Can I safely assume that if I write a small program in C# that uses SQL Express for its database, that it will run nicely on a pentium III 1.0 GHz with 128 - 256 MB of memory? Or is it wiser to use MS Access instead?
Because all programs I created up until today using C# or .NET in general run on at least a P4 machine with 256 MB memory, which is indeed considerably faster

It's wiser to add a ton more memory.

That can be arranged, but the machine has to go for another year

You just have to maintain awareness of what you're doing when you use SQL Express. Besides missing Enterprise Manager (but you can get freebies on the net that does most of it) it is basically a fully implemented engine with built-in size limitations on tables. And SQL Server 2005 will suck up every ounce of memory you provide it and then drool if you wave additional memory cards over your machine. So if you handle memory cards around your machine....were shark gloves if you want to keep your fingers.

I am trying to build a small application that collects data about several client applications; it also listens for triggered events and represents them graphically.
I have a basic version running ok. I am storing the client info directly into a listview. However I would now like to do other 'clever' things with the collected client info. I was planning to store the data in an array.
The problem I have run into is that I do not know the size the array will need to be until I have started to populate it with data. Is there a way to dynamically add data to an array? Or is there another way of storing the client info (so it can be processed and have things done to it)?
Thanks in advance...

Take a look at the System.Collections and System.Collections.Generic namespaces.

In .NET 1.1 try ArrayList. In .NET 2.0 try List<t>.

Why don't you use a System.Collections.ArrayList or a System.Collections.Generic.List<t> ?

Ahh now this sound like my kind of tool. I planned on writing something similar once to graphically map transactions as they moved through BizTalk.
When you use an ArrayList or List<> the structure is such that an initial size is created and dynamically grows as you add additional items. It is better in the performance department if you generally know how many items will go into the array, but it is not a necessity.
You can also deploy custom dictionaries as well so you may want to do something like this:
Applications go into a List<icommunicators> (all the applications inherit the same interface making it easy to store different programs but treat them as the same type)
Application fires a trigger event
Listener (your code) plots that event but also adds to a Dictionary<string, eventlist="">
ReceivedEventEventHandler(object sender, ListenerEventArgs e)
{
ICommunicator details = (ICommunicator)sender;
PlotEvent(details.Name, e.EventObject);
dictionary[details.Name].Add(e);
}
Now you can expose a menu selection to show historical event data for any program in the list, trending across applications, frequency of events across time, and other fun statistical stuff.

hi,

Explore the System.IO.Compression namespace.
This page[^] has an example for reading zip files.

Pls tel me is that way should i compile using .Net platform?,or different way?
|

Yes you have to compile it that way.
But you can use a IDE such as Visual C# Express which is free (search Microsoft's webpage). You only press F5 there and everything is done for you.

You sound a little lost at sea. Download VC2005 Express. You will still have an error, most likely, but the IDE will tell you what it is. I have no idea what your comment on namespaces means, all C# code has namespaces.

Im using vs.net 2003.pls tel me if i want display message like "Hello World",hw can i do it in vc#.net 2003.

If you have VS2003, why on earth are you compiling on the command line ? Create a new project in the IDE, and press F5 to compile and run it. As I said, you'll probably get the same error, but more meaningful info on what you're doing wrong.
And if you're at the 'how do I make 'hello world'' stage, I strongly recommend buying a book and working through it.

Hi all.
I have a picture box that stretches over my entire form, as I use the an image for the background of the form. On top of the form I have labels, I need to set the back color of the labels to transparent, when I do this via the properties of the label it makes the backcolor of the label gray, I asume it is because that is the color of the form, but i need it to so the image through the label.
What must I do?
Is there some way that I can copy the image of the picturebox at the location of the label and then set that as the backcolor for the label??
Any help will be much appreciated
Thanx in advance
