How To Get Exception Type Without String Name (ex.GetType().FullName) Comparison In Page_Error Handler
Dec 13, 2010
Is there a better way to do this than to check for Exception string?
I would rather have this catch-all error handled on the page, but for SOAP exceptions (web-service calls) I need to log the details of the actual exception that occured on the server, not the client.
The ".Detail.InnerText" property isn't in a generic exception, and can only be gotten after casting a generic exception to a SOAP exception.
[Code]....
I would think there is a way to get at the underlying Exception's type without using string comparison.
I want to log all errors happened in my App to sql db. I'm passing all exception properties like (ex.Message, ex.Source, ex.StackTrace, ex.TargetSite and ex.InnerException) to stored procedure.
The problem is that when I try to pass the ex.InnerException as string to stored procedure I got this error:
Cannot implicitly convert type 'System.Exception' to 'string'
I tried ex.InnerException.ToString() and Convert.ToString (ex.InnerException) but no success.
I have a table with userID's stored in it and I want to SELECT a user out of that table to see if it's the current logged in user. I'm using this as logic to determine what action a button click will do. For example the button click will do something like this:
[Code]....
My broblem is getting the UserName from my table of data. I've tried it like this:[Code]....
But when I try debugging it shows that CurrentUser's value = Nothing
My UserNames (ToUser) contain letters and numbers (nvarchar(30)).
comparing integer values which are actually in string (varchar(9)) right now...I'm trying to do the following in a stored procedure..
SET @MinProjectYear = SELECT ProjYear FROM P_A WHERE ID = @ID SET @MaxProjectYear = SELECT ProjYear FROM P_A WHERE UserId = @UserID AND... IF EXISTS(SELECT 1 FROM P_A WHERE MinProjectYear <= MaxProjectYear) return true
The MinProjectYear and MaxProjectYear are varchar(9) values stored as "2007-2008", "2009-2010", etc. How do I split and compare the years?? i.e. check if 2007-2008 <= 2009-2010 ??
I am wishing to retrive picture stored in sql server database to web form using gridview control. I have created a Handler.ashx file with following coding:
[Code]....
And in the aspx page I am calling this as:
[Code]....
But when I am executing this project, it prompts following error:
I have simple 3 tier web application and have mostly CRUDE functionalities. Recently I required to add new console application to the existing solution in which I call data layer methods for retrieving data from DB but I get an exception "The type initializer for threw an exception."When I debugged I found that the exception is thrown at datalayer on first line of class where I get connectionstring from
web.config, the code is public static readonly string CONNECT_STRING =
Now if I hardcode the connection string value like public static readonly string CONNECT_STRING = "Data Source=XYZ;uid=sa;password=XXX;initial catalog=ABC;"
it works fine.I don't understand what is the issue here as web application works fine with this datalayer.
I have a FormView that allows a user to register for a company event. I want to do a couple of things with this form.
1. I need to write this data to a MS SQL database
2. I need to send an email confirmation of their registration to their email.
I know how to do both of these things, but i am having trouble doing both at the same time.
It would be nice if I could do it in one click, but I coded it into two pages to try to help simplify it.
The first page allows the user to input their information into a formview and when they click the submit button, it places those answers into session variables:
[Code]....
[Code]....
The Second page confirms the users information by taking those session variables and placing them into labels:
[Code]....
[Code]....
However, after I place information into the formview on the first page, it throws up this error:
"Conversion from type 'TextBox' to type 'String' is not valid".
I have this error "The given value of type String from the data source cannot be converted to type datetime of the specified target column." when I used sqlbulkcopy to do the transaction
I have a gridview which I'm trying to get the display of phonenumbers listed in a certain display format; (xxx) xxx-xxxx.If I have the code such as this, it displays the unformatted phone number and (000) 000-0000 for the null items.
I seem to be having issues with posting forms with DropDownLists. I've looked all over the net and tried various solutions, but none seem to work for me.
I'm getting the following error: The parameter conversion from type 'System.String' to type 'Models.Organization' failed because no type converter can convert between these types.
Here's my ViewModel:
[Code]....
Here's my controller:
[Code]....
The objects are generated by ADO.NET Entity Framework. Organizations is its own object, but also a property of Profile (each user belongs to one organization). Now I understand what the error message is saying, just not sure how else I'm supposed to do this.

I'm trying to pass email addresses from an array to a stored procedure, then display the results in my gridview. I get the following error:No mapping exists from object type System.String[] to a known managed provider native type.On this line: Dim DR As SqlDataReader = MyCommand.ExecuteReader
I'm busy writing a handler to serve various documents for download or presentation in web forms pages. The documents range from various image formats, to PDF, to MS Office documents, to generic binaries. My basic draft of the download process is as below:
[code]....
However, I have some misgivings about lumping all documents together as application/octet-stream, and I would prefer, if feasible, to use a more specific content type per document type. I have a DB table for document types where I could store this. Am I going in the right direction, and if so, where can I find a suitable starting list of content types for document types?
I have a new virtual server, subsite. but I get the feeling I may be still be inherting from the root config! Even though I have included <clear/> within both the <connectionString> and <httpModules>.
The main website works (web1) along with one of the subsites (web2) however the 3rd subsite (web3) gives the below error.
e.g.
http://web1
http://web1/web2
http://web1/web3

I have created a chart control webpart and trying to deploy onto sharepoint2010 page. I am able to add the standard webparts. When it comes to the webparts related to chartcontrols I get the following error.
In the project I have some custom WebUserControls for form elements (they encapsulate some standard validators and other system specific functions). My user controls are "DropDownListField" and "TextBoxField". In the code behind of a page I have this code:
string parameterValue = null; foreach (object control in myMultiView.Views[myMultiView.ActiveViewIndex].Controls) { if (control.GetType() == typeof(DropDownListField)) parameterValue = ((DropDownListField)control).Value; if (control.GetType() == typeof(TextBoxField)) parameterValue = ((TextBoxField)control).Value; }
For some reason the "if" statements always return false even when I step through the code and see that "control" is getting assigned my web user control. This code is in another place in the project exactly the same except in the other location the standard .net controls "TextBox" and "DropDownList" are used and in the other location the code works. why this wouldn't work with web user controls?
I have a web service and its methods return a class which is name WSResult. WSResult has 2 properties. One of property's type is int and the other one's type is object. I want to return some different type with this second property.

We have an asp.net 2.0 application in which we get the exception of type 'System.OutOfMemoryException' whenever value is retrieved or stored in viewstate. It does not happen when we test it in local PC but when it is deployed on application server, the exception is thrown.
Basically, what I did is that: I have a table in SQL database and some of data fields allow null. I built Objectdatasource through dataset. When I built update page using dataset. It generate the following error before showing the update page correctly. It seems I have issue to retrieve the null value from the database through using objectdatasource through dataset. Any suggestions?An unhandled exception occurred during the execution of the current web request.
