can anyone explain to me what is the error... im using c# .netNo connection could be made because the target machine actively refused it (ip address)code behind:
MailMessage mail = new MailMessage();
mail.To.Add("emailto");
mail.From = new MailAddress("emailfrom");

But the issue here is that I am using a post request trough an WCF app. This will work fine on my home PC call(web form - web app) - from the work PC call. It will not work from the WCF service I use that uses LOCAL IIS 7 or my work PC (that an app I created works fine through my local PC).
So I tried various IIS manipulations, made it iis express, made it visual studio IIS, made it local IIS, made it https, http, nada.
When debugging the code and it goes to the getrequest - from site line, it will break.
What is going on here? Is it the IIS? The wcf works flawlessly on about 20.000 lines of code but the post call to another vendor will break.

View 1 RepliesI have a simple web app that queries a server based database. I have tested with both a simple MySQL table and Access tables. The problem is the same whatever 'backend database' that I use. When I run my web application under the VS 2008 debuger then all works fine. No problems with the code. I then publish my web app to either my local IIS or to a different PC's IIS on my network. I then get 'intermittnet' problems reading the data tables. The connection strings are fine. I get a connection. It is when I try and fill the tables that I get errors. The web app just seems to 'hang'.
If I publish to a different IIS on my network (on a different server) the I get the same problems. If I reboot the IIS machine then I seem to be able to get to my data for a while before the IIS seems to 'lock up' and I can't read data anymore. Is this an IIS/authentication/resource issue?

I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:

I have a Windows Service I have developed in Visual Studio 2005 (C#).
It accesses a database using a connection string in machine.config.
On my Windows XP Pro 32bit (SP3) machine, it works correctly.
On my new Windows 7 Pro 64bit machine, it throws "object not set to an instance of an object" when it gets to the line where it's trying use the connection string.
This is the 'object' which is not set in Windows 7:
ConfigurationManager.ConnectionStrings["MyDatabase"].ConnectionString
The machine.config has the same connection string set up on both machines.
A .Net 2 website transferred to the Windows 7 machine has no problem accessing the same connection string.
I have tried a bunch of different permissions on the machine.config and its containing folders, and setting the service to log in as Admin, but I don't know exactly what permissions are required.
