C# - Convert System.Windows.Forms.Shortcut Into KeyData / KeyCode?
Nov 15, 2011Is there an easy way to get the corresponding keydata (keycode combination) for some value in that enum? I cannot find one, and creating a switch statement for all those is a bit overkill...The integer values of the enum elements are not keycodes, but some 'unknown' big numbers, so simply casting to int won't work.
View 1 RepliesConvert ASCII To Char?
Feb 15, 2009I have a string of ASCII in HEX. ( 5A65726f)so first i split them into 2s >>>> 5A 65 72 6f then i change the hex to integer using these integer i convert them to char using chr() it did the job great, i can see the correct word i want..but it give me an error saying " make sure it has the right format" ( error shown below)
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim hexnum As String
Dim converttohex As String
Dim hextonum As Integer
[code]....
i thought it was the for loop problem...since i will go up to 7 while len(hexnum) is 8 so it would loop again but there is nothing after 8th HEX?so i tried For i = 1 To Len(hexnum)-1 Step 2 ...this time...textbox didnt show anything...+ the same error came up...

Convert Char To Byte?
Jan 25, 2010My application is reading in data from the serial port. The packet format uses 1 byte to tell the data length. The problem is as I am reading each byte in as a char when I try to get the value of the received character (using Asc(cRxd)) it only works up to values of 127, any bytes received that are over 127 are received as 63. I noticed that this was the default parity replace value, but I have parity.none set and I also changed the parity replace value. The received byte is always 63. I have tried reading the data using .ReadByte but this gives the same result - only works on values below 128.
