When I try to verify the signature in Acrobat I get the following error message "there are errors in the formatting of information contained in this signature (The signature byte range is invalid)".
Here's the link to the signed file if anybody wants to have a look: https://drive.google.com/file/d/1KTUfZwFeEjz5EKG61I7uuUzn6pyouEF7/view?usp=sharing.
Please help to verify the signature and share the same.
Your file contains two concatenated copies of the same PDF. If you split it in half (after 441805 bytes), you get a single copy of the actual PDF. If you validate the signature in it, you'll not get the error message "there are errors in the formatting of information contained in this signature (The signature byte range is invalid)" anymore.
Adobe Acrobat complains because the byte range covers only half the file of a seemingly single-revision PDF while it only accepts signatures covering the full revision (except the placeholder for the embedded signature container) signed by the signature.

I have a PDF file that I am trying to parse text out of. I opened the file using Microsoft Word, and text I need is in the header. On the first page, the header is justified left with a center tab that has the text (plain English name document title instead of the complicated reference name) that I am trying to grab. There is a right tab that has a page number control that I don't care about.
When I try to run the following:
Debug.Print ThisDocument.Sections(1).Headers(wdHeaderFooterPrimary).Exists
it gives me True, so I know the header exists. However, when I try to run
Debug.Print ThisDocument.Sections(1).Headers(wdHeaderFooterPrimary).Range.Text
it gives me nothing but an empty string, which I can further confirm by wrapping it in a Len(…) command which gives me 1. How can I get the text out of the header?
Of note, I tried using some Adobe SDK functions which would have been easier, but I do not have the professional Acrobat suite so I do not have access to those tools. Hence the MS Word workaround.
I've been trying to establish why a number of rtf files (opened and edited by multiple users from a network drive) have seen certain styles convert to Symbol or Wingdings fonts.
One lead I'm investigating is the file encoding (ActiveDocument.TextEncoding), which returns a result of -1 for all files. I couldn't find this on the MS list here. Can anyone tell me what the value of -1 means/translates to, please?
I am working on developing an expert system using CLIPS. For the case at hand I need to read data from a excel file. How do I do that? Or what solutions do you propose? Thank you in advance.
You can use the open command to open a file for reading in either text or binary mode. If you opened a xlsx file in binary mode, you could use the get-char function to retrieve individual characters from the file. There's no built-in functionality for parsing a xlsx file, so you'd have to add code to do the parsing and create appropriate CLIPS values from the data. If possible, it would be easier to save your excel file as tab-delimited text. If each cell is a valid CLIPS token, then you can use the read function to retrieve the cell values. If each cell is not a valid CLIPS token (for example, a cell representing a string that has spaces but lacks quotation marks at the beginning and end), then you need to use the readline function to grab an entire row of data and then use some of the string functions to locate the tabs and split the string into valid tokens.
I make program using vb.net where it connected to barcode scanner using rs232 connection. As generally, I use serialport communication (SerialPort1.ReadLine) to get data from barcode scanner. First I think it's work because the barcode value appears in the textbox until I get it can't show the data which has relation with barcode value.
The barcode value is same with data in database, but it can't show. So I try to copy the data from textbox then found that there are the undefined string in the last character of textbox. It's like space but not, when I copy that textbox value to the winword, the value enter automatically, so, i just want to know how my programs can read the barcode value without that undefined string.
Thank you,
When a bar code scanner is configured often the default is to add a termination string called a suffix or a postamble. The termination string is useful to tell the receiving program that all of the data has been sent.
It can be set to anything; a common configuration I’ve seen is the carriage return (vbCr) linefeed (vbLf) pair. You could also set it to not send anything additional which is also a common configuration.
You can build in a configuration option in your VB code to specify a termination string. Your program would look for this termination string as you are receiving the data from the serial port and then strip it out before sending it to the next part of your program. This allows you to easily handle various scanner brands and configurations by changing your configured string.
It is possible for serial data to be delayed and not receive everything at once. By checking for the termination string you can be sure you received it all before acting on it. If you have data but do not see your terminator save the received string and add the additional data as it arrives.
Bar code scanners also have a suffix or prefix that is prepended to the beginning of a scan. This can be used to identify the bar code symbology or other useful information. Usually the default I’ve seen is not to send anything.
I have another solution and I think it's better solution then using NewLine property.
Actually the character in the last string of barcode value is vbCr or vbLf, I don't know what that's mean, but I know it in the manual of barcode scanner. So to remove that character we can use mid function and replace that character with this string "".
I have a pdf file. Then i select and copy "K([2.2.2]crypt)]5[Co2Sn17".
But in clipboard there is "KACHTUNGTRENUNG([2.2.2]crypt)]5ACHTUNGTRENUNG[Co2Sn17".
Any ideas what is "ACHTUNGTRENUNG"? Is it a kind of protection?
There likely are a few extra (invisible) characters in the file. When you copy the text, the application you use to copy translates the characters in the PDF file into something that can be stored on the clipboard. Most likely that happens by translating every character into the unicode string stored in the PDF file for that character in the used font.
For most normal characters the Unicode string should be the same as the character you visually see; here you probably have invisible spaces in the PDF file that are called "achtungtrenung" in the font.
If you have the PDF file available somewhere, I'll be happy to take a look and verify this is indeed what is happening.
It's extra characters between lines.
You can try the PDF Copy Paste software, and see if your desired portion can be converted to text of your preferences.
