Hello eveyone,
I have a DataGridView which holds columns such as (FirstName, LastName Email, HomeAddress). I would like to create a filter which filter the data base on the LastName. I would like the filtering happens as soon as the user starts to type in the first text letter in an designated area used for filtering the data. Let's say, once the user types the first letter "K" a list of last names starting with "K" appears. once the user types the second letter "h" the filter result display the lastname starting with "kh" and so on. I am not even sure what this functionality is called! I just called it "Active Filtering".
I was thinking of having a comboBox for the typing area and displaying the result of filtering. I am not sure if this is the right approach.
Can someone be kind enough to tell me how I can get this done and what is the right approach for this. Is the any particulare Controller than I can use for this.
Any information would be appriciated. Thank you very much and have a great day.

//load data in DataTable or DataSet
private void LoadData()
{
this.sqlDataAdapter1.Fill(this.ds_ordres1.Tables["orders"]);<br />
this.dataGridView1.DataSource = this.ds_ordres1.Tables["orders"].DefaultView; }
In TextBox_Changed event handler of Your Search TextBox, write This Code :
private void textBox1_TextChanged(object sender, EventArgs e)
{
//in this example, row filter set on customerID
this.ds_ordres1.Tables["orders"].DefaultView.RowFilter = "customerID like '" + this.textBox1.Text + "%'";}

The reply posted by hdv212 is correct.
You can also achieve the same by introducing a Binding Source.
--------------
BindingSource myBindingSource = new BindingSource()
private Form1_Load()
{
myBindingSource.DataSource = myDataSet;
myBindingSource.DataMember = "myTableName"; // TableName on the myDataSet
myBindingSource.Filter = "";
myGridView.DataSource = myBindingSource;
}
Now in your TextBox_Changed Event write the following code
{
myBindingSource.Filter = "lastName = " + textBox1.text;
}

So I've got this app that requires the use of a username and password.
They have to be specific ones too though. They have to match the username and password used to log on to the domain.
In all honesty, I do *NOT* want to have to ask for those credentials. I would much prefer simply pass them along.
So here is my question... the function I need to use requires 3 parameters; username, password, and domain.
Is there a way that i could do something like the following?:
login( WindowsUsername, WindowsPassword, WindowsDomain )
I really don't want to have to do any kind of authentication, it'll be done on the server's end. All I want to do is be a passthrough.
Is it possible?
If so, how?

You won't be able to get the password, unless you create a form to capture it. This would be a way to do it though.
<br />
[DllImport("advapi32.dll", SetLastError = true)]<br />
public static extern bool LogonUser(String lpszUsername, <br />
String lpszDomain, String lpszPassword,<br />
int dwLogonType, int dwLogonProvider, ref IntPtr phToken);<br />
<br />
[DllImport("kernel32.dll", CharSet = CharSet.Auto)]<br />
public extern static bool CloseHandle(IntPtr handle);<br />
<br />
IntPtr tokenHandle = new IntPtr(0);<br />
const int LOGON32_PROVIDER_DEFAULT = 0;<br />
const int LOGON32_LOGON_INTERACTIVE = 3;<br />
<br />
tokenHandle = IntPtr.Zero;<br />
<br />
if(LogonUser(txtName.Text, DomainName, txtPwd.Text,<br />
LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT,<br />
ref tokenHandle))<br />
{<br />
WindowsIdentity WinIdentity = new WindowsIdentity(tokenHandle);<br />
System.Threading.Thread.CurrentPrincipal =<br />
new WindowsPrincipal(WinIdentity);<br />
}<br />
If the user has been authenticated on the domain you will have the WindowsIndentity available. Have you done a search for Single Sign On (SSO)?

Nope, never searched for SSO. And, to be PURELY honest, I've never even heard that term before. On that note, I'm searching for it as we speak...
Although you've got some pretty cool code there; I can see what you are doing with it, but it isn't what I need to do.
Sadly this looks like it would be for a prompt asking the user to enter his/her credentials and then verifies if they are correct.
I do not wish to do this. All I want is to simply use the same credentials from the Windows domain logon and pass it on without verifying or asking for it.
**EDIT**
I searched for SSO, and I think it's a bit too big for this small app. Perhaps in the future if I get promoted to being an actual full-time app developer, then maybe, but for now, WAY too big... But thanks for that insight; it opens my eyes to some other possibilities.

It is impolite to state urgent in your subject line, and outright rude to do so if it is not really something urgent. Let your subject line be something that describes, briefly, your problem.
Please read the message board rules[^]

Hints:
(1) Learn a programming language.
(2) Code a firework animation using the above language.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

I recommend c# (but then I'm partial) try this:

You may not even need to learn a programming language to do this and it could be approached from other avenues than programming. Are you wanting to learn programming and think this would be a cool project or do you want to do a fireworks animation and think programming is the right way to approach it? Put this in context and then define what you mean by fireworks animation and exactly what you expect to see when you're done.

Actually I alredy know a bit about programming [^] and I don't need to do a firework animation.
Anyway, thank you for the suggestions.

If you don't want to hard code a firework animation you could possibly create an animated gif file with Animation Shop or a PhotoShop program and just run through the frames at specific time intervals.

1 - read the FAQ on how to ask questions
2 - unless you're saying you know ALL languages, choose one and learn it, and don't expect to be writing a firework animation in that language for at least 12 months.

Hi All
I'm Create a Generics class and i need to write a function return lis of object stored on it but i have a problem as following:
I want to compare if the Generics type is the same of the created class and if its the same i want to use a same method and if not the same type of the created class return the object value .
example:
class myList
{
Array MyArray;
public myList()
{
_MyArray=new Array();
}
public void add(T value)
{
_MyArray.add(value);
}
public object[] List
{
//here is the problem
//Array<object> temp=new Array<object>();
//if T is myList<>
//{
// foreach(T item in _MaArray)
// {
// temp.addRange(item .list);//use list method
// }
//}
//else
//{
// foreach(T item in _MaArray)
// {
// temp.addRange((object)item);
// }
//}
}
}
{
myList AList=new myList();
myList BList=new myList();
BList.add(1);
BList.add(2);
BList.add(3);
AList.add(BList);
//BList.list === {1,2,3}
BList=new myList();
BList.add(4);
BList.add(5);
BList.add(6);
AList.add(BList);
//BList.list === {4,5,6}
//AList.list === {1,2,3,4,5,6}
Note:I know there is an exist class List but This is just an example i need to know how can i do the list function that's it
thank you,

thank you Mark
this is the correct code but I need just how can i call a function in this example list for the generics T(((T)item) .list) or use it like the class( myList<t>)
plz reply me as soon as possible
//--------------------------
myList<mylist<int> ///.list =={1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,80,90}
[0]myList<mylist<int>>///.list =={1,2,3,4,5,6,7,8,9}
[0]=myList<int>;///.list =={1,2,3}
[0]=1;
[1]=2;
[2]=3;
[1]=myList<int>;///.list =={4,5,6}
[0]=4;

[2]=myList<int>;///.list =={40,50,60}
[0]=70;
[1]=80;
[2]=90;
//---------------------------
thank you in advance,
example:
class myList<t>
{
Array MyArray;
public myList()
{
_MyArray=new Array();
}
public void add(T value)
{
_MyArray.add(value);
}
public object[] List
{
//here is the problem
//Array<object> temp=new Array<object>();
//if T is myList<>
//{
// foreach(T item in _MaArray)
// {
// temp.addRange(((T)item) .list);//use list method
// }
//}
//else
//{
// foreach(T item in _MaArray)
// {
// temp.addRange((object)item);
// }
//}
}

{
myList<mylist<int>> AList=new myList<mylist<int>>();
myList<int> BList=new myList<int>();
BList.add(1);
BList.add(2);
BList.add(3);
AList.add(BList);
//BList.list === {1,2,3}
BList=new myList<int>();
BList.add(4);
BList.add(5);
BList.add(6);
AList.add(BList);
//BList.list === {4,5,6}
//AList.list === {1,2,3,4,5,6}

No, a generic class would be something like this*
public class MyList<T> : IEnumerable<br />
{<br />
private List<T> m_InternalList;<br />
<br />
}
As in the example, now you have a Generic class that can support a collection of objects in a type-safe manner and gives the ability to iterate through that collection.
*disclaimer: Not 100% complete and acccurate code, just psuedo code so don't complain;P

i want to send 6 datas from microcontrol to Visual c# with serialport.i create byte array variable in c# for saving my serial datas.but when i send datas so synchronization problem becomes.every time i see 255 at the first data why?i get datas and i show them to textboxes.what kind of problem can be?
my code is:
serialport_DataReceived(.........)
{
serialport.read(variable,0,6);
}
could be buffer problem?

Make sure you're addressing the right serial port.
Device Manager > Your serial port > Properties > Resources > I/O Range (Get the range and maybe translate it to Decimal figures)

i have to read data from an excel file and compare it with
data from sqlserver ...how can i read data frmo excel into such a strucutre so that i can compare data...
urgent help needed.........

I'm using VCS Express 2005.
I have a lot of property definitions in different classes like
public class MyEntity {
public string somestringfield {
get { return (string)Row["somestringfield"]; }
set { Row["somestringfield"] = value; }
}
public string someotherstringfield {
get { return (string)Row["someotherstringfield"]; }
set { Row["someotherstringfield"] = value; }
}
}
When template changes I must manually change it in hundreds of places.
I tried to use template
#define StringFieldTemplate( propname ) \
public string propname { \
get { return (string)Row[propname]; } }
set { Row[propname] = value; } \
};
public class MyEntity {
StringFieldTemplate("somestringfield2")
StringFieldTemplate("someotherstringfield2")
}
But got error.
How to implement this ?
