• Android: Autoscrolling HorizontalScrollView

  - by DroidIn.net

  I'm using the following code to simulate tabs and since there are more tabs that width can accommodate user can scroll left or right to make a tab button visible. It all works, however I also provide user with ability to fling between tabs by swiping finger left or right on the tab contents. Again - it works. But when I fling to the rightmost tab its corresponding button is barely visible. I want to autoscroll table inside the HorizontalScrollView so the selected tab button will be visible but when I execute HorizontalScrollView.smoothScrollTo(300, 0) nothing happens. It doen't matter how high I set first x parameter nothing will ever move (yes I do have an algorithm to calculate exact position). Here's XML code for scrolling tab buttons <HorizontalScrollView android:layout_width="fill_parent" android:background="@color/tabs_header" android:layout_height="55dip" android:scrollbars="none" android:id="@+id/tabsButtonView"> <TableLayout android:id="@+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TableRow android:id="@+id/TableRow01" android:layout_width="fill_parent" android:layout_weight="1" android:layout_height="0dip" android:paddingTop="5dip" android:paddingLeft="3dip"> <ImageButton android:src="@drawable/linkup_logo_small" android:id="@+id/tabBtt0" android:layout_width="wrap_content" android:layout_marginLeft="2dip" android:layout_marginRight="2dip" android:layout_height="fill_parent" android:padding="5dip" android:background="@drawable/tab_selected"></ImageButton> <ImageButton android:src="@drawable/simplyhired_small" android:id="@+id/tabBtt1" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_marginLeft="2dip" android:layout_marginRight="2dip" android:padding="5dip" android:background="@drawable/tab_normal"></ImageButton> <ImageButton android:src="@drawable/indeedcom_small" android:id="@+id/tabBtt2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dip" android:layout_marginLeft="2dip" android:layout_marginRight="2dip" android:background="@drawable/tab_normal"></ImageButton> <ImageButton android:src="@drawable/careerbuilder_logo_small" android:id="@+id/tabBtt3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dip" android:layout_marginLeft="2dip" android:layout_marginRight="2dip" android:background="@drawable/tab_normal"></ImageButton> </TableRow> </TableLayout> </HorizontalScrollView>

• ListView setOnItemClickListener and setOnItemSelectedListener to store the Selected Item Index

  - by Christophe

  Hi all, I have read on this site that it is necessary to customize the setOnItemSelectedListener and setOnItemClickListener of a ListView if we want to know the Index of the SelectedItem (.getSelectedItemPosition()). So that is what I do but it does not stores the position of the SekectedItem, instead i have always -1... What I want to do is just to give the user a way to delete items from a list by selected and Item and Clicking a button. See the code below : listViewPeople.setOnItemClickListener(new ListView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> a, View v, int i, long l) { try { // Remembers the selected Index listViewPeopleId = listViewPeople.getSelectedItemPosition(); } catch(Exception e) { System.out.println("Nay, cannot get the selected index"); } } }); listViewPeople.setOnItemSelectedListener(new ListView.OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> a, View v, int i, long l) { try { // Remembers the selected Index listViewPeopleId = listViewPeople.getSelectedItemPosition(); System.out.println("Yay, set the selected index " + listViewPeopleId); } catch(Exception e) { System.out.println("Nay, cannot get the selected index " + listViewPeopleId); } } @Override public void onNothingSelected(AdapterView<?> arg0) { try { // Remembers nothing selected listViewPeopleId = -1; System.out.println("Yay, set that nothing is selected " + listViewPeopleId); } catch(Exception e) { System.out.println("Nay, cannot set that nothing is selected " + listViewPeopleId); } } }); What's wrong?? Thank you for your help! Christophe

• CSS overflow: hidden; does not work

  - by kapil.israni

  Hi - I am having issues with overflow: hidden not working in my case. I have a div id=ticker which basically works like a scrolling ticker. something like this - http://www.tinymassive.com/ (whats happening section). So i am prepending dynamic content to div id=ticker The div id=ticker is contained in another div which is contained in another div, basically think of it like 4-5 level tree like structure body - div[id=wrapper] - div[class=main] - div[class=content] - div[class=frame] - div[class=bg] - div[class=primary-content] - div[id=ticker] Heres the css... #wrapper { width: 942px; margin: 0 auto; position:relative; overflow:hidden; } .main{ width:942px; margin:163px 0 0; overflow:hidden; } .content{ background:url(../images/content-bg.gif) repeat-y; overflow:hidden; width:662px; float:left; } .frame{ background:url(../images/frame-bg.gif) no-repeat 0 0; width:662px; } .bg{ background:url(../images/bg-bg.gif) no-repeat 0 100%; width:662px; overflow:hidden; } .primary-content{ padding: 12px 20px 40px 22px; width:620px; overflow:hidden; } #ticker { overflow: hidden; } Also if it helps - the ticker div contains a list of div[class=breadcrumps], which i am trying to scroll .breadcrumbs{ border-bottom:1px solid #ebebeb; padding:6px 0 6px 0; overflow:hidden; clear:both; } What i see is - when i prepend breadcrumps div to ticker, the page/ticker list keeps getting bigger :( Any help would be appreciated. Thanks.

• Correctly calling setGridWidth on a jqGrid inside a jQueryUI Dialog

  - by Dan

  I have a jQueryUI dialog (#locDialog) which has a jqGrid ($grid) inside it. When the Dialog opens (initially, but it gets called whenever it opens), I want the $grid to resize to the size of the $locDialog. When I do this initially, I get scrollbars inside the grid (not inside the dialog). If I debug the code, I see the width of the $grid is 677. So, I call setGridWidth() again and check the width and now I have 659, which is 18px less, which is the size of the scroll area for the jqGrid (Dun-dun-dun..) When I rezie the dialog, I resize the grid as well, and everything is happy - no scrollbars, except where necessary. My dialog init code: $locDialog = $('#location-dialog').dialog({ autoOpen: false, modal: true, position: ['center', 100], width: 700, height:500, resizable: true, buttons: { "Show Selected": function() {alert($('#grid').jqGrid('getGridParam','selarrrow'));}, "OK": function() {$(this).dialog('close');}, "Cancel": function() {$(this).dialog('close');} }, open: function(event, ui) { $grid.setGridHeight($(this).height()-54); // No idea why 54 is the magic number here $grid.setGridWidth($(this).width(), true); }, close: function(event, ui) { }, resizeStop: function(event, ui) { $grid.setGridWidth($locDialog.width(), true); $grid.setGridHeight($locDialog.height()-54); } }); I am curious if anyone has seen this before. Really, it isn't the end of the world if I initially have unnecessary scrollbars at first, but it is just odd that when I call setGridWidth initially, it doesn't take into account the scroll area of 18px. As far as the magical number 54, that is the number I had to subtract from the height of the dialog value to get the grid to render without unnecessary scrollbars.

• Mimicking the UltraGridColumnChooser's drag & drop ability

  - by Sören Kuklau

  (Infragistics 2008 Vol. 3, CLR 2.0) Infragistics's UltraGrid comes with a column chooser user control, which is simply a vertical arrangement of columns with checkboxes that toggle a column's hidden state. In addition, it allows you to pick a column and drag it directly to the grid so you don't have to manually position it afterwards. (This is particularly handy when you already have a lot of visible columns and have no clue where the new one ended up.) I'm building my own column chooser based on an UltraTree. Getting the checkboxes to behave the same wasn't an issue, but I haven't found a way to drag a column from the tree to the grid and have it accept it. In my tree, each UltraTreeNode has a Tag with the following struct: Private Structure DraggableGridColumn Public NodeKey As String Public NodeName As String Public ParentKey As String Public Column As UltraGridColumn End Structure I then have an event as follows: Private Sub columnsTree_SelectionDragStart(ByVal sender As Object, ByVal e As System.EventArgs) Handles columnsTree.SelectionDragStart If columnsTree.SelectedNodes.Count <> 1 Then Return End If If Not TypeOf columnsTree.SelectedNodes(0).Tag Is DraggableGridColumn Then Return End If Dim column As UltraGridColumn = CType(columnsTree.SelectedNodes(0).Tag, DraggableGridColumn).Column columnsTree.DoDragDrop(column, DragDropEffects.All) End Sub In the DoDragDrop call, neither column (of type UltraGridColumn) nor column.Header (of type ColumnHeader) get accepted by the grid. I assume I'm sending the wrong type, and/or that the grid expects a special struct with some additional information. Unfortunately, I've also failed to catch an event (both on the column chooser side as well as on the grid side) where Infragistics's normal column chooser does this properly; the normal drag & drop events never seem to fire.

• WCF - The maximum nametable character count quota (16384) has been exceeded while reading XML data.

  - by Jankhana

  I'm having a WCF Service that uses wsHttpBinding. The server configuration is as follows : <bindings> <wsHttpBinding> <binding name="wsHttpBinding" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> <security mode="None"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> At the client side I'm including the Service reference of the WCF-Service. It works great if I have limited functions say 90 Operation Contract in my IService but if add one more OperationContract than I'm unable to Update the Service reference nor i'm able to add that service reference. In this article it's mentioned that by changing those config files(i.e devenv.exe.config, WcfTestClient.exe.config and SvcUtil.exe.config) it will work but even including those bindings in those config files still that error pops up saying There was an error downloading 'http://10.0.3.112/MyService/Service1.svc/mex'. The request failed with HTTP status 400: Bad Request. Metadata contains a reference that cannot be resolved: 'http://10.0.3.112/MyService/Service1.svc/mex'. There is an error in XML document (1, 89549). The maximum nametable character count quota (16384) has been exceeded while reading XML data. The nametable is a data structure used to store strings encountered during XML processing - long XML documents with non-repeating element names, attribute names and attribute values may trigger this quota. This quota may be increased by changing the MaxNameTableCharCount property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 1, position 89549. If the service is defined in the current solution, try building the solution and adding the service reference again. Any idea how to solve this????

• jqGrid Export to CSV Missing Column Names

  - by user561557

  I have a jqGrid that works perfectly. It contains a pager button to export the grid to a csv file which works and exports the data. However, I also need to have the column names exported with the data and I can't seem to get that to work. My working code follows. jQuery("#detail").jqGrid('navGrid','#pager2', {height:520,width:500,savekey:[true,13],navkeys:[true,38,40],reloadAfterSubmit:false, jqModal:false, closeOnEscape:true, bottominfo:"Fields marked with () are required"}, // edit options {height:520, width:500,savekey:[true,13],reloadAfterSubmit:false,jqModal:false, closeOnEscape:true,bottominfo:"Fields marked with () are required", closeAfterAdd: true}, // add options {reloadAfterSubmit:false,jqModal:false, closeOnEscape:true}, // del options {closeOnEscape:true}, // search options {height:250,width:500,jqModal:false,closeOnEscape:true}, {view:true} // view options ); // add custom button to export the data to excel jQuery("#detail").jqGrid('navButtonAdd','#pager2',{ caption:"", title:"Export to CSV", onClickButton : function () { exportExcel(); }, position:"last" }); // add custom button to print grid jQuery("#detail").jqGrid('navButtonAdd','#pager2',{ caption:"", title:"Print", buttonicon:"ui-icon-print", onClickButton : function () { jQuery('#detail_table').jqprint({ operaSupport: true }); return false; } }); function exportExcel() { var mya=new Array(); mya=jQuery("#detail").getDataIDs(); // Get All IDs var data=jQuery("#detail").getRowData(mya[0]); // Get First row to get the labels var colNames=new Array(); var ii=0; for (var i in data){colNames[ii++]=i;} // capture col names var html=""; for(i=0;i } html=html+"\\n"; // end of line at the end document.forms[0].method='POST'; document.forms[0].action='ajax/csvExport.php'; // send it to server which will open this contents in excel file document.forms[0].target='_blank'; document.forms[0].csvBuffer.value=html; document.forms[0].submit(); }

• How to extract $lastexitcode from c# powershell script execution.

  - by scope-creep

  Hi, I've got a scipt executing in C# using the powershell async execution code on code project here: http://www.codeproject.com/KB/threads/AsyncPowerShell.aspx?display=PrintAll&fid=407636&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=2130851#xx2130851xx I need to return the $lastexitcode and Jean-Paul describes how you can use a custom pshost class to return it. I can't find any method or property in pshost that returns the exit code. This engine I have needs to ensure that script executes correctly. Any help would be appreciated. regards Bob. Its the $lastexitcode and the $? variables I need to bring back. Hi, Finally answered. I found out about the $host variable. It implements a callback into the host, specifically a custom PSHost object, enabling you to return the $lastexitcode. Here is a link to an explanation of $host. http://mshforfun.blogspot.com/2006/08/do-you-know-there-is-host-variable.html It seems to be obscure, badly documented, as usual with powershell docs. Using point 4, calling $host.SetShouldExit(1) returns 1 to the SetShouldExit method of pshost, as described here. http://msdn.microsoft.com/en-us/library/system.management.automation.host.pshost.setshouldexit(VS.85).aspx Its really depends on defining your own exit code defintion. 0 and 1 suffixes I guess. regards Bob.

• Multiple markers in Googe Maps API v3 that link to different pages when clicked

  - by Dave

  I have a map with multiple markers, which I populate via an array. Each marker is clickable and should take the user to a different url per marker. The problem is that all the markers, while displaying the correct title, all use the url of the last entry in the array. Here is my code: var myOptions = { zoom: 9, center: new google.maps.LatLng(40.81940575,-73.95647955), mapTypeId: google.maps.MapTypeId.TERRAIN } var map = new google.maps.Map(document.getElementById("bigmap"), myOptions); setMarkers(map, properties); var properties = [ ['106 Ft Washington Avenue',40.8388485,-73.9436015,'Mjg4'], ['213 Bennett Avenue',40.8574384,-73.9333426,'Mjkz'], ['50 Overlook Terrace',40.8543752,-73.9362542,'Mjky'], ['850 West 176 Street',40.8476012,-73.9417571,'OTM='], ['915 West End Avenue',40.8007478,-73.9692155,'Mjkx']]; function setMarkers(map, buildings) { var image = new google.maps.MarkerImage('map_marker.png', new google.maps.Size(19,32), new google.maps.Point(0,0), new google.maps.Point(10,32)); var shadow = new google.maps.MarkerImage('map_marker_shadow.png', new google.maps.Size(28,32), new google.maps.Point(0,0), new google.maps.Point(10,32)); var bounds = new google.maps.LatLngBounds; for (var i in buildings) { var myLatLng = new google.maps.LatLng(buildings[i][1], buildings[i][2]); bounds.extend(myLatLng); var marker = new google.maps.Marker({ position: myLatLng, map: map, shadow: shadow, icon: image, title: buildings[i][0] }); google.maps.event.addListener(marker, 'click', function() { window.location = ('detail?b=' + buildings[i][3]); }); } map.fitBounds(bounds); } Using this code, clicking any marker take the user to 'detail?b=Mjkx' What am I doing wrong?

• UISearchBar and UINavigationItem

  - by tbehunin

  I can't seem to get a UISearchBar to position itself from the far left to the far right in the navigation bar. In the -(void)viewDidLoad method, I have the following code: `UISearchBar *sb = [[UISearchBar alloc] initWithFrame:self.tableView.tableHeaderView.frame]; sb.delegate = self; self.navigationItem.titleView = sb; [sb sizeToFit]; [sb release];` When you build and run, it looks just fine at first glance. However, looking more closely, you can tell there is a margin/space on the left. This wouldn't be a big deal in the grand scheme of things, but when I tap the search bar to start a search, I animate the cancel button into view. Because the search bar is positioned slightly to the right, the animation is jerky and the cancel button falls off the end like so: link text It seems as if the UINavigationItem is like a table with three cells, where there is a padding on the first and last which I can't remove - nor does there seem to be a way to 'merge' it all together and then place the search bar there. I know this look is possible, because the AppStore search has a search bar in the navigation bar and it goes all the way to the edges. Anyone know how to get the search bar to go all the way to the edges so my slide-in cancel button animation will work properly?

• how does scrolling in android listview work?

  - by gartenkralleb

  hi, i have an android-app with a listview in an activity. the listview has, if i call it so, three data states. no data loaded from inet - only one dummy item is visible, saying that data is loading data is loaded and shown in list one listitem is clicked and now shows more information for this listitem (so it is increased in its height) on every state change (1 - 2, 2 - 3) i call notifyDataSetChanged() on this ListAdapater. this causes the listview to scroll down to the last item. this is ugly in the first transition and even more ugly in the second because the clicked list item is now out of focus. as i can see, this happens with a google g1 with android 1.6. a htc touch with the same sdk acts like desired (i try to figure it out with some more devices). to avoid this i tried to read out getScrollY() and set this value back. but this returns 0. the reason for this return value i already found on stackoverflow in other qutestions. does anyone else comes along with my problem so far? why does the listview scrolls to the last item? it was mentioned, that listview does keep track on the scroll position. but it seems that it does not in my case. or may i call the wrong refresh method? is notifyDataSetChanged the correct one?

• How can I put multiple markers on Google maps with Javascript API v3?

• Google Map API v3 — set bounds and center

  - by Michael Bradley

  Hi, I've recently switched to Google Maps API V3. I'm working of a simple example which plots markers from an array, however I do not know how to center and zoom automatically with respect to the markers. I've searched the net high and low, including Google's own documentation, but have not found a clear answer. I know I could simply take an average of the co-ordinates, but how would I set the zoom accordingly? Could somebody please point me in the right direction? Perhaps you know of a good tutorial. Many thanks in advance, Michael function initialize() { var myOptions = { zoom: 10, center: new google.maps.LatLng(-33.9, 151.2), mapTypeId: google.maps.MapTypeId.ROADMAP } var map = new google.maps.Map(document.getElementById("map_canvas"),myOptions); setMarkers(map, beaches); } var beaches = [ ['Bondi Beach', -33.890542, 151.274856, 4], ['Coogee Beach', -33.423036, 151.259052, 5], ['Cronulla Beach', -34.028249, 121.157507, 3], ['Manly Beach', -33.80010128657071, 151.28747820854187, 2], ['Maroubra Beach', -33.450198, 151.259302, 1] ]; function setMarkers(map, locations) { var image = new google.maps.MarkerImage('images/beachflag.png', new google.maps.Size(20, 32), new google.maps.Point(0,0), new google.maps.Point(0, 32)); var shadow = new google.maps.MarkerImage('images/beachflag_shadow.png', new google.maps.Size(37, 32), new google.maps.Point(0,0), new google.maps.Point(0, 32)); var lat = map.getCenter().lat(); var lng = map.getCenter().lng(); var shape = { coord: [1, 1, 1, 20, 18, 20, 18 , 1], type: 'poly' }; for (var i = 0; i < locations.length; i++) { var beach = locations[i]; var myLatLng = new google.maps.LatLng(beach[1], beach[2]); var marker = new google.maps.Marker({ position: myLatLng, map: map, shadow: shadow, icon: image, shape: shape, title: beach[0], zIndex: beach[3] }); } }

• jerky animation using Core Animation

  - by Paul from Boston

  In my iPhone app, I am trying to get some red and white stripes that are scrolling across the screen to animate smoothly when the speed of the stripes gets high. In my app the user starts the animation and changes the scrolling speed by a finger swipe and changes the width of the stripes by a two finger pinch. Animation is stopped in response to a double tap. If the speed gets high or the stripes get narrow the animation is no longer smooth to the eye. The edges of the stripes seem to jump around. The animation is simple. I draw the stripes in a layer that's a bit larger than the screen. I then set up an animation that moves the layer position by exactly the distance from one red stripe to the next. The duration is set by the speed of the finger swipe and the repeat count is 1. When the animation stops the delegate checks a flag to see if the user wants to stop the scrolling. If not, the animation is restarted again for one cycle. Are there better ways of doing this so that the animation is smooth at high speeds or with narrow stripes? Thanks--

  Background I'm trying to stream a wave file in Silverlight 4 using MediaStreamSource implementation found here. The problem is I want to play the file while it's still buffering, or at least give user some visual feedback while it's buffering. For now my code looks like that: private void button1_Click(object sender, RoutedEventArgs e) { HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri(App.Current.Host.Source, "../test.wav")); //request.ContentType = "audio/x-wav"; request.AllowReadStreamBuffering = false; request.BeginGetResponse(new AsyncCallback(RequestCallback), request); } private void RequestCallback(IAsyncResult ar) { this.Dispatcher.BeginInvoke(delegate() { HttpWebRequest request = (HttpWebRequest)ar.AsyncState; HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(ar); WaveMediaStreamSource wavMss = new WaveMediaStreamSource(response.GetResponseStream()); try { me.SetSource(wavMss); } catch (InvalidOperationException) { // This file is not valid } me.Play(); }); } The problem is that after settings request.AllowREadStreamBuffer to false the stream does not support seeking and the above mentioned implementation throws an exception (keep in mind I've put some of the position setting logic into if(stream.CanSeek) block): Read is not supported on the main thread when buffering is disabled Question Is there a way to play wav stream without buffering it in advance?

• Silverlight MergedDictionary - Attribute Value out of Range

  - by Wonko the Sane

  Hello All, I have a Silverlight-3 solution that contains a few different projects. I want to have one "common" project for holding controls and resources that will be used by multiple other projects. Within the common project, there is a folder called Resources, which holds a ResourceDictionary (CommonColors.xaml). This is set to be built as a Resource, Do Not Copy. I add a reference to the common project in another project (call it UncommonControls), and attempt to add the ResourceDictionary as a MergedDictionary: <UserControl.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/Common;component/Resources/CommonColors.xaml" /> <ResourceDictionary Source="/UncommonControls;component/Resources/UncommonStyles.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </UserControl.Resources> When I try to run, I get an exception: Attribute /Common;component/Resources/CommonColors.xaml value is out of range. [Line: 14 Position: 44] --- Inner Exception --- The given key was not present in the dictionary. However, if I reference a ResourceDictionary local to Uncommon (such as the UncommonStyles.xaml, above) project, which is set up with the same Build properties, it works fine. I haven't seen anything that says SL3 can't reference an external ResourceDictionary (on the contrary, I've seen an example of using one, albeit with no downloadable project to verify the behavior). Thanks, Wonko

• How to programmatically show & hide BalloonPopupExtender?

  - by Danferd

  I have a page that will be having few buttons that will redirect user to certain pages that required them to login before to proceed to the page. I would like to have something like, when user click on the button that required login and if user is not logged in prior to the click, a tooltip will show up beside the 'User ID' textbox to inform user to login in order to proceed. So, I implemented the jQuery Tooltipster in the page to show the tooltip message. I'm having problem on IE8 in Windows XP where the first click on the button, the tooltip would show up, but the second click it wouldn't then the third click, it shows up again and then the fourth click, it wouldn't! But for IE8 in Windows 7, IE9 & IE10, they have no such problem. Any idea how to fix this? The 'imgBtnKISS' & 'lnkBtnKISS' buttons are located in a content page but the tooltip and the 'User ID' textbox are in a master page. Below is the code that how I call the tooltip: function loginAlertMsg() { $('.tooltip').tooltipster({ trigger: 'custom', position: 'left', onlyOne: false, content: 'Login required! Please login to proceed.' }); $('#ctl00_txtID').tooltipster('show'); $('#ctl00_txtID').focus(); } Private Sub KISS_Click() Handles imgBtnKISS.Click, lnkBtnKISS.Click If Not bIsRefresh Then '==Detect User Login Status== Session(sesClickFromIcon) = toKISS If Session(USR.sesLogin) Is Nothing Then '//User NOT LOGIN. If (Not Page.ClientScript.IsStartupScriptRegistered("loginAlertMsg")) Then Page.ClientScript.RegisterStartupScript(Me.GetType(), "loginAlertMsg", "loginAlertMsg();", True) End If Exit Sub Else If Trim(CType(Session.Item(USR.sesLogin), Boolean)) <> True Then '//User NOT LOGIN. If (Not Page.ClientScript.IsStartupScriptRegistered("loginAlertMsg")) Then Page.ClientScript.RegisterStartupScript(Me.GetType(), "loginAlertMsg", "loginAlertMsg();", True) End If Exit Sub End If End If '**Detect User Login Status** Response.Redirect("~/page2.aspx", False) Session.Remove(sesClickFromIcon) End If End Sub

• Silverlight 4 WriteableBitmap ScaleTransform Exception but was working in v3

  - by Imran

  I am getting the following exception for code that used to work in silverlight 3 but has stopped working since upgrading to silverlight 4: System.AccessViolationException was unhandled Message=Attempted to read or write protected memory.

• Asp.net MVC Route class that supports catch-all parameter anywhere in the URL

  - by Robert Koritnik

  the more I think about it the more I believe it's possible to write a custom route that would consume these URL definitions: {var1}/{var2}/{var3} Const/{var1}/{var2} Const1/{var1}/Const2/{var2} {var1}/{var2}/Const as well as having at most one greedy parameter on any position within any of the upper URLs like {*var1}/{var2}/{var3} {var1}/{*var2}/{var3} {var1}/{var2}/{*var3} There is one important constraint. Routes with greedy segment can't have any optional parts. All of them are mandatory. Example This is an exemplary request http://localhost/Show/Topic/SubTopic/SubSubTopic/123/This-is-an-example This is URL route definition {action}/{*topicTree}/{id}/{title} Algorithm Parsing request route inside GetRouteData() should work like this: Split request into segments: Show Topic SubTopic SubSubTopic 123 This-is-an-example Process route URL definition starting from the left and assigning single segment values to parameters (or matching request segment values to static route constant segments). When route segment is defined as greedy, reverse parsing and go to the last segment. Parse route segments one by one backwards (assigning them request values) until you get to the greedy catch-all one again. When you reach the greedy one again, join all remaining request segments (in original order) and assign them to the greedy catch-all route parameter. Questions As far as I can think of this, it could work. But I would like to know: Has anyone already written this so I don't have to (because there are other aspects to parsing as well that I didn't mention (constraints, defaults etc.) Do you see any flaws in this algorithm, because I'm going to have to write it myself if noone has done it so far. I haven't thought about GetVirtuaPath() method at all.

• Android - Images from Assets folder in a GridView

  - by Saran

  Hi, I have been working on creating a Grid View of images, with images being present in the Assets folder. http://stackoverflow.com/questions/1933015/opening-an-image-file-inside-the-assets-folder link helped me with using the bitmap to read it. The code am currently having is: public View getView(final int position, View convertView, ViewGroup parent) { try { AssetManager am = mContext.getAssets(); String list[] = am.list(""); int count_files = imagelist.length; for(int i= 0;i<=count_files; i++) { BufferedInputStream buf = new BufferedInputStream(am.open(list[i])); Bitmap bitmap = BitmapFactory.decodeStream(buf); imageView.setImageBitmap(bitmap); buf.close(); } } catch (IOException e) { e.printStackTrace(); } } My application does read the image from the Assets folder, but it is not iterating through the cells in the grid view. All the cells of the grid view have a same image picked from the set of images. Can anyone tell me how to iterate through the cells and still have different images ? I have the above code in an ImageAdapter Class which extends the BaseAdapter class, and in my main class I am linking that with my gridview by: GridView gv =(GridView)findViewById(R.id.gridview); gv.setAdapter(new ImageAdapter(this, assetlist)); Thanks a lot for any help in advance, Saran

• How does Silverlight Image Clipping work?

  - by TreeUK

  I've got a very large image which I'd like to use for sprite techniques (à la css image sprites). I've got the code below: <Image x:Name="testImage" Width="24" Height="12" Source="../Resources/Images/sprites.png"> <Image.Clip> <RectangleGeometry Rect="258,10632,24,12" /> </Image.Clip> </Image> This clips the source image to 24x12 at the relative position of 258, 10632 in the source image. The problem is that I want the cropped image to show at 0,0 in the testImage whereas it shows it at 258, 10632. It's using the geometry as a cutting guide but also as a layout guide. Anyone have any idea how this should be done? if at all. Conclusion: There seems to be no good way of doing this at present, Graeme's solution seems to be the closest to achieving this with Silverlight 2.0. That said, if anyone knows of a better way of doing this, please reply with an answer.

• WCF service The maximum array length quota (16384) has been exceeded

  - by dmitry.baranovsky

  I have a wsf service and a client application. While trying to communicate the client and the service I've gotten the following message: "The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:blob. The InnerException message was 'There was an error deserializing the object of type FileBlob. The maximum array length quota (16384) has been exceeded while reading XML data. This quota may be increased by changing the MaxArrayLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 1, position 25931.'. Please see InnerException for more details." I have the customBinding element and it doesn't allow me to insert "readerQuotas" section. In both the client and service configs I have the following binding element: <customBinding> <binding name="LicenseServiceBinding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"> <security authenticationMode="UserNameOverTransport"> <localClientSettings maxClockSkew="00:07:00" /> <localServiceSettings maxClockSkew="00:07:00" /> </security> <windowsStreamSecurity /> <httpsTransport maxReceivedMessageSize="2147483646"/> </binding> </customBinding> Thanks in advance for any help:)
