I need to write a new value to the registry. I have come stuck at the following code because what i can add is a standard key and i need to place a new decimal value to a DWORD key (aposed to a hexadecimal value)
{Dim wsh
wsh = CreateObject("WScript.shell")
wsh.regwrite("HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionpoliciesExplorerNoDrivesdword", "789")}
im using vb 2010 and currently working on a program that senses and displays values in hexadecimal, i have already done this part, but now im required to convert the value that is in the textbox, for example 006d to 109.
View 12 RepliesI'm writing a small program that will convert a negative number (e.g. -200) to a hexadecimal number (e.g. FF38). And back to a decimal number. FF38 back to -200. (I can only use two bytes when converting back and forth.)
Question: is there a function in VB that will help?
I currently doing a project..Using VB2005 To convert hexadecimal to decimal. Something to do with serial port..

View 7 RepliesThis program, it reads in a file, and displays it in hexadecimal, like using a hex editor. It then goes to compare the strings and whatnot, and display certain values. During the program, there is a time where I need to display a set of offsets as decimal because that is the way that it is shown regularly.
Taking the two specific offsets and displaying them in hex ends up giving me something like "3039" or "000A", which should respectively convert to 12345 or 00010. This "ID" that I am converting, can be 00000 to 65535, which in hex is 0000 to FFFF. The current method I was given only works if the value is less than 512 or something like that.

I have a DataGridView bound to a DataTable that has 1+16 columns defined as Integer.The default cell style is hexadecimal 2 digits (.Format="X2").When entering in cell editing I would like to provide to the user, the possibility to write the value in decimal or hexdacimal.Hexadecimal could be written like, for example, 0x00, 0X01, x02, XFF
Decimal like 0, 1, 2, 15For this reason in EditingControlShowing I add "0x" to the TextBox value

im having trouble understanding this question for a homework assignment. I need to write the PSEUDOCODE for the following scenario, but i got no idea about how to convert a hexadecimal number to a decimal number..You are required to input a two digit hexadecimal number eg. 3f (digits can be entered separately) and calculate the equivalent decimal number. (note the decimal number will be between 0 and 255) . output the decimal number

View 2 RepliesHow would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01

Is it casting from a double to a decimal implicitly. How would I do this explicitly in vb.net?
1) One Decimal Varibale stores a decimal value
2) The value must be converted in string ( some time the comma is used as decimalplaceholder some time the dot)
3) the user modifies the value
4) i need to riconvert the string back in decimal
how can i do this
so:
Variable 123.34D ----> textBox 123,34 or 123.34 -----> variable 123.34D
I have 4 radiobuttons hex dec oct bin all the buttons works perfectly except the Hex.When i calculate or press a number in decimal, and i check the Hex, the number will perfectly change into hexadecimal, but when i try to calculate within Hex, its a calculation in Decimal.So i repeat.. i can calculate in base 8 octal, base 2 decimal, and base 10 decimal, but i cant calculate in base 16... and i think it has something to do with the letter notation...

View 4 RepliesI am trying to display the register contents in a textbox in hexadecimal. I would like to always display 4 characters. The register is 16 bits wide. I have 4 byte parameter variables (param_a_1 through param_a_4) for containing the incoming register value. Because of the way the packet is communicated into the VB app, I pick out the bytes I want displayed and convert them to a string for displaying. The values I get in are not always converted correctly
View 1 RepliesSearching this forum and google turn up things which seem too complicated(more then 4 lines of code), but maybe it needs to be that way.I have two text boxes. A 1 byte hexidecimal value would be entered in to each of them (0-FF). How can I add those two values together to come up with an integer?I have tried this several ways. At one point I got it to work but only for numeric characters.

View 13 RepliesWhat's the trailing ampersand on VB hexadecimal numbers for? I've read it forces conversion to an Int32 on the chance VB wants to try and store as an Int16. That makes sense to me. But the part I didn't get from the blurb was to always use the trailing ampersand for bitmasks, flags, enums, etc. Apparantly, it has something to do with overriding VB's fetish for using signed numbers for things internally, which can lead to weird results in comparisons.
So to get easy points, what are the rules for VB.Net hexadecimal numbers, with and without the trailing ampersand? Please include the specific usage in the case of bitmasks/flags and such, and how one would also use it to force signed vs. unsigned.
