• Window Size when SizeToContent is not specified

  - by moogs

  When the following XAML used, the window size is not 5000x5000, but some small window where the button is cropped. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" > <Button Width="5000" Height="5000">XXX</Button> </Window> From what I can tell, size I did not specify the SizeToContent attribute, the default is "Manual", so it will use *size of a window is determined by other properties, including Width, Height, MaxWidth, MaxHeight, MinWidth, and MinHeight. * From the WPF Windows Overview, it seems those other properties are FrameworkElement::MinHeight/Width, and FrameworkElement::MaxHeight. But since the default for the Mins are 0, the Maxs are Infinity and the Width/Height is Nan....what's going on? Where is WPF getting the window size? Any pointers to the right direction would be appreciated.

• Escape from DataContext

  - by grayscales

  I have a window that get its data from another class that is passed as DataContext. But I now also want to do data binding within the window. The window looks as follows: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <StackPanel> <TextBlock Text="{Binding UserName}" /> <TextBlock x:Name="TestTextBlock">Hello World</TextBlock> <TextBlock x:Name="TestTextBlock2" Text="{Binding ElementName=TestTextBlock,Path=Text}" /> </StackPanel> </Window> The binding between the text blocks TestTextBlock and TestTextBlock2 works fine, but only until I change the DataContext-property of the window. How can I bind between those two textblocks so that changing the DataContext will not break the data binding? Thanks in advance, Stefan

• Is it worth it to switch from home-grown remote command interface to using JMX

  - by Sam Goldberg

  Without knowing too much about JMX, I've always assumed that it would be the best approach for building in remote management to our standalone Java server application. Our server application has some minimal remote control capability, using text commands sent via TCP/IP socket to it. Using the home grown approach, it is fairly to add a new command. (Just create new command text, and the code to handle that in the message receiver). On the other hand, we have hardly implemented any commands, even though there are many things we would like to be able to execute remotely. I am trying to weigh the value of moving to incorporating JMX (learning it, and building the interfaces), versus just sticking with the home-grown approach. Does anyone have any experience or advice regarding changing an existing application to use JMX?

• Datetimepicker in windows 7

  - by maramasamy

  I am using Microsoft Date and Time Picker control(SP4) in my application.My application runs fine in xp and vista machines as date and time picker refers to mscomct2.ocx which is present in system32 for xp and vista,but for windows 7 i dont have this dll in my system .In windows we need admin rights to register that control. So is there any alternative/similar control available.......It would be helpful if you could let me know why thats not available in windows P.S : My Application is a .Net application and the reason why i have used Microsoft Date and Time Picker control(SP4) instead of .Net provided control is to display year 9999.

• What are the pro/cons of Unity3D as a choice to make games ?

  - by jokoon

  We are doing our school project with Unity3d, since they were using Shiva the previous year (which seems horrible to me), and I wanted to know your point of view for this tool. Pros: multi platform, I even heard Google is going to implement it in Chrome everything you need is here scripting languages makes it a good choice for people who are not programming gurus Cons: multiplayer ? proprietary, you are totally dependent of unity and its limit and can't extend it it's less "making a game from scratch" C++ would have been a cool thing I really think this kind of tool is interesting, but is it worth it to use at school for a project that involves more than 3 programming persons ? What do we really learn in term of programming from using this kind of tool (I'm ok with python and js, but I hate C#) ? We could have use Ogre instead, even if we were learning direct x starting january...

• College for Game Development [closed]

  - by Cole Adams

  I am currently a Freshman Computer Science Major at Samford University, but I am realizing that the actual field I want to get into is Game Development. I go to all of these classes that are supposed to make you well rounded that have nothing to do with what I want to do and frankly, after 18 years of schooling, I am sick of having to be in classes like that. I want to go to a Game Design/Development school where that is the priority and I am not overburdened with useless classes. At this point I am so tired of the Samford classes already that I am heavily considering taking next semester off and just getting a job and focusing on learning programming on my own or something like that. My question is what would be some good schools to apply to for enrollment in 2013 and what does it take to get into these schools? Thanks in advanced.

• For what types of applications is Python a bad choice?

  - by Casey Patton

  I just started learning Python, and I'd like to get some more context on the language. I realize that Python is a slow language relative to C or C++, etc. Thus, Python is probably not the best choice for applications that need to run quickly. Outside of this, it seems like Python is a great general purpose language that is easy to read and write. The available libraries give it a huge amount of functionality. Outside of performance critical applications, where is it a bad choice to use Python (and why)?

• [News] Utiliser le framework de bouchon Moq

  Moq est un framework permettant de mettre en oeuvre les mock-objets destin?es aux phases de tests. Cet excellent article illustre le principe : " (...) it is intended to be straightforward and easy to use mocking framework that doesn?t require any prior knowledge of the mocking concepts. So, it doesn't requires deep learning curve from the developers. It takes full advantage of the .NET 3.5 expression trees and the lambda expressions. Any of the methods and properties of the mock object can be easily represented in the lambda expressions."

• How do you fix the Silverlight application shift that occurs in the Firefox browser?

  - by Roy

  Hi, Currently I have an Silverlight application that when run on Firefox browser (ver 3.6) the entire contents of the Silverlight application shifts a little, and also the scrollbars on both the bottom and the side appear when I first use it. This does not happen in IE 8. How can I fix this in Firefox so it doesn't happen? The project type I created was the "Silverlight 3 Application + Website" via Expression Blend 3. This the code I am using in my MainPage.xaml: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="StackoverflowExample.MainPage" Width="640" Height="480"> <Grid x:Name="LayoutRoot" Background="Green"> <Rectangle Fill="#FFBB2020" Stroke="Black" Margin="155,58,266,178"/> <Button Margin="199,180,302,236" Content="Button"/> </Grid> </UserControl>

• Fastest bit-blit in C# ?

  - by AttackingHobo

  I know there is Unity, and XNA that both use C#, but I am don't know what else I could use. The reason I say C# is that the syntax and style is similar to AS3, which I am familiar with, and I want to choose the correct framework to start learning with. What should I use to be able to do the most possible bit-blit(direct pixel copy) objects per frame. EDIT: I should not need to add this, but I am looking for the most possible amount of objects per frame because I am making a few Bullet-Hell SHMUPS. I need thousands and thousands of bullets, particles, and hundreds of enemies on the screen at once. I am looking for a solution to do as many bit-blit operations per frame, I am not looking for a general purpose engine. EDIT2: I want bit-blitting because I do not want to exclude people who have lower end video cards but a fast processor from playing my games.

• What are some recommended video lectures for a non-CS student to prepare for the GRE CS subject test?

  - by aristos

  Well the title kinda explains all there is to explain. I'm a non-cs student and was preparing to apply PhD programs in applied mathematics. But for my senior thesis I've been reading lots of machine learning and pattern recognition literature and enjoying it a lot. I've taken lots of courses with statistics and stochastics content, which I think, would help me if I get accepted to a program with ML focus, but there are only two CS courses -introduction to programming- in my transcript and therefore I decided to take the CS subject test to increase my chances. Which courses do you think would be most essential to have a good result from CS subject test? I'm thinking of watching video lectures of them, so do you have any recommendations?

• Direct Code Support?

  - by Josh Kahane

  A few times in the past I've hit a major wall and simply couldn't progress with a certain aspect of an app as Im a beginner and still learning the ropes (Objective-C specifically). I was curious if anyone knows of any services which support programmers in real time, paid or free and will over video, audio or text chat sit and work a problem out till its fixed and look through your code? I understand Stackoverflow does a super job at this! However Im in need of something a little more tailored where someone can spend a little time to sit and look and what Im dealing with and delve into my a code if need be. Thanks.

• Sql Server SMO connection timeout not working

  - by Uros Calakovic

  I have the following PowerShell code: function Get-SmoConnection { param ([string] $serverName = "", [int] $connectionTimeout = 0) if($serverName.Length -eq 0) { $serverConnection = New-Object ` Microsoft.SqlServer.Management.Common.ServerConnection } else { $serverConnection = New-Object ` Microsoft.SqlServer.Management.Common.ServerConnection($serverName) } if($connectionTimeout -ne 0) { $serverConnection.ConnectTimeout = $connectionTimeout } try { $serverConnection.Connect() $serverConnection } catch [system.Management.Automation.MethodInvocationException] { $null } } $connection = get-smoconnection "ServerName" 2 if($connection -ne $null) { Write-Host $connection.ServerInstance Write-Host $connection.ConnectTimeout } else { Write-Host "Connection could not be established" } It seems to work, except for the part that attempts to set the SMO connection timeout. If the connection is successful, I can verify that ServerConnection.ConnectTimeout is set to 2 (seconds), but when I supply a bogus name for the SQL Server instance, it still attempts to connect to it for ~ 15 seconds (which is I believe the default timeout value). Does anyone have experience with setting SMO connection timeout? Thank you in advance.

• ASP.NET 2.0 files work in one folder, but NOT in another

  - by Steve

  I am about to leap of a building. I have created an app for a client and all the files are in a folder on their D drive. Now it is time to go production, so I copied all my files and folders to their excisting classic asp folder on the same drive. BUT NOTHING WORKS. The only difference I can see is that DEV does not require HTTPS like the production site. I also made sure all the permissions are the same on both folder. I made sure that the GAC has read rights using the aspnet_regiis tool. I am at the end of my debug knowlegde, could someone please help me out.

• Whats the thing the report bugs in php?

  - by Max Hazard

  Currently I am learning php. Php is understood by browser itself right from php sdk right? SDK include libraries right? So browser is like an interpreter of php codes. I want to know that whenever I type a wrong php syntax what is the thing report me the error? Obviously the browser is reporting the error. But what part of it? I mean I don't get it. Like writing a compiler we do lexical analysis and make the compiler which report any bug in source code. I assume here browser is analogous to compiler. I don't know exactly but compiler contains bug report functions or methods which is debugger. Debugger is part of compiler which report bugs. Does the browser contains such debuggers? Can there be any browser which doesn't understand php?

• C++/CLI: Compiling static library with /CLR support

  - by user289770

  We have old (working) code that consists of a static library compiled with /CLR, and a C++/CLI DLL that links to the static lib. We are about to add new features to this static lib. Now, I've have heard from numerous sources that CLR static libraries are not supported by Microsoft, and therefore I'm pushing to clean this up and switch to DLL before we start adding new features to this project. However, I haven't been able to find any official information from Microsoft regarding this (say, from MSDN - other than their forums). I will appreciate any resources about this whole "static lib with CLR" issue.

• Does Dart have any useful features for web programmers?

  - by marko

  http://www.dartlang.org/ I've checked out the site very briefly, and got curious. Is there any advantages of using Dart? Is it just a replacement for JavaScript? It looks like simpler Java. Writing quite a lot of C# at work, the language feels very much like what I'm used to, so learning the syntax looks like a breeze to learn. Has anybody any opinions or experiences with the language? (Compared to CoffeeScript (= I'm not doing Ruby syntax) the syntax looks more familiar to me).

• COM interop, Office 2010 x64 and Visual Studio 2010.

  - by Snake

  Hi, I just installed Offic 2010 x64 on my Windows 7 x64 laptop. It already had Visual Studio 2010 on it. Now I try to add Microsoft.Office.Interop.Excel or something to the project, but it just can't find the project. When I try to open a project from the website of Microsoft (a sample of Office development) Visual Studio says that that kind of project is not supported. How is this possible? Is it a problem that I installed x64 of Office? Or is the problem Visual Studio 2010? Thanks
