Create a new Model View Options

Jahidur — Mon, 20 Sep 2021 06:18:46 GMT

Hi,
In a custom Add-On i try to create a new custom Model View Options. Using the "ACAPI_Attribute_Get" i can get access the API_Attribute properties and in that properties i can get any specific Model View Options related properties. But when i try to use the "ACAPI_Attribute_Create" method to create a new Model View Options. I get an error (-2130313115 "The passed identifier is not a valid one, or valid, but not proper for the given operation.") . Is there any possible way to create a new Model View Options?

My current coding approach to do this task is given bellow .

API_Attribute attrib; API_AttributeDef defs; API_AttributeIndex ModelIndex; GSErrCode err; BNZeroMemory(&attrib, sizeof(API_Attribute)); BNZeroMemory(&defs, sizeof(API_AttributeDef)); attrib.header.typeID = API_ModelViewOptionsID; attrib.header.index = 3; err = ACAPI_Attribute_Get(&attrib); GS::UniString name = attrib.modelViewOpt.head.name; short temp2 = 0; char customName[API_AttrNameLen] = "New Custom "; strcpy(attrib.modelViewOpt.head.name, customName); // Set the new name err = ACAPI_Attribute_Create(&attrib, &defs);

Hi Jahidur,

I think to create a new Model View Option, you would also have to change the index. Right now you are retrieving an MVO with index=3 and then you try to create an MVO with index=3. So for the ACAPI_Attribute_Create function you should choose an index that is not already existing. I would try ACAPI_Attribute_GetNum and use an index higher than the count you get from that function.

Another error could be, that it could also be that MVO with index=3 is not existing so your ACAPI_Attribute_Get function already has an error and &attrib doesn't contain sensible data.

Hope this helps
