I lang tid har samarbejdsbranchen fokuseret på at forbedre enhedsfunktioner – bedre kameraer, klarere lyd og smartere software. Men den virkelige forvandling handler ikke om funktioner.
It is VERY important that you open the connection, then carry out some database operation and close the connection again. If connections do noty get closed then Access will fail!
Yes you can have more than one connection, but at some stage Access will fail if too many connections are open. Normally Access can have a theoretical max. of 255 users connecterd at one time. In practice this is far less! So, it is always best to close the connection as soon as you are finished using it. I can see you close the conn connection but where is OleDbCommand1 declared? If you are isng this for more than one operation then I can only guess that itis going to fail!
