I am getting different behaviour now, but still not what I am expecting :(

Now I am getting "55525" in both cases

Use stringstream::str() instead of ignore() .

I.e.

ss.str(""); // clear the buffer

By body modifications I mean facial piercings, stretched piercings and tattoos. When I leave university I will have 2x 30mm (1" 1/8) ear lobes, 4mm inner conchs (cartilage in the back of your ear), 10mm septum (fleshy bottom of the nose), snake bites, 2x anti-eyebrows, and 2 sleeves, chest tattoo and a swallow tattoo on my neck.

At the point where you realize that you are scaring little kids away, you may have already lost 'the game'. ;)

Adding to what Ancient Dragon said, you might want to read up on Hungarian Notation, the same topic in Wikipedia with some criticism.

Over time, you'll probably get used to it.

I believe this happens due to a typo; Theading vs. Threading .

Have you tried posting at HP Support Forum?

Trying to get rid of the various C/C++ runtime versions you have installed, is not a good idea, since likely quite a lot of software you've got installed depend on them.

You might try the Code::Blocks' forums.

I was testing the marking of the first unused record so that later I can return the read values to main function for processing (search/filter, sort, add/delete)

In case you do read MAXDATA records, contacts[i].first_name[0] = '\0'; will be an out-of-bounds write.

string lives in the std namespace, so e.g. std::string input; ought to work.

what i have done wrong?

To get you started, delete line 138.

In your implementation file you have forgotten

void InsertionSort::insertionsort(long theArray[], int n)

I keep getting values

like

0x1ea91250
0x1ea911f0
0x1ea91190
0x1ea91130

You are printing the pointers' values -- dereferencing (*) will fix this, i.e.

std::cout << * temp->objectData  << std::endl;

This would put the whole code in that file(1.c) as it is to this file(2.c).

Yes, hence your 2.c will turn into ..

static int y=23;
void abc(int a){
 printf("%d\n",a);
 }
int main(){
 abc(12);
 printf("\n");
 printf("%d\n",y);
 return 0;
}

giving you a file-scope variable y perfectly accessible everywhere in 2.c but not in any other file -- does this make things any clearer?

>> So, how is this static variable in 1.c printed here??

What happens when the preprocessor processes your #include "1.c" directive that you have in 2.c ?

You could have a look at a tutorial - Switch statements

>> it gives me the output of *** but i cannot connect it to my password ( 123)

You'll probably find this post enlightening.

>> why this doesn't work correctly?

The input stream has the skipws format flag set, use noskipws to clear the flag.

I just did a ctrl+f in notepad when I opened the .lib file and it couldn't find the text 'KeyValue' would this mean they're not being exported?

No.

Rather use dumpbin, see its /LINKERMEMBER option.

You are given two integer numbers: the base a (0 <= a <= 20) and the index b (0 <= b <= 2,147,483,000).

...
if(a!=0 || b!=0)
{
...

What will your program do when both a AND b are zero?

Use comparison ( == ) instead of assignment ( = ) in your if-statements.

... the file fails to open.

perror() is likely to be informative in this case.

but I get an assertion failure, "string iterators are incompatible"

Are you really sure that std::find_if(...) is failing? I'd imagine that the next line (35) would cause the failure -- it being invalid at that point.

I did it. Alright, I got it to work with only one loop, but can you tell me why in my output tags2 is reading 18 data sets when it is only supposed read 10.

Hint: 8 + 10 = 18

I just tried making the routine have a return value and no args and it works.
Then I tried adding in one argument and it fails, so it looks like the problem is with the arguments, not the return value.

This suggests mismatched calling conventions (C# is assuming Stdcall, whereas your export is Cdecl).

The following import probably works in your case:

[System.Runtime.InteropServices.DllImport("testsub.dll",
  CallingConvention = System.Runtime.InteropServices.CallingConvention.Cdecl)]
  private static extern int addit(int a, int b);

...Here is the code causing the app crash:

string ReadLine()
{
	getline(file, lineread);
	if (lineread.find_first_of("WSF_") != string::npos)
	{
		return lineread;
	}
}

The function is basically badly broken -- what will it 'return' if lineread.find_first_of("WSF_") == string::npos ?

Aren't you getting any compiler warnings?

>> Thread ID of the window (what im currently looking to get

So, if you want to know the window's thread identifier then you could give this a try

#include <windows.h>
#include <tchar.h>

int main()
{
  HWND hW = FindWindow(_T("MSBLWindowClass"), _T("Windows Live Messenger"));

  if(hW != NULL)
  {
    // Process identifier.
    DWORD PID;
    // Thread identifier.
    DWORD TID = GetWindowThreadProcessId(hW, &PID);

    // ... use PID/TID here ... 

  }
}

Note that i is incremented at line 10

m=b[i++];

I believe you are looking for GetWindowThreadProcessId()

Basically, the compiler ends up seeing e.g. triangle_main.cpp (roughly) as follows

class Triangle
{
public:
  Triangle( double, double, double ) ; //constructor initializing the 3 triangle dimensions
  void calculateDimensions( double, double, double ) ; //assigns dimensions
  //int getTriangle( ) ; //get the value of the dimensions  
  void printDimensions( double, double, double ) ; //print dimensions
private:
  double side1 ;
  double side2 ;
  double hypotenuse ;

} int main( ) // <--- apparently, this will not work
{
  Triangle rightTriangle( 1.0 , 1.0 , 1.0 ) ; //create Triangle object
  return 0 ;
}

z:\in common folder 24_09\programming\exercises deitel and deitel\ex 5.20 p242\triangle_main.cpp(7) : error C2628: 'Triangle' followed by 'int' is illegal (did you forget a ';'?)

Your compiler is making an 'educated guess' -- you need to terminate the class Triangle definition with a semicolon.

The function "getinput();" is a prototype function.. But prototype functions work wonders.. especially in situations like these!

I'm guessing that triumphost meant to say function prototype

You seem to be missing a semicolon ..

class CGame 
{
   ...

} ; // <--- add semicolon

Can anyone provide me with a link to how to create and read from ini files.

You might read up on the GetPrivateProfile...() and WritePrivateProfile...() functions, see Registry Functions

Include <windows.h>

#include <windows.h>
#include <mysql/mysql.h>

>> That works, to a point. Things got pretty ugly, though, when I added the old ...
>> ... I only want the #define type statements to pre-process, not the #include.

Perhaps you'd like to 'guard' your #include s with #ifdef s, like so ..

// foo.cpp
#ifdef VERNON_COMPILES
#include <iostream>
#endif

int main()
  ...

Pre-processing would be:
g++ -E foo.cpp

and compiling would be:
g++ -D VERNON_COMPILES foo.cpp

Something spotted .. what's up with line #1057

>> There has been an improvement. It runs a few seconds faster ...

Console output is slow, you might simply delete the line

cout << "a " << a << " b " << b << endl;

altogether.

For a very short description of a dialog box procedure, see Dialogs. Especially your usage of DefWindowProc() in a dialog box procedure is a big no-no.

>> The error is:
>> unable to establish existance of the account specified task scheduler.

>> While calling pIPersistFile->Save(NULL, TRUE) method it is throwing an error.

A quick test on XP shows that this error (upon pIPersistFile->Save() ) occurs when either;

• The account name is valid, but the password is NULL
• The account name is invalid i.e. it's a non-existing username

Are you absolutely sure you are using valid username & password?

Note that even if I supply a non-existing username, the task is created and when viewed via the Task Scheduler, the currently logged-on user's name has automagically appeared in the Run As -field (which is quite surprising).

Hmm, I see you've marked this thread as solved, but anyhow ..

>> The prog works - but I want to be sure

This far I've gathered that your program goes like the following ..

WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
  HANDLE ghMutex = CreateMutex(
    NULL,              // default security attributes
    TRUE,              // initially owned
    "AnyName");        // named mutex

  if (GetLastError() != ERROR_ALREADY_EXISTS )
  {
    // I think this is the first instance ...

    try 
    {
      Application->Initialize();
      
      // <snip>

      Application->Run();
    }
    catch (Exception &exception)
    {
      Application->ShowException(&exception);
    }
    CloseHandle(ghMutex);

    return 0;
  }
  else
  {
    // I think this is NOT the first instance ...
    Application->Terminate();
  }
  return 0;
}

To test your program's behaviour, use the below console program, i.e. launch this program first and then begin launching new instances of the main program -- will the instance detection still work?

#include <iostream>
#include <windows.h>

int main()
{
  // Create an event (the name used here must match the name of your mutex)
  HANDLE hEvent = CreateEvent(0, FALSE, FALSE, "AnyName");
  
  if(hEvent)
  {
    std::cout   << "Event handle: " << hEvent << std::endl
                << "Now, start multiple instances of your main program ..." << std::endl
                << "Press Enter to exit.";
    std::cin.get();
    CloseHandle(hEvent);
  }
  else
  {
    std::cout << "Unable to create event, error: " << GetLastError() << std::endl;
  }
}
