How To Email Error Message In Catch
Feb 14, 2011
I have the code below which I now need to figure out how to not only display but also email it all to my email, this way should any user encounter a error we get to see exactly what is it.
Catch ex As Exception,lblInformation.Text = ("<h4>Unable to save data in database</h4>" + vbNewLine + "The error was '" + ex.Message + "'" + vbNewLine + vbNewLine + "The SQL Command which falied was:" + vbNewLine + "<strong>" + mySQL + "</strong>" + vbNewLine + "Please contact the Service Desk to report this error.").Replace(vbNewLine, "<br />" + vbNewLine) [code]...
in a new line above "booInsertedRecord = False" and then creating a new "Dim objEMail New MailMessage()" but then realised that won't work because it's msg is defined in the catch so not to sure what steps next to take.It's been a while since I used VB and I didn't need to use anything like this
Edit - @tzup ToString() shows
[The error was 'System.Data.SqlClient.SqlException: The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.The statement has been terminated.at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)

First I found that you can catch it and log it inside a catch, but this doesn't send an email.
Then I found out about using the Error Signal class. That worked, however what wasn't apparent from reading, is that it treats the error like normal, so when I signal the error it goes to the custom error page still, I don't want that to happen. What I want to do is catch that error, log it, send the email, but stay on the page the error happened so I can provide special feedback. I do not want it go to the custom error page.
EDIT: This is what I have and it redirects me to the custom error page.
Try
smtpClient.Send(mailMessage)
Catch smtpEx As SmtpException
errorSignal.FromCurrentContext().Raise(smtpEx)
Catch ex As Exception
errorSignal.FromCurrentContext().Raise(ex)
End Try

Here is the code copied from [URL] In asp.net code behind, I use try-catch try to catch any error but never catch it. In SQL database, if I rename Employees to Employeesx or change column DepartmentID to DepartmentIDx, record will not be deleted (it is right) without any error (it is wrong, suppose catch an error).
CREATE PROCEDURE DeleteDepartment
(
@DepartmentID int
)
AS
BEGIN TRANSACTION
DELETE FROM Employees
WHERE DepartmentID = @DepartmentID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RAISERROR ('Error', 16, 1)
RETURN
END
DELETE FROM Departments
WHERE DepartmentID = @DepartmentID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RAISERROR ('Error', 16, 1)
RETURN
END

By default in login template, in case user key in the wrong user name or password, the literal message will show the default error message, "Your login attempt unsuccessful..."What i trying to do is, I have a function in my system to disapprove a member, after the member is disapproved, he/she will not allow to login anymore. When the user trying to login, the default literal msg will show out. Is there any way i can do it more specifically like if the user enter the wrong password only, the literal msg show: "Wrong password entered" insteaed of the default msg?
Same goes to the change password control, for any error msg it just show the long msg but does not tell user whats wrong with the entered valueim trying to do something like if the user enter the wrong password, the literal msg show the one i wan to show.

Is there a way to catch a database exception and then redirect to an error page? I have a data access class that I use to make a sql connection and then functions that call it to execute my SQL commands. My problem is that if my database is not available I cannot catch that error. Here is the code I am using in my class:
Protected Function GetConnection() As SqlConnection
Dim ret_conn As SqlConnection
ret_conn = New SqlConnection(System.Web.Configuration.WebConfigurationManager.ConnectionStrings("EUCNET00617").ToString())
ret_conn.Open()
GetConnection = ret_conn
End Function

I come from a VB environment. I'm looking at 2 different file extensions. If one doesn't exist look at the next. I was hoping to use the try/catch function. I can get it to find the first extension but not the second. Here is my the try/catch part of code:
try
{
string website = xAll;
Response.Redirect(website);
}
catch (FileNotFoundException)
{
string website1 = xAll1;
Response.Redirect(website1);
}
The error dialog that pops up shows Connection Error in the title and a yellow exclamation point with File Not Found! I thought the FileNotFoundException would work(?).

A developer has created a custom control in ASP.NET using VB.NET. The custom control uses a repeater. In certain scenarios, the rpt_ItemDataBound event is encountering a data error. My goal is rather than having the user see the yellow screen of death, give the user a friendlier error explaining exactly what the data error is. I figured I would be able to use a Try/Catch block as shown below throw the exception, however, it appears that the event has nowhere to be thrown to and stops executing at the "End Try" line.
Protected Sub rpt_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rpt1.ItemDataBound, rpt2.ItemDataBound
Try
ProcessBadData...
Catch ex As Exception
Throw ex
End Try
End Sub
In VB.NET, I can find where the repeater's DataSource is being set, however, I can not find a DataBind event. how I can capture the exception in this ASCX control so I can report it to the user? Edit: The stack trace looks like this. There is another repeater within the repeater that is actually causing the error (rptOther) and I'm able to catch the error, but I can only throw it to the rpt_ItemDataBound. I can't figure out how rpt_ItemDataBound is getting called without a DataBind event.
at Company.WebForms.Control.rptOther_ItemDataBound(Object sender, RepeaterItemEventArgs e)
at System.Web.UI.WebControls.Repeater.OnItemDataBound(RepeaterItemEventArgs e)
at System.Web.UI.WebControls.Repeater.CreateItem(Int32 itemIndex, ListItemType itemType, Boolean dataBind, Object dataItem)
at System.Web.UI.WebControls.Repeater.CreateControlHierarchy(Boolean useDataSource)
at System.Web.UI.WebControls.Repeater.OnDataBinding(EventArgs e)
at System.Web.UI.WebControls.Repeater.DataBind()

I am injecting an error purposly but nothing is happening, I get no error that pops up and even if I write text to the label nothing pops up at all.

- I have a situation in which I must execute a dynamically built stored procedure against tables that may, or may not be in the database. The data retrieved is then shunted to a VB.Net backed ASP based report page. By design, if the tables are not present in the database, the relevant data is automatically hidden on the report page. Currently, I'm doing this by checking for the inevitable error, and hiding the div in the catch block. A bit kludgy, but it worked. I can't include the VB code-behind, but the relevant stored procedure is included below.
However, a problem with this method was recently brought to my attention when, for no apparent reason, the div was being hidden even though the proper data was available. As it turned out, the user trying to select the table in the dynamic SQL call didn't have the proper select permissions, an easy enough fix once I could track it down. So, two fold question. First and foremost - is there a better way to check for a missing table than through catching the error in the VB.Net codebehind? All things considered, I'd rather save the error checking for an actual error. Secondly, is there a preferred method to squirrel out a particular OLE DB error out of the general object caught by the try->catch block other than just checking the actual stack trace string?
SQL Query - The main gist of the code is that, due to the design of the database, I have to determine the name of the actual table being targeted manually. The database records jobs in a single table, but each job also gets its own table for processing data on the items processed in that job, and it's data from those tables I have to retrieve. Absolutely nothing I can do about this setup, unfortunately.
DECLARE @sql NVarChar(Max),
@params NVarChar(Max),
@where NVarChar(Max)
-- Retained for live testing of stored procedure.
-- DECLARE @Table NvarChar(255) SET @Table = N'tblMSGExportMessage_10000'
-- DECLARE @AcctID Integer SET @AcctID = 10000
-- DECLARE @Type Integer SET @Type = 0 -- 0 = Errors only, 1 = All Messages
-- DECLARE @Count Integer
-- Sets our parameters for our two dynamic SQL calls.
SELECT @params = N'@MsgExportAccount INT, @cnt INT OUTPUT'
-- Sets our where clause dependent upon whether we want all results or just errors............................

I have an asp.net control that contains a grid view sitting on top of an Ajax update panel. The control has been added to a sharepoint page. When a button is clicked, some server code is called to store the contents of the grid. If the server code throws an error, I want to spit out a javascript alert displaying the error message, but for some reason the error that bubbles up from the server is the generic 500 server error, which doesn't contain any details of the original error.

have code on a web form -- when you hit the button "send emails", it executes this sub which reads an SQL database table and sends emails one by one -- however I get this error above -- anyway to check it and skip to the next email? Some emails in my table have name@test.co.il for example, so it seems this causes this error.

I have try{}catch(Exception ex){} in the right place:
Code:
protected void Button1_Click(object sender, EventArgs e)
{
try
{
// all processing occurs inside here
}
catch(Exception ex)
{
}
}
I even created a global.asax file and on the Application_Error event, I wrote a code that would email me the error (and i'm not getting an email regarding that error when I get the error shown above). I know for a fact that the thread is going inside the "try" statement because I send emails to myself whenever it finishes certain codes inside of it. So how come I'm getting that error in my browser instead of it being handled in my "catch" statement? I have two problems here, one, why is the exception not going to my "catch" statement, and two, why am I getting that error in the first place.
Note: my web app calls a webservice.
