Yes, I know that. Read my previous post again, and you might realise that.

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?

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

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

Thanks in advance

hi,
In my windows application i added a menu strip item. The default color of the menu strip is the colors of the windows xp (blue and white).
When i change the backgroung color property to the color i want it is changed.
but when i click on an item for example File the menu that pops down under it has the color of the original menu strip (blue and white). I need it to be as the color i set. I couldn't find any property for that.
Is there a way to do it?

This code works for me.
MenuStrip mainmenu;
ToolStripMenuItem File;
ToolStripMenuItem News;
ToolStripMenuItem Exit;
mainmenu = new MenuStrip();
File = new ToolStripMenuItem();
News = new ToolStripMenuItem();
Exit = new ToolStripMenuItem();
mainmenu.BackColor = Color.Red;
mainmenu.ForeColor = Color.Yellow;
File.BackColor = Color.Violet;
File.ForeColor = Color.Cyan;
News.BackColor = Color.DarkBlue;
News.ForeColor = Color.DarkGreen;
Exit.BackColor = Color.DarkViolet;
Exit.ForeColor = Color.DeepPink;
File.Text = "File";
News.Text = "News";
Exit.Text = "Exit";
File.DropDownItems.Add(News);
File.DropDownItems.Add(Exit);
mainmenu.Items.Add(File);
this.Controls.Add(mainmenu);
