You can't keep the filenames the same - you are going to have to change them somehow.

The Guid example would be:

string s = System.IO.Path.GetFileName(openFileDialog1.FileName);
string st = "Pict" + Guid.NewGuid().ToString() + ".jpg";
File.Copy(openDialog1.Filename, Path.Combine(@"c:\inetpub\wwwroot\15 website\images", st));

string strQuery = "";
openFileDialog1.ShowDialog();
string s = openFileDialog1.FileName;
textBox6.Text = s;
st2 = s;
string st = "Pict" + Guid.NewGuid().ToString() + ".jpg";
File.Copy(openFileDialog1.FileName, Path.Combine(@"c:\inetpub\wwwroot\15 website\images", st));
strQuery = "INSERT INTO criminal(pic_name) VALUES('"+System.IO.Path.GetFileName(openFileDialog1.FileName)+"')";
SqlCommand com = new SqlCommand(strQuery, conn);
com.ExecuteNonQuery();

PROBLEM:
error comes on this the SQL Query , am i inserting rightly?
or there is some other way
Actually i want to insert only picture name of the picture to be browsed

Depends. Are you using MFC ? the std::string class ? char * buffers to hold strings ?

Handle the KeyPress event and check the pressed key. If it doesn't fit your requirements discard it.

handle the keypress event and write the following code

e.Handled = false;
if (Convert.ToInt16(e.KeyChar) < 48 || Convert.ToInt16(e.KeyChar) > 57)
{
e.Handled = true;
}

Thanks for everyone who replied on my question. I cant get it right do you mean :

protected override void OnKeyPress(KeyPressEventArgs e)
{
e.Handled = false;
if (Convert.ToInt16(e.KeyChar) < 48 || Convert.ToInt16(e.KeyChar) > 57)
{
e.Handled = true;
}
}

I have more than one textbox on that form so how do I check only one?

Thanks again.

Hello,

He meant you should inherit your own NumericTextBox (which has been done about 100 times in the articles)
from Forms.TextBox, and override the OnKeyPress method there.

Or handle the KeyPress event for only the textbox you like to modifie (Like Pete suggested)
yourTextBox.KeyPress+=new KeyPressEventHandler(...);

All the best,

Martin

It's been suggested to you that you should check the KeyPressEventArgs for the OnKeyPress handler. The code would look like this:

private void txtNumber_KeyPress(object sender, KeyPressEventArgs e)
{
  if (!char.IsNumber(e.KeyChar))
    e.Handled = true;
}

This basically uses the IsNumber member of the char type to determine whether or not a number was pressed. If the user types anything other than a number, the Handled value is set to true. This basically tells the system to ignore that keypress.

The code I presented was the event handler for a particular textbox (txtNumber). You would add this code by selecting the textbox in the designer, and then open up the Properties for it. Click the events icon (the one with a little lightning flash on it). And double click the KeyPress item in the property grid. Then you enter the if (...) code inside the auto-generated event handler.

Stream to Icon

Could anyone please tell me how to change the System.IO.Stream to System.Drawing.Icon?

Example ~

<br />
Dim asm As Assembly = Assembly.LoadFile(assemblyFile)<br />
Dim imgStream As Stream<br />
imgStream = asm.GetManifestResourceStream("MyDLL.MyIcon.ICO")<br />
<br />
Me.Icon = imgStream <<< ERROR: Need to convert the stream to icon...

Thanks in advance.

Hello,

The Icon class provides a constructor which takes a stream as param!
See the doku[^]

So in C# example:

Icon MyIcon = new Icon(yourStream);

All the best,

Martin

There is a constructor for Icon class which will accept Stream as parameter.
You should be able to do like this
Me.Icon = new Icon(imgStream);

I reckon the Icon class might have a constructor which takes a stream.

#2. they are watching codeproject forum all the time.. so I got the answer quickly...

I wasn't knocking you - honest!!;) It's good that people vote, and better when the answer voted for is quick, easy and importantly, correct.

I just think it is funny when two people post virtually the same answer to the question. I know it gives you, as the OP, more confidence the answer might be correct, but certain people (they know who they are!) do it just to get their post count up.

<edit>I'm digging a hole for myself now...I am not saying that J@@NS did this for the reasons above - the times are too close together. I think I better shut up whilst I am ahead, or at least not too far behind... Frown | :(
