Hi
I am trying to save images to an OLE Object field in Microsoft Access
with the following code, but i am getting a couple of compile errors :-
Could not find match for BlobField
LoadFromStream is not a member etc - I think this is because of the first
message
Code as follows :-
String pictureName;
TMemoryStream *stream = new TMemoryStream;
TBlobField *field = new TBlobField;
pictureName = "C:\\MC\\Images\\Tulips.jpg";
stream->LoadFromFile(pictureName);
field = dynamic_cast<TBlobField *>
(wDataModule->tPlants->FieldByName("JPGImage")); // OLE Object
field in Database
wDataModule->tPlants->Edit();
// wDataModule->tPlants->FieldByName("JPGImage")-> // commented out
// LoadFromStream(stream.get(), ftGraphic); //
commented out
field->LoadFromStream(stream.get(), ftGraphic);
wDataModule->tPlants->Post();
delete stream;
delete field;
Any help appreciated
