Solved Check if Access is in use

8 posts in this topic

#1 ·  Posted (edited)

I am using the attached file to build a connection to MS Access. This is part of an application I am building and we are using Access just as a proof of concept. The issue I am having is occasionally two people are trying to write at the same time. Is is possible to see if Access is in use before proceeding?

I found what I needed.

$conn.State = 1

Actually I was wrong it will still fail on $conn.Open($DSN) and I cannot check the state until it is open.

What is the value of @error and @extended after the connection fails? Usually this tells you what went wrong.

First off Water big fan. Thanks for taking a look at my question. 

I have not used  @error and @extended so I hope I am using them correctly. I added like this.

$conn.Open($DSN)
If @error Then MsgBox(0,"",@error & @CR & @extended)

I get back:

If you are in the beginning, try my ADO.au3 UDF (look in my signature), It will allow you to save a lot of time and trouble.

Thanks mLipok. Seeing how you handle the error checking when opening the connection is what I needed.
