I need a help with iText in C#. I'm trying to extract a table from a PDF file and save this into a new CSV file, keeping the values in the correct places. For this, I thought the solution was to create a two-dimensional array to organize the data.
Extracting all information from PDF with iText, I saw it was possible to get some numerical data that seemed to be the position of a piece of text on the page and I organized my array based these indexes. It didn’t work, the text was completely dispersed in various different cells. Now, I want to know what this values means, because they don't follow a "correct" order and I want to know if is possible to organize the future table with this.
I'm using ";" as delimiter cell.
For testing, I'm using this PDF
http://www.americana.sp.gov.br/americanaV5/download/contasPublicas/Despesa_Categoria_Economica_2014.pdf
Here's my code:
protected void Button2_Click(object sender, EventArgs e)

string[] linhas = (Encoding.UTF8.GetString(Encoding.Convert(Encoding.Default, Encoding.UTF8, leitorp.GetPageContent(i)))).Split('\n');

I am trying to display points from 7 files. Each file corresponds to a day, and I am trying to add a button where it takes the last 7 created files and displays them as x=dateTime and y= value. what this code currently does is that only displays the x axis on the left and right side.

I know its somewhere in the Xaxis interval type part,but I don't know what values to put in.

I want to search some lines containing some specific data and store these data in a list, how can I do this? I have written this code for my project, but this code can only find and store the first line containing my wanted data because all these lines are started with the same structure, for an example, my data is repeated in lines 100, 250, 400, 660, and all these lines are stated with "|PROD |OIL |" .
double[] oil_prdc = new double[10];

Example of how to read a file:
try
{
// Create an instance of StreamReader to read from a file.
// The using statement also closes the StreamReader.
using (StreamReader sr = new StreamReader("TestFile.txt"))
{
string line;
// Read and display lines from the file until the end of
// the file is reached.
while ((line = sr.ReadLine()) != null)
{
Console.WriteLine(line);
}
}
}
catch (Exception e)
{
// Let the user know what went wrong.
Console.WriteLine("The file could not be read:");
Console.WriteLine(e.Message);
}
Search for specific text in each "line":
public static string getBetween(string strSource, string strStart, string strEnd)
{
int Start, End;
if (strSource.Contains(strStart) && strSource.Contains(strEnd))
{
Start = strSource.IndexOf(strStart, 0) + strStart.Length;
End = strSource.IndexOf(strEnd, Start);
return strSource.Substring(Start, End - Start);
}
else
{
return "";
}
}
How to use it:
string text = "This is an example string and my data is here";
string data = getBetween(text, "my", "is");

how can i read and write in the same time from two opened forms?
I have a combobox outside my tabcontrol. In each tab control there is a datagridview full of values. In the combobox you can choose a conversion for all values. For example eV→meV.
When i am in the first tab and use the combobox there are no problems, but after i switch the tab and then wanna use the combobox the program list down however the whole combobox is full of try/catch

Accept these answer if you dont know how to post your own answer?.
Answer:
Problem fixed. The reason was the dgv.autosizemode , when i deactivate it before the conversions it runs.
for (int Spalte = 0; Spalte < Anzahl; Spalte++)
{
DGV[Spalte].AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.None;
for (int i = 0; i < counter[Spalte]; i++)
{
DGV[Spalte][0, i].Value = meV[Spalte][i];
}
DGV[Spalte].AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells;
}
I made a simple file binary encrypt/decrypt and it works perfectly for any text document.
But when I encrypt and decrypt image / word document file, the file corrupt.
I don't understand why this happen.
This is my code to get the file byte array.
byte[] b = null;
using (System.IO.FileStream fr = new System.IO.FileStream(this.txtFile.Text, System.IO.FileMode.Open))
{
using (System.IO.BinaryReader br = new System.IO.BinaryReader(fr))
{
b = br.ReadBytes((int)fr.Length);
}
}
And this is how I write all the bytes back.
System.IO.File.WriteAllBytes(filepath, b);
Can someone explain to me why?
Edit : This is my Encrypt/Decrypt code.
Sorry if its messy, I'm new to cryptograph.
for (int i = 0; i < b.Length; i++)
{
if (keyIndex >= key.Length)
{
keyIndex = 0;
}
string fileBIN = Convert.ToString(b[i], 2);
string keyBIN = Convert.ToString(Convert.ToInt32(Convert.ToChar(key[keyIndex])), 2);
string newBIN = string.Empty;
keyIndex += 1;
if (fileBIN.Length > keyBIN.Length)
{
for (int x = 0; x < Math.Abs(fileBIN.Length - keyBIN.Length); x++) { keyBIN = "0" + keyBIN; x -= 1; }
}
else
{
for (int x = 0; x < Math.Abs(fileBIN.Length - keyBIN.Length); x++) { fileBIN = "0" + fileBIN; x -= 1; }
}
if (fileBIN == keyBIN)
{
newBIN = fileBIN;
}
else
{
for (int x = 0; x < fileBIN.Length; x++)
{
if (fileBIN.Substring(x, 1).ToString() == keyBIN.Substring(x, 1).ToString()) { newBIN += "0"; }
else { newBIN += "1"; }
}
}
b[i] = Convert.ToByte(newBIN, 2);
}
