int:84 -> PWMH=0x00 , PWML=0x54
int:310 -> PWMH=0x01 , PWML=0x36
int:11588 -> PWMH=0x2D , PWML=0x44
how to do this in C#. Need to connect to Oracle db, take a file from directory then read every line of the file. Lines are like this:
123234847656|8800359898818177|A|20130401 14:51:42|
123234847212||D|20130401 14:52:08|
123234847212||M|20130401 14:55:38|
Then will split as string on every '|' char and according to this flag |A|, |D| or |M| I will add/delete/modify information inside. I have trouble with this part with the connection and read/split file and check for the flag A, D or M.
I've a code which reads the Spotify windows in order to get current song playing. The output is:

I was attempting something weired with address to move data around when I discovered that the size of the array is not what I expected. I am passing this structure as &Users to a function that declares it as a void *, then I can deal with chunks of data (memmove) and not have to worry about index or things like that. However...sizeof is returning something I do not understand.
Code:
int i12 = 1001;
cout << i12 << " " << &i12 << endl;
gives the result: 0x7fff0d065098
It's 6 bytes, but I'd expect the address to be 8 bytes on my 64 bit machine. I am using Ubuntu 12.04, GNU compiler.
So, why the address is 6 bytes and not 8 bytes?
How to create text file in C programming. And after some changing in that text file off the running code of C, I want to read that modified text file back in C running code. e.g
Created file may have number 1, after changing this value to 2 let say, than I want to read that 2 value which is in text file.
I'm using the Split method to parse line in a csv file. The following code works if there are no commas in the text of my data.
string csvLine;
string[] splitLine;
csvLine = "Jim Borland,1234,Never dreams in code";
splitLine = csvLine.Split(',');
But if I have commas in the some of the text as below I get then wrong output. So I need split on a commas which are not enclosed in double quotes.
string csvLine;
string[] splitLine;
csvLine = ""Jim,C,Borland",1234,"Never dreams in code"";
splitLine = csvLine.Split(',');
The output I want is:
Jim,C,Borland
1234
Never dreams in code
I found this :
If your strings are all well-formed it is possible with the following regular expression:
String[] res = str.split(",(?=([^"]|"[^"]*")*$)");
The expression ensures that a split occurs only at commas which are followed by an even (or zero) number of quotes ... and thus not inside such quotes).
Nevertheless, it may be easier to use a simple non-regex parser.
But the .split gives me an error and .Split doesn't work either.
I am encoding some information in a binary file, and I want to check what I am doing by printing out all the bytes that represent the file.
This is being done by opening a pointer to the file with fopen, reading in each byte of data as a char, and then writing this char to the screen.
I have some image files (e.g. "image.jpg"), whose structure I know, so that I can test my program.
When I print out the chars, they are initially correct, and follow the structure of the file as expected.
However, after about 40 bytes, I find that every subsequent character is ' ' i.e. a blank character.
I then created a CharToBin function, which allows me to print out the actual bits in the char. When doing this, it shows that all the bits are 1 for the characters. i.e. most of the file is represented by 1's, which is clearly not correct.
This happens on all the image files I have tested, and furthermore, on several other non-image files. They all start printing out ' ' after a while. However, all these files are fine and not corrupted, e.g. the image files display correctly.
Code:
#include <fstream>
#include <iostream>
#include <sstring>
#include <string>
#include <stdio.h>
using namespace std;
string CharToBin(char ch) {
bool bits[8];
for (int i = 0; i < 8; i++)
[Code] ....
while bytesremaining >=8 do something;
if bytesremaing <8 then something else .
I am new and don't know how to code for this.
How to delete certain bytes from middle of a binary file?
Those bytes are in fact of a struct.
One approach I found was to re-write the whole data except the struct I want to delete. But may be its not good one if file size is in gb and I will have to write complete data again.
#include <stdio.h>
#include <stdlib.h>
int main(int argc, int * argv) {
char buffer[16];
FILE *fp;
unsigned long long test;
unsigned char key[16];
fp = fopen("D:key.txt","r");

i searched for a code for reading bytes from a file and i found this one but when i run the program, it doesn't return the bytes written in the file, it returns another bytes / what is the problem?
I am a member of a group still developing the Microprose European Air War game. We have the source code and permission to do this. As the code dates back to 1998 I use Visual Studio 2006.
I have written many programs in Visual basic, and have the following one to read the airbase value in the "targets.dat" file. The file has a four byte header containing the number of tatgets, and a 32 byte data block containing the data for each target.
Private Sub Command1_Click()
List1.Clear
Dim nt As Long
Dim a4() As Long
Open App.Path & " argets.dat" For Binary Access Read As 1
'read and display the number of targets
[Code] ....
Despite many attempts I cannot write the C equivalent of this code into the eaw.exe source. All I really need to know is how to open the 'targets.dat' file and how to get the value of a byte (or integer, or long) at a given position as in the "Get #1, k, a4(n)" line.
I have a flash movie that is bigger than the axShockwaveFlash placeholder that plays it. The axShockwaveFlash placeholder expands to the size of the movie.

How can I make the movie shrink to fit in the axShockwaveFlash placeholder?
I am having difficulty with arrays because of the limitation of the size of the arrays that I can declare. I need sizes that are very large and windows or C# does not allow me to create bigger than the following for example:
public static int[] gaPoints = new int[20000000000000000000 + 1];
I get an error message saying that "integral size is too large".
I need to be able to declare sizes that are even much larger than the abovementioned size.
How can I circumvent this problem?
Do I have to use something other than arrays?
How to read a line with maximum of 8 bytes from a line in a file.
Let say line has 10248 bytes in one single line and same repeats for remaining lines in the file.
I need to read the first 8 bytes of a line and go on read the last 2 bytes of the line and repeat the till end of file.
How I write a 0s or 1s to binary file in bits not in bytes how can i do that ???

View 1 Replies View RelatedI've created a solution who exported Access reports (graphics/tables) to a Word- and a PDF-format. Therefor I use PDFSharp and PDFFocus.
The PDF document is okay. But the Word-document looks good. Only the size of the Word-document, it has to send by e-mail, is much too big (17MB).
I have to open the Word document again to change the PageSettings to be sure, that the page-margins and the print orientation are correct.
using System;
using Microsoft.Office.Interop.Word;
namespace PageSetup {
class TestPageOrientation {
static void Main(string[] args)
[Code] .....
I don't know how it works in the Word-library source. But I've tried WdOrientation.wdOrientPortrait and once I was surprised. I saw this page in Landscape-format.
I think there is something wrong with my document sections, because the documents (with a lot of tables, graphics and a image) is much too big. And that's only after using this method.
So my next question is: How can I shrink the size of this Word document?
And what do I have to do to limit the amount of format-settings in this word-document?
