How do I make textbox (or label) to have a value, who
is increment for 1, every time when I put some
data in database?
For exaplme, textbox had a value=1!
When I press button, ex: Insert data,
the data are inserted in database, and
textbox then, should have a value 2!
Like a sequence number, I need for
inserting data in database, but I don't user
to enter this, number, instead, the number to
increment it self, when I press button, ex: Insert data,
and, value of that textbox to go in database...
Thank you!

You have a counter somewhere. In your button handler for the insert you increment the counter and update the Text property of the TextBox.

just keep your textbox's enabled property = false...
and in the click function of the button
write this
private void button1_Click(object sender, EventArgs e)
{
int i = int.Parse(textBox1.Text) + 1;
textBox1.Text = i.ToString();
}

Well - first of all, the database must support an autoincrement. Then, you need to get this value back. If it's SQL Server, then you are in luck because you can use the Scope_Identity in the same command to retrieve the value just inserted. Ideally, you would do this in a stored procedure. For instance:
CREATE PROCEDURE [dbo].[SaveData]
@ID INT OUT,
@Name NVARCHAR(50)
AS
SET NOCOUNT ON
INSERT INTO MyTable (Name) VALUES (@Name)
SET @ID = Scope_Identity() To retrieve the information, you would use a SQL Command and add the @ID and @Name parameters yourself. The OutputDirection of @ID would be InputOutput, which allows you to retrieve the incremented value from @ID.

From a windows application form I need to print a ticket from a special ticket printer. that ticket includes a 2D barcode which is a string of all the information about a customer. I need to encrypt it and get as a byte array so I use Cryptoservices and done that. to concatenate that data with other data I've done something like this
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
string str = System.Text.Encoding.ASCII.GetString(b);
So printing part is working fine. But when I scan the barcode and try to get it back to byte array like this,
byte[] b = System.Text.Encoding.ASCII.GetBytes(data);
Then my array size gets smaller and when I try to decrypt it it throws an error saying that invalid length of string.
can anybody help me.

You can't use ASCII encoding to get the bytes as a string. It only support seven bit character codes, which means that any byte that is between 128 and 255 is replaced by a question mark.
Actually, you shouldn't use any text encoding at all to turn arbitrary bytes into text. Most encodings does't have a character for every possible byte value. Text encodings are used to turn text into bytes and back, not the other way around.
You have to encode the bytes in a different way. You can for example use base64 encoding:
string str = Convert.ToBase64String(b);<br />
<br />
byte[] b = Convert.FromBase64String(str);

when I use base64 its working fine. But i want to optimise the space taken by the barcode. I tried hex conversion and that also works fine. and then the size of the barcode is smaller. I want to make it much smaller.

Base64 puts 6 bits of data in each character, which only gives an overhead of 33%. That's the most compact way that you can easily represent binary data as text.
Hexadeximal representation only puts 4 bits of data in each character, giving an overhead of 50%.
Even if you find some complicated conversion that can squeeze almost 8 bits of data in each character, that is only about 30% better than base64. If you want to make the string substantially shorter, look at what the data represents and see if you can remove any unused parts of it.

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

If you get the solution can you please post it on all the forums your posted this question.

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

Hi there I have a textbox and want only numeric values to be entered because the value eneterd into the textbox will be written to my database. Thank you

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