Nov 17, 2009I want to read a PDF file having lots of text, images, tables in it. I want to read the entire file content by content page by page, from top to bottom.
For example:
The top of the page contains the Heading
Then on left hand side the contents and on the right hand side images
So I first want to get the heading then the contents then the images. Is there any Open Source for reading the PDF or any coding reference for .net 2.0 or greater version.
Cannot Read Contents Of Text File On Website
Jul 18, 2010I'm trying to read the contents of a text file. Everyone says it's a piece of cake, but I still get error "404 Not Found" even though the site exists.
I'm using the following:
Dim myRequest As HttpWebRequest
Dim myResponse As HttpWebResponse
myRequest = HttpWebRequest.Create("[URL]") 'This does work
myRequest = HttpWebRequest.Create("[URL]") 'This does not
myRequest.Proxy = New WebProxy("http://proxy address", True)
myRequest.Method = "GET"
myResponse = DirectCast(myRequest.GetResponse(), HttpWebResponse)
When I hit the [URL] the myRequest.GetResponse command passes the contents of the site into myResponse. However, hitting the [URL] always returns 404 even though it exists.
Read CSV File And Store Contents In Array
May 25, 2010I have developed a vb.net dll (.net 3.5) which does the following :
- I have data of several stock market companies.
- They are stored in several folders under a main folder.
- These files are random access files.
- There can be around 4000 files in total for example.
I wrote a program which reads a current csv file and stores contents in array. Then I store name and path of companies in folders (which I was talking about). Then I match one company from csv (stored in array) to companies in user's folder (again reading from array). If found I insert data in the file (random access file). This whole process takes for eg. 2 min my system. A similar program was written years ago by someone in powerbasic which takes slight less time if run one but if run for multiple csv files it takes only a few seconds doing the same thing for other files. When I do the same thing (by writing code to .net dll) and making a dummy app to run it, no matter how many times I run it takes same time. And is way slower than the earlier one (PB) one I was talking about. But if I paste the same code in my win (.net) app and not use .net dll then it runs a bit faster.
I need to show status so if I pass my form's label reference to .net dll and it updates it does that slow down process a lot. As I mentioned I am trying to process the files and it takes longer in .net. What should I do to get best performance? Unfortunately due to unexplainable reasons I cannot change the format or use a db. The files which I am reading/writing (random access files) are use by other products so I have to stick to that format. What I am doing is storing the location of those files in array so that I don't have to search folder again. that is not taking time. But opening reading and writing files is time consuming if I am doing it for few thousand of them. A similar program in powerbasic (developed years ago) runs fast. Running code thru .net dll is slower than running it thru program. Why?
Read Text Contents Of Smart PDF File?
May 21, 2009I'm wondering whether anyone else has had to do this. I've looked in to some third party solutions.
The two I've used with the most success are: 1. xPDF. This includes an executable, PDF2TEXT.exe, which takes an argument that is the path to the PDF file to "read" and a second argument which is the name of the text file where it will write the output. This works well and fairly quickly, but it's external to my application and calling it via a Process.Start() command raises security considerations and requires to user to allow the external executable to run. They must allow this to happen AT LEAST every time they run the import application (IF they will check the "Don't keep bothering me about this" box).
2. A solution from Foxit, which is GREAT, but costs a good bit of money to use. Does anyone have a solution that I can implement IN MY CODE (like #2) but that's free (like #1)?

[2008] Read Contents Of ZIP File (without Unzipping Preferably)?
Mar 5, 2009I need my program to 'take a peek' into a ZIP file and see if it contains a certain file. I need it to do this many times for a large number of files, so I would prefer it without having to unzip the entire zip-file each time, as that would take far too much time (it's a fairly large zip-file of about 250 MB).Also, I don't need the actual file at all. All I need to know is if it exists inside the zip file.
vb.net
If IO.File.Exists("C:FolderIPFile.zipfolder_in_zipfile.jpg") Then
' "file.jpg" exists inside zip-file!

Read Contents Of Textfile Into Listbox?
May 15, 2009I'm trying to place the contents of a text file (just a list of names) into a list box when the form loads.
My code currently looks like this:

View 2 RepliesDeviceIOControl Function - Read The Table Of Contents From A CD
Aug 25, 2011I'm trying to read the table of contents from a CD and am having problems with the DeviceIOControl function. When I call it with a control code of IOCTL_CDROM_EJECT_MEDIA or IOCTL_CDROM_LOAD_MEDIA it works fine, and opens or closes the CD drawer. But when I call it with a code of IOCTL_CDROM_READ_TOC_EX it gives an error code of 6 (ERROR_INVALID_HANDLE). I'm using the same handle, so I can't see why it's complaining. It's possible that the input data that I'm giving it is wrong, but I don't think that it should give this particular error in that case.

C# - Open A Read Only File As Non Read Only And Save/overwrite?

Is there any way to open the file in read/write format? I should have admin privileges so access isn't an issue.
I'm using VB.net to open the files. More specifically
doc = word.Documents.Open(path, Type.Missing, False, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing)
