Access :: Create A Simple Web Form To Query Database?
Jun 8, 2010
I'm new here and really, new to asp.net except the very basic things.
I am trying to create a very simple (I think simple) web form with five textboxes and three dropdown boxes and one submit button. The user enters information in the textbox fields and selects from the dropdown lists (which are populated from the database), hits enter and the database runs the query and returns information on a separate page (or can it return to the same page via panels?) The original page returned to a separate page using server transfer.
I have this page already existing in asp but feel that it would be much better served in asp.net.
Can someone point me to a post where I would guess this has been answered many times?
How do I submit the new data to the database, update the records and return the query?
I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).
Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?
I am looking for a simple (or best practice) way of pre filling some of the fields in a create form. As an example, say the create view is loaded for a model that has a datetime field. I want the textbox for that field to be filled with DateTime.Now. I don't need a javascript watermark or anything like that, I jsut want to pre fill the text box.
The GET version of my Create method in the controller just returns the view with no model so I am not sure where to set this value.I've beel trying to figure this out for a while and I must be missing something, I expected this to be really easy.
I'm trying to create a simple contact form for a website and cannot figure out how to properly configure it. I have a simple code I got off a tutorial (VB), that I pasted inside my Contact.aspx code-behind-page:
[Code]....
It brings up errors everywhere (declarations expected, etc) in the code-behind-page. I'm new to VB so I don't know what I'm missing. The above code is exactly the content in my code-behind. Does anyone know what I'm missing?
I am a .net developer.I am not that strong in SQL.I need a simple query.This is from Northwind Database.
select 'Select All' as CustomerID,'Select All' as City union(select CustomerID, City from Customers order by City)
i need to get output like 1st row should be Select ALl Select All and next rows should be output of this stat..(select CustomerID, City from Customers order by City)
i am not getting this...i can do by keeping the second query result in temp table and then using union... but i am looking without temp tables or simple query.
I have a data type mismatch while inserting into a number field in an access database using a parameterized query.I think this should be pretty simple but I am still learning a lot.
[Code]....
I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.
am a bit unsure of the best way to go about this. I have a form where data is entered, date ranges, usernames, passwords etc and when the button is pressed on the form it searches a database and returns values which match the values entered.I can't think of the most efficient way to do this, could anyone give some pointers on where to start?I thought perhaps of writing a query and then just putting in the variables which pick up the entered values and reading it all in as one big string something like:
SELECT * FROM DB WHERE ProductID = "DateTxtBox" & "NameTxtBox"
I haven't checked the syntax but this is just to give you a idea of what I am thinking.
Have a simple Comments form syntax with CSS, so that a person can leave his/her name, e-mail, subject and comments. the form that can write under the question when Reply is pressed by the person.
I am trying to create a DataReader to return a counted value from an Access Database. It all works if it finds some rows, but falls apart when there is no total.
My code is as follows (highlights);

I have created a simple application to edit data in an access database using gridview but its not working , the results are shown correctly , but when i click update nothing happens..
i have a problem executing an insert query. whenever i try to insert i have an exeption telling me it cant execute because a record needed in another table; where i select a value form that other table according a listbox, and then insert it into this table. here is a sample of my code:
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|emp2.mdb");
int a = 0; conn.Open(); string sqlcmd = "select id from nationality where descreption = '" + DropDownList1.Text + "'"; OleDbCommand readNatCmd = new OleDbCommand(sqlcmd, conn); OleDbDataReader readerNat = readNatCmd.ExecuteReader(); while (readerNat.Read()) { a = readerNat.GetInt32(0); } readerNat.Close(); conn.Close(); string saveEmpcmd = @"insert into employee " + "(nationality) " + "values (@nationality)"; OleDbCommand objCmd = new OleDbCommand(saveEmpcmd, conn); objCmd.Parameters.AddWithValue("@nationality", a); conn.Open(); objCmd.ExecuteNonQuery(); conn.Close();
now, the form executes with no errors, but it catches an exeption caused by the ExecuteNonQuery funtion; here it is in details:
System.Data.OleDb.OleDbException: You cannot add or change a record because a related record is required in table 'nationality'. at System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(OleDbHResult hr) at System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS dbParams, Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteCommandText(Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteCommand(CommandBehavior behavior, Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteReaderInternal(CommandBehavior behavior, String method) at System.Data.OleDb.OleDbCommand.ExecuteNonQuery() at Default2.Button1_Click(Object sender, EventArgs e) in c:Documents and SettingsAdministratorMy DocumentsVisual Studio 2005WebSitesempDefault2.aspx.cs:line 305
when i remove the relation between the tables, the exeption isnt catched anymore, but the value stored in the employee table is 0 how can i solve this?
where I'm going wrong with this SQL Query of an Access Database which populates a Datagrid,
From a calendar selection the user can select a From and To Date and I want the SQL Query to ONLY pick up the dates between these two values, the selection is fine it seems to be the sql query which is the problem ... (I have added dates rather than the text value to make it easier to get working ) the following query wil pick up dates outside of the selected values 01/08/2010 , 02/08/2010, etc
SELECT COUNT(*) AS Date_Installed, Date_Installed AS Expr1, Installed_By FROM Buildprocess WHERE (Date_Installed BETWEEN '20/08/2010' AND ' 25/08/2010') GROUP BY Date_Installed, Installed_By

I created a Class library for WCS service (MyWCFServiceLibrary) to access data form my database. The database connection strings have been defined in Properties->Settings.settings. The endpoints are defined in the app.config. Tracing and logging is set to write to files on local server. This service is hosted by a .net web service. This webservice refrences the WCF service using MyWCFServiceLibrary.dll and MyWCFServiceLibrary.pdb. The web service is hosted in IIS. All this setup is working fine on the development environment.Now I want to deploy this in the QA environment. Since I am a newbie with WCF, I would appreciate some help on what needs to be done for deploying this on the QA server.1. Do I need to recompile the MyWCFServiceLibrary.dll after changing the connectionstring to point to QA database and tracing and loggint paths to the new server?2. Is there anything that needs to be done with end points or anything else?
