• Entity binding WPF

  - by morphsd

  I'm doing some auction sale app and I'm new to Entity Framework. I used quickest way to create and bind Wpf control and entity(wizard and drag and drop) so VS2010 generated a lot of code for me. Now I have a problem... WPF control isn't syched to my entity. I read some articles and I understood that I have to use IObservable. Is there an easy way to do that without writing that generated code manually?

• C# How do I replace an actual asterisk character (*) in a Regex expression?

  - by fraXis

  Hello, I have a statement: I have a string such as content = "* test *" I want to search and replace it with so when I am done the string contains this: content = "(*) test (*)" My code is: content = Regex.Replace(content, "*", "(*)"); But this causes an error in C# because it thinks that the * is part of the Regular Expressions Syntax. How can I modify this code so it changes all asterisks in my string to (*) instead without causing a runtime error? Thanks.

  - by haries

  I redirect the user of my application to Twitter for oauth style authentication using my app's request_token. The user is able to enter username and password on Twitter's page BUT then, instead of calling back my application, Twitter displays a page You've successfully granted access to MyAppName! Simply return to MyAppName and enter the following PIN to complete the process. 123456 Why is this happening? I have set the callback url in my app's settings. Thanks

• In MS Access form, how to color background of selected record?

  - by PowerUser

  I have a somewhat complicated looking Access Form with a continuous display (meaning multiple records are shown at once). I'd like to change the background color of the selected record only so the end-user can easily tell which record they are on. I'm thinking of perhaps a conditional format or maybe something like this: Private Sub Detail_HasFocus() Detail.BackColor(me.color)=vbBlue End Sub and something similar for when that row loses focus. This code snippet obviously won't work, but it's the kind of code I'd like to achieve.

• Determining CPU usage in WinCE

  - by Chris

  I want to be able to get the current % CPU usage in a C++ program running under Wince. I found this link that states where the source code is but I cannot find it in my platform builder installation - I expect this is because it isn't the Windows Automotive platform. Does anyone know where I can find this source code or (even better) know how I can get this information directly? i.e. what DLL / function calls to make etc.

• Rails learn's confusion

  - by Steve

  This is a beginner's rails learning confusion. When I learn rails, from time to time, I feel frustrated on rails' principle "Convention over Configuration". Rails uses heavily on conventions. A lot of them are just naming conventions. If I forget a convention, I will either use the wrong naming and get unexpected result or get things magically done but don't understand how. Sometimes, I think of configuration. At least configuration lists everything clearly and nothing is in fog. In rails, there seems a hidden, dark contract between you and the machine. If you follow the contract, you communicate well. But a beginner usually forgets items listed on the contract and this usually leads to confusion. That's why when I first pick up rails, I feel like it is somehow difficult to learn. Besides, there are many other things that could be new to a learner, such as using git, using plugins from community, using RESTful routing style, using RSpec. All these are new and come together in learning ruby and rails. This definitely adds up difficulties for a beginner. In contrast, if you learn php, it wouldn't be that bad. You can forget many things and focus on learning php itself. You don't need to learn database handling if you know SQL already(in rails, you need to learn a whole new concept migration), you don't have to learn a new decent unit test(in rails, usually they teach RSpec along the way because rails is agile and you should learn test-driven development in the early learning stage), you don't have to learn a new version control(in rails, you will be taught about git anyway), you don't have to use complicated plugins(in rails, they usually use third-party plugins in textbook examples! what the hell? why not teach how to do a simplified similar thing in rails?), you don't have to worry RESTful style. All in all, when I learn php, I learn it quick and soon I start to write things myself. Learning php is similar to learning C/java. It tastes like those traditional languages. When I learn rails, it is more difficult. And I need to learn ruby as well (I believe many of you learn ruby just because of rails). Does anyone have the similar feeling as I have? How do you overcome it and start to master rails? Hints will be welcomed. Thank you.

• Reusing a NSString variable - does it cause a memory leak?

  - by Chris S

  Coming from a .NET background I'm use to reusing string variables for storage, so is the code below likely to cause a memory leak? The code is targeting OS X on the iphone/itouch so no automatic GC. -(NSString*) stringExample { NSString *result = @"example"; result = [result stringByAppendingString:@" test"]; // where does "example" go? return result; } What confuses me is an NSStrings are immutable, but you can reuse an 'immutable' variable with no problem.
