i am able extract TEXT from rtf file, but i am unable to extract and convert to images as bmp or jpeg or gif and save them to harddisk.is there any options for converting hex/binary to image?i tried to hex to base64, still it no-use
View 1 RepliesWhat I'm wanting to do is add something to my software that sort of acts in place of an archive by saving pictures an audio clips as string.
I want to be able to save an image/audio clip to a string, and then pull that data from the string again and convert it back to an image/audio file. The purpose of this is so that I can save multiple images and audio clips all within one string, using datasplits to later separate them again.
Basically, what I had in mind was saving an picture/audio file to a string setting (let's call it my.settings.audiofile), and then pulling that string setting and writing it to an jpg/mp3 file using my SaveFileDialog.
So, how would I write raw audio/picture data to a string?
I am trying to write some code to my program that will allow the user to rename and save a pciture they have selected, here is what i have so far.it saves the picture but not in a jpg file type, the file type is "file"

I don't know how to add an savefiledialog to a picture viewer that you can build like in the first Microsoft tutorial.

I have a situation where certain information from PDF documents is entered into a Data Base. I need an easy way for a user to do this. So given a situation where a data entry program is running, then certain data is taken off a PDF document, then entered on to a data entry form etc. So it would be nice to say, have a user click on certain entries on the PDF document, or the document itself and then have the required data load on the data entry form automatically, with using cut and paste on each entry. Note the required data from the PDF document is in same each time, just different values.

I have a insanely large file that has a lot of customer data in XML format. The start of a customer and end are how I'll determine the starting and ending points of the customer data I need to extract. The is the number I'll be searching for. I'll input a regular text file with 12-byte document numbers into the file (Doc Number List.txt), search the massive XML file (example.xml) for those document numbers, find the data before and after the DOC_NUM tags, but within the CUSTOMER tags and extract it to a formated file. The formated file needs to have these tags, <?xml version="1.0" encoding="ISO-8859-1"?>
View 1 RepliesTo simplify what I am trying to do, let's say I have a text file with only one line of data.
The data in this case is color info for one pixel:
Color [A=255, R=255, G=200, B=128]
What I am trying to do is read the text file and extract the hex color info and save them to their own variable.
So once the code has run, these should be the contents of the three variables.
RedData = 255
GreenData = 200
BlueData = 128
I have managed to get something to work but I know the code is terrible and is incredibly slow when I try to run through hundreds of lines in a text file.

View 1 RepliesI've used Python on and off for the last decade in a very limited capacity (mostly to do my math homework), but this project I'm working on now is almost overwhelmingly complex and difficult to me. Mostly due to my lack of immersion in programming as a whole.
Anyhoot: here is what I'm trying to accomplish: part of our new VoIP system is an enterprise messaging component that will take a voicemail, embed it into an email (as a WAV stream), and then drop it into the email address associated with that extension. However, if that user is not configured to use enterprise messaging or if they've not opened their email client in awhile, the voicemail+email object just hangs out in a folder on the enterprise messaging server. When an employee is terminated, the EM server continues to take VMs and store them in this folder.
As a part of the directive from management, we've been instructed to deliver these voicemails to the employee's manager for review before we pass the extension and mailbox onto someone else. What we've been doing up until this point is opening the VM+Email objects in Notepad++ one at a time, removing the email data from around the WAV file, resaving it with a *.wav extension, and them attaching them before sending them along.
Suffice to say, this process becomes very tedious and error prone when you have a TON of these to work with. I thought that I could use VB2008 to automate it.
The code I wrote grabs the VM+Email object as a text stream, uses an InStr() and InStrRev() function to identify the beginning and ending points of the WAV stream, and then uses a Mid() function to extract it before resaving it as a WAV file. This works, but the problem is that the WAV file it saves is barely audible and it sounds awful.[code]...

I have found the above code from the net and it works fine as I would expect. I know this because I have added a put the String StoreFile into a text box and it worked. From what I understand about the code above is that we are reading the file test.txt until we reach the end of the file and we are storing it into a string.
What I would like to do is either:
1. Search the String StoreFile until I find the text of my choice, and then extract the characters around it. See attached txt file.
For example, if I wanted to search for MNAUSD in the attached txt file, I want to grab the values on the line (highlighted in blue) and make them available to my program and ignore everything else.
"MNAUSD",UNITED STATES,US $,M,1.558850,1,1.369850,1.113500,L
I know these files are comma delimited, but I would rather use a regular expressions if possible as I have other files that are not comma delimited, so it would be ideal if I have a regular expressions to handle the search and extract
OR
2. Search the File test.txt LINE BY LINE, until I reach my search text MNAUSD and then extract the same values as above.
I have a file that contain data structure as below:
L,13206,11,02,06,000,3981.100

so how can i extract 1 and -18970.811,53728.643 and export it into a new output file with new structured as below: C 1 -18970.811 53728.643 For your information, the value for -18970.811,53728.643 will be placed after string K,1,P or K,2,P or any number between K and P...
One more thing is i want to append that new formatted data into old ready file that already contain old data... new formatted data will be append to the top of the old file..
I am desperate in solving the following puzzle: I use a thermal camera (a camera that captures thermal images by working in the infrared spectrum).The camera produces thermal jpeg files that includes visual (the picture one can see) together with the thermal data (thermal energy levels) in one jpeg fully radiometric(=file that holds energy data) file.
What I want to do is to try to extract the energy level data for each and every pixel of the image (usually 320X240) and store it in a table, using my old favorite vb.net if possible.
Now i have a webbrowser that opens a site i want to extract the pictures from the opened site into the pictureboxes but i don't want to load these pictures again from the net?
View 1 RepliesI am using Streamreader to read a text file containing data such as the following:
IN;SC;PU;PU;SP1;LT;VS10
IN;SC;PU;PU;SP1;LT;VS10
PW5;PU4179,27448;PD4179,29951;PD3244,29951;PD3244,30286;PD5494,30286;PD5494,29951;PD4555,29951;PD4555,27448;PD4179,27448;
The final goal is to use the numbers next to the PU and PD characters to perform specific calculations.
Essentially, I think the code needs to do the following:
1. Read each block of characters ending in a ";"
2. If the block commences with anything other than PU or PD, discard it
3. Extract the numbers in such a way that calculations can be performed. The following is an example:
x y
PU4179,27448;
PD4179,29951;
[Code]....
Essentially, there will be hundreds of these rows and I will need to sum up the deltas so that a specific formula can be applied.
I have tried doing this a number of ways but each seem very inefficient (using text boxes to store/swap data and creating additinal text files are 2 methods I have tried) and so I'm looking for some direction.
I need to load and parse a text file and extract data between points on any given line. I can load the file, but it's the parsing that's giving me headaches. e.g. "Phoned Jim and arranged for John to attend site" First I need to search for "Phoned" because the line always starts with that, and then I need to extract "Jim and arranged for John"

I have a form with a listbox that when the form is opened I need it to display info from a file. I don't know what would be easier to work with Excel or a txt file, but it is in this format:

999-555-8618[code].......
I would like it to populate the list box when the form is loaded, but if I have to use a button to tell it to load that is fine also.On the same form I have 4 textboxes that ask for each of the above items (name, DOB, Level, PH#) and a button that when pushed I want it to save it to the same file where the above info was pulled from in the same format.The Show Contacts button doesn't have to be used if it is not needed.
