Closed Issue: Problem with Code128 barcode [8069]

DementedDevil — Thu, 16 May 2013 11:19:13 GMT

I'm trying to render the value "45870200000020000050009" using Code128, but the generated imaged can't be read by any reader. Any hints??

Closed Issue: Error in Code25 Interleaved ? [8820]

DementedDevil — Thu, 16 May 2013 11:19:13 GMT

Thank you for providing this tool. Comparing the output from this tool for "1234567895" gives a complete different result as listed on

http://en.wikipedia.org/wiki/Interleaved_2_of_5

Also trying "03239950" against the testpage

http://www.spatula.net/proc/barcode/i25.src

gives a complete different result. Am I totally wrong here?

Closed Issue: Error in code 128 [10019]

DementedDevil — Thu, 16 May 2013 11:19:12 GMT

When I try to get the Barcode in code 128 for strings like D1-21-1-210-10028436 there is a problem I `m getting non-printable characteres in the fifth position.
I think the problem is in Code128.cs

private string GetSetBlock(string text, out int set, out string subBlock)
{
// Needed to ensure glyphs allocated.
GetGlyphs();

BlockParserState state = BlockParserState.Free;
int index;
for (index = 0; index < text.Length; ++index)
{
// Check for Set C
// NOTE: This check eliminates two digits per iteration
if (char.IsDigit(text[index]) &&
index < (text.Length - 1) &&
char.IsDigit(text[index + 1]))
{
++index;
if (state == BlockParserState.Free)
{
state = BlockParserState.UseSetC;
continue;
}
else if (state == BlockParserState.UseSetC)
{
continue;
}

}

....

When you are already using another set you get directly to a break and you have already added 1 to de index.
So I think the solution is adding and else like this

private string GetSetBlock(string text, out int set, out string subBlock)
{
// Needed to ensure glyphs allocated.
GetGlyphs();

BlockParserState state = BlockParserState.Free;
int index;
for (index = 0; index < text.Length; ++index)
{
// Check for Set C
// NOTE: This check eliminates two digits per iteration
if (char.IsDigit(text[index]) &&
index < (text.Length - 1) &&
char.IsDigit(text[index + 1]))
{
++index;
if (state == BlockParserState.Free)
{
state = BlockParserState.UseSetC;
continue;
}
else if (state == BlockParserState.UseSetC)
{
continue;
}
//This is the else I m adding to substract in case there is another set selected
else
index--;
}

....

Closed Issue: Wrong BitEncoding at Code128.cs [10515]

DementedDevil — Thu, 16 May 2013 11:19:12 GMT

The correct bit encoding for 'C' (char 35) is 10001000110 (0x446). This is causing the creation of unreadable Code 128 barcodes. I will continue to use the framework in production, so I will correct and report any other problem found.

DementedDevil — Thu, 16 May 2013 11:19:12 GMT

Good morning,

While testing, I discovered that the bar codes beginning with 47 with the code 128 symbology give false results and not read. If I find more mistakes, I will inform.

Here I leave some examples:

47008
47162
47100
47162

Thank you very much for this framework

Open this page in browser and print it. I have 5 different types of scanners like Symbol and Cipher and no one of them can not read this printed barcode.
I generated this barcode by DevExpress which this scanners read OK. It's easy to see a little difference in these barcodes.
You can find these test barcodes as PNG here http://cid-e9a4711d718d8369.office.live.com/browse.aspx/Bugs/Barcode%20render

Closed Issue: Code128 barcodes missing characters when scanned. [14801]

DementedDevil — Thu, 16 May 2013 11:19:11 GMT

I support a custom C# WinForms application that uses Zen.Barcode.Core to generate barcode images in Code128. When the application was first created it only needed to create barcodes of serial numbers in the following formats: 99999999-9 and 99-99999XX-999. In these formats I do not believe any issues were encountered. Requirements changed and the data formats became 99999999-99 and X99-99999XX-999. Now the barcodes for both of these data formats are not generated correctly. If I have a serial number of 01234567-89 the barcode when scanned will return the text 01234567-8, and a serial number of A01-23456BC-789 when scanned will return the text A0-23456BC-789. I have used the included BarcodeRender WinForms application to confirm it is an issue with the Barcode Rendering Framework. The custom application I support uses version 2.0.3.0 of the framework and separately I have confirmed that these issues still exist in version 2.1.0.0 of the framework. Please see attached jpg image.

Closed Issue: SSRS Control not usable on Footers and Headers [15346]

DementedDevil — Thu, 16 May 2013 11:19:11 GMT

Hi,

I'm getting an error when attempting to use the Barcode Item in the header or footer of an SSRS report. We want to use it for forms and documents like Invoices, Purchase Orders, etc. where we would print barcodes but want them to appear on every page. Is there any way to circumvent this?

Thanks

Is there anyway I can guarantee that a Code 128 barcode is generated using type "A", with the SSRS component?

New Post: Barcodes appear in preview of BIDS, but not when deployed..

jonfehringer — Wed, 27 Feb 2013 17:27:21 GMT

Within SSRS 2008r2, I have reporting services installed to a second instance of SQL on a secondary HD. I am developing the report on the server within BIDS and the barcodes generate perfectly within preview. When the report is deployed, however, the barcodes are missing. I have copied the Zen.Barcode.Core.dll and Zen.Barcode.SSRS.dll into the ReportServer/Bin folder of the second instance without luck. Any help would be greatly appreciated. Thanks, - Jon
