DoFileOpenSave? HELP PLEASE!

I have the code:

BOOL LoadFile(HWND hEdit, LPSTR pszFileName)
{
HANDLE hFile;
BOOL bSuccess = FALSE;

hFile = CreateFile(pszFileName, GENERIC_READ, FILE_SHARE_READ, NULL,
OPEN_EXISTING, 0, 0);
if(hFile != INVALID_HANDLE_VALUE)
{
DWORD dwFileSize;
dwFileSize = GetFileSize(hFile, NULL);
if(dwFileSize != 0xFFFFFFFF)
{
LPSTR pszFileText;
pszFileText = (LPSTR)GlobalAlloc(GPTR, dwFileSize + 1);
if(pszFileText != NULL)
{
DWORD dwRead;
if(ReadFile(hFile, pszFileText, dwFileSize, &dwRead, NULL))
{
pszFileText[dwFileSize] = 0; // Null terminator
if(SetWindowText(hEdit, pszFileText))
bSuccess = TRUE; // It worked!
}
GlobalFree(pszFileText);
}
}
CloseHandle(hFile);
}
return bSuccess;
}

BOOL SaveFile(HWND hEdit, LPSTR pszFileName)
{
HANDLE hFile;
BOOL bSuccess = FALSE;

hFile = CreateFile(pszFileName, GENERIC_WRITE, 0, 0,
CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, 0);
if(hFile != INVALID_HANDLE_VALUE)
{
DWORD dwTextLength;
dwTextLength = GetWindowTextLength(hEdit);
if(dwTextLength > 0)// No need to bother if there's no text.
{
LPSTR pszText;
pszText = (LPSTR)GlobalAlloc(GPTR, dwTextLength + 1);
if(pszText != NULL)
{
if(GetWindowText(hEdit, pszText, dwTextLength + 1))
{
DWORD dwWritten;
if(WriteFile(hFile, pszText, dwTextLength, &dwWritten, NULL))
bSuccess = TRUE;
}
GlobalFree(pszText);
}
}
CloseHandle(hFile);
}
return bSuccess;
}

BOOL DoFileOpenSave(HWND hwnd, BOOL bSave)
{
OPENFILENAME ofn;
char szFileName[MAX_PATH];

ZeroMemory(&ofn, sizeof(ofn));
szFileName[0] = 0;

ofn.lStructSize = sizeof(ofn);
ofn.hwndOwner = hwnd;
ofn.lpstrFilter = "HTML (*.htm)\0*.htm\0All Files (*.*)\0*.*\0\0";
ofn.lpstrFile = szFileName;
ofn.nMaxFile = MAX_PATH;
ofn.lpstrDefExt = "htm";

if(bSave)
{
ofn.Flags = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY |
OFN_OVERWRITEPROMPT;

if(GetSaveFileName(&ofn))
{
if(!SaveFile(GetDlgItem(hwnd, IDC_MAIN_TEXT), szFileName))
{
MessageBox(hwnd, "Save file failed.", "Error",
MB_OK | MB_ICONEXCLAMATION);
return FALSE;
}
}
}
else
{
ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
if(GetOpenFileName(&ofn))
{
if(!LoadFile(GetDlgItem(hwnd, IDC_MAIN_TEXT), szFileName))
{
MessageBox(hwnd, "Load of file failed.", "Error",
MB_OK | MB_ICONEXCLAMATION);
return FALSE;
}
}
}
return TRUE;
}

I also have:

case CM_FILE_OPEN:

DoFileOpenSave(hwnd, FALSE);

break;

When it runs, I do FILE -> OPEN, but it says Load of File Failed. What is the correct code to load and save HTML files?

I tried your code and it worked ok, try stepping through it with a debugger to find out where your LoadFile() function is failing.

I think you also need to use

GlobalFree(GlobalHandle(pzText));

Do some validation of the free return to see.
ie

Code:

---

HGLOBAL hMem;
hMem=GlobalFree(GlobalHandle(pzText));
if(hMem!=NULL)
{
    //error (use GetLastError, sprintf and Messagebox)
}
else pzText=NULL;

---

This is so you can always test the mem == NULL for alloc's ect.
