I wrote a program for my company that uses the SQL MSDE. I would like to know what class/function to use to retrieve the SQL server instance, computer name, and the path for the current users My Document folder. I will use this information to create the connection string on the fly. Is that a good idea or bad programming practice? If it is bad, what is an alternative?
Also, whats a good/free installer program I can tinker with?
Thanx in advance!

It's something like Enviroment.GetSpecialFolder to get the My Documents folder ( among others, it takes an enum ).
Advanced Installer has a free version, I've found it quite good.

*grin* I was flat out and going from memory. That should be enough for you to find it, if not, just give me another yell.

Thanx brother..but about getting that info to do on the fly sql connections...good programming practice or not?
UPDATE
I looked at MSDN Library and got this:
[C#]
// Sample for the Environment.GetFolderPath method
using System;
class Sample
{
public static void Main()
{
Console.WriteLine();
Console.WriteLine("GetFolderPath: {0}",
Environment.GetFolderPath(Environment.SpecialFolder.System));
}
}
When I try to type Environment.SpecialFolder, Intellisense does not pop up..is this a valid property in C#? If so, what do I add to it?
Thanx
EDIT
Ok, got it..a environment class and enum

A client recently asked me if I could make a porgram that would have a fairly simple functionality, but with a catch.
When the program is running he wants it to be the only program available. So a user couldn't alt tab and go to another program or minimize the program and open up a web broswer. To get out might require the user to hit escape and type in a password.
I call it "Locking" but maybe there's already a phrase for this type of functionality. Is there?

The program could make itself topmost, I guess. It could also grab the input focus whenever it loses it.

This could be done, but it is better left to Group Policy to do this. There are LOTS of ways to get around this "lock", and your app won't be able to cover them all.

When you say to leave it to Group Policy? I don't exactly follow, how would you do this with "Group Policy"?

Pick up the Windows XP Resource Kit and you'll find out. It's covered in about half of the book. But, to give you a quick look-see, click Start, Run, then type gpedit.msc and Hit enter.

Dear gurus
I have a question to generics at the following code
<br />
class ABC <br />
{<br />
<br />
void fkt<T>(T x) {<br />
double y = (double)x; <br />
}<br />
<br />
}<br />
I get the errormessage: Cannot convert Type 'T' to 'double'.
This is absolutely clear ( the compiler does not know if the conversion is possible and therefore it provides this errormessage ).
My Question is:
In my application T is either 'Int32' or 'Double'. How can I convince the compiler to compile this code for my issues (int32 and double where conversion is in fact possible)?
With kind regards

You have to specify a constraint that says T is is convertable to a double otherwise there is no way to know if X can be converted to a double.

Hi Ray,
thanks for your answer ! ! !
How must I write the code to constrain it to "int32" and "double"?
Best whiches

Sorry I forgot the important part:
private void Test<t>(T q) where T : IConvertible{
double x = q.ToDouble(null);
}

Wow ! ! ! ! !
I just want to say "Thank you".
This helps me very much.
With very very very kind regards.
ups: somuch very's

What out for strings. If you want to be really robust you will have to make a class that can take implicitly convert from doubles and ints instead of convertible.

Nice guy !
At the moment, basic numeric types as int, double, char .... are ok.
Currently I dont need any strings.
I whish you a nice day !

Sorry dear guru.
Midnight has passed here and I have my next problem.
May be I get some help before I go to bed soon
class XYZ {
void fct_1<T>(T x) where T : IConvertible {
double y = x.ToDouble(null);
}
void fct_2<T>(T x, T y) where T : IComparable {
if ( x < y ) {
// some action here
}
}
}
Function fct_1() works well now (thanks for your help)
But function fct_2 makes trouble now
The compiler says now: "operand '<' cannot be applied to operands of type 'T'"
Even if I restriected to 'Icomparable'
Do you have any hints for me?
Thanks in advance
|

I think the following should work:
void fct_2<T>(T x, T y) where T : IComparable
{
if (x.CompareTo(y) < 0)
{
}
}

I'm voiceless.
this also works
I think you joined the microsoft generic development party  )
Again: Thank you very very much.
Now I will go to bed

My pleasure!
Have a good night

Hello,
I am using remoting in my C# 2005 server-client implementation.
In my server channel sink implementation (in ProcessMessage()), I need to (selectively) make sure that the call to "requestMsg.Properties["__MethodName"]" method is not carried out on the server.
Ideally, I want the server to remain oblivious that the client has even attempted to call that method, yet for the called method to return "false" on the client side (if at all possible).
So far all of my attempts resulted in exceptions thrown on the client side... Any suggestions, please?
Thank you,
Victoria

Is it possible to use a variable to update the properties of a button? For example I have a button on my app named One is the following possible if so how do I accomplish this?
string Button = "One";
Button.Visible = true
|
|
|
|
|
I can't get the issue.can you be more specific ?
if Button is a string it does not have a Visible property and if it's a button then Button="One"; is not valid.
|
|
|
|
|
Exactly, I want to be able to assign the name of my button to a variable and then use the varible instead of the button name to adjust the button properties. I do not know if it is possible, honestly I don't believe it is but I just wanted to check here before I gave up on it.
