hello!i'm designing a software using vb .net that works with an antenna receiver to plot the radiation pattern received by the antenna. the software will read the signal/data sent by the receiver and plotting it.
Q1.so, how do i interface the software and the hardware?
Q2.how to save the data in obtained in a file?
Q3.after saved, the software is then display a numerical value based on the radiation pattern obtained?i mean, from the data obtained and saved we show a certain value..
thank you

Well, the parallel port is the obvious choice, although I think .NET 2.0 has support for the serial port, for the parallel, you need an external dll.
Q2 is trivial, once you have data, you save it any way you like. Same with Q3

I am trying to monitor the processes running on my system. i don't know how i can retreive the CPU use for each process. Just for ease of application, i am adding them the CPU Usage stats to a listbox.
So it would be lstCPU.items.add('here is where i have the problem')

Look into the system.Diagnostics.Process class. I think it's got what you need. You can get a list of running processes and a bunch of information about them.

Correct, this is what i'm working with, yet there is no member in system.diagnostics.process that pertains to process usage that i am aware of. Anything more specific or how do i go about using performance counters.

Hi all.
I have found a really weird problem, and have given up trying to find how to answer this. MSDN and the windows forms programming book just don't explain this:
I have build a type converter that implements saving complex types through the InstanceDescriptor.
The class works without a problem generating code for the design mode until you run the program. Once run, the type converter is broken. It cannot convert and I get that darned stupid cryptic message "cannot convert [type a] to [type a]"
does anyone have any thoughts or suggestions on what is happening here?
Thanks,
Tom

I messed around with a quick post i saw and found out that using casting in the type converters may cause crashes. I removed all of the casting and am now pulling the values from the object.
I also seem to be having trouble if i inherit from typeconverter, but have no problems from expandableobjectconverter
It works, but I'm really uncomfortable not being able to check a type prior to using it in the program. (granted it's only at design time) but still, I want to be able to do this.
Thanks.

Is it possible within vb.net2005 to specify where a messagebox will be placed on screen, e.g. x=, 7= ???
|

By default, a MessageBox is displayed in the center of the screen, and you can't change it's location. But, you could always create your own MessageBox via a Windows Form.
Trinity: Neo... nobody has ever done this before.

I have a subroutine that creates new pictureboxes when a user clicks a button. Here is a condensed version:
ReDim Preserve Picbox(array_size)
For index As Integer = 0 To array_size
Picbox(index) = New PictureBox
Next
For index As Integer = 0 To array_size
Me.Controls.Add(Picbox(index))
Picbox(index).Image = blip
Next
Now, I need to know how to be able to remove a picturebox, or otherwise manipulate the new pictureboxes. When I modify/erase pictures in the array, nothing happens to the pictureboxes on the form. How can I manipulate these new pictureboxes?

If you want to remove a specific picturebox according to your code, use dispose method as shown below.
Picbox(index).dispose
I think that should work! 
What a curious mind needs to discover knowledge is noting else than a pin-hole.

That does not work. The pictureboxes remain on the form.
|
|
|
|
|
Try Me.Controls.remove(Picturebox name goes here)...

i have 1 labels, 1 text box and one check box
suppose label contains name,
in textbox user have to enter its age
and checkbox is checkd if he is married.
i have given conneection string using oledb in access sheet
and its storing the values of label, textbox and checkbox succesfully
but nw i have problem when i have many number of labels , correspondin textboxes and checkboxes.
when i enter all the values i want them to get store on one button click in my acccess sheet.
m uanble to implement any logic.
can smbody help..

You can iterate over your controls collection and find these different controls. Otherwise, you need to write the code to deal with them, one by one.

i think both not gonna work...
if i go for iteration
then i need to run the loops , i also thought abt same logic
but while writing into connection string u cant write label'i'.
it has to be no. only.
and i cant deal them individually
suppose i have to store for 200 hundred people..
i cant write code for individual case....
its nt feasable man....

There are no other options, sorry. How does a control Id go into a connection string ?

common man there mst be some logic...
any other logic u suggest..

You're right. There's a way to do this, and I'm keeping it a secret from you.
OR, if you have 200 labels and you want to data bind them, then you need to write the code to do it yourself, or come up with a solution that involves iterating over the controls collection. If you answered my question, I may be able to help more. How is a connection string going to take a control Id ?

If I understand what you're doing, you should not be using a bunch of labels, textboxs, and checkbox's. Your approach requires you to write lots more code than is necessary. This problem is more appropriately handled by a bound DataGridView.

Hi Again,
How do I get it so that when the caret is on a normal line the formatting buttons are false, if I place it on a bold piece of text the Bold button is true etc like word does?

What control are you using ?

Sorry, always forget to mention that

No, what control are you using, that shows bold text and has a caret. Is it the rich text box ?
