view_as<DataPack>(dpHandle[i]).ReadString(cTableList[iArrayIdx], MAX_TABLENAME_SIZE);

dpHandle is "any" typed array which were sent by function callback.
and view them as DataPack for using methods.

but i got compile error message when i tries to compile this plugin.


// C:\Users\nickname\Desktop\script\include\umg/database.inc(154) : warning 215: expression has no effect
// C:\Users\nickname\Desktop\script\include\umg/database.inc(154) : error 001: expected token: ";", but found "."
// C:\Users\nickname\Desktop\script\include\umg/database.inc(154) : error 029: invalid expression, assumed zero
// C:\Users\nickname\Desktop\script\include\umg/database.inc(154) : error 017: undefined symbol "ReadString"

and i changed that into

DataPack dpData = view_as<DataPack>(dpHandle[i]);
dpData.ReadString(cTableList[iArrayIdx], MAX_TABLENAME_SIZE);

and all of errors are gone.

what's the problem?

[Starbish]

never mind. i found a solution.

just wrap once more with ().



sol)

view_as<DataPack>(dpHandle[i]).ReadString(cTableList[iArrayIdx], MAX_TABLENAME_SIZE);

change into

(view_as<DataPack>(dpHandle[i])).ReadString(cTableList[iArrayIdx], MAX_TABLENAME_SIZE);

The dpHandle[i] shouldn't need to be wrapped in parentheses...try view_as<DataPack>(dpHandle[i].ReadString(cTableList[iArrayIdx], MAX_TABLENAME_SIZE)); instead which should work "better" than the fix you found.

I don't even have to try that to tell you that you'll get an error about dpHandle[i] not having a method ReadString.

ReadString is a DataPack method, hence why you need the parentheses around dpHandle[i].

Perhaps I should read the first post next time instead of reading the last reply. Didn't even stop to think about what dpHandle could have stood for.

As far as i know, view_as operator must be used like this.

view_as<type>( var )

not this : view_as<type>var

[Wliu]

Yep, that's correct.
