Hi,
I keep on getting this pain in my butt error whenever I change some code and resubmit to website:
Access to the path "C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files\webservice1_wsmnmhzdata\7aaddb50\25b57516\hash.web" is denied.
Any ideas how to stop this from occuring?
Thanks,
JJ

Does this happen when you change the code for the WebService or when you change the code for a consumer project of the webservice? Is the WebService and the consumer part of the same solution? Does the consumer project have a WebReference to the webservice or a project reference?

Change code for the webservice. and yes the consumer project uses a web reference to the webservice.

The message is coming up probably because your service is still running on the web server. When you compile the code, it can't replace the running version of the executable. Do you still have a browser window open when you test your project?

You have to add a reference to the DLL.
Therefor go to the solution explorer, right-click on References and select "Add Reference". In the dialog that opens, search System.Web.dll entry in the ".NET" tabpage, double-click on it and close the dialog with OK.

It seems like you want them to search for you. As a standard suggestion, please use the ability to search CodeProject and then use Google.

I won't dignify your question with an answer.
Yes, I program in VB6, but only because I'm addicted to eating!

I was a VC++ programmer. Now I am learning C#.
In VC, you can use SendMessage() or PostMessage() to send or post a message to
a window. How can I do this in C#?

You have t use the same win32 API for it , for the sample of how to use theem in C# see this site:
http://pinvoke.net/[^]
Search for these APIs to see sample codes.

i am not able to run a project in C# because i dont have a certain Microsoft.Win32.Interop in my libraries...would someone please tell me where i can get that library...i am presently using Visual Studio.NET 2002

What's the error that your getting? More than likely, you're not missing anything from the .NET Framework SDK. You COULD be missing an Interop .DLL that is generated when you import an ActiveX control and use it.

i am trying to run a project which is sort of a calendar and generates a response on the shceduled date....the actuall error that i am receiving is ..
"The referenced component 'Microsoft.Win32.Interop' could not be found. "
and "The type or namespace name 'Interop' does not exist in the class or namespace 'Microsoft.Win32' (are you missing an assembly reference?)"...i am really sorry but i am a newbie and would really appreciate if you can help me with the problem.

OK. Did you reference any ActiveX components? What references have you made?
Plus, post the top of your code also, through the Windows Form Designer section.

the top od my code looks like this..
using System;
using System.Drawing;
using Microsoft.Win32.Interop;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace WindowsApplication9
{......

There's your problem... Get rid of the line using Microsoft.Win32.Interop. There is no namespace by that name so it's not going to work. Where did that come from? No application I've seen needs that line, which won't work anyway...

Ummmm...The databae code that your using is coming from a really OLD sample that worked under VS.NET Beta 1. The ADO namespace was replaced by SqlClient and OleDB namespaces back in VS.NET Beta 2, I think!
You'll have to rewrite your database handling code to the newer namespaces, depending on where your database is, either SQLClient for an SQL Server, or OleDB for an Access database.

I can't wrewrite your code for you because I simply don't hvae the time. I can point you to a page that will show you how to get a connection to an Access database, then you can follow the links, for retrieving records and such, from there.

please help me!
How can get IP Address from local machine?
Thank you very much!
|
|
|
|
|
hi,
Use the following code to get the local IP address
System.Net.Dns.GetHostByName("localhost").AddressList[0].ToString();
If you are not intending to use "localhost" then you can use the name of your computer as well.
Hope this solves your problem.
regards,
Aryadip.
Cheers !! and have a Funky day !!
