Someplace in your code you either have using keys or in the code you have keys.
You need to provide a reference to the dll that the keys namespace / object exists.
Go to references right click and add a reference.
Or remove the code that has keys in it if it is not needed.

Remember that C# is case-sensitive. You have to write Keys if you're referring to the framework's built-in class.

Hi,
I have already made this but i just cant do it again!! I'm missing something.....
What do i need to do in order to have a ok button to close a form?
What i have done was:
- Create a button in a form and give it a name (btnOk)
- Go to form properties and select btnOk in AcceptButton property
What do i need to do more?
Thx,
Nuno

Do you open the form using ShowDialog?

Add an EventHandler for this button click event and call
this.Close();
in that method.
Cheers,

Create a button.
Double click it in the sub section (function that appears), type this
this.Close();

Hi,
Visual studio is saying that it doesnt know the method close.
You know, i'm thinkinhg this is very strange since i have already done something which i only had to tell in the mainform who was the accept button, and now i can't do it for this case.
Thx,
Nuno

I have a wacom graphics tablet / pen pad. Is there a way to capture the signature with c#? Thanks.
|
|
|
|
|
There's always a way, but how it's done should be covered in the SDK for the pad. There's nothing in the .NET BCL that's going to "do it for you". I have no idea how it's going to be done, but it would depend on how the PC talks to the pad, be it Serial Port or network or USB.

 I was thinking it was something like a credit card signature pad! :->

I have been developing for a while now, mostly in VB. But now I have seen the light and joined the C# parade.
Anywho, is there a difference between the functions and use of string. functions and String. functions? I use .Empty, .IsNullOrEmpty, and .Format all the time. Does it really matter if I use string. or String.? I know that one is a type, but besides the color in VS, what is the difference, and should I use one or the other?

string is a C# keyword that is an alias to System.String.
If you have "using System;" in your file and you don't have any other class named String, then String (the class) and string (the C# keyword) are equivalent. Otherwise String may refer to your own String class, while string always refers to the built-in string class.
Another difference: you may use String as a name for local variables (if you like to confuse people reading your code), but string is reserved.
But normally using string or String makes no difference, both compile to the same IL.

I've always been told to always use the lower case as it makes it easier to read on others who are viewing your code (unless they come from jave)! Also, you should learn all about string builders. They are the best item for creating multi component strings and they only are created once, not every time you add another string element.
Sorry for the diatribe.

I would not recommend writing your own String class; too confusing !
|

There really isn't any difference. string is the C# alias for System.String, which is the actual CLR data type.
I personally use string when declaring variables and String when calling functions (like .Empty, .IsNullOrEmpty, and .Format) as I think it makes it a little clearer; but that is simply personal preference and string.Format is exactly the same as String.Format.

String may refer to your own class, string refers to the inbuilt string class

Hi Guys -
I am having problems dragging and dropping controls on my forms in VS2005. Nothing is locked and I am able to move them if I go into the properties window and manually change their position...but it won't allow me to grab them and move them around 
|
|
|
|
|
This is just a guess, but is your app running. If you app is running I think it locks the from even through you can still see it.

Hi.
When the new webbrowser in .NETCF 2.0 is loading, a progress bar is displayed at the base of the control.
Does anyone know how to stop this from appearing?
I'm only using the control as a HTML viewer, so I really don't want to see the progress bar everytime I send new information to the page.
Thanks.

Hi
I have an ActiveX control which behaves well outside of the .NET environment. However when i used it via interop i can't seem to set the backcolor and forecolor properties.
Anyone any ideas?
Cheers
|

|
|
AX controls don't always respond to .NET standards, such as having Fore and Back colors. This is probably settable only if the Ax control provides some means of of setting those explicitly outside the normal properties.
