Re: responding to keydown event while my form is inactive

2-Jan-04 9:22

Actually, this is conditional...

If you mean your entire application is not the active Window, then using a system hook is best.

If you mean that a dialog in your application has lot focus, but your application still has focus, then you should use an IMessageFilter and register it with Application.AddMessageFilter.

Using system hooks slows down the speed of the entire window manager because your program has to filter and process the necessary data. If you don't NEED to, don't do it.

Also, if you do use a system hook, make sure you unregister it before exiting your application, like in your main window's (i.e., the Form that was run with Application.Run) Close event handler, or better yet in the Dispose override, or before youe application's entry point (i.e., Main) exits.

Has someone print in .Net a custom papersize?. I have tried, and the only size that print is the standard size, 8.5" x 11". What do I need to do to change the papersize?

I don't know how to change it. But, was this not answered in the last 24 hours? Click "Search comments" above, i'm pretty sure your answer is there. Good Luck.

Do not keep posting the same question - we do not like that here and if you didn't get answers the first 1000 times, you probably won't get one at all (but might find more spam in your inbox!)
What I gave you should work (the link that Mazdak sent you). If it doesn't, you need to reply to that thread and - as I stated in the message - research the problem instead of just guessing and asking other people!

IntegraSoft2-Jan-04 9:25

2-Jan-04 9:25

Sorry. But I have research enough, and it is not in the .net help, it is, but it doesnt work. Your example and Mazdak'a didnt work also. Maybe you should try what you post. When I help someone in a problem, I tried to help them completly not half way. Thanks.

The examples in the MSDN documentation don't work? I hardly doubt that, because they have been tested and have been in public sight for several years now. I'm sure someone wouldn't noticed and alerted Microsoft, especially since they have such an easy documentation bug link at the bottom!

And as I have sound countless times - post WHY enumerating the PaperSizes didn't work! What exceptions where thrown, if any? It is possible that the printer does not support that paper size! It is, after all, a rather large piece of paper - if the printer tray doesn't support it, it will use the default!

So, write a simple application that enumerates and displays the valid PaperSizes that it supports and see, or debug your code and check the state of objects after lines that don't seem to have an effect.

If you keep asking the same question, you'll get the same answer - so provide us with more details and what exceptions - if any - are being thrown, or example snippets of code showing that you are trying what we have written and where the exception is being thrown. I assure you that enumerating PrinterSettings.PaperSizes works! Tell us why it's not working for you!

This is the example I am trying. I am using an Epson LX-300 printer. The enumeration worked, i forgot to tell you that. But my initial question was that I need to create a custom form, and print using that paper size. In this example, I created manually, in Server Properties, in the printer & faxes form, and created the "MIPAPEL" form. When selecting the papersize I use the last element in the enumeration, and it printed the size I wanted, but I created it manually. If I use the new PaperSize("CUSTOM", 8.5*100, 5.5*100) it doesnt work. It seems as it is ignoring my custom size. Also, when doing this, there are no exceptions.
Just create a C# project and copy this.

If you created a form called "MIPAPEL" (which I guess is supposed to be "MYPAPER"), why did you pass "CUSTOM" for the name of the form in the PaperSize constructor? Try passing "MYPAPER"/"MYPAPEL" and see if that works.

IntegraSoft2-Jan-04 10:18

2-Jan-04 10:18

I try that before sending the example and it doesnt work, The PaperSize only have one constructor, ant it ask for the name of the papaer, and the width, and height. I put the same thing and it ignores it. One of my problems is solved, because with the enumertion I could manually create the form and use it in my code. But what I need is to be able to create a new paper size, and use it. In the code I sent you, there was a mistake, the line that calls the querypagemethod take it out.

Thanks.

Look here: http://www.google.com/search?sourceid=navclient&ie=UTF-8&oe=UTF-8&q=PrintDocument+PaperSize+custom[^].

It does work. You could be right about the server forms configured on the system, but the PageSetupDialog doesn't seem to mind. If you solved the problem of printing an A3 form by enumerating the PaperSizes like I said a while back, great. If you're trying to print something else customized, it's possible the printer (or maybe even the print server) might not support it.

There were some examples of setting custom paper sizes in the google link I gave you. If they don't work for you, either you have a botched .NET installation (which I doubt, because many other things would be wrong), or your printer has problems or limitations. I have a Lexmark myself and I am not particular crazy about it (what can I say, it was free).

Have you tried a different printer?

IntegraSoft2-Jan-04 10:52

2-Jan-04 10:52

Thanks, I found what I was looking. But if you have read it, you have noticed that what I was asking cannot be done with C#, not completly. There is an example on how to add the form using c++ code, and then with that form, use it in c# to print the custom size. So I assume the custom size option using the papersize constructor only works on Windows 98 or before.

That's probably a safe assumption. Just P/Invoke the method(s) you need to save from having to write a native DLL.

Is there a way to turn on the standard context menu for a RichTextBox. (Copy/Cut/Paste/etc)

It shows up by default in a standard TextBox.

How to send mail using SMTP

2-Jan-04 9:15

There isn't one. It's not hard to provide, though - just create a ContextMenu with those menu items. The RichTextBox (inherited from TextBoxBase) already has methods for Cut, Copy, and Paste.

Please someone help me.

Um, do you know C#? If so, I can give you some refrences...

Framework SMTP Class:
System.Web.Mail Namespace[^]

CodeProject Examples:
SNTP Client in C#[^]
Sending Mail Using C# via SMTP[^]

But really; Before looking at all that, you should read this...

The SMTP Specification[^]

I havn't read this particular one, but I did read the POP3 specification. It gave me a much clearer understanding of what's going on. So, do that.

And always remember and never forget... SEARCH GOOGLE. There are tons of examples on the net too, with lots of 3rd party components also.

I hope this helps... I'm not sure if I under stood you correctly... "...without using any email client." With out a client at all, with out Outlook, a console window, service? i'm confused...

SmtpServer is where you post it TO,so it is obvios where does it go. Maybe these links helps you.

http://www.codeproject.com/csharp/emailsender.asp[^]

http://www.codeproject.com/dotnet/SMTP_with_Authentication.asp[^]

If you don't want any setting in your computer you can send mail with Socket class and do dot use SmtpMail class. Like this article:

You have to setup your SMTP Virtual Server in the Internet Information Manager snap-in (in your Administrative Tools in your Control Panel) to forward mail accordingly. Otherwise, the server doesn't know where to send mail.
