At least you should have searched in CP, I found this

C# Barcode Generator WebService[^](Create a code39 barcode using a webservice in C#)

Also you can find more in Google.

The solution is easy; you study the information in Wikipedia then use that knowledge to design and write your program.

It's a shame I cannot vote this. My virtual 5.

My virtual 5 back to you, now we have both virtually advanced. :))

CPallini 9-Jul-11 8:04am

You know, we two, being native, are already far advanced with respect all those 'managed' folks. :-D

It's pretty funny, but hardly offensive, you should try a better translator! :-D

Member 7925220 11-Jul-11 8:08am

in future i think u see some more folks are advance then u so don't try to underestimate others

CPallini 11-Jul-11 8:13am

Do you understand irony?

CPallini
i know its same bt Iam just a student not professional like so if i doest know any thing i just try to learn that. So please help me

CPallini 9-Jul-11 8:02am

You are actually a lucky student, because the Code 39 looks very simple and you probably have just to find the appropriate font to easily rendering them.
If you cannot find the right font then you may try to implement the rendering algo yourself (maybe using the Windows graphic primitives): just try, we'll be happy to help you then.

Member 7925220 9-Jul-11 8:28am

i am very thank full for your reply I just not able to find appropriate font so please help me sir i am thankful to you

Member 7925220 11-Jul-11 8:05am

now em made my barcode 39 generator thanks Cpallini but it not save

CPallini 11-Jul-11 8:15am

How do you made it (i.e. it is an image?)? Do you need to export it as a bitmap or you need a printout?

Member 7925220 11-Jul-11 20:53pm

Oh u take wrong way thats not insult its means u r typical who simply not help others and thats thing really help me if u simple tell the solution then em not able to know that much about barcode so thanks.

OK, let's see how to approach the problem.
1. You know the Code39 rules from the link provided by Sr Pallini
1.1 Each character is represented by a series of black or white bars.
1.1.1 Set the narrow bar width equal to the minimum width required (1 pixel?)
1.1.2 Set the wide bar width to twice (or three times) the narrow width
1.2 For each bar in the character's pattern:
1.2.1 If bar is white move the origin right by the width of the bar
1.2.2 If bar is black then draw a black rectangle 3 or 4 characters in height and the width required.
1.2.3 Calculate the total width of this barcode set
1.2.4 Print the actual character below the barcode centred in the width
1.2.5 Repeat for each character

Give some thought to the variables you need to create and the steps you need to take to solve this problem. Once you have your solution written down it should be a fairly simple matter to write the actual code required.
