  • IE6 "frame" layout with 100% height and scrollbars

    - by Joe
    I want to achieve a simple "frame" layout with fixed header, fixed left navigation area, and a main content area that fills 100% of the remainder of the viewport with scrollbars if necessary. My best attempt is below - but when I add enough content to the main div to force scrolling, I see that the scrollbar extends below the bottom of the viewport. What am I doing wrong? Or what is IE6 doing wrong and how can I fix it? NB please don't recommend using a more recent browser - I'd love to but can't. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title></title> <style type="text/css"> html, body { height:100%; margin:0; padding:0; overflow:hidden; } div { border:0; margin:0; padding:0; } div#top { background-color:#dddddd; height:100px; } div#left { background-color:#dddddd; float:left; width:120px; height:100%; overflow:hidden; } div#main { height:100%; overflow:auto; } </style> </head> <body> <div id="top">Title</div> <div id="left">LeftNav</div> <div id="main"> Content <p> Lorem ipsum ... </p> ... repeated several times ... </div> </body> </html>

  • Keyboard selecting nested li's with jquery

    - by Joel
    I have a load of nested <ul>'s and <li>'s and I would like to be able to have a hover / selected class on an <li>, and use the keyboard up and down buttons to select up and down on the <li>s.. however they are nested and need to jump across <ul>s if necessary. For instance: <ul> <li class='cat'> cat 1 <ul> <li class='hover'>item 1</li> <li>item 2</li> <li>item 3</li> <li>item 4</li> </ul> </li> <li class='cat'> cat 2 <ul> <li>item 5</li> <li>item 6</li> <li>item 7</li> <li>item 8</li> </ul> <ul class='subcat'> <li class='cat'> Cat 3 <ul> <li>item 9</li> <li>item 10</li> <li>item 11</li> <li>item 12</li> </ul> </li> </ul> </li> <li class='cat'> cat 4 <ul> <li>item 13</li> <li>item 14</li> <li>item 15</li> <li>item 16</li> </ul> </li> </ul> As I press the down key I wish the items to be selected in numerical order (they do not have numerical order IDs and sometimes some of them are hidden so they should be ignored. But it needs to go to the next <li> that isn't a category and set that as hover.

  • Title: Using Window Handle to disable Mouse clicks and Keyboard Inputs using Pinvoke c#

    I need to disable the Mouse Clicks, Mouse movement and Keyboard Inputs for a specific windows for a Kiosk application. Is it Feasible in C# ?

  • How to occupy all the space in a div when working with min-height header / footer

    - by javacoder
    I believe this is a beginner's CSS question. I am utilizing the method described in http://www.xs4all.nl/~peterned/examples/csslayout1.html to fix a header to the top and a footer to the bottom. What I'd like to achieve now is two columns inside the content div. A left one of 200px and a right one that takes up the rest of the width. Unfortunately, I can't get the left and right divs to display correctly: they just don't grow vertically, and if I make the right div "width: 100%" it positions itself underneath the left one. What is the trick to make the left and right div take up all the space within the content div? The layout1.css is the original one. I just added two entries: #left and #right layout1.css: /** * 100% height layout with header and footer * ---------------------------------------------- * Feel free to copy/use/change/improve */ html,body { margin: 0; padding: 0; height: 100%; /* needed for container min-height */ background: gray; font-family: arial, sans-serif; font-size: small; color: #666; } h1 { font: 1.5em georgia, serif; margin: 0.5em 0; } h2 { font: 1.25em georgia, serif; margin: 0 0 0.5em; } h1,h2,a { color: orange; } p { line-height: 1.5; margin: 0 0 1em; } div#container { position: relative; /* needed for footer positioning*/ margin: 0 auto; /* center, not in IE5 */ width: 750px; background: #f0f0f0; height: auto !important; /* real browsers */ height: 100%; /* IE6: treaded as min-height*/ min-height: 100%; /* real browsers */ } div#header { padding: 1em; background: #ddd url("../csslayout.gif") 98% 10px no-repeat; border-bottom: 6px double gray; } div#header p { font-style: italic; font-size: 1.1em; margin: 0; } div#content { padding: 1em 1em 5em; /* bottom padding for footer */ } div#content p { text-align: justify; padding: 0 1em; } div#footer { position: absolute; width: 100%; bottom: 0; /* stick to bottom */ background: #ddd; border-top: 6px double gray; } div#footer p { padding: 1em; margin: 0; } // added the following: div#left { border: 1px solid red; width: 200px; float: left; min-height: 100%; height: 100%; padding-left: 10px; margin-right: 10px; } div#right { border: 1px solid blue; float: left; min-height: 100%; height: 100%; padding-left: 10px; margin-right: 10px; } layout.html: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>CSS Layout - 100% height</title> <link rel="stylesheet" type="text/css" href="layout1.css" /> </head> <body> <div id="container"> <div id="header"> <h1>header</h1> </div> <div id="content"> <div id="left"> left column </div> <div id="right"> right column </div> </div> <div id="footer"> <p> footer </p> </div> </div> </body>

  • Listfield layout question - blackberry

    - by Kai
    I'm having an interesting anomaly when displaying a listfield on the blackberry simulator: The top item is the height of a single line of text (about 12 pixels) while the rest are fine. Does anyone know why only the top item is being drawn this way? Also, when I add an empty venue in position 0, it still displays the first actual venue this way (item in position 1). Not sure what to do. Thanks for any help. The layout looks like this: ----------------------------------- | *part of image* | title | ----------------------------------- | | title | | * full image * | address | | | city, zip | ----------------------------------- The object is called like so: listField = new ListField( venueList.size() ); listField.setCallback( this ); listField.setSelectedIndex(-1); _middle.add( listField ); Here is the drawListRow code: public void drawListRow( ListField listField, Graphics graphics, int index, int y, int width ) { listField.setRowHeight(90); Hashtable item = (Hashtable) venueList.elementAt( index ); String venue_name = (String) item.get("name"); String image_url = (String) item.get("image_url"); String address = (String) item.get("address"); String city = (String) item.get("city"); String zip = (String) item.get("zip"); EncodedImage img = null; try { String filename = image_url.substring( image_url.indexOf("crop/") + 5, image_url.length() ); FileConnection fconn = (FileConnection) Connector.open( "file:///SDCard/Blackberry/project1/" + filename, Connector.READ); if ( !fconn.exists() ) { } else { InputStream input = fconn.openInputStream(); byte[] data = new byte[(int)fconn.fileSize()]; input.read(data); input.close(); if(data.length > 0) { EncodedImage rawimg = EncodedImage.createEncodedImage(data, 0, data.length); int dw = Fixed32.toFP(Display.getWidth()); int iw = Fixed32.toFP(rawimg.getWidth()); int sf = Fixed32.div(iw, dw); img = rawimg.scaleImage32(sf * 4, sf * 4); } else { } } } catch(IOException ef) { } graphics.drawText( venue_name, 140, y, 0, width ); graphics.drawText( address, 140, y + 15, 0, width ); graphics.drawText( city + ", " + zip, 140, y + 30, 0, width ); if(img != null) { graphics.drawImage(0, y, img.getWidth(), img.getHeight(), img, 0, 0, 0); } }

  • Firefox can not layout nested tables properly?

    - by ooplidi
    I want to implement a collapsible menu. I plan to use table component to simulate a menu, and nest a sub table into a table cell to simulate a sub menu. Below is my code, it works as expected in IE, Chrome and Safari, but it doesn't work well in Firefox: <html> <body> <div id="menu" style="position:absolute; left:150px; top:100px; z-index:1"> <table width="200px" height="90" border=1 cellpadding="0" cellspacing="0"> <tr> <td colspan=2>Money</td> </tr> <tr> <td colspan=2>Tool</td> </tr> <tr> <td>Food <table style="position:absolute; left:200px; top:60px; z-index:1" width="200px" height="60px" border="1" cellpadding="0" cellspacing="0"> <tr> <td>Cookie</td> </tr> <tr> <td>Fruit <table style="position:absolute; left:200px; top:30px; z-index:1" width="200px" height="60px" border="1" cellpadding="0" cellspacing="0"> <tr> <td>Apple</td> </tr> <tr> <td>Banana</td> </tr> </table> </td> </tr> </table> </td> </tr> </table> </div> </body> </html> It seems that Firefox think the "left" and "top" attribute for the level 3 menu is relative to the level 1 menu, so it layout the level 3 menu incorrectly. Other browsers will calculate the offset base on the level 2 menu, that works as expected. Is it a bug in Firefox? If so how can I work around it? I want my code to have the same behavior in all major browsers.

  • Not seeing Sync Block in Object Layout

    - by bob-bedell
    It's my understanding the all .NET object instances begin with an 8 byte 'object header': a synch block (4 byte pointer into a SynchTableEntry table), and a type handle (4 byte pointer into the types method table). I'm not seeing this in VS 2010 RC's (CLR 4.0) debugger memory windows. Here's a simple class that will generate a 16 byte instance, less the object header. class Program { short myInt = 2; // 4 bytes long myLong = 3; // 8 bytes string myString = "aString"; // 4 byte object reference // 16 byte instance static void Main(string[] args) { new Program(); return; } } An SOS object dump tells me that the total object size is 24 bytes. That makes sense. My 16 byte instance plus an 8 byte object header. !DumpObj 0205b660 Name: Offset_Test.Program MethodTable: 000d383c EEClass: 000d13f8 Size: 24(0x18) bytes File: C:\Users\Bob\Desktop\Offset_Test\Offset_Test\bin\Debug\Offset_Test.exe Fields: MT Field Offset Type VT Attr Value Name 632020fc 4000001 10 System.Int16 1 instance 2 myInt 632050d8 4000002 4 System.Int64 1 instance 3 myLong 631fd2b8 4000003 c System.String 0 instance 0205b678 myString Here's the raw memory: 0x0205B660 000d383c 00000003 00000000 0205b678 00000002 ... And here are some annotations: offset 0 000d383c ;TypeHandle (pointer to MethodTable), 4 bytes offset 4 00000003 00000000 ;myLong, 8 bytes offset 12 0205b678 ;myString, 4 byte reference to address of "myString" on GC Heap offset 16 00000002 ;myInt, 4 bytes My object begins a address 0x0205B660. But I can only account for 20 bytes of it, the type handle and the instance fields. There is no sign of a synch block pointer. The object size is reported as 24 bytes, but the debugger is showing that it only occupies 20 bytes of memory. I'm reading Drill Into .NET Framework Internals to See How the CLR Creates Runtime Objects, and expected the first 4 bytes of my object to be a zeroed synch block pointer, as shown in Figure 8 of that article. Granted, this is an article about CLR 1.1. I'm just wondering if the difference between what I'm seeing and what this early article reports is a change in either the debugger's display of object layout, or in the way the CLR lays out objects in versions later than 1.1. Anyway, can anyone account for my 4 missing bytes?

  • Layout problem: scrollview inside a table, inside a custom dialog

    - by Sean
    I have a layout problem which I can't fix. I've looked through many posts on here, and mine seems to be unique enough to post a question. I've created a custom Dialog which programmatically creates a 3 row table. The top and bottom rows have text, while the middle row contains a ScrollView, which contains a LinearLayout. That LinearLayout then contains some number of views (TextView in this example). Since I'm doing this programmatically, see the XML pseudocode below, and the actual code below that. What I would like to happen, is that when the height of the contained content in the LinearLayout gets too big, the ScrollView does its job, and the header and footer TextView's are always visible. The problem is that when the dialog gets big enough, the ScrollView appears to take over the whole dialog, and my footer TextView disappears off the screen. What can I do to make sure the footer TextView never disappears, but the ScrollView can still function? See the following image links: Footer visible on the left, gone on the right: http://img690.imageshack.us/i/screenshotss.png/ <TableLayout> <TableRow> <TextView> </TableRow> <TableRow> <ScrollView> <LinearLayout> <TextView/> <TextView/> <TextView/> ... </LinearLayout> </ScrollView> </TableRow> <TableRow> <TextView> </TableRow> </TableLayout> Here's the code: public class DialogScrollTest extends Dialog { public DialogScrollTest(Context ctx){ super(ctx); setTitle(""); requestWindowFeature(Window.FEATURE_NO_TITLE); TableLayout table = new TableLayout(ctx); TableRow row; TextView text; row = new TableRow(ctx); { text = new TextView(ctx); text.setText("TestTop"); row.addView(text); } table.addView(row); row = new TableRow(ctx); { ScrollView scroll = new ScrollView(ctx); { LinearLayout linear = new LinearLayout(ctx); linear.setOrientation(LinearLayout.VERTICAL); for(int t=0; t<32; ++t){ text = new TextView(ctx); text.setText("TestScroll"); linear.addView(text); } scroll.addView(linear); } row.addView(scroll); } table.addView(row); row = new TableRow(ctx); { text = new TextView(ctx); text.setText("TestBottom"); row.addView(text); } table.addView(row); this.setContentView(table); } }

  • Dynamically sized UIWebView in a UITableViewCell with auto layout - constraint violation

    - by Orion Edwards
    I've got a UITableViewCell which contains a UIWebView. The table view cell adjusts it's height depending on the web view contents. I've got it all working fine, however when the view loads, I get a constraint violation exception in the debugger (the app continues running and functionally works fine, but I'd like to resolve this exception if possible). How I've got it set up: The TableView sets the cell height like this: -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { if(indexPath.section == 0) { [_topCell layoutIfNeeded]; CGFloat finalHeight = [_topCell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize].height; return finalHeight + 1; } The cell constraints are as follows: Arbitrary 7px offset from the cell's contentView (top) to the webView Web view has arbitrary fixed height constraint of 62px (will expand later once content loads) Arbitrary 8px offset from the webView to the cell's contentView (bottom) in my viewDidLoad, I tell the webView to go and load a URL, and in the webViewDidFinishLoad, I update the web view height constraint, like this -(void)webViewDidFinishLoad:(UIWebView *)webView { CGSize fittingSize = [webView sizeThatFits:CGSizeZero]; // fittingSize is approx 500 [self.tableView beginUpdates]; // Exceptions happen on the following line setting the constant _topCell.webViewHeightConstraint.constant = fittingSize.height; [_topCell layoutSubviews]; [self.tableView endUpdates]; } The exception looks like this: Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) ( "<NSLayoutConstraint:0x10964b250 V:[webView(62)] (Names: webView:0x109664a00 )>", "<NSLayoutConstraint:0x109243d30 V:|-(7)-[webView] (Names: webView:0x109664a00, cellContent:0x1092436f0, '|':cellContent:0x1092436f0 )>", "<NSLayoutConstraint:0x109243f80 V:[webView]-(8)-| (Names: cellContent:0x1092436f0, webView:0x109664a00, '|':cellContent:0x1092436f0 )>", "<NSAutoresizingMaskLayoutConstraint:0x10967c210 h=--& v=--& V:[cellContent(78)] (Names: cellContent:0x1092436f0 )>" ) Will attempt to recover by breaking constraint <NSLayoutConstraint:0x10964b250 V:[webView(62)] (Names: webView:0x109664a00 )> This seems a bit weird. It's implied that the constraint which sets the height of the web view is going to be broken, however the web view does get it's height correctly set, and the tableview renders perfectly well. From my guesses, it looks like the newly increased web view height constraint (it's about 500px after the web view loads) is going to conflict with the <NSAutoresizingMaskLayoutConstraint:0x10967c210 h=--& v=--& V:[cellContent(78)] setting the cell height to 78 (put there by interface builder). This makes sense, however I don't want that cell content to have a fixed height of 78px, I want it to increase it's height, and functionally, it actually does this, just with these exceptions. I've tried setting _topCell.contentView.translatesAutoresizingMaskIntoConstraints = NO; to attempt to remove the NSAutoresizingMaskLayoutConstraint - this stops the exceptions, but then all the other layout is screwed up and the web view is about 10px high in the middle of the table view for no reason. I've also tried setting _topCell.contentView.autoresizingMask |= UIViewAutoresizingFlexibleHeight; in the viewDidLoad to hopefully affect the contentView 78px height constraint, but this has no effect Any help would be much appreciated

    - 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>

  • When to draw/layout child controls in UserControl

    - by Ted Elliott
    I have a list-type UserControl (like a ListBox). The items inside the control are another complex UserControl containing a few other controls (ComboBox, TextBox, etc). I'm wondering what the preferred or best method would be to override to draw/layout the child controls. I basically want to trigger this method any time the list changes. I originally had a RedrawItems method that I just called whenever I needed to redraw which added or removed Controls from the Controls collection. But it was getting triggered too early in the lifecycle of the code from some of the designer code. Now I've switched to overriding OnLayout and doing my stuff there. I call PerformLayout when I want to trigger a redraw, such as when the DataSource property changes or when it fires a changed event. Is OnLayout the best place for this? Here is the code: [ComplexBindingProperties("DataSource")] public partial class CustomList : UserControl { private object _dataSource; private CustomListItem _newRow; public CustomList() { InitializeComponent(); } protected override void OnCreateControl() { base.OnCreateControl(); _newRow = new CustomListItem(); Controls.Add(_newRow); } public object DataSource { get { return _dataSource; } set { bool register = _dataSource != value; if (_dataSource != null && _dataSource != value) { UnregisterDataSource(_dataSource); } _dataSource = value; if (_dataSource != null) RegisterDataSource(_dataSource); PerformLayout(); } } public CustomListItem ItemTemplate { get { return _newRow; } } protected override void OnLayout(LayoutEventArgs e) { base.OnLayout(e); int ctrlCount = this.Controls.AsEnumerable().OfType<CustomListItem>().Count(); ctrlCount--; // subtract 1 for the add row var ds = this.DataSource as System.Collections.IList; int itemCount = ds == null? 0 : ds.Count; int maxCount = Math.Max(ctrlCount,itemCount); if (maxCount == 0) return; this.SuspendLayout(); // temporarily remove the template Controls.RemoveAt(Controls.Count-1); for (int i = 0; i < maxCount; i++) { CustomListItem item; if (i >= itemCount) { Controls.RemoveAt(i); } else { if (i >= ctrlCount) { item = ItemTemplate.Copy(); this.Controls.Add(item); item.Location = new Point(0, item.Height * i); item.TabIndex = i + 1; item.ViewMode = true; } else { item = (CustomListItem) Controls[i]; } item.Data = ds[i]; } } this.Controls.Add(ItemTemplate); ItemTemplate.Location = new Point(0, ItemTemplate.Height * maxCount); ItemTemplate.TabIndex = maxCount + 1; this.ResumeLayout(true); } private void RegisterDataSource(object dataSource) { IBindingList ds = dataSource as IBindingList; if (ds != null) { ds.ListChanged += new ListChangedEventHandler(DataSource_ListChanged); } } void DataSource_ListChanged(object sender, ListChangedEventArgs e) { switch (e.ListChangedType) { case ListChangedType.ItemAdded: PerformLayout(); break; case ListChangedType.ItemChanged: break; case ListChangedType.ItemDeleted: PerformLayout(); break; case ListChangedType.ItemMoved: PerformLayout(); break; case ListChangedType.Reset: PerformLayout(); break; default: break; } } private void UnregisterDataSource(object dataSource) { IBindingList ds = dataSource as IBindingList; if (ds != null) { ds.ListChanged -= new ListChangedEventHandler(DataSource_ListChanged); } } }

  • Delete until previous punctuation mark in Bash

    - by hekevintran
    In Bash, Ctrl + W will erase the last word. Bash considers words to be delimited by spaces. This means that if the cursor is at the end of the string "cd /dir1/dir2/dir3" and you hit Ctrl + W you will be left with "cd ". Is there a Bash shortcut (custom defined is okay) that will leave me with "cd /dir1/dir2/"?

    - by jasondavis
    Sorry if this question exist already, I did some searches but could not find one myself. I am looking for the best programs to copy and paste stuff in windows more easily. So let's say instead of the default copy/paste one item at a time, I could have 5 different paragraphs that could all be pasted somewhere seperately. Hopefully this is not to confusing. Instead of bveing able to paste 1 item I would like to have a list of items that can be pasted or some similar functionality under windows. Please help make me more productive, I frequently need to copy and paste different sets of data. Here is a good exampl, let's say I need to be able to past my email somewhere but on another program or webpage I need to paste my home address.

  • Configuring RealVNC to accept copy/paste on a remote server

    - by AP257
    Hi So, I'm using RealVNC Viewer locally (Mac OSX 10.6) and connecting to a VNC Server on a remote machine (Debian - I'm no Unix expert). I want to be able to copy and paste at the command line, but Ctrl+V, Shift+V and Command+V all do nothing on the remote command line. First question: should I be trying a different combination of keys? Secondly, if it's not that I'm using the wrong combination of keys, how can I configure VNC Server to accept copy and paste? I have 'Share clipboard with VNC Server' checked locally, so I figure it must be a problem on the remote machine. I only have command-line access on the remote machine (though I am root) so I need to configure the option somehow via the command line.

  • Is there a utility that displays hotkeys for the current application?

    - by Alwin
    To speed up my compyuter use I'm trying to use as many hotkeys as possible. But because I'm working in many applications it is really hard to remember all those shortcuts. I'm looking for a program that looks at what application is currently in use by me, and displays a list of possible hotkeys I want to use. Example: I'm writing a document in Word, and the utility program shows a list of hotkeys I could use in Word. With such a program I could learn the shortcut keys much faster. Does such a utility exist?

  • Getting back to Dreamweaver CS4?

    - by Chris_45
    My problem is that I want to assign a keyboardshortcut for Dreamweaver CS4 and I have it like this: "C:\Program Files\Adobe\Adobe Dreamweaver CS4\Dreamweaver.exe" Thats ok so far. But when I press the key it doesn't place itself infront of everything else like Outlook and Visual Studio does for example, instead it blinks in the taskbar, and I have to click there anyway to get back to Dreamweaver. Is there any switch or something I can assign for Dreamweaver to get back AND have it "popup?"

  • How to set a key combination as a browser toolbar shortcut?

    - by Ian Campbell
    For example, I so often clear my browser history with CTRL+SHIFT+DEL. While this is easy enough, I'd like to take it a step further and have a shortcut in my browser's toolbar that when clicked executes the above-mentioned key combination, something like this: Is this directly possible, or would it require creating a plugin? If it would require creating a plugin, how might that be done? p.s. — I'm using Firefox, but it would be awesome if there was a browser-independent solution.

  • Making always-on-top windows follow the same MRU order as other windows

    - by nitro2k01
    Note: I'm using Windows 7 with the classical alt-tab style, ie the registry key AltTabSettings set to 1. I want to use MRU (most recently used) ordering of windows in the alt-tab list. However, because the windows are ordered in the Z order of the windows rather than actual MRU, this sometimes gives a different order after switching from an always-on-top application. Example: I have applications A, B and C open. A is set to always-on-top while the others aren't. A is focused. I now press alt-tab and application B is focused. I now press alt-tab but instead of application A receiving focus, application C does. Since A has a higher Z order, it's now left of application B, despite being the most recently used, and application C is placed right of B and is the one first getting focus by the cursor. To switch to application A, I need to press shift+alt-tab or cycle through all the other open windows. This is annoying when flicking focus back and forth between an always-on-top application and one that isn't always-on-top. Is there a way to make the alt-tab ordering strictly MRU?
