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;
[1]=5;
[2]=6;
[2]=myList<int>;///.list =={7,8,9}
[0]=7;
[1]=8;
[2]=9;
[1]myList<mylist<int>>///.list =={10,20,30,40,50,60,70,80,90}
[0]=myList<int>;///.list =={10,20,30}
[0]=10;
[1]=20;
[2]=30;
[1]=myList<int>;///.list =={40,50,60}
[0]=40;
[1]=50;
[2]=60;
[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.

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

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 ?

I use DataGridView containing DataGridViewComboBoxColumn column.
Combobox column displays dropdown list opening selection triangle in all rows. This covers part of visible data if columns are narrow.
How to force dropdown list opening control to appear only in active (current) row ?
Andrus.

To reproduce
1. Run the code.
2. Open dropdown list
Observed:
Dropdown list width is same as column width
Expected:
Dropdown list width must be greater than column width
How to make dropdown list width greater than column width in DataGridView ?
Andrus.
using System;
using System.Windows.Forms;
class Form1 : Form {
[STAThread]
static void Main() {
try {
Application.Run(new Form1());
}
catch (Exception e) {
MessageBox.Show(e.ToString());
}
}
private DataGridView dataGridView1 = new DataGridView();
public Form1() {
Controls.Add(this.dataGridView1);
Load += new EventHandler(Form1_Load);
}
private void Form1_Load(object sender, EventArgs e) {
DataGridViewComboBoxColumn
col = new DataGridViewComboBoxColumn();
col.DropDownWidth *= 3;
dataGridView1.Columns.Add(col);
}
}

hi
i want to search by string with pattern, but i want to tell to my regex object that ignore some unicode characters or diacritics (such as "ًٌٍَُِّ") in string, but
how to do ?
|
|

|
|
Hi!
You can explicitely specify a character not within a range by using ^ as first character in the character selection, for example [^abcl-p] means "any character except a,b,c and l to p".

Hello all,
i've written some code that displays a ball bouncing around inside a windows
form. In an attempt to eliminate the flickering of the ball i copy-pasted this
into the the Form's constructor:
<br />
this.SetStyle(<br />
ControlStyles.UserPaint |<br />
ControlStyles.AllPaintingInWmPaint |<br />
ControlStyles.DoubleBuffer, true);<br />
Now when I try to run the code I get this error message. Does anyone know why? or know another way to stop this flickering. Thanks

hello!
I have 2 problems with a comboBox and a dataGrid.
The first problem is that when i'm selecting a table from the comboBox it's ok, but when i select the second or the third table it's not very good. I have too many lines and columms remaining from the first selected table...i must clear that table or datagrid.
The second problem ... i want that my selected table fit in the dataGrid.
This is my code:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
alege_tabel = comboBox1.SelectedItem.ToString();
dataSet1.Clear();
SqlCommand sel = new SqlCommand();
sqlDataAdapter1.SelectCommand = sel;
sel.Connection = this.sqlConnection1;
if (alege_tabel == "Oferte")
{
dataSet1.Clear();
sqlDataAdapter1.SelectCommand.CommandText = "select * from Oferte";
sqlDataAdapter1.Fill(dataSet1);
dataGrid1.SetDataBinding(dataSet1, dataSet1.Tables[0].TableName);
}
if (alege_tabel == "Locatie")
{
dataSet1.Clear();
sqlDataAdapter1.SelectCommand.CommandText = "select * from Locatie";
sqlDataAdapter1.Fill(dataSet1);
dataGrid1.SetDataBinding(dataSet1, dataSet1.Tables[0].TableName);
}
if (alege_tabel == "Transport")
{
dataSet1.Clear();
sqlDataAdapter1.SelectCommand.CommandText = "select * from Transport";
sqlDataAdapter1.Fill(dataSet1);
dataGrid1.SetDataBinding(dataSet1, dataSet1.Tables[0].TableName);
}
if (alege_tabel == "Rezervari")
{
dataSet1.Clear();
sqlDataAdapter1.SelectCommand.CommandText = "select * from Rezervari";
sqlDataAdapter1.Fill(dataSet1);
dataGrid1.SetDataBinding(dataSet1, dataSet1.Tables[0].TableName);
}
}

Without seeing your code it is difficult to help you out, but I am guessing that you are setting your Path variable when the openfiledialog returns.
Note you can also use FileInfo to get the path of a file.

Hi,
when you specify a relative file (a partial name) the "current directory" gets involved.
This CD may get changed in many ways, e.g. by showing an OpenFileDialog,
SaveFileDialog, ...
It depends on their RestoreDirectory property (which modified the behavior the
second time you show such a dialog).

hi
in my windows based application i need to export data from grid to excel,word. iam very new to c#.net.please kindly help me.

hi,
you can use Excel API for that purpose.
Just include Microsoft Excel component in your project's reference and you will be able to use Application.Excel component.
