  Hi,as stated in the subject, I want to know whether there is a control acts as a switch. Just like the one we use to open or close the light... Now I can only use two buttons. Each time only one button is enabled and when user clicks the active one, it will become disabled and the other one will be enabled...However, it is not so intuitionistic and a little bit strange...

• DavideB Wierd error : Attempted to read or write protected memory. This is often an indication that other memory is corrupt

  Ok I have a project that runs fine from the IDE, the problem is if I install the app or run it from the bin\release folder then I get this error on one of my method calls. I have tried this on a test machine and on my development machine and the results are the same. I have spent hours trying to figure this one out....... The crazy thing is, the method shows up in the stack trace but there is not code at all executed in that method. I was having the same problem when trying to instantiate a FoxPro .dll in my VS2005.net web application on the production server. My problem was in the COM .dll itself using a variable GETENV("TEMP"). The problem is that the web app was running as a user via the I ...Show All

• jeff w smith Casting Question

  I have an ArrayList in which each element contains an Integer. I'd like to convert this to a Decimal Array. So I tried making the conversion like this: (decimal[]) MyIntegerArrayList.ToArray(typeof(decimal)) but it fails. Is there a simple way to make this conversion Robert Gentlemen, Your "ConvertAll" suggestion must require VS2005. I'm only using VS2003. So I guess I'm going to have to write my own conversion method and convert each element, one by one. Oh well, at least I know that I wasn't "missing" something very simple. Thank you for responding, Robert From your ArrayList, you can easily create a int[] with the method you already used. Then, ...Show All

• RoobyDoo Converting Double To Integer

  Anyone know how to convert double to integer Thanks, Rob Works like a charm Thanks look in the Convert class: int theValueToConvert = Convert.ToInt32( doubleValue ); I was a little confused about what you meant by "real/true," since the direct cast also converts it to a real integer. From MSDN, it seems that Convert.ToInt32 rounds to the nearest even number when it converts, as opposed to the truncating behavior of casting to int. Personally, I have used the direct cast much more often, in the few situations where conversion is required. is it Ok int intnum=(int)doublevalue; well thats just a ...Show All

• sureshsundar007 Get system language independent Yes No Cancel Retry Abort string from the system

  How to get the string that represents the "yes" string on the local system. If I use... DialogResult .Yes.ToString() "Yes" is always returned. This is good for English systems. But I want it system language independent. On a Dutch system, it should return the string "Ja". I can work with a resource file, but I think it is possible to get these string directly from the system. But I don't know how. Anyone has the code Thx Adriaan The "Yes" in DialogResult is an enum.  ToString() will always return the name of the enum; which is why you get "Yes"--just as you would always get "Win32Windows" when using PlatformID.Win32Windows.ToString().  Currently that is not l ...Show All
