  • Having the output of a Console App in Visual Studio instead of the Console

    - by devoured elysium
    When doing "Console" apps in Java with Eclipse, I see the output being put in a text box on the IDE itself, instead of having a Console popping up like in Visual Studio. This comes in handy, as even after the program has exited, I can still make good use of the text that was written in it, as it doesn't get erased until I run it again. Is it possible to achieve anything like that with Visual Studio? I know that instead of doing System.Console.WriteLine(str); I can do System.Diagnostics.Debug.WriteLine(str); but it is not quite the same thing, as you get a lot of "junk" in the Output window, as all the loaded symbols and such. Even better, is it possible to have everything done in the IDE itself, when you run your app, instead of having the Console running? Thanks

  • In html 5, how to positioning a div element on top of a canvas element?

    - by Unraised
    Hi. Can anyone help me: I'm trying to put a div (say, 10px by 10px) element on top (in front) of a canvas element (say 500px by 500px) in html. I have tried changing the z-index of each, to no avail. Does anybody have any ideas, or is it one of those things that you can't really do? I already know how to do absolute positioning and everything, the div element just hangs out in the background behind the canvas element. I need a way to bring it to the front and the canvas element to the back. Thanks!

  • ASP.NET MVC 1: Model Binding With Disabled Textbox

    - by modernzombie
    I have a textbox that I am defining as <%= Html.TextBox("Username", Model.Form.Username, new { @class = "textbox", @disabled = "disabled" })%> In my action [AcceptVerbs(HttpVerbs.Post)] [ValidateAntiForgeryToken] public ActionResult EditLogin(LoginForm post) { ... return View(model); } post.Username will be blank, all other properties bind correctly, but if I change @disabled="disabled to @readonly="readonly" the username binds properly and everything works. It looks like model binding ignores values in disabled fields. Is their a way around this? I still need the field's value to bind to the model. I can use readonly but would prefer to use disabled so it is visually apparent to the user that they cannot edit the value of the field.

  • how to return C++ pointer in objective-C++

    - by John Smith
    I have the following objective-C++ header with the simple method to return this pointer. @interface MyObj { MyCPPObj * cpp; } -(MyCPPObj *) getObj; I have created the simple method @implementation MyObj -(MyCPPObj *) getObj { return cpp; } Everything seems to work until I actually try to use the object in another file newObj = [createdMyObj getObj]; It complains: error: cannot convert 'objc_object*' to 'MyCPPObje *' in initialization. It seems that the method is return an objective-c object, but I specifically requested a C++ pointer. How can I fix that?

  • Fiscal year handling strategies in database design

    - by Sapphire
    By fiscal year I mean all the data in the database (in all tables) that occurred in the particular year. Lets say that we are building an application that allows user to choose from different years. What way of implementing this would you prefer, and why: Separate fiscal year data based on multiple separate database instances (for example, on every fiscal year start you could create a new instance with no data) Have everything in one database, but with logic that automatically separates records from different years. Personally, I have "seen" both methods, and I would choose the second. The only argument I can think of for the first method is to have less records in case that these are really big databases - but still, you could "archive" old records by joining them in summaries or by some other way. What do you think?

  • How to print WPF Grid paged?

    - by Oliver Hanappi
    Hi! I'm printing a WPF grid. As long as the data fits on one page, everything works fine. But sometimes the grid contains more data. Therefore I need to split the grid into multiple pages. Can anybody help me? My code looks like this (visual is the grid). var printCapabilities = printDialog.PrintQueue.GetPrintCapabilities(printDialog.PrintTicket); var size = new Size(printCapabilities.PageImageableArea.ExtentWidth, printCapabilities.PageImageableArea.ExtentHeight); visual.Measure(size); visual.Arrange(new Rect(new Point(printCapabilities.PageImageableArea.OriginWidth, printCapabilities.PageImageableArea.OriginHeight), size)); printDialog.PrintVisual(visual, "Print ListView"); Should I try another control? I've tried WPF Toolkit DataGrid, but I couldn't manage to get it printed. I've heard something of a flow document, can this help me? Best Regards Oliver Hanappi

  • WPF MVVM: TextBox and default Button binding does update too late

    - by Sam
    I've got a simple WPF dialog with these two controls: <TextBox Text="{Binding MyText}"/> <Button Command="{Binding MyCommand}" IsDefault="True"/> Now, when I enter some text in the TextBox and click the button using the mouse, everything works like expected: the TextBox will set MyText and MyCommand is called. But when I enter some text and hit enter to "click" the default button, it does not work. Since on hitting enter the focus does not leave the TextBox, the binding will not be refresh MyText. So when MyCommand is called (which works), MyText will contain old data. How do I fix this in MVVM? In classic code-behind I probably just would call "MyButton.Focus()" in the MyCommand handler, but in MVVM the MyCommand handler does know nothing about the button. So what now`?

  • Performance implications of Synchronous Sockets vs Asynchronous Sockets

    - by Akash Kava
    We are trying to build an SMTP Server to receive mail notifications from various clients over internet. As each of the communication will be longer and it needs to log everything, doing this Asynchronous way is little challenging as well as by using Socket's Asynchronous methods we are not sure of how flow of control and error handling happens. Previously we wrote lot of server/client apps but we always used Synchronous sockets, reason being they are longer sessions and each session also has lot of local data to manage and parsing messages etc. Does anyone have any experience over real performance differences between these two methods? Async calls use ThreadPool which we have experienced many times to just die for no reason. And we fail to restart threadpool etc. In one way Request-Response protocol of HTTP, Async Sockets makes sense, but SMTP/IMAP etc protocols are longer and they have interleaved messages plus state machine of server. So Async methods are really complicated to program. However if anyone can share the performance of Sockets, it will be helpful.

  • QuickReport throws "There Is No Default Printer Currently Selected" Exception

    - by M Schenkel
    I have created a Delphi Service which prints TQuickReports. Everything works fine if compiled and run as a Windows Application. But when converted to operate as a service trying to create a form containing a TQuickRep component throws the exception. This service runs fine on many other boxes but not this one in particular. Here are some details: Using QuickReport version 4.07 Box is a Windows Server 2008 operating system. Using Delphi 2007 Printer.Printers.Count is returning a positive value. In fact I can list out all of the printers. I have tried running the service both using Local System Account and Logged on as an Admin.

  • SharePoint 2010 FBA with custom form - 403 error

    - by Chris R Chapman
    I have a SharePoint 2010 site that is configured for Forms Based Auth using custom role, membership and profile providers. This works perfectly using the OOTB SharePoint 2010 FBA form (ie. under /_forms in the web app virtual directory). My problem is with a custom login form that is located in a separate folder, /Landing/Login/default.aspx. I've configured the web app to point to this form (contains an unmodified ASP.NET login control), which is rendered when the user hits the root URL. The problem comes when they submit their credentials and the form posts back for the redirection to /_layouts/Authenticate.aspx. It stops cold with a 403. If I revert back to the OOTB FBA form (using the same providers) everything works fine. Any suggestions on what could be going wrong?

  • How to build 64-bit Python on OS X 10.6 -- ONLY 64 bit, no Universal nonsense

    - by ssteiner
    I just want to build this on my development machine -- the binary install from Python.org is still 32 bits and installing extensions (MySQLdb, for example) is driving me nuts with trying to figure out the proper flags for each and every extension. Clarification: I did NOT replace the system Python, I just installed the Python.org binary into its normal place at /Library/..., not /System/Library/.... Everything else seems to build 64 bit by default, and the default Python 2.6.1 was 64 bit (before I replaced it with the Python.org build figuring it was a direct replacement)` I just want a 64 bit only build that will run on my one machine without any cruft. Does anyone have a simple answer? Thanks much, [email protected]

  • Value of AppDomain.CurrentDomain.SetupInformation.ConfigurationFile changes based on if the file exi

    - by Dan Neely
    I have a check to make sure the app.config file exists and to report an error if it does not: System.Windows.Forms.MessageBox.Show(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile); if (!File.Exists(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile)) { throw new ConfigurationErrorsException("Unable to find configuration file. File is expected at location: " + AppDomain.CurrentDomain.SetupInformation.ConfigurationFile + "\n"); } When I build the app.config file in my solution is added to the output directory as AppName.exe.config, and if run from outside visual studio AppDomain.CurrentDomain.SetupInformation.ConfigurationFile contains the path C:...\AppName.exe.config (from within VS it's C:..\AppName.vshost.exe.config). If I delete AppName.exe.config, the value is C:..\Appname.config (no .exe). I did a bit of farther experimentation, and if Appname.config exists that file will also work to load my setting values. What's going on here? I need to have everything consistent for error reporting purposes.

  • I have string with "\u00a0" and I need to replace it with "" str_replace fails

    - by 0plus1
    I need to clean a string that comes (copy/pasted) from various office suite (excel, access, word) each with his own set of encoding. I'm using json_encode for debugging purposes in order to being able to see every single encoded character. I'm able to clean everything I found so far (\r \n) with str_replace, but with \u00a0 I have no luck. $string = '[email protected]\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0;[email protected]'; //this is the output from json_encode $clean = str_replace("\u00a0", "",$string); returns: [email protected]\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0;[email protected] that is exactly the same, it completly ignores \u00a0. Is there a way around this also I'm feeling I'm reinventing the wheel, is there any function/class that completely strips EVERY possibile char of EVERY possible encoding? Thank you for your time. _EDIT_ After the first two replies I need to clarify that my example DOES work because it's the output from json_encode not the actual string! _EDIT_

  • access violation in wglMakeCurrent

    - by Stefan
    Sometimes in my OpenGL application I get an access violation in the following API call: wglMakeCurrent(NULL, NULL); The application only has one single thread, and I've checked that before that call, both the DC and HGLRC that are currently used are correct and valid. There are three different windows with OpenGL content, and they're all redrawn on WM_PAINT messages and if a refresh is required due to user interaction (e.g., picking an object). Also this access violation happens on different machines with different graphic cards, so I don't think it's a driver issue. What could make this API call crash? What should I investigate in the app code to find out where/why this happens? I'm really lost here since I've checked everything I could think of already. I hope someone can give me hints/ideas on what more to check.

  • Validating ModelChoiceField in Django forms

    - by Andrey
    I'm trying to validate a form containing a ModelChoiceField: state = forms.ModelChoiceField(queryset=State.objects.all(), empty_label=None) When it is used in normal circumstances, everything goes just fine. But I'd like to protect the form from the invalid input. It's pretty obvious that I must get forms.ValidationError when I put invalid value in this field, isn't it? But if I try to submit a form with a value 'invalid' in 'state' field, I get ValueError: invalid literal for int() with base 10: 'invalid' and not the expected forms.ValidationError. What should I do? I tried to place a def clean_state(self) to check this field but that didn't work plus I don't think this is a good solution, there must be something more simple but I just missed that.

  • iPhone SDK 3.2 and UIAppFonts

    - by tarmo
    I've added my custom font to UIAppFonts and it's loaded just fine: (shows up in [UIFont familyNames] ). When I manually set the font in viewDidLoad { [myLabel setFont: [UIFont fontWithName:@"CustomFont" size: 65.0]]; } everything works and the font is rendered. However doing the same thing in IB doesn't (some other default font is used instead). Having to create IBOutlets for each label and fixing up the fonts manually in viewDidLoad is pretty painful. Anyone else had problems getting the custom font support to work with 3.2 SDK and IB?

  • Why does NUnit ignore datapoints when using generics in a theory

    - by The Chairman
    I'm trying to make use of the TheoryAttribute, introduced in NUnit 2.5. Everything works fine as long as the arguments are of a defined type: [Datapoint] public double[,] Array2X2 = new double[,] { { 1, 0 }, { 0, 1 } }; [Theory] public void TestForArbitraryArray(double[,] array) { // ... } It does not work, when I use generics: [Datapoint] public double[,] Array2X2 = new double[,] { { 1, 0 }, { 0, 1 } }; [Theory] public void TestForArbitraryArray<T>(T[,] array) { // ... } NUnit gives a warning saying No arguments were provided. Why is that?

  • HttpAddUrl permissions

    - by Ghostrider
    I'm trying to run a custom WinHTTP based web-server on Windows Server 2008 machine. I pass "http://*:22222/" to HttpAddUrl When I start my executable as Administrator or LocalSystem everything works fine. However if I try to run it as NetworkService to minimize security risks (since there are no legitimate reasons for the app to use admin rights) function fails with "Access Denied" error code. I wasn't aware of NetworkService having any restrictions on which ports and interfaces it can listen on. Is there a way to configure permissions in such a way so that I actually can run the app under NetworkService account and connect to it from other internet hosts?

  • How to rollback in EF4?

    - by Jaxidian
    In my research about rolling back transactions in EF4, it seems everybody refers to this blog post or offers a similar explanation. In my scenario, I'm wanting to do this in a unit testing scenario where I want to rollback practically everything I do within my unit testing context to keep from updating the data in the database (yeah, we'll increment counters but that's okay). In order to do this, is it best to follow the following plan? Am I missing some concept or anything else major with this (aside from my SetupMyTest and PerformMyTest functions won't really exist that way)? using (var ts = new TransactionScope()) { // Arrange SetupMyTest(context); // Act PerformMyTest(context); var numberOfChanges = context.SaveChanges(false); // if there's an issue, chances are that an exception has been thrown by now. // Assert Assert.IsTrue(numberOfChanges > 0, "Failed to _____"); // transaction will rollback because we do not ever call Complete on it }
