• Fogbugz search broken

  - by apollodude217

  The Search feature on our Fogbugz server is broken. It can look up case numbers just fine, but when I search for text, I get the following: FogBugz Internal Error An internal error occurred in FogBugz.

• Help Converting T-SQL Query to LINQ Query

  - by campbelt

  I am new to LINQ, and so am struggle over some queries that I'm sure are pretty simple. In any case, I have been hiting my head against this for a while, but I'm stumped. Can anyone here help me convert this T-SQL query into a LINQ query? Once I see how it is done, I'm sure I'll have some question about the syntax: SELECT BlogTitle FROM Blogs b JOIN BlogComments bc ON b.BlogID = bc.BlogID WHERE b.Deleted = 0 AND b.Draft = 0 AND b.[Default] = 0 AND bc.Deleted = 0 GROUP BY BlogTitle ORDER BY MAX([bc].[Timestamp]) DESC Just to show that I have tried to solve this on my own, here is what I've come up with so far, though it doesn't compile, let alone work ... var iqueryable = from blog in db.Blogs join blogComment in db.BlogComments on blog.BlogID equals blogComment.BlogID where blog.Deleted == false && blog.Draft == false && blog.Default == false && blogComment.Deleted == false group blogComment by blog.BlogID into blogGroup orderby blogGroup.Max(blogComment => blogComment.Timestamp) select blogGroup;

• Administrator's shortcut to batch file with double quoted parameters

  - by XXB

  Take an excruciatingly simple batch file: echo hi pause Save that as test.bat. Now, make a shortcut to test.bat. The shortcut runs the batch file, which prints "hi" and then waits for a keypress as expected. Now, add some argument to the target of the shortcut. Now you have a shortcut to: %path%\test.bat some args The shortcut runs the batch file as before. Now, run the shortcut as administrator. (This is on Windows 7 by the way.) You can use either right-click - Run as Administrator, or go to the shortcut's properties and check the box in the advanced section. Tell UAC that it's okay and once again the shortcut runs the batch file as expected. Now, change the arguments in the target of the shortcut to add double quotes: %path%\test.bat "some args" Now try the shortcut as administrator. It doesn't work this time! A command window pops up and and disappears too fast to see any error. I tried adding test.log 2&1 to the shortcut, but no log is created in this case. Try running the same shortcut (with the double quotes) but not as Administrator. It runs the batch file fine. So, it seems the behavior is not because of the double quoted parameters, and it's not because it's run as Administrator. It's some weird combination of the two. I also tried running the same command from an administrator's command window. This ran the batch file as expected without error. Running the shortcut from the command window spawned a new command window which flashed and went away. So apparently the issue is caused by a combination of administrator, the shortcut, and the double quotes. I'm totally stumped, does anyone have any idea what's going on?

• Prevent Jquery Accordion tab from expanding

  - by Edwin

  I'm trying to use JQuery UI Accordion as a menu, but I can't figure out how to prevent some tabs from expanding. My JS: $("#sidebar").accordion({ collapsible: true, changestart: function(event, ui) { switch ($(ui.newHeader).attr("id")) { case "sidebar_grades": return false; break; } } }); the HTML: <div id="sidebar"> <h3 id="sidebar_home"> <a href="/blah">Home</a> </h3> <div> <a href="/child">Settings</a> </div> <h3 id="sidebar_grades"> <a href="/grades">Grades</a> </h3> <div></div> <h3 id="sidebar_calendar"> <a href="/calendar">Calendar</a> </h3> <div></div> </div> In the above example, since #sidebar_grades doesn't have any child, it should not be expandable, but user can click on the link. I tried using "changestart" event and return false when #sidebar_grades is clicked, but it doesn't work. I also tried attaching onClick event to #sidebar_grades to return false, but that didn't work either. Any idea how to do this? Thank you!

• setAnimationRepeatAutoreverses not behaved as I expected

  - by danielkwan

  I am starting to learn to use UIView animation. So I wrote the following lines: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2.0]; [UIView setAnimationRepeatCount:2]; [UIView setAnimationRepeatAutoreverses:YES]; CGPoint position = greenView.center; position.y = position.y + 100.0f; position.x = position.x + 100.0f; greenView.center = position; [UIView commitAnimations]; In this case, the UIView (a green box) moved back and fore 2 times. So far so good, BUT I found out that after the moving twice, the green box ended up jumped to the "new position" (position.x + 100.0f, position.y + 100.0f) instead of going back to the original position (position.x, position.y). That makes the animation look pretty odd (like after the box swing back to the original position caused by setAnimationRepeatAutoreverses, it jumps back to the new position in the last microsecond!) What is the best way to make the green box NOT jump to the new position at the very last minute?

• Problem with dynamic create tabPages in Winforms TabControl

  - by mirt

  I want to create dynamic tabPages in TabControl. In each tabPage I create dataGridView and i want to fill the entire space of each tabPage with this dataGrid. Here is code, where i do this: private void tabControlMutants_SelectedIndexChanged(object sender, EventArgs e) { DataGridView dgw = new DataGridView(); DataGridViewTextBoxColumn testCaseCol = new System.Windows.Forms.DataGridViewTextBoxColumn(); DataGridViewTextBoxColumn resultCol = new System.Windoows.Forms.DataGridViewTextBoxColumn(); // // dataGridView1 // dgw.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize; dgw.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] { testCaseCol, resultCol}); dgw.Location = new System.Drawing.Point(3, 3); dgw.Name = "dataGridView1"; dgw.AutoSize = true; dgw.Dock = System.Windows.Forms.DockStyle.Fill; dgw.TabIndex = 0; // // TestCaseColumn // testCaseCol.AutoSizeMode = System.Windows.Forms.DataGridViewAutoSizeColumnMode.Fill; testCaseCol.HeaderText = "Test Case"; testCaseCol.Name = "TestCaseColumn"; // // ResultColumn // resultCol.HeaderText = "Result"; resultCol.Name = "ResultColumn"; tabControlMutants.TabPages[(sender as TabControl).SelectedIndex].Controls.Add(dgw); ((System.ComponentModel.ISupportInitialize)(dgw)).EndInit(); //fill dataGridView } But it doesn't work, becouse when i resize the main window, data gridView doesn.t change its size (although the dock property is set to fill). Any ideas?

• When does a PHP <5.3.0 daemon script receive signals?

  - by MidnightLightning

  I've got a PHP script in the works that is a job worker; its main task is to check a database table for new jobs, and if there are any, to act on them. But jobs will be coming in in bursts, with long gaps in between, so I devised a sleep cycle like: while(true) { if ($jobs = get_new_jobs()) { // Act upon the jobs } else { // No new jobs now sleep(30); } } Good, but in some cases that means there might be a 30 second lag before a new job is acted upon. Since this is a daemon script, I figured I'd try the pcntl_signal hook to catch a SIGUSR1 signal to nudge the script to wake up, like: $_isAwake = true; function user_sig($signo) { global $_isAwake; daemon_log("Caught SIGUSR1"); $_isAwake = true; } pcntl_signal(SIGUSR1, 'user_sig'); while(true) { if ($jobs = get_new_jobs()) { // Act upon the jobs } else { // No new jobs now daemon_log("No new jobs, sleeping..."); $_isAwake = false; $ts = time(); while(time() < $ts+30) { sleep(1); if ($_isAwake) break; // Did a signal happen while we were sleeping? If so, stop sleeping } $_isAwake = true; } } I broke the sleep(30) up into smaller sleep bits, in case a signal doesn't interrupt a sleep() command, thinking that this would cause at most a one-second delay, but in the log file, I'm seeing that the SIGUSR1 isn't being caught until after the full 30 seconds has passed (and maybe the outer while loop resets). I found the pcntl_signal_dispatch command, but that's only for PHP 5.3 and higher. If I were using that version, I could stick a call to that command before the if ($_isAwake) call, but as it currently stands I'm on 5.2.13. On what sort of situations is the signals queue interpreted in PHP versions without the means to explicitly call the queue parsing? Could I put in some other useless command in that sleep loop that would trigger a signal queue parse within there?

• Mixing NIO with IO

  - by Steffen Heil

  Hi Usually you have a single bound tcp port and several connections on these. At least there are usually more connections as bound ports. My case is different: I want to bind a lot of ports and usually have no (or at least very few) connections. So I want to use NIO to accept the incoming connections. However, I need to pass the accepted connections to the existing jsch ssh library. That requires IO sockets instead of NIO sockets, it spawns one (or two) thread(s) per connection. But that's fine for me. Now, I thought that the following lines would deliver the very same result: Socket a = serverSocketChannel.accept().socket(); Socket b = serverSocketChannel.socket().accep(); SocketChannel channel = serverSocketChannel.accpet(); channel.configureBlocking( true ); Socket c = channel.socket(); Socket d = serverSocket.accept(); However the getInputStream() and getOutputStream() functions of the returned sockets seem to work different. Only if the socket was accepted using the last call, jsch can work with it. In the first three cases, it fails (and I am sorry: I don't know why). So is there a way to convert such a socket? Regards, Steffen

• Strange UIKit bug, table view row stays selected

  - by Can Berk Güder

  I'm facing what appears to be a UIKit bug, and it takes the combination of two less commonly used features to reproduce it, so please bear with me here. I have quite the common view hierarchy: UITabBarController -> UINavigationController -> UITableViewController and the table view controller pushes another table view controller onto the navigation controller's stack when a row is selected. There's absolutely nothing special or fancy in the code here. However, the second UITableViewController, the "detail view controller" if you will, does two things: It sets hidesBottomBarWhenPushed to YES in its init method, so the tab bar is hidden when this controller is pushed: - (id)initWithStyle:(UITableViewStyle)style { if(self = [super initWithStyle:style]) { self.hidesBottomBarWhenPushed = YES; } return self; } It calls setToolbarHidden:NO animated:YES and setToolbarHidden:YES animated:YES on self.navigationController in viewWillAppear: and viewWillDisappear: respectively, causing the UIToolbar provided by UINavigationController to be displayed and hidden with animations: - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self.navigationController setToolbarHidden:NO animated:YES]; } - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [self.navigationController setToolbarHidden:YES animated:YES]; } Now, if the second UITableViewController was pushed by selecting the row at the bottom of the screen (it doesn't have to be the last row) in the first controller, this row does not automatically get deselected when the user immediately or eventually returns to the first controller. Further, the row cannot be deselected by calling deselectRowAtIndexPath:animated: on self.tableView in viewWillAppear: or viewDidAppear: in the first controller. I'm guessing this is a bug in UITableViewController's drawing code which of course only draws visible rows, but unfortunately fails to determine correctly if the bottommost row will be visible in this case. I failed to find anything on this on Google or OpenRadar, and was wondering if anyone else on SO had this problem or knew a solution/workaround.

• Large number of simultaneous long-running operations in Qt

  - by Hostile Fork

  I have some long-running operations that number in the hundreds. At the moment they are each on their own thread. My main goal in using threads is not to speed these operations up. The more important thing in this case is that they appear to run simultaneously. I'm aware of cooperative multitasking and fibers. However, I'm trying to avoid anything that would require touching the code in the operations, e.g. peppering them with things like yieldToScheduler(). I also don't want to prescribe that these routines be stylized to be coded to emit queues of bite-sized task items...I want to treat them as black boxes. For the moment I can live with these downsides: Maximum # of threads tend to be O(1000) Cost per thread is O(1MB) To address the bad cache performance due to context-switches, I did have the idea of a timer which would juggle the priorities such that only idealThreadCount() threads were ever at Normal priority, with all the rest set to Idle. This would let me widen the timeslices, which would mean fewer context switches and still be okay for my purposes. Question #1: Is that a good idea at all? One certain downside is it won't work on Linux (docs say no QThread::setPriority() there). Question #2: Any other ideas or approaches? Is QtConcurrent thinking about this scenario? (Some related reading: how-many-threads-does-it-take-to-make-them-a-bad-choice, many-threads-or-as-few-threads-as-possible, maximum-number-of-threads-per-process-in-linux)

• Custom Keyboard (iPhone), UIKeyboardDidShowNotification and UITableViewController

  - by Pascal

  On an iPhone App, I've got a custom keyboard which works like the standard keyboard; it appears if a custom textfield becomes first responder and hides if the field resigns first responder. I'm also posting the Generic UIKeyboardWillShowNotification, UIKeyboardDidShowNotification and their hiding counterparts, like follows: NSMutableDictionary *userInfo = [NSMutableDictionary dictionaryWithCapacity:5]; [userInfo setObject:[NSValue valueWithCGPoint:self.center] forKey:UIKeyboardCenterBeginUserInfoKey]; [userInfo setObject:[NSValue valueWithCGPoint:shownCenter] forKey:UIKeyboardCenterEndUserInfoKey]; [userInfo setObject:[NSValue valueWithCGRect:self.bounds] forKey:UIKeyboardBoundsUserInfoKey]; [userInfo setObject:[NSNumber numberWithInt:UIViewAnimationCurveEaseOut] forKey:UIKeyboardAnimationCurveUserInfoKey]; [userInfo setObject:[NSNumber numberWithDouble:thisAnimDuration] forKey:UIKeyboardAnimationDurationUserInfoKey]; [[NSNotificationCenter defaultCenter] postNotificationName:UIKeyboardWillShowNotification object:nil userInfo:userInfo]; This code is working and I use it in UIViewController subclasses. Now since iPhone OS 3.0, UITableViewController automatically resizes its tableView when the system keyboards show and hide. I'm only now compiling against 3.0 and I thought that the controller should also resize the table if my custom keyboard appears, since I'm posting the same notification. However it doesn't. The table view controller is set as the delegate of the input fields. Does anyone have an idea why this might be the case? Has anyone implemented something similar successfully? I have standard input fields along the custom ones, so if the user changes the fields the standard keyboard hides and the custom one shows. It would be beneficial if the tableView didn't resize to full height and I didn't have to resize it back with a custom method.

• T-SQL Right Joins to ALL Entries inc Selected Column

  - by Pace

  Hi Experts, I have the following Query which produces the output below; SELECT TBLUSERS.USERID, TBLUSERS.ADusername, TBLACCESSLEVELS.ACCESSLEVELID, TBLACCESSLEVELS.AccessLevelName FROM TBLACCESSLEVELS INNER JOIN TBLACCESSRIGHTS ON TBLACCESSLEVELS.ACCESSLEVELID = TBLACCESSRIGHTS.ACCESSLEVELID INNER JOIN TBLUSERS ON TBLACCESSRIGHTS.USERID = TBLUSERS.USERID The output is this; 29 administrator 1 AllUsers 29 administrator 2 JobQueue 29 administrator 3 Telephone Directory Admin 29 administrator 4 Jobqueueadmin 29 administrator 5 UserAdmin 29 administrator 6 Product System 27 alan 1 AllUsers 97 andy 1 AllUsers 26 barry 1 AllUsers 26 barry 2 JobQueue 26 barry 3 Telephone Directory Admin 26 barry 4 Jobqueueadmin 26 barry 5 UserAdmin 26 barry 6 Product System 26 barry 7 Newseditor 26 barry 8 GreetingBoard What I would like to do is modify the query so I get all Access Levels regardless of weather there is an entry for that user. What I would also like to do is some sort of exist case so that I get output like the following; 29 administrator 1 AllUsers True 29 administrator 2 JobQueue True 29 administrator 3 Telephone Directory Admin True 29 administrator 4 Jobqueueadmin True 29 administrator 5 UserAdmin True 29 administrator 6 Product System True 29 administrator 7 Newseditor False 29 administrator 8 GreetingBoard False 27 alan 1 AllUsers True 27 alan 2 JobQueue False 27 alan 3 Telephone Directory Admin False 27 alan 4 Jobqueueadmin False 27 alan 5 UserAdmin False 27 alan 6 Product System False 27 alan 7 Newseditor False 27 alan 8 GreetingBoard False 97 andy 1 AllUsers True 97 andy 2 JobQueue False 97 andy 3 Telephone Directory Admin False 97 andy 4 Jobqueueadmin False 97 andy 5 UserAdmin False 97 andy 6 Product System False 97 andy 7 Newseditor False 97 andy 8 GreetingBoard False 26 Barry 1 AllUsers True 26 Barry 2 JobQueue True 26 Barry 3 Telephone Directory Admin True 26 Barry 4 Jobqueueadmin True 26 Barry 5 UserAdmin True 26 Barry 6 Product System True 26 Barry 7 Newseditor True 26 Barry 8 GreetingBoard True ......................................... So the rules are ALWAYS show ALL Entries for ACCESSLEVELS and where EXISTS in ACCESSRIGHTS produce a true / false to show this. I hope this makes sense and hopefully you dont need the table definitions as everything I need to work with is in the original Query. I just need a way of manipulating it slightly and getting the join in the right place. Thank you. Pace

• Indy Write Buffering / Efficient TCP communication

  - by Smasher

  I know, I'm asking a lot of questions...but as a new delphi developer I keep falling over all these questions :) This one deals with TCP communication using indy 10. To make communication efficient, I code a client operation request as a single byte (in most scenarios followed by other data bytes of course, but in this case only one single byte). Problem is that var Bytes : TBytes; ... SetLength (Bytes, 1); Bytes [0] := OpCode; FConnection.IOHandler.Write (Bytes, 1); ErrorCode := Connection.IOHandler.ReadByte; does not send that byte immediately (at least the servers execute handler is not invoked). If I change the '1' to a '9' for example everything works fine. I assumed that Indy buffers the outgoing bytes and tried to disable write buffering with FConnection.IOHandler.WriteBufferClose; but it did not help. How can I send a single byte and make sure that it is immediatly sent? And - I add another little question here - what is the best way to send an integer using indy? Unfortunately I can't find function like WriteInteger in the IOHandler of TIdTCPServer...and WriteLn (IntToStr (SomeIntVal)) seems not very efficient to me. Does it make a difference whether I use multiple write commands in a row or pack things together in a byte array and send that once? Thanks for any answers! EDIT: I added a hint that I'm using Indy 10 since there seem to be major changes concerning the read and write procedures.

• Using Unit Tests While Developing Static Libraries in Obj-C

  - by macinjosh

  I'm developing a static library in Obj-C for a CocoaTouch project. I've added unit testing to my Xcode project by using the built in OCUnit framework. I can run tests successfully upon building the project and everything looks good. However I'm a little confused about something. Part of what the static library does is to connect to a URL and download the resource there. I constructed a test case that invokes the method that creates a connection and ensures the connection is successful. However when my tests run a connection is never made to my testing web server (where the connection is set to go). It seems my code is not actually being ran when the tests happen? Also, I am doing some NSLog calls in the unit tests and the code they run, but I never see those. I'm new to unit testing so I'm obviously not fully grasping what is going on here. Can anyone help me out here? P.S. By the way these are "Logical Tests" as Apple calls them so they are not linked against the library, instead the implementation files are included in the testing target.

• How can parallelism affect number of results?

  - by spender

  I have a fairly complex query that looks something like this: create table Items(SomeOtherTableID int,SomeField int) create table SomeOtherTable(Id int,GroupID int) with cte1 as ( select SomeOtherTableID,COUNT(*) SubItemCount from Items t where t.SomeField is not null group by SomeOtherTableID ),cte2 as ( select tc.SomeOtherTableID,ROW_NUMBER() over (partition by a.GroupID order by tc.SubItemCount desc) SubItemRank from Items t inner join SomeOtherTable a on a.Id=t.SomeOtherTableID inner join cte1 tc on tc.SomeOtherTableID=t.SomeOtherTableID where t.SomeField is not null ),cte3 as ( select SomeOtherTableID from cte2 where SubItemRank=1 ) select * from cte3 t1 inner join cte3 t2 on t1.SomeOtherTableID<t2.SomeOtherTableID option (maxdop 1) The query is such that cte3 is filled with 6222 distinct results. In the final select, I am performing a cross join on cte3 with itself, (so that I can compare every value in the table with every other value in the table at a later point). Notice the final line : option (maxdop 1) Apparently, this switches off parallelism. So, with 6222 results rows in cte3, I would expect (6222*6221)/2, or 19353531 results in the subsequent cross joining select, and with the final maxdop line in place, that is indeed the case. However, when I remove the maxdop line, the number of results jumps to 19380454. I have 4 cores on my dev box. WTF? Can anyone explain why this is? Do I need to reconsider previous queries that cross join in this way?

• help in the Donalds B. Johnson's algorithm, i cannot understand the pseudo code

  - by Pitelk

  Hi , does anyone know the Donald B. Johnson's algorithm which enumarates all the elementary circuits (cycles) in a Directed graph? link text I have the paper he had published in 1975 but I cannot understand the pseudo-code. My goal is to implement this algorithm in java. Some questions i have is for example what is the matrix Ak it refers to. In the pseudo code mentions that Ak:=adjacency structure of strong component K with least vertex in subgraph of G induced by {s,s+1,....n}; Does that mean i have to implement another algorithm that finds the Ak matrix? Another question is what the following means? begin logical f; Does also the line "logical procedure CIRCUIT (integer value v);" means that the circuit procedure returns a logical variable. In the pseudo code also has the line "CIRCUIT := f;" . Does this mean? It would be great if someone could translate this 1970's pseudocode to a more modern type of pseudo code so i can understand it in case you are interested to help but you cannot find the paper please email me at [email protected] and i will send you the paper. Thanks in advance

• How to separate ear classloader and system classloader in JBoss 6?

  - by dskiles

  I'm trying to upgrade from JBoss 4.2.1 to JBoss 6. In JBoss 4.2.1, we are manually deploying our application as an exploded war and everything works beautifully. I'm running into problems because the application that I am trying to deploy uses versions of 3rd party libraries that are older than the ones that JBoss 6 now includes by default. The result of this is that I'm getting classloader conflicts all over the place and the application won't even start. At present, I have tried using the JBoss Classloading Documentation as well as the scanty bits of documentation for jboss-classloading.xml and haven't had any success. Has anyone out there managed to do this successfully? If you have, how did you do it? I've included a stack trace below in case it offers any useful information.

• Handling mach exceptions in 64bit OS X application

  - by Brad S

  I have been able to register my own mach port to capture mach exceptions in my applications and it works beautifully when I target 32 bit. However when I target 64 bit, my exception handler catch_exception_raise() gets called but the array of exception codes that is passed to the handler are 32 bits wide. This is expected in a 32 bit build but not in 64 bit. In the case where I catch EXC_BAD_ACCESS the first code is the error number and the second code should be the address of the fault. Since the second code is 32 bits wide the high 32 bits of the 64 bit fault address is truncated. I found a flag in <mach/exception_types.h> I can pass in task_set_exception_ports() called MACH_EXCEPTION_CODES which from looking at the Darwin sources appears to control the size of the codes passed to the handler. It looks like it is meant to be ored with the behavior passed in to task_set_exception_ports(). However when I do this and trigger an exception, my mach port gets notified, I call exc_server() but my handler never gets called, and when the reply message is sent back to the kernel I get the default exception behavior. I am targeting the 10.6 SDK. I really wish apple would document this stuff better. Any one have any ideas?

• Could CouchDB benefit significantly from the use of BERT instead of JSON?

  - by Victor Rodrigues

  I appreciate a lot CouchDB attempt to use universal web formats in everything it does: RESTFUL HTTP methods in every interaction, JSON objects, javascript code to customize database and documents. CouchDB seems to scale pretty well, but the individual cost to make a request usually makes 'relational' people afraid of. Many small business applications should deal with only one machine and that's all. In this case the scalability talk doesn't say too much, we need more performance per request, or people will not use it. BERT (Binary ERlang Term http://bert-rpc.org/ ) has proven to be a faster and lighter format than JSON and it is native for Erlang, the language in which CouchDB is written. Could we benefit from that, using BERT documents instead of JSON ones? I'm not saying just for retrieving in views, but for everything CouchDB does, including syncing. And, as a consequence of it, use Erlang functions instead of javascript ones. This would modify some original CouchDB principles, because today it is very web oriented. Considering I imagine few people would make their database API public and usually its data is accessed by the users through an application, it would be a good deal to have the ability to configure CouchDB for working faster. HTTP+JSON calls could still be handled by CouchDB, considering an extra cost in these cases because of parsing.

• overriding enumeration base type using pragma or code change

  - by vprajan

  Problem: I am using a big C/C++ code base which works on gcc & visual studio compilers where enum base type is by default 32-bit(integer type). This code also has lots of inline + embedded assembly which treats enum as integer type and enum data is used as 32-bit flags in many cases. When compiled this code with realview ARM RVCT 2.2 compiler, we started getting many issues since realview compiler decides enum base type automatically based on the value an enum is set to. http://www.keil.com/support/man/docs/armccref/armccref_Babjddhe.htm For example, Consider the below enum, enum Scale { TimesOne, //0 TimesTwo, //1 TimesFour, //2 TimesEight, //3 }; This enum is used as a 32-bit flag. but compiler optimizes it to unsigned char type for this enum. Using --enum_is_int compiler option is not a good solution for our case, since it converts all the enum's to 32-bit which will break interaction with any external code compiled without --enum_is_int. This is warning i found in RVCT compilers & Library guide, The --enum_is_int option is not recommended for general use and is not required for ISO-compatible source. Code compiled with this option is not compliant with the ABI for the ARM Architecture (base standard) [BSABI], and incorrect use might result in a failure at runtime. This option is not supported by the C++ libraries. Question How to convert all enum's base type (by hand-coded changes) to use 32-bit without affecting value ordering? enum Scale { TimesOne=0x00000000, TimesTwo, // 0x00000001 TimesFour, // 0x00000002 TimesEight, //0x00000003 }; I tried the above change. But compiler optimizes this also for our bad luck. :( There is some syntax in .NET like enum Scale: int Is this a ISO C++ standard and ARM compiler lacks it? There is no #pragma to control this enum in ARM RVCT 2.2 compiler. Is there any hidden pragma available ?

• Broken tables in RichTextBox control (word wrap)

  - by Ben Robbins

  We are having problems with the Windows.Forms.RichTextBox control in Visual Studio 2008. We are trying to display text supplied as an RTF file by a 3rd party in a windows forms application (.NET 3.5). In this RTF text file there are tables, which contain text that spans multiple lines. The RTF file displays correctly when opened with either WordPad or Word 2003. However, when we load the RTF file into the RichTextBox control, or copy & paste the whole text (including the table) into the control, the table does not display correctly - the cells are only single line, without wrapping. Here are links to images showing the exact problem: Correctly displayed in WordPad Incorrectly displayed in RichTextBox control I have googled for solutions and 3rd party .net RTF controls without success. I have found this exact problem asked on another forum without an answer (in fact that's where the link to the images come from) so I'm hoping stack overflow does better ;-) My preferred solution would be to use code or a 3rd party control that can correctly render the RTF. However, I suspect the problem is that the RichTextBox control only supports a subset of the full RTF spec, so another option would be to modify the RTF directly to remove the unsupported control codes or otherwise fix the RTF file itself (in which case any information as to what control codes need to be removed or modified would be a huge help).

• Android:Multi touch doesn't work as expected?

  - by user187532

  Hi folks, Help me in resolving the below issue. I have three image buttons on screen. All these three buttons controlled under ontouchlistner as below. buttonOne.setOnTouchListener(this); buttonTwo.setOnTouchListener(this); buttonThree.setOnTouchListener(this); I override "public boolean onTouch(View v, MotionEvent event)". Under this i check for these three image buttons touch events like below. ImageButton imageBtn = (ImageButton) v; if ( imageBtn == buttonOne ) // first button touch ..Log.. else if ( imageBtn == buttonTwo ) ..Log.. else if ( imageBtn == buttonThree ) // first button touch ..Log.. My problem is, as it is under multi touch event handler like above, it does not detect when touch all three button at a time to try to produce multi touch effect, instead it detects only one imagebutton touch at a time even though i touch all three image buttons. As i am developing this project on Android 1.6 SDK, is there any problem accessing my requirement(multi touch) (or) it is a known issue? I am hoping that, when it works for single button touch, why shouldn't it work when clicking three imagebuttons at a time to produce three logs printed as per my above code? How do i resolve it for my case? Please don't question me why i am still developing on 1.6 for such a requirement. Thank you. Appreciate your suggestions !
