Exising .net 2 app migrated to .net 4 and moved to an IIS7 Windows 2008 R2 server. We used to be able to run some code on the web page to export some stuff to excel. Now, when we do... we get the following error: The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {00024500-0000-0000-C000-000000000046} and APPID Unavailable to the user d"omainusername" SID (S-1-5-21-2084383492-816144152-925700815-4150) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool. I did wonder if it may be to do with the authenticated user being on a different domain to the webserver - where we see this error?

We have a website portal hosted in Windows 2003 server. For security reasons we are using different windows Login user say (xxxx) for signin other than Administrator. Now with this user (xxxx) name I installed .net Windows Application. It was working fine. For some reasons I renamed the original windows Login user(xxxx) to different say (yyyy). Now this .net Windows Application is not working with (yyyy) and even it is not allowing me to uninstall it.
i have created one windows application in c# .net and its working fine in windows xp, but when i try to install the setup in windows 7 or vista,the setup never runs.. should i have to write some code for it.
I'm experiencing a to me mysterious error when sending e-mails through a SMTP-server from an ASP.NET web application. I get the famous error "unable to relay for xxx@yyy.zzz". What's mysterious to me is that when I cut and paste the exact same code that sends the e-mail into an usual .NET Windows Forms application, send the e-mail with this application, it all works just fine. This made me think that perhaps the problem is that the ASP.NET application runs as NETWORK SERVICE while the Windows Forms application runs on a domain user account, but it turns out that I have another ASP.NET application sending e-mail through the same SMTP-server running under NETWORK SERVER at the same IIS, and this application does not experience this problem.
I've further tried to send e-mails through the SMTP-server manually by telnet the smtp-server on port 25 and running the SMTP-protocol manually, and it all works fine. The SMTP-server is not configured with any kind of authentication or SSL.
Another mysterious fact is that the ASP.NET application can send e-mails from an adress within the same domain to an e-mail adress within the same domain, but not to any adress outside of the domain. But the Windows Forms application, that uses the exact same code, can send e-mails from any adress to any adress both within AND outside of the domain.
So to summarize:
The ASP.NET application can send e-mails from addresses within the domain to adresses within the domain, but not to addresses outside of the domain. A Windows Forms application running the same code on the same computer can send e-mails from ANY address to ANY address. Another ASP.NET application on the same IIS running under the same account (NETWORK SERVICE) can send e-mails using the same SMTP-server from ANY adress to ANY adress. There is no authentication configured on the SMTP-Server. Both the ASP.NET application and the Windows Forms application utilizes the System.Net.Mail.SmtpClient class to send a System.Net.Mail.MailMessage.
The code that sends the e-mail massage is:
private void button1_Click(object sender, EventArgs e) { MailMessage mesasge = new MailMessage(txtFrom.Text, txtTo.Text, "Test mail", txtBody.Text); SmtpClient client = new SmtpClient(); if (!(string.IsNullOrEmpty(txtUserName.Text))) //Is false since txtUserName.Text is empty client.Credentials = new System.Net.NetworkCredential(txtUserName.Text, txtPassword.Text); client.EnableSsl = false; client.Host = txtServer.Text; client.Port = 25; try { client.Send(mesasge); } catch (Exception ex) { txtResponse.Text = ex.Message; } }
As far as I can understand, this should be a matter of configuration rather than coding issues.
Recently deployed my web app on Windows Server2008, IIS7 (with Office installed). After chasing (& catching) various other errors, I'm facing one I'm not sure even where to begin.
On Cassini (visual studio dev server) everything worked flawlessly (reading excel through excel interop).
On w2008 IIS it throws vague error:
Value cannot be null. Parameter name: o [ArgumentNullException: Value cannot be null.....
Currently, I'm going to add null check and see if things get better but I do suspect that it just blows up and disposes on finally block before it even starts reading anything.
Tried to set application pool to run under localsystem, but that didn't change anything.
Currently we are running an application build in VB6,ASP,Commerce Server2000 and Sql Server 2000. This application is running in Windows 2000 server.Now we are planning to migrate Windows server 2000 to Windows 2008.Will this application run in Windows 2008 or do we need to upgrade this application to dotnet and Sql 2008?
I have some common dlls that are referenced by both a windows service application and a asp.net web application. I don't want to make separate copies of the dlls and I also don't want to put those dlls into GAC. I try to put that service application under the same root folder as the web application so that they can share the same bin folder. I am not quite sure if this will cause any problems? I did find the web application had random session timeout, but not very often. Not sure if it was caused by the shared dlls.
I have a simple windows form app that I need to get the file path for. I am placing a config file in the same directory and I need to be able to get the path to that file.
I have used Application.CommonAppDataPath but that returns the path with 1.0.0.0 at the end.
and Applicaiton.StartupPath but that returns the path with indebug at the end
Is there anyway to get the path to just the main file directory without anything appended to the end?
why is it that the exact same codes that i use to create a Windows application, which is able to work, does not work on a Web application? i created a windows application using c# and socket programming language. i will be connected to a remote server and through the windows application, and i will be able to send the "byte[] msg" to the server and activate the LED lightbulbs attached to the remote server. that exact same codes works well on the Windows application. however, when i create another Web application using the same exact codes, i does not have any error yet i am not able to activate the LED lightbulbs attached to it. is it that through the web or internet explorer i am not able to send the "byte[] msg" correctly? or that i sld modify "byte[] msg" to suit the web usage? or any other reasons?
I have a windows application and a web application. The windows as well as web application has a login page. The username and password are same for the windows and web application.
In the windows application, the user enters the username and password. With this username and password in windows application, is it possible to log into the web application? If yes, How to pass the data from windows application to web application, thereby logging into the web application. Is it possible to pass the username and password from a windows application to a web application?
I have a web page where I used a gridview and a button.When selecting rows in the grid and click on the button another windows application fires.I need to pass the values of the selected rows to the windows application.
Rightnow I'm saving the values in an xml file and fetch the values in the windows application.But this is not practical when creating xml files with random numbers(Scan125.xml,Scan7867.xml,etc).

What are the different ways in which a web application can communicate to a windows application? I have heard that activex control events can be handled in javascript to achieve this.
Does WCF or any new technology provide a better implementation for this?
Can the publish/subscribe architecture be used here?
This may sound like stupid question, but still need some clarification on this...When it comes to application development in a company for internal use, what should i use windows application and web application ... which one is more suitable and why ?
