If you use any CLS-compliant language you'll need the .NET redistributable on the target machine. An alternative is to use something like Macromedia Director or Macromedia Flash (make a standalone exe). You could also use the now obsolete VB6 (and hope that they have the VB runtime DLLs)
The safest approach would be to use HTML pages (you can then have gifs, jpgs, swf etc in sub directories)

You'd be surprised if I tell you the number of projects done at present day using VB6.

But for windows client applications which needs to go into desktops of the masses, I guess people would still prefer using the RAD tools of the past.
I dont think its justified to download a 20mb runtime for a program that has a couple of dialogs. Probably thats one of the reasons we havent seen some cool products (something popular like winzip or a messenger).

Ok here is the scenario. I have an automated process manager that I am running, it is polling using the timer class every 10 minutes to see if something needs to be run.
If the window is FormWindowState.Normal the memory is between 11 - 21 meg which is fine, when I minimize the window it drops memory useage to around 600k, which is great.
However if I try to run GC after a poll and successful process run, the memory doesn't seem to get collected no matter what I try. I would expect memory to realease to at least 3 - 4 meg once the process is completed however when I call GC this doesnt happen, if I manually minimize the display the memory releases down to 600 - 800k. So I dont think I have references in place that should be there, its almost like GC doesnt fire until I minimize.
Any thoughts?

One other quick question is there an event that fires when FormWindowState property is changed? I cant find one in documentation but wanted to make sure I wasnt overlooking anything.

well you cant really force the GC to run your just asking it to.
implement the dispose method on those references and set them to null so you can force the release.
make sure no other object holds a reference to it or it will not release. Much like the old com refernece counter.

Hello !
is there an efficient way to trim a byte[] to a new size?
i need this for a socket.receive:
byte[] data = new byte[1024]; //Input-Buffer
int recv = s.ReceiveFrom(data,ref sender);
i tried this:
byte[] trimmedData = new byte[recv];
for (int i = 0;i

The best way to do this is to use a vector<byte> and then you can just use resize().

your going to need to use the wininet.dll to control internetconnect and few other functions from that library

Here's my class...
using System;
using System.Windows.Forms;
namespace GPG__
{
public class logging
{
LOG logForm=new LOG();
aOut caller=new aOut();
Form1 guiForm=new Form1();
int k;
public logging(string [] aLog, string start, string end, string duration, int delay, string file)
{
logForm.Show();
logForm.listBoxLog.Items.Add(DateTime.Now.ToString("hh:mm:ss")+": Processing: "+file);
<big> if(guiForm.checkBoxEnableDelay.Checked==true)
{
MessageBox.Show("CHECKED");
logForm.listBoxLog.Items.Add(DateTime.Now.ToString("hh:mm:ss")+": Delay "+delay.ToString());
}
else
{
MessageBox.Show("NOT CHECKED");
}</big>
for (k=1; k<aLog.Length; k++)
logForm.listBoxLog.Items.Add(DateTime.Now.ToString("hh:mm:ss")+": ["+aLog[k].ToString()+"]");
}
}
}
Now, look at the if statment asking if checkBoxEnableDelay is checked...
When ever I run this, it always evaluates to false, and the else stament runs... and yes, the box IS checked...
If I put the same code on my main FORM it runs fine...
WHat is the problem?
p.s. (ignore the broken for statment at the bottom... it's not like that in my code..._)

hmm... I think it has somthing to do with if the check box is checked at form load, or not...
cause if I set the checkbox to checked in the PROPERTY EXPLORER, the if statment elvaluates to true. But if I un check it in the RUNNING FORM, it still evaluates to true...
and it's the same vice versa... if I uncheck it in the PROPERTY EXPLORER, it will elvauate to false, even if I CHECK it in the running FORM...
any ideas?

it's because you are declaring a " new " instance of Form1

why not add the checkbox to the logging sub, eg:
public logging(string [] aLog, string start, string end, string duration, int delay, string file,CheckBox cb)<br />
if(cb.Checked==true)<br />

Thanks for taking time to respond to my question. I'm going over a threading sample from MSDN and is having a hard time trying to understand the sample:
(a) Monitor.Wait
(b) Monitor.Pulse
(c) waiting Vs ready queue in context of threading
(d) Why you need to add a "readerFlag" in the resource you are acquiring a lock on when you have already locked the resource using "lock( )" statement.
Before going further, reference to MSDN here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/vcwlkthreadingtutorial.asp
QUESTION 1:
"A lot of times there are a couple of steps to locking an object"
>> Q1-a: I don't get it. To lock and unlock an object:
Monitor.Enter(thisObj); //This won't return until you get the lock
thisObj.DoSomething();
Monitor.Exit(thisObj);
To try to lock and obj, use Monitor.TryEnter instead. But, in our MSDN sample:
public void WriteToCell(int n)
{
lock(this) // Enter synchronization block: The "lock()" block.
{
if (readerFlag)
{ // Why do you need this flag if you have already "lock" the resource???
}
} // Q1-b: Lock release here - my understanding correct?? This means you can do whatever you want in the "lock" block.? (Exiting THE "lock()"-block)
}
}
>> Q1-c: Once you acquire the lock (via Monitor.Enter or lock() function as in sample), NO other thread can acquire lock on "thisObj" until "Monitor.Exit". There's NO need for "readerFlag".
QUESTION 2:
Quote:
"Now that the cook is done, you go "hey over there, it's my turn! No one else is allowed to cut in front of me!" so you call
[
Monitor.Wait(this);
]"
>> Q2-a: Doesn't Wait function surrender lock to resource to next thread in "waiting queue". According to MSDN, Wait() does this:
* "Releases the lock on an object in order to permit other threads (in waiting queue) to lock and access the object."
* "Releases the lock on an object and blocks the current thread until it reacquires the lock."
My question is, why release lock BEFORE you actually do something (Read) with reseource?
public int ReadFromCell( )
{
lock(this) // Enter synchronization block: The "lock()"-block
{
if (!readerFlag) //WhY?? You ALREADY have the lock on "this" resource.
{
try
{
// Again, WHY!? You ALREADY have lock on "this" resource.
Monitor.Wait(this);
}
... catch statements...
}
Console.WriteLine("Consume: {0}",cellContents); //Q2-b: NOW you're reading - but why can't you read immediately after "lock(this)" statement???
readerFlag = false; // Q2-c: I have no idea why we need this flag.
// is done.
Monitor.Pulse(this); // Q2-d: I have no idea why we need to pulse - exitining the "lock()" block surrender the lock, other threads waiting for the resources will naturally be able to acquire it once execution exit the "lock()" block, why Pulse???
} // Exit synchronization block: The "lock()"-block
return cellContents;
}
>> Q2-f: waiting queue Vs ready queue - What the... It's in Monitor class documentation (.NET framework).
Help!
