  • Pasting formatted Excel range into Outlook message

    - by Steph
    Hi everyone, I am using Office 2007 and I would like to use VBA to paste a range of formatted Excel cells into an Outlook message and then mail the message. In the following code (that I lifted from various sources), it runs without error and then sends an empty message... the paste does not work. Can anyone see the problem and better yet, help with a solution? Thanks, -Steph Sub SendMessage(SubjectText As String, Importance As OlImportance) Dim objOutlook As Outlook.Application Dim objOutlookMsg As Outlook.MailItem Dim objOutlookRecip As Outlook.Recipient Dim objOutlookAttach As Outlook.Attachment Dim iAddr As Integer, Col As Integer, SendLink As Boolean 'Dim Doc As Word.Document, wdRn As Word.Range Dim Doc As Object, wdRn As Object ' Create the Outlook session. Set objOutlook = CreateObject("Outlook.Application") ' Create the message. Set objOutlookMsg = objOutlook.CreateItem(olMailItem) Set Doc = objOutlookMsg.GetInspector.WordEditor 'Set Doc = objOutlookMsg.ActiveInspector.WordEditor Set wdRn = Doc.Range wdRn.Paste Set objOutlookRecip = objOutlookMsg.Recipients.Add("[email protected]") objOutlookRecip.Type = 1 objOutlookMsg.Subject = SubjectText objOutlookMsg.Importance = Importance With objOutlookMsg For Each objOutlookRecip In .Recipients objOutlookRecip.Resolve ' Set the Subject, Body, and Importance of the message. '.Subject = "Coverage Requests" 'objDrafts.GetFromClipboard Next .Send End With Set objOutlookMsg = Nothing Set objOutlook = Nothing End Sub

  • Transforming coordinates from an image control to the image source in WPF

    - by Gabriel
    I'm trying to learn WPF, so here's a simple question, I hope: I have a window that contains an Image element bound to a separate data object with user-configurable Stretch property <Image Name="imageCtrl" Source="{Binding MyImage}" Stretch="{Binding ImageStretch}" /> When the user moves the mouse over the image, I would like to determine the coordinates of the mouse with respect to the original image (before stretching/cropping that occurs when it is displayed in the control), and then do something with those coordinates (update the image). I know I can add an event-handler to the MouseMove event over the Image control, but I'm not sure how best to transform the coordinates: void imageCtrl_MouseMove(object sender, MouseEventArgs e) { Point locationInControl = e.GetPosition(imageCtrl); Point locationInImage = ??? updateImage(locationInImage); } Now I know I could compare the size of Source to the ActualSize of the control, and then switch on imageCtrl.Stretch to compute the scalars and offsets on X and Y, and do the transform myself. But WPF has all the information already, and this seems like functionality that might be built-in to the WPF libraries somewhere. So I'm wondering: is there a short and sweet solution? Or do I need to write this myself? EDIT I'm appending my current, not-so-short-and-sweet solution. Its not that bad, but I'd be somewhat suprised if WPF didn't provide this functionality automatically: Point ImgControlCoordsToPixelCoords(Point locInCtrl, double imgCtrlActualWidth, double imgCtrlActualHeight) { if (ImageStretch == Stretch.None) return locInCtrl; Size renderSize = new Size(imgCtrlActualWidth, imgCtrlActualHeight); Size sourceSize = bitmap.Size; double xZoom = renderSize.Width / sourceSize.Width; double yZoom = renderSize.Height / sourceSize.Height; if (ImageStretch == Stretch.Fill) return new Point(locInCtrl.X / xZoom, locInCtrl.Y / yZoom); double zoom; if (ImageStretch == Stretch.Uniform) zoom = Math.Min(xZoom, yZoom); else // (imageCtrl.Stretch == Stretch.UniformToFill) zoom = Math.Max(xZoom, yZoom); return new Point(locInCtrl.X / zoom, locInCtrl.Y / zoom); }

  • How to avoid timeouts in WCF?

    - by Jader Dias
    I use netNamedPipeBinding, and my service methods return nothing (void), but they timeout: TimeoutException: "The open operation did not complete within the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout." Server stack trace: at System.ServiceModel.Channels.ClientFramingDuplexSessionChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.CallOnceManager.CallOnce(TimeSpan timeout, CallOnceManager cascade) at System.ServiceModel.Channels.ServiceChannel.EnsureOpened(TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation) at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message) Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) To avoid this I turned my service into a OneWay operation. But the timeout still occurs. I expected that it solved my problem. Its the netMsmqBinding the only one that could avoid such timeout? I also tried to make all processing in a separate thread, so the service can disconnect earlier, with no success.

  • Flex AdvancedDataGrid - ColumnOrder With Formatter and ItemRenderer Question For Experts

    - by robin1126
    I have a advanceddatagrid that has around 15 columns. Some are string, some are numbers. I have shown 4 columns below. The number columns have formatting done for zero precision and 2 digits precision. The itemRenderer is just to show Blue Color if the number is +ve and Red Color if the number is -ve. It looks something like below ... I am trying to save the users setting of column order when he closes the application and reload with the same order when the user opens the applications. I am using SharedObjects and below is the code. for(var i:int=0; i< adgrid.columns.length;i++){ var columnObject:Object = new Object(); columnObject.columnDataField = adgrid.columns[i].dataField as String; columnObject.columnHeader =adgrid.columns[i].headerText as String; columnObject.width = adgrid.columns[i].width; columnArray.push(columnObject); } and then I save the columnArray to SharedObject. I retrive them using the below code for(var i:int=0;i adgrid.columns[i].dataField =columnArray[i].columnDataField; adgrid.columns[i].headerText =columnArray[i].columnHeader; adgrid.columns[i].width = columnArray[i].width; } How can I save and reload the Formatter and ItemRenderer data . I am having trouble saving the formatter and itemrenderer and reloading it again. I would really appreciate if you can shown the code. How can I reshuffle the columns but can preserve all the properties of it to the sharedobject and recover it again.

  • Embed Youtube in UIWebView behind transparent img. Wmode transparent and z-index doesn't work

    - by Allisone
    I'm using this code: - (void)embedYouTube:(NSString *)urlString frame:(CGRect)frame { NSString *embedHTML = @"\ <html><head>\ <style type=\"text/css\">\ body {\ background-color: black;\ }\ #container{\ position: relative;\ z-index:1;\ }\ #video,#videoc{\ position:absolute;\ z-index: 1;\ border: none;\ }\ #tv{\ background: transparent url(tv.png) no-repeat;\ width: 320px;\ height: 205px;\ position: absolute;\ top: 0;\ z-index: 999;\ }\ </style>\ </head><body style=\"margin:0\">\ <div id=\"tv\"></div>\ <object id=\"videoc\" width=\"240\" height=\"160\">\ <param name=\"movie\" value=\"%@\"></param>\ <param name=\"wmode\" value=\"transparent\"></param>\ <embed wmode=\"transparent\" id=\"video\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"240\" height=\"160\"></embed>\ </object>\ </body></html>"; NSString *path = [[NSBundle mainBundle] bundlePath]; NSURL *baseURL = [NSURL fileURLWithPath:path]; NSString *html = [NSString stringWithFormat:embedHTML, urlString,urlString]; UIWebView *videoView = [[UIWebView alloc] initWithFrame:frame]; [videoView loadHTMLString:html baseURL:baseURL]; [self.view addSubview:videoView]; [videoView release]; } Its the first time that I use UIWebView and the first time that I use video in iPhone. The video plays, so that's working BUT: I want to have an old school tv (round corners) in foreground with switches and so on. The tv is an image with transparent pixels in the middle, so that a video lying behind the tv will shine through as if the video would be shown on the tv. But first of all the video has a border that I can't remove and second it's always in the foreground. In Safari and in Firefox and Mac it's working. So is it an iPhone thing, could it be that it simply won't work on iPhone ? Or do I have some css/html typos ?

  • Enumerating all strings in resx

    - by Erik Hesselink
    We would like to enumerate all strings in a resource file in .NET (resx file). We want this to generate a javascript object containing all these key-value pairs. We do this now for satellite assemblies with code like this (this is VB.NET, but any example code is fine): Dim rm As ResourceManager rm = New ResourceManager([resource name], [your assembly]) Dim Rs As ResourceSet Rs = rm.GetResourceSet(Thread.CurrentThread.CurrentCulture, True, True) For Each Kvp As DictionaryEntry In Rs [Write out Kvp.Key and Kvp.Value] Next However, we haven't found a way to do this for .resx files yet, sadly. How can we enumerate all localization strings in a resx file? UPDATE: Following Dennis Myren's comment and the ideas from here, I built a ResXResourceManager. Now I can do the same with .resx files as I did with the embedded resources. Here is the code. Note that Microsoft made a needed constructor private, so I use reflection to access it. You need full trust when using this. Imports System.Globalization Imports System.Reflection Imports System.Resources Imports System.Windows.Forms Public Class ResXResourceManager Inherits ResourceManager Public Sub New(ByVal BaseName As String, ByVal ResourceDir As String) Me.New(BaseName, ResourceDir, GetType(ResXResourceSet)) End Sub Protected Sub New(ByVal BaseName As String, ByVal ResourceDir As String, ByVal UsingResourceSet As Type) Dim BaseType As Type = Me.GetType().BaseType Dim Flags As BindingFlags = BindingFlags.NonPublic Or BindingFlags.Instance Dim Constructor As ConstructorInfo = BaseType.GetConstructor(Flags, Nothing, New Type() { GetType(String), GetType(String), GetType(Type) }, Nothing) Constructor.Invoke(Me, Flags, Nothing, New Object() { BaseName, ResourceDir, UsingResourceSet }, Nothing) End Sub Protected Overrides Function GetResourceFileName(ByVal culture As CultureInfo) As String Dim FileName As String FileName = MyBase.GetResourceFileName(culture) If FileName IsNot Nothing AndAlso FileName.Length > 10 Then Return FileName.Substring(0, FileName.Length - 10) & ".resx" End If Return Nothing End Function End Class

  • RhinoMocks Testing callback method

    - by joblot
    Hi All I have a service proxy class that makes asyn call to service operation. I use a callback method to pass results back to my view model. Doing functional testing of view model, I can mock service proxy to ensure methods are called on the proxy, but how can I ensure that callback method is called as well? With RhinoMocks I can test that events are handled and event raise events on the mocked object, but how can I test callbacks? ViewModel: public class MyViewModel { public void GetDataAsync() { // Use DI framework to get the object IMyServiceClient myServiceClient = IoC.Resolve<IMyServiceClient>(); myServiceClient.GetData(GetDataAsyncCallback); } private void GetDataAsyncCallback(Entity entity, ServiceError error) { // do something here... } } ServiceProxy: public class MyService : ClientBase, IMyServiceClient { // Constructor public NertiAdminServiceClient(string endpointConfigurationName, string remoteAddress) : base(endpointConfigurationName, remoteAddress) { } // IMyServiceClient member. public void GetData(Action<Entity, ServiceError> callback) { Channel.BeginGetData(EndGetData, callback); } private void EndGetData(IAsyncResult result) { Action<Entity, ServiceError> callback = result.AsyncState as Action<Entity, ServiceError>; ServiceError error; Entity results = Channel.EndGetData(out error, result); if (callback != null) callback(results, error); } } Thanks

  • Cannot get assembly version for footer

    - by Jaxidian
    I'm using the automatic build versioning mentioned in this question (not the selected answer but the answer that uses the [assembly: AssemblyVersion("1.0.*")] technique). I'm doing this in the footer of my Site.Master file in MVC 2. My code for doing this is as follows: <div id="footer"> <a href="emailto:[email protected]">[email protected]</a> - Copyright © 2005-<%= DateTime.Today.Year.ToString() %>, foo LLC. All Rights Reserved. - Version: <%= Assembly.GetEntryAssembly().GetName().Version.ToString() %> </div> The exception I get is a Object reference not set to an instance of an object because GetEntryAssembly() returns NULL. My other options don't work either. GetCallingAssembly() always returns "4.0.0.0" and GetExecutingAssembly() always returns "0.0.0.0". When I go look at my DLLs, everything is versioning as I would expect. But I cannot figure out how to access it to display in my footer!!

  • Problem with Java Applet <--> Javascript communication

    - by davr
    I'm having trouble getting a Java Applet to communicate with the Javascript code on the page the applet is hosted on. It works sometimes, but othertimes it throws an obscure exception, that googling for has not turned up any useful information, besides a few Java bug reports that were never resolved (thanks Sun). Here is the code I am using: JSObject win = JSObject.getWindow(this); Object[] args = new Object[1]; args[0] = "test argument"; String result = (String) win.call("testJSfunc", args); // XXX Here is the exception I get on the line marked // XXX. Note that it is intermittent. Often it works, but sometimes it does not, using the same exact code. Reloading the page repeatedly will produce the error pretty quickly. netscape.javascript.JSException: No registered plugin for applet ID 1 at sun.plugin2.main.client.MessagePassingJSObject.newJSException(Unknown Source) at sun.plugin2.main.client.MessagePassingJSObject.waitForReply(Unknown Source) at sun.plugin2.main.client.MessagePassingJSObject.call(Unknown Source) at TestApplet.testCallJS(TestApplet.java:159) at TestApplet.init(TestApplet.java:139) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Is there another more stable way of communicating between Java and Javascript that I should be using?

  • Rails.cache throws "marshal dump" error when changed from memory store to memcached store

    - by gsmendoza
    If I set this in my environment config.action_controller.cache_store = :mem_cache_store ActionController::Base.cache_store will use a memcached store but Rails.cache will use a memory store instead: $ ./script/console >> ActionController::Base.cache_store => #<ActiveSupport::Cache::MemCacheStore:0xb6eb4bbc @data=<MemCache: 1 servers, ns: nil, ro: false>> >> Rails.cache => #<ActiveSupport::Cache::MemoryStore:0xb78b5e54 @data={}> In my app, I use Rails.cache.fetch(key){ object } to cache objects inside my helpers. All this time, I assumed that Rails.cache uses the memcached store so I'm surprised that it uses memory store. If I change the cache_store setting in my environment to config.cache_store = :mem_cache_store both ActionController::Base.cache_store and Rails.cache will now use the same memory store, which is what I expect: $ ./script/console >> ActionController::Base.cache_store => #<ActiveSupport::Cache::MemCacheStore:0xb7b8e928 @data=<MemCache: 1 servers, ns: nil, ro: false>, @middleware=#<Class:0xb7b73d44>, @thread_local_key=:active_support_cache_mem_cache_store_local_cache> >> Rails.cache => #<ActiveSupport::Cache::MemCacheStore:0xb7b8e928 @data=<MemCache: 1 servers, ns: nil, ro: false>, @middleware=#<Class:0xb7b73d44>, @thread_local_key=:active_support_cache_mem_cache_store_local_cache> However, when I run the app, I get a "marshal dump" error in the line where I call Rails.cache.fetch(key){ object } no marshal_dump is defined for class Proc Extracted source (around line #1): 1: Rails.cache.fetch(fragment_cache_key(...), :expires_in => 15.minutes) { ... } vendor/gems/memcache-client-1.8.1/lib/memcache.rb:359:in 'dump' vendor/gems/memcache-client-1.8.1/lib/memcache.rb:359:in 'set_without_newrelic_trace' What gives? Is Rails.cache meant to be a memory store? Should I call controller.cache_store.fetch in the places where I call Rails.cache.fetch?

  • MATLAB Builder NE (.NET Assembly) Data type question

    - by Brett
    Hi coders, I am using MATLAB Builder NE (MATLAB's integrated .NET assmebly builder), but I am having an issue with data types. I have compiled a small, very simple, function in matlab and build it for .NET. I am able to call the namespace and even the function just fine. However, my function returns a value, and MATLAB defaults to returning it as an "object[]" data type. However, I know that the value is an integer, but I can't figure out how to cast it. My MATLAB function looks like this: function addValue = Myfunction(value1, value2) addValue=value1+value2; end Pretty simple right? And then in .NET I can call it as: xClass.addValue (1, 3, 4); where xClass is the name of the MATLAB built class but when I try: int x = xClass.addValue (1, 3, 4); C# errors out. Typical .NET casting (int) doesn't work. The compiler states it cannot convert object[] to int. Does anyone have experience with the .NET builder in MATLAB that can help me with this? It is really throwing me for a loop. I have scanned through most of the MATLAB BUILDER doc (484 pages!) with zero help. Thank you, Brett

    Is there any recommended coding style how to write PowerShell scripts? It's not about how to structure the code (how many functions, if to use module, ...). It's about 'how to write the code so that it is readable'. In programming languages there are some recommended coding styles (what to indent, how to indent - spaces/tabs, where to make new line, where to put braces,...), but I haven't seen any suggestion for PowerShell. What I'm interested particularly in: How to write parameters function New-XYZItem ( [string] $ItemName , [scriptblock] $definition ) { ... (I see that it's more like 'V1' syntax) or function New-PSClass { param([string] $ClassName ,[scriptblock] $definition )... or (why to add empty attribute?) function New-PSClass { param([Parameter()][string] $ClassName ,[Parameter()][scriptblock] $definition )... or (other formatting I saw maybe in Jaykul's code) function New-PSClass { param( [Parameter()] [string] $ClassName , [Parameter()] [scriptblock] $definition )... or ..? How to write complex pipeline Get-SomeData -param1 abc -param2 xyz | % { $temp1 = $_ 1..100 | % { Process-somehow $temp1 $_ } } | % { Process-Again $_ } | Sort-Object -desc or (name of cmdlet on new line) Get-SomeData -param1 abc -param2 xyz | % { $temp1 = $_ 1..100 | % { Process-somehow $temp1 $_ } } | % { Process-Again $_ } | Sort-Object -desc | and what if there are -begin -process -end params? how to make it the most readable? Get-SomeData -param1 abc -param2 xyz | % -begin { init } -process { Process-somehow2 ... } -end { Process-somehow3 ... } | % -begin { } .... or Get-SomeData -param1 abc -param2 xyz | % ` -begin { init } ` -process { Process-somehow2 ... } ` -end { Process-somehow3 ... } | % -begin { } .... the indentitation is important here and what element is put on new line as well. I have covered only questions that come on my mind very frequently. There are some others, but I'd like to keep this SO question 'short'. Any other suggestions are welcome.

  • Performance penalty of typecasting and boxing/unboxing types in C# when storing generic values

    - by kitsune
    I have a set-up similar to WPF's DependencyProperty and DependencyObject system. My properties however are generic. A BucketProperty has a static GlobalIndex (defined in BucketPropertyBase) which tracks all BucketProperties. A Bucket can have many BucketProperties of any type. A Bucket saves and gets the actual values of these BucketProperties... now my question is, how to deal with the storage of these values, and what is the penalty of using a typecasting when retrieving them? I currently use an array of BucketEntries that save the property values as simple objects. Is there any better way of saving and returning these values? Beneath is a simpliefied version: public class BucketProperty<T> : BucketPropertyBase { } public class Bucket { private BucketEntry[] _bucketEntries; public void SaveValue<T>(BucketProperty<T> property, T value) { SaveBucketEntry(property.GlobalIndex, value) } public T GetValue<T>(BucketProperty<T> property) { return (T)FindBucketEntry(property.GlobalIndex).Value; } } public class BucketEntry { private object _value; private uint _index; public BucketEntry(uint globalIndex, object value) { ... } }

  • WCF for a shared data access

    - by Audrius
    Hi all, I have a little experience with WCF and would like to get your opinion/suggestion on how the following problem can be solved: A web service needs to be accessible from multiple clients simultaneously and service needs to return a result from a shared data set. The concrete project I'm working on has to store a list of IP addresses/ranges. This list will be queried by a bunch of web servers for a validation purposes and we speak of a couple of thousand or more queries per minute. My initial draft approach was to use Windows service as a WCF host with service contract implementing class that is decorated with ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple) that has a list object and a custom locking for accessing it. So basically I have a WCF service singleton with a list = shared data - multiple clients. What I do not like about it is that data and communication layers are merged into one and performance wise this doesn't feel "right". What I really really (- want is Windows service running an instance of IP list holding container class object, a second service running WCF service contract implementation and a way the latter querying the former in a nice way with a minimal blocking. Using another WCF channel would not really take me far away from the initial draft implementation or would it? What approach would you take? Project is still in a very early stage so complete design re-do is not out of question. All ideas are appreciated. Thanks! UPDATE: The data set will be changed dynamically. Web service will have a separate method to add IP or IP range and on top of that there will be a scheduled task that will trigger data cleanup every 10-15 minutes according to some rules. UPDATE 2: a separate benchmark project will be kicked up that should use MSSQL as a data backend (instead on in-memory list).

  • UIWebView not loading URL

    - by jerincbus
    I'm having trouble getting a UIWebView to load a URL that I'm sending to it. Before I get into my code I was wondering if URL has to start with "http://" or can it start with "www."? I'm using an IBAction to push a UIView on to the stack: (IBAction)goToWebView { WebViewController *webController = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:[NSBundle mainBundle]]; //set the strings webController.webTitle = [self Title]; webController.webURL = [self website]; //Push the new view on the stack [[self navigationController] pushViewController:webController animated:YES]; [webController release]; webController = nil; } Then here is my WebViewController.h file: @interface WebViewController : UIViewController { IBOutlet UIWebView *webView; NSString *webTitle; NSString *webURL; } @property (nonatomic, retain) IBOutlet UIWebView *webView; @property (nonatomic, retain) NSString *webTitle; @property (nonatomic, retain) NSString *webURL; here And my WebViewController.m file: - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = webURL; //Create a URL object. NSURL *url = [NSURL URLWithString:urlAddress]; //URL Requst Object NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; //Load the request in the UIWebView. [webView loadRequest:requestObj]; }

  • JQuery ajax request returns error and status 0

    - by Kucebe
    I use this pseudo-class to make ajax request to server: function RequestManager(url, params, success, error){ //save this ajax configuration this._ajaxCall = null; this._url= url; this._type = params.type; this._timer = params.timer || 0; this._success = function(){ alert("ok"); }; this._error = function(){ alert("ko"); }; } RequestManager.prototype = { require : function(tag){//here there will be a tag object in array format if(this.timer>0){ //wait this.timer } if(this.ajaxCall != null ){ this.ajaxCall.abort(); this.ajaxCall = null; } var self = this; this.ajaxCall = $.ajax({ url: this._url, type: this._type, data: tag, success: function(xmlResponse){ var responseArray = []; var response = _extractElements(xmlResponse, arrayResponse); self._success(response); }, error: self._error, complete : function(xhr, statusText){ alert(xhr.status); return null; } }); } When i instantiate a new object, and i use it to load a request, it always return to me error, and status code is 0. Server correctly generates an xml document. Why i can't get a correct 200 code back?

  • Capture keystrokes (e.g., function keys) while a messagebox is up

    - by FastAl
    We have a large WinForms app, and there is a built-in bug reporting system that can be activated during testing via the F5 Key. I am capturing the F5 key with .Net's PreFilterMessage system. This works fine on the main forms, modal dialog boxes, etc. Unfortunately, the program also displays windows messageboxes when it needs to. When there is a bug with that, e.g., wrong text in the messagebox or it shouldn't be there, the messagefilter isn't executed at all when the messagebox is up! I realize I could fix it by either rewriting my own messagebox routine, or kicking off a separate thread that polls GetAsyncKeyState and calls the error reporter from there. However I was hoping for a method that was less of a hack. Here's code that manifests the problem: Public Class Form1 Implements IMessageFilter Private Sub Form1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click MsgBox("now, a messagebox is up!") End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Application.AddMessageFilter(Me) End Sub Public Function PreFilterMessage(ByRef m As System.Windows.Forms.Message) _ As Boolean Implements IMessageFilter.PreFilterMessage Const VK_F5 As Int32 = &H74 Const WM_KEYDOWN As Integer = &H100 If m.Msg = WM_KEYDOWN And m.WParam.ToInt32 = VK_F5 Then ' In reality code here takes a screenshot, saves the program state, and shows a bug report interface ' IO.File.AppendAllText("c:\bugs.txt", InputBox("Describe the bug:")) End If End Function End Class Many thanks.

  • what's the alternative to readonlycollection when using lazy="extra"?

    - by Kunjan
    I am trying to use lazy="extra" for the child collection of Trades I have on my Client object. The trades is an Iset<Trade Trades, exposed as ReadOnlyCollection<Trade because I do not want anyone to modify the collection directly. As a result, I have added AddTrade and RemoveTrade methods. Now I have a Client Search page where I need to show the Trade Count. and on the Client details page I have a tab where I need to show all the trades for the Client in paged gridview. What I want to achieve is, for the search when I say on the client object as client.Trades.Count, nHibernate should only fire a select count(*) query. Hence I am using lazy="extra". But because I am using a ReadOnlyCollection, nHibernate fires a count query & a separate query to load the child collection trades completely. Also, I cannot include the Trades in my initial search request as this would disturb the paging because a counterparty can have n trades which would result in n rows, when I am searching clients only. So the child collections have to be loaded lazily. The second problem is that on the client details page -- Trades grid view, I have enabled paging for performance reasons. But by nature nHibernate loads the entire collection of trades as the user goes from one page to another. Ideally I want to control this by getting only trades specific to the page the user is on. How can I achieve this? I came across this very good article. http://stackoverflow.com/questions/876976/implementing-ipagedlistt-on-my-models-using-nhibernate But I am not sure if this will work for me, as lazy=extra currently doesnt work as expected with the ReadOnlyCollection. So, if I went ahead and implemented the solution this way and further enhanced it by making the List/Set Immutable, will lazy=extra give me the same problem as with ReadOnlyCollections?

  • Nant build fails - but only in TeamCity
