• Selecting items from events, as evenly spaced as possible

  - by Matt Warren

  If I have an event that happens 15 times a second (numbered 1 - 15), but I only want to process it 3 times I can choose [1], [6] and [11],. It's important that the events I process are as evenly spaced as possible and take into account wrap-around, i.e. the events are continuous 13, 14, 15, 1, 2, 3 etc. If I want 4 items the best I can do is [1], [5], [9] & [13]. Is there a general algorithm that will calculate which events I need to process given the total number of events (total) and the number to process (processAmount).

• Why should I use an N-Tier Approach When using an SqlDatasource is ALOT EASIER ?

  - by The_AlienCoder

  When it comes to web development I have always tried to work SMART not HARD. So for along time My Aproach to interacting with databases in my AspNet projects has been this : 1) Create my stored procedures 2) Drag an SQLDatasource control on my aspx page 3) Bind a DataList Control to my SQLDatasource 4) Insert, Update & Delete by using my Datalist or programmatically using built in SQLDatasource methods e.g MySqlDataSource.InsertParameters["author"].DefaultValue = TextBox1.Text; MySqlDataSource.Insert(); Recently however I got a relatively easy web project. So I decided to employ a 3-tier Model...But I got exhausted halfway and just didnt seem worth it ! It seemed like I was working too HARD for a project that could have been easily accomplished by a couple of SqlDataSource Controls. So Why Is the N-Tier Model better than my Approach? Has it anything to do with performance? What are the advantages of the ObjectDataSource control over the SqlDataSource Control?

• Detecting a message box opened in another application

  - by richie

  I am developing a windows service, in vb .et, that launches a legacy application that performs some work. The service acts as a wrapper around the legacy app allowing users to automate an otherwise manual operation. Everything is working great, except occasionally the legacy app displays a messagebox. When it does this the process halts until the message box is closed. As the service will be running on a server there will be no user to close the message box. The service launches the legacy application in a System.Diagnostics.Process. My question is, is there way to detect that a message box has been displayed by a process that I have started using System.Diagnostics.Process and is there a way to through code to close the messagebox. I've tried to be brief so if you need more information please let me know. Thanks in advance Richie

• C++/CLI : Interop window is not properly configured

  - by raytaller

  Hi, I'm trying to load a WPF control in a C++/CLI application, using the HwndSource class. Here is my code : UBOOL MyWindowWrapper::Init(const HWND InParentWindowHandle) { Interop::HwndSourceParameters sourceParams( "WindowName" ); sourceParams.PositionX = 0; sourceParams.PositionY = 0; sourceParams.ParentWindow = (IntPtr)InParentWindowHandle; sourceParams.WindowStyle = (WS_VISIBLE | WS_CHILD); sourceParams.HwndSourceHook = nullptr; InteropWindow = gcnew Interop::HwndSource(sourceParams); Control = gcnew MyWPFUserControl(); InteropWindow-RootVisual = Control; InteropWindow-AddHook( gcnew Interop::HwndSourceHook( this, &MyWindowWrapper::MessageHookFunction ) ); return TRUE; } And I define a Hook function so the keyboard events are passed to the window : IntPtr MyWindowWrapper::MessageHookFunction( IntPtr HWnd, int Msg, IntPtr WParam, IntPtr LParam, bool% OutHandled ) { IntPtr Result = (IntPtr)0; OutHandled = false; if( Msg == WM_GETDLGCODE ) { OutHandled = true; // This tells Windows that we'll need keyboard events for this control Result = IntPtr( DLGC_WANTALLKEYS | DLGC_WANTCHARS | DLGC_WANTMESSAGE ); } return Result; } And here are my problems : The window title is empty (so the "WindowName" parameter is not taken in account) Only some keyboard events are transferred : space, control, arrows are ok, but I can't type any character in all the text boxes What am I doing wrong ? Thanks !

• Pattern or recommneded refactoring for method

  - by iKode

  I've written a method that looks like this: public TimeSlotList processTimeSlots (DateTime startDT, DateTime endDT, string bookingType, IList<Booking> normalBookings, GCalBookings GCalBookings, List<DateTime> otherApiBookings) { { ..... common process code ...... while (utcTimeSlotStart < endDT) { if (bookingType == "x") { //process normal bookings using IList<Booking> normalBookings } else if (bookingType == "y") { //process google call bookings using GCalBookings GCalBookings } else if (bookingType == "z" { //process other apibookings using List<DateTime> otherApiBookings } } } So I'm calling this from 3 different places, each time passing a different booking type, and each case passing the bookings I'm interested in processing, as well as 2 empty objects that aren't used for this booking type. I'm not able to get bookings all into the same datatype, which would make this easier and each booking type needs to be processed differently, so I'm not sure how I can improve this. Any ideas?

• A question about making a C# class persistent during a file load

  - by Adam

  Apologies for the indescriptive title, however it's the best I could think of for the moment. Basically, I've written a singleton class that loads files into a database. These files are typically large, and take hours to process. What I am looking for is to make a method where I can have this class running, and be able to call methods from within it, even if it's calling class is shut down. The singleton class is simple. It starts a thread that loads the file into the database, while having methods to report on the current status. In a nutshell it's al little like this: public sealed class BulkFileLoader { static BulkFileLoader instance = null; int currentCount = 0; BulkFileLoader() public static BulkFileLoader Instance { // Instanciate the instance class if necessary, and return it } public void Go() { // kick of 'ProcessFile' thread } public void GetCurrentCount() { return currentCount; } private void ProcessFile() { while (more rows in the import file) { // insert the row into the database currentCount++; } } } The idea is that you can get an instance of BulkFileLoader to execute, which will process a file to load, while at any time you can get realtime updates on the number of rows its done so far using the GetCurrentCount() method. This works fine, except the calling class needs to stay open the whole time for the processing to continue. As soon as I stop the calling class, the BulkFileLoader instance is removed, and it stops processing the file. What I am after is a solution where it will continue to run independently, regardless of what happens to the calling class. I then tried another approach. I created a simple console application that kicks off the BulkFileLoader, and then wrapped it around as a process. This fixes one problem, since now when I kick off the process, the file will continue to load even if I close the class that called the process. However, now the problem I have is that cannot get updates on the current count, since if I try and get the instance of BulkFileLoader (which, as mentioned before is a singleton), it creates a new instance, rather than returning the instance that is currently in the executing process. It would appear that singletons don't extend into the scope of other processes running on the machine. In the end, I want to be able to kick off the BulkFileLoader, and at any time be able to find out how many rows it's processed. However, that is even if I close the application I used to start it. Can anyone see a solution to my problem?

• Problem with events and ParseControl

  - by Richard Edwards

  I'm adding a control (linkbutton) dynamically using ParseControl and it's fine except when I specify an event handler. If I use: Dim c As Control = ParseControl("<asp:LinkButton id=""btnHide"" runat=""server"" text=""Hide"" OnClick="btnHide_Click" />") it correctly adds the control to the page but the click event doesn't fire. If instead I find the control in the controls collection and manually wire up the event it works fine. I've tried loading in both Page_Init and Page_Load and it's the same thing either way. Any ideas?

• How to refresh the textbox text when tabs are Changed in WPF

  - by StonedJesus

  Well in my WPF application I am using Tab Control which has around 5 tabs. The view of each tab is a user control which I add via a tool box. Main Xaml File: <Grid> <TabControl Height="Auto" HorizontalAlignment="Stretch" Margin="0" Name="tabControl1" VerticalAlignment="Stretch" Width="Auto"> <TabItem Header="Device Control" Name="Connect"> <ScrollViewer Height="Auto" Name="scrollViewer1" Width="Auto"> <my:ConnectView Name="connectView1" /> </ScrollViewer> </TabItem> <TabItem Header="I2C"> <ScrollViewer Height="Auto" Name="scrollViewer2" Width="Auto"> <my1:I2CControlView Name="i2CControlView1" /> </ScrollViewer> </TabItem> <TabItem Header="Voltage"> <ScrollViewer Height="Auto" Name="scrollViewer3" Width="Auto"> <my2:VoltageView Name="voltageView1" /> </ScrollViewer> </TabItem> </TabControl> </Grid> If you notice each view ie.e Connect, I2C and Voltage is a user control which has a view, viewmodel and model class :) Each of these views have set of textboxes in their respective xaml files. Connect.xaml: <Grid> <Textbox Text="{Binding Box}", Name="hello" /> // Some more textboxes </Grid> I2c.xaml: <Grid> <Textbox Text="{Binding I2CBox}", Name="helI2c" /> // Some more textboxes </Grid> Voltage.xaml: <Grid> <Textbox Text="{Binding VoltBox}", Name="heVoltllo" /> // Some more textboxes </Grid>** By default I have set the text of these textboxes to some value. Lets say "12" "13" "14" respectively in my view model classes. My main requirement is to set the text of these textboxes present in each user control to get refreshed when I change the tab. Description: Lets say Connect View is displayed: Value of Textbox is 12 and I edit it and change it to 16. Now I click on I2C tab and then I go back to Connect tab, I want the textbox value to get refreshed back to the initial value i.e. 12. To be precise, is their a method called visibilitychanged() which I can write in all my user control classes, where I can set the value of these Ui components whenever tabs are changed? Please help :)

• How to set a TCustomControl's Parent In Create

  - by Bill

  When we create a component as a custom control and the control is dropped on a panel the control always appears on the form rather than the containing control. How do you set the parent of the custom control in Create so that when the button is dropped on panel the buttons parent is the panel? TGlassButton = class(TCustomControl) ... public { Public declarations } constructor Create(AOwner: TComponent); override; ... constructor TGlassButton.Create(AOwner: TComponent); begin inherited; ??????????? inherited Create(AOwner); ???????????? Parent := TWinControl( AComponent ); ?????????????? ... end; The problem is designtime creation not runtime. This works perfectly: procedure TForm10.FormCreate(Sender: TObject); begin GlassButton0 := TGlassButton.Create( Panel1 ); GlassButton0.Parent := Panel1; GlassButton0.Left := 20; GlassButton0.Top := 6; GlassButton0.Width := 150; GlassButton0.Height := 25; GlassButton0.Caption := 'Created At RunTime'; end;

• Is it okay if my ViewModel 'creates' bindable user controls for my View?

  - by j0rd4n

  I have an entry-point View with a tab control. Each tab is going to have a user control embedded within it. Each embedded view inherits from the same base class and will need to be updated as a key field on the entry-point view is updated. I'm thinking the easiest way to design this page is to have the entry-point ViewModel create and expose a collection of the tabbed views so the entry-point View can just bind to the user control elements using a DataTemplate on the tab control. Is it okay for a ViewModel to instantiate and provide UI elements for its View?

• Listview Multiple Selection

  - by Evan

  Is there any way to force a listview control to treat all clicks as though they were done through the Control key? I need to replicate the functionality of using the control key (selecting an item sets and unsets its selection status) in order to allow the user to easily select multiple items at the same time. Thank you in advance.

• MPI Large Data all to all transfer

  - by csslayer

  My application of MPI has some process that generate some large data. Say we have N+1 process (one for master control, others are workers), each of worker processes generate large data, which is now simply write to normal file, named file1, file2, ..., fileN. The size of each file may be quite different. Now I need to send all fileM to rank M process to do the next job, So it's just like all to all data transfer. My problem is how should I use MPI API to send these files efficiently? I used to use windows share folder to transfer these before, but I think it's not a good idea. I have think about MPI_file and MPI_All_to_all, but these functions seems not to be so suitable for my case. Simple MPI_Send and MPI_Recv seems hard to be used because every process need to transfer large data, and I don't want to use distributed file system for now.

• using yield in C# like I would in Ruby

  - by Sarah Vessels

  Besides just using yield for iterators in Ruby, I also use it to pass control briefly back to the caller before resuming control in the called method. What I want to do in C# is similar. In a test class, I want to get a connection instance, create another variable instance that uses that connection, then pass the variable to the calling method so it can be fiddled with. I then want control to return to the called method so that the connection can be disposed. I guess I'm wanting a block/closure like in Ruby. Here's the general idea: private static MyThing getThing() { using (var connection = new Connection()) { yield return new MyThing(connection); } } [TestMethod] public void MyTest1() { // call getThing(), use yielded MyThing, control returns to getThing() // for disposal } [TestMethod] public void MyTest2() { // call getThing(), use yielded MyThing, control returns to getThing() // for disposal } ... This doesn't work in C#; ReSharper tells me that the body of getThing cannot be an iterator block because MyThing is not an iterator interface type. That's definitely true, but I don't want to iterate through some list. I'm guessing I shouldn't use yield if I'm not working with iterators. Any idea how I can achieve this block/closure thing in C# so I don't have to wrap my code in MyTest1, MyTest2, ... with the code in getThing()'s body?

• SQL Temp Tables & Replication

  - by Refracted Paladin

  I have had an issue with our replication process and would like to salvage some data. I have a process in place where I will connect to each subscriber before flagging them for reinitialization and I will run the below to pull any data they may have entered in during the "dark time". I am pretty sure this will work in a vanilla palace. What I am unsure of is whether the Global Temporary Table will persist through DB Replication. To be clear, I am not trying to Replicate the TempTable, I just want to make sure it will still exist at the local DB after the Replication so I may run the INSERT from it. Thoughts? USE MemberCenteredPlan -- Select Data from tblPLan SELECT * INTO ##MyPlan FROM tblPlan WHERE PlanID = 407869 --------------------------- -- Run Replication Process --------------------------- -- Insert Plan back into DB INSERT INTO tblPlan SELECT * FROM ##MyPlan WHERE PlanID = 407869 -- Drop Global Temp Table DROP TABLE ##MyPlan --------------------------- -- Run Replication Process ---------------------------

• Building a custom textbox in GTK

  - by CommuSoft

  I want to make my own GTK# Textbox, the textbox should draw the text and it's cursor on a special way. However keyboard and mouse-handling is quite complex and is also influenced by for instance the operating system (for instance the use of dead keys) Is there a way to build such a control without having to worry about keyboard input? I assume I have to make a textbox control that inherits the original textbox control. How can I handle drawing requests and mouse movements?

• Silverlight horizontal stretch and get position issue

  - by David

  I have a Grid (container) wich in turn has several grids(subContainers) arranged by rows. Each one of those "subContainers" has diferent columns and controls. And each of those "subContainers" has the horizontal alignment set to stretch, and it has to stay that way, since the layout this viewer depends on it. I use the "container" to set each control on it's adequate position. So far so good. Now comes my headache... I want to remove the control from the grid and put it in a canvas, at the same exact position, only, the position it returns is as if the control is set to the beggining of the grid and not it's true position. For testing purposes, I've set the "subContainters" horizontal alignment to center and (despite the layout is totally wrong) every control is in it's right position when sent to a canvas, wich it doesn't happen when HA = stretch. Here's the code I'm using to get position: GeneralTransform gt = nc.TransformToVisual(gridZoom); Point offset = gt.Transform(new Point()); So you can understand, for example, my first control should be somewhere like (80, 1090), but the point that I get is (3,3). Can anyone help me? Thanks
