  • Clearing block affects wrong floating

    - by HiveHicks
    I've got two-column layout <div class="left-pane"> Left pane </div> <div class="central-pane"> <div> <ul class="customers-types-tabs"> <li>item 1</li> <li>item 2</li> <li>item 3</li> </ul> </div> <div>Main content</div> </div> and the stylesheet: .left-pane { width: 248px; float: left; background-color: #f6f6f6; border: 1px solid #e6e6e6; padding: 20px 5px; } .central-pane { margin-left: 270px; } .customers-types-tabs li { background-color: #f6f6f6; border: 1px solid #d5d5d5; line-height: 38px; padding: 0 20px; float: left; margin-right: 10px; position: relative; top: 1px; } The problem is that I want "Main content" to appear right below the div with ul inside it (that represents tabs control), but if I set Main content's div's style to clear: both, it appears below the left pane, which is taller than the ul. What should I do to get correct position of main content?

  • java.lang.IllegalArgumentException: View not attached to window manager

    - by alex2k8
    I have an activity that starts AsyncTask and shows progress dialog for the duration of operation. The activity is declared NOT be recreated by rotation or keyboard slide. <activity android:name=".MyActivity" android:label="@string/app_name" android:configChanges="keyboardHidden|orientation" > <intent-filter> </intent-filter> </activity> Once task completed, I dissmiss dialog, but on some phones (framework: 1.5, 1.6) such error is thrown: java.lang.IllegalArgumentException: View not attached to window manager at android.view.WindowManagerImpl.findViewLocked(WindowManagerImpl.java:356) at android.view.WindowManagerImpl.removeView(WindowManagerImpl.java:201) at android.view.Window$LocalWindowManager.removeView(Window.java:400) at android.app.Dialog.dismissDialog(Dialog.java:268) at android.app.Dialog.access$000(Dialog.java:69) at android.app.Dialog$1.run(Dialog.java:103) at android.app.Dialog.dismiss(Dialog.java:252) at xxx.onPostExecute(xxx$1.java:xxx) My code is: final Dialog dialog = new AlertDialog.Builder(context) .setTitle("Processing...") .setCancelable(true) .create(); final AsyncTask<MyParams, Object, MyResult> task = new AsyncTask<MyParams, Object, MyResult>() { @Override protected MyResult doInBackground(MyParams... params) { // Long operation goes here } @Override protected void onPostExecute(MyResult result) { dialog.dismiss(); onCompletion(result); } }; task.execute(...); dialog.setOnCancelListener(new OnCancelListener() { @Override public void onCancel(DialogInterface arg0) { task.cancel(false); } }); dialog.show(); From what I have read (http://bend-ing.blogspot.com/2008/11/properly-handle-progress-dialog-in.html) and seen in Android sources, it looks like the only possible situation to get that exception is when activity was destroyed. But as I have mentioned, I forbid activity recreation for basic events. So any suggestions are very appreciated.

  • Identical files from different servers. Why might IE 8 display them differently?

    - by jasongetsdown
    I'm working on a site that will go on my company's intranet. I developed it locally on my computer, checking it in different browsers and on colleague's computers, and when it was done I handed it off to IT. They put identical copies on a staging server, and on the production server. This is a site built only with html, javascript, and css. No server side scripting. It also uses a DWF viewer plugin from Autodesk. It is a single standalone page (not part of a CMS) that allows users to load drawings into the viewer and then click to see info from a database of space info saved in a series of js arrays (the space DB software spits out a js file with all the info listed in array literals, creating a crap ton of global variables - ugh, but I digress). When I followed their links (using IE 8) the version on the staging server looked as expected, but the layout is hosed on the version from the production server. Specifically, it seems like a div that is supposed to flow to the right of a div that is float: left is displaying below the floated div at full width, as though it was clear: left (which it is not). It also has the wrong height. I downloaded the files from each and they are identical to my local version. Frustrated, I cleared my browser's cache, restarted my computer, checked it on a colleague's computer who also has IE 8. All the same issue. Staging server good. Production server bad. Finally I uninstalled IE 8 and looked at it in IE 6. Both versions looked fine. So, to recap. Two different servers. No server side scripting. Identical files. One browser agrees they are identical, the other does not. What could cause this?

  • JQuery AJAX returned too much data that I had not requested

    - by kwokwai
    Hi all, I am using CakePHP 1.26 and CDN JQuery in this URL: http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js In a HTML web page, I have these lines of code: $.ajax({ type: "POST", url: "http://mywebsite.com/controllers/avail/"+curl, success: function(data) { alert(data);} }); and in the PHP page, I got another few lines of code: function avail($uname){ $result1=$this->Site1->User->findByusername($uname); if($result1){ return 1; } else{ return 0; } } As you see, the Avail function will return either zero or one. But there was some redundant data returned from the server, what I saw in the Alert box was somthing like this (rather than 0 or 1): <!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>Missing Method in Controller</title> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <style type="text/css"> /* CSS Document */ /*PAGE LAYOUT*/ 0

  • Dynamic editor upload into web page. Need advice

    - by Andrew Florko
    Hello everybody, I am writing intranet site for tracking employees science activities in organization. There lots of editable information on each personal page (science degree, publications & so on) so I upload editor per request (user clicks "edit" and modal dialog with html editor: set of textboxes/comboboxes/autocomplete features & validation logic appears). Editor is html layout that is wrapped with jquery dialog plugin + some logic, written as javascript functions that should be invoked from the callee page (onsubmit, validate, afterLoad editor events). There are also attributes (editor preferrable with and height) that are passed to callee page also. Currently I send these functions & attribute as ... function onsubmit() { }; function validate() { } var width = 640; var height = 800 ... code that is embedded into the request page. Function calls and editor markup wrap with jquery plugin completed in the callee page. It works, but I have some try { call editor event handler } catch { } stuff in callee page (because not every editor provides these functions) and some attributes (editor width & height for instance) that are loaded as variables declared in javascript. Please, suggest, is there a better approach to build & use custom editors for my situation. Thank you in advance!

  • Relatively simple task: How do I pass back the selected item from one activity to another?

    - by Brian D
    I have two activities: one displays an image and a button, the other displays a photo gallery. I want to be able to select any of the images in the gallery and then display them on the first activity in place of the default image. public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.gallery); Gallery g = (Gallery) findViewById(R.id.gallery); g.setAdapter(new ImageAdapter(this)); g.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView parent, View v, int position, long id) { Toast.makeText(PhotoGallery.this, "Position: " + id, Toast.LENGTH_SHORT).show(); Intent intent=new Intent(); intent.putExtra("PictureID", position); setResult(RESULT_OK, intent); finish(); } }); } Am I even close here? I'm not quite sure what to do with any string or int I would attach to the Intent -- can I attach the object itself? I'd much rather pass back at minimum the string name of the resource (image), but the only thing I can seem to figure out right now is how to pass back the position of the picture ... not a great solution. I can clarify more if necessary -- thanks.

  • Using an element against an entire list in Haskell

    - by Snick
    I have an assignment and am currently caught in one section of what I'm trying to do. Without going in to specific detail here is the basic layout: I'm given a data element, f, that holds four different types inside (each with their own purpose): data F = F Float Int, Int a function: func :: F -> F-> Q Which takes two data elements and (by simple calculations) returns a type that is now an updated version of one of the types in the first f. I now have an entire list of these elements and need to run the given function using one data element and return the type's value (not the data element). My first analysis was to use a foldl function: myfunc :: F -> [F] -> Q myfunc y [] = func y y -- func deals with the same data element calls myfunc y (x:xs) = foldl func y (x:xs) however I keep getting the same error: "Couldn't match expected type 'F' against inferred type 'Q'. In the first argument of 'foldl', namely 'myfunc' In the expression: foldl func y (x:xs) I apologise for such an abstract analysis on my problem but could anyone give me an idea as to what I should do? Should I even use a fold function or is there recursion I'm not thinking about?

Here is my code: int audioSource = AudioSource.MIC; int sampleRateInHz = 44100; int channelConfig = AudioFormat.CHANNEL_IN_MONO; int audioFormat = AudioFormat.ENCODING_PCM_16BIT; int bufferSizeInShorts = 44100; int bufferSizeInBytes = 2*bufferSizeInShorts; short Data[] = new short[bufferSizeInShorts]; Thread recordingThread; AudioRecord audioRecorder = new AudioRecord(audioSource, sampleRateInHz, channelConfig, audioFormat, bufferSizeInBytes); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } public void startRecording(View arg0) { audioRecorder.startRecording(); recordingThread = new Thread(new Runnable() { public void run() { while (Data[bufferSizeInShorts-1] == 0) audioRecorder.read(Data, 0, bufferSizeInShorts); } }); audioRecorder.stop(); } Unfortunately my short array is empty after the recording is over.

  • Prawn image position

    - by John
    I'm trying to layout 6 images per page with prawn in Ruby: case (idx % 6) # ugly when 0 : (pdf.start_new_page; pdf.image img, :position => :left, :vposition => :top, :width => 270) when 1 : pdf.image img, :position => :right, :vposition => :top, :width => 270 when 2 : pdf.image img, :position => :left, :vposition => :center, :width => 270 when 3 : pdf.image img, :position => :right, :vposition => :center, :width => 270 when 4 : pdf.image img, :position => :left, :vposition => :bottom, :width => 270 when 5 : pdf.image img, :position => :right, :vposition => :bottom, :width => 270 end Not sure what I'm doing wrong, but it prints the first 3 images to the PDF, then creates a new page and prints the last three: Page 1: <img> <img> <blank> <blank> <blank> <blank> Page 2: <blank> <blank> <blank> <img> <img> <img> Any suggestions would help.

  • Android ProgressDialog inside another dialog

    - by La bla bla
    I'm working on a game using AndEngine, and I need to show the users the list of his Facebook friends. I've created my custom Adatper and after the loading finishes everything works great. I have a problem with the loading it self. The ListView is inside a custom dialog, since I don't really know how to create one using AndEngine, So inside this dialog, I'm running an AsyncTask to fetch the friends' info, in that AsyncTask I'm have a ProgressDialog. The problem is, the ProgressDialog shows up behind the dialog that contains the to-be list (which while loading, is just the title). I can see the ProgressDialog "peeking" behind that dialog.. Any Ideas? Here's some code: FriendsDialog.java private ProgressDialog dialog; //Constructor of the AsyncTask public FriendsLoader(Context context) { dialog = new ProgressDialog(context); dialog.setMessage("Please wait..\nLoading Friends List."); } @Override protected void onPreExecute() { dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); dialog.setView(inflater.inflate(R.layout.loading, null)); dialog.setMessage("Please wait..\nLoading friends."); dialog.show(); } @Override protected void onPostExecute(ArrayList<HashMap<String, Object>> data) { if (dialog.isShowing()) { dialog.dismiss(); } MyAdapter myAdapter = new MyAdapter(context, data); listView = (ListView) findViewById(R.id.list); listView.setAdapter(myAdapter); listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) { String id = (String) listView.getItemAtPosition(myItemInt); listener.onUserSelected(id); dismiss(); } }); }

  • Need help with a custom Spinner/ArrayAdapter setup

    - by MisterSquonk
    I have a WeatherSpinner class which extends Spinner. The class shows region names which I originally did using an ArrayAdapter<String> but I now want to use ArrayAdapter<Locale>(Locale is an abstract 'empty' class of my own). I'm getting a ClassCastException when trying to populate my ArrayAdapter with the following... protected ArrayList<?> theList; protected ArrayAdapter<Locale> aa = null; ... protected void updateContents(ArrayList<?> list, int selectedItem) { theList = list; // Exception thrown on next line aa = new ArrayAdapter<Locale>(theContext, android.R.layout.simple_spinner_item, (Locale[]) theList.toArray()); ... } I'm passing a RegionList object into updateContents() as the 'list' parameter and RegionList extends ArrayList<Region>, and Region extends Locale. I've also overriden Region's toString() method to return a valid String. What am I not seeing here? Am I wrong about the way ArrayList<?>.toArray() works?

  • iOS6: do we have to set rootViewController in App delegate in order to support different orientations?

    - by Centurion
    The app was perfectly fine working in iOS5 in landscape orientation. However in iOS6, it started to use portrait orientation in all view controllers. The methods shouldAutorotateToInterfaceOrientation are not called anymore. I read the new stuff about changed rotation mechanism in iOS6 and I was able to fix that by adding a line in my AppDelegate: self.window.rootViewController = _viewController _viewControler is the starting screen (Home-menu). All other view controllers implement shouldAutorotateToInterfaceOrientation method and returns YES for landscape orientations only. So, it's perfectly working solution for the app that needs to support only one orientation. However, the problem is I need one view controller (lets call it phone-VC) to be presented in portrait orientation. Now, if I want this view controller would be rotated then I need to return YES in Home-menu controller that is assigned to rootViewControler in appDelegate. However, I can't do that because this rootViewController is starting window that need to presented in landscape only, otherwise the layout with graphics in this window will break. But if I don't return YES from its shouldAutorotateToInterfaceOrientation (Home-menu) then the same method is not called in my view phone-VC that needs to be presented in portrait. Any ideas? Does the assignation of rootViewController is mandatory in AppDelegate? UPDATE: the problem exists on device (at least on iPhone4).

  • UML diagrams that are actually pretty?

    - by Borek
    I'm looking for a diagramming software that would produce good looking output. It doesn't need to support everything (or even much) from UML, is doesn't need to have code engineering functions or anything, it just needs to produce visually interesting output. Here is a couple of samples of products that I consider ugly / not good enough: Visio with default UML stencils (didn't find better looking ones), Enterprise Architect, Dia, ArgoUML and many other "professional" UML tools. A couple of visually compelling tools that I considered (but found issues with): Visual Studio class diagrams - just for .NET classes but the output is miles better than what UML tools typically produce NClass - similar to VS's class diagrams but I could not find the "pretty", blue skin anywhere yuml.me - very nice but lacking some advanced layout options. I have to say that I find their style almost ideal for high-level diagrams - they look sketchy which is good. Balsamiq - I think Joel used this for hginit.com and I liked it. However, it's not suited for creating software diagrams so I can imagine it would be quite a lot of work MS Word has actually quite a good graphics engine but I'd rather leave this as a choice of the last resort I'd be grateful for any good tips.

  • iPhone app. Creating a custom UIView that contains UITextField and UIButton.

    - by Dmitry Burchik
    Hi all. I am new to iPhone programming. And I have an issue. I need to create a custom user control that I will add to my UIScrollView dinamically. The control has an UITextField and an UIButton. See the code below: #import <UIKit/UIKit.h> @interface FieldWithValueControl : UIView { UITextField *txtTagName; UIButton *addButton; } @property (nonatomic, readonly) UITextField *txtTagName; @property (nonatomic, readonly) UIButton *addButton; @end #import "FieldWithValueControl.h" #define ITEM_SPACING 10 #define ITEM_HEIGHT 20 #define SWITCHBOX_WIDTH 100 #define SCREEN_WIDTH 320 #define ITEM_FONT_SIZE 14 #define TEXTBOX_WIDTH 150 @implementation FieldWithValueControl @synthesize txtTagName; @synthesize addButton; - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code txtTagName = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, TEXTBOX_WIDTH, ITEM_HEIGHT)]; txtTagName.borderStyle = UITextBorderStyleRoundedRect; addButton = [UIButton buttonWithType:UIButtonTypeContactAdd]; [addButton setFrame:CGRectMake(ITEM_SPACING + TEXTBOX_WIDTH, 0, ITEM_HEIGHT, ITEM_HEIGHT)]; [addButton addTarget:self action:@selector(addButtonTouched:) forControlEvents:UIControlEventTouchUpInside]; [self addSubview:txtTagName]; [self addSubview:addButton]; } return self; } - (void)addButtonTouched:sender { UIButton *button = (UIButton*)sender; NSString *title = [button titleLabel].text; } - (void)drawRect:(CGRect)rect { // Drawing code } - (void)dealloc { [txtTagName release]; [addButton release]; [super dealloc]; } @end In my code I create an object of that class and add it to scrollView on form. FieldWithValueControl *newTagControl = (FieldWithValueControl*)[[FieldWithValueControl alloc] initWithFrame:CGRectMake(ITEM_SPACING, currentOffset + ITEM_SPACING, 0, 0)]; [scrollView addSubview:newTagControl]; The control looks fine, but if I click to the textbox or to the button nothing happens. Keyboard doesn't appear, the button is not clickable etc.

  • What, if any, printable character did a user type based on the values in a given System.Windows.Form

    - by Corey Trager
    As a workaround for a problem, I think I have to handle KeyDown events to get the printable character the user actually typed. KeyDown supplies me with a KeyEventArgs object with the properities KeyCode, KeyData, KeyValue, Modifiers, Alt, Shift, Control. My first attempt was just to consider the KeyCode to be the ascii code, but KeyCode on my keyboard is 46, a period ("."), so I end up printing a period when the user types the delete key. So, I know my logic is inadequate. (For those who are curious, the problem is that I have my own combobox in a DataGridView's control collection and somehow SOME characters I type don't produce the KeyPress and TextChanged ComboBox events. These letters include Q, $, %.... This code will reproduce the problem. Generate a Form App and replace the ctor with this code. Run it, and try typing the letter Q into the two comboxes. public partial class Form1 : Form { ComboBox cmbInGrid; ComboBox cmbNotInGrid; DataGridView grid; public Form1() { InitializeComponent(); grid = new DataGridView(); cmbInGrid = new ComboBox(); cmbNotInGrid = new ComboBox(); cmbInGrid.Items.Add("a"); cmbInGrid.Items.Add("b"); cmbNotInGrid.Items.Add("c"); cmbNotInGrid.Items.Add("d"); this.Controls.Add(cmbNotInGrid); this.Controls.Add(grid); grid.Location = new Point(0, 100); this.grid.Controls.Add(cmbInGrid); }

  • Quick questions re moving to InfoPath forms

    - by sweissman
    Hi there: I’ve been asked to look into how best to move forms into InfoPath and have a couple of basic questions about your experiences so I can get an insider’s lay of the land. Even some short, quick bullets would be really helpful -- thank you! Are you starting from scratch in InfoPath, or are you converting from paper or a different e-format? (Jetform, PDF, etc.) Are you trying to re-create the layout of a specific paper form, or is a regular online form OK? (trying to learn what the latest thinking is about this) Do you need only simple fill and submit capabilities, or do you need programming for calculations, validation, database lookup/entry/reporting, etc. as well? (don’t know how much harder it is to do all this vs. not) How long does each form take to finish? (I know it depends, but is there a rough guideline for planning purposes?) Who’s doing the actual work? (by title or function) What is especially straightforward or challenging about moving to InfoPath forms? (forewarned is forearmed!)

  • Getting an updated location in Android

    - by jul
    Hi, I'm using the code shown below to get an updated value for location every time a button is clicked. When my activity is resumed I get an update every second, so that when I call getLastKnownLocation I expect to have a location that have been updated in the last second. Is that the correct way to do that? I would expect the onLocationChanged event to be triggered every time I execute a 'geo fix' command (or max after 1s since I request update every 1s), but it's only triggered the first time. Why? Any help/suggestion welcome! Thanks package org.digitalfarm.atable; ... public class Atable extends Activity { private Button mSearchButton; private TextView mytext; private LocationManager locationManager; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mSearchButton = (Button)this.findViewById(R.id.button); mytext = (TextView) findViewById(R.id.dude); locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); final Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_FINE); mSearchButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { String provider = locationManager.getBestProvider(criteria, true); Location location = locationManager.getLastKnownLocation(provider); } }); } //Start a location listener LocationListener onLocationChange=new LocationListener() { public void onLocationChanged(Location loc) { //sets and displays the lat/long when a location is provided String latlong = "Lat: " + loc.getLatitude() + " Long: " + loc.getLongitude(); mytext.setText(latlong); } public void onProviderDisabled(String provider) { // required for interface, not used } public void onProviderEnabled(String provider) { // required for interface, not used } public void onStatusChanged(String provider, int status, Bundle extras) { // required for interface, not used } }; //pauses listener while app is inactive @Override public void onPause() { super.onPause(); locationManager.removeUpdates(onLocationChange); } //reactivates listener when app is resumed @Override public void onResume() { super.onResume(); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,100.0f,onLocationChange); } }

  • What is the best way to do scoped finds based on access control rules in Rails?

    - by Rafael Szuminski
    Hi I need to find an elegant solution to scoped finds based on access control rules. Essentially I have the following setup: Users Customers AccessControl - Defines which user has access to another users data Users need to be able to access not just their own customers but also shared customers of other users. Obviously something like a simple association will not work: has_many :customers and neither will this: has_many :customers, :conditions => 'user_id in (1,2,3,4,5)' because the association uses with_scope and the added condition is an AND condition not an OR condition. I also tried overriding the find and method_missing methods with the association extension like this: has_many :customers do def find(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end def method_missing(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end end but the issue is that I don't have access to the user object / parent object inside the extension methods and it just does not work as planned. I also tried default_scope but as posted here before you can't pass a block to a default scope. Anyhow, I know that data segmentation and data access controls have been done before using rails and am wondering if somebody found an elegant way to do it. UPDATE: The AccessControl table has the following layout user_id shared_user_id The customer table has this structure: id account_id user_id first_name last_name Assuming the the following data would be in the AccessControl table: 1 1 1 3 1 4 2 2 2 13 and so on... And the account_id for user 1 is 13 I need to be able to retrieve customers that can be best described with the following sql statement: select * from customers where (account_id = 13 and user_id = null) or (user_id in (1,3,4))

  • How to handle Win+Shift+LEft/Right on Win7 with custom WM_GETMINMAXINFO logic?

    - by Steven Robbins
    I have a custom windows implementation in a WPF app that hooks WM_GETMINMAXINFO as follows: private void MaximiseWithTaskbar(System.IntPtr hwnd, System.IntPtr lParam) { MINMAXINFO mmi = (MINMAXINFO)Marshal.PtrToStructure(lParam, typeof(MINMAXINFO)); System.IntPtr monitor = MonitorFromWindow(hwnd, MONITOR_DEFAULTTONEAREST); if (monitor != System.IntPtr.Zero) { MONITORINFO monitorInfo = new MONITORINFO(); GetMonitorInfo(monitor, monitorInfo); RECT rcWorkArea = monitorInfo.rcWork; RECT rcMonitorArea = monitorInfo.rcMonitor; mmi.ptMaxPosition.x = Math.Abs(rcWorkArea.left - rcMonitorArea.left); mmi.ptMaxPosition.y = Math.Abs(rcWorkArea.top - rcMonitorArea.top); mmi.ptMaxSize.x = Math.Abs(rcWorkArea.right - rcWorkArea.left); mmi.ptMaxSize.y = Math.Abs(rcWorkArea.bottom - rcWorkArea.top); mmi.ptMinTrackSize.x = Convert.ToInt16(this.MinWidth * (desktopDpiX / 96)); mmi.ptMinTrackSize.y = Convert.ToInt16(this.MinHeight * (desktopDpiY / 96)); } Marshal.StructureToPtr(mmi, lParam, true); } It all works a treat and it allows me to have a borderless window maximized without having it sit on to of the task bar, which is great, but it really doesn't like being moved between monitors with the new Win7 keyboard shortcuts. Whenever the app is moved with Win+Shift+Left/Right the WM_GETMINMAXINFO message is received, as I'd expect, but MonitorFromWindow(hwnd, MONITOR_DEFAULTTONEAREST) returns the monitor the application has just been moved FROM, rather than the monitor it is moving TO, so if the monitors are of differing resolutions the window end up the wrong size. I'm not sure if there's something else I can call, other then MonitorFromWindow, or whether there's a "moving monitors" message I can hook prior to WM_GETMINMAXINFO. I'm assuming there is a way to do it because "normal" windows work just fine.

  • Should developers *really* have private offices?

    - by Aron Rotteveel
    We will probably be moving within a year, so we have to make some decisions regarding office layout. At the moment, our company is basically one big office. When our developers can't bother to be disturbed at all, we all have our own headphones to mute the outside world. Still, it seems a lot of people feel that private offices are no doubt the way to go. From Joel's article Private Offices Redux: Not every programmer in the world wants to work in a private office. In fact quite a few would tell you unequivocally that they prefer the camaradarie and easy information sharing of an open space. Don't fall for it. They also want M&Ms for breakfast and a pony. Open space is fun but not productive. Even though I can understand the benefit on productivity, does having a private office really result in more net productivity? There seem to be plenty of companies that create wide open spaces and still maintain good productivity. Or so it seems. (I should mention many of them use cubicles, though) What is your opinion on this? What does your company do? Is there some middle ground in this? Some more related information on this matter: Private Offices Redux The new Fog Creek office A Field Guide to Developers Gmail recruitment page. Found this last one somewhat remarkable since the Gmail recruitment page promotes the "wide open space" idea.
