Application_Error not working in production server - asp.net

Application_Error was not firing on production server. but its working in our local server and other amazon server. in our local server have windows7 OS and IIS (7.5)version, but the production server have Windows8 and IIS (8+) version. any one have any idea.
void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
Exception ex = Server.GetLastError().GetBaseException();
string cls = ex.TargetSite.DeclaringType.Name;
string mtd = ex.TargetSite.Name;
string ErrorMessage = ex.Message;
string page = Request.Path;
string url = Request.PhysicalPath;
string StackTrace = "";
string inputdata = "";
if (ErrorMessage != "File does not exist.")
{
StackTrace = ex.StackTrace;
foreach (string i in Session.Contents)
{
if (Session[i] != null)
{
if (inputdata != "")
{
inputdata = inputdata + " , [" + i + "] = " + Session[i].ToString();
}
else
{
inputdata = "[" + i + "] = " + Session[i].ToString();
}
}
}
string flg = objBus.insertException(page, "", ErrorMessage, StackTrace, "", url, Session["UserID"].ToString(), inputdata,"");
//string flg = "0";
//Response.Redirect("~/ErrorPage.aspx?errorId=" + flg, false);
Server.Transfer("~/ErrorPage.aspx?errorId=" + flg, false);
}
}

When you publish try to enable "Precompile during publish", this should include PrecompiledApp.config in publish folder

Attachment structure is:
In attachment we are sending bin files of objects and these objects further extracted and saved in database.
Problem:
Some times we are receiving large files, so while extracting service hang and stop processing in between. Could you provide me some suggestions and ideas to overcome this issue.
Please let me know if you need more information, I will try my best to provide.
Thanks in advance.
You are using DataTables.
A DataTable is an in-memory copy of relational data.
So all the data you are going to save have to fit into memory.
If you have a lot of records, big records or both this will not do.
I suggest to:
decompress the file inside a temp folder on local file system
insert into the database one file at a time using a SqlCommand
Use parameters in your INSERT command (ie insert into mytable (col1, col2) values (#col1, # col2))

I have an error when I delete an image from folder

`protected void LinkButtondelete_Command(object sender, CommandEventArgs e)
{
int macv = 0;
if (Page.Request.Params["id"] != null)
macv = int.Parse(Page.Request.Params["id"]);
if (macv != 0)
{
string sqldelete = "delete from T_CongViec_Attach where MaAttachFile=" + e.CommandArgument.ToString() + " and MaCV=" + macv;
ulti.ExecSqlDataSet(sqldelete);
}
else
{
string sqldelete = "delete from T_Attachfile_CV where id=" + e.CommandArgument.ToString();
ulti.ExecSqlDataSet(sqldelete);
}
foreach(DataListItem item in DataListAttachfile.Items)
{
string vitualpath = System.Configuration.ConfigurationManager.AppSettings["UploadPath"].ToString() + DateTime.Now.Year.ToString() + "/" + DateTime.Now.Month.ToString() + "/" + DateTime.Now.Day.ToString() + "/" + att.Duongdanfile;
string savepath = HttpContext.Current.Server.MapPath("/" + vitualpath);
File.Delete(MapPath(vitualpath));
}
show_data(macv);
lblMessage.Text = "Delete successffully!";
}`
and this is the error:Access to the path 'D:\cms_vietnamnews_final\ToasoanTTXVN\Upload\Images\2018\9\19\' is denied.
It might be the App pool, and to fix it you need to login to Plesk and navigate to file [file manager] then select the folder you need and change the permissions by giving the [Application pool group ] the required permission.

asp.net upload control is not working in ipad

The asp.net upload control is uploading the file for first time in Ipad but not after that and not even showing any error
The code is as below
protected void UploadThisFile(FileUpload upload)

try
{
string folderpath = ConfigurationManager.AppSettings["BTCommDynamic"].ToString() + ConfigurationManager.AppSettings["Attachments"].ToString();
Guid fileguid = Guid.NewGuid();
string filename = fileguid + upload.FileName;

upload.SaveAs(theFileName);
drFileRow["FilePath"] = theFileName1;
double Filesize = (upload.FileContent.Length);
if (Filesize > 1024)
{
drFileRow["FileSize"] = (upload.FileContent.Length / 1024).ToString() + " KB";

else

string message = Utility.GetExceptionMessage(ex.GetType().ToString(), ex.Message);

}
}
Do you use firebug? There might be an error on a client side that prevents the work of your functionality.
Do you have any logic on your client side? Some kinda jquery/ajax calls?

How to make a STS using Gmail OAuth

We want to make an STS that outsources the authentication to google.
Following the steps stated in https://developers.google.com/accounts/docs/OAuth2Login?hl=es-ES we have the following code in the Login.aspx generated by the sts web site template in vs2010:
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["code"] != null)
{
//I'm coming from google, already authenticated
FormsAuthentication.SetAuthCookie(GetUserName(Request.QueryString["code"]), false);
Response.Redirect("default.aspx");
}
else
{
//I want to authenticate
Response.Redirect(
"https://accounts.google.com/o/oauth2/auth?" +
"response_type=code&" +
"client_id=988046895016.apps.googleusercontent.com&" +
"redirect_uri=" + HttpUtility.UrlEncode("https://localhost/GmailSTS/login.aspx") + "&" +
"scope=" + HttpUtility.UrlEncode("https://www.googleapis.com/auth/userinfo.email")
);
}
}
But I get an error beacuse wa is not specified in the QueryString, debugging the samples and the generated template I saw that wa,wtrealm,wctx and wct are the parameters needed so I used the state parameter so they roundtrip and get them back:
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["code"] != null)
{
//I'm coming from google, already authenticated
FormsAuthentication.SetAuthCookie("johannsw", false);
String lQueryStrings = HttpUtility.UrlDecode(Request.QueryString["state"]);
lQueryStrings.Replace('?', '&');
Response.Redirect("default.aspx" + "?" + lQueryStrings);
}
else
{
//I want to authenticate
String lState = String.Empty;
foreach (var key in Request.QueryString.AllKeys)
{
if (String.Equals("wa", key) ||
String.Equals("wtrealm", key) ||
String.Equals("wctx", key) ||
String.Equals("wct", key))
lState += key + "=" + Request.QueryString[key] + "&";
}
lState = lState.Remove(lState.Length - 1);
Response.Redirect(
"https://accounts.google.com/o/oauth2/auth?" +
"response_type=code&" +
"client_id=988046895016.apps.googleusercontent.com&" +
"redirect_uri=" + HttpUtility.UrlEncode("https://localhost/GmailSTS/login.aspx") + "&" +
"scope=" + HttpUtility.UrlEncode("https://www.googleapis.com/auth/userinfo.email") + "&" +
"state=" + HttpUtility.UrlEncode(lState)
);
}
}
but now I get an error saying "The HTTP verb POST used to access path '/WebSite1/' is not allowed."
Any hints?
Thanks!
Well finally I made it. Here is how I solved it just in case it helps someone else:

You are checking if the FileName is string.Empty, it sounds like you want to detect when the user clicked the button without selecting a file.
If that happens, the actual PostedFile property will be null (remember, the user didn't posted a file), you should use the FileUpload.HasFile property for that purpose:
protected void LbUpload_Click(object sender, EventArgs e)
{
if(FileUpload.HasFile)
{
LabelMsg.Visible = true;
return;
}
// ...
}
But I would recommend you also to add a RequiredFieldValidator.
More on validation:
Validating ASP.NET Server Controls
ASP.NET Validation in Depth
Are you sure that FileUpload and FileUpload.PostedFile is not null?
Either FileUpload or its PostedFile property must be null.
