try this:
for(//some condition)
{
linkbuttons lnkBTN = (linkbuttons)this.findcontrol("linkbutton"+i.ToString());
lnkBTN.Text = "anything";
}

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

You don't need the additional casting "(LinkButton)".
And you should make the !=null check like I said before!

LinkButton l = cMainContent.FindControl("LinkButton"+j.ToString()) as LinkButton; 
if(l!=null)
{
    l.Text = outlet_arr[k].ToString();
    j++;
}

To use Outlook and Word you need to use the MS Office Interop capabilities. These give direct access to the functionality of Office apps from your .Net application. Here[^] and here[^] are some MSDN articles that show you how to use them.

wceusbsh.sys problem

Hi,

We are selling Handheld Terminals in the company where I work.
The Handheld terminals are using Microsoft ActiveSync to communicate using USB.

But we have some problems, that first time we connect the Handheld Terminal (Which is a Datalogic barcode reader with Windows CE 5.0), Windows XP can not find the driver wceusbsh.sys, and therefor we need to "force" it to use the driver from the ActiveSync directory\drivers.

When we have forced it to use the driver from the directory we can connect the handheld terminal in the same USB port without any problems.

Is it possible to develop some kind of program that can tell the Operating System (XP,Win2k etc)
that it has to use that driver, because we have a lot of costumers asking about what we can do about it. And Datalogic can not do anything (They say).

Hope someone has an idea to solve this problem

Rewriting progress code in C#

Hello All,
I have a chunk of code which needs to be re written in to C#.
The challenge is I want to port this code blindly.

Is there any utility/ tool which can automate the process of doing this or I have to port this code the hard and real way, I mean understanding the progress code and then rewriting it to C#.

Please suggest.
Thanks and regards.
Amar.

It really depends on the language your chunk of code is written: for instance, if it is (already) C# then the Identity transformation will do the job in automatic and safe way!

Pallini,

Thanks for your reply.
I did not understand your comments, request you to elobrate.

To give you more information.
1. I have a code written in Progress 4GL it is live and is a business application.
2. I have to write this code again in C# means porting the complete application in to .Net.
3. I wish to achieve this without unerstanding the code and it's logic.

What I interpret from your reply is ,

Identity transformation can do this job of writing a progress.w file into cshart.cpp file?

Please comment.
Thanks and Regards.
Amar.

My answer was just a joke.
IMHO you have to understand code logic and craft the C# implementation (at least, you'll gain knowledge of the business logic...), anyway check if the Progress Software Corporation has the right instrument to perform automatically the job (good luck).
