Syntax error in INSERT INTO statement for Access 2010

Prevent enabling of shift bypass – Access 2010

FileDialog doesn’t work

Convert Access image OLE Object into raw image byte array in C#
The problem here is that the imbedded image was not a simple BMP or JPEG. It was a Microsoft Word Picture and the OLE header information was considerably larger than the 300 byte window of the original GetImageBytesFromOLEField() code.

Is it possible to pass parameters programmatically in a Microsoft Access update query?
I just tested this and it works in Access 2010. Say you have a SELECT query with parameters: PARAMETERS startID Long, endID Long; SELECT Members.* FROM Members WHERE (((Members.memberID) Between [startID] And [endID])); You run that query interactively and it prompts you for [startID] and [endID]. That works, so you save that query as [MemberSubset]. … Read more
