  • WinForms - DateTimePicker default month selection behavior for Server 2003 vs Server 2008?

    - by Mike Loux
    Good Afternoon! Has anybody else noticed a change in the default behavior of the "next" and "previous" month arrows in the standard WinForms DateTimePicker control? I have users running on both Windows Server 2003 and Windows Server 2008 R2, and they are reporting that on 2008 (and Vista/Win7), clicking the right or left arrows on the drop-down Calendar now selects the first day of the month rather than retaining the same day like 2003 (and XP) does. I have checked this out (I have a Win7 machine) and I have confirmed this behavior. I would prefer that the behavior remain consistent whenever possible. Does anybody know what causes this and if there is a way to get around this? Is there a way to trap the arrow-click event and force the resulting date to retain the original day rather than be reset to the first of the month? I thought about seeing if there was a way to hit-test the control on a MouseUp event and determine if the arrow buttons were clicked, and then override the month value being set, but I'm not sure if that is even possible. Can anybody provide some wisdom or insight? Thanks!

  • How to learn using Hadoop

    - by ajay
    hi, I want to learn hadoop. However, I don't have access to a cluster now. Is it possible for me to learn it and use it for writing programs and learn it properly. Would it be helpful to run multiple linux VMs and then use them as boxes to run hadoop? Or you think that is more of a stretch and running it on a multiple hosts is the same as running in on single host (in terms of setup, Hadoop API used, the architecture of the map-reduce programs etc) Thanks,

  • ExtJS data store for tree

    - by drewda
    I've got a basic ExtJS question, which I can't seem to resolve based on reading the docs and searching. Currently I have a TreePanel that loads JSON directly from a URL. I'm trying to separate the data from the view, so that I can also use that data to feed into an OpenLayers map (using GeoExt). How can I point a TreePanel to an Ext.data.Store rather than to a URL?

  • how to update UI controls in cocoa application from background thread

    - by AmitSri
    following is .m code: #import "ThreadLabAppDelegate.h" @interface ThreadLabAppDelegate() - (void)processStart; - (void)processCompleted; @end @implementation ThreadLabAppDelegate @synthesize isProcessStarted; - (void)awakeFromNib { //Set levelindicator's maximum value [levelIndicator setMaxValue:1000]; } - (void)dealloc { //Never called while debugging ???? [super dealloc]; } - (IBAction)startProcess:(id)sender { //Set process flag to true self.isProcessStarted=YES; //Start Animation [spinIndicator startAnimation:nil]; //perform selector in background thread [self performSelectorInBackground:@selector(processStart) withObject:nil]; } - (IBAction)stopProcess:(id)sender { //Stop Animation [spinIndicator stopAnimation:nil]; //set process flag to false self.isProcessStarted=NO; } - (void)processStart { int counter = 0; while (counter != 1000) { NSLog(@"Counter : %d",counter); //Sleep background thread to reduce CPU usage [NSThread sleepForTimeInterval:0.01]; //set the level indicator value to showing progress [levelIndicator setIntValue:counter]; //increment counter counter++; } //Notify main thread for process completed [self performSelectorOnMainThread:@selector(processCompleted) withObject:nil waitUntilDone:NO]; } - (void)processCompleted { //Stop Animation [spinIndicator stopAnimation:nil]; //set process flag to false self.isProcessStarted=NO; } @end I need to clear following things as per the above code. How to interrupt/cancel processStart while loop from UI control? I also need to show the counter value in main UI, which i suppose to do with performSelectorOnMainThread and passing argument. Just want to know, is there anyother way to do that? When my app started it is showing 1 thread in Activity Monitor, but when i started the processStart() in background thread its creating two new thread,which makes the total 3 thread until or unless loop get finished.After completing the loop i can see 2 threads. So, my understanding is that, 2 thread created when i called performSelectorInBackground, but what about the thrid thread, from where it got created? What if thread counts get increases on every call of selector.How to control that or my implementation is bad for such kind of requirements? Thanks

  • How to create javascript object from form elements using jQuery

    - by ob
    I'd like to be able to create a javascript object from my html form and am wondering if there's a good way to do this using jquery. I guess what i'm looking for is something similar to $.serialize, but which would result in a map instead of a string. <form> <input type="text" name="foo1" value="bar1" /> <input type="text" name="foo2" value="bar2" /> </form> desired result: { foo1:"bar1", foo2:"bar2" }

  • DotNetNuke and Subversion guidelines

    - by David Stratton
    I've Googled, Binged, and here at StackOverflow, looked through the related questions and searched, but I'm not finding what I'm looking for. I've also searched documentation on DNN. What I'm looking for is any guidance (tutorials, blogs, step-by-step instructions for setting up a repository) etc from people who are experienced in using DotNetNuke with SVN. We use SVN for all our source control, and have no problem with standard applications, because we pretty much built the repository and directory structure to work with our processes. This means when we do web sites, in Visual Studio, we do file based web sites, rather than setting them up in the local IIS. It just makes things easier for us. However, with DNN, it appears that even if you get the source code, it is expecting to be set up in the local IIS, which means additional headaches for us. For example, we are moving all of our source code off our local C drives, and onto a shared drive on a server. This is to enable backups in addition to our normal source control. (This was a management decision). So that means that we need to change the virtual web app when we make the move. Has anyone come up with a good way to work around this? Can DNN be set up so that the developer web server in Visual Studio can be used, so that we can treat it just like any normal web app? Am I missing something obvious? Edit - added I'm willing to accept answers like "We tried it and never got it to work", and "It can't be done" as answers. I'm always open to hearing "It can't be done the way you want. You need to change your procedures to match how it works" if necessary. I guess if you've got experience trying this and just couldn't get it to work, I can learn from your experience that way as well, but some detail would be good.

  • Hibernate and default values

    - by Schildmeijer
    Is it possible to use annotations to map a default value for a column? eg. I have a column named 'date' which is supposed to be '0000-00-00 00:00:00' if not date is explicitly given. I know I can add this to the ctor of the Entity. But then the default behavior will no be present in my database backend. (eg. Default column in mysql)

  • Disposing ActiveX resources owned by another thread

    - by Stefan Teitge
    I've got a problem problem with threading and disposing resources. I've got a C# Windows Forms application which runs expensive operation in a thread. This thread instantiates an ActiveX control (AxControl). This control must be disposed as it uses a high amount of memory. So I implemented a Dispose() method and even a destructor. After the thread ends the destructor is called. This is sadly called by the UI thread. So invoking activexControl.Dispose(); fails with the message "COM object that has been separated from its underlying RCW", as the object belongs to another thread. How to do this correctly or is it just a bad design I use? (I stripped the code down to the minimum including removing any safety concerns.) class Program { [STAThread] static void Main() { // do stuff here, e.g. open a form new Thread(new ThreadStart(RunStuff); // do more stuff } private void RunStuff() { DoStuff stuff = new DoStuff(); stuff.PerformStuff(); } } class DoStuff : IDisposable { private AxControl activexControl; DoStuff() { activexControl = new AxControl(); activexControl.CreateControl(); // force instance } ~DoStuff() { Dispose(); } public void Dispose() { activexControl.Dispose(); } public void PerformStuff() { // invent perpetuum mobile here, takes time } }

  • jquery buttons icons for dialog

    - by khinester
    I have this code: $(function() { var mainButtons = [ {text: "Invite" , 'class': 'invite-button' , click: function() { // get list of members alert('Invite was clicked...'); } } // end Invite button , {text: "Options" , 'class': 'options-button' , click: function() { alert('Options...'); } } // end Options button ] // end mainButtons , commentButtons = [ {text: "Clear" , 'class': 'clear-button' , click: function() { $('#comment').val('').focus().select(); } } // end Clear button , {text: "Post comment" , 'class': 'post-comment-button' , click: function() { alert('send comment...'); } } // end Post comment ] // end commentButtons $( "#form" ).dialog({ autoOpen: false , height: 465 , width: 700 , modal: true , position: ['center', 35] , buttons: mainButtons }); $( "#user-form" ) .button() .click(function() { $(this).effect("transfer",{ to: $("#form") }, 1500); $( "#form" ).dialog( "open" ); $( ".invite-button" ).button({ icons: {primary:'ui-icon-person',secondary:'ui-icon-triangle-1-s'} }); $( ".options-button" ).button({ icons: {primary:'ui-icon-gear'} }); }); // Add comment... $("#comment, .comment").click(function(){ $('#comment').focus().select(); $("#form").dialog({buttons: commentButtons}); $( ".post-comment-button" ).button({ icons: {primary:'ui-icon-comment'} }); $( ".clear-button" ).button({ icons: {primary:'ui-icon-refresh'} }); }); //Add comment // Bind back the Invite, Options buttons $(".files, .email, .event, .map").click(function(){ $("#form").dialog({buttons: mainButtons}); $( ".invite-button" ).button({ icons: {primary:'ui-icon-person',secondary:'ui-icon-triangle-1-s'} }); $( ".options-button" ).button({ icons: {primary:'ui-icon-gear'} }); }); // Tabs $( "#tabs" ).tabs(); $( ".tabs-bottom .ui-tabs-nav, .ui-tabs-nav > *" ) .removeClass( "ui-widget-header" ) .addClass( "ui-corner-bottom" ); }); ? What is the right way to add the button icons? As in my code I had to add it two times, once: $( "#user-form" ) .button() .click(function() { $(this).effect("transfer",{ to: $("#form") }, 1500); $( "#form" ).dialog( "open" ); ... and $(".files, .email, .event, .map").click(function(){ ... Could this code be improved further? I don't seem to be able to get the "transfer" effect to work correctly in a modal. I added: , close: function() { $(this).effect("transfer",{ to: $("#user-form") }, 1500); } to the $( "#form" ).dialog({ How would you go about in getting the "transfer" to work nicely when you open and close the dialog box?

  • Where to store application global variable?

    - by Shawn Mclean
    I'm using silverlight, project structure is similiar to any other .net app. I have a map control that I would like to store what mode it is in (either road or aerial) so that other controls can access this. Where do I put this enum variable, I plan to use 2 way binding on it so both are updated when either changes. Thanks.

  • How to best launch C++ application from web page

    - by JB
    I guess there are two parts to this question, one technical and one best practice for security and doing things "right". I'm working on a little game using C++ / directx but I would like to be able to launch it from a web page by someone clicking on a link on that page. Ideally I would like the first time they clicked for it to launch an installer downloads and installs the game on their machine, and then the next time to launch an application which updates the game from a web site if it's old and then launches it. I have no problems with the expected security popups and questions the first time it runs. I want people to be certain what they are installing and understand what they are doing. But it would be nice if once it is installed they could run it with the minimum of fuss. My question then is what technologies I could use to do this? I'm thinking that it would need a browser plugin and an activex control so that first time you'd install that, and subsequently the control/plugin would be able to launch the game. I'm not sure that under newer browser secuity models that a plugin would have the permissions to be able to run an installer though or silently invoke applications on the client machine even if they are already installed. Is there a more sensible way to achive what I want to achieve? And I'm worried about the security aspects too. I want this to be convenient for users but I of course want to do it "right". I know this can be done as I've seen several mmorpg type games that launch in this way from the browser now but it's not entirely clear to me how they've done it.

  • K-means algorithm variation with minimum measure of size

    - by user1464628
    I'm looking for some algorithm such as k-means for grouping points on a map into a fixed number of groups, by distance. The number of groups has already been decided, but the trick part (at least for me) is to meet the criteria that the sum of MOS of each group should in the certain range, say bigger than 1. Is there any way to make that happen? ID MOS X Y 1 0.47 39.27846 -76.77101 2 0.43 39.22704 -76.70272 3 1.48 39.24719 -76.68485 4 0.15 39.25172 -76.69729 5 0.09 39.24341 -76.69884

  • how to create static line in coreplot

    - by Rémi Bédard-Couture
    I am trying to make my control lines static so instead of being displayed as part of the graph(the control lines are moving with the graph), they would be displayed like an axis the app can only scroll horizontally i'm talking about the two red line and the green line(which i put over the x axis) this is how i do my lines: // Center line CPTScatterPlot *centerLinePlot = [[CPTScatterPlot alloc] init]; centerLinePlot.identifier = kCenterLine; CPTMutableLineStyle *lineStyle = [CPTMutableLineStyle lineStyle]; lineStyle.lineWidth = 2.0; lineStyle.lineColor = [CPTColor greenColor]; centerLinePlot.dataLineStyle = lineStyle; centerLinePlot.dataSource = self; [graph addPlot:centerLinePlot]; but maybe it has something to do with the displayed range: ////////ajuste la portion a voir if(data.Resultats.count>10) { plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(data.Resultats.count - 10) length:CPTDecimalFromDouble(10)]; } plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(RangeMin) length:CPTDecimalFromDouble(RangeMax-RangeMin)]; // Adjust visible ranges so plot symbols along the edges are not clipped CPTMutablePlotRange *xRange = [plotSpace.xRange mutableCopy]; CPTMutablePlotRange *yRange = [plotSpace.yRange mutableCopy]; //place l'axe x sur la ligne de controle pour voir les WorkOrders x.orthogonalCoordinateDecimal = CPTDecimalFromDouble(center); //x.orthogonalCoordinateDecimal = yRange.location; //y.orthogonalCoordinateDecimal = xRange.location; //x.visibleRange = xRange; //y.visibleRange = yRange; //x.gridLinesRange = yRange; //y.gridLinesRange = xRange; [xRange expandRangeByFactor:CPTDecimalFromDouble(1.15)];//1.05 [yRange expandRangeByFactor:CPTDecimalFromDouble(1.15)]; plotSpace.xRange = xRange; plotSpace.yRange = yRange;

  • Ideas on implementing threads and cross process communication. - C

    - by Jamie Keeling
    Hello all! I have an application consisting of two windows, one communicates to the other and sends it a struct constaining two integers (In this case two rolls of a dice). I will be using events for the following circumstances: Process a sends data to process b, process b displays data Process a closes, in turn closing process b Process b closes a, in turn closing process a I have noticed that if the second process is constantly waiting for the first process to send data then the program will be just sat waiting, which is where the idea of implementing threads on each process occured. I have already implemented a thread on the first process which currently creates the data to send to the second process and makes it available to the second process. The problem i'm having is that I don't exactly have a lot of experience with threads and events so I'm not sure of the best way to actually implement what I want to do. Following is a small snippet of what I have so far in the producer application; Rolling the dice and sending the data: case IDM_FILE_ROLLDICE: { hDiceRoll = CreateThread( NULL, // lpThreadAttributes (default) 0, // dwStackSize (default) ThreadFunc(hMainWindow), // lpStartAddress NULL, // lpParameter 0, // dwCreationFlags &hDiceID // lpThreadId (returned by function) ); } break; The data being sent to the other process: DWORD WINAPI ThreadFunc(LPVOID passedHandle) { HANDLE hMainHandle = *((HANDLE*)passedHandle); WCHAR buffer[256]; LPCTSTR pBuf; LPVOID lpMsgBuf; LPVOID lpDisplayBuf; struct diceData storage; HANDLE hMapFile; DWORD dw; //Roll dice and store results in variable storage = RollDice(); hMapFile = CreateFileMapping( (HANDLE)0xFFFFFFFF, // use paging file NULL, // default security PAGE_READWRITE, // read/write access 0, // maximum object size (high-order DWORD) BUF_SIZE, // maximum object size (low-order DWORD) szName); // name of mapping object if (hMapFile == NULL) { dw = GetLastError(); MessageBox(hMainHandle,L"Could not create file mapping object",L"Error",MB_OK); return 1; } pBuf = (LPTSTR) MapViewOfFile(hMapFile, // handle to map object FILE_MAP_ALL_ACCESS, // read/write permission 0, 0, BUF_SIZE); if (pBuf == NULL) { MessageBox(hMainHandle,L"Could not map view of file",L"Error",MB_OK); CloseHandle(hMapFile); return 1; } CopyMemory((PVOID)pBuf, &storage, (_tcslen(szMsg) * sizeof(TCHAR))); //_getch(); MessageBox(hMainHandle,L"Completed!",L"Success",MB_OK); UnmapViewOfFile(pBuf); return 0; } I'd like to think I am at least on the right lines, although for some reason when the application finishes creating the thread it hits the return DefWindowProc(hMainWindow, message, wParam, lParam); it crashes saying there's no more source code for the current location. I know there are certain ways to implement things but as I've mentioned I'm not sure if i'm doing this the right way, has anybody else tried to do the same thing? Thanks!
