How to List working directory file names (with checkbox) in creo UI

Hello, I want to show current working folder files in UI with individual check box.

Here I tried below code, but its not working. Any one has solution to this?

void Assymode::StartAssy(ProMdl assyMdl)
{

ProError status;

ConvertParttoStep();


return;
}

void ConvertParttoStep()
{
ProError status;
int iDiaout;
ProPath *files_list, *dir_list;
int num;

status = ProArrayAlloc(0, sizeof(ProPath *), 1, (ProArray*)&files_list);
status = ProArrayAlloc(0, sizeof(ProPath *), 1, (ProArray*)&dir_list);
status = ProFilesList(NULL, L"*.prt,*.asm", PRO_FILE_LIST_LATEST, &files_list, &dir_list);

if (status == PRO_TK_NO_ERROR)

{
status = ProArraySizeGet((ProArray)files_list, &num);
wchar_t **model_names;
char **strings;
status = ProArrayAlloc(num, sizeof(wchar_t *), 1, (ProArray *)model_names);
status = ProArrayAlloc(num, sizeof(char *), 1, (ProArray *)&strings);

for (int i = 0; i < num; i++)
{

model_names[i] = (wchar_t *)calloc(PRO_MDLNAME_SIZE, sizeof(wchar_t));
strings[i] = (char *)calloc(PRO_MDLNAME_SIZE, sizeof(char));

status = ProMdlMdlnameGet((ProMdl)files_list[i], model_names[i]);
ProWstringToString(strings[i], model_names[i]);

}
status = ProUIDialogCreate("List", "List"); // Add UI to creo memory
status = ProUIPushbuttonActivateActionSet("List", "CommitOK", (ProUIAction)UIOKPB, NULL);
status = ProUIPushbuttonActivateActionSet("List", "CommitCancel", (ProUIAction)UICloseAction, NULL);
status = ProUIListNamesSet("List", "List1", num, strings);
status = ProUIListLabelsSet("List", "List1", num, model_names);
status = ProUIDialogActivate("List", &iDiaout); // DIsplay UI in Creo
status = ProUIDialogDestroy("List"); // Delete UI from Creo memory
status = ProUIDialogCloseActionSet("List", (ProUIAction)UICloseAction, NULL);

status = ProArrayFree((ProArray*)&files_list);
status = ProArrayFree((ProArray*)&dir_list);
status = ProArrayFree((ProArray*)&model_names);
status = ProArrayFree((ProArray *)&strings);
}

return;
}
ProError UIOKPB(char *dialog, char *component, ProAppData data)
{
ProError status;

status = ProUIDialogExit(dialog, 0);
return status;
}
ProError UICloseAction(char* dialog, char* component, ProAppData appdata)
{
ProError status = PRO_TK_NO_ERROR;

ProUIDialogExit(dialog, 0);

return status;
}
