easiest way to input an entire text file...

[crptcblade]

Can somebody give me a handle on it?

Thanks

Try this.

bool OpenFile(LPSTR sFileName, HWND hText) {
	HANDLE hFile;
	bool bSuccess;
	LPSTR pszText;
	DWORD dwLength;
	DWORD dwRead;

	hFile = CreateFile(sFileName, GENERIC_READ, NULL, NULL, OPEN_EXISTING, 
		FILE_ATTRIBUTE_NORMAL, NULL);

	if ( !hFile ) 
		return false;
	
	dwLength = GetFileSize(hFile, NULL);
	
	if(dwLength != 0xFFFF)
	{
		pszText = (char *)LocalAlloc(LPTR, dwLength + 1);
		if (ReadFile(hFile, pszText, dwLength, &dwRead, NULL)) 
		{
			pszText[dwLength] = 0; 
			if( SetWindowText(hText, (LPCTSTR) pszText)) {
				bSuccess = true;
			}
		}
		LocalFree((HLOCAL) pszText);
	}
	else
	{
		MessageBox(NULL, "File cannot exceed 65535 bytes", "Error", MB_OK | MB_ICONEXCLAMATION);
		bSuccess = false;
	}

	CloseHandle(hFile);
	return bSuccess;
}

Usage:

OpenFile("FileName", hwndEdit);

file handle, eh? how about a file pointer...

#include <time.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>

void main( void )
{
   FILE *fptr;
   struct _stat buf;
   int i;
   char fnam[] = "myfile.txt";
   i =  _stat( fnam, &buf );  // get file information
   // buf.st_size is now file len
   char *filebuf = malloc(buf.st_size);  // get a place to store file in memory
   // check for malloc fail in good code
   fptr = fopen(buffer);
   if ( fread(filebuf, (size_t) buf.st_size, (size_t) buf.st_size, fptr) == buf.st_size)   // read it all in
   {
      printf("%s\n","success");
    }
    free(filebuf);
    fclose(fptr);   
 }
