I'll try to find more info regarding this point), and BLOB fields can contain binary data, but wxARG generates a member of wxActiveRecordRow-derived class (in my case it is TestRow class) whose type is wxString. Is it possible to change the data type of class members for BLOB fields to wxMemoryBuffer or maybe add some option to wxARG which should allow to change the data type for BLOB and/or TEXT fields? This would be helpful when storing/loading binary files to/from database.

Yes, sorry for that. I used wxString when I first design it and when I
want it to change to wxMemoryBuffer I noticed that DatabaseLayer didn't
had a SetParamBlob(int index, wxMemoryBuffer buffer), but I requested to
Joseph Blough and he added it. Somehow the feature was missed in my
todo-list.
So, I'have now commited the changes to the CVS but I have still not
tried the generated code. When I do I'll update a new release candidate
setup.exe for windows and sourcecode package.

Thanks for the bug report,
Regards, Matías.

PS: T-Rex, I've taken you as my beta tester ;). When you complete your
testing with wxARG might be a good time to make a stable release. I
don't test all the funtionallity in my project.
