Delphi OLE - How to avoid errors like "The requested member of the collection does not exist"?
- by Edwin
Hi,
I'm automating Word with Delphi, but some times I got an error message:
The requested member of the collection
does not exist
It seems that the Item member of the Styles collection class does not always exist and some times causes the above mentioned error. My workaround is to catch the exception and skip it, but is there anyway to detect it instead of using the try...except block? The problem with the try...except block is that when debugging the raised exception is annoying...
My code example:
var
aWordDoc: _WordDocument
i: Integer;
ovI: OleVariant;
wordStyle: Style;
begin
for i := 1 to aWordDoc.Styles.Count do
begin
ovI := i;
try
wordStyle := aWordDoc.Styles.Item(ovI);
except
Continue;//skip if any error occurred.
end;
//do something with wordStyle
end;
end
