Can anybody give me further help??

No further help can be given for something as unspecific as "Server Error". We need to know more information. If you can, browse to http://localhost/trace.axd. If it doesn't exist, turn on logging in /Web.config. If tracing isn't enabled and you're browsing to localhost, then the page handler for trace.axd should also tell you how to enable it.

Once that's done and you've reproduced the error, what exception are you getting? What does the exception text say?

Once you find all that out, post it to the ASP.NET forum. This forum is for C# questions not specific to ASP.NET since there's already a forum specific to ASP.NET.

i'm creating a tool that requires constant detailed, fancy, colorful logging. The richTextBox provides pretty much most of what I need, but i find it unreliable. When text is being sent to the RTB constantly, attempting to color code each of the lines, it will miss some of them. and in some cases, when text becomes very large, it starts throwing exceptions when things like color coding are used.

so is richtextbox all i got when it comes to trying to do a lot of text logging, with different colors, fonts, etc?

i thought about replacing the rtb with a webbrowser control, and do everything in html, but then i thought how would i do this. i coudl have to recreate the entire page every time i made a change and refresh the browser, right? is there a way to just "add" text to an existing page through the webbrowser control?

thanks

Hi,

I am searching for the best regex mail pattern with C#.

Thank you,

I don't recommend hard-coding the TLD (top-level domains). Change that to ([a-z]{1,}) instead and let DNS do its job.

Following that logic, you wouldn't need a Regex at all. Just try to send the email, using any random string as the address, and "let DNS do its job". ([a-z]{1,}) validates lots of invalid email addresses. The last time I checked, only the TLD's, plus 2 letter combinations were valid. Its best to spell this out explicitly in the regex.

I think Heath meant actually checking your DNS server for a valid MX record. Smile | :)

And not blindly sending mail...

So, by your token it's good to hard-code that which changes often. What leppie said is right, and at the very least if you're going to hard-code these values read them from a .config file instead (like from <appSettings> or your own configuration section.

Should one honestly have to fix, recompile, and re-deploy the assemblies that use this each time a new TLD is added?

Dynamically constructing a form in a generic container

2-Oct-04 5:10

I agree with you, that hard-coding those vales could make it hard to maintain and update the application. Depending on the intended use, there are always tradeoffs. Read from a config file, hard-code them, use your ([a-z]{1,}) method, and probably a few others. The goal of my original post was to give a good starting point for an email regex, and I considered the example from Jeffrey Friedl's book to be pretty good. Thank you for pointing out ways in which it could be improved in practice.

I'm not sure if what I'm wanting to do is possible in C# or not, but I thought I'd pose the question. In C++, we are able to create ActiveX controls and host them in a generic container. The container can read a menu system from a database and populate a tree and have an assigned GUID for the object to construct when each tree node is clicked. Can this phisophy be done in a Windows form .NET application (without ActiveX)? Can I construct a Form or a UserControl by simply reading in the form class name from a database table? I know I can create a builder class that could return a new object for a given piece of text, but that would mean I would have to update this builder class each time a new form were developed. I would like to create a container that never had to be modified...not sure if that is possible.

Absolutely, I would suggest you read through an article by Jason Clark on MSDN titled: Let Users Add Functionality to Your .NET Applications with Macros and Plug-Ins[^].

Thank you Nick! This is exactly what I needed. I had heard the Reflection term thrown around, but never realized what it was. Being a Visual C++ developer, this term means something very different to me. Thank you again. Smile | :)

One application with multiple forms

SebbaP1-Oct-04 5:01

What I am trying to do is to first start a form, which gives the user a choice between starting the application as a server or as a client. When the user has made this choice, the form should terminate. Now I wish to start another form, which provides another user interface. Like this:

static void Main()
{
ServerOrClientForm serverOrClient = new ServerOrClientForm();
Application.Run(serverOrClient);

serverOrClient.InputSelection();

UserInterface ui = new UserInterface();
Application.Run(ui);

// pass information to and from ui
obj = ui.GetInfo();
// ...
ui.SetInfo(obj);
}

The first form works well, but the other one (ui) does not show up at all. What am I doing wrong?

Brian Nottingham1-Oct-04 5:55

You are not doing anything wrong, this is a bug in the framework. When Application.Run finishes, a bit is set indicating that the message pump on the thread has shutdown. This bit is sticky, and any subsequent calls to Application.Run see this bit set and immediately terminate.

However, this should workaround your problem:

static void Main()
{
ServerOrClientForm serverOrClient = new ServerOrClientForm();
~~Application.Run(serverOrClient);~~
serverOrClient.ShowDialog();

serverOrClient.InputSelection();

UserInterface ui = new UserInterface();
Application.Run(ui);

// pass information to and from ui
obj = ui.GetInfo();
// ...
ui.SetInfo(obj);
}

Thank you very much for your reply! Regrettably, your solution does not work for me. It still behaves as it did before. I have changed the code into the following:

static void Main()
{
ServerOrClientForm serverOrClient = new ServerOrClientForm();
serverOrClient.ShowDialog();
serverOrClient.InputSelection();

System.Threading.Thread.Sleep(1000);

UserInterface ui = new UserInterface();
ui.ShowDialog();
}

I can clearly see the second form flashing by after the 1 second delay. The first form, however, works fine.

Brian Nottingham1-Oct-04 7:05

Please look at the code I had posted. For the "UserInterface" class, do not use ShowDialog(), but rather Application.Run(ui).

SebbaP1-Oct-04 7:50

I have tried that, and it did not work either. That's why I tried to use ShowDialog() on both of them.
