Regardless of application type you can pass variables through constructor parameters, method parameters or properties.

Good grief no! That is extremely bad practice.

That's not being spoiled, that's picking up bad habits... Which I suppose happens if you get spoiled also..

Yeah you can. It's generally not a good idea, but you can.

It is possible, but I don't care to explain as it is very heavy to run on the server and you are probably better of building a true web application.

There's a property for the CheckBox class that makes it appear like a button. In combination with setting Checked to true during startup that's exactly what you want.

Well, HTML is essentially XML, and neither are really compiled in the traditional sense. What do you want as your output?

What does this have to do with C#? Are you trying to do it through a C# app? If yo are, take a look at the MS Office Interop...

actually, I want to implement this by using POI, but it throws exception. So I would like to know whether I can do this by using MS PIA and C#. Is it feasible to do this ?

What are those?

I generally do all of my MS Office/C# using the Office Interop. I think you can do the protection of the workbook this way, too.

Hi Paul,

For MS PIA, I refer to Microsoft Primary Interop Assemblies.

Can I do something like select "Tools->Protection->Protect workbook" from the menu in Microsoft Excel by using Office Interop ?

Please give me some hints and help. Thanks in advanced.

Excel.Worksheet has a Protect method. I am not 100% sure if this is it, but you may want to look at it.

Maybe as a macro or something. I'll give it some thought Big Grin | :-D
