I just did that on the last form, to cause this form to appear so that doesn't seem the right thing to do.
Michael's suggestion has worked use - this.Height = 276;
Thanks

public frmNewPerson () {
InitializeComponent ();
Form.ActiveForm.Height=276;
}
would work, but it doesn't, it says...
Message="Object reference not set to an instance of an object."
and highlights the line Form....
So am I just putting this line of code in the wrong place or what?
As you are in the constructor of the form, the ActiveForm property hasn't been initialised yet.
Try
this.Height = 276;

Put it in the Form's Load event instead of constructor.
private void frmNewPerson_Load(object sender, EventArgs e)
{
this.Height = 276;
}

That's what I thought, but I had tried ( as suggested by engsrini ) that I try it in the Load event, but it still failed. But thanks this.Height works.

Hi .
Need to Convert base64 string representing header of the binary field with image data.
//ds.Tables[6].Rows[1].ItemArray[2].ToString() contains base64string
{
Byte[] byt = Convert.FromBase64String(ds.Tables[6].Rows[1].ItemArray[2].ToString());
SaveToOut("image/jpeg", byt, true);
PerformScaleImage(contentType, content, Response, 150, 50);
MemoryStream stream = new MemoryStream();
stream.Write(buff, 0, buff.Length);
using (Bitmap img = new Bitmap(stream))/*---Giving invalid parameter exception-------*/
{
--------------------------}
}
Can you give details.

The error comes because you haven't reset the memory stream before reading it.
You should create a read-only memory stream from the array instead:
MemoryStream stream = new MemoryStream(buff, false);
Now the memory stream contains the data from the start, and you can read from it right away.

The error is at the line pointing to ------(A)
MemoryStream stream = new MemoryStream();
stream.Write(buff, 0, buff.Length);
------(A)
using (Bitmap img = new Bitmap(stream))/*---Giving invalid parameter exception-------*/
{
--------------------------}
}

Yes, I know that. Read my previous post again, and you might realise that.
---
Year happy = new Year(2007);
|
|
|
|
|
MemoryStream stream = new MemoryStream(buff, false);
After that also its giving same one
Invalid parameter for bitmap constructor.
|
|
|
|
|
I have tested it, and as expected it works just fine.
Where do you create the array buff, and what does it contain?

Year happy = new Year(2007);

Hi friends,
how to validate textbox should accept only numeric in c#.Net. Please Help.
Thanks in Advance,
Regards,
Prya

You can override the OnKeyPress or OnValidating methods of the TextBox, if overriding the KeyPress then simply filter out the keystrokes which are not numeric. If overriding the OnValidating method then you can use int.TryParse to check to see if it's a valid integer.
There are numerous articles on the web about how to do this, the best solution in my opinion would be to override the OnKeyPress event.
I have no idea what I just said but my intentions were sincere.

That will work if the user didn't use the paste feature
|
|
|
|

Hadn't thought of that  , suppose it'll have to be either the OnValidating or OnTextChanged.

to complete with a bit of code, what has been already so nicely said:
void TxtRegisteringKeyKeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
char[] myNum = new char[11] { '0' , '1', '2', '3', '4', '5', '6', '7', '8', '9', '\b' };
bool blnNumFnd = false;
foreach (char c in myNum)
{
if (e.KeyChar == c)
blnNumFnd = true;
}
if (!blnNumFnd)
e.KeyChar = '\0';
}

Use MaskedTextBox Instead of Normal textbox, where you can restrict user entries
