An array is 0 based. So if the array contains 500 elements the first has index 0 and the last 499. In your for cycle (with <=) at the end you were trying to access to the element with index 500 that obviously is outside the bounds of the array.

Just run the CREATE DATABASE query

and then create your tables

Hope this helps.

there is this thing called a book... In it they have examples and tell you how to do things. Plus if you want to make life hard for yourself with out using enterprise manager you should be able to do this yourself!

Simple question about controls

Hello gurus,

I have a simple question for C# masters concerning controls.

I have a series of label with a formated name.

In a loop, I want to recover a pointer on the control (a label) by giving its name as a string.

for example:

<br />
Label lbl = null;<br />
string lblName = "";<br />
<br />
for (int i=0; i<5; i++)<br />
{<br />
  lblName = "lblL" + i.ToString(); // lblName will contain "lblL0", "lblL1" etc.<br />
<br />
  // here is what I'm looking for...<br />
  lbl = ???; // the label is supposed to point on the label with the built name contained in the variable lblName.<br />
<br />
<br />
  // now the lbl variable points on the right control with name given by the variable lblName<br />
  lbl.Text = i.ToString();<br />
}<br />
<br />

How to make the control pointing to the right one given its name?

I hope you understood my question in my poor english.

Best regards.

Fred.

Hi Fred,

Would the following solve your problem:

lbl = new Label();
lbl = (Label)FindControl("lblName");

Yes, that's it, in a recursive way and for WinForms.

Sorry, my mistake. How about something like this:

Control myControl = new Control();
foreach (Control c in this.Controls)
{
  if (c.Name == "lblName")
  {
    myControl = c;                              
  }
}

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

Something like that but for WinForms...

The is no FindContol method in WinForm. You can implenet your own

for this to work the control names need to be unique.

public static Control FindControl(string controlName)
{
 if (!controlName.Empty)
     return this.Controls.Find(controlName, true)[0];
 
 return null;  

}

ATM program in consol application

you dont need to loop the controls, you can simple access it like an array and specify the control name, i.e.

Label lbl = (Label)Form1.Controls[lblName];

If I undestood well:

just create a variable, and increment it whenever the user fails to insert acc and pass. Once it reachs the times you set as limit (3) dont allow the user to log anymore.

Hope this helps.
