It's rude to ask the same question again. Also, you've been given the answer in your first post - namely that there's no "proper" solution for what you're trying to do.

Hello All,
In order to display a combo with all servers on my domain, I am using this code:
string domainName = Environment.UserDomainName;
DirectoryEntry domain = new DirectoryEntry(
String.Format("LDAP://{0}/CN=Computers,DC={1},DC=com"
, domainName
, domainName));
foreach (DirectoryEntry child in domain.Children)
{
this._comboBoxServers.Items.Add(child.Name.Substring(3));
}
domain.Dispose();
At the begining it worked great, until it stoped returning the full list and returns only one computer "BEServer".
When I open an Explore window to look at my network places, in the domain I just retrieved sometime see the all the computers of the domain and sometimes only one icon "UTSC".
Does anybody have a clue ???
Thanks
Calanit

I have a project that's web service includes virtual directory and to call the virtual directory in the project ı create an asmx file called 'Directory' and when try to run the asmx on the web, ı got this error.
Besides this, in the project, i declared the virtual directory in the localhost(as in default web site), but i will publish the project, and when users install the program to their pc's, can they see and use the virtual directories in the server. When i research on the web, i see the virtual directory is only in the localhost Can i declare the virtual directories on specified web service like:
"IIS://LocalHost/w3svc/1045426499/Root/Data/",@"c:\Program Files\xxxxx\yyyy\Data"
Could you help me, please!
The error:

I don't know what exactly you wanted to install into Client PC. I think you need to type correct Web Address to call Web Service.
"Http://LocalHost/VirtualDirectoryName/xxxx.asmx"
Visual studio Map virtual Directory automatically.
Another way you can open IIS and then click Map Virtual Directory. You will see your project. Just right click on ASMX file and select show on browser. it should be working.

Your second form shouldn't know nor access the first form.
When opening the second form you just pass the id to that form.
There are several way's to do this.
1: Make a property on the second form and set this property from the first.
2: Make a constructor on the second form which accepts the id (and use that constructor on the first form)
3: (not to be used unless the id has to be used on several forms) Make a new class with a public shared variable in it and fill that one on the first form. Then access it on the second form
On a side note don't say that it's urgent, all questions are.

Form2
public partial class Form2 : Form
{
private int iid;
public Form2(int id)
{
InitializeComponent();
iid = id;
}
}
Form1: (opening from form2 is in a button here)
private void btnOpenForm2_Click(object sender, EventArgs e)
{
Form2 frm = new Form2(1);
frm.Show;
}
Now you can use the id anywhere you want on form2

Create a rectangle of the appropriate size and draw the image in the rectangle.

-I have a picturebox 300*300 in size
-And a jpg 1200*1200 pixel 150 DPI
How to draw a quarter of image to picturebox with original size?
Thanks everybody
|
|
|
|
|
Not a quarter but a 1/16th.
How does the JPG exist? Is is a file, a Bitmap instance or what?
Regards,
Rob Philpott.

First thanks for answer.I load jpg to image object and draw a part of image(size=250*250) in picturebox.
Problem is image was draw in picturebox is smaller than i expect.(because i open jpg by ms paint and i saw 250*250 in ms paint is bigger 250*250 i draw in picturebox).
Hope you can explain.
Thanks.

Hmm. Not sure, although it sounds like a logical unit vs. device unit problem, possibly taking into account the DPI of your graphics set up.
My graphics card/monitor displays things at 98 dpi, so the scaling might be from the native 150dpi to the 98 (if you are the same), although I would expect things to be bigger than smaller in that case.
The DrawImage method of the Graphics class allows you to scale things, or the ScaleTransform method allows you to change the 'resolution'.
Regards,
Rob Philpott.

Hi All,
I have developed an application in c# 2.0
I am going to launch my desktop application in market and I have 2 concerns regarding security of my application
1. Application licensing
2. database security
I don’t want anyone to use multiple installations of my application while he has paid me for 1 license and have a setup, how to prevent it?
I don’t want to show off my sql server schema while I have to deploy a database on client system with user id and password, how to attach an .mdf file with the sql server or anything else so that no one can check my sql database?
Hope you reply soon
Regards
Kaleem Ullah

It is very tough to get a 100% perfect licensing system. I have used APIs from this[^] for my application. They are good and provide a decent way for managing the licenses and activations.
LogiSmith wrote: I don’t want to show off my sql server schema while I have to deploy a database on client system with user id and password
If you want to deploy the DB in user's system, it is very tough to secure it as user will have complete access to it and can hack in easily. Why don't you create a webservice which interacts with database located on your server and your applications interact with this webservice. So users will not have access to databases.
