Is it possible to convert a windows form application into a web application?
If it is not possible, how can I add the OpenFileDialog in a web application form?

I had another thread on this problem but I wanted to start this one so no one had to look at the code I posted in the other thread. I have a successful connection but want to display data from the SQL database on my website in my Windows form application. Here's the code I have so far. Used some of the ADONET Tutorial1 here. The table Ray Rover Activation has a number of different columns but to start out I just wanted to see if I could display data for the EmailAddress column.

I have written a program that interprets bar charts on the web and converts them into textual summaries. It is blind and visually impaired get more information during their web surfing. Anyways, right now all of the processing is handled on the user's machine and it is a very resource intensive program. So, I wanted to make it so the main computation was done by a server so that the user could simply click on a graph and get the summary instead of waiting while the computation was being done. Does anyone have a clue how to tackle this problem? If you need more information let me know.
View 8 RepliesI have a windows service that calls a class library. The call to the Class library from the windows form application works fine. But from the service I do get the desired output. The event viewer does not report any error. The service was working fine until the recently when the server got remastered. Any suggestions what might have gone wrong?
View 2 RepliesI'm developing an three layer ASP.NET application with C# and Visual Studio 2008 SP1. I'm using WebForms.
I'm wondering to convert that application to a Silverlight application. Maybe I can reuse a lot of code of ASP.NET layer.
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.
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.
View 1 RepliesI 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 had created ASP.Net Web Application named 'Traning Management System' (in English) for my company. Now my boss wants me to translate that application to Arabic language. He wants everything to be in arabic. I don't know how to do it. I searched in google and came to know about localization and globalization. I could not understand the topics. My application contains 1 master page, 5 .aspx pages. The pages mostly contains labels, textboxes, gridview, buttons and other controls. The project also contains reports.
