  • MySQL 5.1 - logging CREATE/ALTER statements

    - by pako
    Is it possible to log CREATE / ALTER statements issued on a MySQL server? I heard that it could be done with a trigger, but I can't seem to find suitable code anywhere. I would like to log these statements to a table, preferably with the timestamp of when they were issued. Can someone provide me with a sample trigger that would enable me to accomplish this? I would like to log these statements so I can easily synchronize the changes with another MySQL server.

  • Find Rank in Microsoft Report

    - by Alex Essilfie
    Is there any way I can find the rank of a set of values in Microsoft Reports? For instance, in order to produce a table like the one below, what function/formula do I enter in the Rank column? +------+-----+ |Value | Rank| +------+-----+ | 12 | 3 | | 30 | 5 | | 5 | 1 | | 10 | 2 | | 24 | 4 | +------+-----+ Update Values in the value column are produced from calculations on the report-side so I cannot find the rank using a query.

  • Images inside of UILabel

    - by enby
    hello everyone! I'm trying to find the best way to display images inside of UILabels (in fact, I wouldn't mind switching to something other than UILabel if it supports images with no hassle) The scenario is: I have a table view with hundreds of cells and UILabel being the main component of each cell The text I assign to each cell contains sequences of characters that need to be parsed out and represented as an image In simpler words, imagine a TableView of an instant messenger that parses replaces all ":)", ":(", ":D" etc with corresponding smiley images Any input would be greatly appreciated!

  • UITableView: Mixing static and dynamic cells

    - by AlexR
    I am trying to mix dynamic and static cells in a grouped table view: I would like to get two sections with static cells at the top followed by a section of dynamic cells (please refer to the screenshot below). I have set the table view contents to static cells. I designed the static cells in Interface Builder and gave them identifiers related to their section and row: "section0static0", "section0static1", "section1static0" and "section1static1". I named the dynamic cell "section2dynamic". My delegate methods, in which I am trying to return the correct cell identifier (static or dynamic) are as follows: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { switch (section) { case 0: return 2; break; case 1: return 2; break; case 2: return 0; break; default: break; } return 0; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @""; if (indexPath.section <= 1) CellIdentifier = [NSString stringWithFormat:@"section%istatic%i",indexPath.section,indexPath.row]; else CellIdentifier = [NSString stringWithFormat:@"section%idynamic",indexPath.section]; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; return cell; } Edit Based on AppleFreak's advice I have changed my code as follows: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell; if (indexPath.section <= 1) { // section <= 1 indicates static cells cell = [super tableView:tableView cellForRowAtIndexPath:indexPath]; } else { // section > 1 indicates dynamic cells CellIdentifier = [NSString stringWithFormat:@"section%idynamic",indexPath.section]; cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; } return cell; } However, my app crashes with error message Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:' for section 0 and row 0. The cell returned from cell = [super tableView:tableView cellForRowAtIndexPath:indexPath] for section 0 and row 0 is nil. What is wrong with my code? Could there be any problems with my outlets? I haven't set any outlets because I am subclassing UITableViewController and supposedly do not any outlets for tableview to be set (?). Any suggestions on how to better do it?

  • Paste a multi-line Java String in Eclipse

    - by Thilo
    Unfortunately, Java has no syntax for multi-line string literals. No problem if the IDE makes it easy to work with constructs like String x = "CREATE TABLE TEST ( \n" + "A INTEGER NOT NULL PRIMARY KEY, \n" ... What is the fastest way to paste a multi-line String from the clipboard into Java source using Eclipse (in a way that it automagically creates code like the above).
