I have a user-defined control which has as a child control a TextBox (.NET 3.0). When I call Focus() on this TextBox, it doesn't work. However, if I add a MessageBox.Show() line, and then call Focus(), it does indeed Focus on the TextBox. I'm not sure what is happening here - focusing on a different control, and then on the TextBox, doesn't seem to produce the same effect. Can anybody point out my (probably obvious) mistake?

Try to call Focus() on the user control first. Where did you add the MessageBox.Show() line?

The code is like this:
<br />
LineControl newLineControl = GetControlForLine(newLine);<br />
MessageBox.Show("try now"); <br />
newLineControl.Dialogue.Focus();
I tried adding newLineControl.Focus() before newLineControl.Dialogue.Focus() as suggested, but it didn't make a difference.
I tried logging when each control gets and loses focus, and got the following result when clicking on a LineControl (my user control):
TextBox got focus
LineControl got focus
..then away from it:
TextBox lost focus
LineControl lost focus
This was the same regardless of whether the MessageBox.Show() line was included, yet when that line is included, newLineControl.Dialogue.Focus() works, and when it isn't, it doesn't. Any ideas? Very confused.

What part do you not have any idea with? Is it the datagridview part or the Excel Office Interop part ( I am assuming this is how you are going to do it )?

You are not very clear. If you want to run another .exe from an .exe, you can use the Process class.

Well, you...
1. take the input that the user has given you.
2. hash the password (because you are using hashed passwords, right?)
3. call a stored procedure that looks up the user and compares the hashed passwords. This will return a true/false back to to the application.
4. If the password is correct you allow them to continue
5. If the password is wrong you repeat the process or exit the application.
If you want more detail on any of this you have to show where you got stuck. If you take a different design descision you have to tell us what that is.

I was going to say salted hash, but I figured one-step-at-a-time would be better here.

Oh yes, just in moderation. Then maybe eventually some retna scanners and thumbprint scanners, too ( but that might be overkill  )

I suspect that some people think that salted hash refers to seasoning their food.

Hi everyone,
I have a data bound ComboBox control on my form which is initialized as follows:
Database db = Database.Instance;<br />
m_accountsList.DataSource = db.Students.Tables[0];<br />
m_accountsList.DisplayMember = "Name"; <br />
m_accountsList.ValueMember = "ID";
The dataset is edited down the line to insert a new row as follows:
<br />
OleDbDataAdapter adapter = db.CreateAdapterForTable("Students_T");<br />
OleDbCommandBuilder cb = new OleDbCommandBuilder(adapter);<br />
DataRow row = db.Students.Tables[0].NewRow(); <br />
row["Name"] = m_Name.Text.Trim();<br />
db.Students.Tables[0].Rows.Add(row); <br />
adapter.Update(db.Students.GetChanges());<br />
db.Students.AcceptChanges(); <br />
I see my ComboBox get updated as soon as the second code block is executed. However, selecting the newly inserted entry results in an error as the returned SelectedValue property is null (It is supposed to return the ID) of the newly inserted row.
Has anyone else noticed the same thing? Any suggestions on how to fix this would be extremely appreciated.
Thanks,
Keith
