNewParam(ProMdl target_model){

ProError NoConv;

ProModelitem  target_item;

ProParameter testInit ;

ProParamvalue testVal;

ProParamvalueType new_value_type = PRO_PARAM_STRING;

void* p_value;

wchar_t test[120];

char testc[120] = "Param";

NoConv = ProMdlToModelitem (target_model,&target_item);

if(NoConv != PRO_TK_NO_ERROR)return(-1);

ProStringToWstring(test,testc);

p_value = (void*)(wchar_t*)L"Include params";

ProParamvalueSet(&testVal, p_value, new_value_type);

NoConv = ProParameterWithUnitsCreate(&target_item, test, &testVal, NULL, &testInit);

...

This is a simple example from PTC. 

ProDrawing drawing;
    ProModelitem model_item;
    ProParamvalue param_value;
    ProParameter parameter;

    status = ProMdlCurrentGet(&drawing);
    status = ProMdlToModelitem(drawing, &model_item);
    param_value.type = PRO_PARAM_DOUBLE;
    param_value.value.d_val = 10.0;
    status = ProParameterWithUnitsCreate(&model_item, L"test", &param_value,NULL, &parameter);

For a string value use s_val, and copy using ProStringToWstring and PRO_PARAM_STRING for the type. For the Param name, same procedure.

Instead of „drawing“ use your ProModel (or Mdl :-))  „model“, same code, makes no different.

If this works, check the functions of ProParamvalue* and use them.

There are a lot of examples if you have toolkit installed.

I tried using your sample code, but I still received the same PRO_TK_BAD_INPUTS error.

Check your protk.dat/creotk.dat

ProParameterWithUnitsCreate() fails with error PRO_TK_BAD_INPUTS on specific machine.

Caused by unicode_encoding set to False in the registry file

Resolution: Remove the registry key unicode_encoding (or) set its value to True

Ah, thank you, I misunderstood what registry file meant on the solution that PTC provided. That worked for me
