This a Barcode generator with bar39 and bar128.
THIS BARCODE GENERATOR IS SIMILAR TO INDUSTRY RENOWN PRODUCT 'ACTIVEBARCODE' IN FUNCTIONALITY. I've put detail description of how these codes are generated. If you are a beginner or a novice to Barcode, it helps you to understand the Barcode algorithms I've used.
I've developed it from scratch.
Now with these algorithms, you can create your own barcode and use it in diffrent purposes.
What is barcode ? A barcode is a machine-readable symbol used to encode information in order to automate a business process. Examples of business processes are retail sales, shipping and tracking, inventory management, warehouse management, asset tracking, and automated data entry.
CHECK THE Readme.htm FOR THE DETAIL DESCRIPTION.
_____________________________________________________
Update on 12th Dec 2002-> A bug on printing Char '*' on Bar39 is fixed.
_____________________________________________________
Update on 11th Oct 2002 -> Export the Barcode to Gif and transperent Gif with completely independent Export Class.

Very good code and good implementation Can this be extended to other formats such as code 3 of 8 etc (If this comment was disrespectful, please report it.)
Nice work. While I do not want to advertise something I made here, if you are interested in somebody elses approach, I will be happy to show you the technique I used to do the same thing. The code is far an actual active x control instead. If interested, you can just email me back. If you want to see at lease the control now, you can look up my bio to get my web address...dont want to type it here to have people thinking I am just advertising. Good job though. I just want to share if you are interested in seeing other methods (actually a little less complex). (If this comment was disrespectful, please report it.)
Man, sorry for all the typos...I got inturrupted while typing twice. far should say FOR and lease should say least. Anyhow...I am sure you understand what I was trying to say. (If this comment was disrespectful, please report it.)
Another thing if you are interested is to visit http://68.70.175.54:123/scratchpad/index.asp to see how a web page can generate the bar code as well. (If this comment was disrespectful, please report it.)
Its really great code!!. I found It as most fastest way of printing the barCode. It also has nice way of presentation especially the readme.htm. Thanks

Hey Guys, All of you have visited 1239 TIMES , and only 14 Votes and 10 Comments!!!! What restrains you from giving vote and Comment to THIS GUY. He had really done a excellent job. Till Now ,in PSC, nobody had submit a BARCODE generator like this. COME ON GUYS !!!! (If this comment was disrespectful, please report it.)
Thanks you, I tried to make the concept of barcode more clear through the HTML help, I really need some feedbacks from you. regards -Author (If this comment was disrespectful, please report it.)
Nice work! Very well explained and simple to understand, even for a me who is *new* to barcodes...5 from me (If this comment was disrespectful, please report it.)
Nice Example Of Barcode Generation 5* Keep It Up. (If this comment was disrespectful, please report it.)

Nice work! Works well with my commercial barcode scanner as well as with the Radio Shack one. Thanks. I was looking for something like this, so I can full around with my scanner. I give it a 10 out of 10. (If this comment was disrespectful, please report it.)
Hi Opal, It is Same. If you want to verify the String 'DATA' on Code39, then Type 'DATA' on the TextBox and, right Click on Code39 PictureBox and Choose 'Save as ' GIF format . Then It will be displayed on IE or your GIF editor.Now Take Print out on A printer, Scan with Bar 39 Scanner, you will find that the Scanner will return 'DATA'. Check it out (If this comment was disrespectful, please report it.)
Ok theirs one indication that their possibly could be a problem with this program. This is because if you look at a real barcode their are at each side 2/3 lines indicating which way the barcode can be read from plus the same indication in the middle of the barcode. If you put these codes throught the optical reader they may not be picked up because their is no indication which way they are meant to be. Although Ive spotted this im going to give it a relitivley good vote neways I just thought Id let you know. (If this comment was disrespectful, please report it.)
Plus I forgot to mention these 'which way' indication lines are some what larger in length. These can be represented as normal unicoded numbers/letters but just thought I'd add it. (If this comment was disrespectful, please report it.)
hi Mark (WinCrypt), Please read one Comment on 10/15/2002 11:42:01 PM by one user. It was part of an already Implemented Project and I've checked both the Bars i.e., 39 and 128 on Optical Scanners. They Worked perfectly. If you check the BarCode Generator throughly, you'll find that the length, height, width and size are customizable on each Bar of this Program , subjected to Specific Hardware configuration. (If this comment was disrespectful, please report it.)
Hi Mark, Thank you For the Suggestion as a unicode representation.

I am new to this Barcode programming. Thanks to you, now that I can learn to code. Nice work. Thanks again. (If this comment was disrespectful, please report it.)
great code! One question though: are you limited on how long the barcode can be? (ie could I encode a 38-character guid?) (If this comment was disrespectful, please report it.)
gr8 job thanks is there any royalty for using the code? (If this comment was disrespectful, please report it.)
11/22/2002 5:26:08 PM:
Great code. Having converted it to print directly to the printer it worked great with my scanteam 2380 scanner. But there is a small bug you define the bc(65) twice as both the letter A and *. Thus it is impossible to create an A! Thanks Steve (If this comment was disrespectful, please report it.)
ANDEWM: The Barcode Generator doesn't have limitation upto length of bar, I've set the length of textbox named 'Text1' to 21 Character only for illustration purpose. So , you can set the 'MaxLength' of 'Text1' to 38 for your requirement. -Cheers Author (If this comment was disrespectful, please report it.)
Hi anonymous, Thank u for the bug reporting. This bug is valid for code 39 only and I've fixed and uploaded it. (If this comment was disrespectful, please report it.)
Great Work .. !!! (If this comment was disrespectful, please report it.)

I didn't check your code. Just now i have downloaded your code. Thanks for you, because u have metioned as this will help to know about barcode generation methods which i would like to know. I am giving you 5* because of the way which u have presented over here. (If this comment was disrespectful, please report it.)

Hey guy thanks very much. Great work.
One question : I haven't spent too much time on this yet but when I change the lRotation parameter on a Code 128 barcode, it fails to draw on the device Picture1 at all ? Any help there ?
Again, great work dude. Thanks (If this comment was disrespectful, please report it.)
2/10/2003 2:58:24 PM:
Also, how can I print the barcode to a printer ? If I change the device context to the printer's hDc, I just get a blank page. Any help there ? (If this comment was disrespectful, please report it.)
2/13/2003 12:15:56 AM:
Nice work! Ill give you 5* for this code. Could this be possible to print the barcode in a dot-matrix printer?
(If this comment was disrespectful, please report it.)
nice try! may i suggest using a vector based image file format. producing a wmf will have certain advantages over a bitmap in a gif -- it can scale painlessly and very precisely.
the most popular codes are the 'commercial' ones - UPC-A/UPC-E and EAN-8/EAN-13. you've implemented 'industrial' codes which are good for feights and partno's etc but are not good for products in a shop.
the commercial codes are the ones with 'indication lines' (as commented earlier) but almost every type of barcode is readable in BOTH directions -- so ignore the previous warning comments.
also note that commercial codes are somewhat more complicated to implement -- hope you update this code with UPC/EAN codes some time.

Great code. Really nice. A few people made comments about printing it, what is the best way to go about printing the label or better yet a sheet of labels?
(If this comment was disrespectful, please report it.)
Excellent program! Upon analysing the Bar/Space sequences I noticed the startcharacter is 131131. This doesn't match any B/S sequence of the 128 barcode specification. The Data sequence is correct. My reference for the Spec. is http://www.barcodemill.com/ Thank you, Dan (If this comment was disrespectful, please report it.)
4/3/2003 6:18:46 AM:
This code seems brilliant but I can't seem to get this code to work. I tried 'DATA' and it prints out a different barcode to the one shown in your help file and my scanner will not read it. The lines seem to be to thick. Am I doing something wrong (I must be as everyone else seems to get it working OK!), I am using WinXP and VB 6 (If this comment was disrespectful, please report it.)
4/3/2003 7:32:28 AM:
its me again, it seems the code39 is working fine but the code128 is wsomehow wrong. I put DATA into www.barcodemill.com to get correct code and yours is different - it is the start block that seems different - has the format changed or something?? (If this comment was disrespectful, please report it.)
Hi Dan Dierikx, Thanx for your verification. I've visited http://www.barcodemill.com/ to reproduce the difference between my Code and their Code based on your info. The basic difference between the codes is 1) My code generates CODE128B and barcodemill generates CODE128. 2) Code 128 and code 128B has little differences between them . So the outputs were little different - Author (If this comment was disrespectful, please report it.)

Dear Joy
Your code generates super barcodes to the screen. How can I print them to a label?
I tried a sample of something from messages above and it gave me an error code.
Thanks for your time

I did print the barcode out and test it with the barcode scanner. I print it using the bubble jet printer. However, i found out the Code 39 can be scan by the barcode scanner but the code 128 cannot be scanned. Maybe need to use other kind of printer such as laser printer to print the code out, just then, the code 128 can be detected by the barcode scanner. (If this comment was disrespectful, please report it.)
5/8/2003 1:47:49 AM:
a beautiful piece of code- thanks a lot for the same: am new to vb therefore have a query- can't v send the barcode thus displayed directly to the printer from inside the code itself (If this comment was disrespectful, please report it.)
Is their any VB.NET Version of this Barcode. Please Reply me at sawan@sawansoft.cjb.net (If this comment was disrespectful, please report it.)

Wow! - I've been waiting years for this application. Well done! I can print the missing barcodes from the early videos entered as made up names in my Media Library application [ http://www.planet-source-code.com/vb/scripts/ShowCode.asp?lngWId=1&txtCodeId=60524 ]. It didn't make sense to spend over $100 just for that one thing - so well done once again and keep up the good work. (If this comment was disrespectful, please report it.)
5/25/2005 7:47:31 AM:
Very nice code and very helpful. I'll try to add some printing functions. But everyone must Known that
(If this comment was disrespectful, please report it.)
How can I display my alphanumeric convertion of the barcode.How can I receive the barcode using my barcodereader, then convert it and display it alphanumeric? The reader makes an bip when I run it over the barcode, so I guess it manage to read the code. As for now, I would like it to write it into an label on the form.
By the way, great code! (If this comment was disrespectful, please report it.)
This is a very nice code, excellent for learning purposes. The only thing I would change is the option to save. Saving to the clipboard is fine, but additionally you could add an option that would populate a given form, document or spreadsheet with one or more barcodes by giving an alignment option. Printing the newly created document at the end would top this. Great Job. (If this comment was disrespectful, please report it.)
I'm at a total loss as to why people are commenting on "good code". This must be the worst piece of code I have ever seen in VB. It is badly structured, has an enormous non-modular prodedure, is badly formatted, has no "option explicit" which would show up some of the errors. Defines, initialises and tests for variables it never changes. I could go on, suffice to say the code is shockingly bad. The functinality, however is excellent, and if you close your eyes and choose to use the code without looking at it, then you'll probably be ok, I just hope no-one needs any modification of the code.
Sources for the display of barcodes are few and far between and I congratulate the author for sharing.
In conclusion, the program does what it says on the box, just don't be brave and look inside the box. I give it 3 globes, it would have been 1 globe for the code, but I'll give it more for the functionality. (If this comment was disrespectful, please report it.)
The 128 barcode generated is a perfectly valid 128 code. Code 128 uses 3 different character sets, so the same barcode symbols can generate numerous different images. For example, if the barcode just contains digits it can be encoded using A B or C, or even switch between character sets mid code. Don't assume that because the code you generate does not exactly match another code generated somewhere else that this code is not valid. (If this comment was disrespectful, please report it.)
Very Nice work,Appriciated. Hai dear how can i take the print out through the barcode printer ?can you mail to me bijojoseph@napcogroup.com please... Thanks (If this comment was disrespectful, please report it.)
nice work ,but how can i print direct ? cn y fix it .(i want to print without saving),please help me. my mail id fkmadhavan@yahoo.com (If this comment was disrespectful, please report it.)
Truly wonderful code. I have used in my own projects. In commercial projects, I use Morovia barcode ActiveX. (If this comment was disrespectful, please report it.)
Extremely useful. I've got it printing the barcode to a printer, but if I set the rotation to anything but 0, nothing is printed. Any ideas? (If this comment was disrespectful, please report it.)
I've tested your code, so I've : 1. scanned a barcode to textbox (using a CCD barcode scanner) 2. copied (copy and paste) all siz codes: both 128 and 39 on their three formats (Small, Medium and Large) to a Word document. 3. printed document into a laser printer (monochrome) 4. finally, verify each barcode using the same barcode scanner to check if correct. RESULT: Only the 128-medium format barcode is recognized. the other five formats are not recognized.
Your idea is good, but the result is not. (If this comment was disrespectful, please report it.)
it's very good and useful application. after draw barcode if you facilitated with some printing option like print many stored barcode in single page (If this comment was disrespectful, please report it.)
