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:

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"));

Problem with TcpClient connect [modified]

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. Big Grin | :-D

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'; //Specify end char of your byte stream<br />
 string strSerialPortReturnData="";<br />
 int inReadchar;<br />
 while ((inReadchar = SPort.ReadChar()) != Convert.ToInt16chCarriageReturn)) <br />
                         // read the return data<br />
            {<br />
                strSerialPortReturnData += Convert.ToChar(inReadchar);<br />
            }<br />
<br />
CallMethod(strSerialPortReturnData); //Call the method with read string<br />

If you want to read All bytes that are there in the buffer use
SPort.ReadExisting()

System Tray Icon with background processes [modified]

synunn4-Jul-06 23:40

Hi kids

Background

I'm writing a system service style application. It consists of a NotifyIcon in the sys'tray that has several functions that are called from the ContextMenu/Events.

When the app' starts it should do nothing but sit there until the 'Start Sending' MenuItem's Event is called. This event starts a new Thread which checks a file repository between Thread.Sleep(15*60*1000).

Problem

To cut to the chase, the application is maxing out the cpu usage during a loop:

while(this.Created){<br />
    Application.DoEvents();}

How to I prevent this excesive usage?

Do I need to access the System Idle Process?

This usage doesn't actually halt the server or even slow it down it just capitalizes the usage as there is no other contender for the cpu's attention. I have tried to drop the Thread.Priority to BelowNormal but the applications Thread remains at Normal in Task Manager.

Just make it sleep between the times it handles the messages:

while (this.Created) {<br />
   Application.DoEvents();<br />
   Thread.Sleep(100);<br />
}

b { font-weight: normal; }

I thought that too but it causes a crash, The problem is that Events don't stack up between each Sleep so you have to click during the split second that Application.DoEvents(); is running OMG | :OMG:

Not to worry though, I found a solution

Yes, the messages are queued.

If the program crashes, there is something else that causes that.

Check for all installed .net frameworks

How do i get information about all installed .net framework version? And On what framework my application is running?

Say I have application config file saying
<startup>
<supportedRuntime version="v1.0.3705" />
<supportedRuntime version="v1.1.4322" />
<supportedRuntime version="v2.0.50727" />
</startup>

So It will run on all the platform. Now, I want to check on which version its running and what all versions are installed on the system.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
