I have been trying to create a setup project for an application. I am having trouble with one aspect however. I simply want the installer to execute another small program I wrote during installation. This other program applies some additional settings. I placed this executable under the custom actions tab in the "install" folder. I expect this to run once during installation, but I instead find that it runs every time I double-click on the newly installed applications shortcut. Why in the world would this custom action execute every time the new program is run? And where is the exe for this custom action being stored since its not in the installation directory?
Thanks.

Hello!
I have a problem with creating these arrays. The MAXNumberOfVectors and the MAXNumberOfVertices get the error to be used as a type name instead.
How do I do this, because this won't compile as it is, and I don't have a clue as to why this is... I am sure there must be a slightly different way to do this in C#. But that I couldn't find in my books how to do this.
Please some advice...
Thanks,
Ranger.
public class Storage
{
public int CenterX = 150;
public int CenterY = 150;
public int NumberOfVectors = 0;
public int NumberOfVertices = 0;
public const int MAXNumberOfVectors = 100; <-- compile time error
public const int MAXNumberOfVertices = 200; <-- compile time error
public Vector[] StoreVectors = new Vector[MAXNumberOfVectors];
public int[] StoreVerticesFrom = new int[MAXNumberOfVertices];
public int[] StoreVerticesTo = new int[MAXNumberOfVertices];
public Point2D[] StorePoints = new Point2D[MAXNumberOfVectors];

Well, I looked around in articles on this site, and found a reference to a method that creates an instance for an array, where you can determine yourself what the size and type of this array is. So I tried the following way to get to declare an arry of a certain size.
Still I get the following error message and that I don't know what this message means.
Can anyone help me clear this last hurdle..?
Thanks,
Ranger....
Static member 'Aljo3D_1.Storage.MAXNumberOfVectors' cannot be accessed with an instance reference; qualify it with a type name instead
private const int MAXNumberOfVectors = 100;
private const int MAXNumberOfVertices = 200;
public Vector[] StoreVectors;
public int[] StoreVerticesFrom;
public int[] StoreVerticesTo;
public Point2D[] StorePoints;
public Storage()
{
Array StoreVectors = Array.CreateInstance(typeof(Vector), MAXNumberOfVectors);
Array StoreVerticesFrom = Array.CreateInstance(typeof(int), MAXNumberOfVertices);
Array StoreVerticesTo = Array.CreateInstance(typeof(int), MAXNumberOfVertices);
Array StorePoints = Array.CreateInstance(typeof(Point2D), MAXNumberOfVectors);
}

This works... I removed the word 'const' from the MAXNumber variables and now it compiles without errors.
I knew it was something simple.
Ranger. 
public int MAXNumberOfVectors = 100;
public int MAXNumberOfVertices = 200;
public Vector[] StoreVectors;
public int[] StoreVerticesFrom;
public int[] StoreVerticesTo;
public Point2D[] StorePoints;
public Storage()
{
Array StoreVectors = Array.CreateInstance(typeof(Vector), MAXNumberOfVectors);
Array StoreVerticesFrom = Array.CreateInstance(typeof(int), MAXNumberOfVertices);
Array StoreVerticesTo = Array.CreateInstance(typeof(int), MAXNumberOfVertices);
Array StorePoints = Array.CreateInstance(typeof(Point2D), MAXNumberOfVectors);
}

Use a List instead, unless you really want to have a maximum possible number.

Hi,
your code compiles just fine for me. This is what I have:
public class Storage {
public int CenterX = 150;
public int CenterY = 150;
public int NumberOfVectors = 0;
public int NumberOfVertices = 0;
public const int MAXNumberOfVectors = 100;
public const int MAXNumberOfVertices = 200;
public int[] StoreVerticesFrom = new int[MAXNumberOfVertices];
public int[] StoreVerticesTo = new int[MAXNumberOfVertices];
}
So I dont know what went wrong for you. Also I suggest you mention the exact
compiler message (instead of "wont compile" or "does not work" or so).
And there is nothing wrong in using the const keyword to indicate something will
never allow to be modified, it is considered good practice.
BTW I concur with Christian's remark to use some (unlimited) collection instead;
you seldom need to impose a maximum (you might want to do that when memory becomes
tight and can be better spent, or when simulating a fixed size cache, or so).

Well, I got an error message which disappeared after some trial and error changes to my code.

I read about that in a book about C# I bought, but I am a novice, so I plan not to bite off more than I can chew, because I found that <list> matter kind of complicated.
As it is I am amazed about what you can do with Microsoft Visual C# 2005 Express Edition.
With programming practice, I am getting more understanding of how to use classes to keep things relatively easy to understand as you program gets to be able to do more and more.
I am having a ball with Express Edition.
Thanks for your comment.

Hi guys,
We have users in our company running one of the applications that I developed and unfortunately at the moment any code change I make, I am having to reinstall the whole application. Is there a way to create an update project that will search a particular dll and update it with the new dll without having to reinstall the whole app.
Please help!!!!!

If you're using .NET 2 take a look at the ClickOnce[^] technology

|

unfortunately I use 1.1

There is a Microsoft Application Update block I think which might work under .NET 1.1, alternatively there are a couple of articles
here on CP which deal with the issue. Basically what you have to do is write a small program which checks for the update from a url or something (looks at an xml file for example to see if the dll versions have changed) and then download these. If there are no updates or there were you then run the program regardless, exactly like a bootstrapper.

If you want to implement anything resembling a complete Firewall you need to look at the Packet Filtering API from Microsoft. Be warned though that this is not an easy API to work with, especially from managed code.
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer

Hi
I want to capture audio in my program and transfer it through the internet to the same program that will play the sound.
Is there a component in the .net that I can use for that. Or I have to use Windows API?
Can I use the DirectShow lib 1.5 for that and get all the functionality that I'll need?
Is there an article or a code example on that.
thanks in advance

Search for DShowNET that might do what you want, basically a port of DirectShow to .NET.
