I have a problem comverting a hex contain string into Uint32 in VB.net

This is the string:

Dim Address As String = "0xF80F80F0"

and a function:

Private Function StringToHex(ByVal str As String) As UInt32

Dim out As UInt32

If str.StartsWith("0x") Then

str = str.Replace("0x", "&H")

End If

out = Val(str)

Return out

End Function

So when I call the function with the string as input, it causes overflow.

Any idea how to solve this?

Thanks

I stay in university student hostel. We have a refrigerator on each floor where share among us. Few days back I bought some apples and keep in the fridge so that I can eat them when I want, Since from the day I bought them until now I ate four of them and left two, but today I found that the two are gone missing. Is there any way I can stop them from stealing my apple?

Perhaps can give a guide on how to do it? Thanks.

I was about to finish writing the VHDL code for this full adder schematic:

When I wanted to simulate it, I get the following error:

"Parameter C_OUT of mode out can not be associated with a formal port of mode in."

My code: http://www.freewebs.com/alexander3133/addervhdl.tx...

Using Xilinx ISE 9.1i

Any idea what's wrong with the code? Thanks.

If a set of measurements are normally distributed, what percentage of these differ from the mean by more than half of the standard deviation.

I just can not understand the problem and hence I can't solve the problem. Someone can guide me throughout this problem?

Thanks.

I understand that the value of L and T is needed for the tuning, and the value of L and T can be found once the tangent line at inflection point is drawn.

The question is, how would I know where the inflection point is when a transfer function is given.

Thanks

Is it for speaker design?

Or equalizer design?

Or something else?

Why in practice, it never biased this way?

And how this capacitance affects the operation of a p-n juntion in an electronic circuit?

Also explain why the value of the associated capacitance might vary with voltage?

Parallelogram in vector problem?

Point A,B,C and D form a parallelogram in three dimensions, with point A (3,2,5), point B (2,1,3), point C (x,y,z) and point D (4,6,8). |AB| = |CD| and |BC| = |DA|

Find the coordinates of point C.

A coil is wound on an iron former of mean magnetic length of 25cm and cross-section of 4cm^2. The relative magnetic permeability is 1000, leakage, fringing and losses of all types are neglected. The coil will be connected to an AC source of frequency = 400Hz so that the peak current drawn does not exceed 0.1A and the iron operates at a peak flux density of 0.9T.

a) By using Ampere's law, determine the number of turns, N of the coil to meet this specification.

b) By using Faraday's law, obtain an expression relating the peak supply voltage to the peak magnetic field intensity.

c) Calculate the maximum permissible peak supply voltage so that the specified peak current and flux density are no exceeded.
