Re: [GENERAL] connecting VB to postgreSQL
In any case, it's obvious in your screenshot that you left the server and location fields blank in the connection setup form. This is most likely the cause of your problem. *doesnt work either..OLE-DB error persists. thanks for the readmefile. * On Wed, Apr 9, 2008 at 8:04 PM, Craig Ringer [EMAIL PROTECTED] wrote: Abhishek MANDHANA wrote: Did 30 seconds search worked ? for me its didnt ?

Re: [GENERAL] connecting VB to postgreSQL
Hi Richard, is it possible to check them individually how ? well..!! I think it has something to do with settings. couldnt even add a connection because once i click ok, it show the OLE-DB error, so no question about executing statements.. In tried with mdb database it works. Found some more help. http://support.microsoft.com/?scid=kb%3Ben-us%3B269495x=9y=10 Please see a snapshot of settings i could change .. The above help file also speaks about Connection string (FILENAME). Any idea how this setting is to be done if necessary for adding a postgresql connection. Please reply.

You're still not telling us what the error message is when you try to connect. I don't use .net, but if you write code to connect to any database then the connect method/function will return some sort of status code to indicate success or failure. There will then be a way of getting a precise error code and message. I'm assuming you can connect from this machine using psql and/or pgadmin, yes? I'm assuming you've turned on connection logging at the server and have checked to see what's happening there, yes?

Re: [GENERAL] connecting VB to postgreSQL
Hello, In brief. TASK : Write a code in VB so that i can connect to postgreSQL and then execute some stataments from my VB application. I didnt want to code it ..I found the other way round very similar but without coding. Visual basic has a server explorer .. which can be used to connect to various database(Eg:Access database,mdb or in our case postgreSQL) and then you can execute the SQL statements in VB, now once you open Server explorer you need to ADD/Create/setup a A CONNECTION TO DATABASE which you want to use., i.e. setup a connection to postgreSQL. now my first 2 posts speak about this setup and problem/error i had while setting up connection..it gives OLE-DB error which we already spoke about..STILL UNRESOLVED. All goes around setup required to connect to postgreSQL using VB ,Server Explorer. I need the settings to be done in Server explorer , so tht i could connect to postgreSQL...please see snapshots from first posts..That is all you will neeed.you will understand it quickly now i hope..I know this speaks much around VB but you need to know why OLE-DB error occurs when you connect a database? I have found another way to connect , still i need to check its surety, hopefully tomo it works I hope this helped you understand me better , please reply if you find any solution. I will again post update about it tomorrow., but if this works it would be gr8 atleast for me ;-) I'm assuming you can connect from this machine using psql and/or pgadmin, yes? Yes richard , I am able to connect I'm assuming you've turned on connection logging at the server and have checked to see what's happening there, yes? Yes i turned it on and it helped me to find out the other method , Thanks. Thank you Abhi No idea. You're still not telling us what the error message is when you try to connect.

Re: [GENERAL] connecting VB to postgreSQL
Did 30 seconds search worked ? for me its didnt ? Please just dont test the connection, the applet shows Connection successful , Are you able to create it and see it under Server Explorer?
