I want to put the ID value in C++ while creating Beam.

I want to put the id value in C++ while creating Beam.
What should I do?
I created it by looking at the create element_test code.

What can I study?
I'm a beginner who can understand if you give me the code. ^^

1. Solved: Get element's ID - Graphisoft Community

[ReignBough · Accepted solution]

Is this what you need: ACAPI_Database(APIDb_ChangeElementInfoStringID, ...)?

[LeeJaeYoung]

GSErrCode ACAPI_Database(APIDb_ChangeElementInfoStringID,element.header.guid, "ABC111");

err = ACAPI_Element_Create(&element, &memo);

if (err != NoError) {

ACAPI_WriteReport("ACAPI_Element_Create (Beam) has failed with error code %ld!", true, err);

}

I'm a beginner so I don't understand because I don't have the code.
I need a code that can change the ID value.

1. I'm curious whether it's before or after creation and why the error occurs. ^^

1. 

err = ACAPI_Database(APIDb_ChangeElementInfoStringID, &element.header.guid, "xx");

if (err != NoError) {

ACAPI_WriteReport("ACAPI_Element_Create (Beam) has failed with error code %ld!", true, err);

return;

}

err = ACAPI_Element_Create(&element, &memo);

if (err != NoError) {

ACAPI_WriteReport("ACAPI_Element_Create (Beam) has failed with error code %ld!", true, err);

}

2.  archicad is dead

err = ACAPI_Element_Create(&element, &memo);

if (err != NoError) {

ACAPI_WriteReport("ACAPI_Element_Create (Beam) has failed with error code %ld!", true, err);

}

err = ACAPI_Database(APIDb_ChangeElementInfoStringID, &element.header.guid, "xx");

if (err != NoError) {

ACAPI_WriteReport("ACAPI_Element_Create (Beam) has failed with error code %ld!", true, err);

return;

}

You need to call your routines inside ACAPI_CallUndoableCommand()  block. 

[LeeJaeYoung]

 err = ACAPI_CallUndoableCommand("Create Beam",
[&]() -> GSErrCode {
return ACAPI_Database(APIDb_ChangeElementInfoStringID, &element.header.guid, "xx");
});

The id value did not change to "XX".

 err = ACAPI_CallUndoableCommand("Create Beam",
[&]() -> GSErrCode {
return ACAPI_Element_Create(&element, &memo);
});

The following error occurs.

[LeeJaeYoung]

thank you so much. ^^

I understand now. ^^

[LeeJaeYoung]

err = ACAPI_Database(APIDb_ChangeElementInfoStringID, &element.header.guid, &na);

 

ACAPI_Database not found in archicad 27 api
There is also no content in ACAPinc.h.
What should I study?

And I don't have apidevkit.chm, where should I search for it?

Check migration documentation and ACAPI_MigrationHeader.hpp inside Support\Inc folder

Use  ACAPI_Element_ChangeElementInfoString() instead of ACAPI_Database(APIDb_ChangeElementInfoStringID...)

[LeeJaeYoung]

Thank you for your advice.^^

Have a happy weekend.

When functions/structures were changed in SDK (and we used them), we put them in a function wrapper to call the proper functions/structure member. Especially, when we support the lower versions of ArchiCAD.

Example:

GSErrCode Db_ChangeElementInfoString(API_Guid* guid, GS::UniString* id)
{
    if (ARCHICAD_VER >= 27)
         return ACAPI_Element_ChangeElementInfoString(guid, id);
    else if (ARCHICAD_VER < 27 && ARCHICAD_VER >= 23)
        return ACAPI_Database(APIDb_ChangeElementInfoStringID, guid, id);
    else //if (ARCHICAD_VER < 23)
        return APIERR_NOTSUPPORTED;
    //return NoError;
}

void Elem_SetElemType(API_Elemennt& elem, API_ElemTypeID typeId)
{
    if (ARCHICAD_VER >= 26)
        elem.header.type.typeID = typeID;
    else //if (ARCHICAD_VER < 26)
        elem.header.typeId = typeID;
}

 ARCHICAD_VER is then defined in Project Property's Preprocessor.
