vb.net - ADODB connection state property -


i working on old project of company, written in vb.net (with no try catch block in whole app * sigh *). basic problem leaves zombie process behind.

what suspecting db call using i.e. adodb connection object query sql database.

 adoconn.open("dsn=nameofdatabase;uid=nameofsa;pwd=password")

what thinking introduce simple check db state. using

adoconn.state (int)

but not sure possible values adoconn.state. have checked on https://msdn.microsoft.com/en-us/library/adodb._connection.state%28v=vs.90%29.aspx no information such.

i versed c# though

0: closed

1: connecting

2: connected etc.

any such information (with proper citation) helpful.

state property (ado) indicates applicable objects whether state of object open or closed. if object executing asynchronous method, indicates whether current state of object connecting, executing, or retrieving.

returns long value can objectstateenum value. default value adstateclosed.

constant            value            description  adstateclosed         0              indicates object closed. adstateopen           1              indicates object open. adstateconnecting     2              indicates object connecting. adstateexecuting      4              indicates object executing command. adstatefetching       8              indicates rows of object being retrieved.
