• Visual C# Future C# string optimization directions

  This is a topic of academic interest to me.  Are there any plans to optimize code patterns such as: string results = ...; bool foundSomething = results.ToLower().Contains( "something" ) ) Here, I'm making a case-insensitive search and it seems that ToLower() is an unnecessary use of CPU cycles and memory accesses.  One possible solution, which isn't very extensible, is for ToLower() to do a lazy-copy: it will first make a reference to the input string and add a "use-lower-case" bit.  Contains() uses this bit to do the case-insensitive compare on the original string.  Brian ...Show All

• Windows Forms Style object

  Is anybody know how to change the style (such as color, font ...) of objects (like button, combo ...) in a centralize area of a Windows application.  I mean, I want to be able to have a functionnaly similar to cssStyleSheet (used in ASP.NET) but in a Windows application.

• Visual C++ Simple Simple COM

  Hi! I do all my programing stuff in c#.. but i need some plain C or C++ code sometimes.. and i need to interact classes made from C/C++ to C#. As i heared this is done with COM`s Can anyone show the simpliest COM made in C/C++.. that has a Class named Test and a method int Add(inta, int b); that return the sum of them.. Please make it simplie as possible.. coz i`m not really good at C/C++.. COM things.. I would like to dispel the perception that you need to COM to integrate C/C++ code with C# code. I would wrap your existing C++ (not C) code with C++/CLI instead and bypass all the COM plumbing. The only time you need to use COM in .NET ...Show All

• Visual C# how to communicating an object from one comp. to an other one?

  I've an OleDbDataReader Object in my app. and I wana communicate this object to an other computer. Is it possible if yes how to While it might be TECHNICALLY feasible to do this -- it would probably help a little if you gave the reason that you need to do this. The only reason I can think of is some kind of proxy type situation [I can communicate with Sql Server X but you can't -- I supply a proxy object so that you can]. More than likely, your best bet would be to do one of two (2) things (1) Just pass the necessary information to the other computer so that it can create its own oledbdatareader (2 ...Show All

• Smart Device Development Debugging and deployment problems on WM5.0

  Hello I have a couple of questions I can't figure out on my own. I've written a program that runs fine when I use the PocketPc 2003 emulator. It also builds for smartphone 2003 and both smartphone/pocketpc WM5.0. The problem is that it doesn't run on other emulators than the pocketpc2003.

• Windows Forms Why is VS 2003 Designer Mode so slow in loading some forms?

  On my forms with many (50+) controls it takes many MINUTES to load the form in designer view. The problem is magnified with forms using UserControl derived formss. I'm using a more than adquate system too. Is there a fix or a workaround to address this or at least improve it because it really hinders rapid development when you have to wait minutes each time the designer needs to be re-loaded, which is basically every time the header file is modified.
