Vivek is probably gonna make a password grabber and put it onto a machine in the pentagon. He will then proceed to take over the world and it will be all your fault. Thanks Martin# Hmmm | :|

ASP.NET C# strange string array problem!

Hello everyone,

I have an ASP.NET C# website that loads data (modules). This is my code below:

private void prevMod()
{
string[] stModArray = (string[])Session["modArray"];

for (int i=stModArray.Length-1; i>0; i--)
{
if (Session["selectedModule"].ToString() == stModArray[i].ToString())
{
Session["selectedModule"] = stModArray[i-1].ToString();
break;
}
}
BindData();
}

Ultimately, this button loads all the data into a string array and when you press it it moves to the previous item in the array but before I'm able to do that I get this error:

Object reference not set to an instance of an object. - for (int i=stModArray.Length-1; i>0; i--)

Does anyone have any ideas? Thanks in advance I appreciate the help

Have you tried stepping through the code to see what causes the error ? Is modArray always a string array ? Are the strings ever null ?

Michael101 wrote:
stModArray[i].ToString(

This is kind of ridiculous, you call ToString on a string, and it could be null, which would cause your error.

What causes the error is when I try to return the length for the for loop. I know the ToString looks stupid I origionally didn't do that but I will check if a null value is getting passed in but I can't see why...... The problem is when it firstly initiates the for loop.

Then stModArray must be null. Have you tried setting a break point to see why it fails ?

Yep I've found the problem.... It is null after all..... I did a Response.Write command and it's empty. I heard there is a way of promoting people within the site, since you've helped me I'll be more than happy to do it for you. How do you do it though?

Thanks for the help

That brings back some memories.... this dude would write code like someString.ToLower().ToString() and someString = someOtherString.ToString(). WTF | :WTF:

Which service is it that you need to control and by control do you mean start and stop? Most services can be started and stopped by running the command

net stop [servicename] or net start [servicename]

It is possible. If I remember correctly you wanted to do it over a network. Just add a handle to a Timers tick event(you can make it tick every second). Make the tick call a method that tries to accept a client and reads from the stream. If there was a connection just run the following code:

System.Diagnostics.Process pro = new System.Diagnostics.Process();
pro.StartInfo.FileName = "net";
pro.StartInfo.Arguments = "start messenger"; //replace messenger with your process name
pro.StartInfo.UseShellExecute = false;
pro.StartInfo.CreateNoWindow = true;
pro.StartInfo.RedirectStandardOutput = true;
pro.Start();

can anyone explain clearly whether C#.net is platform independent or not? so many people saying their own style. still i am confused. TIA

C# is plateform independent because it's virtual machine concept.
matter of fact is this .Net Applications can be run on any plateform that supports the Virtual Machine (.Net FrameWork like JRE for Java)

Even with java this is not completely true. Applicatiosn always use OS functions. The OS functions mey contain bugs and quircks that makes it just a little more complicated. I know about horrible cases where two diferent applications require non-compatible runtime engines. So platform independency is always relative. The least you should do is test on each platform.

The answer is not simple. C# is an independantly standardised language, but rigt now, it works in the .NET framework, for Windows, and under Mono ( in Linux ), but I'm not sure how complete the Mono implimentation is.

We can deploy vs.net c# application on mono framework in linux. But it is quite hard I can deploy some simple c# windows application in linux with mono.
