am developing application in ASP.Net with C#. i am using button for FileOpenDialog to browse any image from hard drive as follows
openFileDialog1.ShowDialog();
string s = openFileDialog1.FileName;
textBox6.Text = s;

problem is:
i want the browsed image to be copied in local hosti.e,""C:\\Inetpub\\wwwroot\\15 WebSite\\images\\1.jpg"

i have the follwing idea in mind
File.Copy("C:\\Inetpub\\wwwroot\\15 WebSite\\images\\1.jpg", "C:\\Inetpub\\wwwroot\\15 WebSite\\images\\xyz.jpg");

or
File.Copy(s.Substring(13,s.Length-13), "C:\\Inetpub\\wwwroot\\15 WebSite\\images\\xyz.jpg");
but i dont want to existing image to be overwrite, i want all images to ve saved in local host
can anyone sugesst me what to do?

If you use File.Copy("C:\\Inetpub\\wwwroot\\15 WebSite\\images\\1.jpg", "C:\\Inetpub\\wwwroot\\15 WebSite\\images\\xyz.jpg");
it will throw IOException if the destination already exists so you should check that before you start copying. What so you want to do if the file already exists? I suggest you give them all unique name using GUID.

will u plz make ur sugesstion some more clear that "give them all unique name using GUID" GUID?

He means that the Guid type is guaranteed to generate a unique value, so there is no danger of overwriting files. For instance:

string fileDest = Path.Combine(@"c:\Images\Copy", Guid.NewGuid().ToString() + ".gif");
File.Copy(@"c:\Images\MyImage.gif", fileDest);

can u suggest a solution for following problem
public static int count = 0;
private void button3_Click_1(object sender, EventArgs e)
{
openFileDialog1.ShowDialog();
string s = openFileDialog1.FileName;

textBox6.Text = s;
string st = "Pict" + (count++) + ".jpg";
File.Copy(s.Substring(13, s.Length - 13), "C:\\Inetpub\\wwwroot\\15 WebSite\\images\\" + st);}

i want the image to be saved in local host with the same name as as it was present in hard drive (from where it was browsed)

i have applied ur GUID example but unfortunately its not working, can u apply this in my code?

Use the File.Exists method to check for the presence of a particular file.

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
can u plz suggest any solution

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

Pete O'Hanlon20-Sep-07 0:02

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.

Thanks again for replying. I still cant get it right this is the code I used I dont know what to do so I just tried this can you help me again please.

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

where must public class NumericTextBox : TextBox be inserted?

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.

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.
