I have a program that connects to an ODBC tables (3 of them) and I use select .... Left join etc Where ... etc. The issue I have is the connection takes about 20 to 25 seconds to complete. I'd like to create some status message so the user knows the system is not actually hung. Using Visual Studio 2010 Ultimate, VB.NET, ADO 2.7.
View 1 Repliesi want to ask what is the difference between oledb connection and odbc connection. I have a case, my office used ncomputing then i have to developed an application using sqlserver 2000 and vb.net 2005, i used oledb connection. When i try to implement it in ncomputing, why user must has admin access level and dbo level in sql server, it seems trouble when all users are admin. But there's a rumor that when using odbc connection, we dont need to give admin access level for users.es.

1. How can I create a progress bar that will indicate the status of the transfer?
2. If the remote path is not available, how can i easily alert the user that it is unavailable. Currently it returns an exception but it took a lot of time to return this message..
i wanted to update my status to indicate e order is delivered or progress in my database and the form itself. so i decided to use progressbar. but im not sure how the coding going to works. or is there other alternatives suggestions on how im going to update my status?
View 13 RepliesGot a bit of a weird problem with a progress bar. I'm using a backgroundworker, which calls a "Process" function in a different class. The function goes about its business, and sends an update back to the form displaying the progress bar. What I'm finding is that its doing everything right, except update the progress and a label on the form. I've put breakpoints in to check the values of variables being sent to the form, and they're correct. I've also checked the value/maximum of the progress bar during the same break as I step through, and they're being set correctly.
they're just not displaying their updated status. I've tried refresh and application.doevents, to no avail. When the backgroundworker is complete, the values of the progress bar/label are as if I've never touched them! When the worker is complete, the Close button is enabled, so I know its finished. Anybody got any pointers/thoughts on this because I've been battling with this for a day and a half so far. I'm using the same technique as I've used elsewhere in the app to do similar backgroundworker progress updates, but this one refuses to work properly.
I'm using ODBC to export tables from a dataset to an Excel file without auto-formatting Excel or even needing to have Excel installed on the users PC. This works great but I just had a request to autosize the columns and make the header line bold. The only way I know of doing this is to fully automate Excel to control the row/column/cell formatting. Does anyone know a way of doing this without auto-formatting Excel?

I'm trying to connect to a database and keep the connection open for any amount of user activity/queries within the database. Currently I have a connection that opens and closes for any query (save, update, etc...) which requires the logon process to the back-end every time the user saves etc... Is there a way to simply connect and leave the connection open so there won't be a lag time when running the query due to the logon process? This is what I'm using:

Q1: Why I cannot create New Excel.ODBCConnection? I have this

Dim wb As Excel.Workbook

Maybe because it is read only. I want that because the ms query is hardcoding the path of the access db even if i choose DSN so, if I change the location of the access file the query in the excel will not work, Q2: How I can change the connection in the Excel sheet?

I'm trying to develop a simple app with vb.net in VS 2010 that could monitor the ODBC connections via DSN made on the macnhine running this app.My scenario is an application (non Vb) running on a workstation that connects to an MS Access database on a network share.
The application (non Vb) connects using a link (ODBC connection via Oracle 10G) to the tables on the Oracle side.My VB.net Application should monitor the machine running the main application for ODBC connections drops and alert me via email for example.My question is where in the framework can I find something to instantiate or reference in order to check ODBC connections states constantly as well as network disconnection issues as well so I can log and /or alert when possible for network problems and ODBC connection problems for all the applications that might run on the host (machine running my vb app).

I'm using Visual Studio 2005 Pro. I have an ODBC (not OLEdb) Connection to a spreadsheet. Works fine except the first row is missing. How do I stop this behavior? I can see that for OLEdb there is a way to suppress this behavior using the HDR=No parameter in the connection string. When I try that for the ODBC connection, No change. Row Still Eaten. I also went to the HKLMSoftwareMicrosoftJet4.0EnginesExcel registry key and changed the FirstRowHasNames value to 00. No change. Row Still Eaten.
