Hi,
I'm displaying a jpg file in a Panel control with a "stretch to fit" option. When I start resizing the form that owns the panel the image resizes with it, but it flickers and it's really annoying. Is there a way to eliminate this?
thanx

Use the SetStyle method to turn on double buffering.

Hi,
I've already tried this, but I can only call SetStyle on the form containing the panel. The flicker is still there, though.

The Panel needs to be double buffered. If you can't call SetStyle externally, derive a class from Panel and try that

Just tried it.. same thing.

Found the problem: I need to set AllPaintingInWmPaint as well. So it's like this:
SetStyle(ControlStyles.UserPaint,true);
SetStyle(ControlStyles.AllPaintingInWmPaint, true);
SetStyle(ControlStyles.DoubleBuffer,true);
thanx

As someone else said, WMI. The problem is, you'll find you can't access it unless your user is admin.

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);
}
