• How to close and open access to SQL Server 2008 in Windows application?

  - by hgulyan

  Hi, I have a MS Access 97 application (but the question is general) working directly with SQL Server 2008 (without application server or anything). Numbers of users can be up to 1000. Windows Authentication is used. The question is: How to handle modes, so some users will be allowed to work in read-only mode some users won't have access to db for some time My versions: Using a table with a mode id for every group of users, that will work the same way. On Form Load application will query that table for mode id. Using trigger on the tables, that must work according to that mode. The trigger will query mode value and doesn't work if access is closed or it's in read-only mode I know these are not the best solutions, that's why I'm asking for your advice. There's one more point. If the mode is changed to "access-is-closed" for a group of users, that group must not be able to query to DB starting that moment. With first solution I wrote it won't work, because user can be in application at that moment and no form load event will work. How can I do this? Is there any optimal solution? Thank you. Any help would be appreciated.

• close other infowindows nicely.

  - by raklos

  Im currently doing this to create markers for my google map. function createMarker(posn, title, html) { var marker = new google.maps.Marker({ position: posn, title: title, draggable: false }); marker['infowindow'] = new google.maps.InfoWindow({ content: html }); infoWindows.push(marker['infowindow']); google.maps.event.addListener(marker, "click", function () { for (i = 0; i < infoWindows.length; i++) { infoWindows[i].close(); } this['infowindow'].open(map, this); }); return marker; } im not happy with the for loop, for closing the markers, i know something similar to this can be done by using one refernce: if (infowindow) infowindow.close(); the reason I am using code like above is because i am doing something like markers[myPoint]['infowindow'].open(map, markers[myPoint]); else where, (myPoint is a number). how can i avoid this for loop to close open infowindows and do it the nice way?

• Extra NotifyIcon shown in system tray

  - by Kettch19

  I'm having an issue with an app where my NotifyIcon displays an extra icon. The steps to reproduce it are easy, but the problem is that the extra icon shows up after any of the actual codebehind we've added fires. Put simply, clicking a button triggers execution of method FooBar() which runs all the way through fine but its primary duty is to fire a backgroundworker to log into another of our apps. It only appears if this particular button is clicked. Strangely enough, we have a WndProc method override and if I step through until the extra NotifyIcon appears, it always appears during this method so something else beyond the codebehind must be triggering the behavior. Our WndProc method is currently (although I don't think it's caused by the WndProc): Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message) 'Check for WM_COPYDATA message from other app or drag/drop action and handle message If m.Msg = NativeMethods.WM_COPYDATA Then ' get the standard message structure from lparam Dim CD As NativeMethods.COPYDATASTRUCT = m.GetLParam(GetType(NativeMethods.COPYDATASTRUCT)) 'setup byte array Dim B(CD.cbData) As Byte 'copy data from memory into array Runtime.InteropServices.Marshal.Copy(New IntPtr(CD.lpData), B, 0, CD.cbData) 'Get message as string and process ProcessWMCopyData(System.Text.Encoding.Default.GetString(B)) 'empty array Erase B 'set message result to 'true', meaning message handled m.Result = New IntPtr(1) End If 'pass on result and all messages not handled by this app MyBase.WndProc(m) End Sub The only place in the code where the NotifyIcon in question is manipulated at all is in the following event handler (again, don't think this is the culprit, but just for more info): Private Sub TrayIcon_MouseDoubleClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TrayIcon.MouseDoubleClick If Me.Visible Then Me.Hide() Else PositionBottomRight() Me.Show() End If End Sub The backgroundworker's DoWork is as follows (just a class call to log in to our other app, but again just for info): Private Sub LoginBackgroundWorker_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles LoginBackgroundWorker.DoWork Settings.IsLoggedIn = _wdService.LogOn(Settings.UserName, Settings.Password) End Sub Does anyone else have ideas on what might be causing this or how to possibly further debug this? I've been banging my head on this without seeing a pattern so another set of eyes would be extremely appreciated. :) I've posted this on MSDN winforms forums as well and have had no luck there so far either.

• Outlook VSTO AddIn for Meetings

  - by BigDubb

  We have created a VSTO addin for Outlook Meetings. As part of this we trap on the SendEvent of the message on the FormRegionShowing event: _apptEvents.Send += new Microsoft.Office.Interop.Outlook.ItemEvents_SendEventHandler(_apptEvents_Send); The method _apptEvents_Send then tests on a couple of properties and exits where appropriate. private void _apptEvents_Send(ref bool Cancel) { if (!_Qualified) { MessageBox.Show("Meeting has not been qualified", "Not Qualified Meeting", MessageBoxButtons.OK, MessageBoxIcon.Information); chkQualified.Focus(); Cancel = true; } } The problem that we're having is that some users' messages get sent twice. Once when the meeting is sent and a second time when the user re-opens outlook. I've looked for memory leaks, thinking that something might not be getting disposed of properly, and have added explicit object disposal on all finally calls to try and make sure resources are managed, but still getting the functionality incosistently across the organization. i.e. I never encountered the problem during development, nor other developers during testing. All users are up to date on framework (3.5 SP1) and Hotfixes for Outlook. Does anyone have any ideas on what might be causing this? Any ideas anyone might have would be greatly appreciated.

• Python: Calling method A from class A within class B?

  - by Tommo

  There are a number of questions that are similar to this, but none of the answers hits the spot - so please bear with me. I am trying my hardest to learn OOP using Python, but i keep running into errors (like this one) which just make me think this is all pointless and it would be easier to just use methods. Here is my code: class TheGUI(wx.Frame): def __init__(self, title, size): wx.Frame.__init__(self, None, 1, title, size=size) # The GUI is made ... textbox.TextCtrl(panel1, 1, pos=(67,7), size=(150, 20)) button1.Bind(wx.EVT_BUTTON, self.button1Click) self.Show(True) def button1Click(self, event): #It needs to do the LoadThread function! class WebParser: def LoadThread(self, thread_id): #It needs to get the contents of textbox! TheGUI = TheGUI("Text RPG", (500,500)) TheParser = WebParser TheApp.MainLoop() So the problem i am having is that the GUI class needs to use a function that is in the WebParser class, and the WebParser class needs to get text from a textbox that exists in the GUI class. I know i could do this by passing the objects around as parameters, but that seems utterly pointless, there must be a more logical way to do this that doesn't using classes seem so pointless? Thanks in advance!

• Need a Java based interruptible timer thread

  - by LambeauLeap

  I have a Main Program which is running a script on the target device(smart phone) and in a while loop waiting for stdout messages. However in this particular case, some of the heartbeat messages on the stdout could be spaced almost 45secs to a 1minute apart. something like: stream = device.runProgram(RESTORE_LOGS, new String[] {}); stream.flush(); String line = stream.readLine(); while (line.compareTo("") != 0) { reporter.commentOnJob(jobId, line); line = stream.readLine(); } So, I want to be a able to start a new interruptible thread after reading line from stdout with a required a sleep window. Upon being able to read a new line, I want to be able to interrupt/stop(having trouble killing the process), handle the newline of stdout text and restart a process. And it the event I am not able to read a line within the timer window(say 45secs) I want to a way to get out of my while loop either. I already tried the thread.run, thread.interrupt approach. But having trouble killing and starting a new thread. Is this the best way out or am I missing something obvious?

• File IO with Streams - Best Memory Buffer Size

  - by AJ

  I am writing a small IO library to assist with a larger (hobby) project. A part of this library performs various functions on a file, which is read / written via the FileStream object. On each StreamReader.Read(...) pass, I fire off an event which will be used in the main app to display progress information. The processing that goes on in the loop is vaired, but is not too time consuming (it could just be a simple file copy, for example, or may involve encryption...). My main question is: What is the best memory buffer size to use? Thinking about physical disk layouts, I could pick 2k, which would cover a CD sector size and is a nice multiple of a 512 byte hard disk sector. Higher up the abstraction tree, you could go for a larger buffer which could read an entire FAT cluster at a time. I realise with today's PC's, I could go for a more memory hungry option (a couple of MiB, for example), but then I increase the time between UI updates and the user perceives a less responsive app. As an aside, I'm eventually hoping to provide a similar interface to files hosted on FTP / HTTP servers (over a local network / fastish DSL). What would be the best memory buffer size for those (again, a "best-case" tradeoff between perceived responsiveness vs. performance).

• [jQuery UI - Accordion] Styling active header?

  - by RC

  Hi, Simple issue: I am using Accordion without any UI themes (just barebones, using my own CSS). So far, so good, except that I cannot figure out how to set an "active" style for the currently selected header. The jQuery code: $("#menu").accordion({ event:"mouseover",header:"a.top" }); The HTML code: <a href="#" class="top">XXX1</a> <div class="sub"> <a href="#">Subheading 1</a> <a href="#">Subheading 2</a> <a href="#">Subheading 3</a> </div> <a href="#" class="top">XXX2</a> <div class="sub"> <a href="#">Subheading 1</a> <a href="#">Subheading 2</a> <a href="#">Subheading 3</a> </div> This works great, except that I cannot find a way to define the styles for the active header without using ThemeRoller. Manually setting the following styles in my CSS has no effect: .ui-state-active .ui-widget-content .ui-state-active .ui-state-active a .ui-state-active a:link .ui-state-active a:visited Assistance, please?

• Updating a C# 2.0 events example to be idiomatic with C# 3.5?

  - by Damien Wildfire

  I have a short events example from .NET 2.0 that I've been using as a reference point for a while. We're now upgrading to 3.5, though, and I'm not clear on the most idiomatic way to do things. How would this simple events example get updated to reflect idioms that are now available in .NET 3.5? // Args class. public class TickArgs : EventArgs { private DateTime TimeNow; public DateTime Time { set { TimeNow = value; } get { return this.TimeNow; } } } // Producer class that generates events. public class Metronome { public event TickHandler Tick; public delegate void TickHandler(Metronome m, TickArgs e); public void Start() { while (true) { System.Threading.Thread.Sleep(3000); if (Tick != null) { TickArgs t = new TickArgs(); t.Time = DateTime.Now; Tick(this, t); } } } } // Consumer class that listens for events. public class Listener { public void Subscribe(Metronome m) { m.Tick += new Metronome.TickHandler(HeardIt); } private void HeardIt(Metronome m, TickArgs e) { System.Console.WriteLine("HEARD IT AT {0}",e.Time); } } // Example. public class Test { static void Main() { Metronome m = new Metronome(); Listener l = new Listener(); l.Subscribe(m); m.Start(); } }

• Chrome Extension - Console Log not firing

  - by coffeemonitor

  I'm starting to learn to make my own Chrome Extensions, and starting small. At the moment, I'm switching from using the alert() function to console.log() for a cleaner development environment. For some reason, console.log() is not displaying in my chrome console logs. However, the alert() function is working just fine. Can someone review my code below and perhaps tell me why console.log() isn't firing as expected? manifest.json { "manifest_version": 2, "name": "Sandbox", "version": "0.2", "description": "My Chrome Extension Playground", "icons": { "16": "imgs/16x16.png", "24": "imgs/24x24.png", "32": "imgs/32x32.png", "48": "imgs/48x48.png" }, "background": { "scripts": ["js/background.js"] }, "browser_action": { "default_title": "My Fun Sandbox Environment", "default_icon": "imgs/16x16.png" }, "permissions": [ "background", "storage", "tabs", "http://*/*", "https://*/*" ] } js/background.js function click(e) { alert("this alert certainly shows"); console.log("But this does not"); } // Fire a function, when icon is clicked chrome.browserAction.onClicked.addListener(click); As you can see, I kept it very simple. Just the manifest.json and a background.js file with an event listener, if the icon in the toolbar is clicked. As I mentioned, the alert() is popping up nicely, while the console.log() appears to be ignored.

• Clarification/explanation of RegisterClientScriptInclude method

  - by mpminnich

  I've been looking on the Internet for a fairly clear explanation of the different methods of registering javascript in an asp.net application. I think I have a basic understating of the difference between registerStartupScript and registerClientScriptBlock (the main difference being where in the form the script is inserted). I'm not sure I understand what the RegisterClientScriptInclude method does or when it is used. From what I can gather, it is used to register an external .js file. Does this then make any and all javascript functions in that file available to the aspx page it was registered on? For example, if it was registered in the onLoad event of a master page, would all pages using that master page be able to use the javascript functions in the .js file? What problems would arise when trying to use document.getElementById in this case, if any? Also, when it is necessary/advantageous to use multiple .js files and register them separately? I appreciate any help you can give. If you know of any really good resources I can use to get a thorough understanding of this concept, I'd appreciate it!

• Have a clickable button on top of a combobox in WPF

  - by Travyguy9

  I can get a button to appear and be clickable in the drop down list of a combo box, but I cannot get the selected combo box item (the drop list is closed) to have the button be clickable. It always skips the button click and just opens the drop down list. I basically want the Button_Click event handler that I setup to be called once it is clicked. Here is my sample combo box that shows the button but is not clickable once it is in the selected item: <ComboBox x:Name="MyCombo" Width="200" Height="30" ItemsSource="{Binding ListCombo}"> <ComboBox.Resources> <DataTemplate DataType="{x:Type local:ComboItemClass}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=SampleText}" Width="120" /> <Button Width="20" Content="..." Click="Button_Click"/> </StackPanel> </DataTemplate> </ComboBox.Resources> </ComboBox>

• Error while closing SQL Connection

  - by Wickedman84

  I have a problem with closing the SQLconnection in my application. My application is in VB.net. I have a reference in my application to a class with code to open and close the database connection and to execute all sql scripts. The error occurs when i close my application. In the formClosing event of my main form I call a function that closes all the connections. But just before I close the connections I perform an SQLquery to delete a row from a table with the function below. Public Function DeleteFunction(ByVal mySQLQuery As String, ByVal cmd As SqlCommand) As Boolean Try cmd.Connection = myConnection cmd.CommandText = mySQLQuery cmd.ExecuteNonQuery() Return True Catch ex As Exception WriteErrorMessage("DeleteFunction", ex, Logpath, "SQL Error: " & mySQLQuery) Return False End Try End Function In my application I check the result of the boolean. If it returns True, then i call the function to close the database connection. The returned boolean is True and the requested row is deleted in my database. This means i can close my connection which I do with the function below. Public Sub DatabaseConnClose() myCommand.CommandText = "" myConnection.Close() myCommand = Nothing myConnection = Nothing End Sub After executing this code I receive an error in my logfile from the DeleteFunction. It says: "Connection property has not been initialized." It seems very strange to receive an error from a function that was completely executed, or am i wrong to think that? Can anyone tell me why I receive this error and how I can solve the problem?

• Javafx Layout problem with VBox & HBoxes

  - by pgpatrudu

  When I run the following, I noticed spacing between nodes; My research revealed that - 1) If I do not add any text to win1 via setwininfo, then there is no problem. 2) When I include this code in a larger app, and when a button click is reveived from some where else, mysteriously the spacing gets corrected. 3) I tried binding the win1 & win2 nodes to content of scene - but no luck. def mainframew : Integer = 250; def mainframeh : Integer = 500; class CtrlWindow extends CustomNode { var wininfo : String; var fsize : Integer; var width : Integer; public function setWinInfo(info : String) { wininfo = info; } override protected function create () : Node { var win = Group { content: [ VBox { content: [ Text { font : Font { size: fsize } content : bind wininfo textAlignment : TextAlignment.CENTER // did not work } ] } Rectangle { width: width, height: 25 fill: Color.TRANSPARENT strokeWidth : 2 stroke : Color.SILVER } ] } return win; } } public function run(args : String[]) { var win1 = CtrlWindow{fsize:14, width:mainframew}; var win2 = CtrlWindow{fsize:14, width:mainframew}; win1.setWinInfo("The spacing between these nodes"); win2.setWinInfo("corrects itself after receiving an event"); Stage { title : "MyApp" scene: Scene { width: mainframew height: mainframeh content: [ VBox { spacing: 0 content: [ HBox { content: win1 } HBox { content: win2 } ] } ] } }

• SOAP and NHibernate Session in C#

  - by Anonymous Coward

  In a set of SOAP web services the user is authenticated with custom SOAP header (username/password). Each time the user call a WS the following Auth method is called to authenticate and retrieve User object from NHibernate session: [...] public Services : Base { private User user; [...] public string myWS(string username, string password) { if( Auth(username, password) ) { [...] } } } public Base : WebService { protected static ISessionFactory sesFactory; protected static ISession session; static Base { Configuration conf = new Configuration(); [...] sesFactory = conf.BuildSessionFactory(); } private bool Auth(...) { session = sesFactory.OpenSession(); MembershipUser user = null; if (UserCredentials != null && Membership.ValidateUser(username, password)) { luser = Membership.GetUser(username); } ... try { user = (User)session.Get(typeof(User), luser.ProviderUserKey.ToString()); } catch { user = null; throw new [...] } return user != null; } } When the WS work is done the session is cleaned up nicely and everything works: the WSs create, modify and change objects and Nhibernate save them in the DB. The problems come when an user (same username/password) calls the same WS at same time from different clients (machines). The state of the saved objects are inconsistent. How do I manage the session correctly to avoid this? I searched and the documentation about Session management in NHibernate is really vast. Should I Lock over user object? Should I set up a "session share" management between WS calls from same user? Should I use Transaction in some savvy way? Thanks Update1 Yes, mSession is 'session'. Update2 Even with a non-static session object the data saved in the DB are inconsistent. The pattern I use to insert/save object is the following: var return_value = [...]; try { using(ITransaction tx = session.Transaction) { tx.Begin(); MyType obj = new MyType(); user.field = user.field - obj.field; // The fields names are i.e. but this is actually what happens. session.Save(user); session.Save(obj); tx.Commit(); return_value = obj.another_field; } } catch ([...]) { // Handling exceptions... } finally { // Clean up session.Flush(); session.Close(); } return return_value; All new objects (MyType) are correctly saved but the user.field status is not as I would expect. Even obj.another_field is correct (the field is an ID with generated=on-save policy). It is like 'user.field = user.field - obj.field;' is executed more times then necessary.

• Implementations details of drag and drop of file path in cocoa.

  - by foo

  Hi, I'm trying to get a part of my window to react to drag and drop. In this case to copy the file path to the file being dropped on the view. I have looked over some documentation but I still have some problems to see exactly where I should implement my methods for drag and drop. I have seen some examples but almost all of them assumes that I want to drop an image on the view. I'm pretty new to cocoa and Xcode so, I have some problems with seeing the exact relation between interface builder and the generated code. I have created a subclass to NSView, called drop zone like this: #import <Cocoa/Cocoa.h> @interface dropZone : NSView { } @end I then use an NSRect to color it grey like this: #import "dropZone.h" @implementation dropZone - (void)drawRect:(NSRect)rect { NSRect bounds = [self bounds]; [[NSColor grayColor] set]; [NSBezierPath fillRect:bounds]; } @end I then drag this class to my window in interface builder. But I will need to implement the registerForDraggingTypes method, but where? I have also seen a convenience method in the Apple docs for file paths like this: dragFile:fromRect:slideBack:event: that might work.

• How to focus a control in an MDIParent when all child windows have closed?

  - by Tim Gradwell

  I have a control in my parent mdi form which I wish to be given the focus if all mdi children have closed. I've tried hooking into the child form's FormClosed event and setting the focus from there but when I test it, my control is not left with focus when I close the mdi child. Can anyone tell me what I'm missing? In the sample below, "first focus" gets hit and does its job correctly (if I comment out the first focus line, my tree does not get focus on startup, so it must be doing its job, right?) Unfortunately, even though "second focus" gets hit, my tree does not end up with the focus when I close the child window. Sample using System; using System.Windows.Forms; namespace mdiFocus { class ParentForm : Form { public ParentForm() { IsMdiContainer = true; tree = new TreeView(); tree.Nodes.Add("SomeNode"); tree.Dock = DockStyle.Left; Controls.Add(tree); } protected override void OnShown(EventArgs e) { Form child = new Form(); child.MdiParent = this; child.Show(); child.FormClosed += new FormClosedEventHandler(child_FormClosed); tree.Focus(); // first focus works ok } void child_FormClosed(object sender, FormClosedEventArgs e) { tree.Focus(); // second focus doesn't seem to work, even though it is hit :( } TreeView tree; } static class Program { [STAThread] static void Main() { Application.Run(new ParentForm()); } } }

• Set bounds for markers generated by jQuery table loop?

  - by abemonkey

  I have some jQuery code that goes through a table of location results and puts corresponding pins on a map. I am having trouble figuring out how to set the bounds so that when it goes through the loop and generates the markers on the map that it zooms and pans to fit the markers in the view. I've tried implementing code from some similar questions on this site but nothing seems to be working. Please let me know what code I should be using and where the heck I should put it in my script: $(function() { var latlng = new google.maps.LatLng(44, 44); var settings = { zoom: 15, center: latlng, disableDefaultUI: false, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $('tr').each(function(i) { var the_marker = new google.maps.Marker({ title: $(this).find('.views-field-title').text(), map: map, clickable: true, position: new google.maps.LatLng( parseFloat($(this).find('.views-field-latitude').text()), parseFloat($(this).find('.views-field-longitude').text()) ) }); var infowindow = new google.maps.InfoWindow({ content: $(this).find('.views-field-title').text() + $(this).find('.adr').text() }); new google.maps.event.addListener(the_marker, 'click', function() { infowindow.open(map, the_marker); }); }); }); `

• Windows Form UserControl design time properties

  - by Raffaeu

  I am struggling with a UserControl. I have a UserControl that represent a Pager and it has a Presenter object property exposed in this way: [Browsable(false)] [DesignSerializationAttribute(DesignSerializationAttribute.Hidden)] public object Presenter { get; set; } The code itself works as I can drag and drop a control into a Windows From without having Visual Studio initializing this property. Now, because in the Load event of this control I call a method of the Presenter that at run-time is null ... I have introduced this additional code: public override void OnLoad(...) { if (this.DesignMode) { base.OnLoad(e); return; } presenter.OnViewReady(); } Now, every time I open a Window that contains this UserControl, Visual Studio modifies the Windows designer code. So, as soon as I open it, VS ask me if I want to save it ... and of course, if I add a control to the Window, it doesn't keep the changes ... As soon as I remove the UserControl Pager the problem disappears ... How should I tackle that in the proper way? I just don't want that the presenter property is initialized at design time as it is injected at runtime ...

• Concatenate, sort and swap array in Java

  I am trying to concatenate two arrays into new array, sort in order, and swap two values of index. I'm kind of new to java and only use C before so having a hard time handling an Object. In main method it declares two object arrays IntVector vector = new IntVector(3); and IntVector vector2 = new IntVector(3); I can only do this if the types are int[], but I want to use as an object How should I code the concat, sort, and swap method? public class IntVector { private int[] items_; private int itemCount_; private IntVector(int[] data, int n) { items_ = data.clone(); itemCount_ = n; } public IntVector(int itemSize) { itemCount_ =0; if(itemSize<1) itemSize =10; items_ = new int[itemSize]; } public void push(int value) { if(itemCount_ + 1 >= items_.length) overflow(); items_[itemCount_++] = value; } public void log() { for (int i=0 ; i<itemCount_; ++i) { System.out.print(items_[i]); if(i<itemCount_ -1) System.out.println(); } } public void overflow() { int[] newItems = new int[items_.length * 2]; for(int i=0 ; i<itemCount_; ++i) { newItems[i] = items_[i]; } items_=newItems; } public int getValue(int index) { if(index < 0 || index >= itemCount_) { System.out.println("[error][IntVector][setValue] Incorrect index=" + index); return 0; } return items_[index]; } public void setValue(int index, int value) { if(index < 0 || index >= itemCount_) { System.out.println("[error][IntVector][setValue] Incorrect index=" + index); return ; } items_[index] = value; } public IntVector clone() { return new IntVector(items_, itemCount_); } public IntVector concat() { return null; } public IntVector sort() { return null; } public IntVector swap() { return null; } public static void main(String[] args) { IntVector vector = new IntVector(3); IntVector vector2 = new IntVector(3); vector.push(8); vector.push(200); vector.push(3); vector.push(41); IntVector cloneVector = vector.clone(); vector2.push(110); vector2.push(12); vector2.push(7); vector2.push(141); vector2.push(-32); IntVector concatResult = vector.concat(vector2); IntVector sortResult = concatResult.sort(); IntVector swapResult = sortResult.clone(); //swapResult.swap(1,5); System.out.print("vector : "); vector.log(); System.out.print("\n\ncloneVector : "); cloneVector.log(); System.out.print("\n\nvector2 : "); vector2.log(); System.out.print("\n\nconcatvector : "); concatResult.log(); System.out.print("vector : "); vector.log(); System.out.print("vector : "); vector.log(); } }

• Testing Web Application: "Mirror" ad-hoc testing in another window

  - by Narcissus

  I don't even really know if the title is the best way to explain what I'm trying to do, but anyway... We have a web app that is being ported to a number of DB backends via MDB2. Our unit tests are pretty lacking at the moment, but our internal users are pretty good at knowing what to test to see if things are broken. What I'm 'imagining' is a browser plug in (don't really care which browser it is for) or a similar system that essentially takes every event from one window and 'mirrors' it in the other browser/s. The reason I'd like this is so that I can have various installations that use different DB backends, and have the user open a window/tab to each installation. From there, however, I'd like them to be able to 'work' in one window and have that 'work' I occur at the same time in each of the 'cloned' windows. From there, they should be able to do some quick eyeballing of the information that comes back, without having to worry about timing differences and so (very much). I know it's a big ask, but I figure if anyone knows of a solution, I'd find it here... Any thoughts?

• gwt get array button value

  - by graybow

  My gwt project have flexTable show data of image and button on each row and coll. But my button won't work properly. this is my current code: private Button[] b = new Button[]{new Button("a"),...,new Button("j")}; private int z=0; ... public void UpdateTabelGallery(JsArray str){ for(int i=0; i str.length(); i++){ b[i].setText(str.gettitle()); UpdateTabelGallery(str.get(i)); } } public void UpdateTabelGallery(GalleryData str){ Image img = new Image(); img.setUrl(str.getthumburl()); HTML himage= new HTML("a href="+str.geturl()+""+ img +"/a" + b[z] ); TabelGaleri.setWidget(y, x, himage); //is here th right place? b[z].addClickHandler(new ClickHandler(){ @Override public void onClick(ClickEvent event) { Window.alert("I wan to show the clicked button text" + b[z].getText()); } }); z++; } I'm still confuse where I should put my button handler. With this current code seems the clickhandler didn't work inside a looping. And if I put it outside loop its not working because I need to know which button clicked. I need to get my index button.but how? Is there any option than array button? thanks

• jQuery UI Dialog Issue With IE

  - by Dan Appleyard

  I am using the new jQuery 1.3.2 and jQuery-ui-1.7 libraries along with the UI Dialog. I have a div tag with several form elements (textbox, checkbox, etc.) in it. Upon page load, jQuery shows the div as a dialog. This works absolutely fine in FF, but in IE, the height of the div is wrong. It is just showing the title bar a bit of the content. I explicitly set the height when creating the div. If I set the height option after opening the dialog, the height is corrected, but the content is blank (shows the top third of a textbox). If I allow the dialog to be resizable, if you resize it in IE it works fine, but I don't want to force IE users to resize just to see the contents. Any ideas? Here is the code I use to create the dialog: $('#dialogDiv').dialog({ bgiframe: true, height: 400, width: 620, modal: true, draggable: true, resizable: false, close: function(event, ui) { if($('#agree').val() != '1') location.href = 'somepage.html'; } });
