Archicad crashes after closing dialog box

[Anonymous]

Hi,

I've got working code for retrieving and displaying the amount of unique operators and targets of SEOs within a project. This works fine until I close the dialog box, and Archicad crashes. I've debugged and this is the error Visual Studio gave me:

Exception thrown at 0x000000000033203A in Archicad.exe: 0xC0000005: Access violation executing location 0x000000000033203A. occurred

Here's the code for getting the operators:

static int GetNumberOfOperators() {

	int size = 0;
	GSErrCode err = NoError;

	GS::Array<API_Guid>	allElements;
	GS::Array<GS::UniString> currentOperators;
	ACAPI_Element_GetElemList(API_ZombieElemID, &allElements);

	for (const API_Guid& guid : allElements) {
		GS::Array<GS::UniString> allOperators;
		API_Guid** guid_Operators = nullptr;
		Int32 nLinks;
		bool insert = true;
		err = ACAPI_Element_SolidLink_GetOperators(guid, &guid_Operators, &nLinks);

		if (err != NoError)
			continue;

		for (int i = 0; i < nLinks; i++) {
			GS::Guid nGuid = APIGuid2GSGuid(guid_Operators[0]);
			GS::UniString sGuid = nGuid.ToUniString();
			for (USize a = 0; a < currentOperators.GetSize(); a++) {
				if (sGuid == currentOperators)
					insert = false;
			}
			if (insert) {
				allOperators.Insert(i, sGuid);
				currentOperators...

The code for getting targets is pretty much exactly the same except for getting targets instead of operators.

Any help with this would be gratefully received.

Thanks

Hi,

This is the correct line:

GS::Guid nGuid = APIGuid2GSGuid((*guid_Operators));

Sorry, bbcode tricked me:

GS::Guid nGuid = APIGuid2GSGuid((*guid_Operators));

Hi,

Thanks for the reply, although unfortunately this didn't fix my issue. Is there anything else that could be the cause of the crash?

Thanks

Hi,

Then I guess the problem is not in this function. Could you please send me the bug ID from GSReport?

Thanks, Akos

P.S.: you can use a GS::HashSet instead of the GS::Array, then you don't have to check if the guid is already in there.

Hi,

Here's the bug ID:

Also, thanks for the suggestion to use GS::HashSet.

Thanks!

It hasn't showed up in our crash report database yet; did you send it in?

Best, Akos

Hi,

I've tried sending it again:

AC21-2019-07-30-11-04-47-2331

Cheers

EDIT: I've managed to solve the problem, as I was looking at the entirely wrong function. My output function had a memory error which was causing the problem. Thanks for the assistance anyway.

Hi,

This crash happens when your add-on is being unloaded, and its coming from your add-on. Maybe you free something twice?

SEO_Counter_Export.apx + 19243
C0000005 ACCESS_VIOLATION reading location 0xffffffffffffffff
