Setting Up IIS With System.Data.OracleClient?

Mar 4, 2010

I have a web application that connects to a Oracle 10.2g database. If I'm running my site in the Visual Studio 2008 webserver everithing is ok, but when a publish it in IIS a get "System.Data.OracleClient requires Oracle client software version 8.1.7 or greater".

I added all the permissions for the ASPNET, Authenticated Users and even Everyone but still doesn't work.

I have no idea what else to try. It seems clear to me that this is an IIS issue as the site works well in VS2008 integrated webserver. I'm using IIS 5.1.

Databases :: System.Data.OracleClient.dll Deprecated?

Nov 12, 2010

I have a web application that has been using the System.Data.OracleClient.dll for the past 3 years. Recently we've been having some performance issues on the database server and it appears that this app is now causing problems when connecting to our Oracle database.I've found an updated client at the Oracle website: question is: Is it necessary for me to update to this new client?We are running Oracle 11g on 64-bit servers in a cluster.The app is running on a Windows Server 2008 R2 64-bit machine using ASP.NET 4.0. The app was built using Visual Studio 2005 Team Suite on a 32-bit machine. It was re-compiled on a 64-bit machine and imported into Visual Studio 2010 Professional in order to switch the target framework to .NET 4.0. Then it was deployed to the server. This basically updated the Web.config file for us, the rest of the site remains the same as before.

Databases :: Getting Error System.Data.OracleClient Requires Oracle Client Software Version 8.1.7?

Jul 20, 2010

Getting the following error when browsing .net 2.0 application System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.

I have setup a .net 2.0 application with oracle backend on windows server 2008 R2. I have oracle client 11g installed on the server for the application to talk to the oracle database. This worked well when the .net 2.0 application was hosted on windows server 2003 and oracle client 10g. But when it is hosted on server 2008 with new oracle client it is giving the above error when browsing the page. This error occurs when the connection is opened inside the c# code.

Forms Data Controls :: GridView Alternative - Facilitating Data Input

Mar 5, 2010

I have been using Gridviews throughout a website I am currently building, however one particular requirement is to display two tables side-by-side that butt up against each other for the purposes of data entry. One person inputs numerous entries on the LH table whilst a different person will respond to one or more rows in any particular order (ie row 2 may addressed but row 1 might stay blank for a period of days). As far as I am aware, a GridView (or two) won't suit this requirement for the reason (from my still new understanding of GridViews) of not providing the ability for a 'respondee' to address any row in any particular order. Whilst I could add a button to each GriView row which displays a detailsView/FormView horizontally in line, I would still have to populate the Gridview with empty rows for those rows not addressed plus this 'fudging' just doesn't bode well concerning DB management.

It just seems adding two asp tables side by side then somehow working out how to automatically present a new row for data entry for the left hand table and creating a second table being the same size as the first (according to its number of rows) would be the way to go, then the task of data gathering/uploading to the DB. How best address the requirement - there maybe better ways for facilitating data input as opposed to using side-by-side controls, however it is the clients request. Also I don't want to go expelling copious amounts of time to fully customize a gridview when simply creating some sort of dynamic table would be sooo much quicker and easier for this once off. I have tried some searching, however not knowing where to start is problematic as 99% Google results return GridViews (as you would expect).

C# - Alternative To Query Strings To Pass Data Between Webpages?

Jan 20, 2010

I am currently using a number of query string parameters to pass some data from one page to a second page (the parameters hold confirmation/error messages to display in the second page), that due to a third party product can no longer work correctly in the production environment. The user completes an action on the first page, and is then transferred to the second page. What are the possible alternatives to use instead of a query string and GET - session variables, POST data, or something completely different?

Forms Data Controls :: Creating Alternative Text For URL In Gridview

Jun 30, 2010

I created a database with ID, Title, Content, Date, ImgLnks, Image and Imagecaption and i'm using ObjectDataSource to populate the data. The field "ImgLnks" displays a new blank window with URL. This column is entered as text, inserted into the database and displays as clickable link in the gridview. My question is, is there a way that I can put an Alternative Standard Text in this column instead of displaying the clickable link like [URL] etc.? Text like, "Visit Page".

Creating Dynamic DataList Controls With ID's Based On Bound Data - Finding Alternative

Jun 28, 2010

As a workaround for the fact that asp:Checkboxes don't have values, I am attempting to dynamically create the ID's of checkboxes in a DataList so that it inserts the primary keys into the control ID. This is surprisingly difficult.

I have placed a PlaceHolder in my DataList ItemTemplate, then in the ItemCreated I create the checkboxes using string.Format("Checkbox{0}", DataBinder(e.Item.DataItem, "ID")). The problem is that this only works in a non-postback condition, as on postback the DataItem is null. And of course ItemDataBound isn't called on PostBack so that won't work either.

I can't seem to find a good way to handle this short of if (IsPostback) dataList.Bind(), which i don't think is a good way to do it.

Can anyone provide me with any alternatives here?

Alternative For Tables?

Feb 14, 2010

One of my classes currently is a C# class. I was given a small assignment for creating a bare-bones Facebook clone. I am now ready to list wall posts on user's pages.Having just been taught about DataLists (using tables), I thought I'd use one. However, I'm told "The messages list must be displayed without using table tags (<table>, .<td>, etc.)"

This is not really a coding question, just asking for a recommendation on how I should go about displaying posts without tables while still easy on the eyes (including name, the poster's picture, the message, and a date).
