The situation occurs when two transactions exist in two sessions. Table: Tlock: Lock_id Tinyint Entry: 0 Steps to reconstruct the occurrence: 1. Open two client sessions of MySQL 2. In session 1, type "begin" followed by "update Tlock set Lock_id = 1". The sesssion shows the query "OK". 3. In session 2, type "begin" followed by "update Tlock set Lock_id = 2". The session waits for session 1 to release lock so nothing happens. 4. In session 1, type "update Tlock set Lock_id = 0". Session 2 warns a deadlock found. Why? If session 1 still holds the lock on Tlock, whatever it does to it shouldn't produce a deadlock. Can somebody explain what's actually happening behind the scene? Thank you very much!

Hi, I successfully send email with the following code in English. However, if the message and the subject title are in other characters, everything becomes question marks and the subject title says something like ...ANSI...3F=3F=3F... How do I set the character encoding to utf-8, for example? Thanks. try { Properties props = new Properties(); Session sendMailSession; Transport transport; sendMailSession = Session.getInstance(props, null); props.put("mail.smtp.host", SMTP_CLIENT); Message newMessage = new MimeMessage(sendMailSession); newMessage.setFrom(new InternetAddress(EMAIL_FROM)); newMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(strEmail)); newMessage.setSubject(SUBJECT); newMessage.setSentDate(new Date()); strMsg = "Dear " + RS.getString("FIRST") + " " + RS.getString("LAST") + ","; strMsg += "\n\n"; strMsg += [MESSAGE IN CHARACTERS OTHER THAN ASCII]; newMessage.setText(strMsg); transport = sendMailSession.getTransport("smtp"); transport.send(newMessage); } catch(MessagingException m) { ... }

Hi, my jsp page uses sun.net.smtp.SmtpClient to send email. It worked fine until the hosted location was moved to another server. Now it generates the sun.net.smtp.SmtpProtocolException and the hosting company can't find what's wrong with it so I'm here hoping somebody can help. What could cause the SmtpProtocolException? "locahost" was what I used to connect to the smtp server. When it failed, I tried another smtp server like "mail.xxx.com" on another server and it worked but the problem is that this server can't let me send mail to other domains except its own domain. Thanks The following is the code responsible for the email: ------------------------------------------------------------- try { client = new SmtpClient(localhost); client.from(EMAIL_FROM); client.to(strEmail); PrintStream message = client.startMessage(); message.println("From: " + EMAIL_FROM); message.println("To: " + strEmail); message.println("Subject: " + SUBJECT); message.println(); ... client.closeServer(); } catch(IOException e) {

That's one good technique but if it's used in a loop, the time it takes to load the image is certainly longer and the size it finds must be 0. How do I get around this?

I want to load all the images with the specific name and ended with a digit like image1.jpg, image2.jpg, image3.jpg, etc. The problem is that I wouldn't know in advance how many of them, so I just keep looping until I am told there is no more file.

The following code is supposed to submit the form to the process page. It works fine in IE, but not in Netvigator. When I hit the Submit, it just returns to the top and won't go. What should I add to make it work in Netvigator? function chkform() { var message = ""; /*if there is error in the form, append error string to the message*/ if(message.length > 0) { alert(message); return false; } else return true; } ... ... ...

I'm doing a Windows Paint-like application. I draw on the screen by capturing every mouse button-downs and moves, and then SetPixel(), the line drawn will be broken and I guess the Windows does not process the messages fast enough so some MouseMove do not react to every point the mouse moves. How does Windows Paint do that drawing on the screen without breaking? What should I do to smooth it?

Hi, veterans, I'm a student of C.S. I'm going to do a Windows program on drawing with MFC for my class project. Before I get into the real coding, I have to write a development plan to describe how I am going to do the project. I never made one before, and I have no any idea how to write a legitimate one. Please help, with some examples if any. Thanks very much.

Hi, veterans, how can I delete a character in CRichEditView?

Thanks, squizz, this is great.

Hi, all, I have problem doing a replacement of text in my text editor using CRichEditView class. I want to replace some text that the user types but have no idea what functions I can use. I am aware of the GetRichEditCtrl( ).Paste, which can paste a copied text at the position of the caret, but how do I insert a not clipboard stuff, such as a CString object. Peace, no war

Hi, all, I'm programming a text editor with spell check using MFC's CRichEditView class. Anybody knows how to move the caret? My usage is that when the user types a word that is found spelled wrong, the editor has to move its caret to the word's beginning position and replace the word. I'm new to Windows programming. I have no idea how to move the caret and replace the word. I tried typing SetCaretPos( ) and ShowCaret( ) in the CMainFrame derived from CFrameWnd, but it didn't actually move the caret. The caret seemed to change its postion to the one I set in SetCaretPos( ), but when I used GetRichEditCtrl( ).Paste to paste a text for a test, the text was pasted at the position as if I didn't do the SetCaretPos( ). Peace, no war
