Re: Retrieving the COM class factory for component ... Access is denied

What version of IIS Server are you using?

Well you should reinstall the Crystal Report run time on the server again to re register the class object.

I know what the error code is from c++ programming, and it means you have to elevate your permission level, but I find it strange that you should have to do that.

So I guess if your running on IIS6, then network service has to have permission on the webform, and for IIS7+, the application pool identity. Mayne the program writes temp files that need permission to write or modify.

Hi all,

I am using entity framework 1.0 for my .net 3.5 application, is it good to use entity framework with Views or without views in the database.

Which is more efficient?

Hey i wanna start a discussion on try catch blocks. I read a lot of conflicting opinions on wether or not to use them and where or where not to use them, I just want a diffinative answer. Cheers.

Always use them around any code that may throw an exception that you need to deal with.

One of these days I'm going to think of a really clever signature.

Hey the thing is I know exactly when and where to use them it just seems that all through my code there are 100's of try catch blocks and I read very conflicting articles on wether or not this is best coding practice.

Although everyone have their own opinion but the main important thing is user should not experience unexpected behavior. if there is something going wrong you need to catch and that could be possible through try..catch and logging the messages.

so resolving errors are more important then best practice... keep coding... Smile | :)

I understand that with tools like Codeit.right and The Visual Studio Analysis that Try Catch(s) are to be used sparingly and to catch only certain types of errors. You should try to wirte tests into the code in order to narrow the parameters of the code so that you will be able to report back to users problems. Hiding errors in Try / Catch in not the proper use of the machanic.

Hope this sheds some light on the use.. Try running the code by removing all the Try/Catch and if there is a better way like a If/Then that can cover the error then it is so much better.. in Addition Try/Catch are generally slower.

Regards.

If you are interested in executing a certain block of code irrespective of whether an exception occurs or not and still worry about catching an exception you might use the try-catch-finally block. Even if a goto statement is present in a try block, the control gets transferred to the label in the goto, only after executing the finally block.

You should try and use them in your code as much as possible, especially if you suspect a particular error may crash your programme.

Creating WCF client proxy using svcutil.exe

indian14329-Nov-12 9:14

29-Nov-12 9:14

Hi,

I had been given a WCF service endpoint for net.tcp and http binding both. I want to generate proxy for this wcf service. But when I am running the svcutil from VS command prompt as administrator, it is giving me the below errors.

When I run the

C:\Windows\system32>svcutil.exe /language:vb /out:D:\WSDLRepository-Proxy\DocRetrieveService\DocRetrieveService.vb /config:D:\source\SourceCode\StayatWork-VS2010\BusinessLogicLayer\app.config http://xxxxxxtumecr21:8000/FilenetDocRetrieve/DocRetrieveService?wsdl
command

I am getting the below error

WS-Metadata Exchange Error
    URI: http://xxxxxtumecr21:8000/FilenetDocRetrieve/DocRetrieveService?wsdl

    Metadata contains a reference that cannot be resolved: 'http://lnidaptumecr21:8000/FilenetDocRetrieve/DocRetrieveService?wsdl'.

Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).</Text></Reason></Fault>


HTTP GET Error
    URI: http://xxxxxtumecr21:8000/FilenetDocRetrieve/DocRetrieveService?wsdl

    The document was understood, but it could not be processed.
  - The WSDL document contains links that could not be resolved.
  - There was an error downloading 'http://localhost:8000/FilenetDocRetrieve/DocRetrieveService?wsdl=wsdl0'.
  - Unable to connect to the remote server
  - No connection could be made because the target machine actively refused it 127.0.0.1:8000

If you would like more help, type "svcutil /?"

But when I run the

svcutil.exe /language:vb /out:D:\WSDLRepository-Proxy\DocRetrieveService\DocRetrieveService.vb /config:D:\source\SourceCode\StayatWork-VS2010\BusinessLogicLayer\app.config http://lnidaptumecr21:8000/FilenetDocRetrieve/DocRetrieveService?wsdl
Command 

I am getting the following error

Error: An error occurred in the tool.

Error: The given path's format is not supported.

Can anybody please help me in resolving it, I want to generate a proxy for my wcf clinet without using add service reference.
Because I dont want to make my client environment dependant. Any link or any kind help is great. Its urgent please help me.

Hi,

Just give this a try, not sure about that. but instead of single slash in config file path use double slash. all the directory file path with double slash(\\).

so your command become,

svcutil.exe /language:vb /out: D:\\WSDLRepository-Proxy\\DocRetrieveService\\DocRetrieveService.vb /config: D:\\source\\SourceCode\\StayatWork-VS2010\\BusinessLogicLayer\\app.config http://lnidaptumecr21:8000/FilenetDocRetrieve/DocRetrieveService?wsdl

Controls in asp.net consist of several categories such as HTML elements, but can be used directly on a web form or in code behind.

So web designers just starting out can drag and drop a control from the toolbar onto a web form, and experts can just type pure code to build sections of a web page.

If you have a specific question about controls, feel free to ask.
