Is there a way to write an small application that will run both as a windows forms application, and within an asp.net application?would some sort of widget or even something in silverlight do this?
View 3 RepliesI'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 a ASP.NET application. From that, User register, User will get email after registration. My Req : When user click on link provided in email. Then it should go to my ASP.Net application page . That page should install a wincows application on Client system through web ( I was inspired by Microsoft Windows update from Microsoft site)
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?

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.

View 2 RepliesWe've inherited this ASP.NET website. We've already converted it to a web application for different reasons that doesn't matter right now.
But there are 2 folders with 2 .aspx pages inside that does some really ugly stuff (creates a new aspx file with its corresponding code behind and save it inside one of those folders).
So when the proyect was a simple website, that worked, because the created pages on runtime were compiled at request. This is not applicable to a web application.
We don't have time to re-code those ugly pages and do it as it should. So, is there a way to have those 2 pages (and the generated-at-runtime ones) excluded from the project and inside a website that is compiled at request?
I see there are 2 possible scenarios as to the session handling:
Open one single ISession per request. Open it at request start and close it at request end.Open one ISession per conceptual "unit of work". Many sessions are created for a request.
The approach #1 is the one I'm doing now. I'm a little bit worried about it because, although it works, it's a little bit difficult to debug. For instance, I have an object not being saved (even though I ordered it to) and I'm having trouble debugging since there's a LOT of things happening during a complete request life-cycle.
The approach #2 seems to be the standard best-practice (not sure about ASP.NET) and I'm sure it's pretty easier to debug. The problem I see is about inter-session communication. For instance: My Page class holds a reference to the User, which is a persistent object. Many of the operations receive the user as parameter. As the user belongs to a different session, I can't pass it as a parameter.
I'm biased to #2, but I don't know if it's the best practice, nor how to deal with cross-session object.
I'm developing a Web tool in ASP.NET 2.0 with AJAX . Its working fine in Local Server. When i deployed it in Development Server and executing the Application , I got an error
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(),
response filters, HttpModules, or server trace is enabled.
Details: Error parsing near ' I didn't use any Response.Write in the Application. How can i solve this issue ? Any body knows the solution for this ?
i am working on a asp.net webforms app, and i have to create 'dynamic order lines'That is : you select a product and a quantity, and the amount is calculated.
To visualize: this is on one 'line', so forst product dropdown, next to it the quantity textbox and next to that the amount label.
Then you click 'add another product', and another 'line' is added with a product dropdown, quantity textbox and amount label.
So you can click add and add and add....
Now i was thinking how to implement that, and i came up with two choises:
'add html client side' and 'add user control server side'
The first looks more fancy of course, but i also have to create some server side code to generate the lines again, when the user says 'go' but after validation i have to warn the user for example the amount was over credit or the quantity was to high. Then i get the 'client side' added html, and i have to reproduce that in my code behind, am i right?
On the other hand (add user control server side), i have to create a new user control on 'and another product' postback, which might look easier in the beginning because it's all strong typed, and the client side (jquery / javascript) isn't?
And one more thing: there is a possibility (they are not sure yet) that this functionality is wrapped within a 'section', with an address box and call it an order.And then: the user can add that 'section' also multiple times, so he can create multiple orders in one page, so i have to create multiple sections for an order, and within that order have the possibility to add another product.It looks like it will be hard to do this client side, especially with generating id's?
can I include normal asp.net pages (webforms or mvc) in a Dynamic Data web application?

View 1 RepliesI 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 am looking at how best to prevent a single user account logging on multiple times in a webforms application. I know that MembershipUser.IsOnline exists, but I've read a few forum and blog entries suggesting that this can be unreliable, particularly in scenarios where a user closes a browser (without logging out) and attempts to logon with a different machine or browser.I looked at implementing a last past the post type system; when a user logs on older users are simply kicked off. It seems that FormsAuthentication.Signout() only works for the current user.
