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;                              
  }
}

Is this[^] what you looking?

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;  

}

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.

access asp.net website from an ip address ?

Read the PIG. You build an 0100 message, to identify the card (block 3) and pin (14). An 0110 response from the card system will let you know if the card should be retained or not; the ATM protocol just relies on the server telling it to retain card or not. I can't remember the blocks, but you have to check both the return code and the message.

Hope this helps.
