check the credentials and mail server.
you use smtp service?

some like this:
public static void sendMail(string _to, string _subject, string _body)
{
MailMessage correo = new MailMessage();
correo.From = new MailAddress(_emailFrom);
correo.To.Add(_to);
correo.Subject = _subject;
correo.Body = _body;
correo.IsBodyHtml = false;
correo.Priority = MailPriority.Normal;

SmtpClient smtp = new SmtpClient();
smtp.Host = _server;

smtp.Credentials = new NetworkCredential(_user, _pwd);

try
{
smtp.Send(correo);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "TestOfApplication",
MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}

regards

Hi,

Im have addressed some of the problems such as the attachEvent only supported in IE, but im having problems loading the image as the user draws i.e. it only updates the image once the mousemove event has finished.

use the HTML name attributre as place holder for other value.

<br />
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)<br />
    {<br />
        CheckBox chk = new CheckBox();<br />
        // use name html attribute as your ID placeholder<br />
        chk.Attributes.Add("name", e.Row.Cells[100].Text); //e.Row.Cells[100].Text is my column id <br />
        e.Row.Cells[0].Controls.Add(chk);<br />
<br />
    }<br />
<br />
    protected void Button1_Click(object sender, EventArgs e)<br />
    {<br />
        Int16 count = (Int16)GridView1.Rows.Count;<br />
        for (Int16 i = 1; i < count; i++)<br />
        {<br />
            CheckBox chk = (CheckBox)GridView1.Rows[i].Cells[0].Controls[1];<br />
            //get the value of attribute name.<br />
            string id = CheckBox3.Attributes["name"];<br />
        }<br />
    }<br />

CompositeControl with dynamic controls

cgreathouse26-May-09 5:40

cgreathouse

26-May-09 5:40

I have a class that inherits from CompositeControl that dynamically creates controls at runtime (typically 2-5 DropDownList controls). All of the control creation is happening in CreateChildControls().

When a page using that control first loads everything is correct. However, after the selected index is not being remembered. It doesn't matter what is selected in the DropDownList controls, SeletedItem or SelectedValue is always the first item in the control.

I then found some posting that said AutoPostBack needs to be set on the DropDownList Controls and that a check for IsPostBack needed to be put in CreateChildControls(). I did that but when a new item in any of the DropDownList controls was selected, all of the DropDownList controls were empty.

I then saw something that said for the ViewState to be preserved, the DropDownList control must first be added (i.e. Controls.Add()) and then load the control. That didn't help either.

Has anyone done anything like this before? Any guidance and how to get this thing to work?

Thanks!

i have dropdownlist1,dropdownlist2,textbox1,button1,button2,dropdownlist3

here i am selecting an item from each dropdownlist, perform concatinating and i showed in textbox fine.

but when i want to enlarge concatination means the selected item text will be overridden on the previous selecteditem text
i want to prevent this..

finally i want the TextBox2 output as follows;

exa:
(ddl1) (ddl2) (txt1) (btn1) (ddl) (ddl2) (txt1) (ddl3)
Month_no = 5 and Quarter_no = 3 group by(abc)

means
month_no = 5 and quater_no = 3 group by(abc)

how to get this one.........

help me out...

textbox2.Text=ddl.selecteditem.text+ddl2.selecteditem.text+-----------

use the string format

Month_no = string.Format("{0} {1} {2} {3} {4} {5} {6} ({7})", (ddl1),(ddl2),(txt1) (btn1),(ddl),(ddl2),(txt1),(ddl3));

Web Crystal Report from NT Current Event Log

Yakimo26-May-09 4:31

26-May-09 4:31

Hi
I have a trouble displaying Web Crystal Report from NT Current Event Log .
Using Crystal Reports 2008 I have created RPT file, with a data source NT Current Event Log, showing Security log from a network server from my LAN. The report is running fine from the designer, and also it runs fine from Visual Studio 2008 (C#) IDE
But if I try to deploy and run it from the web server, it fails.

I think that the user IUSR_MYServer that is running the web apps doesn't have right to open the remote EventLog, that's why I would like to supply another user/password on the connection

Is there any way to supply user name/password to the Crystal Reports web report, reporting from a remote server EventLog (Crystal Reports 2008)

Can I specify something similar to ADO connectionString (from code, dynamically), so I can specify the user/password

In my case I use VS 2008 (aspx 3.5, C#), CrystalReports 2008

Has somebody experienced this problem and what can be the solution?

regards,
Yakimo

Got an error when i deployed not a valid virtual path. though i have added permissions to image folder on the server.
Iam using a function that returns save location and uploads the image. this is the code iam using:

Private Function Uploaded() As String
       Dim filePath As String = AppSettings("~\Images")
       Dim SaveLocation As String = String.Empty
       If Not txtImgURL.Text.Length = 0 And Left(txtImgURL.Text, filePath.Length) <> filePath Then
           Dim fileName As String = System.IO.Path.GetFileNameWithoutExtension(txtImgURL.Text).ToLower()
           Dim fileExtention As String = System.IO.Path.GetExtension(txtImgURL.Text).ToLower()
           SaveLocation = System.IO.Path.Combine(filePath, fileName & fileExtention)
           Dim physicalLocation As String = Server.MapPath(SaveLocation)

           If File.Exists(physicalLocation) = True Then
               Dim sequencer As Integer = 1
               SaveLocation = System.IO.Path.Combine(filePath, fileName & "_" & sequencer.ToString & fileExtention)
               physicalLocation = Server.MapPath(SaveLocation)

               Try
                   My.Computer.FileSystem.CopyFile(txtImgURL.Text, physicalLocation)
               Catch
                   My.Computer.FileSystem.CopyFile(Server.MapPath(txtImgURL.Text), physicalLocation)
               End Try
           Else

           End If
       End If
