Convert Char To ASCII
I was wondering if there was a way to check that the first character in a string is a letter vs. a number.
Example: "123M" vs. "M123"
I was thinking of taking the first charcter, changing it to its ASCII value and comparing it with ASCII value of letters vs. numbers to figure it out that way..
Is there some feature in VB 6.0 that i can use to see whether the character is a letter or number? (Zero is included in the numbers.)
Thanks!!
Getting A Char From It's ASCII Code
Hi
I'm writing a function to create random strings and I do something like
string = string + Chr(random_ascii_value)
It works to some extent but not exactely as I expect it to.
It only generates upper chars and simbols like : ; > =
The random_ascii_vaule is in fact at least 97 (ASCII code for 'a') and at most 97 + 24 ('z' I think).
Does this has to do with 2 bytes strings (unicode?) or what?
So how can I generate the plain char for a ASCII value if CHR doesn't do that?
Thanks

Code Page Problem For The Char Where ASCII > 127
Just a very simple code:
Code:
Dim sStr as String
sStr = Chr(150)
debug.Print ASC(sStr)
When running the above code in egnlish windows, it can return 150, but When running it in Double-Bytes Windows Environment (such as Traditional Chinese), it will return 0.
I have tried ASCB(sStr) but the result is same.
Anyone know how to solve this case?
Convert Hex To ASCII, Code Is Attached
Arnout, I don't see CLng() returns a Decimal value from Hex. I tried as follows but a mismatch error happens. It only takes values 0 to 9
Option Explicit
Dim SMSOctetOutput
Dim StrHextoDecimal, StrDecimalToAscii
Dim strText
Private Sub Command1_Click()
SMSOutput = Text1.Text
StrHextoDecimal = CLng(SMSOctetOutput)
StrDecimalToAscii = Str(StrHextoDecimal)
Text2.Text = StrDecimalToAscii
End Sub
My intention is to convert a Hex value to ASCII
Convert ASCII Code To Character
I am able to get the ASCII code for a character by using the Asc function, but how do I go about getting the character for that ASCII code? If there a command that is pretty much the opposite of Asc?

Ascii <-> Char
Hi...Can anyone tell me how to convert a character to an ascii value and vice-versa?
Ascii Char
Hello,
I made a program for read ascii characters from modem with win 98 2 ed. and VB6, It were working fine, but now I change to winxp and I can't see the ascii characters and I need these characters for controll the program.
I mean I started to read the string with char(13) and separate between fields with "," and end of the string with vbcrfl, but If I can't see the ascii character, I can´t read the string:
the string is CR,field1, field2,...,fieldn,CRLF.
Someone told me that I need to change the mscomm.ocx for mscomm32.ocx, I put it but nothig change I still can't see the ascii charcaters.
As matter of fact I read ||OK||AT121345678||..... with win98, and
I read with win xp ⌂⌂OK⌂⌂AT12345678⌂⌂
Any advices
Thank you in advance

Unicode Char To Extended ASCII
i not sure whether i using the right header.
however i came across a website that is able to display some words that i believe to be arabic characters using "ãäÊíÈáíãÈáÊájhgjsfáÈÓÔí" using only a normal label..
i believe the same can be done with chinese characters.
but with the chinese characters, how do i do the reverse to achieve characters such as "ãäÊíÈ"
Thanks,
Single Ascii Char To File
I'm trying to add a single byte to a file of chr(175). It's a control character to another program.
I use the following code
Dim chrStart As System.Char
Dim chrEnd As System.Char
chrStart = Chr(175) ' ascii af
chrEnd = Chr(174) 'ascii ae
Dim sr As StreamWriter = File.AppendText(ConfigurationSettings.AppSettings("RootDirectory") & "xf" & Session("Agency") & ".sst")
sr.WriteLine(chrStart & "5H-SPECIAL SERVICE TRANSACTIONS" & "{ENTER}" & chrEnd)
sr.close
When I look at it in a hex editor I get c2 af and c2 ae.
I'm assuming the c2 is a unicode thing but I can't figure out how to get rid of it. I just want the af and ae written to the file.
Any ideas????

How To Display The Char Whose ASCII Value Ranges From 1 To 31?
Dear all,
I am working on a VB program which allows the user to type in any chars whose ASCII values range from 1 to 255. But, it seems the TextBox or Rich Text Box that VB carries can NOT display some of the chars with ASCII values ranging from 1 to 31. For example, ATL+1 can not display the SOH char in the text box. But, I do have a program in hand whose text box can display SOH as a smilling face. I don't know what operation is taken behind the scene. Is there a way for my VB program to display those chars with ASCII value 1 to 31? Please advise and thanks in advance...

How To Return The Ascii Value (int) For Each Char In A String (harder Than It Sounds)
ive got unicode in a textbox (forms 2.0 control)
ive got 2 characters in there
Text2 = ChrW$(27489) & ChrW(36814) 'says welcome in chinese
but using the code
For x = 1 To Len(Text2.Text)
Debug.Print AscW(Mid(Text2.Text, x, 1))
Next
it returns 27489 and -28722 (not 27489 and 36814)
edit:
on a side note, anyone know how to input unicode characters from a file into a textbox? ive tried but it seems the max char i can get is 255
Building Char Strings, Chars ASCII > 127 & Chinese Windows
An app (VB) that we have had running for a few years now has been working fine on American and European versions of Windows. Now someone has tried to run it on Chinese Windows, and it's not working. I have traced it down to one specific thing, as follows:
The code builds up Modbus communications messages one byte at a time using VB's Chr$() function, like this:
strMessage = Chr$(1) & Chr$(3) & Chr$(0) & Chr$(48) ... etc.
Now, as we all know an unsigned byte can be from 0 - 255. Also, in a single byte character system, ASCII characters also go from 0 to 255. Thus, it is quite natural to want to add such bytes beyond 127, which would be negative values _if_treated_as_signed_bytes_:
strMessage = strMessage & Chr$(245) & Chr$(136)
Now, on most systems this works just dandy. But I have discovered that whenever we try to add a byte (character) > 127 under Chinese Windows, it instead ends up with 0 there - it doesn't seem to get it right.
All suspicions point to MBCS (multi-byte character set) issues, but I was under the impression that VB handles this automatically.
Can anyone suggest how I might successfully add bytes > 127 to a VB string, using VB methods? When I get totally desperate I can call to a C++ DLL to do it, but there's a fair bit of work rewriting the VB code for that so it's a very last resort!

How To Convert Integer To Char?
I have a c++ function that convert an int type to char type, and I need to write a similar one in VB.
Can anyone please help me?
The c++ function is:
template <class T> void ConvertToChar(char* buff,T item)
{
int itemSize = sizeof(item);
for(int i=0;i<itemSize;i++)
{
buff[((itemSize-1) - i)] = char(item);// extract each byte, starting with hi byte
item >>= 8;
}
}
The call to the function is:
short mMsgLength;
char buff[2];
mMsgLength = fGetMsgLength(); // returns unsigned short
ConvertToChar(buff,mMsgLength);
Thanks,
Kruvi

Convert .wav To ASCII
Hi,
I would like to convert a file in wav format into txt format, so to obtain a vector of numbers to create a graphic, with a program, like excel, that is not Matlab.
Exactly I've an algorithm in Visual Basic that analyses a vector of points (graphic) and then gives me in output a series of parameters.
In matlab this is easy, because it recognizes wav files but if I would like to do the same thing in Ms Access, I've to convert before, the wav file in txt file so that my algorithm in Visual Basic can analyse it.
Anyone knows if there exist some algorithm or code that convert wav files in ASCII text files?
Thanks

Convert 5 Lines Of Hex To ASCII
OK, I have been reading up on ASCII but still can not get this right.
My app reads from a device on com port that sends 5 lines of ASCII code
Example
Quote:
49 02 01 00 00 00 31
49 02 02 47 36 4B 44
49 02 03 35 34 59 58

49 02 05 34 38 33 32

Which I need decoded to
Quote:
1g6kd54yx2u134832
The documentation I have found says this
Quote:
Returns 5 lines, A is line ordering flag, B-E ASCII coded VIN Digits
So I guess the 49 02 of each line is to be ignored?
and the rest needs to be converted?

Convert Characters To Ascii No.
i have an array called chars(). when my program runs, 1 character is stored in each variable of the array eg. chars (0) stores 1 character, chars(1) stores 1 character and so on. i heard that there are 256 ascii characters, is there a simple and fast way to convert each character into its ascii number, say chars(0) had the letter u stored in it and the number of u was 132 then chars(0) would be changed to 132
thanks

Convert Ascii String To Hex
Hi. I am having a problem finding the syntax to convert a 2 charactor String to a Hex value. The String will always be 2 charactors in length and will have ascii values from 00 to FF. Once in Hex, I will be using the value to set the .Height value of a Shape (Rectangle) which will represent the signal strength of a radio receiver. The receiver reports the signal level as a 2 charactor String, 00 to FF. I have tried a few different things and var types but keep getting a Type Mismatch.

Convert ASCII To Unicode And Back??
This may be much simpler than I think, but I haven't found an answer yet...
I need to convert ASCII characters to Unicode and back.
I'm looking to get the actual code that I can use, say in a web app. i.e. "u00e9" (I understand I'll have to add the 'u' myself...)
So, how can I input "A" and get the correct unicode equivalent?
Thanks.
