Re: Database connection in c# Ed K22-Apr-03 5:12 Ed K 22-Apr-03 5:12  We use a configuration file for the connection information. The strings are encrypted for security. if there is a change, we can adjust the connection strings without compiling and deploying. ed Regulation is the substitution of error for chance. Re: Database connection in c# nthomson22-Apr-03 5:24 nthomson 22-Apr-03 5:24  The application uses the username and password that the user provides, not a default system account. Therefore it picks up the database security/permissions to tables/views etc. Any thoughts about securing the connection string in this sort system. Thanks Re: Database connection in c# Ray Cassick22-Apr-03 5:35 Ray Cassick 22-Apr-03 5:35  Build your connection string externally and use tokens for the username and password that can be replaced through code before they are used. I like to use [%USERNAME%] and [%PASSWORD%] as my tokens. Paul Watson wrote: "At the end of the day it is what you produce that counts, not how many doctorates you have on the wall."

Re: Database connection in c# nthomson22-Apr-03 6:35 nthomson 22-Apr-03 6:35  At the moment I have a private member variable with I store the connection string in. I make this variable accessible through a public static property. What are the benefits of using the token methods? Is the static property a good or bad way to store the connection string. Getting back to the orignal post what do people think good practice is for handling database connections? Any converters for C++? Kant22-Apr-03 3:31 Kant 22-Apr-03 3:31  Are there any converters for C++ to C#? I googled but didn't come across any. Anybody know one? Don't and drive. Re: Any converters for C++? Stephane Rodriguez.22-Apr-03 4:40 Stephane Rodriguez. 22-Apr-03 4:40  - code converter ? the whole point of the CLR (Common Language run-time) is to make assemblies interoperable. Build one with MC++, another using C# and also using the first assembly. IJW! - automatic method call converter (better known as P/Invoke) ? Not yet. Here is an interesting site[^].

It's good to learn, but unless it's real work, you might uselessly have to cope with structures that in C++ world are tightly coupled with memory and buffers, while .NET and C# in particular provides less access to it. (in practice, you can do anything you want, just like with C++, but you need to go pretty much hardcore and doing so there is no point in doing C# at all). In case you want to go on with brutal code conversion, don't hesitate to have a look in MSDN first. There are a few interesting type mapping tables to learn. Kant wrote: Any samples? There are simple steps. - start VS.NET, create a MC++ user library project. Add your code. Get the assembly compiled. Let's call it Assembly1. - create a C# project, for instance using the Windows Application template. Add a reference to Assembly1, and add using Assembly1; in your code. Doing so, automagically intellisense brings you all types from the Assembly1 metadata. Add code, compile, run. You've got your first language interoped sample! A sample of MC++ mix mode ? Nish has one[^] for you. Re: Any converters for C++? Kant22-Apr-03 6:01 Kant 22-Apr-03 6:01  Thanks S. Rod. Are you by any chance MCP.net?

Stephane Rodriguez.22-Apr-03 6:41 Stephane Rodriguez. 22-Apr-03 6:41  Eh eh, the only label I would accept is Bill Sergio's son. Just kidding, bwahahahahahahaha!!!! Seriously though there are so many MCPs or whatever so-called experienced guy around, that there is no point any longer in being one. Often they are experienced, but I wonder whzt it brings them in the end. It is my experience that diplomas or labels are one thing, and the ability to communicate is another. What brings value is, and this is not going to change anytime soon, is a good asset of relations and friends in other companies. VS .NET Startpage only shows "My Profile" STW22-Apr-03 0:24 STW 22-Apr-03 0:24  I've installed VS .NET on my machine. As I started up .NET, the Startpage only shows "My Profile" on the left menu. I was used that the last opened projects were listed on the right. The settings for the startpage are correct. Setting "Reset Window Layout" does nothing change. Does anybody know how to solve this problem or to reforce VS .NET to show the correct entry-page? Thanks! Stefan Re: VS .NET Startpage only shows "My Profile" Dire_st22-Apr-03 7:40 Dire_st 22-Apr-03 7:40  um, under tools and options, and in th Enfironment under General, there is a drop down with a heading of "At startup:" and you can specify the last loaded solution. I hope this is what you need.

Steven Behnke21-Apr-03 14:18 Steven Behnke 21-Apr-03 14:18  Hey guys, I'm trying to develop a C# User Control that allows me to send key events. I can use SendKeys.Send() no problem, but it focuses the button so that the button recieves the keydown/keyup/keypress events. I've tried to make my own button and override WndProc(). I'm blocking WM_FOCUS = 7, but no luck. Does anyone have an idea? Thanks, Steven Re: Focusless button? Steven Behnke22-Apr-03 7:02 Steven Behnke 22-Apr-03 7:02  For the moment I've used labels, SendKeys.Send() and onClick for the labels. Let me know if anyone finds a better solution with buttons. Thanks, Steven .config Kant21-Apr-03 11:48 Kant 21-Apr-03 11:48  I have a question reg. the .config files. I know that by using the .config file you can redirect the application to use a different version of an assembly or look in a different location for an assembly. Do we have to use same public key which the application expects? What happens if I don't provide it? Don't and drive. Re: .config Paresh Gheewala21-Apr-03 12:32 Paresh Gheewala 21-Apr-03 12:32  if you are loading dynamically, use Assembley and then check version, and major, minor . need to compair versions and based on that u load that. check Reflection and Emit classes. What does "event" do to a delegate member? Alvaro Mendez21-Apr-03 11:38 Alvaro Mendez 21-Apr-03 11:38  I've been reading up on delegates and events lately and I'm really confused as to what the event keyword does. Does it actually do anything? For example, I have this piece of code inside my class: public delegate bool Validator(char c); Then I define two members: protected Validator dVal; protected event Validator eVal; And I use them: dVal += new Validator(Char.IsDigit); eVal += new Validator(Char.IsDigit); How is eVal different than dVal? They both behave identically. I appreciate your enlightenment. Regards, Alvaro When birds fly in the right formation, they need only exert half the effort.

Eric Gunnerson (msft)21-Apr-03 13:18 Eric Gunnerson (msft) 21-Apr-03 13:18  Events are like delegates except for two things: 1) They're protected so that users can't overwrite them 2) They can be stored in a sparse manner.
