InDesign Library - Block Addition of Frames

[Rahul_Rastogi]

Hi,

I want to block addition of frames to InDesign Library. (*.indl).

I am observing kSnippetBasedCatalogBoss and catpure the command kLibraryAddItemCmdBoss with message kBeforeDoMessageBoss.

From kLibraryAddItemCmdBoss, I am able to identify which frames are being added by the user and I can decide whether to block the addition of frames or not.

From Observer, I set ErrorUtils::PMSetGlobalErrorCode(kCancel) when kLibraryAddItemCmdBoss &&  kBeforeDoMessageBoss command is executed.

The above method works and it doesn't allow frame to be added in Library.

But then it display the following message as shown in the screenshot -

I don't want any message to be displayed.

I also tried the following -

1. With kLibraryAddItemCmdBoss, we have ICopyCmdData interface, from where I get IDataExchangeHandler and call IDataExchangeHandler->Clear().

InDesign still displays the error message.

2. I added my own error ErrorStringService and passed my own error in ErrorUtils::PMSetGlobalErrorCode(kMyErrorCode) but then InDesign Crashes.

Am I observing correct boss class kSnippetBasedCatalogBoss and obsering right command kLibraryAddItemCmdBoss ?

Can anyone help me on this ?

Regards,

Rahul Rastogi

Found the solution -

 if(::GetClass(iCommand) == kLibraryAddItemCmdBoss && theChange == kBeforeDoMessageBoss)
{

InterfacePtr<ILibraryCmdData> iLibraryCmdData(iCommand, IID_ILIBRARYCMDDATA);
if(!iLibraryCmdData)
break;

iDestLibrary = iLibraryCmdData->GetDestLibrary();
}
else if(::GetClass(iCommand) == kLibraryAddItemCmdBoss && theChange == kAfterDoMessageBoss)
{

InterfacePtr<ILibraryCmdData> iLibraryCmdData(iCommand, IID_ILIBRARYCMDDATA);
if(!iLibraryCmdData)
break;

AssetIDList assetIDList = iLibraryCmdData->GetAssetList();

Utils<ILibraryCmdUtils>()->ProcessLibraryDeleteItemsCmd(assetIDList, iDestLibrary);

// set the global error to kSuccess otherwise InDesign displays message "disk is full".
ErrorUtils::PMSetGlobalErrorCode(kSuccess);

}
