What is the best way to test and log a Pro Toolkit?

[CHASEONHO]

I would like to develop an application that makes parameters easier to manage with the toolkit.

The development sequence I think is as follows.
1. Can I get information about the selected object?
2. Can I get subcomponents for the selected object?
3. Can I manage parameters for each object through a loop?

I have been in trouble since 1 step.
I wanted to get a model list of the session with the following code:

ProError TestProSessionMdlList()
{
 ProError status;
 ProMdl *mdl;
 int arr_size = 0, i;
 ProMessageDisplay(MSGFIL, "USER %0s", &arr_size) ; 
 status = ProSessionMdlList(PRO_PART,&mdl,&arr_size);
 if(status!=PRO_TK_NO_ERROR)
 {
   ProMessageDisplay(MSGFIL, "USER %0s", "Err") ; 
   return (-1);
 }
 else
 {
   ProMessageDisplay(MSGFIL, "USER %0s", &arr_size) ; 
 }
}

I want to make sure that the results from a particular function are correct.
I know that return returns a simple success failure.

Therefore, we want to check the result through ProMessageDisplay.

However, the output will be '&'.

Or any other suggestions?

Kind regards

Hello all,

chaseonho,

Assuming MSGFIL has a valid value, and a message file is good...

the posted code snippet cannot work ...

ProError TestProSessionMdlList()
{
 ProError status;
 ProMdl *mdl;
 int arr_size = 0, i;
 ProMessageDisplay(MSGFIL, "USER %0s", &arr_size) ; 
 ...

Here, you had initialized arr_size to zero, had taken a pointer to this variable, and used the pointer for ProMessageDisplay(...). The function expects a pointer to a character array, not a pointer to an integer... ProMessageDisplay outputs nothing because the dereferencing of this pointer evaluates to '\0'...

The next time you are trying to use ProMessageDisplay the situation is different:

... 
else
 {
   ProMessageDisplay(MSGFIL, "USER %0s", &arr_size) ; 
 }

the variable arr_size was set by ProSessionMdlList to some value, assuming there were models in session.

ProMessageDisplay expect a c-string (array of char), gets '&arr_size', thinks it is a pointer to a character array, dereferences the first (and only) array element and outputs the ASCII equivalent of whatever number was stored in arr_size variable. Then ProMessageDisplay would dereference the second element and so on until '\0' is reached. But you are not sending a char array in the first place and therefore ProMessageDisplay will output some random characters or crash Pro/E due to the buffer overflow...

You'll need to construct a c-string with a simplistic sprintf function and pass it to ProMessageDisplay.

{
char text[PRO_LINE_SIZE] = {'\0'};
sprintf( text, "%d", arr_size);
ProMessageDisplay( MSGFIL, "USER %0s", text);
}

HIH.

Yes you can use the message function, I would prefer the trail file.

Sample is for strings, in chinese this may differ!

void
UserLog(char* string)

{

 ProComment comment;
 ProStringToWstring(comment, (char*)string);
 ProTrailfileCommentWrite ( comment );

}

get the tail.exe for windows and use 'tail -f <path_to_trailfile>"
