• WPF: Drag/Drop to re-order grid and jiggle

  - by Echilon

  I need to implement a grid in WPF which has squares that can be dragged/dropped to be re-ordered, but I'm not sure the best way to do it. I was thinking using an ObservableCollection of squares and a UniFormGrid but although I have experience with both WPF and drag/drop, ideally I'd like to do a kind of 'jiggle' when before the user releases the mouse. Any suggestions on a good starting point?

• Alt-Tab in Unity 2D makes app icon jiggle instead of switching

  - by itsadok

  I'm using Unity 2D as my desktop, and it works fine most of the time, but every now and then, I try to Alt-Tab to switch to a different application, and instead of switching to that window, the launcher bar opens, and the icon of the application I was trying to switch to starts jiggling. If I try to switch to something else, that icon starts jiggling too. If I click on the icon with the mouse, then it stops jiggling and switches to the requested window. What is this behavior? I haven't seen any mention of jiggling icons in Unity. I don't understand the original purpose of this, and I'd like a way to fix it so that I won't have to use the mouse.

• Using OpenCl to jiggle the Pipe

  - by TOAOGG

  I've got the Idea to use OpenCL to program a simple Renderer. A clear contra is, that this approach won't benefit from the hardware as the functions on the device (I think). Would it be useful to do this in OpenCL..lets say we want to Cull as early as possible so we won't have many per vertex operations. Is it correct, that Culling is done after the Vertex-Shader? For static-vertecies who won't get effected by the shader it could be interesting to cull them before. Another idea would be an deferred renderer. So the main question is: Would it make sense to program a renderer in OpenCL (aside the effort)? The resulting picture would be drawn in OpenGL.

• Ubuntu 12.04 graphics crashing when GVIM opens TEX files

  - by Pdp Molniya

  I am having a little problem everytime I open GVIM to edit *.TEX files.... the menus die, windows jiggle (maximize and minimize quickly) and I get a 'internal error ' crash report from ubuntu (12.04). It says the problem is at /usr/lib/unity/unity-panel-service. Any tips on how to solve this? It might be related to the Latex package of vim (also I get this message when I open gvim (with or without TEX files) on terminal: (gvim:5915): Gnome-WARNING **: Accessibility: failed to find module 'libgail-gnome' which is needed to make this application accessible (gvim:5915): GLib-GObject-WARNING **: cannot retrieve class for invalid (unclassed) type `' Issue is independant of theme I just checked... Thanks a lot for your help! Cheers, Pedro

• 2D distortion of a face from an image on iOS? (similar to Fat Booth etc.)

  - by Dominik Hadl

  I was just wondering if someone knows about some good library or tutorial on how to achieve a 2D distortion of a face taken from an image taken by the user. I would like to achieve a similar effect to the one in Fatify, Oldify, all those Fat Booths, etc., because I am creating an app where you will throw something at the face and I would the face to jiggle and move when the object hits it. How should I do this?

• What library is used for the main menu in the facebook iOS app?

  - by Seth

  I'm making an app that has more options than will easily fit into a UITabBarController. I wanted to use something like what the facebook app has for its main menu. My guess is that it isn't proprietary to facebook, because the SCVNGR app uses something similar. This library lets you re-order the icons the way you can re-order the apps from the main menu (i.e. press and hold - icons jiggle - you can drag them around). Does anyone know what library provides this UIView? I'd like to use it if possible. Thanks!

• How to completely disable laptop sound?

  - by Alvaro Rodriguez

  I have a HP Pavillion DV7 laptop with win 8 pro. The laptop has an unidentified problem with sound drivers or hardware that sometimes causes volume to constantly jiggle up and down. This is very annoying because of these consequences: Renders mute unusable - as the volume changes the sound unmutes automatically Causes an annoying win 8 "surface UI" notification to appear constantly in the upper left corner, which is distracting enough by itself, but more importantly Renders the whole "surface UI" unusable, because it loses focus whenever the sound changing notification appears When the jiggling happens, the laptop also loses the ability to redirect sound to earphones - sound comes out of the speakers even if earphones are connected. To solve these issues I want to completely disable sound in the laptop (I've tried reinstalling drivers several times to no end). I have tried disabling all sound related drivers and devices in the Device Manager but Windows re-enables those automatically whenever I restart the laptop. The BIOS doesn't have any settings to disable sound hardware either. Please don't suggest having the laptop sound serviced or fixed. It's not worth the expense. I just want to remove sound support so I can use it normally. It is very unusable as it is now.

• Problems with synaptic touchpad

  - by penlite

  The "enhanced" features of the synaptics touchpad (ie scroll, pinch zoom) on my windows 7 64 bit dell studio 17 only work intermittently. This was an issue with the original OEM driver and also with the new driver from synaptics - please do not suggest that i update, reinstall, install as administrator, check or jiggle the driver - if i hear that one more time i will freak out. I have researched this for days and appears to be a common problem without a solution (many suggestions to update the driver though -argh). Dell and synaptics have not been helpful. I have checked that syntpehn.exe and syntphelper.exe are running (sometimes the UAC seems to block syntpehn.exe from running at startup). When the touchpad fails i can still use it to control the pointer and access the synaptics settings although some of the options are disabled (greyed out or simply unresponsive). It is the only pointing device i have installed - i had a logitech trackball attached but have uninstalled all software and drivers (including hidden devices) as per synaptic. It is also the only device using IRQ 12. Any help would be greatly appreciated except "update the driver".

• How to inhibit suspend temporarily?

  - by Zorn

  I have searched around a bit for this and can't seem to find anything helpful. I have my PC running Ubuntu 12.10 set up to suspend after 30 minutes of inactivity. I don't want to change that, it works great most of the time. What I do want to do is disable the automatic suspend if a particular application is running. How can I do this? The closest thing I've found so far is to add a shell script in /usr/lib/pm-utils/sleep.d which checks if the application is running and returns 1 to indicate that suspend should be prevented. But it looks like the system then gives up on suspending automatically, instead of trying again after another 30 minutes. (As far as I can tell, if I move the mouse, that restarts the timer again.) It's quite likely the application will finish after a couple of hours, and I'd rather my PC then suspended automatically if I'm not using it at that point. (So I don't want to add a call to pm-suspend when the application finishes.) Is this possible? Any advice would be appreciated. Cheers. EDIT: As I noted in one of the comments below, what I actually wanted was to inhibit suspend when my PC was serving files over NFS; I just wanted to focus on the "suspend" part of the question because I already had an idea how to solve the NFS part. Using the 'xdotool' idea given in one of the answers, I have come up with the following script which I run from cron every few minutes. It's not ideal because it stops the screensaver kicking in as well, but it does work. I need to have a look at why 'caffeine' doesn't correctly re-enable suspend later on, then I could probably do better. Anyway, this does seem to work, so I'm including it here in case anyone else is interested. #!/bin/bash # If the output of this function changes between two successive runs of this # script, we inhibit auto-suspend. function check_activity() { /usr/sbin/nfsstat --server --list } # Prevent the automatic suspend from kicking in. function inhibit_suspend() { # Slightly jiggle the mouse pointer about; we do a small step and # reverse step to try to stop this being annoying to anyone using the # PC. TODO: This isn't ideal, apart from being a bit hacky it stops # the screensaver kicking in as well, when all we want is to stop # the PC suspending. Can 'caffeine' help? export DISPLAY=:0.0 xdotool mousemove_relative --sync -- 1 1 xdotool mousemove_relative --sync -- -1 -1 } LOG="$HOME/log/nfs-suspend-blocker.log" ACTIVITYFILE1="$HOME/tmp/nfs-suspend-blocker.current" ACTIVITYFILE2="$HOME/tmp/nfs-suspend-blocker.previous" echo "Started run at $(date)" >> "$LOG" if [ ! -f "$ACTIVITYFILE1" ]; then check_activity > "$ACTIVITYFILE1" exit 0; fi /bin/mv "$ACTIVITYFILE1" "$ACTIVITYFILE2" check_activity > "$ACTIVITYFILE1" if cmp --quiet "$ACTIVITYFILE1" "$ACTIVITYFILE2"; then echo "No activity detected since last run" >> "$LOG" else echo "Activity detected since last run; inhibiting suspend" >> "$LOG" inhibit_suspend fi

• USB ports causing Wireless and Mobile Phone tethering drop out

  - by chrolli

  I have a problem with my USB ports and I can't seem to pinpoint the problem. I'm hoping that I can get some idea as to how to troubleshoot my problem. Problem description: I recently bought a USB Wireless Adapter in order to connect my Desktop PC to the WLAN. The dongle keeps dropping off connection regularly on average once a minute. And the connection is slow. What I've tried: I installed a network scanner to determine signal strength. The PC/adapter combo is getting about 70% signal strength. I have a laptop that has an internal Wireless adapter. I moved the laptop near the location of the PC. The signal strength was above 90%. I installed the USB adapter on the laptop. I placed the laptop near the location of the PC. The signal strength was above 80%. And there is no drop out issue. I've isolated the problem to be on the PC. I used internet tethering on my mobile phone in order to test the USB ports. I get the same problem, themobile phone keeps dropping in and out. I plugged the adapter and phone on all USB ports, and it is still dropping out on all ports. I've isolated the problem to be the Motherboard, USB hub. I updated the BIOS, and USB driver. Still dropping out. I noticed that when I used the mobile phone tethering method, the phone (iphone 5) is guarenteed to drop out and does not appear to charge if I jiggle the the 8-pin connector on the base of the phone. If I push the pin tightly on the phone, the phone starts charging, as soon as I let go, it stops and drops out from the PC. This is strange because this doesn't happen when it is plugged to the powerboard. Which means that the 8 pin connector is fine. I'm not sure what the problem is. I assume that it is to do with the USB ports not supplying enough power which in turn causes the devices to intermittently drop out. The reason I say this is because the USB cable works fine when plugged into a powerboard with enough power supplied to the phone. Only when it is plugged into the USB port on the PC, does it drop out. My motherboard is Asus P8z68-v le. My Wireless adapter is the D-link DWA131. I can't seem to find any settings in the BIOS to increase the south bridge voltage so as to supply more power to the USB ports. Although this problem only occurs when I'm trying to hook up to a device supplying internet connection. My USB HDD, Flash drives, and Mouse and Key are working fine! Any suggestions please?

• Loose component cables causing HDMI video problems

  - by jwir3

  I'm not sure this is the correct forum, but I'll ask anyway. I have an A/V setup at home that has something like the following: Five Components (actually a few more, like a CD player, but they don't really relate to this question): Older Pioneer Receiver Digital Set Top Box Sony BluRay Player Samsung Plasma TV Speakers The reason for the receiver is so that all the sound can go through the speakers, rather than some going to the TV speakers and some to the external speakers. They are connected as follows: Digital Set Top Box connects via component video to Samsung TV directly via Component 2 (audio goes to Older Pioneer Receiver). Sony BluRay player is connected via HDMI 1 to TV, but audio goes to the receiver. Now, the problem I'm having is that when I have the digital set top box connected, there are times when the Netflix or Hulu streams I watch through the Sony BluRay player (it's connected to a router for internet access) will lose video. What I mean by this is that the sound of the episode will keep playing, but the screen will go black. If I jiggle the component cables, it will often come back. If I disconnect the component cables, it will always come back. I've noticed that one of the connections (the red component cable) doesn't like to sit very well in the component socket in the back of the digital set top box. It seems like there is a bad connection here, but it doesn't seem like this should be affecting the HDMI input at all. What I've noticed, though, is that when I disconnect the digital set top box completely (i.e. remove the component cable from the back of the TV), the problem seems to resolve itself. I'm not talking about actually removing the cable physically, because I thought perhaps the cables were mashing against one another, and possibly jiggling each other loose. To correct this possible problem, I took the component cable completely out of the cable ties it was in in the back of my entertainment center, as well as pulled the digital set top box out from the entertainment center altogether. It's now connected directly to the TV, without any other cables touching it to cause some kind of weird interference or just physical pulling on the cable. Same problem. If, however, I disconnect the component cable and just leave it sitting behind the TV, then the problem goes away. So, my question is this - what could be causing this? Is it a case where it's an improperly shielded component cable that's causing interference with the HDMI input, or something that's wrong with the TV? It's an intermittent problem, so it's difficult to track down. The TV isn't that old, so it's probably still under warranty. I'm just wondering if there is something else I can do that might reduce this problem without having to haul a massive television set out of my house to get repaired/replaced.

• Win32: IProgressDialog will not disappear until you mouse over it.

  - by Ian Boyd

  i'm using the Win32 progress dialog. The damnest thing is that when i call: progressDialog.StopProgressDialog(); it doesn't disappear. It stays on screen until the user moves her mouse over it - then it suddenly disappers. The call to StopProgressDialog returns right away (i.e. it's not a synchronous call). i can prove this by doing things after the call has returned: private void button1_Click(object sender, EventArgs e) { //Force red background to prove we've started this.BackColor = Color.Red; this.Refresh(); //Start a progress dialog IProgressDialog pd = (IProgressDialog)new ProgressDialog(); pd.StartProgressDialog(this.Handle, null, PROGDLG.Normal, IntPtr.Zero); //The long running operation System.Threading.Thread.Sleep(10000); //Stop the progress dialog pd.SetLine(1, "Stopping Progress Dialog", false, IntPtr.Zero); pd.StopProgressDialog(); pd = null; //Return form to normal color to prove we've stopped. this.BackColor = SystemColors.Control; this.Refresh(); } The form: starts gray turns red to show we've stared turns back to gray color to show we've called stop So the call to StopProgressDialog has returned, except the progress dialog is still sitting there, mocking me, showing the message: Stopping Progress Dialog Doesn't Appear for 10 seconds Additionally, the progress dialog does not appear on screen until the System.Threading.Thread.Sleep(10000); ten second sleep is over. Not limited to .NET WinForms The same code also fails in Delphi, which is also an object wrapper around Window's windows: procedure TForm1.Button1Click(Sender: TObject); var pd: IProgressDialog; begin Self.Color := clRed; Self.Repaint; pd := CoProgressDialog.Create; pd.StartProgressDialog(Self.Handle, nil, PROGDLG_NORMAL, nil); Sleep(10000); pd.SetLine(1, StringToOleStr('Stopping Progress Dialog'), False, nil); pd.StopProgressDialog; pd := nil; Self.Color := clBtnFace; Self.Repaint; end; PreserveSig An exception would be thrown if StopProgressDialog was failing. Most of the methods in IProgressDialog, when translated into C# (or into Delphi), use the compiler's automatic mechanism of converting failed COM HRESULTS into a native language exception. In other words the following two signatures will throw an exception if the COM call returned an error HRESULT (i.e. a value less than zero): //C# void StopProgressDialog(); //Delphi procedure StopProgressDialog; safecall; Whereas the following lets you see the HRESULT's and react yourself: //C# [PreserveSig] int StopProgressDialog(); //Delphi function StopProgressDialog: HRESULT; stdcall; HRESULT is a 32-bit value. If the high-bit is set (or the value is negative) it is an error. i am using the former syntax. So if StopProgressDialog is returning an error it will be automatically converted to a language exception. Note: Just for SaG i used the [PreserveSig] syntax, the returned HRESULT is zero; MsgWait? The symptom is similar to what Raymond Chen described once, which has to do with the incorrect use of PeekMessage followed by MsgWaitForMultipleObjects: "Sometimes my program gets stuck and reports one fewer record than it should. I have to jiggle the mouse to get the value to update. After a while longer, it falls two behind, then three..." But that would mean that the failure is in IProgressDialog, since it fails equally well on CLR .NET WinForms and native Win32 code.
