Hi All,
I am creating a windows app, with MVP architecture.
In presenter, I am adding nodes to the treenode, so in doing so, I am initializing
<pre>TreeNode MainNode = new TreeNode();
MainNode.Name = strProjectFolderPath;
MainNode.Text = strProjectFolderPath;
_view.AddTreeNodes(MainNode);
</pre>
I see the error, when I put a watch on MainNode,
FullPath = 'MainNode.FullPath' threw an exception of type 'System.InvalidOperationException'
Actually I am trying to add items to this main node, so that I get the treeview from the folder.
Please help me in solving this
Thanks
Ramm

Now, why would you want to decrypt files which store user names and passwords?
If you can explain the reason, then perhaps someone will help you.

Hi, Ive made a user control and it works great but the problem is that I dont want it to display on my form when I drag it in from the toolbox. I want it to be like how the timer control works where it doesnt have a gui, as apposed to how a label control works.
Im sure im just not seeing something silly.
Thanks

You need to derive from Component rather than Control or UserControl

hi
Is it correct to leave COM1 open all along the program ?
and close it only in exit from the program ?
thank's in advance
|
|
|
|
|
if you're using it all the time, then yes. If your program is open all the time, but you only use COM1 occasionally, then no.

Sure, you can treat a serial port like a file. If your app needs it, take it. And release it when you are sure you don't need it any longer. If you have multiple open-close cycles, there is a risk the first cycle succeeds, whereas a later one fails because some other app has opened it in the mean time.

Good. You've got the beginnings of a specification there; it needs fleshing out, but it's a decent start. What have you accomplished so far?

here's some pseudocode
repeat
r = get random number
until r is a new unique number
remember you've seen r before
Implementation is left as an exercise to the reader

that may take forever.

An easier way would be to reseed the randomizer after every call with a value greater than the last returned result. It's not a great way, but it cuts out the checking.

When N "random" numbers in [0, RANGE) need to be unique, the range typically is small, so I prefer to put them all in a bag and use a random index to get them, one by one. So there is no need for a retry.
And the problem has no solution for N>RANGE so some precautions need to be taken in any algorithm based on retrying.

You could also shuffle your bag and just pop the top entry each time, depending on where the bottleneck ends up being

That would take a Random Shuffle Generator, which isn't provided by the .NET Framework as of now.

Would that work?
Since the next random value could be less than the seed, you could re-seed with a value you've used previously.

What I was thinking was actually using Random.Next with the starting value being the value you've just retrieved + some small amount as the starting point, e.g. Random.Next(lastVal + 1, lastVal + 100).

I'm afraid there is no way you can tell the RNG what all the numbers are that have already been picked, so the best you can achieve is avoid repeating the previous number, not all the older ones.
Of course if all the OP wants to avoid is consecutive duplication, then your way would be fine.
