DataSource Controls :: Adding 2 Fields Together And Inserting Into A Database?
Jul 6, 2010
I have an SQL datasource that successfully enters customer details into a table. What it includes is the persons address. First of all we add the persons address, then we add the persons name to that address in a seperate physical procedure. i.e. on a different form.
What I need to do is try and stop users entering the same address twice. The way I have thought of doing this is by making a string field called AddressIdentity and have this contain the door number and the postcode of the address with all the spaces stripped out. Then when adding the address, it checks if this exists before adding it. However I cannot work out how to put the 2 fields together without using the codebehind file, which I don't mind doing if I need to, but I'm sure its avoidable.
Here is my code - I have only included the relevant parts:
but of course AddressIdentity is a string. Do I use ' ' marks with an & sign? Or can't I do this?? Maybe I need to use the codebehind anyway to see if the field exists before inserting it?
ive a DB in access with a single table and no primary key, actually i dont need a primary key but i can consider a date field plus another to make an index. however i want to add a counter field based on every change of date field, for instance ill have many records of 20/May and all must have the same id then when the date is different, the next group of records with that new date must show 2 etc.. is it a quick way to update my database?
I have a table with casenum as primary number and Identity column turned on. I know that the casenum will only auto-generated after a record is written into a table.
The front end to this table is a FormView on an AJAX webform.
Table is linked to the webform via LinqDataSource.
Now, on the webform, how can I display nextval before the record is actually written into a table?
I creating a real Estate web application. I have a form where the admin can type price for a specific property. The price will be insert into the SQL database.
Which is the best SQl data type to store for example : £150.000 and then retrieve it from the database. It has to be any type of SQL data that store number as I have a search on the website that compare values of numbers. It cannot be for example varchar othewise I will get an error.
I have a textbox which the user writes a word into. They then press a button to add that word to a list which is stored in the database.
What is the code to do add their word to the database? Do I need code on the main aspx file or only on the code behind?
What I tried doing up until this point is that once the button is pressed, in the codebehind the following happens:

I get errors telling me that the column name Program is invalid (I have a table named Program with one column named ProgramName)
I looked at a bunch of tutorials but nothing is straight forward and simple, it keeps confusing me. I need the simple step by step instruction to do this. I'm using a SQL database and coding in VB
i am trying to display a pop up message box on inserting the data into the database. The code i am using is as follows..
[Code]....
The problem is even on inserting the data and the data getting inserted into the database, the pop up mwindow does not get displayed. On debugging, it shows the value of i as 0.
I am working on an application and am attempting to use Linq with and ObjectDataSource but I only want to display/update 50% of the fields that are in the corresponding table. It appears to me that for this to work correctly, I need hidden fields on my form for all of the data fields from the table that the user cannot access. Is this the only way to do this? I have the following in my update method of my ODS:
[Code]....
The problem is, only the fields that appear on the form have data in them.
I am adding text fields to a page from the database. I set the .ID to match the record ID from the database. Of course becasue the text field is on the masterpage, when I grab the .ClientID, it is ctl00 contentMain$ctl00. what I don't get is where is my ID? If I set it to say AB how do I find the textbox by AB? I thought it should have AB in the ID somewhere. ID is nothing which I don't get either. I'm looping through the controls in a placeholder like this
For Each row In dtData.Rows() Dim c As Control For Each c In phTextRequired.Controls If c.UniqueID = row("CustomFieldID").ToString() Then
Again though what is in the row() is say AB but the id is way off from that.
I'm a beginner in programming and also to asp.net. I am trying to insert a row into an sql database using vb.net but I keep getting an error whenever I try to execute the code. I have read other post but I do not understand the solutions or how to place them within my code. Here is my stored procedure and vb.net code.
I wanted to know if it is possible to dynamically add columns to a table in the Database?I know how to create a table dynamically in the DB the code for it is given below, howver I do not know, how do I add columns to it dynamically.

This is the first time I have been working on databases and I am trying to insert data using an object datasource but no data is being inserted and no exception is thrown. I'm not sure where I am going to wrong. I am putting user data into session variables and inserting the session variables into the dataacess class layer and have a try and exception but nothing being thrown. Any help would be really appreciated because I don't know even where to start looking with this or how I can get the error to be thrown. Please see some of my code below to give an idea of what I am doing
Object Access Class public void InsertCarPolicyHolder(PolicyHolderClass ph, CarInsuranceOptions options) {
I have an ASP.NET project which has already some custom fields in it's web.config file. I've added in it three more fields and used them in my changes, and it's working great.
But where it needs to be used, there aren't these thre fields in the web.config (this was expected, I've just added by hand for tests and developing).
How do I check the existance of fields in web.config, and in case of not finding it, how do I add it permanently to the web.config ?
I need a form that displays three columns drawn directly from a database (no problems here) as well as two fields that require some complex calculations. Not only am I lost as to how to incorporate the calculations into the control, I don't know exactly how to write the calculations. I am working in Visual Web Developer 2008 with Vb.NET.
The first of the two fields should take the sum of all payments made by a given customer and divide it by a DailyMembershipRate, returning a DaysPaid variable. It should take this variable and a CustomerSince field for that particular customer and calculate a PaidThrough field.
The second of the two columns similarly requires the DaysPaid variable described above. It should subtract the CustomerSince field from the current date and return the value in days, giving a MembershipDays variable. Finally, it should subtract MembershipDays from the DaysPaid variable, again returning a value in days, and then multiply this by the DailyRate value for a Credit/Deficit field.
I realize this is a lot, but I haven't been able to find any documentation either online or in VWD or ASP.NET texts on this topic. I could really use some fellow user input.
I have a formview that is working fine for with the exception of the username is not inserting on a new record. The username is visible on login so I know that is working. I'm attaching my sql code as well as the code behind as I don't know what I'm missing.
I need to insert a Boolean value into an SQL Server datatable. I'm having a problem with what I'm trying. I don't see the option for a Boolean data type in SQL Server so I used Binary(1). Is this the right data type for storing Boolean in SQL Server?
