• C# WPF XAML Problem with icon in GridViewColumn

  - by Alex

  I've created a ListView with a GridView component in it. Now trying to fill one of the cells with an icon (PNG) like in the code sample below (save_icon.png): <ListView.View> <GridView> <GridViewColumn Header="Date" Width="Auto" DisplayMemberBinding="{Binding Date}" /> <GridViewColumn Header="Time" Width="Auto" DisplayMemberBinding="{Binding Time}" /> <GridViewColumn Header="FriendlyName" Width="Auto" DisplayMemberBinding="{Binding FriendlyName}" /> <GridViewColumn Width="Auto"> <Image Source="save_icon.png" /> </GridViewColumn> </GridView> </ListView.View> Visual Studio gives me an error on the line, where i put the icon into the column (ERROR: "Error 35: The file save_icon.png is not part of the project or its 'Build Action' property is not set to 'Resource'.") I added the icon to the project as a resource and when i start the app, everything works (the icon appears at the right place). But the WPF designer window can't be reloaded and i'm not able to see changes in the designer, when i change the XAML code. Can somebody explain this error or am i doing something wrong? Thanks for every hint in advance!

• WebView inside Tab hiding the tabWidgets

  - by brockoli

  I'm having trouble with a WebView always filling the full screen and thus covering my tabs. Here is my code for the tabhost.. public class tabNZBMobile extends TabActivity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Reusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, NewzbinMobile.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("search").setIndicator("Search", res.getDrawable(R.drawable.ic_tab_search)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, sabnzbWeb.class); spec = tabHost.newTabSpec("sabnzbweb").setIndicator("SabNZBd", res.getDrawable(R.drawable.ic_tab_sabnzbweb)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTabByTag("search"); }} My first tab (NewzbinMobile.class) displays correctly, it's just a relativelayout. But my second tab is an activity showing a webview and it is showing, but using the whole screen, covering my tabs. Here is the code for my second tab. public class sabnzbWeb extends Activity { WebView mWebView; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); String sabNZBurl = new String("http://test.server.org:8080/m"); mWebView = new WebView(this); mWebView.getSettings().setJavaScriptEnabled(true); setContentView(mWebView); mWebView.loadUrl(sabNZBurl); }}

• Automatically resize jQuery UI dialog to the width of the content loaded by ajax

  - by womp

  I'm having a lot of trouble finding specific information and examples on this. I've got a number of jQuery UI dialogs in my application attached to divs that are loaded with .ajax() calls. They all use the same setup call: $(".mydialog").dialog({ autoOpen: false, resizable: false, modal: true }); I just want to have the dialog resize to the width of the content that gets loaded. Right now, the width just stays at 300px (the default) and I get a horizontal scrollbar. As far as I can tell, "autoResize" is no longer an option for dialogs, and nothing happens when I specify it. I'm trying to not write a separate function for each dialog, so .dialog("option", "width", "500") is not really an option, as each dialog is going to have a different width. Specifying width: 'auto' for the dialog options just makes the dialogs take up 100% of the width of the browser window. What are my options? I'm using jQuery 1.4.1 with jQuery UI 1.8rc1. It seems like this should be something that is really easy. EDIT: I've implemented a kludgy workaround for this, but I'm still looking for a better solution.

• Aero Snap not working for my application

  - by Magnus Österlind

  I have a problem with Aero Snap not working with the application I'm working on (Windows desktop, native C++ application), and I'm a bit confused as to what's happening, as it seems like it should just work, out of the box. I've used Spy++ on a mininal win32 application, and get the following messages when I press Win-Left: <00070 00030D1C P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:0 fUp:0 <00071 00030D1C P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:1 fUp:0 <00072 00030D1C P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:1 fUp:0 <00088 00030D1C S WM_GETMINMAXINFO lpmmi:0043FCBC <00089 00030D1C R WM_GETMINMAXINFO lpmmi:0043FCBC <00090 00030D1C S WM_WINDOWPOSCHANGING lpwp:0043FCC4 <00091 00030D1C S WM_GETMINMAXINFO lpmmi:0043F8E8 <00092 00030D1C R WM_GETMINMAXINFO lpmmi:0043F8E8 <00093 00030D1C R WM_WINDOWPOSCHANGING .. and so on So I can see that the WM_KEYDOWN for the left key isn't reaching the application, but I'm getting the aero snap "resize window" stuff instead. When I Spy++ my application, I can see that the left key isn't being "intercepted", but instead being passed on to the application, so I don't get any snapping goodness. <00043 000F0F12 P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:0 fUp:0 <00044 000F0F12 P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:1 fUp:0 <00045 000F0F12 P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:1 fUp:0 <00060 000F0F12 P WM_KEYUP nVirtKey:VK_LEFT cRepeat:1 ScanCode:4B fRepeat:0 fUp:1 I'm going to dig into the cores of our message handling and see what's going on, but I'll take all the tips I can get :)

• WPF TextBlock Binding to DependencyProperty

  - by Bill Campbell

  Hi, I have what I believe to be about one of the most simple cases of attempting to bind a view to a dependencyproperty in the view model. It seems that the initial changes are reflected in the view but other changes to the DP do not update the view's TextBlock. I'm probably just missing something simple but I just can't see what it is. Please take a look... My XAML has a status bar on the bottom of the window. I want to bind to the DP "VRAStatus". <StatusBar x:Name="sbar" Grid.Column="0" Grid.Row="2" Grid.ColumnSpan="2" VerticalAlignment="Bottom" Background="LightBlue" Opacity="0.4" DockPanel.Dock="Bottom" > <StatusBarItem> <TextBlock x:Name="statusBar" Text="{Binding VRAStatus}" /> </StatusBarItem> <StatusBarItem> <Separator Style="{StaticResource StatusBarSeparatorStyle}"/> </StatusBarItem> </StatusBar> My viewmodel has the DP defined: public string VRAStatus { get { return (string)GetValue(VRAStatusProperty); } set { SetValue(VRAStatusProperty, value); } } // Using a DependencyProperty as the backing store for VRAStatus. public static readonly DependencyProperty VRAStatusProperty = DependencyProperty.Register("VRAStatus", typeof(string), typeof(PenskeRouteAssistViewModel),new PropertyMetadata(string.Empty)); Then, in my code I set the DP: VRAStatus = "Test Message..."; Is there something obvious here that I am missing? In my constructor for the viewmodel I set the DP like this: VRAStatus = "Ready"; I never get the Test Message to display. Please Help. thanks in advance! Bill

• Call Init from XUL after Page Loads (Firefox add-on)

  - by mattyboy123

  Hi all, I've been working on some code in js/html and it works great. I'm now trying to package it into an add-on for Firefox, and having some issues getting the XUL document correct. PLAIN OLD HTML/JS In my html test file between the <head></head> I have: <script type="text/javascript" src="js/MyCode.js"></script> At the end of the test file before the </body> I have: <script type="text/javascript">MyCode.Static.Init();</script> FIREFOX ADD-ON: OVERLAY.XUL In an overlay.xul file in the extension package I have : <?xml version="1.0"?> <overlay id="mycode" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script type="application/x-javascript" src="chrome://mycode/content/MyCode.js"></script> <script> window.addEventListener("load", function () { gBrowser.addEventListener("load",MyCode.Static.Init,true); }, false); </script> </overlay> This does not seem to enter the method, but then again I'm not even sure if I've got the listeners firing properly. Would this be the correct way to duplicate what I was doing in plain old html/js ?

• Trying to debug a 'Assertion failure in -[UIActionSheet showInView:]' error....

  - by dsobol

  I am working through "Beginning iPad Application Development" and am getting hung up in Chapter 3 where I have created a project that works with an Action Sheet. As it stands now, my application loads into the simulator just fine with no errors that I am aware of, but as it runs, it crashes with the following errors showing up in the debugger window: 2010-05-31 19:44:39.703 UsingViewsActionSheet[49538:207] * Assertion failure in -[UIActionSheet showInView:], /SourceCache/UIKit_Sim/UIKit-1145.66/UIAlert.m:7073 2010-05-31 19:44:39.705 UsingViewsActionSheet[49538:207] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: view != nil' I am sure that this is the block where the app breaks based upon my use of breakpoints. //Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { UIActionSheet *action = [[UIActionSheet alloc] initWithTitle:@"This is my Action Sheet!" delegate:self cancelButtonTitle:@"OK" destructiveButtonTitle:@"Delete Message!" otherButtonTitles:@"Option 1", @"Option 2", @"Option 3", nil]; [action showInView:self.view]; // <-- This line seems to trigger the crash.... [action release]; [super viewDidLoad]; } Am I missing something obvious, or is there more to the problem than is shown here? I have looked at the abstract for showInView and cannot divine anything there yet. I appreciate any and all asssitance. Regards, Steve O'Sullivan

• BitmapFrame in another thread

  - by Lasse Lindström

  Hi I am using a WPF BackgroundWorker to create thumbnails. My worker function looks like: private void work(object sender, DoWorkEventArgs e) { try { var paths = e.Argument as string[]; var boxList = new List(); foreach (string path in paths) { if (!string.IsNullOrEmpty(path)) { FileInfo info = new FileInfo(path); if (info.Exists && info.Length 0) { BitmapImage bi = new BitmapImage(); bi.BeginInit(); bi.DecodePixelWidth = 200; bi.CacheOption = BitmapCacheOption.OnLoad; bi.UriSource = new Uri(info.FullName); bi.EndInit(); var item = new BoxItem(); item.FilePath = path; MemoryStream ms = new MemoryStream(); PngBitmapEncoder encoder = new PngBitmapEncoder(); encoder.Frames.Add(BitmapFrame.Create(bi)); encoder.Save(ms); item.ThumbNail = ms.ToArray(); ms.Close(); boxList.Add(item); } } } e.Result = boxList; } catch (Exception ex) { //nerver comes here } } When this fuction is finnished and before the BackgroundWorker "Completed" function is started, I can see on the output window on Vs2008, that a exception is generated. It looks like: A first chance exception of type 'System.NotSupportedException' occurred in PresentationCore.dll The number of exceptions generates equals the number of thumbnails to be generated. Using "trial and error" I have isolated the problem to: BitmapFrame.Create(bi) Removing that line (makes my function useless) also removes the exception. I have not found any explanation to this,,, or a better method to create thumbnails i a background thread. Can anyone help me? //lasse

• After Navigate2 Method returns S_OK Stuck at READYSTATE of READYSTATE_LOADING

  - by Stone Free

  I am working on a MFC Document View architecture application which has multiple documents and views and a tabbed window interface. I have been tasked with making an automatic switch to another tab on the press of the OK button in one of the other tabs. When the other tab is clicked on it uses a C++ wrapper over IWebBrowser2 to navigate to a specific web page. When this is done manually by clicking on the tab everything is fine and the webpage within the view loads successfully. In my first attempt at doing this the tab successfully switched in response to a call to AfxGetMainWnd()->SendMessageToDescendants(SOME_MESSAGE, ...); however by sending this windows message at the wrong point the application would crash once control returned because the chain of events caused the (modeless) dialog (*) that sent the message, to no longer exist. I then found the correct place to make the call, but now when the other tab is activated, it no longer displays the webpage as it should. To debug this problem I added code to check the READYSTATE in both the situation where it works and the situation where it does not. When the page fails to load (despite the call to Navigate2 returning S_OK), the READYSTATE just stays at READYSTATE_LOADING. Unfortunately now I am to many edits away from when I had it partially working. I have added TRACE statements to the most obvious events such as OnSetFocus, CView::OnActivateView but all traces come out in the same order despite the behaviour being different * hosted in the view

• Getting Google results in Java? Need help!

  - by Cris Carter

  Hello. Right now, I'm trying to get the results from Google in Java, by searching for a term. I'm using a desktop program, not an applet. That in itself isn't complicated. but then Google gave me a 403 error. Anyways, I added referrer and User Agent and then it worked. Now, my problem is that I don't get the results page from Google. Instead, I get their script which gets the results page. My code right now simply uses a GET request on "http://www.google.com/search?q=" + Dork; Then it outputs each line. Here is what I get when I run my program: <.!doctype html<.head<.titledork - Google Search<./title<.scriptwindow.google={kEI:"9myaS-Date).getTime()}}};try{}catch(u){}window.google.jsrt_kill=1; align:center}#logo{display:block;overflow:hidden;position:relative;width:103px;height:37px; <./ script<./div Lots of stuff like that. I shortened it (A LOT) and put in dots to fit it here. So my big question is: How do I turn this whole mess into the nice results page I get when searching Google with a browser? Any help would be seriously appreciated, and I really need the answer fast. Also, please keep in mind that I do NOT want to use Google's API for this. Thanks in advance!

• IIS6 configuration for WCF/Silverlight

  - by Grayson Mitchell

  I am trying the simple senario of running a WCF service to return Active directory information on a user. (http://rouslan.com/2009/03/20-steps-to-get-together-windows-authentication-silverlight-and-wcf-service/) using Silverlight 4 & .net 4 However, I am being driven insane by trying to set this up in IIS. Currently I have my solution working in VS, but when I try to run the service in ISS a debug window tries to open... (and I can't get rid of it, is is complaining about the WCF call). <basicHttpBinding> <binding name="winAuthBasicHttpBinding"> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Ntlm"/> </security> </binding> </basicHttpBinding> The Insanity: I have got the IIS to successfully call a WCF service (but can't reproduce), I have created 5 projects to try and get this working, but in my 5th I can't even browse the site (says it can't download silverlight application, but mime type are setup). My next step is to install Server2008 on a test machine and try IIS7... as all the various walkthrough's I have found just dont seem to work in IIS6.

• Where's the Win32 resource for the mouse cursor for dragging splitters?

  - by Luther Baker

  I am building a custom win32 control/widget and would like to change the cursor to a horizontal "splitter" symbol when hovering over a particular vertical line in the control. IE: I want to drag this vertical line (splitter bar) left and right (WEST and EAST). Of the the system cursors (OCR_*), the only cursor that makes sense is the OCR_SIZEWE. Unfortunately, that is the big, awkward cursor the system uses when resizing a window. Instead, I am looking for the cursor that is about 20 pixels tall and around 3 or 4 pixel wide with two small arrows pointing left and right. I can easily draw this and include it as a resource in my application but the cursor itself is so prevalent that I wanted to be sure it wasn't missing something. For example: when you use the COM drag and drop mechanism (CLSID_DragDropHelper, IDropTarget, etc) you implicitly have access to the "drag" icon (little box under the pointer). I didn't see an explicit OCR_* constant for this guy ... so likewise, if I can't find this splitter cursor outright, I am wondering if it is part of a COM object or something else in the win32 lib.

• Dynamic Google Maps API InfoWindow HTML Content

  - by Peter Hanneman

  I am working in Flash Builder 4 with Google Map's ActionScript API. I have created a map, loaded some custom markers onto it and added some MouseEvent listeners to each marker. The trouble comes when I load an InfoWindow panel. I want to dynamically set the htmlContent based off of information stored in a database. The trouble is that this information can change every couple of seconds and each marker has a unique data set so I can not statically set it at the time I actually create the markers. I have a method that will every minute or so load all of the records from my database into an Object variable. Everything I need to display in the htmlContent is contained in this object under a unique identifier. The basic crux of the problem is that there is no way for me to uniquely identify an info window, so I can not determine what information to pull into the panel. marker.addEventListener(MapMouseEvent.ROLL_OVER, function(e:MapMouseEvent):void { showInfoWindow(e.latLng) }, false, 0, false); That is my mouse event listener. The function I call, "showInfowindow" looks like this: private function showInfoWindow(latlng:LatLng):void { var options:InfoWindowOptions = new InfoWindowOptions({title: appData[*I NEED A UNIQUE ID HERE!!!*].type + " Summary", contentHTML: appData[*I NEED A UNIQUE ID HERE!!!*].info}); this.map.openInfoWindow(latlng, options); } I thought I was onto something by being able to pass a variable in my event listener declaration, but it simply hates having a dynamic variable passed through, it only returns the last value use. Example: marker.addEventListener(MapMouseEvent.ROLL_OVER, function(e:MapMouseEvent):void { showInfoWindow(e.latLng, record.unit_id) }, false, 0, false); That solution is painfully close to working. I iterate through a loop to create my markers when I try the above solution and roll over a marker I get information, but every marker's information reflects whatever information the last marker created had. I apologize for the long explaination but I just wanted to make my question as clear as possible. Does anyone have any ideas about how to patch up my almost-there-solution that I posted at the bottom or any from the ground up solutions? Thanks in advance, Peter Hanneman

• DOS batch file to enter commands in proprietary java app and receive feedback?

  - by Justine

  Hello, I'm working on a project in which I'd like to be able to turn lights on and off in the Duke Smart Home via a high frequency chirp. The lighting system is called Clipsal Square-D and the program that gives a user access to the lighting controls is called CGate. I was planning on doing some signal processing in Matlab, then create a batch file from Matlab to interact with Cgate. Cgate is a proprietary Java app that, if run from a DOS command line, opens up another window that looks like the command prompt. I have a batch file that can check to see if Cgate is running and if not, open it. But what I can't figure out how to do is actually run commands in the Cgate program from the batch file and likewise, take the response from Cgate. An example of such a command is "noop," which should return "200 OK." Any help would be much appreciated! Thank you very much in advance :) (here's my existing batch file by the way) @ECHO off goto checkIfOpen :checkIfOpen REM pv finds all open processes and puts it in result.txt %SystemRoot%\pv\pv.exe %SystemRoot%\pv\pv.exe result.txt REM if result has the word notepad in it then notepad is running REM if not then it opens notepad FIND "notepad.exe" result.txt IF ERRORLEVEL 1 START %SystemRoot%\system32\Clipsal\C-Gate2\cgate.exe goto end :end

• How to get top and left style property values in Javascript

  - by Dude-Dastic

  Hi all, I have a little bit of Javascript that almost works correctly. Here's the code: function toggle(curlink) { curlink.style.backgroundColor = curlink.style.backgroundColor == "yellow" ? "transparent" : "yellow"; var maindiv = document.getElementById("grid"); var links = maindiv.getElementsByTagName("a"); var list = ""; for (var i = 0; i < links.length; ++i) { var link = links[i]; if (link.style.backgroundColor == "yellow") { list += ("," + parseInt(link.style.left, 10) + "-" + parseInt(link.style.top, 10)); } } document.theForm.theList.value = list.substring(1); return false; }; window.onload = function() { var links = document.getElementById("grid").getElementsByTagName("a"); for (var i = 0; i < links.length; ++i) { links[i].onclick = function() { return toggle(this); } } }; The issue is with line #9; it only works when I specify values for the top and left style property of every link in the array. How do I get the top and left style property values (or X and Y coordinates) of each link in the array with Javascript when those values aren't given? Also, what would the code above look like in jquery? Not that it's needed - I just want to reduce the code a little and dabble in the jquery framework (I'm a Javascript newbie). Thanks in advance, Dude-Dastic

• How to invalidate layout of listbox from custom children

  - by Stephen Price

  I have a custom panel for a listbox <ItemsPanelTemplate x:Key="FloatPanelTemplate"> <Controls:FloatPanel x:Name="CardPanel" /> </ItemsPanelTemplate> The panel lays out its children using its X and Y dependency properties. This all works nicely when the FloatPanel is used by itself - I'm using FrameworkPropertyMetadataOptions.AffectsArrange | FrameworkPropertyMetadataOptions.AffectsMeasure on the dependency properties of the child items to tell the FloatPanel to redraw its layout. When I use it in a Listbox (code above) then it draws fine the first time, but when I drag the children (which modifies the item's X and Y) it is not notifying the Listbox that it needs to redraw the FloatPanel's children. I think the issue is related to the fact that each item in the bound collection is wrapped with a ListBoxItem. Hopefully I've described what i'm doing well enough that someone can tell me how to make the panel (or its children) tell it needs to do the Layout routines again. As I said it works once (initial draw) but then dragging items doesn't work (Listbox isnt aware that its children have changed and needs to relayout.) If I drag an item and then resize the window, the listbox does a layout and the items are drawn in their new locations. How do I notify the ListBox (or more importantly the FloatPanel in the ItemsPanelTemplate) that it needs to do a Layout pass?

• Visual C++ Assembly link library troubles

  - by Sanarothe

  Hi. I'm having a problem having my projects built in VC++ Express 2008... I'm using a library, irvine32.inc/lib. INCLUDE Irvine32.inc works for me at school (On already configured VS environments) by default, but at home (Windows 7 x64) I'm having a boatload of issues. My original post here was that a file that irvine32.inc referenced, in the same folder, 'could not be opened.' Added irvine folder to the include path for specific project, progress. Then I was getting an error with mt.exe, but a suggestion on the MSDN suggested turn off antivirus, and now project does build but when I run a program that does NOT reference anything in irvine32, it tells me repeatedly that my project has triggered a breakpoint, and allows me to continue or break. Continue just pops the same window, break loads another popup telling me that "No symbols are loaded for any call stack frame. Source code cannot be displayed." This popup lets me view the disassembly. I tested it with and without working statements, it just throws the same breakpoint on the first line of code. Now, if I run the program when it DOES require something from the include file, in this case, DumpRegs: INCLUDE Irvine32.inc .data .code main PROC mov ebx,1000h mov eax,1000h add eax,ebx call DumpRegs main ENDP END main This gives me 1main.obj : error LNK2019: unresolved external symbol _DumpRegs@0 referenced in function _main@0 1C:\Users\Cameron\csis165\Lab8_CCarroll\Debug\Lab8_CCarroll.exe : fatal error LNK1120: 1 unresolved externals This does NOT happen when I build a project from the book author's examples, which has the same include statement. I'm baffled. :(

• Get the value for a WPF binding

  - by Jose

  Ok, I didn't want a bunch of ICommands in my MVVM ViewModels so I decided to create a MarkupExtension for WPF that you feed it a string(the name of the method), and it gives you back an ICommand that executes the method. here's a snippet: public class MethodCall : MarkupExtension { public MethodCall(string methodName) { MethodName = methodName; CanExecute = "Can" + methodName; } public override object ProvideValue(IServiceProvider serviceProvider) { Binding bin= new Binding { Converter = new MethodConverter(MethodName,CanExecute) }; return bin.ProvideValue(serviceProvider); } } public class MethodConverter : IValueConverter { string MethodName; public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { //Convert to ICommand ICommand cmd = ConvertToICommand(); if (cmd == null) Debug.WriteLine(string.Format("Could not bind to method 'MyMethod' on object",MethodName)); return cmd; } } It works great, except when the binding fails(e.g. you mistype). When you do this in xaml: {Binding MyPropertyName} you see in the output window whenever the binding fails. and it tells you the propertyName the Type name etc. The MethodConverter Class can tell you the name of the method that failed, but it can't tell you the source object type. Because the value will be null. I can't figure out how to store the source object type so for the following class public class MyClass { public void MyMethod() { } } and the following xaml: <Button Command={d:MethodCall MyMethod}>My Method</Button> It currently says: "Could not bind to method 'MyMethod' on object but I would like it to say: "Could not bind to method 'MyMethod' on object MyClass Any ideas?

• Why does VBA Find loop fail when called from Evaluate?

  - by Abiel

  I am having some problems running a find loop inside of a subroutine when the routine is called using the Application.Evaluate or ActiveSheet.Evaluate method. For example, in the code below, I define a subroutine FindSub() which searches the sheet for a string "xxx". The routine CallSub() calls the FindSub() routine using both a standard Call statement and Evaluate. When I run Call FindSub, everything will work as expected: each matching address gets printed out to the immediate window and we get a final message "Finished up" when the code is done. However, when I do Application.Evaluate "FindSub()", only the address of the first match gets printed out, and we never reach the "Finished up" message. In other words, an error is encountered after the Cells.FindNext line as the loop tries to evaluate whether it should continue, and program execution stops without any runtime error being printed. I would expect both Call FindSub and Application.Evaluate "FindSub()" to yield the same results in this case. Can someone explain why they do not, and if possible, a way to fix this? Thanks. Note: In this example I obviously do not need to use Evaluate. This version is simplified to just focus on the particular problem I am having in a more complex situation. Sub CallSub() Call FindSub Application.Evaluate "FindSub()" End Sub Sub FindSub() Dim rngFoundCell As Range Dim rngFirstCell As Range Set rngFoundCell = Cells.Find(What:="xxx", after:=ActiveCell, LookIn:=xlValues, _ LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _ MatchCase:=False, SearchFormat:=False) If Not rngFoundCell Is Nothing Then Set rngFirstCell = rngFoundCell Do Debug.Print rngFoundCell.Address Set rngFoundCell = Cells.FindNext(after:=rngFoundCell) Loop Until (rngFoundCell Is Nothing) Or (rngFoundCell.Address = rngFirstCell.Address) End If Debug.Print "Finished up" End Sub

• Android Custom Dialog NullPointerException

  - by Kyle Hughes

  I cannot for the life of me figure out why I'm getting a NullPointerException. When a user clicks on a particular image, a dialog window is supposed to pop-up and display a larger version of said image: private OnClickListener coverListener = new OnClickListener() { public void onClick(View v) { showDialog(DIALOG_COVER); } }; DIALOG_COVER is set to = 0. The associated onCreateDialog looks like this: protected Dialog onCreateDialog(int id) { Dialog dialog; switch(id) { case DIALOG_COVER: dialog = new Dialog(mContext); dialog.setContentView(R.layout.cover_dialog); dialog.setTitle(book.getTitle()); ImageView coverLarge = (ImageView)findViewById(R.id.coverLarge); coverLarge.setImageBitmap(book.getCover()); break; default: dialog = null; } return dialog; } For reference, this is cover_dialog.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/coverDialog" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp"> <ImageView android:id="@+id/coverLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="fitStart" /></LinearLayout> Now, when the image previously described is clicked, the application immediately crashes and throws the following error through LogCat: 06-08 13:29:17.727: ERROR/AndroidRuntime(2220): Uncaught handler: thread main exiting due to uncaught exception 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): java.lang.NullPointerException 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): at org.kylehughes.android.brarian.AndroidBrarian.onCreateDialog(AndroidBrarian.java:259) The line in question refers to this line inside of onCreateDialog: coverLarge.setImageBitmap(book.getCover()); Basically, I don't get why coverLarge is null at that point. Any help would be much appreciated.

• Get a JQuery function to execute after and independently of onLoad

  - by lewicki

  Is is possible to execute a JQuery function by injecting it into the page? IT CAN'T be attached to the .ready function. The reason is that the user will be uploading an image via iframe. I need JCrop to execute after I display the uploaded image. echo "<script>$('#pictures_step1_right_bottom1', window.parent.document).html('<img id=\"cropbox\" src=\"../../box/" . 'THM' . $filenameAlt . '.jpg' . "\">');</script>"; echo "<script>jQuery(function(){jQuery('#cropbox').Jcrop();});</script>"; This is executed in the iframe that is processing the image. it then sends it to the main page. This does not work however. EDIT: Ended up running a timer: function checkPic() { if($('#cropbox1').length != 0) { jQuery(function() { jQuery('#cropbox1').Jcrop(); }); } timer(); // Check size again after 1 second } function timer(){ var myTimer = setTimeout('checkPic()', 3000); // Check size every 1 second}

• VS2010 asking to upgrade SIlverlight??

  - by Lu10ntDan

  I'm running the absolute latest versions of Silverlight and Visual Studio 2010 Professional and built a solution that contained a WPF project. From there, I added a SketchFlow project (based on Blend 4 RC) and I can run each project within the solution just fine by setting whenever I switch between them as startup projects. From there, I added a Silverlight 4 Business Application (taking all the defaults), and when simply trying to set that as the startup project and running it, VS2010 is giving me the following error after trying to open a web page: Line: 56 (in file TestPage.aspx) Error: Unhandled Error in Silverlight Application Code: 8001 Category: InitializeError Message: Upgrade required If I choose not to debug, I get the Silverlight page saying "This page requires a more recent version of Silverlight"! Clicking "Install Now" on the popup window brings me to Mirosoft's Silverlight page where I see: "The version of Silverlight originally requested is not available. You can get a supported version from this page. This Web browser or operating system may not be compatible with Silverlight. Please review the system requirements and, if you wish to proceed, choose the link for your operating system." If I choose to upgrade anyway, I'm told that I'm running the latest version of Silverlight available. What the heck? I'm running the final versions of VS2010 Pro, Silverlight 4, and the latest version of Expression Blend 4 (RC). Why can't VS2010 run this default Silverlight Business App? Any ideas? Please?? Thanks, Lu10ntDn PS. This is on Windows 7 with UAC turned off, and ALL latest Windows Updates installed.

• Dynamically created iframe used to download file triggers onload with firebug but not without

  - by justkt

  EDIT: as this problem is now "solved" to the point of working, I am looking to have the information on why. For the fix, see my comment below. I have an web application which repeatedly downloads wav files dynamically (after a timeout or as instructed by the user) into an iframe in order to trigger the a default audio player to play them. The application targets only FF 2 or 3. In order to determine when the file is downloaded completely, I am hoping to use the window.onload handler for the iframe. Based on this stackoverflow.com answer I am creating a new iframe each time. As long as firebug is enabled on the browser using the application, everything works great. Without firebug, the onload never fires. The version of firebug is 1.3.1, while I've tested Firefox 2.0.0.19 and 3.0.7. Any ideas how I can get the onload from the iframe to reliably trigger when the wav file has downloaded? Or is there another way to signal the completion of the download? Here's the pertinent code: HTML (hidden's only attribute is display:none;): <div id="audioContainer" class="hidden"> </div> JavaScript (could also use jQuery, but innerHTML is faster than html() from what I've read): waitingForFile = true; // (declared at the beginning of closure) $("#loading").removeClass("hidden"); var content = "<iframe id='audioPlayer' name='audioPlayer' src='" + /path/to/file.wav + "' onload='notifyLoaded()'></iframe>"; document.getElementById("audioContainer").innerHTML = content; And the content of notifyLoaded: function notifyLoaded() { waitingForFile = false; // (declared at beginning of the closure) $("#loading").addClass("hidden"); } I have also tried creating the iframe via document.createElement, but I found the same behavior. The onload triggered each time with firebug enabled and never without it. EDIT: Fixed the information on how the iframe is being declared and added the callback function code. No, no console.log calls here.
