When I press F10 and then up or down arrow key there appear a box with options Restore, Move, Size, Minimize, Maximize and Close. I think that comes from system, because many windows has similar box (like properties on desktop).

Problem solved, thanks to Hans Passant.

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == Keys.F10) return true;
return base.ProcessCmdKey(ref msg, keyData);
}

Hi! Here's the problem:
I have an exe (no source code) wish for it to run only when it finds a valid license on the pc. Therefore I wish to modify it somehow (wrap,modify, etc) so that it will check for certain criterii such as hardware id before launching itself.

What I've found out so far:
I know I can create another exe that embeds the exe using Visual Studio. However, running the exe from memory only applies to .Net exe. I wish to cover non .Net too. And I know that running non .Net exe from memory is very hard.

Question:
How do i do this? Is there a way to modify the exe so that I can insert checking codes before the exe launches normally?
Thanks!

linkbuttons lnkBTN = (linkbuttons)this.findcontrol("linkbutton"+i.ToString());
lnkBTN.Text = "anything";

i am getting an exception saying object reference is not found i created an object for that linkbutton using new keyword

Hello,

I prevere the 'as' operator for casting, as it will never throw an exception!

linkbutton actbutton = controlfound as linkbutton;
if(actbutton!=null)
{
    actbutton.SpecialProperty = "wrtferc";
}

If you only whant to access a member of control and just whant to know if it's typof, there would be no need for the casting.

if(controlfound is linkbutton)
{
    controlfound.Text = "hnvkjhfdjkv";
}

All the best,

Martin

Hello,

Like somebody said befor, what is FindControl doing? (please show code)

But apard from that:

kalyan_2416 wrote:
(LinkButton)this.FindControl

This will throw an exception if the control which is returned from the method, is not typof LinkButton.
Therefor I suggested the 'as' operator.

LinkButton l = this.FindControl("blabla") as LinkButton;
if(l!=null)
{
     //it's a linbutton
}
else
{
   //it's not a linkbutton
}

All the best,

Martin

ContentPlaceHolder cMainContent = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1");
for (int k = 0; k < outlet_arr.Length; k++)

//l.Text = "kalyan";
LinkButton l = (LinkButton)cMainContent.FindControl("LinkButton"+j.ToString()) as LinkButton;
