2 Questions about serialization and error coding...

Posted By:      Posted Date: September 23, 2010    Points: 0   Category :ASP.Net

1. When using serialization on a controller any associated/aggregated classes returned an error that they weren't serialized. If I add serialization to these classes will they load automatically when I deserialize the controller class saving me many lines of code?

2. Slightly more complicated. I'm doing a project that requires a text editor to have error correction for a particular language like VS does for c#,VB etc. This is going to be like BlueFish editor where you select the language and it tells you if there are mistakes with the code etc. As a small project it won't have full functionality but it's the code structure and OO technique that's important. Can anyone advise me or show example of the best and most efficient way to achieve this? I'll be doing my own research but I don't want to start it and after a week find it's unreliable or unefficient. If anyone has experience in this then let me know Thanks.

WCF de serialization error -- finding the erring field (urgent)


Hi Folks,

Need some urgent help. I am writing a WCF client which calls a service. Now, while de serializing the response from the service, the WCF client errs out with 'De serialization error'. In the inner exception, it gives the co ordinates of the erring field (e.g.: 5, 113). This de serialization error in my case is caused because of data type mismatch between the data sent by the service, and that in the .Net wcf proxy.

My question is how do we pin point the exact field based on the co ordinates given in the inner exception, if at all we are using any http debugger like Fiddler. I am finding it very difficult to exactly pinpoint the erring field based on the inner exception.

Thanks a lot,

Coding / Programming Tips for C#

Using proper guidelines and a template-framed style of coding will really helps developer to enjoy the coding with more understandable, reliable code and application development.

The void is invariant

while back I described a kind of variance that we've supported since C# 2.0. When assigning a method group to a delegate type, such that both the selected method and the delegate target agree that their return type is a reference type, then the conversion is allowed to be covariant. That is, you can say:

IsapiModule Error 500 Issue


I am about exhausted trying to figure out this error:

HTTP Error 500.0 - Internal Server Error

Description: The page cannot be displayed because an internal server error has occurred.

Error Code: 0x8007007b

Notification: ExecuteRequestHandler

Module: IsapiModule

Requested URL: http://localhost:80/ReportServer

Physical Path: c:\Program Files\Microsoft SQL Server\MSSQL.2\Reporting Services\ReportServer

When I enable Failed Request Tracing Rules and view the log output I am supposing that the actual problem is in the 2nd call where there are 2 backslashes before the actual filename in the specified path:

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance
