Extracting Text from Multiline Edit Box

Having troubles handling text from a multiline edit box.. the first part of this algorithm runs fine by itself.. the second part (highlighted in blue) runs fine as a DOS project.. but when I add it to this windows project.. it distorts the GUI display and causes the program to terminate...

Code:

void EditBoxFileParser(HDC hdc, PAINTSTRUCT* ps, HFONT hFont, HWND hwnd, HWND hEdit)
{
     
     int iCount; 
     WORD iLength, iOffset;        
     TCHAR **Lines;
     
     //Get Number of Lines in Edit Field
     iCount = SendMessage(hEdit, EM_GETLINECOUNT, 0, 0);
     
     //If Editbox is empty, exit function
     if(!iCount)
     
          return;
     
     Lines = new TCHAR*[iCount];
     
     //Populate 2D array, Lines[LineIndex][LineText]
     for(int i=0; i<iCount; i++)
     {    iOffset = SendMessage(hEdit, EM_LINEINDEX, i, 0);
          iLength = (WORD)SendMessage(hEdit, EM_LINELENGTH, iOffset, 0);
          Lines[i] = new TCHAR[iLength+sizeof(WORD)+1];
          CopyMemory(Lines[i], &iLength, sizeof(WORD));          
          SendMessage(hEdit, EM_GETLINE, i, (LPARAM)Lines[i]);
          Lines[i][iLength] = '\0';
     }   
     
     //Visually Verify Lines[][]
     for(int i=0, x=300, y=275; i<iCount; i++)
          
             TextOut(hdc, x, y+=20, Lines[i], lstrlen(Lines[i]));   

     
/* Code works fine up until this point */

//The code below works fine by itself in as a DOS application
//But locks up this windows project
 
    //Parse User Entered Text
    TCHAR **Name = new TCHAR*[iCount];
    TCHAR **FiberCount1 = new TCHAR*[iCount];
    TCHAR **FiberCount2 = new TCHAR*[iCount];;
    int word_index;
    bool cont = true;
    
    for(int i=0, j=0; i<iCount; i++, j=0)
    {   
        word_index = 0;
	cont = true;
        
        do{        
         
              //Extract Fiber Name
              while(Lines[i][j]!=',')
              {
                   j++;
              }
         
              Lines[i][j]='\0';
              Name[i] = new TCHAR[j-word_index+1];
              lstrcpy(Name[i], Lines[i]+word_index);
              Name[i][j-word_index] = '\0';
         
              word_index = j;
	      word_index++;
         
              //Extract Beginning Fiber Count
              while(Lines[i][j]!='-')
              {
                   j++;
              }
         
              Lines[i][j] = '\0';
              FiberCount1[i] = new TCHAR[j-word_index+1];
              lstrcpy(FiberCount1[i], Lines[i]+word_index); 
              FiberCount1[i][j-word_index] = '\0';
         
              word_index = j;
	      word_index++;
         
              //Extract Ending Fiber Count
              while(Lines[i][j]!=',' && Lines[i][j]!='\0')  
              {
                   j++; 
              }

	      if(Lines[i][j]=='\0')

	           cont = false;
         
              Lines[i][j] = '\0';

	      word_index++;
         
          }while(cont);  
                 
    }   
    
    //Visual Verification
     for(int i=0, x=400, y=275; i<iCount; i++)
          
             TextOut(hdc, x, y+=20, Name[i], lstrlen(Lines[i]));  
        
}

Your parsing code is a little convoluted and has many possible ways that it can crash. How about replacing it with good use of the sscanf function. Something like this:

Code:

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

struct Fiber
{
	TCHAR Name[100];
	int   Count1;
	int   Count2;

	Fiber()
	{
		Name[0] = Count1 = Count2 = 0;
	}
};

int main()
{
	char* Lines[] = {{"H1001, 1-24"}, {"A, 25-36"}, {"H1007, 36-45"}};
	int   iCount  = 3;

	Fiber* Fibers = new Fiber[iCount];

	for (int i = 0; i < iCount; i++)
	{
		if (_stscanf(Lines[i], TEXT("%99[^,], %d-%d"),
		              Fibers[i].Name, &Fibers[i].Count1, &Fibers[i].Count2) != 3)
		{
			printf("Invalid line: %s\n", Lines[i]);
		}

		// Check for correct parsing...
		printf("%s--%d--%d--\n", Fibers[i].Name, Fibers[i].Count1, Fibers[i].Count2);
	}

	getchar();
}
