Re: Checkbox column in a grid view...

29-Aug-07 20:02

Put one more label in this checkbox column. the DataField of this label should be mapped to the actual field from database.
In Item_DataBound() event of GridView, you can check whether the value is 0 or 1. then, find the checked box control and check or uncheck based on the value..

Eg: Item_DataBound Event

Label lbl = (Label)e.FindControl("lblValue");<br />
CheckedBox chk = (CheckedBox)e.FindControl("chkCheckedBox");<br />
chk = (lbl.Text == "1") ?? true:false;<br />

Given this is the C# forum, don't you think it would look terrible if all threads had the subject 'C#'?

SqlDataReader reader = sqlCommand.ExecuteReader();<br />
GridView1.DataSource = reader;<br />

Is there a way to have StreamReader start reading a file from the end? I know there is no method, but is there some type of way using the stream class?
I have some large files where the data that needs to be gathered is at the very end and looking to cut down on the processing time.
BTW using 1.1

Threaded Form

I am having trouble with closing a form created in a seperate thread. This is what I am trying to accomplish: I have a program that runs in the taskbar. When a user double-clicks a key, a form is created in a new thread and is shown on top of all other forms. When the user clicks anywhere outside the form, the thread will close, but the program will continue to run in the background. This is similar to the Google Desktop functionality. The code works the first time the form is created in a new thread, but if the form has been closed once, you have to click on the form to make it active and then click outside of it before it will close. I have tried using the Deactivate and LostFocus events, but they both only work the first time the form is shown. Any suggestions would be greatful. I have included a snippet of code below.

<br />
public class MyClass {<br />
    private Thread _thread;<br />
    private FMain _fmain;<br />
    private UserActivityHook _keyhook;<br />
<br />
    public MyClass() {<br />
        _keyhook = new UserActivityHook(false, true);<br />
        _keyhook += new KeyEventHandler(KeyDoubleClick);<br />
    }<br />
<br />
    private void KeyDoubleClick(object sender, KeyEventArgs e) {<br />
        if (e.KeyValue == 163) {<br />
            _thread = new Thread(new ThreadStart(OpenForm));<br />
            _thread.Start();<br />
        }<br />
    }<br />
<br />
    private void OpenForm() {<br />
        _fmain = new FMain();<br />
        _fmain.Deactivate += new EventHandler(form_Close);<br />
        _fmain.LostFocus += new EventHandler(form_Close);<br />
        _fmain.ShowDialog();<br />
    }<br />
<br />
    private void form_Close(object sender, EventArgs e) {<br />
        _thread.Abort();<br />
    }<br />
}<br />

I don't think you need to close the form. Why don't you just hide the form when it is deactivated and show the form when it is activated?

Thank you for the suggestion. My problem though is trying to get the form to Hide/Close once the user clicks/types outside the form. Is there an event fired when this happens that I am not aware of or do I need to use a global hook? If I was to use a hook, how do I know that the source of the hook was not within the form?

Michael Sync29-Aug-07 18:05

29-Aug-07 18:05

What about Deactivate event of form?

private void Form1_Deactivate(object sender, EventArgs e)<br />
        {<br />
            this.Hide (); <br />
        }

I think that this "Deactivate" event is good enough. I dont think you need to use Window Hooking.

you might be able to use .ActiveForm.Close() if you call it from the same thread which generated(showed) the form, else you'll get a "cross-thread exception"

Is this form some type of information "pop-up" ? if so you could just call .Show() and then set a timer to call the .ActiveFrom.Close() on it. Also keep your current if you click on it and then click away it closes.
This would be a better user experience, as they don't have to keep clicking away close the dialog.

another problem is that you are calling abort() to your thread and not allowing it to exit cleanly

All threads should include a method to stop their execution loop, .abort() is to throw an exception on a soft-locked thread. A situation where you know that it should have quit already but it is stuck in some loop.

The exception doesn't allow the thread to finish its task. Think what will happen if a thread was in the middle of saving some file that was only 1/2 written when it was aborted.

The below quick function will back up a database

public void BackupDataBase(string databaseName,string Path)
{

string backUpQuery = "USE MASTER"+
"EXEC sp_addumpdevice 'disk', 'MyTestDatabase',"+ path+databaseName+".bak"+
"BACKUP DATABASE "+ databaseName +"TO MyTestDatabase";

SqlConnection con = new SqlConenction(connectionString);
con.Open();

SqlCommand cmd=new SqlCommand(backUpQuery,con);
cmd.ExecuteNonQuery();

}

Please modify the same as required.

Insert statment for multiple tables

falles0129-Aug-07 15:49

29-Aug-07 15:49

Could someone possibly please show me an example, even if it's a parametized query how I can insert into multiple tables.
I have a new employees form with name, role, manager, division, skills, applications. The employee table only has the employeeID primary key, firstname, lastname and then all the foreign key id's for the other tables. The other tables have the other info like description etc.

If I'm creating a new employee, I obviously want them all to update based on the same employee and then the ID's to automatically insert based on the pf fk relationship.

I have searched on google but I can only find examples where you insert one at a time, which works but its not related to the employeei have entered.

Thank you so much

string sql = "INSERT INTO employees(Firstname,Lastname) Values ('" + FirsttextBox.Text.ToString() + "' , '" + LasttextBox.Text.ToString() + "' and Insert into Role (Role) Values ('" + RolecomboBox1.Text.ToString() + "')Insert into Manager (MFirstname) Values ('" + ManagercomboBox1.Text.ToString() + "') Insert into Division (DivisionName) Values ('" + DivisioncomboBox1.Text.ToString() + "')";

A trigger may not always be the best solution. You have to look at performance and other aspects also.

Your best solution would be to create a stored procedure and call it within your code "ExecuteNonQuery." The stored procedure will do all the work of inserting the records into the proper tables. As far as I know, there is not a way, with SQL Server, to insert into multiple tables with one INSERT statement. This also gives you the ability to do error checking on the back-end.
