password is a reserved field name.
Try changing your code to read:
string qry1 = "update log_in set [password]='" + txtnew.Text.Trim() + "' where userid='" + txtuser.Text + "'";

Thanks for your suggestion
I have used app.config file to store connection string for rest of my application but i am unable to create cyrstal report using that string.
Because when I create crystal report i need to use database field from field explorer which are present only when i establish connection at creation time of crystal report.
Is there any other way to generate crystal report so that i can use app.config connection string for that.

Try something like this:
foreach ([forgot object name] tbl in CRReport.Database.Tables)
{
tbl.SetLogOnInfo("",dbLocation,dbUser,dbPass)
tbl.Location = dbLocation
tbl.SetDataSource(dbLocation)
}
I've not got CR installed here, so can't double check the function and object names,
but I believe that will redirect your database source for you 
The first parameter of "SetLogOnInfo" i think is a connection string, but I don't think you need this when reading from Access.. I've only ever used SQL Server, so I will say this is all just guess work 
Anyways, hope it works for you!

If you let me use your application, I can erase your entire database. Try reading up on SQL injection attacks.

You need to explain exactly what it is you want to do, and what problem you are having. No one is going to just give you code, but we will help you if you get stuck.

Hi!
I am trying to add different values to a combobox in a datagridview.
|TEXTColumn | |TEXTColumn | |TEXTColumn |DataGridViewComboBoxColumn |
|John | |Svensson | |1231421 |Cat |
| | | | | |Dog |
| | | | | |mouse |
|Sarndra | |Larsson | |2344324 |horse |
| | | | | |Bird |
|Adam | |Jönsson | |6587568 |dog |
| | | | | |mouse |
| | | | | |badger |
| | | | | |Tiger |
i set up a data grid view,
private void SetUpforDataGridView()
{
dataGridViewSearched.ColumnCount = 3;
DataGridViewComboBoxColumn dataGridViewcombobox = new DataGridViewComboBoxColumn();
}
And then set the values, it works dine for the textfields but not for the combobox, i get no values in it
public void BindUserList(List<User> userList)
{
object[] row = new object[3];
foreach (User p in userList)
{
row[0] = p.LastName;
row[1] = p.FirstName;
row[2] = p.UserId.ToString();
dataGridViewSearched.Rows.Add(row);
foreach (var unit in p.UnitActivationPeriods)
{
((DataGridViewComboBoxCell)dataGridViewSearched.Rows[dataGridViewSearched.Rows.Count - 1].Cells[5]).Items.Add(unit.ToString());
}
Any thoughts?
