I wish did fix the issue. I have a .txt file that's something like this: , This returns all lines, which have the required condition:
code :
string productcode = "productCode1";
string id = "5270";

var result = System.IO.File.ReadAllLines(@"c:\file.txt")
                   .Select(x => x.Split('|'))
                   .Where(x => x.First() == id && x.Any(y => y == productcode));

I wish this help you Your xml seems to be well formed. Are you using a handler and parser class to get xml tag contents? Probably best method to reach it. You can find some good examples on internet or other posts. Please take a look to following one, same method that I am using successfuly

Hope this helps Your current code is only iterating to the ScriptFile level. I suspect the simplest approach would be:
code :
var warnings = doc.Descendants("SqlEyeWarning")
                  .Select(x => new {
                      FileName = (string) x.Parent.Parent.Attribute("Name"),
                      Message = (string) x.Attribute("message")
var warnings = doc.Root
                  .Select(x => new {
                      FileName = (string) x.Parent.Parent.Attribute("Name"),
                      Message = (string) x.Attribute("message")

Difficulty reading binary files in c++

fixed the issue. Will look into that further I have a visual c++ project named Search Elements in which there is a class called PeriodicTable and I have another visual c++ project called Write Elements in which there is this same class and it's description(variable names and their sizes) is same too... , It perfectly works for me with the following read code:
code :
int Read()
    ifstream file;
    file.open("PeriodicTable.dat", ios::binary | ios::in);

    while (0 == file.rdstate())
      PeriodicTable ptele;
      file.read((char *)&ptele, sizeof(ptele));
      //if (0 == file.rdstate())
      //    ptele.PrintInfo();

    return 0;

difficulty with reading the last record from a .txt file in C

help you fix your problem If the position to read the record by fseek, Record must be a fixed length.
code :
void append(void){
    FILE *fp=fopen("pre-survey.txt", "a");
    scanf("%19s", temp.name);
    scanf("%d", &temp.q1);
    scanf("%d", &temp.q2);
    scanf("%d", &temp. q3);
    //32bit system MAX_INT : 2147483647 (10digits)
    //19char  2digit 2digit 2digit\n total:30 (windows:31(\n->CRLF)
    fprintf(fp, "%-20s%3d%3d%3d\n", temp.name, temp.q1, temp.q2, temp.q3);

void last_record(void){
    FILE *fp=fopen("pre-survey.txt", "rb");
    //fseek(fp, -31, SEEK_END);//for windows
    fseek(fp, -30, SEEK_END);
    fscanf(fp, "%s %d %d %d", get.name, &get.q1, &get.q2, &get.q3);
    printf("name: %s\n", get.name);
    printf("q1: %d\n", get.q1);
    printf("q2: %d\n", get.q2);
    printf("q3: %d\n", get.q3);

like below fixes the issue First of all, without taking a further look at the rest of the code, the first three bytes of your global received_data will never be written. Take a look into this particular part of your advertisementCallback():
