I'm writing a vb.net program that is going to have a huge number of instances of a particular object and I want to figure out how much memmory each instance of this object is going to use. It has no subs or functions nor any subclasses, just variables and arrays. I know how to calculate the memmory usage of the variables and arrays themselves but I was wondering how to calculate the memmory usage for the behind the scenes elements.
I'm guessing that each variable or array has a 4 byte pointer behind the scenes pointing to it and all these pointers are in an array which would add another 4 bytes. Could somebody tell me if this is correct and if not how should I calculate it?
thanks for your help,
Mike

C# has a sizeof[^] operator that should give you what you want. There is also the Marshal.SizeOf method, but it calculates the size of an object after it's been marshaled to unmanaged code. This size can be different than the managed-code version, which can also be different from a hand-calculated size too.

You'll have to explain this a bit more. Are you talking about printing from an ASP.NET app to a printer on the client side??

Both in Web and windows application, how should I do it. And in web applications server side or even client side. If you can, could you please give me the complete idea or even some code snippet to if possible. Thanks in advance.

In an ASP.NET app, you cannot print to a client-side printer. You can serve up the document and maby some client-side Java can do the printing, but it's impossible to do from your ASP.NET code.

i have a service to run against the database. when it is run on my windows 2000 server platform with 2.0 framework , everything runs smoothly. The problem is when i tried to run the same service in a clients computer, it prompts an error as below:[service cannot be started. the handle is invalid] from what i think , the errors gotta do with the permission for the user. can you guys help me sort this out? or at least give me a couple of possibilities what might have occurred ? thanks in advance.. appreciate any helps given

If you can provide me with more information, I might be able to help...
Is it a smart client app? Or a simple WinForm?
Is the database on the same computer as the client?
Is the database SQL Server 2005? 2000? Access?
I also suggest that you take a look at the exact time when this exception occurs using the debug on a computer with a similar configuration from your client's.

Hi, I've copied a C# server program straight from another computer to my laptop. Im running on Visual Studio 2005 PE version 8.0. Everything compiles okay and installed perfect. The server program have its own install actions to use in the setup project. Now, assuming I did not touch the code and just for fun, I remove the installaction.dll file from the setup project and then add it again back again and adding it back in the custom action....it still compiles perfect. But this time when it installs, it gives me a "Object reference not set to instance of object" error during installation. Then when installation completes and when I run the server, it gives me problems. So anybody have any ideas why it gives me this problem when I just delete and then add back the dll file without altering it whatsoever? Any suggestion or help will be appreciated.
Please note that I have disconnected myself from the VSS.

By removing the file you've probably wiped out some code dependant on it. Just putting the file back won't replace that code. You'll have to see if there's something missing in your project that references that .DLL.

I dont believe any of my code depends installactions.dll file.... I thought the reason it might act like this is maybe because the installactions.dll file was created using an earlier version of .NET and right now Im using the latest version.

If you install .net 1.1, in your laptop, you will not get any such type of errors...
The same is the case for me...why it happens I dont understand, some backward capability is missing in .Net2.0. I guess???

Using ClickOnce? I don't think so. I think you'll have to write your own application that uses the System.Deployment namespace to figure out if various .DLL's in your app need to be updated, downloaded and installed. I have no examples of how to do that. It's never been one of my requirements and I also rarely use ClickOnce.

I don't work for MS, so I have no idea.

It's a nice idea, but I haven't been able to delve into it to see if it supports the distribution model you want it to.
