View 2 RepliesA VS 2008 desktop .NET program needs to open a PDF file and read its contents as data. That is, the program must scan through the PDF file searching for certain text. The program will not merely open the PDF file and display the contents using a control such as an ADOBE Reader control. It has to actually read the individual data within the PDF.
How can a .NET program read data within a PDF file?

What my program does is load a file (password list), then progressively reads each line of text in the file whilst writing each line to a new file. After X amount of lines have been written, it should start writing the lines of text to a new document until the initial password list has been split into X amount of password lists. The problem I have is that after hours of tweaking, all I can get it to do is write either blank ocuments, or write all of the lines to only one file. I really need it to be able to split into multiple files, preferably at runtime rather than loading a whole text document into the program in a textbox or array then writing it to new files.Below is the source:
Imports System
Imports System.Windows.Forms
Imports System.IO

2 - Saves the server XML file it into a folder separate from the root folder of the application.3 - Deletes the local XML file in the root folder of the application.4 - Copies the server XML file to the local folder of the application.5 - Opens the application.6 - Closes the updater.Now when the application opens, it reads this XML file in the local folder. When I run it stand alone, it works fine and can find this XML file. However, my problem is when the application is opened by the updater, it can't read the XML file in the local folder. I check for this file doing File.Exists(XMLfilename) and it returns false but like I said, if I close the application and reopen it it works fine.
I'm thinking that for some reason the updater is "locking" this file so my other process can't read it? I can't close the process before I open the original application so I'm not sure what's happening here. My Update Folder is the users ApplicationData folder and the root directory of the application is in the Program Files folder.
This is my code in the updater:
Dim ImageDir As DirectoryInfo
Dim fi As FileInfo

1) I have a chat Program.
2) To access the Chat Program one has to put in ones Username and password in a Login Form.
3) TextBox1 = Username TextBox2 = Password
4) One clicks the "Log In" button.
5) HERE is the problem. I do not know how to check if the specific username and the password are correct. I have a file called "Users.dat". In there every valid Username(marked with a *) and it's Password(marked with a #) is contained e.g.*Username#Password.
I want my "Log In" program to check if the Username matches one of the usernames and if the username is found in the file, if the password provided is the same as the one standing behind the Username in the file.
6) If both the Username and Password are valid, the Chat Programs shows up.
I want to be able to read and write the process memory of Firefox for a game on facebook(It's kind of like cheating only you can't cheat, nothing stays permanent.) this is just for fun. The game is called happy fish aquarium and you raise fish in the game and it's just really addicting. I found a program that reads process memory and lets me change certain values in happy fish aquarium so I can make my fish tank look different or whatever. But if I reload the page it will of course go back to the original state because the fish tank's memory is held online. The point is, I just want to make a program that can read the process memory from Firefox from a certain range and bytes. like 4 bytes and a range of 00400000 to 7FFFFFFF. Does anyone know how I can achieve this? Please note, this is not for cheating purposes in any way whatsoever, it's simply for visual fun(visual meaning only I can see it). What I want to do is the same as using the add-on firebug in firefox to change the html on a webpage.
View 10 RepliesI am having a problem with my program that is desinged to read a 3rd party text file database. I posted previosuly about a problem inserting an item in a new row and the column was expectig a different data type. It appears that sometimes the column is being determined to be of decimal value, I dont understand why. the fields contain information such as
Col1
F123456
CLW-12321 etc....
So my column fills with
123456
12321 the letters just get chopped off
So I added MaxScanRows = 0 to my schema file and that took care of the problem
Except now several of my columns that contain Date Values are coming back
9/24/2010 00:00:00
without the setting MaxScanRows = 0
The date returned 9/24/2010
Here is the code for my schema ini file I am creating:
HTML
Dim fs As New FileStream("Schema.ini", FileMode.Create, FileAccess.Write)
Dim writer As New StreamWriter(fs)
[CODE]............
I have been trying different settings hence the dimmed out lines
Here is the code to fill the datatable:
HTML
[CODE].............
I am thinking that without the MaxScanRows = 0 setting the datatype for Col1 is being incorrectly determined
I am not sure what is happening with other columns that contain date values. Apparently If i use MaxScan Rows=0 all columns are being pulled over as string value which creates numerous problems. If I dont use maxscanrows then all columns appear to be correct except Col21 MLSNUM which is being pulled in as a decimal. Can I change that in the schema file?
