  • Strange Exception on getGeneratedKeys() with JDBC for MySQL 5.1

    - by sweeney
    Hello, I'm using JDBC to insert a row into a MYSQL database. I build a parameterized command, execute it and attempt to retrieve the auto generated keys as follows: String sql = "INSERT IGNORE INTO `users` (`email`, `pass-hash`) VALUES (?, ?)"; Connection conn = SQLAccess.getConnection(); PreparedStatement ps = conn.prepareStatement(sql); ps.setString(1, login); ps.setString(2, passHash); int count = ps.executeUpdate(); if (count == 1) { ResultSet rs = ps.getGeneratedKeys(); rs.next(); //some more stuff... } For some reason, I get the following SQLException on the line containing ResultSet rs = ps.getGeneratedKeys();: !Statement.Generated Keys Not Requested! Any thoughts? When I run the same query, as generated by running the app through the debugger, in a MySQL browser it executes without incident. Thanks, brian

  • EAGLView orientation changes and strange buffering

    - by Drew
    I'm writing an app that offloads some heavy drawing into an EAGLView, and it does some lightweight stuff in UIKit on top. It seems that the GL render during an orientation change is cached somewhere, and I can't figure out how to get access to it. Specifically: After an orientation change, calling glClear(GL_COLOR_BUFFER_BIT) isn't enough to clear the GL display (drawing is cached somewhere?) How can I clear this cache? After an orientation change, glReadPixel() can no longer access pixels drawn before the orientation change. How can I get access to where this is stored?

  • Synergy on Linux and Linux

    - by archer
    Using Synergy-plus-1.3.4 on Gentoo Linux kernel 2.6.36-tuxonice-r3. Using SHIFT+CAPS to change keyboard layout on BOTH server and client boxes. Works perfectly if change layout using attached keyboard. But when using synergy keyboard (moved mouse from server screen to client and changing with SHIFT+CAPS) it has no effect. Synergy is just amazing thing exception this small issue which I'm assured is solvable. Please, gimme some hint.

  • Tree item edit event listener in flex

    - by Biroka
    I want to catch itemEditEnd in a tree control, but i'm having a little trouble. I call the item editing a bit different: <mx:Tree id="tree" width="100%" height="100%" itemDoubleClick="treeProjects_itemDoubleClickHandler(event)" doubleClickEnabled="true" editable="true" itemEditBeginning="treeProjects_itemEditBeginingHandler(event)" itemEditEnd="treeProjects_itemEditEndHandler(event)" > but: protected function treeProjects_itemEditBeginingHandler(event:ListEvent):void { event.preventDefault(); } i do this, because I want to edit the field just when clicking rename in the context menu. And when I click rename in the context menu, this is what i'm doing (contextParentItem is the event catched on itemRollOver in the tree) : Tree( contextParentItem.target ).editedItemPosition = { columnIndex: 0, rowIndex: contextParentItem.rowIndex }; Thisway I can't catch the itemEditEnd event, but I want to handle some stuff, like: if the new entered value is an empty string, then I don't want to accept the new value if I hit ESC then, the old value should remain.

  • Index a set of files to search their text quickly?

    - by Ricket
    I have a unique need: I am frequently searching a large set of text files for a keyword. Right now, I open up Notepad++ and use the "Find in files" feature. It works just fine, but with the amount of files, each search takes several minutes to complete. Is there a good program more suited for this purpose, perhaps that indexes a set of files and then lets you search the set repeatedly and very quickly? It would greatly speed up my workflow.

  • How do I edit an interface builder object programmatically?

    - by Evelyn
    I created a label using Interface Builder, and now I want to set the background color of the label using code instead of IB's color picker. (I want to do this so that I can define the color using RGB and eventually change the colorspace for the label.) I'm in cocoa. How do I edit the attributes of an IB object using code? My code looks like this: //.h file #import <UIKit/UIKit.h> @interface IBAppDelegate : NSObject { UILabel *label; } @property (nonatomic, retain) IBOutlet UILabel *label; @end //.m file #import "IBAppDelegate.h" @implementation IBAppDelegate @synthesize label; (memory stuff...) @end

  • Debug JS from browser without a server/localhost

    - by sazpaz
    So something I do very frequently is writing random scripts in JS without really being part of an app. To run them I just paste them in the console of either Chrome of FF which works as a nice REPL, or if I really need more fancy debugging I just add it to my test app on localhost and browse it from the browser. Is there a way to get all the good debugging of a browser (breakpoints, locals, etc), without it being served from a server?, e.g by just copy-pasting my code into console or something?

  • NFS Server in Java

    - by dmeister
    I search an implementation of a network (or distributed) file system like NFS in Java. The goal is to extend it and do some research stuff with it. On the web I found some implementation e.g. DJ NFS, but the open question is how mature and fast they are. Can anyone purpose a good starting point, has anyone experience with such things? P.S. I know Hadoop DFS and I used it for some projects, but Hadoop is not a good fit for the things I want to do here. --EDIT-- Hadoop is really focused on highly scalable, high throughput computing without the possibilities to overwrite parts of a file and so an. The goal is you could use the filesystem e.g. for user home directories. --EDIT-- More Details: The idea is to modify such a implementation so that the files are not stored directly on a local filesystem, but to apply data de-duplication.

  • keepass not working with wine

    - by Decio Lira
    I installed Keepass 1.16 in my thumbdrive, which reportedly works with wine (as per Keepass homepage), but after entering the master password it just hangs and shows the "The program keepass has encountered a serious problem and needs to close" screen. I got this error msg among the stack trace on the terminal: wine: Call from 0x7b844633 to unimplemented function bcrypt.dll.BCryptOpenAlgorithmProvider, aborting On windows, everything runs fine. I'm using wine-1.1.27 on ubuntu 9.04 Any thoughts?

  • window.opener.document.getElementById not working

    - by Curtis
    In my asp.net web app, I create a popup window with a button. When that button is clicked, I want to set the value of an asp:TextBox (id=TextBox1) contained in the parent window. However, it doesn't work like all the examples I've read indicate. I've tried the following lines of code in my javascript onclick handler: window.opener.document.getElementById('<%= TextBox1.ClientID %').value = "abc"; window.opener.document.getElementById("TextBox1").value = "abc"; window.opener.document.getElementById("ctl00_ContentPlaceHolder1_TextBox1").value = "abc"; Only example 3 works. All the stuff I've read indicates that #1 is the preferred method, but I can't seem to make it work at all. Does anyone have any ideas what I'm doing wrong? I've tried this in Firefox, Chrome and IE. Thanks

  • recv returns old data

    - by anon
    This loop is supposed to take data from a socket line by line and put it in a buffer. For some reason, when there is no new data to return, recv returns the last couple lines it got. I was able to stop the bug by commenting out the first recv, but then I cant tell how long the next line will be. I know it's not a while(this->connected){ memset(buf, '\0', sizeof(buf)); recv(this->sock, buf, sizeof(buf), MSG_PEEK); //get length of next message ptr = strstr(buf, "\r\n"); if (ptr == NULL) continue; err = recv(this->sock, buf, (ptr-buf), NULL); //get next message printf("--%db\n%s\n", err, buf); tok[0] = strtok(buf, " "); for(i=1;tok[i-1]!=NULL;i++) tok[i] = strtok(NULL, " "); //do more stuff }

  • Can I right-click a folder in Windows 7 and choose "Open with Sublime Text"?

    - by George P. Burdell
    In Windows 7, I can do this at the command line: "c:\Program Files\Sublime Text 2\sublime_text.exe" samplefolder This launches a Sublime Text window, with the contents of samplefolder loaded in Sublime's sidebar. While this works as needed, it's inconvenient to open a command prompt every single time. Is there any way I can add this behavior to Windows Explorer's right-click menu? I'd like to be able to right-click a folder and "Open with Sublime" just like I can right-click a folder and "Scan for viruses".

  • Why is it possible to deploy a hypervisor within a hypervisor?

    - by blade3
    Hi, Why is that a hypervisor, which alledgedly needs to be on physical hardware, can be deployed within a VM? For example, XenServer (the actual hypervisor) can be deployed in an ESX VM? Why is this possible (Although not a good idea for many reasons, but still works). Also, why do people say a hypervisor needs physical hardware (from an architectural point of view, rather than obvious performance reasons). Thanks

  • Can Stopwatch be used in production code?

    - by Adrian
    Hi, I need an accurate timer, and DateTime.Now seems not accurate enough. From the descriptions I read, System.Diagnostics.Stopwatch seems to be exactly what I want. But I have a phobia. I'm nervous about using anything from System.Diagnostics in actual production code. (I use it extensively for debugging with Asserts and PrintLns etc, but never yet for production stuff.) I'm not merely trying to use a timer to benchmark my functions - my app needs an actual timer. I've read on another forum that System.Diagnostics.StopWatch is only for benchmarking, and shouldn't be used in retail code, though there was no reason given. Is this correct, or am I (and whoever posted that advice) being too closed minded about System.Diagnostics? ie, is it ok to use System.Diagnostics.Stopwatch in production code? Thanks Adrian

  • IPhone XCode programming: view called from a navigation view doesn't set its IBOutlet attributes

    - by Antonio Murgia
    I created a view Called ProgrammaView that appears when a row of a table is clicked. This view has a UILabel, a UIImageView and a UITextView. Now. ProgrammaView's Outlets have to be changed by the parameter passed to a method of the view called iniz. in this image there is first the ProgrammaView.h and then the method iniz. The problem is that the label and other stuff doesn't change! I checked 3 million times that everything between the xib file and the controller is linked. The trick to call iniz in the other viewcontrollers works well in other part of the program so i think is not that the problem. Thank you in advance!

  • How to keep the session of user login?

    - by YaW
    Hi, I have an app that requires user to register. I've got the app conected to PHP in my server to do the logic of register/login and so, this is not problem at all. But, I want to keep a session of the user in local, so the user doesn't have to login again every time he runs the app. So, I want something like this: First time user, he opens the app, register and login. Do some stuff with the app and closes it. Open the app again, the user is recognized so he doesn't need to login again. I only need to store an ID and a Username (both fetched from the DB in the login php method). What's the best way to do this?? I've thought about doing a custom preference, store the data in files or even a local DB (sqlite). Any suggestions?

  • SharePoint 2010 and VS 2010 - which releases work well?

    - by Jonesie
    I'm having a hard time finding a combination of sharepoint and vs releases that work well together. So far I have tried: SP 4730 & VS RTM SP 4747 & VS RC SP 4763 (Debug RTM ish) & VS RC All of these had issues in one or both products. I'm now reverting to SP 4747 & VS RTM. Has anyone else found a combo that works well? Specifically, I'm creating a service application with some sync framework goodness. I get errors when deploying from vs or running the powershell cmdlets to deploy and provision stuff. Thanks

  • Issue in connecting Pro9000 camera directly with OMAP3530

    - by Vinay krishna
    I have a video phone application running on an OMAP3530 board. The problem is when I connect the camera (Pro 9000) through a powered USB hub (In:100-240V, Out:5V,1A) everything works fine when I make a video call. But if I connect the camera directly to the OMAP3530 board and try to make a video call, the OMAP board is not sending any video packets captured locally. And also the PIP (Picture In Picture) is disabled.
