string chunk_split ( string body [, int chunklen [, string end]] )
This functoin can be used to split a string into smaller chunks which is useful for e.g. converting base64_encode() output to match RFC 2045 semantics. It inserts end (defaults to "\r\n") every chunklen characters (defaults to 76). It returns the new string leaving the original string untouched.

What is the problem? From the description its pretty clear what it does, so just implement the same in C#. One way is to use a StringBuilder and inject '\r\n' at every 76 char interval.

Hi,
thanks for your reply. As I am new in C#, would you please show me the snippet for doing this. !!

Thanks and regards

Minimizing a Windows Form to the taskbar programmatically?

Re: Minimizing a Windows Form to the taskbar programmatically?

I have a windows form application. When the user clicks the pause button, I want to programmatically minimize the window. Does anyone have the snippet for doing this in the 2.0 Framework?

Thanks

Thanks leppie, but I cannot find WindowState in either my instance form or the static Form methods. The closest thing I can find is form.ReflectMessage, but I don't know exactly what the hWnd message would be to do a minimize.

System.Windows.Forms.Form.WindowState : FormWindowState straight from Reflector.NET

leppie, I don't doubt you, but in C# Express the Intellisense Forms.Form stops at ReferenceEquals and does not show WindowState at all.

Its an instance property Smile | :)

Unless C# Express is broken or it has changed in .NET 2, it has to be there! Wink | ;)

I'm not finding it in the instance object either. It is .NE 2 but it is also C# Express which at least limits some of the functionality of the framework. Though I cannot see why they would hide the WindowState property.

datetime format in c# and asp.net

Whew, that did it. Never thought to go into the form code and type this.

Thanks leppie.

Hi
I am programming in c#.net. I want to insert i record into the SQL Server database. the datetime format in SQL server is mm/dd/yyyy where as in c# its dd/mm/yyyy. therefore when i try to insert dates where the day value is greater then 12 it gives out of range error.

Is there anyway we can change the format (dd/mm/yyyy to mm/dd/yyyy) of the datetime as we insert it into the sql server database.

Use parameterizes queries, then the date format is not a problem.

If you need to format the date as a string, I suggest that you use the ISO 8601 date format, e.g. yyyy-mm-dd. It's an unambigous date format, so the database can not misinterpret it.

I think you can pass the format via the ToString method.
If all else fails: see my

It's not the best according to readers, but it works Smile | :)

hi i draw a rectangle in picterebox and i want to rotate it around it's center and i want enable doublebuffering for prevent flicker and get highest quality
for my animation but it doesn't work

the ather problem is when i call g.Dispose(); in timer1_Tick event my app is crash .where does my problem and how to animate my rectangle with
doublebuffering and highest quality without flicker my animation ???
my code here :

Graphics g;
Pen m_pen;
Matrix mat;
int angle;
bool _doBuffer;

public Form1()
{
InitializeComponent();
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.DoubleBuffer ,true);
this.UpdateStyles();
m_pen = new Pen(Color.Violet,3);
bm = new Bitmap(src);
mat = new Matrix();
angle = 1;
_doBuffer = true;
}

private void button1_Click(object sender, System.EventArgs e)
{
g = pictureBox1.CreateGraphics();
g.DrawImage(bm,20,20,100,100);
timer1.Enabled = true;
timer1.Start();
Invalidate();
}
private Bitmap _backBuffer;
private void timer1_Tick(object sender, System.EventArgs e)
{
if(_backBuffer==null)
{
_backBuffer=new Bitmap(pictureBox1.ClientSize.Width,this.ClientSize.Height);
}
Graphics g=null;
if(_doBuffer)
g=Graphics.FromImage(_backBuffer);
else
g=pictureBox1.CreateGraphics();
g.Clear(Color.White);
g.SmoothingMode = SmoothingMode.AntiAlias;
p = new Point(70,70);
mat.RotateAt(angle,p);
g.Transform = mat;
g.DrawImage(bm,10,10,100,100);
//g.Dispose();
g.DrawImageUnscaled(_backBuffer,10,10,100,100);
Invalidate();
}

You approach is wrong. Only handle painting in the OnPaint event, you can however do the rest where you have them now.
