Hi, I would like know if something libraries or programs exist, and send
error with a description if the program don't find the libraries, how can
make that?.
For example:
In the use of interop libraries of Office, I declare that libraries in the
begin of code:
Imports Microsoft.Offic e.Interop
But when the user don't have that libraries, the program don't run
(inmediate crash, they don't start), and the user never know the failure
point.
Thanks in advance for any help.

I believe if you use ClickOnce deployment you can set prerequisites
that must be installed with the application. If they do not exist (and
can't be downloaded) a more descriptive error message will be shown to
the user.
Also, I don't believe the program should crash until it tries to
reference the missing library. If that's true, you should be able to
use a simple try...catch block to handle the errors and display a more
helpful error message.
Thanks,

Seth, How put external programs like prerequisites with ClickOnce?. The Try
cath, only work inside class, I have global variables, exist a way to put
external Try Catch?.
For example, I have this code:
'--------------------
Imports EARTHLib
Public Class FC_Form
Dim camara As New CameraInfoGE
Dim GEarth As New EARTHLib.Applic ationGE
Private Sub FC_Form_Load(By Val sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
End Sub
'---------------------
In the code I'm using Google Earth, but if the user don't have the
application, the program crash, the program don't start.
Thanks in advance for your help.

To be honest, I've only used ClickOnce prerequisites for Microsoft
products like Office and Sql Server, and never any third party
libraries. You best bet is to search Google or MSDN and try to find
some instructions. Armin has already shown you how to properly
instantiate the "unstable" code, so you might not need to worry about
the prereq's if it does what you require.

It's been a while since I've done programming in C. What I'm after is a

two questions:

Could a "header-library" exist?
2) Why do libraries have extensions .a and .so and

Hi all,
I want to know why do we use libraries(static or shared).
We can perform that work by including header files too.I also wish to

i know these are pretty easy and basic questions.
But plz help me considering the fact that i am a new developer

Thanking you in advance.
