Convert 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...
VB Express Conversion From ASCII Char To Hex
Jun 23, 2009I read in a unique file type, its called .pkm, it's just a collection of hex data. Anyways, I'm using VB Express 2005 (or 2008 since it's free), and I read in the file, and printed out the values. It printed out the ASCII character equivalent, so all I saw were the weird symbols and all (the hex characters in this file do not convert using ASCII). What I want to do is convert it to hex so I can see what the hex values are.
Code:
Dim file As String
Dim data1 As String
file = "D:Documents and SettingsownerDesktopPokemon7-10-08_10ANNIV_ENG_Lugia.pkm"
[Code].....
Too bad image code is off. That is a screen from a hex editor that reads it in properly. Currently my program displays it the way it is seen on the right, but I need it displayed the way it is on the left, in plain hex.

Determining If A File Is Text/ASCII Char Only?
Jan 26, 2012Simple question, what would be the optimum code in VB2010 to read in a text file and verify that:1) It is a text file, and2) There are no non-ASCII characters anywhereAnd conversely, we would want the code to provide a warning if the file is not a text file, or if the text file contains non-ASCII characters. [Note that LF, CR and EOF are expected to be in the text file, and should not be flagged as errors]
View 1 RepliesUsing Split Method - Error: Char Values Cannot Be Converted To Integers
Feb 10, 2009i have a form with 12 text boxes. I'm trying to get the data from those text boxes to "save", and when that form is opened again have the data be inserted back. This form has different time slots so I need to be able to have it save and repopulate based on what time slot I am clicking on. I was going to have it read the data by splitting it with commas, then inserting them back into the correct fields but it's not working. I had it write the results to a text file and they get written correctly and inserted back, but the problem with that is it only reads that text file so every time slot I open up gets the same data. Below is code I used to get the data when the Save button is clicked. [Code]
Problem is I get an error saying "Char values cannot be converted to Integers" on the first line, the (","c) part. Plus even then I don't know if this would do what I want. EDIT: Ok I fixed the error and got it kind of working, but now I have a new question. Now, I put a button on the form that I can use to load the data when I choose to just to test. This works, it takes the data from each time slot and loads it back when I click the button. New question is how can I get it to load as soon as I open the existing appointment? Putting it in the form load event won't work because it checks for data before there is any in there.

Forms :: Get The Key Char On Key Down Event Of Textbox?
Mar 23, 2009On the KeyDown event of the textbox, i need to capture the character pressed and send it to a function which fires a sql query for this character.To get the character i am using Convert.ToChar(e.keycode).However Convert.Tochar converts the keycode to char according to its ASCII value , thus F4 gets converted to "s" as "s" has ASCII keycode of 115.Is there some other way to convert the keycode to character which won't make these wrong conversions as even if i restrict the functions keys there may be problem with other key conversion also.
View 2 RepliesForms :: Program To Show Ascii Code Used?
May 8, 2011but I am trying out VB.net and is trying to make a program to show the ascii code for every key press I made.. here is the coding i used..
Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As _ System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
TextBox2.Text = e.KeyValue
End Sub
this one seems to work fine, but I noticed that regardless of whether I use "A" or "a", the ascii code shown is always 65. last i checked small letters have their own ascii code, so "a" should show a ascii of 97, not 65..

View 1 RepliesAsp.net - Character Support - Translate Higher ASCII Characters To Lower ASCII Characters?
Aug 7, 2009So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?

View 2 RepliesForms :: Listbox Faster Method For Selecting All
Dec 1, 2010I have a listbox control that has a selection mode "MultiSimple" (I've also tried MultiExtended). I also have a button that uses this code to select all the items in the list:
Dim i As Integer
For i = 0 To ListBox1.Items.Count - 1
ListBox1.SetSelected(i, True)
Next i
It works ok but the problem is that it's very slow. I have cases where there are 60 000 items in the listbox, and it takes forever to select them all. Is there any function that would select all at once (Just like ListBox1.ClearSelected() unselects all instantly)?
