You don't need framework 3.5 for ForEach, I guess it's just lambda statement that causes error. anonymous method will work.

That's right, but you need 3.5 for the ToList method.

I am trying to add a Arraylist, as a member to another array list.
The problem is, All the members of GroupReqAL are contain the final values of ReqAL. When I debug, first run is fine, in the 2 nd run the ReqAL is added both GroupReqAL[0] and GroupReqAL[1] are set to the latest values of ReqAL and in the 3 rd run GroupReqAL[0] ,GroupReqAL[1],GroupReqAL[2] are set to the latest values of ReqAL... and soon, finally all the members of GroupReqAL containts the latest values of ReqAL. Please advice
int i=0;
int j=0;
ArrayList GroupReqAL=new ArrayList();
ArrayList ReqAL=new ArrayList();
while(i<100)
{
while(j<10)
{
ReqAL.Add(j*i);
j++;
}
GroupReqAL.Add(ReqAL);
i++;
}

That's because you are adding a reference to the same ArrayList over and over again. If you want to add references to separate ArrayList instances, you have to create a new ArrayList each time.
Unless you are stuck with framework 1 you shouldn't use the ArrayList class at all. Use the generic List<T> class.
Despite everything, the person most likely to be fooling you next is yourself.

Doubleclick event does not fire for button. It is because ControlStyles.StandardDoubleClick property is set to false. In order to fire the double click event, you will need to create your own button by inheriting the button and setting ControlStyles.StandardClick and ControlStyles.StandardDoubleClick to true. This can be done using SetStyle method.
The word "politics" describes the process so well: "Poli" in Latin meaning "many" and "tics" meaning "bloodsucking creatures."

hi ,all
a easy case,
year month day
1999 12 2
2000 8 9
2001 9 9
how can i use
listview1.Item.Add(listviewitem) ?
thanks~~~
|

Hi,
what I normally do with listview-items is to create a derived class from ListViewItem, passing the object to display to the constructor and building all subitems within a method called from the constructor.
class MyListViewItem:ListViewItem {
public MyListViewItem(DateTime dtDate):base(String.Empty) {
this.BuildItem(dtDate);
}
private void BuildItem(DateTime dtDate) {
this.SubItems.Add(dtDate.Year);
this.SubItems.Add(dtDate.Month);
this.SubItems.Add(dtDate.Day);
}
}
Then I can use objects from this class to add them to the ListView:
listview1.Items.Add(new MyListViewItem(DateTime.Now));
Look at the following link to get an idea for SubItems
http://msdn.microsoft.com/de-de/library/system.windows.forms.listviewitem(VS.80).aspx[^].
Let me know if this helps you.
Regards
Sebastian
P.S.: The code of MyListViewItem is just an example. Within the BuildItem-method you must take care of already existing subitems etc. (Be sure that the ListView is in "Detail"-View mode.)

That is not possible as it is controlled by the browser.

Hello,
u can try out with DownloadFile() method.
for this u need to include namspace System.Net
then u can try out as
WebClient objWebClient = new WebClient();
objWebClient.DownloadFile(URI, targetfilename);
Check this hope it helps

I think the above solution will solve your problem only when you are using this in a windows application.where webclient will act as intermediate browser and handle the request and target filename will be obviously a local path in your system to which you will be having access. 
But if the requirement is like you have to host the webapp in a remote server and the you are accessing this website from a different client machine, there would be no choice and will be entirely controlled by the browser which you use

I have a DataGrid on my form that users type in numbers. The problem them I am having is that if they do not hit enter after they type in the number, that value is never set. How can I change this so its value is set without the user having to push enter?
Is it the way I am pulling the data or something else?
TixTypeQuanity = dataGridTicketTypes.Rows[dataGridTicketTypes.Rows[dgvr.Index].Index].Cells[4].Value.ToString();
|
|
|
|
|
you can set the AUTOPOST property in asp.
|
|
|
|
|
I was able to fix this as I had the datagrid set as
this.dataGridTicketTypes.CausesValidation = false;
changing this to true fix the issue

i want to read data from a serial port(where a gsm modem is connected). I want to read the reply from modem when an AT command is send to the modem.
i.e for eg. if i send AT to the modem i want to read the reply OK from the modem!
I had used the below codes but the application hangs while executing these lines:
string data = Convert.ToString(serialPort1.Read(buffer, 0, (int)buffer.Length));<br />
string data1 = Convert.ToString(serialPort1.BaseStream.Read(buffer, 0, (int)buffer.Length));<br />
I had also tried
string data = serialPort1.ReadLine();
Below is my full code section:
private void button1_Click(object sender, EventArgs e)
{
try
{
serialPort1.PortName = "COM6";
serialPort1.Handshake = Handshake.None;
serialPort1.BaudRate = 115200;
serialPort1.DataBits = 8;
serialPort1.Parity = Parity.None;
serialPort1.StopBits = StopBits.One;
serialPort1.DtrEnable = true;
serialPort1.Open();
string c = "AT+CMGS=";
string c1 = "\"+6582083412\"\r\n";
serialPort1.Write(c+c1);
string d = "Test message from coded program ";
serialPort1.Write(d);
char[] arr = new char[1];
arr[0] = (char)26;
serialPort1.Write(arr, 0, 1);
serialPort1.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
I would appreciate your help very much, since this is my first time i am trying to communicate with a serial port. Thanks in advance

Hi Aghosh Babu,
It seems like you are try to build an application which send SMS using a connect Phone , and the serial port you are using (COM6) is a virtual serial port (port used to connect to through buletooth or USB ) , so please make sure that you com6 is working , by using Apllication like Hyper Terminal (it comes with windows XP) , try to send AT , and recive OK , if its is working over there , than you can try it in your code (dont forget to disconnect hyper terminal bepore try from you code , other wise it will give error , say port already in use).
I have used the following code recive data that arrives on serial port
private static void SerialPortDataReceived(object sender, SerialDataReceivedEventArgs e)
{
if (_serialPort.BytesToRead > 0)
{
int bytesToRead = _serialPort.BytesToRead;
byte[] dataRead = new byte[bytesToRead];
string linedata;
_serialPort.Read(dataRead, 0, bytesToRead);
linedata = ConvertToString(dataRead);
}
}
private string ConvertToString(IEnumerable<byte> ByteArray)
{
string tempStringToReturn = string.Empty;
foreach (byte bt in ByteArray)
{
tempStringToReturn = tempStringToReturn + Convert.ToChar(bt);
}
return tempStringToReturn;
}</byte>
In the above code SerialPortDataReceived is a event of serial port object , this event is raised when there data arrives on the serial port .
Try out with above information , see if it helps , i need to move now , let me know if you find any problem regarding the same

Hi Bharat,
Thanks for the code... i am now able to read data from serial port.. initially i haven't set my handshake property properly...I used serialPort1.ReadExisting(); to read the data from serial port... i think i will redo my code with yours  ...i hope your code will automatically initiate the method when a data comes into the port...

Gr8 to know that the code was helpful.
