In the registration page of my project i want to check whether the enterd userid is available in database or not without sendig the whole page to server and i made userid as a primery key.
I have a SQL database that creates a record for every document uploaded by the user to the server. I want to check this table before a user uploads a document to ensure they don't upload a file with name that already exists.
I know how to make the connection and make the SqlCommand to query the table for an existing record. But I don't know how to check the record count from the sqlCommand I made.
Does that make sense?
Using myConnectionCheck As New SqlConnection(myConnectionStringCheck) Dim myCommandCheck As New SqlCommand() myCommandCheck.Connection = myConnectionCheck myCommandCheck.CommandText = "SELECT * FROM Req_Docs WHERE Doc_Name =" & DocName myConnectionCheck.Open() myCommandCheck.ExecuteNonQuery() End Using

I am developing web application using asp.net. Here i need to access two databases in which one is present on other server. I am able to connect to database present in same server but not with database present in other server.
I am using MS-access. I dont know the changes to be done and syntax for database connection.
On button click, I want to call a javascript code to check that If the entered BarCode Number in Textbox already exist in Database, then show an alert "Number already exist" else allow user to save and navigate to Default2.aspx
I can able to do the same checking on TextBox OnTextChanged event using c# code, as below:
protected void TextChanged(object sender, EventArgs e) { TextBox txtbarcode = fvIPRForm.FindControl("txtbarcodenumber") as TextBox; if (txtbarcode.Text.Length > 0 && txtbarcode.Text.Length < 11) { string error = "The Barcode Number " + txtbarcode.Text + " is invalid, the barcode length must be 11 character."; ScriptManager.RegisterStartupScript(this, typeof(string), "Successful", "alert('" + error + "');", true);
[Code] ....
Here, IPRRequest is the class/.dll file name and IsValidBarcodeTest is a function defined in the class file
But same checking I tried using the c# code on button's OnClick="btnSave_Click" event, but dont know why this event is not firing, I guess due to CommandArgument on button, but I am not sure.
textbox1.text="Delhi-manali" Then on button click event textbox2.text="Delhi" Textbox3.text="Manali" using vb.net If i type Delhi-Manali in textbox1 then on Button Click event textbox2.text="Delhi" & textbox3.text="Manali"
I'm using an access database that has an AutoNumber field as the primary key. After adding a record I'd like to retrieve the ID for the record that was just entered, however, I'm not able to figure out how to do this in ASP.NET using standard AccesDataSource and FormView functionality. My goal is to retrieve the ID so that I can then use it to add an additional record in a child / sub table.
I could do it strictly using vb.net and forget about using the InsertCommand for the AccessDataSource and it's built in functionality. However, that would require a complete rewrite of some other items, accomplish this using the standard AccesDataSource functionality.
Below is a sample of something I've tried to do using "Direction='Output'" on one of the ID field for one of Insert paramaters (source: http://www.4guysfromrolla.com/articles/050207-1.aspx). The plan was to then caputre that "output" using the my "_OnInserted" sub procedue. However, apparantly I'm not able to use this with AccessDataSource. Did some research and saw that I'd have to switch to SqlDataSource which I'd rather not do cause all other pages use AccessDataSource and I'm having problems defining my connection string with it.
Is there a way in ASP.NET to check if the browser where the page was requested is still open? If the browser is closed, a way to stop the request's rendering.
In my aspx page, I have a formview and a gridview. I am using the insert template of the form to insert an application number and applicant name both of which the user will enter.
I have a insert stored procedure that checks if that same number exist, it won't enter one, if not it will. ID of that table is autoincrement.
If a new number entered, it should show in the gridview as in my query I am asking to show the max ID. The applicatin number in the grid is a hyperlink which allows the user to go to a details page.
My problem: Whenever I click the save button in the formview, the grid becomes visible with the last created number. It is ok if the system allow to enter a new record. But if the number is a duplicate and the system does not enter a new number, still the grid shows with the last created number.
How can I implement what I want to do.
The stored procedure is:
ALTER PROCEDURE [dbo].[InsertNewChurchApp]nvarchar(6), @AddBy @Applicant nvarchar(80), @PK_ApplNo nvarchar(19),
