And its running well before.I have a problem when I migrate my application from old development server to new one, FYI, my old server is windows server 2003 32 bit with oracle 10g, and my new server is windows server 2008 64bit with the same oracle version. I have set all configuration identically in both servers. using same database schemas, and same application.Overall, the application running well, but I was surprise when I found some error page while I running application in new server. error message is : ORA-00918: column ambiguously defined I don't know how the error happen, whereas in old server, no error at all with identically configuration.any one have same problem ?is it because 32bit & 64bit ?
View 1 RepliesI'm a newbie and I tried finding a solution of this error message:
"The model item passed into the
dictionary is of type
'NerdDinner.Controllers.DinnerFormViewModel',
but this dictionary requires a model
item of type
'NerdDinner.Models.Dinner'"
There are similiar problem error but not the same context problem. I believe that the problem is located in the edit.aspx and still i can't solve it.
DinnersController:
//
// GET: /Dinners/Create
public ActionResult Create()
{
Dinner dinner = new Dinner()
{
EventDate = DateTime.Now.AddDays(7)
};
return View(new DinnerFormViewModel(dinner));
}

control this hardware using a web site application or a simple web site
the thing to consider --> this is a class group project which we implement in c# asp.net.

Second thing is suppose my system is "A" and I wana send message to system "B" which is connected via a wire, so how the message flows on wire and how system "B" reads it from the wire ?
I can't see it nowhere in Visual Studio's Solution Explorer. The tutorial that I am following is using the Northwind database and hence the need to add the code line "using NorthWindTableAdatpter;" statement.So I thought I needed to add "using myDBTableAdapters" statement in my code which I did, but it's giving an error saying:
"The type or namespace name 'myDbTableAdapters' could not be found (are you missing a using directive or an assembly reference?)"
What's wrong? Where is the class for myDB's table adapter? I searched the .xsd file, but there's no mention of "myDBTableAdapters".It's not there in the Solution Explorer.

Is there some way I can install a database manager (like phpMyAdmin) using FTP? I think I've found the username and password but I'm not familiar with asp so it's quite a confusing system.

I have a need to add a new report to my page, the differnent parts of the page are all using a objectdatasource to populate the data. The new report because of all the data being returned i have started to use a repeater and a table in the ItemTemplate. Just binding the objectdatasource to the repeater works fine, but returns all the records and causes the page to be very long. I found this link for adding paging to repeater, but its setup different than what i have

Is there any way to use what i have already and add paging to the repeater?

I have one web part (the provider) which displays insurance claims in a gridview. When user clicks on one this value(case number) is passed via IWebPartField interface to another web part(consumer) which displays detailed info about the claim. So far so good. I can select different claims in the provider and the details show up in the consumer just fine. The moment I add a TextBox to the consumer, the consumer no longer recognizes the case number passed. I need the user to be able to enter a value in the textbox and click a button to update that claim info. I can debug and attach to process and it looks like it is getting the case in the callback function, etc, but when it is setting parameters for the stored proc in CreateChildControls, it is null. Comment out the TextBox and it works fine.
