hi have one siple problem if you have time pleas tell me how to solve it
so i have printer name in one dropdownlist

best regards
thank's lot

First check that you have written the code to populate the printer name ddl inside
if (!Page.IsPostBack)
{
}
block
Secondly you have to put the code to populate the printer model ddl in the SelectedIndexChanged method

Hi,
I would like to add a record in the last row of a database from a c# program. I have a database with the first column called ID which is unique. I tried doing this by finding the maximum number in that column and then adding 1 to it but it doesn' work.
Thanks
|
|
|
|
|
Standard questions
1) What database?
2) "doesnt work" - what doesnt work and what error if any
3) show your code.
|
|

|

I have a database with some questions and each question has a unique ID.
In my c# program I have a form with a datagrid showing all these questions and 2 textboxes, 1 showing the id of the question (txtQstID) and the other showing the question (txtQst).
Then I have a button (btnAdd) that when I clicks it a new question is added in the datagrid. The new question is entered by the user in the txtQst textbox. But the ID of the question textbox is readonly so the user cannot enter anything in it.
So I did the following in the add button: -
//getting the maximum ID from the Qst_ID column
System.Data.OleDb.OleDbCommand oCommandMax = new System.Data.OleDb.OleDbCommand("SELECT MAX(Qst_ID) FROM Questions", conn);
object objMax = oCommandMax.ExecuteScalar();
string maxValue = objMax.ToString();
//parsing the maxValue to integer
int newRecord = (int.Parse(maxValue));
//adding 1 to the maximum number
newRecord++;
//displaying the new ID in the txtQstID textbox
this.txtQstID.Text = (newRecord.ToString());
//CreateNewQuestion is a method found in Class 1
Class1.CreateNewQuestion(txtQstID.Text, txtQst.Text);
//The following is the code found in Class1: -
public static void CreateNewQuestion(string ID, string Question)
{
DataRow drNew = DS.Tables["Questions"].NewRow();
drNew["Question_ID"] = ID;
drNew["Question"] = Question;
DS.Tables["Questions"].Rows.Add(drNew);
}

See Guffa's response below...the key in the database should generate itself - generating that key by adding 1 to the highest number will be errorprone.

.
.
.
System.Data.OleDb.OleDbCommand oCommandMax = new System.Data.OleDb.OleDbCommand("SELECT top1 * FROM Questions order by Question_ID desc", conn);
.
.
.
//insetead newRecord++; increase by one
int newRecord = (int.Parse(maxValue)+1);
|
|
|
|
|
And then what happens when 2 users execute this code simultaneously?
|
|
|
|
|
One of them will get an error message because they try to create a record with the same key.

Correct, next question for 10 points 
|
|
|
|
|
Set the id field to be a counter/identifier/auto_increment (depending on the flavour of database you are using). Then you just add a record without specifying the id at all, and it automatically gets a new unique id, without any risks of conflicts.

How do you determine if a value of a comboxbox was changed by being clicked on? I have set databinding on the combobox and the values in it change when i scroll a datagrid.
Please help

This might help, but since you don't give enough information it might not help: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetsec/html/SecNetHT02.asp[^]

Can anyone tell me how do I count the number of seconds elapsed after a certain piece of C# code is executed?
|
|
|
|
|
I would create something to hold a start time. And then when I need to know the number of elapsed seconds I'd get the current time and calculate the difference.
