List Box DBLCLK event & reading file contents

[Suresh.hc]

Hello all,

I have List Box and rich edit box in my Dialog IDC_SLIST & IDC_FILECONT

List Box contains the text file names , When the user double click on the list box that file content should be displayed in the rich edit box.

Can u please tell me what all the changes I have to make and how to do the double click event in win 32 Api application ??


case WM_COMMAND:
switch(LOWORD(wParam))
{
case LBN_DBLCLK:
{
HWND hwndListBox = GetDlgItem(hwnd, IDC_SLIST);
int iCurSel =::SendMessage(hwndListBox,LB_GETCURSEL,0,0);
TCHAR FName[30];
SendMessage(hwndListBox,LB_GETTEXT,(WPARAM)iCurSel,(LPARAM)FName);


CStdioFile file(FName, CFile::modeRead);
DWORD dwSize = file.GetLength();
char *pBuffer = new char[dwSize + 1];
UINT uRead = file.Read(pBuffer, dwSize);
pBuffer[uRead] = '\0';
file.Close();


HWND hwndRichEdit = GetDlgItem(hwnd, IDC_FILECONT);
::SendMessage(hwndRichEdit,WM_SETTEXT, 0,(WPARAM)pBuffer);
delete [] pBuffer;
}

-----------
this code works in MFC but its not working in win 32 api, i am not able to use CFile what has to be done ??

CStdioFile file(FName, CFile::modeRead);
DWORD dwSize = file.GetLength();
char *pBuffer = new char[dwSize + 1];
UINT uRead = file.Read(pBuffer, dwSize);
pBuffer[uRead] = '\0';
file.Close();

Thanking you,

humpty i am using Win 32 Application and VC++6

[humptydumpty]

Then Instead of CFIle Simply use CreateFile and ReadFile and WriteFile Method

have alook on the Following Link to Understand Difference between MFC and WIn32 FILE IO
