Hello All
I have a group of applications that working on a LAN and there was another application -reporting tool- that may use the databases of all other applications through web services -each application provide a web service to give access to its database-, and this is working good, the problem is that I had to make a new build for the reporting tool each time a new application added to the group, this is absolutely not happening every day, but I was think in an optimized solution, which I think is to make the reporting tool call the IIS in every machine on the network to get the web services that is available, and then provide the admin by a list of the web services then prompt him to add reference to the web services that he wish to connect with, this means that I should add web references at the runtime.
I don’t know if I can call the IIS to do that, or if I can add web references at runtime, but I thought on the problem as a logic which I don’t know if it can be done or not.
my question is, is this can be done?, and how to do it?

If the methods you use in the reporting tool, are the same in each of the web services, you can create your own (single) proxy.
The easiest way is to use WSDL tool and possibly strip off everything you don't need from the generated file. Now you can better control the change of the URL and also other properties of the proxy. Also when you add the generated class to you code, you don't need to add web references anymore.
Hope this helps you,
Mika

Evening all !
Can anyone tell how i declare a list in my class so all the methods can see/access it or is this not possible ?
I've created a list in button code in a form -
List<Animal> zooAnimals = new List<Animal>();
but can't seem to figure out how to make it global so other methods can access it.
I tried
public List <zooAnimals>;
but that doesn't work
Thanks in advance

use the word static before the declaration. But then the list will belong to the class and not the object
|
|
|
|
|
Declare a class (public, static if you want) and define the list in that class. For example:
public static class MyList {
private static readonly List <zooAnimals> = new List<Animal>();;
public static List<Animal> ZooAnimals {
get {
return zooAnimals ;
}
}
}

readonly is not recommended for objects of this sort since it implies the objects of the list are unchangeable when in fact they are. It is a constantly source of errors for novices.

When posting the answer I though for awhile if I should declare the list readonly or not.
When used correctly, readonly eliminates certain problems that can occur if the actual list is changed. I would say that it depends if you want the list to be changed or just to allow to modify it's content. That's why I also defined only getter for the property.
The other thing was that the original question was, how to define a list globally so that others can see and use it. Based on the question my interpretation was (maybe incorrectly) that the list should not be changeable, but it's contents can still be modified.

Whats the difference between
if ((e.Button & MouseButtons.Right) == MouseButtons.Right)
{
}
and
if(e.Button == MouseButtons.Right)
They both work the same
I am unable to understand the use of the logical operator &
and ALSO when I change the & with && it wont work
Can anyone help

Yes, you can by learning what bits are and how the different bit operations work. Perhaps you should start here[^]

They don't actually work the same. If that event was raised with both right and left mouse buttons pressed (eg: e.Button = (MouseButtons.Right | MouseButtons.Left)) then the two snippets would be different. The difference is that the first one checks to see if a particular bit in a value is set and the second checks to see if the value is exactly equal to some other value.
I assume that when you switch & with && you got a compiler error. The single operators & and | are used to perform bitwise operations. The double operators && and || are used to perform operations on boolean values.

Hi,
humayunlalzad wrote: the logical operator &
No, && would be a logical operator, & is a bitwise operator
The following is similar to your code (just assume MouseButtons.Right=1), but may be easier to understand:
for(int i=int.MinValue; i<int.MaxValue; i++) {
if ((i & 1) == 1) Console.WriteLine(i.ToString()+" is an odd number");
if (i == 1) Console.WriteLine(i.ToString()+" equals 1");
}
i & 1 ANDs the bits of i with the bits of 1 (which is all zeroes except for the rightmost bit);
the result is either 1 or 0, and depends solely on the lowest bit of i.
As a result, the former test checks only a single bit (and hits many times), the latter checks all bits in variable i (and hits just once).

I do understand the behaviour of bitwise operatores on Integers. But what I still dont understand is
e.Button how is that an Integer, or what bits does it have or how do we know those bits.
I assumed that MouseButton is an enum and the bitwise operator would work on its underlying byte or int value.
And thanx for the help

Hi,
MouseEventArgs.Button returns a MouseButtons Enumeration, which basically is an int with some
bits set. I suggest you read up on enums, and the Flags attribute if you want to know the
specific details.

Thanx a lot everything is clear now. You were a great help.

you're welcome.

I've scoured the web (well sorta' scoured it anyway) looking for an answer to this question.
I want to rotate a label control so that it's oriented vertically. I've tried a couple of the articles here on CP, but I'm having a couple of issues.
0) The rotated text is incorrectly aligned
1) The rotated text (what I can see of it anyway) is butt-ugly, exhibiting no anti-aliasing at all.
I've tried rendering some text on a bitmap, and then rotating the bitmap, but that ain't working at all (I know it's because I'm not doing it right).
Does anyone know of a decent (free) rotated label control that honors ALL of the alignment and applicable style settings and the system text quality settings?

If you decide to make a custom control check out the Win32 SetWorldTransform call. This will set a transform that even the text drawing API's will how, and still have thinks look reasonable (something that the lfEscapement value completely mucks up). It shouldn't be too hard to do this in .Net. You may also have to drop down and make a DrawTextEx or TextOut call your self - somewhere in the back of my mind I recall one of these calls being the better one to use.

Well, I solved that particular issue by creating the bitmap in a separate class, and then rotating it in the form's OnPaint routine. I have a whole other issue right now.

BTW, I beat the framework into the submissive bitch that she should be, and forced my will upon her, like she was a $2 hooker.

Glad to hear it, cause the whole bitmap rotation thing was an awfully cheap way to go - kind of My Pretty Pony approach if you ask me.

Is that a Texas Special? I don't have firsthand experience mind you, but I'm pretty sure in NYC you're now looking at a $10 hooker, inflation, gas prices, stock market, and so on being what they are.
