  • Shortcuts located in "D:\Program Data\..." not working even though they're pointing to the right targets (Windows 7)

    - by Kevin
    I just made a fresh install of my windows 7 home premium using my laptop's recovery disks (HP Pavilion dv6-2151cl) using minimal settings. After install, I set up "Program Data" and "Users" to my D partition to save space changing the folders in the registry. Then I updated windows (including W7 SP1), and installed all other programs. After installing all other programs I noticed that the icons of all new programs (not included in the windows install) in "All Programs" had a blank sheet as icon and they don't do anything. Looked into "D:\Program Data\Microsoft\Windows\Start Menu\Programs" in the windows explorer and the same is true there. All the shortcuts in C: and "D:\Users..." work both in the "Windows Explorer" and "All Programs". Also I noticed that the shortcuts do display the right icons inside the "open" dialog boxes. And if I copy the shortcuts in "D:\Program Data..." to the desktop they also work as expected. I checked file association for .lnk and it was OK, but also tried the registry fixers for this file association and they had no effect. There are no missing programs that I can tell in the "All Programs" menu, the just don't do anything if they lay in "D:\Program Data...". Any thoughts on how to make Windows 7 treat shortcuts in "D:\Program Data..." as they should?

  • How can I make my Super keys (Windows Key) behave more like Ctrl/Alt/Shift in Linux

    - by deltaray
    After using the Ctrl + "arrow keys" for 13 years to switch virtual desktops in X windows, I've been convinced recently to change to using the Super keys instead (the windows key and the context menu key, which I've remapped). This all works fine for the most part. However, something is still picking up the key events that these keys are sending as if they are a normal alphanumeric like key. For example, I first noticed this in Google Docs spreadsheet that if I press the windows key alone over top of a cell, that it starts editing that cell. It doesn't insert anything, it just sends a key event that Firefox sees and starts editing the cell. This caused problems on a collaborative document I was working on as the way Google docs works, it led to me accidentally erasing the data in a few fields before I realised what was going on. I like using the super keys, but I want them to behave more like a Ctrl or Alt key does in that its a modifier key and doesn't send anything until a second key is pressed. My setup is the following: Ubuntu 10.10 XFCE 4 Microsoft Natural Ergo 4000 keyboard (with the logo scratched out) The following is my .Xmodmap file: remove Lock = Caps_Lock keycode 66 = Escape ! The below maps my other windows context menu key. keycode 135 = Super_R Edit: As requested, here is the relevant output from xev for a keypress and keyrelease of my Super_L (left windows key) KeyPress event, serial 34, synthetic NO, window 0x8200001, root 0x15d, subw 0x0, time 2428849342, (177,174), root:(182,228), state 0x10, keycode 133 (keysym 0xffeb, Super_L), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 34, synthetic NO, window 0x8200001, root 0x15d, subw 0x0, time 2428849430, (177,174), root:(182,228), state 0x50, keycode 133 (keysym 0xffeb, Super_L), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False

  • Is it possible to theme Windows 7 like XP?

    - by LonelyPixel
    Everybody seems to mean the window frame colour and a set of desktop background pictures when they're talking about Windows 7 themes. Does anybody remember what themes used to be in Windows XP? You could actually alter the appearance of the window frame, how close buttons and menu popups looked, put a texture on the taskbar, all those funny things. Microsoft themselves have published a number of XP themes over time (Luna on XP, Royal on MCE2005, Zune later on). I don't say that most of those and the numerous third party XP themes were beautiful or even practical. But it was possible to create something nice. In Windows 7 (I suppress the existence of Windows Vista...) such a theme could well be used to increase readability to a level before Aero Glass again. I mean, you cannot really tell whether a Glass window is active or not. I've been tweaking the colours and transparency levels a lot recently but the only safe indicator is the close button: it's red when the window is active, it's colourless otherwise. Then there's the window title. It is always painted black, on however dark a background. Again, regardless of whether the window is active or not. Turning off Aero is not an option in Windows 7 anymore. Classic design looks just ugly there. It already wasn't exactly looking good on XP with the wide start menu. So, can we increase the readability of the Windows 7 UI with themes like in XP or didn't Microsoft learn a thing since the Windows 7 Preview "Vista"?

  • HP LaserJet 1515: Disable "refill" warning

    - by Pekka
    I have a HP LaserJet 1515 connected to a Windows 7 PC. The Magenta cartridge is empty; the printer shows a warning to that effect, and won't let me print even black-and-white documents any more. I can't turn the warning off manually using the printer's small console: When I try to enter any menu, the display says "Menu access disabled". I have no idea why. There is a setting to override the warning, but it can't be changed using the Network interface in the browser (Although it is there on the status page) According to the manual,the HP printing tool is supposed to offer a switch for this, but it won't install on my Windows 7. It just rumbles about for half an hour, to magnificently exit with an "unknown error" requiring a reboot. On second look, the problem seems to be that Windows 7 just isn't supported. There is no download link for the tool when you specify Windows 7 as your OS. I just want to print a black-and-white-document on a printer whose black cartridge is still 65% full. Is this indeed impossible? On second thought, I'm cross-posting this on the HP support forum. I'll update here if anything comes up.

  • Shell replacement for kiosk environment with desktop icons

    - by tuesprem
    I have to deploy around 80 touch-screen terminals for my company. We're going to run several Windows applications on those terminals and they'll be operated by touch input only. I basically want those machines to run in a kiosk mode, so employees won't be able to launch any programs than the ones they're supposed to (also, this will hide the task bar/start menu, which will give it a much nicer, corporate look). There's usually one app that should automatically launch on startup and other apps that can be launched from the desktop. I've tried to accomplish this (under Windows 7 Pro) with a custom shell replacement. This removes the task bar/start menu like I described earlier. I used an AutoHotKey script for this, because it's easy to, for instance, define hotkeys so admins will still be able to launch stuff like Windows Explorer (okay, I know I could just launch it from the task manager [Ctrl+Shift+Esc] but I'm considering locking that as well). So far so good. Some problems though: No desktop icons. Needed to launch apps from the desktop. No wallpaper. Required for CI. Is there any way around this? I wouldn't mind using another shell replacement, as long as it's reasonably lightweight. I'd love to get the wallpaper and desktop icons to show with something like AutoHotKey though. Thanks!

  • Windows 7 Taskbar Icons Randomly Disappearing

    - by Ryker
    This is a problem that i'm totally stumped on. Taskbar Icons that are pinned, as well as open program thumbs keep disappearing. This is totally random, no set pattern. I've tried updating drivers for the vid card, rolling back to old drivers, nothing seems to work. I've also tried the usual uncheck hide the taskbar and recheck, changing the start menu, keeping commonly used programs in start menu, etc. This is using an add-in card which is a necessity. Here is the specs on the machine: New Dell Optiplex 390 i3 2100 Proc 3gb Ram, Windows 7 32-bit. The add in card is an Nvidia 8400 GS model. I've tried different versions of the 8400gs, from MSI, or from other manufactureres and regardless it keeps happening. After the Icons disappear, I can log out and log back in and they return, but disappear again. I can reinstall the drivers for the vid card and it fixes it for a few days, and then they disappear again. There isn't any set pattern of days that it happens, software being used, etc. Another user in the office had the same problem with the exact same machine, but updating the vid card drivers fixed the issue. Anyone?

  • IE8 page reload hangs

    - by Rod
    When a 7mb HTM file is first opened (by clicking on the file icon or using Open With), both IE8 and Firefox display this browser file quickly. After the file is closed, Firefox will reopen this file quickly, but IE8 appears to hang during the reopen. Clearing the IE cache does not help. However, IE will reopen the file quickly again only if the File/Open/Browse feature of the menu bar is used (clicking on the file icon can be used only once between computer reboots). Testing suggests that the problem relates to the number of HTML hyperlinks pointing to another part of the file. There are many hyperlinks, but they are not a problem during the first load of the document (between computer reboots). What needs to be fixed to avoid use of the workaround? Using Windows XP SP3 Update 6/23/12 - Controlled testing shows that the number of hyperlinks is not the problem. The way this large file is opened is the difference: 1) from the IE menu bar, File/Open/Browse is consistent and fast (but not as fast as FF). 2) clicking on the file name in the folder (even when IE is the default program for this file type) causes a much delayed load of the file. Creating a smaller file demonstrates the delayed load, but verifies that the load eventually occurs.

  • No "New Folder" button in windows 7

    - by user1125620
    My sibling's laptop is running windows 7 x64. The torrents folder in Documents doesn't show the New Folder button. ctrl+shift+n doesn't work either. I tried EVERYTHING here: Can't create new folder from anywhere in Windows 7 ..but nothing worked. As with the OP there, running the .reg file brings an error that says something about not being able to change the registry value while something is using it. I removed one entry at a time in the .reg file until I narrowed down the ones that were causing the problem, which were in HKEY_CLASSES_ROOT/CLSID. The only different reg value, however, was in HKEY_CLASSES_ROOT\CLSID{11dbb47c-a525-400b-9e80-a54615a090c0}\InProcServer32, for which the default value was %SystemRoot%\system32\explorerframe.dll and the value trying to be set ExplorerFrame.dll. I'm on windows 7 32bit and that's the same value I have for the entry, so I doubt that's it. The only thing I think is slightly off is that there is a user group with a strange name that only has execute and read access, and I can't grant it full control. Every time I try, it acts as if it works, but doesn't change it. I tried booting into safe mode and changing it, but it did the same thing. It is the folder where utorrent puts any new downloads, so it's possible utorrent did something, though that's never happened to me before. edit: I had renamed the folder to something else to avoid the problem, and then went onto my own computer to try to figure out what was wrong (I personally don't like using the touchpad on laptops). While searching, my sibling starting watching a movie. I minimized the movie and saw that the same thing had happened to the folder I renamed. Also changed was the file layout. It showed the different days and the files modified on those days. So, I was able to fix it by doing: Clicking Organize Layout Menu Bar On the menu bar clicking View Arrange By Folder

  • Why html frame behave differently in Firefox and IE8 ?

    - by Frank
    I use html frame on my webiste, it's been running for I while, usually I only use Firefox to surf the net, my site looks and functions ok, but today I suddenly found IE8 has a problem with the frame on my site, if I click on the top menu items, it's supposed to display the content in the lower part of the frame, it does this correctly in Firefox, but in IE8, it displays the content in the upper part of the frame and replaces the menu items. In order to give more details, I'll include a simplified version of my html pages, at the top level there are two items, an index.html page and a file directory, all the pages except the index.html are in the directory, so it looks like this : index.html Dir_Docs 00_Home.html 00_Install_Java.html 00_Top_Menu.html 01_Home_Menu.html 01_Install_Java_Menu.html 10_Home_Welcome.html 10_How_To_Install_Java.html [ index.html ] <Html> <Head><Title>Java Applications : Tv_Panel, Java_Sound, Biz Manager and Web Academy</Title></Head> <Frameset Rows="36,*" Border=5 Bordercolor=#006B9F> <Frame Src=Dir_Docs/00_Top_Menu.html Frameborder=YES Scrolling=no Marginheight=1 Marginwidth=1> <Frame Src=Dir_Docs/00_Home.html Name=lower_frame Marginheight=1 Marginwidth=1> </Frameset> </Html> [ 00_Home.html ] <Html> <Head><Title>NMJava Application Development</Title></Head> <Frameset Cols="217,*" Align=center BorderColor="#006B9F"> <Frame Src=01_Home_Menu.html Frameborder=YES Name=side_menu Marginheight=1 Marginwidth=1> <Frame Src=10_Home_Welcome.html Name=content Marginheight=1 Marginwidth=1> </Frameset> </Html> [ 00_Install_Java.html ] <Html> <Head> <Title>Install Java</Title> </Head> <Frameset Cols="217,*" Align=center BorderColor="#006B9F"> <Frame Src=01_Install_Java_Menu.html Frameborder=YES Name=side_menu Marginheight=1 Marginwidth=1> <Frame Src=10_How_To_Install_Java.html Name=content Marginheight=1 Marginwidth=1> </Frameset> </Html> [ 00_Top_Menu.html ] <Html> <Head>Top Menu</Head> <Body> <Center> <Base target=lower_frame> <Table Border=1 Cellpadding=3 Width=100%> <Tr> <Td Align=Center Bgcolor=#3366FF><A Href=00_Home.html><Font Size=4 Color=White>Home</Font></A></Td> <Td Align=Center Bgcolor=#3366FF><A Href=00_Install_Java.html><Font Size=4 Color=White>Install Java</Font></A></Td> </Tr> </Table> </Center> </Body> </Html> [ 01_Home_Menu.html ] <Html> <Head><Title>Home Menu</Title></Head> <Base Target=content> <Body Bgcolor=#7799DD> <Center> <Table Border=1 Width=100%> <Tr><Td Align=center Bgcolor=#66AAFF><A Href=10_Home_Welcome.html>Welcome</A></Td></Tr> </Table> </Center> </Body> </Html> [ 01_Install_Java_Menu.html ] <Html> <Head><Title>Install Java</Title></Head> <Base Target=content> <Body Bgcolor=#7799DD> <Center> <Table Border=1 Width=100%> <Tr><Td Align=Center Bgcolor=#66AAFF><A Href=10_How_To_Install_Java.html>How To Install Java ?</A></Td></Tr> </Table> </Center> </Body> </Html> [ 10_Home_Welcome.html ] <Html> <Head><Title>NMJava For Software Development</Title></Head> <Body> <Center> <P> <Font Size=5 Color=blue>Welcome To NMJava For Software Development</Font> <P> </Center> </Body> </Html> [ 10_How_To_Install_Java.html ] <Html> <Head> <Title>Install Java</Title> </Head> <Body> <Center> <Br> <Font Size=5 Color=#0022AE><A Href=http://java.com/en/download/index.jsp>How To Install Java ?</A></Font> <Br> <P> <Table Width=90% Cellspacing=5 Cellpadding=5> <Tr><Td><Font Color=#0022AE> You need JRE 6 (Java Runtime Environment) to run the programs on this site.

  • How to set up port forwarding and firewall settings for torrents using Transmsission on Mac OSX 10.5

    - by Liz
    I have picked up bits of advice here and there on the internet and got someway through this tortuous exercise (after it took 18 hours to download the first torrent I tried yesterday - magnet-link for a film). Where I have got stuck is with configuring the firewall on the Netgear Router but I am not sure if I have caused the problem myself by something else I have done configuring the Mac System Preferences for Security or Networking. I have been following the sections of these instructions that seem to apply, although they are written for a different OSX version (don't know which one, but the screen shots do not match what I see) and I am not wanting to set up my Mac as a server and attending to the parts that apply to port forwarding for Netgear rather than LinkSys: http://homepage.mac.com/car1son/static_port_fwd_intro.html I have been trying to follow these instructions: Instructions for DG834, DG834G, DG824M, FR114W, FM114P, FR114P, FR328S, FVL328, FVS328, FVS338, FVX538, FWAG114, FWG114P, or FVS318v3 These routers do port forwarding by assigning port numbers to a "service" associated with the application you want to run. "Rules" are set for particular services. Rules block or allow access, based on various conditions such as the time of day and the name of the service. To Create a New Inbound or Outbound Rule 1. Submit the router's address in an Internet browser. (The default is 192.168.0.1). 2. Enter the router's username and password. 3. From the main menu, click Security > Rules. 4. Click Add for inbound or outbound traffic, as appropriate to the application you are planning to run. 5. Select the Service. The services the router knows about are listed in the drop down. If the service you want is not listed, add it as described in the next section. 6. Select the Action, for example ALLOW always. 7. For Send to LAN Server, enter the IP address of the local server. Note that this is also the IP address the computers on your LAN will access. 8. For WAN User choose Any, or limit access to particular IP addresses. 9. For Log selection it is reasonable to turn logs on, especially at the beginning when you are unsure of the result of the changes you are making. Later, you may want to set logs to "Never" for performance reasons. 10. Click Apply. As noted in user manual for some models: * Consider using the Dynamic DNS feature on the Advanced menu, so that external users can find your network when the DHCP lease is renewed by your ISP. * If your own LAN server uses DHCP, and your IPs change on rebooting, consider using the Reserved IP Address feature in the LAN IP menu. To Add a Service for These Routers 1. Click Security > Services > Add Custom Service. 2. Enter any name you choose for the service. 3. Select whether the service is to use TCP or UDP. If you are unsure, select both. 4. Enter the lowest port number used by the service. 5. Enter the highest port number used. If the service uses only one port number, enter the same number. 6. Click Apply. There is no "Security - Rules" submenu in the Netgear page, so I have been trying to access "Security - Firewall Rules". I can access everthing else in the Netgear settings as Admin but I cannot get the "Firewall Rules" section to open up. (I am not 100% sure I will know exactly what to do if and when I do get it opened up!) I haven't managed to find though searching the internet any instructions that would seem to apply specifically to what I am trying to achieve, so would be very grateful if someone could either point me in the right direction or give me some advice directly. Best wishes, Liz

    Hi this is my code for simple camera application in android .i have copied it from unlocking android e-book . Everything is working fine in emulator but when i am installing it in device the camera preview is working only in landscape mode. I have tried many thing but could not find any solution. Please see the code below and if you have any solution for it than it will be helpful to me. this is the code....... public class SimpleCamera extends Activity implements SurfaceHolder.Callback { private Camera camera; private boolean isPreviewRunning = false; private SimpleDateFormat timeStampFormat = new SimpleDateFormat("yyyyMMddHHmmssSS"); private SurfaceView surfaceView; private SurfaceHolder surfaceHolder; private Uri targetResource = Media.EXTERNAL_CONTENT_URI; public void onCreate(Bundle icicle) { super.onCreate(icicle); Window window = getWindow(); window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); getWindow().setFormat(PixelFormat.TRANSLUCENT); setContentView(R.layout.main); surfaceView = (SurfaceView)findViewById(R.id.surface); surfaceHolder = surfaceView.getHolder(); surfaceHolder.getSurface(); // Surface.setOrientation(Display.DEFAULT_DISPLAY,Surface.ROTATION_180); //didn't work at all surfaceHolder.addCallback(this); surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public boolean onCreateOptionsMenu(android.view.Menu menu) { MenuItem item = menu.add(0, 0, 0, "View Pictures"); item.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() { public boolean onMenuItemClick(MenuItem item) { Intent intent = new Intent(Intent.ACTION_VIEW, targetResource); startActivity(intent); return true; } }); return true; } protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); } Camera.PictureCallback mPictureCallbackRaw = new Camera.PictureCallback() { public void onPictureTaken(byte[] data, Camera c) { camera.startPreview(); } }; Camera.ShutterCallback mShutterCallback = new Camera.ShutterCallback() { public void onShutter() { } }; public boolean onKeyDown(int keyCode, KeyEvent event) { ImageCaptureCallback camDemo = null; if(keyCode == KeyEvent.KEYCODE_DPAD_CENTER) { try { String filename = timeStampFormat.format(new Date()); ContentValues values = new ContentValues(); values.put(Media.TITLE, filename); values.put(Media.DESCRIPTION, "Image from Android Emulator"); Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values); camDemo = new ImageCaptureCallback( getContentResolver().openOutputStream(uri)); } catch(Exception ex ){ } } if (keyCode == KeyEvent.KEYCODE_BACK) { return super.onKeyDown(keyCode, event); } if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) { camera.takePicture(mShutterCallback, mPictureCallbackRaw, camDemo); return true; } return false; } protected void onResume() { Log.e(getClass().getSimpleName(), "onResume"); super.onResume(); } protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); } protected void onStop() { super.onStop(); } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { if (isPreviewRunning) { camera.stopPreview(); } Camera.Parameters p = camera.getParameters(); p.setPreviewSize(w,h); //p.set("rotation","90"); // it didn't work //P.setRotation(90); // only work in 2.0 or later SDK but i am using 1.5 camera.setParameters(p); try { camera.setPreviewDisplay(holder); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } camera.startPreview(); isPreviewRunning = true; } public void surfaceCreated(SurfaceHolder holder) { camera = Camera.open(); } public void surfaceDestroyed(SurfaceHolder holder) { camera.stopPreview(); isPreviewRunning = false; camera.release(); } } any help will be appreciated..

  • drupal_get_form is not passing along node array

    - by ElectronicBlacksmith
    I have not been able to get drupal_get_form to pass on the node data. Code snippets are below. The drupal_get_form documentation (api.drupal.org) states that it will pass on the extra parameters. I am basing the node data not being passed because (apparently) $node['language'] is not defined in hook_form which causes $form['qqq'] not to be created and thus the preview button shows up. My goal here is that the preview button show up using path "node/add/author" but doesn't show up for "milan/author/add". Any alternative methods for achieving this goal would be helpful but the question I want answered is in the preceding paragraph. Everything I've read indicates that it should work. This menu item $items['milan/author/add'] = array( 'title' = 'Add Author', 'page callback' = 'get_author_form', 'access arguments' = array('access content'), 'file' = 'author.pages.inc', ); calls this code function get_author_form() { //return node_form(NULL,NULL); //return drupal_get_form('author_form'); return author_ajax_form('author'); } function author_ajax_form($type) { global $user; module_load_include('inc', 'node', 'node.pages'); $types = node_get_types(); $type = isset($type) ? str_replace('-', '_', $type) : NULL; // If a node type has been specified, validate its existence. if (isset($types[$type]) && node_access('create', $type)) { // Initialize settings: $node = array('uid' = $user-uid, 'name' = (isset($user-name) ? $user-name : ''), 'type' = $type, 'language' = 'bbb','bbb' = 'TRUE'); $output = drupal_get_form($type .'_node_form', $node); } return $output; } And here is the hook_form and hook_form_alter code function author_form_author_node_form_alter(&$form, &$form_state) { $form['author']=NULL; $form['taxonomy']=NULL; $form['options']=NULL; $form['menu']=NULL; $form['comment_settings']=NULL; $form['files']=NULL; $form['revision_information']=NULL; $form['attachments']=NULL; if($form["qqq"]) { $form['buttons']['preview']=NULL; } } function author_form(&$node) { return make_author_form(&$node); } function make_author_form(&$node) { global $user; $type = node_get_types('type', $node); $node = author_make_title($node); drupal_set_breadcrumb(array(l(t('Home'), NULL), l(t($node-title), 'node/' . $node-nid))); $form['authorset'] = array( '#type' = 'fieldset', '#title' = t('Author'), '#weight' = -50, '#collapsible' = FALSE, '#collapsed' = FALSE, ); $form['author_id'] = array( '#access' = user_access('create pd_recluse entries'), '#type' = 'hidden', '#default_value' = $node-author_id, '#weight' = -20 ); $form['authorset']['last_name'] = array( '#type' = 'textfield', '#title' = t('Last Name'), '#maxlength' = 60, '#default_value' = $node-last_name ); $form['authorset']['first_name'] = array( '#type' = 'textfield', '#title' = t('First Name'), '#maxlength' = 60, '#default_value' = $node-first_name ); $form['authorset']['middle_name'] = array( '#type' = 'textfield', '#title' = t('Middle Name'), '#maxlength' = 60, '#default_value' = $node-middle_name ); $form['authorset']['suffix_name'] = array( '#type' = 'textfield', '#title' = t('Suffix Name'), '#maxlength' = 14, '#default_value' = $node-suffix_name ); $form['authorset']['body_filter']['body'] = array( '#access' = user_access('create pd_recluse entries'), '#type' = 'textarea', '#title' = 'Describe Author', '#default_value' = $node-body, '#required' = FALSE, '#weight' = -19 ); $form['status'] = array( '#type' = 'hidden', '#default_value' = '1' ); $form['promote'] = array( '#type' = 'hidden', '#default_value' = '1' ); $form['name'] = array( '#type' = 'hidden', '#default_value' = $user-name ); $form['format'] = array( '#type' = 'hidden', '#default_value' = '1' ); // NOTE in node_example there is some addition code here not needed for this simple node-type $thepath='milan/author'; if($_REQUEST["theletter"]) { $thepath .= "/" . $_REQUEST["theletter"]; } if($node['language']) { $thepath='milan/authorajaxclose'; $form['qqq'] = array( '#type' = 'hidden', '#default_value' = '1' ); } $form['#redirect'] = $thepath; return $form; } That menu path coincides with this theme (PHPTemplate)

  • fonts mac vs pc

    - by Kieran
    Hi all hope your having a good day/evening. Simple question, but maybe not so simple to answer. I have an unordered list, which i am using as a menu. The list items are floated right and sized due to an anchor tag inside them with a roll over. The last element is given a specific size to suck up any extra space. See the code snippits bellow. css ul.mainNav { width: 970px; display:block; background:black; clear:both; overflow:hidden;} ul.mainNav li { float: left; height:29px;} ul.mainNav li a { display: block; padding:7px 19px; color:#ffffff; background-color:#000; font-weight:bold; text-decoration:none; font-size:13px; } ul.mainNav li a:hover, ul.mainNav li a.selected { background-color:#ffff00; color:#000; } ul.mainNav li a.last{ text-align:center; padding: 7px 19px; width:58px;} html <ul class="mainNav" id="mainNav"> <li><a href="/Default.aspx">home</a></li> <li><a href="/About/">about</a></li> <li><a href="/News/">news</a></li> <li><a href="/Enter/Registration.aspx">enter SOYA 2010</a></li> <li><a href="/Categories/Film.aspx">categories</a></li> <li><a href="/Mentors/janChapman.aspx">mentors</a></li> <li><a href="/PastWinners/">past winners</a></li> <li><a href="/Awards/">awards nights</a></li> <li><a href="/Support/" class="last">contact</a></li> </ul> It is containted in a <div style="margin:0 auto;">...</div> to center on the menu on screen Now my problem is: On PC; firefox/ Safari /IE /Chrome are all displaying correctly. Take the same code to a Mac; Safari/ firefox are displaying the menu to be too short and the only thing i can point to is that the fonts may be smaller in widths. The width is currently set to 970px. My question is: How can i get it to display at the same widths without specifying exact widths for each list item? Any help would be appreciated. If my structure is wrong or it is just a mac thing that i will never solve(hope not). Cheers, KJ

  • Update to Easy Slider 1.7 made all my JQuery code stop working.

    - by Anders H
    I'm pretty novice as a JQuery user goes. I've got some experience implementing different plugins but would be lost trying to customize my own. I can't share the exact site details with you due to a NDA, so I hope someone can give me a little help. I've got a project due today (Just HTML/CSS/JQuery). It has a lightbox, show/hide login menu and a slider is Easy Slider 1.5. Everything was working together, until I attempted to update to Easy Slider 1.7 (see link on same page, I'm too new to post more than 1 link). When I did so, JQuery stopped working for all the plugins. I've attempted to revert back to the original state, by undoing my work (didn't do much), ad JQuery remains broken. Firebug Error Console shared no errors. I can't find anything in the code no matter how hard I look at it. Can anyone help me troubleshoot this JQuery problem? Delivery is supposed to be tonight for the project.

  • WPF Issues with Control Layout

    - by Brett Powell
    I am making an application that connects to our billing software using its API, and I am running into a few issues getting the layout working properly. I want to make it so that when one of the expanders is minimized, the other window fills the gap, and when it is expanded again the other expander goes back to where it was. Right now when the arrow is clicked on one, there is just an empty gap. I used a DockPanel as the parent which I assumed would automatically do this, but it isn't working. Second question, is there a way to make these areas resizable? I don't want to try and get too frisky with allowing the user to undock the menus (don't even know if that is possible with just straight WPF) but it would be nice if they could change the width/height of them. Also, just a newbie question to C#, but what is the equivalent of a C++ header file? It looks like you just use .cs files, but I am not sure. I want to extract all of my functions that pull the data from the billing software and put them into a different file to clean up the code. Here is my XAML... <Window x:Class="WpfApplication3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Billing Management" Height="550" Width="754" xmlns:shared="http://schemas.actiprosoftware.com/winfx/xaml/shared" WindowStartupLocation="CenterScreen" WindowStyle="ThreeDBorderWindow"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="22" /> <RowDefinition /> </Grid.RowDefinitions> <Menu Height="22" Name="menu1" Margin="0" HorizontalAlignment="Stretch" VerticalAlignment="Top" HorizontalContentAlignment="Left" IsEnabled="True" IsMainMenu="True"> <MenuItem Header="_File"> <MenuItem Header="_Open" /> <MenuItem Header="_Close" /> <Separator/> <MenuItem Header="_Exit" /> </MenuItem> </Menu> <TabControl Name="tabControl1" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" BorderThickness="1" Padding="0" TabStripPlacement="Bottom" UseLayoutRounding="False" FlowDirection="LeftToRight" Grid.Row="1"> <TabItem Header="Main" Name="tabItem1" Margin="0"> <DockPanel Name="dockPanel1" LastChildFill="True"> <ListBox Height="100" Name="listBox3" DockPanel.Dock="Top" /> <ListBox Name="listBox4" Width="200" DockPanel.Dock="Right" /> <DockPanel Height="Auto" Name="dockPanel2" Width="Auto" VerticalAlignment="Stretch" LastChildFill="True"> <shared:AnimatedExpander Header="Staff Online" Width="200" Name="expanderStaffOnline" IsExpanded="True" Height="194" BorderThickness="0" DockPanel.Dock="Top" VerticalContentAlignment="Stretch"> <ListBox Name="listboxStaffOnline" Width="Auto" Height="Auto" Margin="0" VerticalAlignment="Stretch" Loaded="listboxStaffOnline_Loaded" /> </shared:AnimatedExpander> <shared:AnimatedExpander Header="Test Menu 2" Height="Auto" Name="animatedExpander1" BorderThickness="1" Margin="0,0,0,0" IsExpanded="True" VerticalContentAlignment="Stretch"> <ListBox Height="Auto" HorizontalAlignment="Stretch" Name="listBox6" VerticalAlignment="Stretch" Margin="0" BorderThickness="1" /> </shared:AnimatedExpander> </DockPanel> <ListBox Height="100" Name="listboxAdminLogs" DockPanel.Dock="Bottom" Loaded="listboxAdminLogs_Loaded" /> <ListBox Name="listBox5" /> </DockPanel> </TabItem> <TabItem Header="Support" Name="tabItem2" Margin="0"> </TabItem> <TabItem Header="Clients" /> <TabItem Header="Billing" /> <TabItem Header="Orders" /> </TabControl> </Grid> </Window>

  • tkinter frame does not show on startup

    - by Jzz
    this is my first question on SO, so correct me please if I make a fool of myself. I have this fairly complicated python / Tkinter application (python 2.7). On startup, the __init__ loads several frames, and loads a database. When that is finished, I want to set the application to a default state (there are 2 program states, 'calculate' and 'config'). Setting the state of the application means that the appropriate frame is displayed (using grid). When the program is running, the user can select a program state in the menu. Problem is, the frame is not displayed on startup. I get an empty application (menu bar and status bar are displayed). When I select a program state in the menu, the frame displays as it should. Question: What am I doing wrong? Should I update idletasks? I tried, but no result. Anything else? Background: I use the following to switch program states: def set_program_state(self, state): '''sets the program state''' #try cleaning all the frames: try: self.config_frame.grid_forget() except: pass try: self.tidal_calculations_frame.grid_forget() except: pass try: self.tidal_grapth_frame.grid_forget() except: pass if state == "calculate": print "Switching to calculation mode" self.tidal_calculations_frame.grid() #frame is preloaded self.tidal_calculations_frame.fill_data(routes=self.routing_data.routes, deviations=self.misc_data.deviations, ship_types=self.misc_data.ship_types) self.tidal_grapth_frame.grid() self.program_state = "calculate" elif state == "config": print "Switching to config mode" self.config_frame = GUI_helper.config_screen_frame(self, self.user) #load frame first (contents depend on type of user) self.config_frame.grid() self.program_state = "config" I understand that this is kind of messy to read, so I simplified things for testing, using this: def set_program_state(self, state): '''sets the program state''' #try cleaning all the frames: try: self.testlabel_1.grid_forget() except: pass try: self.testlabel_2.grid_forget() except: pass if state == "calculate": print "switching to test1" self.testlabel_1 = tk.Label(self, text="calculate", borderwidth=1, relief=tk.RAISED) self.testlabel_1.grid(row=0, sticky=tk.W+tk.E) elif state == "config": print "switching to test1" self.testlabel_2 = tk.Label(self, text="config", borderwidth=1, relief=tk.RAISED) self.testlabel_2.grid(row=0, sticky=tk.W+tk.E) But the result is the same. The frame (or label in this test) is not displayed at startup, but when the user selects the state (calling the same function) the frame is displayed. UPDATE the sample code in the comments (thanks for that!) pointed me in another direction. Further testing revealed (what I think) the cause of the problem. Disabling the display of the status bar made the program work as expected. Turns out, I used pack to display the statusbar and grid to display the frames. And they are in the same container, so problems arise. I fixed that by using only pack inside the main container. But the same problem is still there. This is what I use for the statusbar: self.status = GUI_helper.StatusBar(self.parent) self.status.pack(side=tk.BOTTOM, fill=tk.X) And if I comment out the last line (pack), the config frame loads on startup, as per this line: self.set_program_state("config") But if I let the status bar pack inside the main window, the config frame does not show. Where it does show when the user asks for it (with the same command as above).

  • Problem with sending out variable to serial port using api JAVA

    - by sjaakensjon
    We are developing a java program for school. But we are experiencing problems with sending out a variable created by 3 sliders. The idea is that we have 3 sliders. One slider for every color. Red green and blue. The variable has to have a value between 0 and 255. Everytime the value of the slider changes is has to send a variable for the channel, that value is 1, 2 ,3. And after that it has to send the value of the slider through the serial port. Could you please help us out by creating an example program? Below is our code so far. Thanks in advance. Sjaak package main; import javax.swing.*; import javax.swing.event.*; import java.awt.*; import app.Com; import app.Parameters; public class menu{ JSlider sliderblauw; JLabel hoeveelblauw; JLabel blauw; JLabel rood; JSlider sliderrood; JLabel hoeveelrood; JLabel groen; JLabel hoeveelgroen; JSlider slidergroen; public menu(){ Frame venster = new JFrame("Color control"); JPanel blauwinstel = new JPanel(); ((JFrame) venster).setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); venster.setSize(500, 500); venster.setVisible(true); sliderblauw = new JSlider(JSlider.VERTICAL, 0, 255, 0); sliderblauw.addChangeListener(new veranderingblauw()); hoeveelblauw = new JLabel ("0"); blauwinstel.add(sliderblauw); blauwinstel.add(hoeveelblauw); venster.add(blauwinstel, BorderLayout.WEST); sliderblauw.setMajorTickSpacing(10); sliderblauw.setPaintTicks(true); JPanel roodinstel = new JPanel(); sliderrood = new JSlider(JSlider.VERTICAL, 0, 255, 0); sliderrood.addChangeListener(new veranderingrood()); hoeveelrood = new JLabel ("0"); roodinstel.add(sliderrood); roodinstel.add(hoeveelrood); venster.add(roodinstel, BorderLayout.EAST); sliderrood.setMajorTickSpacing(10); sliderrood.setPaintTicks(true); JPanel groeninstel = new JPanel(); slidergroen = new JSlider(JSlider.VERTICAL, 0, 255, 0); slidergroen.addChangeListener(new veranderinggroen()); hoeveelgroen = new JLabel ("0"); groeninstel.add(slidergroen); groeninstel.add(hoeveelgroen); venster.add(groeninstel, BorderLayout.CENTER); slidergroen.setMajorTickSpacing(10); slidergroen.setPaintTicks(true); } public class veranderingblauw implements ChangeListener{ public void stateChanged(ChangeEvent ce){ int value = sliderblauw.getValue(); String waarde_blauw = Integer.toString(value); hoeveelblauw.setText(waarde_blauw); }} public class veranderingrood implements ChangeListener{ public void stateChanged(ChangeEvent ce){ int value = sliderrood.getValue(); String waarde_rood = Integer.toString(value); hoeveelrood.setText(waarde_rood); }} public class veranderinggroen implements ChangeListener{ public void stateChanged(ChangeEvent ce){ int value = slidergroen.getValue(); String waarde_groen = Integer.toString(value); hoeveelgroen.setText(waarde_groen); }} public static void main( String[] args) { new menu(); } }

  • How to properly use the .each() command in jQuery

    - by sadmicrowave
    I have a script that checks the class (integer) of a , runs a switch statement to change that integer value to text and appends the text to another in the same listitem tag. I use the .each() function because each listitem starts with class=_[user ID] -- each user can have up to 5 entries.. Enough explaining -- heres the code: <HTML> <li class='_44074'><div class='_12' style='width:380px;'><div style='width:60px; float:left;'>1st</div><div class='verify-type' style='float:left; width:160px;'></div><div style='float:left; width:120px;'>04/26/10 07:29 AM</div></div></li> <li class='_44074'><div class='_6' style='width:380px;'><div style='width:60px; float:left;'>2nd</div><div class='verify-type' style='float:left; width:160px;'></div><div style='float:left; width:120px;'>04/23/10 03:29 PM</div></div></li> <li class='_44074'><div class='_12' style='width:380px;'><div style='width:60px; float:left;'>3rd</div><div class='verify-type' style='float:left; width:160px;'></div><div style='float:left; width:120px;'>04/23/10 03:18 PM</div></div></li> <li class='_44074'><div class='_2' style='width:380px;'><div style='width:60px; float:left;'>4th</div><div class='verify-type' style='float:left; width:160px;'></div><div style='float:left; width:120px;'>04/23/10 02:28 PM</div></div></li> </HTML> when I use the .each() function to scan through each of the listitems begining with the entered user id it only finds the first value (in this case _12) and applies that to all the entries; instead of finding _12, _6, _12, _2 it finds _12, _12, _12, _12...here is the java: $("div#history-menu div#history-text li." + valueid).each(function(){ valueid = $("div#center-box input").val(); checkedvalue=""; checkedvalue = $("div#history-menu div#history-text li." + valueid + " div").attr('class'); switch(checkedvalue){ case '_2':lcCheckedMessage = "Shoes"; break; case '_4':lcCheckedMessage = "Shoe Straps"; break; case '_6':lcCheckedMessage = "Shoes & Shoe Straps"; break; case '_8':lcCheckedMessage = "Wrist Straps"; break; case '_10':lcCheckedMessage = "Shoes & Wrist Strap"; break; case '_12':lcCheckedMessage = "Shoe Straps & Wrist Strap"; break; }; $("div#history-menu div#history-text li." + valueid + " ." + checkedvalue + " .verify-type").text(lcCheckedMessage); });

  • not able to style a ul inside a nav tag

    - by user1831677
    I am trying to make a nav menu for my website and have been using http://www.onextrapixel.com/2011/06/03/how-to-create-a-horizontal-dropdown-menu-with-html-css-and-jquery/ as a guide. It has worked fine but as soon as I try to add ( id="coolMenu" ) to the nav tag it stops working. I took it away from the ul tag and added it to the nav tag and it no longer works. It does not display anything at all. What am in doing wrong? Thanks. html code below: <nav id="coolMenu"> <ul> <li><a href="#">Lorem</a></li> <li><a href="#">Mauricii</a></li> <li> <a href="#">Periher</a> <ul class="noJS"> <li><a href="#">Hellenico</a></li> <li><a href="#">Genere</a></li> <li><a href="#">Indulgentia</a></li> </ul> </li> <li><a href="#">Tyrio</a></li> <li><a href="#">Quicumque</a></li> </ul> </nav> css below: /* Structure ------------------------------------------*/ #coolMenu, #coolMenu ul { list-style: none; } #coolMenu { float: left; } #coolMenu > li { float: left; } #coolMenu li a { display: block; height: 2em; line-height: 2em; padding: 0 1.5em; text-decoration: none; } #coolMenu ul { position: absolute; display: none; z-index: 999; } #coolMenu ul li a { width: 80px; } #coolMenu li:hover ul.noJS { display: block; } /* Main menu ------------------------------------------*/ #coolMenu { font-family: Arial; font-size: 12px; background: #2f8be8; } #coolMenu > li > a { color: #fff; font-weight: bold; } #coolMenu > li:hover > a { background: #f09d28; color: #000; } /* Submenu ------------------------------------------*/ #coolMenu ul { background: #f09d28; } #coolMenu ul li a { color: #000; } #coolMenu ul li:hover a { background: #ffc97c; }
