Hi,
I need to convert Hex to Decimal for my received data in TextBox1.
Can someone help me in doing this?
The Hex only 2 byte (00 to FF), is there any programming that is easily understand.
Thanks.
Haha.. I found it out by other website..
But i got modify untill very nice woh~ =^__^=
Public
Class Form1Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim HexValue As String
HexValue = TextBox1.Text
MsgBox(Val("&H" + HexValue))
End Sub
End Class
' Although i still don't understand what is &H, ist to convert it to Hex?
' Than how about the "+ HexValue" ?
' Pls answer if you know *smile* it will help alot people
Hope this will help =)
p/s: Feel free please drop by my another thread.. I haven't have the answer ='(
How to program SerialPort1>PortName to take the value(ComPort no.) from ComboBox1?
Thank you.
This does not convert to hex. &H is just what you put in front of a value to tell the compiler that the value shall be interpretated as hexadecimal like e.g. &H16 = 22
I have answered your serial port question, but you could have found the answer yourself in the link I gave you previously!
All input and output on the computer is done as a string. Mathematical processing is done internally. Inside the computer, the value is always in binary. It is converted to decimal for display as a string. The &H simply converts the value to a different kind of string to display so it looks like hexadecimal. The Val() function changes the string display from one kind (hexadecimal) to another (decimal).
Solitaire,
Thanks for ur explaination.. Truly understand =D
Thank you ^^

"All input and output on the computer is done as a string. "
I'm a fan of solitaire and there's not doubt about this but this statement is not correct.
"The &H simply converts the value to a different kind of string to display so it looks like hexadecimal. "
The h is a compile time directive instructing the compiler on how to interpret or display literals.
"The Val() function changes the string display from one kind (hexadecimal) to another (decimal)."
Val does not do anything of the sort.
One thing that NEEDS to be converyed since terminology is ever so loosely applied here.
1.) Everything in a computer is binary.
2.) Sometimes binary is organized into strings, longs, integers and shorts (just to name a few).
Strings are binary with agreed upon standards.
Hex is binary and FORMATTED for the display of base16 values. Hex IS Binary - it is just a way of formatting and displaying binary.
