Exception Handling In Debug And Release Modes

Dear All
I created a project with full exception handling (Try, Catch) in all subs and functions, I know that this will affect the performance negatively but i'm in the testing phase and exception handling will be removed for the release
My question is: is there a way to keep the exception handling statements and restrict them to the debug mode and step over them in realease mode without having to keep two seperate copies for debug and release?

I was told that this was available in Visual Studio 6 so there must be something like it in VS 2003

Thanx in advance for help

Best Regards

Because the try/catch/finally blocks should be used throughout, not just in debug mode. The performance hit is not as great as some people expect. Even if it's inside a multi-iteration loop, you may be able to move the try block outside the loop.

It's a really bad idea to have try/catch functionality in your debug build and not in your release build. The code execution in the release will not be the same as the debug version. If you catch an error in the debug version, the release version should be able to cope with it as well.

I'll second Pete, exception handling is not just for debug.

If you make use of the Exception Handling in the Enterprise Library you can use the config file to adjust how the exceptions may be handled in either release or debug, without recompiling the app.

I should add that the performance of try/catch/finally is not as bad as people seem to think. The overhead really occurs when an error happens.

Errm. No, lots of people answered. They just didn't give you the answer that you wanted.

What you were talking about was the TRY/CATCH macros in Visual C++. These were compiled out of release builds because they effectively mapped in as:

#ifdef DEBUG
try
{
#endif

and so on. Now, as has been stated earlier, it is a bad idea to have debug code that does one thing and release code that does another. If you have an exception, you need to catch it and deal with it.

What you did wrong was to design your application to have try/catch in every method. This is normally bad design. Consider the following sample:

public void SetMyValue(string value)
{
    try
    {
       _myValue = value;
    }
    catch (Exception ex)
    {
      // Log the exception.
    }
}

What exception are you going to get here?

How To Dynamically Call a Webservice?

sstocker9-Jan-07 2:57

Is there any way to call a web service without making a web reference in your project or generating proxy classes using wsdl.exe? The project I am working on involves calling a number of web services listed in the appsettings section of the web.config. The app will eventually test these web services for responsiveness. One of the requirements is that it should be configurable from the web.config and should not have to be recompiled upon adding a new web service. I googled a few hours yesterday with little results. Any ideas?

Thanks,

Scott Stocker

I know what WSDL is. I am looking for a .NET way to load a web service without a web reference in my project. I know that a WSDL definition will probably be key in accomplishing a dynamic call to a web service but I was unable to find code to accomplish the dynamic call I am looking for.

Well since WSDL provides that capability perhaps you don't know what it is? To use a new web service your configuration information would supply the URL to the WSDL for the new service. Your code would then use the response WSDL to know how to format and where to send a request to the service. Of course the WSDL does not tell where to get the input parameters in your system or even what to do with the response data that might be returned from the web service so I don't really understand the point of all this, but there it is anyway.

Hi,

I uploaded site in one folder of the ftp location. When i open url, it is giving me following error.

Server Error in '/' Application.

Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".


<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.


<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>

=================
I tried to change all 3 modes of customErrors but same problem.

Can anyone help me please?

Thanks.
