  • Check if hydrated doctrine result is NULL

    - by iggnition
    Hi, I'm trying to check if a result in my DQL is NULL. I got the following DQL query: $q = self::createQuery("l") ->select('i.*, s.aantal, m.naam, c.cat_naam, a.app_id') ->from('InstalledBase i, i.Spare s, i.Apparaat a, a.Categorie c, a.Merk m') ->execute(); return $q; Now i want to check if the s.aantal is NULL so i do: if(is_null($installedbase->Spare->spare_id)) when the variable is NOT null everything works, but when it is actually NULL i get a E notice message: Notice: Trying to get property of non-object in \installedbase\templates\_index.php on line 29 It does see that it is null though because the if condition is executed. Weird thing is i'm doing the exact same thing on another page where it works no problem. But i must be doing something wrong or stupid since those messages generally don't show for nothing. So can anybody explain this to me? :)

  • Smooth mousover images inside scaled Flex App?

    - by Josh Handel
    I have a flex app I am scaling using systemManager.stage.scaleMode=StageScaleMode.NO_BORDER; for the most part it works well except for my bitmap data (mostly png's from the designers). I can set the mx:image tags to smoothBitmapContent=true and that works great for everything except my mouseover objects. When I do a mouseover, the source is being changed from one embedded image to another embedded image. I have tried several (many) online "smoothimage" classes, and tried to write my own, I have tried to reset smoothBitmapContent every chance I get but still no dice. It seems to mee that because I am scaling at the app level, that the flopped out bitmap is not getting smoothed when it renders. Does anyone have any suggestions on how to keep things smooth (perhaps there is a flag to tell Flex to smooth stuff when it scales it?). Thanks Josh

  • Cocoa: Creating a Window with a Variable Number of Interface Elements

    - by Rui Pacheco
    Hi, I've a window that will have an unknown amount of text fields, determined by the content of a remote server. In high level terms, how should I go about this? Create a custom view or create an empty window with a backing NSWindowController and then add stuff to it when the window is opened? I've seen the examples on the O'Reilly Cocoa book and those effectively create a custom NSView. Is this the right way to do it, 8 year later?

I have a TreeView that I need to know if it is still suspend. myTreeView.BeginUpdate(); myTreeView.SuspendLayout(); // Do Stuff. myTreeView.EndUpdate(); myTreeView.ResumeLayout(); Because i have this code in a recursive function I want to know if the TreeView is already been suspended.

  • How to Disable the Move System Menu Item?

    - by Andreas Rejbrand
    In Microsoft Windows, this works: mnu := GetSystemMenu(h, false); EnableMenuItem(mnu, SC_CLOSE, MF_BYCOMMAND or MF_GRAYED); But this does not work: mnu := GetSystemMenu(h, false); EnableMenuItem(mnu, SC_MOVE, MF_BYCOMMAND or MF_GRAYED); Hence I know how to disable the "Close" system menu item of a window, but not the "Move" item. How do I do that? Update Of course one alternative to using the very nice function EnableMenuItem, is to use SetMenuItemInfo: FillChar(info, sizeOf(info), 0); with info do begin cbSize := sizeOf(info); fMask := MIIM_STATE; fState := MFS_GRAYED; end; SetMenuItemInfo(mnu, SC_MOVE, false, info); But this again works perfectly for SC_CLOSE, but not at all for SC_MOVE!

  • Greek/latin scientific JLabel in Java Swing application

    - by MartinStettner
    For a scientific application I want to design an input form which lets the user enter certain parameters. Some of them are designated using greek letters, some of them have latin letters. The parameter names should be displayed using ordinary JLabel controls. On Windows, the Tahoma font (which is used for Labels by default) contains both latin and greek letters, so I simply set the Text property of the label to a greek (unicode) string and everything works fine. I'm wondering if this works also without modifications on Linux and OSX systems resp. for which Java/OS versions this would work. Also I'm curious if there's an easy way to show subscripts in labels ("\eta_0" in TeX), but this is not that important for my application ...

  • Grails: JSONP callback without id and class in JSON file

    - by Klaas
    Hi, I am working on a REST based interface where people get a json file. The client needs to access the file from another Domain. I use jsonp which works so far. My problem is the rendering in Grails. At the moment I use the 'as JSON' to marshalling the object: render "${params.jsoncallback}(${user as JSON})" The Json file getting to the client inclused all attributes, incluing the id and class, which I do not want to have in there. In case it is not jsonp, I do it this way, which works great: render(contentType:'text/json'){ userName user.userName userImage user.userImage : : } So how do I get the id and class attributes out of the json when rendering "user as JSON"? Any idea? best regards, Klaas

  • How can I set a field to null in a Pre-Update Plugin

    - by Juergen
    I developed a Pre-Update Plugin for the Case entity. In this plugin I want to set a string field to a new value. It works smoothly if the new value is not null. But if the new value si null, it is just ignored. This works: Incident caseTarget = ((Entity) localContext.PluginExecutionContext.InputParameters["Target"]).ToEntity<Incident>(); caseTarget.ProductSerialNumber = "new value"; After the execution of the plugin, the ProductSerialNumber field has value "new value". This doesn't work: Incident caseTarget = ((Entity) localContext.PluginExecutionContext.InputParameters["Target"]).ToEntity<Incident>(); caseTarget.ProductSerialNumber = null; After the execution of the plugin, the ProductSerialNumber field has still its old value. How can I set the target's field to null?

  • Modifications in default document (ASP.NET+IIS7) won't take effect

    - by Wilson
    We have a website developed by ASP.NET+IIS7 and its default document is default.aspx. It works fine. But when we tried to switch the default to index.html, weird things happened. We have modified web.config as follows: <defaultDocument> <files> <clear /> <add value="index.html" /> </files> </defaultDocument> and we have clear everything under C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files``, and restart the worker process. We even changed the name of Default.aspx to dddd.aspx. But everything stays the same when accessing with http://localhost/<MyAppName>/! And when we tried to access with http://localhost/<MyAppName>/index.html, it works fine. Any suggestions would be highly appreciated.

  • C# setup project output automatically start with administrative rights

    - by Alex
    Hi, i've created an setup project for a .net-application which works fine. The problem is, that the application begins to write log-files after startup and this requires administrative rights on windows vista and windows 7. I know there are some folders which i could use to write into without administrative rights. When i start the application as administrator, everything works fine. I asked myself, if it's possible to change the setup project in visual studio in a way that the installed application automatically owns administrative rights on the target system? Thanks for every help in advance! Alex

  • Check if serial port is listening

    - by Hyposaurus
    I have an Arduino sending and receiving instructions with a python script via a serial port. The Arduino takes a button state and when it is pushed it will send a message via serial to a python script and await a response. (via Serial.available()). Works well enough. However if the python script has crashed for whatever reason (ideally it will run in the background, so cant be easily checked) the Arduino will wait forever and even on a script restart will we unavailable. Is there a way for my Arduino to check if there is something listening on the serial port? (and alert me with flashing lights etc if not) or is this not how serial works? Worst case I guess I could use a timeout, although that is not ideal.

  • Illegal instruction in Assembly

    I really do not understand why this simple code works fine in the first attempt but when putting it in a procedure an error shows: NTVDM CPU has encountered an illegal instruction CS:db22 IP:4de4 OP:f0 ff ff ff ff The first code segment works just fine: .model small .stack 100h .code start: mov ax,@data mov ds,ax mov es,ax MOV AH,02H ;sets cursor up MOV BH,00H MOV DH,02 MOV DL,00 INT 10H EXIT: MOV AH,4CH INT 21H END However This generates an error: .model small .stack 100h .code start: mov ax,@data mov ds,ax mov es,ax call set_cursor PROC set_cursor near MOV AH,02H ;sets cursor up MOV BH,00H MOV DH,02 MOV DL,00 INT 10H RET set_cursor ENDP EXIT: MOV AH,4CH INT 21H END Note: Nothing is wrong with windows config. I have tried many sample codes that work fine Thanks

  • Jquery and frames

    - by Shard
    I am currently working on a web application that has been created using a magnitude of frames that stretch down up to 5 times, The issue is that i need to preform some jquery magic throughout the website. What would be the best way to go about this (other than rewriting it which i have considered)? EDIT: The Frame Structure is something along the lines of this: Index.html menu.html banner.html list.html footer.html /lib/index.html header.html body.html footer.html The magic i am referencing is a few hot key shortcuts, find and replace that kind of stuff

  • Cannot select/edit TineMCE-generated table

    - by Rakward
    I'm currently using TinyMCE edit in my drupal-website, problem is that beneath the editor, some of the table is sticking out. If I remove the height set by javascript with firebug, it looks fine, even after resizing. So I want to remove the height with JS, I've put this function at the end of my page: $('table#edit-body_tbl').removeAttr('style'); However nothing happens. I test the function in firebug's console, it works perfectly. Basically, the problem is the JS works, but it wont do anything if I simply load it at the end of the page, even in the document.ready function. The TineMCE script is loaded before my script so I should be able to select/edit/delete elements generated by it no? Does anybody know why or how I can force the page to really load my function in the end(currently it is right in front of the -tag)? Other functions in the script work, except this thing ...

  • How do I put files in the TFS Build drop location

    - by Scott Langham
    Hi, I'm new to using TFS build. I've got a build defined that runs as a continuous integration. It creates a drop folder, but there's nothing in it. What's the best practice for moving stuff in the drop folder? I've seen a Binaries folder, do I need to copy things into their, or do I alter the TFSbuild.proj in some way to copy the files I want to the drop folder? Thanks.

  • Problem running ASP.NET MVC 2 website on IIS7

    - by Charlie
    I'm trying to deploy my ASP.NET MVC 2 website from VS2010 beta 2 to IIS7. The publish works fine but none of the routes work, so when I go to the URL http://localhost/myapp/Home/Index I get the error: HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. I'm deploying to a virtual directory which is using an app pool configured for the .NET 4 framework with managed pipeline mode set to integrated. Also, if I go Basic Settings-Test Connection, both tests pass. From what I understand, it should just work? I don't have any problems deploying Nerd Dinner from VS2008, that works fine.

  • Create an autocompleter like the Facebook status update

    - by Terw
    Hello I'm trying to create a div with contenteditable like the Facebook status update. Then I mean I want to show an autocomplete box when the user have written @. How would you do that. Currently I'm just playing with keypress and check if the keycode = 64. Somehow that works, but it doesn't validate if there's a space before the alfa, or if the user has unfocused the box, then focused it again. Any ideas? Or do you know about any plugin that works something like that? Tnx

  • Delphi LoadLibrary Failing to find DLL other directory - any good options?

    - by Chris Thornton
    Two Delphi programs need to load foo.dll, which contains some code that injects a client-auth certificate into a SOAP request. foo.dll resides in c:\fooapp\foo.dll and is normally loaded by c:\fooapp\foo.exe. That works fine. The other program needs the same functionality, but it resides in c:\program files\unwantedstepchild\sadapp.exe. Both aps load the DLL with this code: FOOLib := LoadLibrary('foo.dll'); ... If FOOLib <> 0 then begin FOOProc := GetProcAddress(FOOLib , 'xInjectCert'); FOOProc(myHttpRequest, Data, CertName); end; It works great for foo.exe, as the dll is right there. sadapp.exe fails to load the library, so FOOLib is 0, and the rest never gets called. The sadapp.exe program therefore silently fails to inject the cert, and when we test against production, it the cert is missing, do the connection fails. Obviously, we should have fully-qualified the path to the DLL. Without going into a lot of details, there were aspects of the testing that masked this problem until recently, and now it's basically too late to fix in code, as that would require a full regression test, and there isn't time for that. Since we've painted ourselves into a corner, I need to know if there are any options that I've overlooked. While we can't change the code (for this release), we CAN tweak the installer. I've found that placing c:\fooapp into the path works. As does adding a second copy of foo.dll directly into c:\program files\unwantedstepchild. c:\fooapp\foo.exe will always be running while sadapp.exe is running, so I was hoping that Windows would find it that way, but apparently not. Is there a way to tell Windows that I really want that same DLL? Maybe a manifest or something? This is the sort of "magic bullet" that I'm looking for. I know I can: Modify the windows path, probably in the installer. That's ugly. Add a second copy of the DLL, directly into the unwantedstepchild folder. Also ugly Delay the project while we code and test a proper fix. Unacceptable. Other? Thanks for any guidance, especially with "Other". I understand that this issue is not necessarily specific to Delphi. Thanks!
