I have one Dropdownlist and one listbox. Dropdownlist contains all doctor names and listbox contains specializations.
I have 3 tables (Doctor,DSpecialization and DSpecializationDetails)
DSpecializationDetails-(DoctorId(PK) and DSpecializationId(PK))
Doctor - (DoctorId(PK),DoctorName)
DSpecialization-(DSpecializationId(PK), specializations)
One Doctor could have many Specializations
I want the user to be able to choose 1 or many specializations,
and insert the selections into a table called DSpecializationDetails.
I’m working with Asp.net and C#
Thanks for any help.

Hi
How to fill a picture box by using RGB colors
thanx in advance

Hi,
U can fill the picturebox by setting the BackGround Color property. Use this ode
pictureBox1.BackColor = Color.FromArgb(30, 100, 120);
If u don't want to use the background property You can also create a new bitmap, draw a rectangle, fill the rectangle with a color and set the bitamp as image of the picture box.

Hi,
Windows service dosent have a GUI. So if you want to run Windows application as windows service there are 2 ways of doing it ( atleast, i know this much only )
1) Create a new windows service. copy all code from windows application to the newly create service (without any GUI related code, but satisfying the business logic). Install the service. Run it.
2) Just hide the windows application to a tray icon. In this way, you dont need to copy code. But then the application itself should be bbuilt in such a way that it dosent get stuck for user interaction for its process to continue, but when interrupted, should respond to the user.
I dont know why you want to shift from windows application to windows service. if you could specify some details, then it would be easier to give some specific advice.

Hi,
You want the complete XML File to be encrypted or you want some data in the XML file be stored in encrypted format ?

sir i want to encrypt both the XML structure and the data that i'll pass in to it.
please give me a sample application, so that i can understand the encryption and decryption,
i've gone throwgh the msdn link, even then i request u for a better sample.
i new to this xml encryption and decryption method, Please help me...

Why do you need the data encrypted? Unless you are storing sensitive data, you shouldn't need to encrypt the file.
If you are trying to make sure that no one has changed anything in the file, you can use Signed XML instead. Take a look at http://msdn2.microsoft.com/en-us/library/system.security.cryptography.xml.signedxml(VS.80).aspx[^] for more information.
The big disadvantage to encryption is that it becomes a real pain to debug.

If you are using the XML as a backend database, you are going to run in to a lot of problems. You should really look at using an actual database engine for this. If you need something that is embedded in your application, look at SQL Server 2005 Compact Edition[^], which will give you an embedded database engine.
If you absolutely must use XML and encrypt the entire file, the easiest way will be to treat the XML as a string. You can then use any of the built-in encryption classes in the System.Security.Cryptography namespace.
Essentially, you would want to read the encrypted file from disk and decrypt it into a string, then use that string in the LoadXml method of an XmlDocument. Decrypting would be similar, but you would use the OuterXml property on the XmlDocument to get the XML as a string, encrypt that string and then write it to a file on disk.

hi
I need the C# code for the following:
I am using windows OS.
1)How to get the details of a machine, if we know the machine name or IP address
Details include : BIOS version, boot time, name of user who has logged in, hard disk drive(size of each partition), model of the machine, CPU(processor details), OS Version, network cards, etc.
2)How to detect the softwares installed and their version. This means where the keys are added in the registry and how to get it back?
3)How to detect the various hardwares installed or plugged into a machine?
I know all these are related to Registry.
Please give a detailed reply, ASAP.
Thanks,
SYAMLAL

Hi,
1- For machine details U can get what ever information u need using WMI (Windows Management Instrumentation). For example if u want all information about the CPU here is the code :
string cpuInfo = String.Empty;
ManagementClass mc = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
if (cpuInfo == String.Empty)
{// only return cpuInfo from first CPU
IEnumerator enumer = mo.Properties.GetEnumerator();
while (enumer.MoveNext())
PropName = ((PropertyData)enumer.Current).Name;
PropValue =((PropertyData)enumer.Current).Value;
}
}
Of course u must add a reference to System.Management namespace in ure project.
Fore more information about WMI visit this link : http://aspalliance.com/629[^]
2/ To retieve installed software here some code :
public static void GetInstalledSofts()<br />
{<br />
string uninstallKey = @"Software\Microsoft\Windows\CurrentVersion\Uninstall";<br />
RegistryKey key = Registry.LocalMachine.OpenSubKey(uninstallKey);<br />
if (key == null)<br />
{<br />
System.Console.WriteLine("Unable to open registry key {0}.", uninstallKey);<br />
return;<br />
}<br />
<br />
ArrayList list = new ArrayList();<br />
string[] subkeyNames = key.GetSubKeyNames();<br />
foreach(string subkey in subkeyNames)<br />
{<br />
RegistryKey sk = key.OpenSubKey(subkey);<br />
string prodName;<br />
string uninstallString = (string)sk.GetValue("UninstallString");<br />
string displayVersion = (string)sk.GetValue("DisplayVersion");<br />
string productCode = string.Empty;<br />
<br />
if (subkey[0] == '{')<br />
{<br />
productCode = subkey;<br />
prodName = (string)sk.GetValue("DisplayName");<br />
if (prodName == null) prodName = string.Empty;<br />
}<br />
else <br />
{<br />
prodName = subkey;<br />
}<br />
<br />
}
3- Use WMI to list hardware

Dear All,
How to make sure that controls on the form do not change their location when Form scroll event occurs ? I am having a form and I drag and drop a textbox in it. I enable the scroll event of the form. Now when ever I scroll up/down the textbox control is changing its location i,e. its co-ordinates X and Y.
I am writing the following code snippet in the scroll event,
private void Form1_Scroll(object sender, ScrollEventArgs e)
{
textBox1.Text = textBox1.Location.ToString();
textBox2.Text = textBox2.Location.ToString();
textBox3.Text = textBox3.Location.ToString();
}
Please help me in solving this problem.
Thanx

Here you are not changing the position of the text box. You are just assigning the location to the text property. If you want that the text box should not move even when the scroll bar is scrolled, try to change the location of the text box in the same event. Please check the ScrollEventArgs for the new value of the scroll bar, using which you can change the location of the text boxes.

I want the location of the textbox to remain same(fixed), whenever the scroll event occurs.

Hi,
I got your point already. You dont want the text boxes to be scrolled out of the screen. correct ? Thats why you will need to change the location of the text boxes according to the new values of the scroll bar. In this way your text boxes will appear as if "Fixed"

Hi,
Is it possible to change the priority of the message that is already exists in the Message Queue. Direct APIs are provided to set the priority while posting in to the MSMQ, But I couldn't find out the way to change the priority of the message that already exists in the queue.

Hello all,
I am using a vertical scroll bar. During the runtime, I want the form to be scrolled according to the scroll bar.
Thanks in advance.

You might want to take a look at the AutoScroll property of the form itself as this provides the functionality you're looking for.
