Hello,
I use the asp:login control, but the task now is to integrate facebook. Facebook gives me an userid. With that userid, I have to check if that user already exists and log him in if it does.
This would mean I have to call some method that sets current user. But on login button I have LoginControl_LoggedIn that I would need to execute.On login button I have CommandName="Login". How do I call login from code?
Thank you very much.

hi,
i am displaying a messagebox server side. For that i have developed a class which is called from an aspx page which inherits masterpage. the master page includes asp:updatepanel control and updateprogress control. due to this i cant use httpconetxt.current.response.write to display the message box.
Following is the aspx code:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class Presentation_Admin_Menu_MenuGroup_MenuGroupDetail : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
MsgPopUp.Show(Page, "sandeep with me");
}
}
THIS IS THE CLASS CODE FOR DISPLAYING THE MESSAGEBOX
====================================================
public static void Show_Panel(Page sender, string Message)
{
try
{
UpdatePanel sender1 = (UpdatePanel)sender.Master.FindControl("UpdPanel");
ScriptManager.RegisterStartupScript(sender1, typeof(UpdatePanel), "ABC", "alert('"+Message+"');", true);
//if (!(handlerPages.Contains(HttpContext.Current.Handler)))
//{
// Page currentPage = (Page)HttpContext.Current.Handler;
// if (!((currentPage == null)))
// {
// Queue messageQueue = new Queue();
// messageQueue.Enqueue(Message);
// handlerPages.Add(HttpContext.Current.Handler, messageQueue);
// currentPage.Unload += new EventHandler(CurrentPageUnload_withupdpanel);
// }
//}
//else
//{
// Queue queue = ((Queue)(handlerPages[HttpContext.Current.Handler]));
// queue.Enqueue(Message);
//}
}
catch (Exception ex)
{
throw ex;
}
}
private static void CurrentPageUnload_withupdpanel(object sender, EventArgs e)
{
try
{
Queue queue = ((Queue)(handlerPages[HttpContext.Current.Handler]));
if (queue != null)
{
StringBuilder builder = new StringBuilder();
int iMsgCount = queue.Count;
builder.Append("<script language='javascript'>");
string sMsg;
while ((iMsgCount > 0))
{
iMsgCount = iMsgCount - 1;
sMsg = System.Convert.ToString(queue.Dequeue());
sMsg = sMsg.Replace("\"", "'");
builder.Append("alert( \"" + sMsg + "\" );");
}
builder.Append("</script>");
handlerPages.Remove(HttpContext.Current.Handler);
//HttpContext.Current.Response.Write(builder.ToString());
Page currentPage = (Page)sender;
UpdatePanel sender1 = (UpdatePanel)currentPage.Master.FindControl("UpdPanel");
ScriptManager.RegisterStartupScript(sender1, typeof(UpdatePanel), "ABC", "alert('Hi, I did it!');", true);
//currentPage.RegisterStartupScript("alert", builder.ToString());
//if (!script.IsClientScriptBlockRegistered(script.GetType(), "Alert"))
//{
// script.RegisterClientScriptBlock(script.GetType(), "Alert", "alert('record inserted');", false);
//}
}
}
catch (Exception ex)
{
throw ex;
}
}
Instead of httpcontext.response.write i use
UpdatePanel sender1 = (UpdatePanel)currentPage.Master.FindControl("UpdPanel");
ScriptManager.RegisterStartupScript(sender1, typeof(UpdatePanel), "ABC", "alert('Hi, I did it!');", true);
in the above class code. But the message box doest not get displayed.
Thanks.

Hi,
Try this, i got the same issue
ScriptManager.RegisterClientScriptBlock(sender1, typeof(UpdatePanel), ("dialogJavascript" + this.ID), "alert(\"Registered\");", True)

hi jamii,
this.ID in you reply means exactly which id.
i am actually displaying the messagebox through class.
in my aspx page i am using the object of the class and passing the message to the method which in turn displays the messagebox

You can always check the key for the script with IsClientSideScriptRegistered to ensure you don't register it multiple times.

Hi Huys
I am working on a web application in which i create a mailing system,
which is internal mailing system for that application.
now I want, If any user sending mail from out side mailserver like gmail or yahoo which should be received in my Application Inbox
Is it possible if yes then how, Please help me
Thanks in Advance

Receiving mail is a whole different beast than sending mail.
If you're in a corporate environment, you should ask the mail administrator which are the recommended ways of doing this.
Otherwise, the following article[^]
implements a simple pop3 server with eventing. You could do something similar.
The point is that internet mail is distributed through smtp servers. In order to receive mail from the internet, you need a public domain name, MX records in you domain DNS, and a fixed IP address.
If you can't do that, you'll have to register a mail address with a free mail provider (or with your ISP).
You can then access that mail through the POP3 protocol(all providers), the IMAP protocol (some providers), or something else (for example MAPI)
Your best bet is pop3, after you've registered a mail address. I've found a pop3 class library at Codeplex[^], you may wanto check it out

Please how do i get java script to work on IE 7. the code works fine in Firefox, it the Epoch calendar function that i am using in my project.
thanks.

Hi,
your javascript code should works fine on IE7 but there is some compatibility issues that you have to take into your consideration, please post here the code that is not working so we can suggest a solution
anyway check this link for more information about javascript compatibility issues

Hi Arindam,
why you need to detect the browser type/version, i think the best practice is to have a javascript code that works(compatible) with all type of browsers .
Regards,
Jamil

Hi Jamil,
Yes, you are correct, the best practice is that one should write a code which is independednt of type of browser. Unfortunately not all javascript is supported by all browser's javascript processing engine. Thats why we need to detect browser type and write code.
As in the problem statement says that the person is having a piece of code which is wokring in Mozila and not in IE 7.0, that prompted me to suggest the same.
But rule of thumb is definitely as you have mentioned. 
Thanks,
Arindam D Tewary

|

oh, i see i got your idea.
but from my point of view i would prefer to write a code that is compatible with the main browsers (Firefox, IE and Chrome)
Regards,
Jamil
|
|
|
|
|
I agree to you Arindam. There are a lot javascript code that does not run smoothly on all main browsers. So sometime we have to go for detecting the browser and take the steps accordingly.
Everytime we can not get all js code that run all the browser, might be one has to pick another approach or rely very less on javascript, and use server side code as much as possible but this is not good for performance point of view.
Hope the coming new browser follow the same standards and create less pain for us

this is the segment of code;
<asp:tablecell>
var popup1;
window.onload = function() {
popup1 = new Epoch('popup1','popup',document.getElementById('txtdateofbirth'),false);
};
thanks again.

Hi,
i see that you are using the Epoch Popup calendar, it is really nice
which section of the code is not working? because this Popup is compatible with the main browsers .
by the way why are you using onfocus="popup1.setTarget(this)"?
Regards,
Jamil
|
|
|
|
|
oh i got the reason:
It lets you assign a single instance of Epoch to an unlimited number of <INPUT> boxes—all you need to do is add an onFocus() event handler to the box. This saves both memory and reduces your page's load time.

Jamil

hi, iam using asp.net with c#
i have table images
shop nvarchar(50),
imgc image
imgo image
iam saving images in a database but while retreving it is showing blank images. i want to display as thumb nail images ,
can you correct my code which helps me
saving code
protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile && FileUpload2.HasFile)
{
img1.ImageUrl = imgc.ImageUrl;
img2.ImageUrl = imgo.ImageUrl;
FileUpload1.SaveAs(MapPath("~/images/" + FileUpload1.FileName));
imgc.ImageUrl = "~/images/" + FileUpload1.FileName;
FileUpload2.SaveAs(MapPath("~/images/" + FileUpload2.FileName));
imgo.ImageUrl = "~/images/" + FileUpload2.FileName;
con.Open();
SqlCommand cmd = new SqlCommand("Addimgproc",con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@Shop","Alsafa");
FileInfo imageinfo = new FileInfo(FileUpload1.PostedFile.FileName.Trim());
byte[] content = new byte[imageinfo.Length];
FileStream imagestream = imageinfo.OpenRead();
imagestream.Read(content,0,content.Length);
imagestream.Close();
FileInfo imageinfo1 = new FileInfo(FileUpload2.PostedFile.FileName.Trim());
byte[] content1 = new byte[imageinfo1.Length];
FileStream imagestream1 = imageinfo1.OpenRead();
imagestream1.Read(content1, 0, content1.Length);
imagestream1.Close();
cmd.Parameters.AddWithValue("@imgc", content);
cmd.Parameters.AddWithValue("@imgo",content1);
cmd.ExecuteNonQuery();
con.Close();
}
}
retreiving code
================
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
SqlCommand cmd = new SqlCommand("select imgc,imgo from images where Shop='Alsafa'",con);<br />
<br />
con.Open();<br />
<br />
SqlDataReader dr = cmd.ExecuteReader();<br />
if (dr.HasRows)<br />
{<br />
<br />
while (dr.Read())<br />
<br />
{<br />
Image1.ImageUrl = dr["imgc"].ToString();<br />
Image2.ImageUrl = dr["imgo"].ToString();<br />
<br />
}<br />
dr.Close();<br />
<br />
}<br />
con.Close();<br />
<br />
}

Hi,
Can you please mention what problem you have with your code. It would be good if you can say whether you get any error/exception or what is not happening (that was expected !!!). Please let us know which line you might be suspecting something problem!!!
Unless you mention those ponts, it will not be possible for people to go through your code or compile your code and to see what is happening!!.
Thanks,
Arindam D Tewary

you are storing images in binary in sql server...n you r directly use tostring() function on it..!!!
bool flgImage = false;
byte[] buffer = new byte[0];
buffer = (byte[])SQLHelper.ExecuteScalar("SELECT imgImage FROM dbo.MeasurementImages WHERE intImageID=id");
context.Response.ClearHeaders();
context.Response.Expires = 0;
context.Response.Cache.SetNoServerCaching();
context.Response.Cache.SetMaxAge(TimeSpan.Zero);
context.Response.ContentType = "image/gif";
context.Response.Cache.SetCacheability(HttpCacheability.Public);
context.Response.BufferOutput = false;
context.Response.OutputStream.Write(buffer, 0, buffer.Length);
context.Response.Flush();
context.Response.End();
Make image handler file for retriving images from database. this is a better way.
!- F - R - I - E - N - D - S -!

In a datalist control i have a imagebutton with command name="Cancel" but when i click that
in the datalist i am getting the following error
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
