• JohnD74 Exclude element from foreach index (MenuStripItem) HELP!

  Hello! I have a foreach loop. How can I exclude one of the elements from being indexed: I have a foreach loop setting a property for each of the items in a ToolStripMenuItem category, but one of the items is a ToolStripSeperator, and I would like to exclude it so the foreach loop would set the property for all of the items EXCEPT the toolstripseperator. How can I do that Matt Maybe not an exception then, but I bet there is a whole slew of underlying code that traverses through the type information tree recursively, looking for the type. Which is a lot slower than just calling a virtual function. I take your point about GetType not supporting derived classes though. ...Show All

• S_Parikh C# versus COM

  Is C# really just making calls to pre-existing COM C++ dlls via the .NET Runtime In the context of the language itself. For example, some third party software vendors give you a C# api or a Java api to their product, when really all that is happening, at least in the Java api, is JNI making calls to COM components. Is C# it's own language, or is it just another layer on top of COM, which happens to benefit from a CLR, aka .NET runtime. My take.  .NET is a complete replacement to COM, but they share many traits in common.  Its metadata support is like COM typelibs (but more powerful of course) to represent types.  CLR also introduces a bytecode (called IL) used to encode the program itself.  ...Show All

• Michal Konecny Check if a remoting service is up and running

  Hi, I need to implement some kind of watchdog which checks if a remote service is running (and,if it's not, supposing the server went down, starting it on another machine) but I'm still trying to figure the proper way of doing it. I was thinking about using .NET Remoting, but I'm not sure it's the right way. Does anyone have any suggestion Thanks in advance for your kind help ! You can configure or monitor the state of services using ServiceController class. ServiceController class has a machine name property. So you can monitor or manage remote services too. But the running application's (your application' i mean) Identity must have rights to do so, on remote machine. So you may have to ...Show All

  I want to develop a software in which user can interact with the buttons via a touch screen.

• Vishalbhambure Need help with enum and color assignment

  Hi, I need help with some enum and color assignment. This is what I need to do. I have an enum like: public enum statusFlag { Unknown = 0, Easy = 1, Medium = 2, Hard = 4, ExtremlyHard = 8 } From xml: (not sure how this is repesented) Unknown = Black Easy = Green Medium = Yellow Hard = Orange ExtremelyHard = Red Now, I have a set of color for each of the different status flags. These colors are user definable. Possibly will reside in an xml file.

• Will Merydith BackgroundWorker

  Hi I have read the backgroundworker overview and usage on msdn and would like to implement on my project. Initially i put the component on a form of my appplication and it hits the error relates to cross-threading....from UI controls. Thus I decide to zoom in to the method that isreally time-consuming and use the backgroundworker.., instead of just throwing a 'high level' method which is found on the form itself. However I found that the line of code that takes a long time ( which is the one retrieving data from the db) found inside the controller class. How do i plug in the backgroundworker component into the non-UI controller class I mean the examples given from msdn applies the component on the form and now i am dealing with a single cl ...Show All

• Elham Sarikhani How to Enumerate StringBuilder object with null character as delimiter between strings

  hi all, i have a StringBuilder object with unknown number of strings each string followed by a null character. i am getting the only first string by whatever the parsing technique i used because of null character. any suggetions thanks and regards ranadheer. It's the CLR marshaler that cuts the string at the first null character. If you change the type from StringBuilder to char[] you should get the entire buffer back. All, I have a similar situation.  In my case it is a return value from a function that I am trying to run.  The returned string is supposed to be a set of null-delimited string values finally finished off with an additional null.  i.e. Value1<nul ...Show All

• ray_newbie_SSIS Why don't we use header file and Main in class

  Hi 1-)In c# why don't we need header files What does c++ miss.So it needs header file but c# not. 2-)In c++ main() is not in a class.Main() is called by OS.It is a special function.But in C# it is also in a class.For example: class Exercise { static void Main() { Console.WriteLine(); } } Here this is confusing thing.Why do C# designers force us to put main in a class Does OS instantinate Example class for calling main().If not what is the magic behind this rule Thanks. ok my first questions answer is metadata.Thanks carlop.
