2nd INSERT INTO Statement In A Button Click Event

Mar 6, 2006

Hi everyone.I am trying to write 2 INSERT INTO statements into a Button click event. Both statements go to the same database but differnet tables. The first statement works fine but the 2nd causes an error with the Try, Catch, Finally statement. When I remove the ExecuteNonQuery from the 2nd statement, the 2nd INSERT INTO statement fails to work. Any help would be brilliant. Thanks!

Datsource Delete Event Fires - Why???

Mar 17, 2008

I have "sqlGetReservationMembers" datasource in my ascx code and another datasource in 'KillReservation'. As you can see "sqlGetReservationMembers" uses a SELECT command only. I have verified this several times. The 3rd block below is the only place in code-behind where "sqlGetReservationMembers" is referenced. When the "KillReservation" fires I get an error stating "Deleting is not supported by data source 'sqlGetReservationMembers' unless DeleteCommand is specified". I'm confused because I can't see where the 'sqlGetReservationMembers' delete event is being fired. I have removed the datasource and recreated it but the problems returns. What am I missing?
Thanks

SqlDependency OnChange Event Fires Repeatedly

Mar 27, 2008

I am using the SqlDependency to notify me of data changes in a table. However, as soon as I start it, the OnChange event fires over and over even though no data has changed.

Essentially All I want to do is be notified when records are inserted into a table. I am able to get another example to work using a Service Broker Queue and a sql query of WAITFOR ( RECEIVE CONVERT(int, message_body) AS msg FROM QueueMailReceiveQueue ) However I would prefer not to use a queue for once my messages have been read they are taken off the queue and I would rather control that manually.

Any help with getting SqlDependency to notify my app when records are added and not over and over when the data has changed would be great.

Here is my code:




Code Snippet
public partial class Form1 : Form {


public static event OnChangeEventHandler OnChange;
string _strConnString = "Data Source=localhost;Integrated Security=SSPI;Initial Catalog=email_queue;Pooling=False;";
string _strSql = "SELECT email_id from email where isprocessed = 0";
private DataSet dataToWatch = null;
private SqlConnection connection = null;
private SqlCommand command = null;
SqlDependency dependency = null;
SqlDataReader sdr = null;


public Form1() {


InitializeComponent();
}

private void button1_Click(object sender, EventArgs e) {

SqlDependency.Stop(_strConnString);
SqlDependency.Start(_strConnString);
if (connection == null) {

connection = new SqlConnection(_strConnString);
connection.Open();
}
if (command == null) {

command = new SqlCommand(_strSql, connection);
}
if (dataToWatch == null) {

dataToWatch = new DataSet();
}
GetData();
}

private void GetData() {

dataToWatch.Clear();
command.Notification = null;
dependency = new SqlDependency(command);
dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);
command.CommandTimeout = 400;
using (SqlDataAdapter adapter = new SqlDataAdapter(command)) {

adapter.Fill(dataToWatch, "email");
}
}

private void dependency_OnChange(object sender, SqlNotificationEventArgs e) {

ISynchronizeInvoke i = (ISynchronizeInvoke)this;
if (i.InvokeRequired) {

OnChangeEventHandler tempDelegate = new OnChangeEventHandler(dependency_OnChange);
object[] args = { sender, e };
i.BeginInvoke(tempDelegate, args);
return;
}
dependency = (SqlDependency)sender;
dependency.OnChange -= dependency_OnChange;
this.Text = DateTime.Now.ToString();
GetData();
}

private void Form1_FormClosed(object sender, FormClosedEventArgs e) {

SqlDependency.Stop(_strConnString);
if (connection != null) {

connection.Close();
}
}
}

SQL && C# Help On A Button Click!!!

Mar 7, 2008

Hey Guys,
I'm not sure if anyone can help me with this but I am trying to achieve the following:
I have a row (In this case it is information on a fix) and on a button click I am trying to get it to "archive" it.  At the moment I have it so that it it takes the current information and adds it to the archive table adding an archive date.  The thing that I am struggling with is incrementing the version number. So, I need it to (in these steps I think) - Look for existance of the other entires of that ID, look for the version number that is related to the newest date of those knowledgeIDs and then add 1 to it.  If that knowledgeID doesnt exist then add it as one.
My current code is below:
Thanks in Advance =)
C# Codeprotected void Page_Load(object sender, EventArgs e)
{UserName = (string)Session["UserName"];
Label4.Text = UserName + " Is Current Logged In";UserType = (string)Session["UserType"];if ((Session["UserName"] != null) & (UserType == "Helpdesk"))
{Response.Redirect("Accessrights.aspx");
}else if (Session["UserName"] == null)
{Response.Redirect("Login.aspx");
}
FixName = "default";Description = "default";File = "default";
ADate = myCalendar.TodaysDate.ToShortDateString();
AddDate = Convert.ToDateTime(ADate);myConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=C:\inetpub\wwwroot\HOF\App_Data\HOF.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True;";
}protected void Button1_Click(object sender, EventArgs e)
{SqlConnection myConnection = new SqlConnection(myConnectionString);
try
{
FixName = TextBox1.Text;
 SqlCommand myCommand = new SqlCommand("select * from Knowledge WHERE FixName like '%" + FixName + "%'", myConnection);
myConnection.Open();SqlDataReader myReader = myCommand.ExecuteReader();if (myReader.HasRows)
{while (myReader.Read())
{
TextBox1.Text = myReader["FixName"].ToString();TextBox2.Text = myReader["Description"].ToString();
File = myReader["Location"].ToString();if (File != null)
{
TextBox3.Text = File;
}
else
{TextBox3.Text = "There is no script avaliable";
}KnowledgeID = myReader["KnowledgeID"].ToString();Add = myReader["DateAdded"].ToString();
}
myConnection.Close();
}
else
{TextBox1.Text = FixName + "Does not Exist. Please try again.";
}
}catch (Exception ex)
{
myConnection.Close();
}
try
Description = TextBox2.Text;File = Convert.ToString(FileUpload1.FileName);if (CheckBox1.Checked == true)
{SAPPS = "True";
}
else
{SAPPS = "False";
}
{SqlCommand mycommand2 = new SqlCommand("INSERT INTO Knowledge (FixName, Description, Location, DateAdded, DateArchived, Version, KnowledgeID) SET ('" + FixName + "','" + Description + "','" + File + "','" + Add + "','"+AddDate+"','" + SAPPS + "','"+I NEED A VALUE HERE+"','"+KnowledgeID+"')", myConnection);SqlDataAdapter myDataAdapter = new SqlDataAdapter(mycommand2);
sa = mycommand.ExecuteNonQuery();
myConnection.Close();

Executing SQL With A Button Click.

Dec 25, 2007

I feel like it must be easy and I'm missing something.  Maybe I'm going the wrong way about it too.  Basically I've written an append query that needs parameters, but I have no idea how to actually execute it.  I'm coming from building apps in MS Access where all of this is really easy.  I'm really enjoying learning some things, and did my first MS SQL trigger event tonight, which worked great.  I though using a trigger may be an option here, but I need to control the "when" of this append a little more carefully and can't rely on an automated event. I can manually execute the query and it works, but have a button I could press on a form, with the queries on that form would be ideal.  I'm basically moving partial data from one table to another. Any help?  Again, this seems like it "should" be easy, but I'm not finding info on it.  Please talk slowly, as again, I'm coming from Access.

How To Execute A Selectcommand On Button Click?

Jan 9, 2007

Hello friends
Can anyone tell me the means by which I can populate a label or a datagrid by executing a selectcommand statement on the form of my webpage. And what is the best way to retrieve data from a SQL datasource, is it by using separate sqldatasources for each different parts of a page that requires different data from different tables in the same database or by using a tableadapter to retrieve the data for the best performance?
Thanks for replying for my previous questions. It was helpful and great in my program implementation.
Thank you

Running An SSIS Package After A Webpage Button Click

Jun 12, 2007

Hi all!
I'm a newbie when it comes to SSIS and web development (I'm currently in school for Mechanical Engineering). I'm trying to develop a website in which I can upload an excel file and have the contents written to a SQL database. I have been successful in creating a package in which I point to an excel file and it writes the contents to the desired database. With this, I was hoping that I can modify my website to take the file which is being uploaded, change the name, and then have the SSIS package run, in which it will look for the named file in a certain directory and upload the contents to the SQL server.

Ideally this would be the order of events:

User selects and uploads a file to the server (button click)
Server renames it and places it in a certain directory
SSIS package runs and extracts the data to SQL database


Thanks all!

System Restarts On Click Of The Print Button While Viewing Reports In The Browser

Apr 17, 2007

We are using Reporting Services 2000.

The print button that is present in the browser is working just fine for some users.



But some users are complaining that on clicking the print button their system restarts.



Some other users are also getting the error "An error occurred during printing. (0x80004005)"

However on closing the browser and opening the report in it again this issue is resolved.



So, the main concern is "Restart of the machine on click of the PRINT icon in reports viewed in some application browser."



Please help!!

I've got a SQL Reporting Server 2000 SP2 report that takes 3 parameters. FromDT, ToDT, and LocationCD. The first two parameters are free form text fields that expect a date. The last one is a drop down box. For some reason, when I'm viewing the report through the standard reports folder on the report server I have to click the "View Report" button two times to get the report to render. Clicking it just once, doesn't seem to do anything. The report is a line graph.

There are default values in the FromDT and ToDT parameter fields.

Anyone have any ideas what would be causing the need for the second click?

Toggle Event, Jumps To Top Of Page

Feb 19, 2008

I have a report with 30 to 100 line. I also have groups collapsed. When I expand a group, I get a postback and a 'toggle event', which causes the report to jump to the top. I would like to stay where I expanded the group. Any suggestion?

Trigger Fires In One Db And Populate Another Db

Apr 12, 2007

hi,

I want a trigger in db aaa to fire when table a_aaa is updated in server a and table b_bbb in db bbb in server b to be populated with data. I know how to write a trigger if fired and the result stays in one server with one db. But I don't know how to do it if between two servers and two db.

a
win server 2003 standard Edition
sql Server 2000
db:aaa
table: a_aaa
column:a_aaa_a

b
win server 2003 standard Edition
sql Server 2000
db:bbb
table:b_bbb
column: b_bbb_b

It's not working because the symtax is incorrect and because I am not sure how to do it between two servers. If it is not correct, where am I wrong? Where should each line be located?? et cetera......
Can anyone help?

Thanks in advance.
