Hello. I'm a beginner to VB.NET, and i'm sure the solution to my question is easily achieved, however...
I'm trying to have a list of items in a ComboBox. When the user clicks on an item in the combobox, there is a large textbox that I would like a few sentences to appear for each item. How would I go about doing that?
Any help is appreciated ^_^ Thanks.

Hi,
to add items to the combobox just use the items.add method:
combobox.items.add("Item to add")
to change the textbox catch the combobox selectedindex changed (or there maybe a click event as well) and then you have to choices, you can look ad the SelectedIndex property, carrying the index of the selected item or you can look at the Text property with the text of the item. Based on that with some if statements or a select case or even using the selectedindex for accessing an array you can update your textbox.

Hi everybody!!!
I' wrote a function on a Visual Basic 6 application that uses an instance of Excel application (it's a hidden instance and I disabled functions that may slow down such as screen update and calculation), I need to control Excel from this application to do some specific operations. The strange thing is that the same operations i run from from my application to control excel are about 10 times slower than running them from VBA (running the same function as an Excel Macro, saved with the workbook). How is it possible??? Is there something that I missed to check???
Thanks in any case. TK

Let me see the part of your code that you are creating the Excel application and calling some of its operations. You might be accidentally creating a new instance of you Excel app each time you make a call, or, even worse, making multiple instance of Excel. Either way would make your VB app run slow; and, if the latter, increasingly slow.

Hi Quacks!
Yes, you're right, I'm creating an instance of an Excel application each time I call that function but they're closed every time, so there are no multiple instance of Excel running. The machine I use is a bit slow (pentium 3 500MHz) and in fact if i run my application on a faster machine it's quite good but it's still running proportionally slow, I mean if my app runs on a slow machine, the function is done in 1 minute while in VBA in 10 seconds, and if it runs on a faster machine the function is done in 10 seconds while VBA in 1 second. This is what I can't understand.
Thanks anyway!

I am to track what files are being copied out of my PC, whether to a floppy disks, hard disk, network drives or any other USB devices. How do I go about doing it?

You're really going to have a difficult time with this. Since a copy operation is really just opeing a file and reading it's contents, there is no way to tell whe is happening with the data. There are so many ways of copying a file, you can't possibly catch them all.
But, the only way to catch the opening of a file is to write a file system extension. This is NOT an easy task, requiring an in-depth knowledge of NTFS, P/Invoking Win32 API calls, marshalling various structures, ... This is something that higher-level languages, like C# and VB.NET, are not suited for. BTW: The technique I'm refering to is used by FileMon from SysInternals.

I have developed app using MSCOMM32.OCX ver shipped with VB6 ( ver 6.0.8*) when ever we open com port and start accessing data CPU start hitting 100% and FAN start to spin up.
I dont understand why it happen. Is it a bug ? or what wrong with it ?
I dont do any thing fancy.

Pls help!

WShy does this have to mean there is something wrong? If I look at the sysmon, and refresh a page from CP my CPU hits a 100% also.
I would only get worried if something pegs the CPU and keeps it there continuously or for an excessively long time.

Hi everyone,
I need an algorithm/program (code) that can compute planetory position data for a given date/time/place according to Lahiri Ayanamsha (in Indian Astrlogical System). Can anyone please help me to find the same (source code/algorithm) or explain me how to find/calculate it.
Thanks in advanced,
K Amit

First you need to read your horoscoipe every day until it says "Today you will find the answer to that which you seek."
Then on that day, search Google for amateur astronomy sites that explain planetary position calculations.
Should not be hard to find or figure out - after all I did exactly that when I was a 12 year old kid with a telescope. All I used was a pencil, my dad's sliderule, and "The Field Guide to Astronomy".

Would this also work for "simple" satellites like those producing GPS information? I am looking for a position-locator algorithm for GPS satellites provided I know the Date-Time(GPS date-time), the satellites I'm reading on my GPS unit on Earth (names, signal strength), and other info I get from GPS data streams.
Thanks.

Planetary orbits are very stable, otherwise we would have long to live. They are also well defined. So you can calculate their positions at any given time.
GPS satellite orbits are less stable. See the link below for an overview:

Thanks! This looks to be a very informative article. Kepler was a genius!
