ASCII table

[shirishdawane]

Hello All,

I need to display all the characters for ASCII values 0 to 255.

If its possible to display those characters in listbox then that will be more helpful.

Actually it should happen that w.r.t to ASCII code it should display respactive character into listbox.

eg. 
ASCII Value     Char. to be display
65                  A
146                Æ
05                  ♣

Note: Please see below attachment of ASCII table.

Just use the chr function and Print the values out to a file or load in a listbox or listview control.

Afaik you can see those characters by using Terminal font:

List1.Clear
    List1.Font.Name = "Terminal"
    For lngA = 1 To 255
        List1.AddItem ChrW$(lngA)
    Next lngA

Afaik you can see those characters by using Terminal font:

List1.Clear
    List1.Font.Name = "Terminal"
    For lngA = 1 To 255
        List1.AddItem ChrW$(lngA)
    Next lngA

Thanx both of you for such a quick & informative reply..........

please see attached exe of ASCII table but after comparing it with attached image so many characters its misprinting.I guess its because of font....
I have used same font as mentioned by Merri

List1.Font.Name = "Terminal"

can you resolve this problem.............Thanx in advance....................

[Merri]

Do you know which character set that is? Knowing it is ASCII is not enough, because ASCII can be so many different things. What you see in the listbox with Terminal font is the OEM character set (I guess that means it is the same as the most common DOS character set).

[shirishdawane]

So how shall I solve my problem.............

[Merri]

Humm, so, what is the actual problem? Do you need to show the specific characters from that table? What will be the use?

[shirishdawane]

Actually I have to implement this functionality in my official project that is why I am trying to do it for testing purpose.

Customer send me standard ASCII characters image (attached image) for reference & they want in same format as mentioned in image.

I hope now you can understand my problem............

[Al42]

What font are you using? If you set the textbox font to Terminal, it'll show them the way you want. About the only character you can't produce is 9, HTab.

So how shall I solve my problem.............

Use Terminal Font and CHR$ not CHRW$

[shirishdawane]

Use Terminal Font and CHR$ not CHRW$

Yes I have done changes as per told by you but no use because from 1 to 127 its printing correct then from 128 to 255 its misprinting characters as shown in attached jpg image.....

I have attached code of my project...........please have a look on that tell me what changes are nned to be done now...............

[Sawdust]

Looked at your attached code from post #11 and it showed a bunch of question marks (?) for some of the characters. When I changed "chrw$" to "chr$" (as suggested by post #10), then all of the characters appeared properly.

[Merri]

I tried to find what is the actual character set but I just can't find that one. Until we really know what it is, there is no way we can get the correct characters.

Terminal supports and shows up as OEM/DOS character set, which is not that character set we can see in the image you have provided.

You can have fun yourself looking through all the nice pictures Google provides

I found it! It is multilingual codepage PC-850 aka CP-850: http://www.nefec.org/UPM/spc850.htm

I now know how to get the correct Unicode character codes (UTF-16) for the characters, but I don't (yet) know of any font that could be used to display the results correctly.


Edit!
Here you can find a Terminal font. Just install the font from New850.zip and then Terminal supports CP-850: http://www.uwe-sieber.de/dosfon_e.html

I don't know how exactly the change triggered, though. Also some special letters appear to be missing, I'm not sure why. Probably the font doesn't support them.

[Al42]

It looks as if the original table, as shown in post 1, was generated using a character generator IC (2513?) I don't think that can be duplicated by any Windows font. close, yes, but not exactly - unless by making a character generator chip available to the software (which would require a plug-in board or USB device of some sort).

Or maybe I'm wrong and MS has exactly duplicated the old chip in some code page.

[Merri]

The problem is that there is no font to display all the characters. I can use MultiByteToWideChar to convert from codepage 850 to Unicode and each character gets unique Unicode code and I'm pretty sure they're "correct", but none of the fonts is able to display the exact wanted result for the special characters (ones that are used for style/design and not for information).

In the other hand the font I found is able to show most of the characters pretty close to the wanted end result (and there is no need for character set conversion, just give 0-255), but seems to lack some of the special alphabets; not all of them, but still all too many.


So it is kind of a dead end here: either use the additional font and install it with the installation of the program or then be happy with Windows' ability to convert the character set from codepage 850 to Unicode.

Cheersssssssssssss......................

I have downloaded & installed CP-850 font on my machine & now its working fine as I wanted.........

Guys, thanx a lot for ur valuable informations............

Hi All,


We are facing following problems with MS Sans Serif Font:

For a notepad if we set the font to MS Sans Serif,Bold,8 points and paste some ASCII characters such as ¹³²~ repeatedly some extra empty spaces are added with every paste.

Same case is happening with textbox having Ms Sans Serif,Bold, 8 points font set.

Why is it so?

STEPS
1. OPEN NOTEPAD
2. SET FONT TO MS SANS SERIF,BOLD,8 POINTS.
3. PASTE THE CHARACTER ¹³²~ REPEATEDLY.
4. U WILL SEE BLANK SPACES ADDED AT THE END OF STRING.

Sorry, I couldn't replicate this problem. I tried both Alt + 132 character (ä) and Alt + 0132 („).

This problem might be specific to the locale and country version of Windows you are using.
