• Hook key & key combinations from keyboard with Qt 4.6

  - by Viet

  Let's say I have a window-less application which has only an icon on the Taskbar (Windows, Mac OS X & Linux). I want it to capture some key & key combinations, let's say Right Control + Right Shift. Upon keying in correct, combination, it will do something, say take screenshot. I can do window-less app, icon on the Taskbar and screen capture but I don't know how to monitor keyboard globally for key combinations. Please kindly advise. Any help or hint is greatly appreciated! Thanks in advance!

• Prevent Apache from answering invalid requests

  - by nickdnk

  I have an Apache web-server that acts as a web front-end for iPhone and iPad applications that communicate by POST and JSON only. Is there any way to prevent Apache from answering requests that are invalid? I can see my error log is filled with attempts to open files such as /admin.php /index.php etc - files that don't exist on my server. I believe this is possible with IIS, but can you do the same thing with Apache? Basically I want the request to appear timed out unless you post exactly the right content to the right file - or at least if you do not request an existing file. This would make the server appear non-existing to everyone but my iPhone users as all communication is SSL and directories are not really guess-able. I did disable the ServerTokens and all that, but I still get File not found etc. when I access the server requesting a random file, which is what these bots do constantly.

• Will iPhone App with future "Availability Date" show up in "New Releases" on that day?

  - by Heiko Weible

  I plan to submit my first iPhone game "The Twiggles" to the iPhone app store today. Like many people suggest, I want to set the "Availability Date" to a date way in the future and change it later. But there are two different opinions on what to do once the app is approved: A: Some people say, I have to quickly change the "Availability Date" to the date the app is approved by Apple right after I get the "app approved" mail. Otherwise it won't show up in the "New Releases" list. B: Some people say, this is not necessary (or maybe no longer necessary). I can set the "Availability Date" to some date in the future (for example, next weekend). The app will be released on that day and will show up in the "New Releases" list on that day. Who is right?

• Windows 7 very slow after restart, but fine after complete shutdown?

  - by lkm

  I have a Dell pc running Windows 7 with the Intel i3 processor. Whenever I restart the computer, the os crawls. For example, I move the mouse and then I see it move on the screen 10 seconds later... Everything runs slowly. This happens only on a restart (it's fine when I turn it on after it has been shut down). Any ideas what is causing this (I haven't installed any new software since buying it). Does it sound like a hardware or software issue?

• How do I add items to the Finder context menu in Mac OS X?

  - by mystro

  I'm in the process of porting a Windows application to OS X (we wrote it in Java so most of the code is portable), but what I'm currently unsure of is how to add context menu items in the Finder window when the user right clicks on an item (i.e. I wish to add some items to the the menu that has "Open" "Open with" , "Get Info", etc... when the user right clicks). Most of the articles I've found deal specifically with Windows (I've searched for "context menus" and "shell extension", but I believe I may be searching the wrong terms), so I'm curious as to how to go about adding this in Mac or what literature I should be reading.

• Can I get away with this or is it just too crude and unpractical ?

  - by The_AlienCoder

  I spent the whole of last night searching for a free AspNet web chat control that I could simply drag into my website. Well the search was in vain as I could not find a control that matched my needs i.e List of users, 1 to 1 chat, Ability to kick out users.. In the end I decided to create my own control from scractch. Although it works well on my machine Im concerned that It maybe a little crude and unpractical on a shared hosting enviroment. Basically this is what I did : Created an sql database that stores the chat messages. Wrote the stored procedures and and included a statement that clears old messages Then the 'crude' part : Dragged an update panel and timer control on my page Dragged a Repeater databound to the chat messages table inside the update panel Dragged another update panel and inside it put a textbox and a button Configured the timer control to tick every 5 seconds. ..and then I made it all work like this In the timer tick event I 'refreshed' the messages display by invoking Databind() on my repeater i.e protected void Timer1_Tick(object sender, EventArgs e) { MyRepeater.DataBind(); } Then in my send button click event protected void btnSend_Click(object sender, EventArgs e) { MyDataLayer.InsertMessage(Message, Sender, CurrTime); } Well It works well on my machine and Ive got the other functionalities(users list, kick out user..) to work by simply creating more tables. But like I said it seems a little crude to me. so I need a proffesional opinion. Should I run with this or try another Approach ?

• OpenGL ES perspective projection

  - by TimeManx

  I'm having a hard time understanding how glFrustum & gluPerspective work. I understand the concept of perspective projection but the functions aren't behaving how I expect them to. For example, if I set the frustum this way glFrustumf(0, 10, 0, 10, 1, 100) and have a rectangle at points 0, 0, 1, 0, 10, 1, 10, 10, 1, 10, 0, 1 then the rectangle is drawn with its left edge at -5 & right edge at 5, so the left half of the rectangle isn't visible. And if x is translated, I'd expect y to be too. But that doesn't happen either. In whatever examples I've seen, the coordinates for the projection matrix are taken as glFrustumf(-10, 10, -10, 10, 1, 100) but either way, whatever part is shown should be dependent on the rectangle's coordinates, right?

• How Do I Map a Drive Network Share Using the Linux Terminal?

  - by nicorellius

  Still getting used to Linux, and the GUI is great. I have Ubuntu 10 and I can go to Network and see the Windows network. Then double clicking this gets me to the drives that are shared. Then when I go back to the terminal and use: cd ~/.gvfs I can see the mapped drives. But it would be nice if I could this without all the mouse clicking. So how do I map network drives in the terminal, something akin to net use for Windows.

• Placing text on UIView in custom location

  - by JAM

  I am trying to calculate a position to place label on the screen. The goal is to place "word" label in lower right corner of the first square block If yellowish square is defined as myView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 70, 70)]; [self.view addSubview:myView]; [myView setBackgroundColor:[UIColor colorWithHexString:@"FFFFEC"]]; Using it, i'd like to place a label in it's lower right corner l1 = [[UILabel alloc] init]; [l1 setText:@"word"]; [l1 setFrame:CGRectMake(myView.frame.origin.x + myView.frame.size.width, myView.frame.origin.y + myView.frame.size.height, 700, 700)]; [l1 setFont:[UIFont fontWithName:@"Arial" size:10.0]]; [l1 setBackgroundColor:[UIColor colorWithHexString:@"CCFFFEC"]]; [l1 setTextAlignment:UITextAlignmentRight]; [l1 sizeToFit]; This is what happens: The matter here obviously, is in a correct offset. Knowing the font and size of text, how can one correctly calculate it?

• Form wont stay on top. How do I keep my excel form from hiding behind other windows after I browse

  - by ScottK

  I have a vb.net program that opens up an excel workbook and runs a macro ("Report") in that workbook when a button is clicked. //Workbook with macro and form xlWorkbook = xlApp.Workbooks.Open("W:Data\Excel Program.xls") //Macro: xlApp.Run("Report") //Macro opens form from workbook. I browse for my two .csv files //and then click a button to run code that creates my reports. //form closes, show the excel report after its created xlApp.Visible = True After I browse my first file and select it so that its location is displayed in my text box, the excel form then hides behind any open windows. I want this form to stay on top. It is after this code executes that the form will hide behind all other open windows: Private Sub btnBrowseFile1_Click() Dim fileName1 As String fileName1 = Application.GetOpenFilename("CSV file (*.csv), *.csv") If fileName1 <> "False" Then Me.txtFileName1.text = fileName1 End If End Sub EDIT: I still have no luck with this problem. When the excel macro is opened from a vb program I have this hiding issue...but only after browsing for a file. Why does the focus leave the form and go to Windows after browsing a file? Any one have any suggestions?

• Stopping a SoundPlayer loop at the local level

  - by EvanRyan

  I'm working on setting up an alarm that pops up as a dialog with multiple sound file options the user can choose from. The problem I'm having is creating a sound player at the local level that I can close with a button. The problem I'm having is that the sound keeps looping when I close the form because the SoundPlayer doesn't exist within the button click event. here's what I have: void callsound() { if (SoundToggle == 0) // if sound enabled { if ((SoundFile == 0) && (File.Exists(@"attention.wav"))) { System.Media.SoundPlayer alarm = new System.Media.SoundPlayer(@"attention.wav"); alarm.PlayLooping(); } if ((SoundFile == 1) && (File.Exists(@"aahh.wav"))) { System.Media.SoundPlayer alarm = new System.Media.SoundPlayer(@"aahh.wav"); alarm.PlayLooping(); } } private void button1_Click(object sender, EventArgs e) { //alarm.Stop(); Only works if SoundPlayer declared at class level this.Close(); } Is there a way I can do what I want to do by declaring the SoundPlayer instances where I am? Or is there a way to declare it at the class level, and still be able to change the sound file based on user settings?

• BST Level Traversal

  - by Dalton Conley

  Ok, so I'm trying to do a level order traversal of a binary search tree and its not working. The code below makes sense to me, but that is probably because I've been looking at it forever and I've convinced myself that it should work. void BST<T>::levelByLevel(ostream &out) { Queue<BinNodePointer> q; BinNodePointer subtreeRoot; if(myRoot == NULL) return; q.enqueue(myRoot); while(!q.empty()) { subtreeRoot = q.front(); out << subtreeRoot->data << " "; q.dequeue(); if(subtreeRoot->left != NULL) q.enqueue(subtreeRoot->left); if(subtreeRoot->right != NULL) q.enqueue(subtreeRoot->right); } } Maybe you guys could point out what I'm doing wrong because, although I understand the concept of a binary search tree, I'm not 100% on all the ins and outs.

• Selecting the correct input field using jquery

  - by rshivers

  I'm trying to select the id's of dynamic input fields in my code. When clicking a button, the form will create a form field like this: <td><input type="text" id="field_a_1"></td> <td><input type="text" id="field_b_1"></td> <td><input type="text" id="field_c_1"></td> When I click on the button again I get this: <td><input type="text" id="field_a_2"></td> <td><input type="text" id="field_b_2"></td> <td><input type="text" id="field_c_2"></td> What I want to do is select only the field id that I need to pull the value from that particular input and pass it to a variable like this: var example = $(":input:eq(0)").val(); I know that by adding the :eq(0) after the :input selector it will only grab the id for field_a_1, so how do I set it up so that I can pull just the field that I need to assign it to a variable?

• pre tag is being formatted strangely in page

  - by morpheous

  I am outputting some code in one of my pages, using a <pre> tag. The code is being output correctly, but for some strange reason, the first line of the code is indented (i.e. shifted to the right, by quite a large amount). I am not applying any style to that element, and I checked in FF Firebug and no styling is being applied, so I have no idea why the first line is shifted by so much to the right - any ideas? the code that generates the tag looks like this: <pre> <?php echo $script_code; ?> </pre> The generated code looks like this: <iframe src="http://www.example.com"> </iframe> Any ideas what may be going wrong?

• View Controller Question

  - by user341444

  First off I'm new at programming. I'm creating an app with one navigation bar controller. The app is pretty basic except for a quiz section that is comprised of 12 xibs. As the users takes the quiz a new xib is pushed onto the stack. I want to create a button that takes the user back to the home screen if they do not want to complete the quiz. The back button takes them to the previous xib which could be 11 deep. Is it possible to dismiss the modal views and reload the rootView controller? Here's the code from my delegate @synthesize window; @synthesize navigationController; (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after application launch [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; } (void)dealloc { [window release]; [navigationController release]; [super dealloc]; } This is how I'm pushing new xibs onto the stack (IBAction) showTesting: (id)sender { Testing *varTesting = [[[Testing alloc] initWithNibName:@"Testing" bundle:nil] autorelease]; [[self navigationController] pushViewController:varTesting animated: YES]; } Any help would be greatly appreciated. Thanks

• Manually manipulating ArrayList

  - by jsan

  I have an assignment where I have to create a deque, however I am not allowed to use any built-in classes or interfaces. I am implementing my deque using an array list. My problem is that when I have to, for instance, add to the beginning of the array list (beginning of the queue), i am not allowed to do this: public void addFirst(ArrayList<Integer> array) { array.add(0, int); } Is there a way to do this without using the add() function? Such as manually adding to the front and shifting the rest of the array to the right? Or maybe creating a new array list and copying...I'm not sure. Any help would be great; I have a bunch of functions to write, and getting the first one done will definitely put me in the right direction. Thanks

• Logitech SetPoint update seems to be hanging

  - by Rod

  I've just gotten a new Logitech Wireless Wave Combo MK550 mouse and keyboard. I pulled it in, and have installed the software that came on the CD, which is SetPoint 6.15. After installing it, it said that it had an update, so I started the installation for that. Now it's at a point where it says, "Approximately 30 second remaining...". It has been that way for 30 minutes, not 30 seconds. So, what's going on? I'm installing this on a Windows 7 Home Premium system, 64-bit OS.

• PHP SDK Requires two logins...doesn't recognize first

  - by Jay Konieczny

  I am using the following code to authenticate whether users are logged in or not. While users can log in, they have to click the login button twice. Additionally, sometimes even after they click the log-in button twice, my "user info" part of the page (earlier in the page than the content) shows them as logged out while the actual page shows them as logged in. Here is the code. Could someone suggest a better way of handling log-ins? function isLoggedIn($facebook) { if (isset($facebook) and $facebook->getUser() != 0) { // UserID exists, but user may still not be logged in. Let's check: try { $facebook->api('/me', 'GET'); // If this succeeds, then they are logged in. return true; } catch(FacebookApiException $e) { // Some kind of error, so not logged in. if(session_id() === '') session_destroy(); return false; } } else { if(session_id() === '') session_destroy(); return false; } } Thanks!

• New to J2EE; architecture suggestions for a service/daemon?

  - by Kate

  I am brand new to the J2EE world. As an exercise to try and familiarize myself with J2EE, I'm trying to create a tiered web-app, but I'm getting a little stuck on what the best way is to spin up a service in the background that does work. Paramters of the service: It must open and hold a socket connection and receive information from the connected server. There is a 1-to-1 correlation between a user and a new socket connection. So the idea is the user presses a button on the web-page, and somewhere on the server a socket connection is opened. For the remainder of the users session (or until the user presses some sort of disconnect button) the socket remains open and pushes received information to some sort of centralized store that servlets can query and return to the user via AJAX. Is there a J2EE type way to handle this situation? Naturally what I would think to do is to just write a Java application that listens on a port that the servlets can connect to and spawns new threads that open these sockets, but that seems very ad-hoc to me. (PS: I am also new to Stack Overflow, so forgive me if it takes me some time to figure the site out!)

• Windows 7 hangs after longer inactivity of user

  - by scooby37

  I have serveral PCs running Windows 7 in different falvors (32- / 64-bit / Professional / Ultimate / ATI / Nvidia) - they all have one problem in common... ...if I don't work on any of them for a longer time and the screen goes off as it should be (all default settings!) they sometimes go into some kind of sleep mode where I get to see the desktop or whatever I did before leaving after moving the mouse or pressing a key - but nothing reacts for a different amount of time from serveral seconds to serveral minutes! Any hint that helps solving this anoying problem would be very welcome ;-)
