but ok, I don't want to argue with that. The result is that I have to code the login prompt myself.

Hi everyone....
Can anyone tell me if its possible to autosearch a datagrid if the user starts typing on it ?
For example if the user starts typing in a Code field, the datagrid must go to the first location equal to the character pressed etc. until a code is found. Keypressed property ?? Please need help !

Are you talking about a winform or asp.net app?
If it's winform, you should be able to subscribe to the keydown (or keyup) event. Look at the args to the event and then set the selected index in your grid to whatever row (and whatever column in the row you're talking about) matches the key.
If it's asp.net, you could hook up a javascript function and try to perhaps set a background color on one of the rows. But that will be quite difficult as you will have to interogate the generated table's cell values (innertext i think) and then set a background color on the row with the matching value.
Another way to go might be to put a text box up above the grid and a button beside it that says something like 'find'. Let them type a text fragment into the box and then use the button's event to search the grid contents.

Yes im talking about a windows form. I did the textbox and button thing but i want as less buttons as possible. Im trying the keydown event ... but having some trouble with it. The datagrid wants to refresh and get the data from the dataset again but i just want it to scroll down to the letter, letters or word ...

Probably not exactly what you are looking for but I wrote an article which filters the DataGrid. You can find it here[^].

Something like that , just without the testboxes and filter only by one field.
Thanks anyway

Hello Friends,
I am facing some problem in Date Time in c#.
I wrote program like this
string strdt= "06/19/2006"; //mm/dd/yyyy
DateTime dt= Convert.ToDateTime(strdt).ToString("d") ;
When I execute this then I get value in dt like "6/19/2006"
But, Actually I need value in dt "06/19/2006" in this format. I mean to say Zero with Six.
How can I solve this problem?
Any help is appreciated
Thanks,
Rajesh

See this:
Console.WriteLine(DateTime.Now.ToString("d", DateTimeFormatInfo.InvariantInfo));

If you look at the documentation it states that if the day is a single digit it will be returned as a single digit. I would think it doesn't matter how it is stored internally, but how it is displayed. If you want a day to be displayed with a leading zero, use "dd" in the format string.
Here is the link from the MS help files:
ms-help://MS.VSCC.2003/MS.MSDNQTR.2003FEB.1033/cpguide/html/cpconcustomdatetimeformatstrings.htm

use
string[] str=dt.Date.GetDateTimeFormats('d');
Take whatever the format you want from str array

I think the ToShortDateString does it automatically.
DateTime date = Convert.ToDateTime(strdt).ToShortDateString();
|
|
|
|
|
DateTime dt = DateTime.Parse(strdt);
Console.WriteLine(dt.ToString("MM/dd/yyyy"));
Try code model generation tools at BoneSoft.com.

Hi,
Here is the c#.Net code:
TcpClient client = new TcpClient();
client.Connect(clientMc , 9333);
NetworkStream ns = client.GetStream();
Note: clientMc is string storing remote machine name as specified in hostfile.
Problem: If clientMc is localhost, the client is getting connected.
If clientMc is the name of other remote machine, it is not connecting and it is waiting over there.
Could you please suggest me?
Thanks

Do you have something listening on that port on the other machine? Are you getting an exception?

Sounds like you should break out your text book, and see if you can get this information from there. That's why it's called homework.

hi all,
how will i be sure that everything in buffer is read. nothing to read anymore?
i want to call a function after i read all data in serialport but dont know how i should code for check condition ?
help please,
bye.

If you know your end char of byte strem to read you can use the following code
<br />
SerialPort SPort = new SerialPort();<br />
char chCarriageReturn = '\n';
string strSerialPortReturnData="";<br />
int inReadchar;<br />
while ((inReadchar = SPort.ReadChar()) != Convert.ToInt16chCarriageReturn)) <br />
{<br />
strSerialPortReturnData += Convert.ToChar(inReadchar);<br />
}<br />
<br />
CallMethod(strSerialPortReturnData);
If you want to read All bytes that are there in the buffer use
SPort.ReadExisting()
