Solved: Character Reading problem with ReadFile()

[MattKent]

I've figured it out. It was quite obvious really; use chars instead of DWORDS. Thanks for anyone who looked anyway.


Hi,

I've been having trouble with this for the past 48 hours. I hope someone can point me in the right direction. Basically I have a text file of characters. I want to read this into the program, but it's a Windows program so I'm using the open file dialogue.

Everything goes fine; I gain a handle from the dialogue; I use read file and populate a buffer with the characters (in theory) and for testing purposes I output this value to a status bar on the program.

Only I find that the buffer is populated with every fourth value from the string, e.g:

2459674835137 stores in the buffer positions [0-3] as 2, 6, 3, 7.

Here is the code in WinMain which takes the value and sends to status bar:

	wchar_t myword [2] = { 'H','\0' };	
	DWORD temp = 0;
	temp = DataM.OpenReadFile(hWnd, message, wParam, lParam);
	myword[0] = (char)temp;
	SendMessage((HWND) StatusBar,(UINT) SB_SETTEXT, (INT) 0, (LPARAM)myword);

And this is function involved (DataM.OpenRead File):

	DWORD DataManager::OpenReadFile(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam){
	HANDLE fileHndl = UIHandle.OpenFile(hWnd, message, wParam, lParam);
	DWORD dwBuffer[256];
	DWORD dwNumRead;
	ReadFile(fileHndl, dwBuffer, sizeof(int)*256, &dwNumRead, NULL);
	DWORD result;
	
	/*for(int i=0; i<256; i++){
		if((wchar_t)dwBuffer[i] == '2'){
			//result = (wchar_t)dwBuffer[i];
			result = 'Z';
			break;
		}
	}*/

	result = dwBuffer[0];

	return result;
  }

So can anybody suggest why only 3 quarters of the characters are being extracted? Also what can be done to get around this?
Any help whatsover would be extremely appreciated.

Thank you very much in advance.
