API Module DATA Manager

Anonymous
Not applicable
Hello,

I need help to use API developper kit. I use Visual Studio (on Windows).

My goal :

I aim to write a plugin for archicad 12 which load an external Hotlinked Module and paste it on the scene, like if in Archicad we do : file -> External content -> Place hotlinked Module -> choose Hotlink (module file and select "open in single story mode") and place Module.


My researches :

I found the Module Data Manager module, I think that's what I need to use but I'm not sure.
they speak about an exemple but it's not in the exemple folder of API v12.
I found this exemple in the examples pack for archicad 7 but the API is very old and too many things have changed to build it.



So, if somebody could help me please i really need help because it's difficult to understand how to use this module.

Than you and sorry for my english, i do my best .

I think you have been looking at the ModulData Manager, which allows an add-on to store and retrieve data in the project file, e.g. user preferences. These functions don't have any direct relevance to the problem.

I haven't attempted to place hotlinks in a project, so I can't definitively say that it will work, but I recommend you look at the following subjects in the Devkit documentation:
  • - API_HotlinkTypeID
    - API_HotlinkStoryRangeID
    - API_HotlinkUserData
    - API_HotlinkNode

thank you,

you're right this subjects seems to be what I'm looking for.
So, I have to fill the API_HotlinkNode structure with the 3 others and other parameters.
But once the structure is filled, will the modul be pasted automatically to the scene?

Thank you very much for your help.

Sorry, I don't know the answer that. These functions are new with AC12 and I haven't had any need for them yet. Experiment a bit and let us know what you find. Someone like Akos could probably tell you more.

Hello,

i continued to search for my issues and I found something which seems to be good :

- I fill this structure : API_HotlinkNode
(even if I do not succeed to fill many of parameters) :
BNZeroMemory (&myAPI_HotlinkNode, sizeof (myAPI_HotlinkNode));

	//fill API_HotlinkUserData structure
	myAPI_HotlinkNode.userData.dataVersion=1;
	myAPI_HotlinkNode.userData.platformSign= GS::Act_Platform_Sign;

	//define single story mode
	myAPI_HotlinkNode.storyRangeType = APIHotlink_SingleStory;
	//define file type
	myAPI_HotlinkNode.type = APIHotlink_Module;
	//define file to load
	myAPI_HotlinkNode.sourceLocation = &location;

	//define update date
	myUpdateDate.year = 2008;
	myUpdateDate.month = 12;
	myUpdateDate.dayOfWeek = 4;
	myUpdateDate.day = 4;
	myUpdateDate.hour = 10;
	myUpdateDate.minute = 0;
	myUpdateDate.second = 0;
	myUpdateDate.milliSecond = 0;
	
	err = TIGetGSTime(&myUpdateDate,&myAPI_HotlinkNode.updateTime,TI_UTC_TIME);
	
	if (err != NoError) {
			sprintf_s (msgStr,sizeof(msgStr), "TIGetGSTime: %d ",(int) err);
					ACAPI_WriteReport (msgStr, true);
			return err;
		}

	//other parameters
	myAPI_HotlinkNode.refFloorInd = ind;
-use this fonction :
ACAPI_Database (APIDb_CreateHotlinkNodeID,&myAPI_HotlinkNode,NULL,NULL);
and i use this one :
ACAPI_Database (APIDb_CreateHotlinkNodeID,&myAPI_HotlinkNode,NULL,NULL);
I think that's the good way, but the last one creates a "APIERR_GENERAL" error code, i think that's because I do not succeed to fill many parameters in the sturcture.

If someone know where is my error, that would be the biggest Christmas present oh this year

Have you tried enclosing your code between ACAPI_OpenUndoableSession and ACAPI_CloseUndoableSession? Some functions return that error if you haven't started an Undo session.

Hello,

yes, i already enclosed my code between these functions.
I think this error comes from the fact i did not fill these three parameters in the structure:

GS::uchar_t name [API_UniLongNameLen];
GS::uchar_t refFloorName [API_UniLongNameLen];
GSType ownerId;

because I don't understand what are GS::uchar_t and GSType, so these parameters are important.

I tried this :
res = CHANSI2Unicode ("Module1", GS::CStringLen, myAPI_HotlinkNode.name,API_UniLongNameLen, CC_Default, NULL);       
	res = CHANSI2Unicode ("1", GS::CStringLen, myAPI_HotlinkNode.refFloorName,API_UniLongNameLen, CC_Default, NULL);   

	myAPI_HotlinkNode.ownerId = 1295081318;
But i'm not sure at all.

I haven't made any use of these functions yet, and the documentation is a bit thin. I think the best option is to PM Akos Somorjai - he is the API guru at GS, and has answered more than a few awkward questions for me.

Ok,

i send him a PM, i'm waiting for his aswer.
I continue to search and I'll let you know what i find.


thank you

hello,

I succeeded to solve my error, i just had to do this :
myAPI_HotlinkNode.refFloorInd = -2;
instead of this
myAPI_HotlinkNode.refFloorInd = 1;

Now my module is saved in archicad, i now have to place it.

i will succeed , i don't lose hope.
