Thread: Save, NOT save as

I have these functions for opening and "Save As"ing files, but how would I create a function that, if it has already been saved, saves it without a dialog box, and if it hasn't been saved, open the save as dialog box? Thanks !

Code:

BOOL LoadTextFileToEdit(HWND hEdit, LPCTSTR pszFileName) {
 HANDLE hFile;
 BOOL bSuccess = FALSE;
 hFile = CreateFile(pszFileName, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, NULL);
 if(hFile != INVALID_HANDLE_VALUE) {
  DWORD dwFileSize;
  dwFileSize = GetFileSize(hFile, NULL);
  if(dwFileSize != 0xFFFFFFFF) {
   LPSTR pszFileText;
   pszFileText = GlobalAlloc(GPTR, dwFileSize + 1);
   if(pszFileText != NULL) {
    DWORD dwRead;
    if(ReadFile(hFile, pszFileText, dwFileSize, &dwRead, NULL)) {
     pszFileText[dwFileSize] = 0;
     if(SetWindowText(hEdit, pszFileText)) {
      bSuccess = TRUE;
     }
    }
    GlobalFree(pszFileText);
   }
  }
  CloseHandle(hFile);
 }
 return bSuccess;
}

BOOL SaveAsTextFileFromEdit(HWND hEdit, LPCTSTR pszFileName) {
 HANDLE hFile;
 BOOL bSuccess = FALSE;
 hFile = CreateFile(pszFileName, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
 if(hFile != INVALID_HANDLE_VALUE) {
  DWORD dwTextLength;
  dwTextLength = GetWindowTextLength(hEdit);
  if(dwTextLength > 0) {
   LPSTR pszText;
   DWORD dwBufferSize = dwTextLength + 1;
   pszText = GlobalAlloc(GPTR, dwBufferSize);
   if(pszText != NULL) {
    if(GetWindowText(hEdit, pszText, dwBufferSize)) {
     DWORD dwWritten;
     if(WriteFile(hFile, pszText, dwTextLength, &dwWritten, NULL)) {
     bSuccess = TRUE;
     }
    }
    GlobalFree(pszText);
   }
  }
  CloseHandle(hFile);
 }
 return bSuccess;
}

// BOOL SaveTextFileFromEdit(HWND hEdit, LPCTSTR pszFileName) {} // Heres what i want

void DoFileOpen(HWND hwnd) {
 OPENFILENAME ofn;
 char szFileName[MAX_PATH] = "";
 ZeroMemory(&ofn, sizeof(ofn));
 ofn.lStructSize = sizeof(ofn);
 ofn.hwndOwner = hwnd;
 ofn.lpstrFilter = "Text Files (*.txt)\0*.txt\0HTML File (*.html)\0*.html\0Cascading Style Sheet (*.css)\0*.css\0XML Document (*.xml)\0*.xml\0XSL StyleSheet (*.xsl)\0*.xsl\0PERL Source Code (*.pl)\0*.pl\0PHP Source Code (*.php)\0*.php\0C Source Code File (*.c)\0*.c\0C++ Source Code File (*.cpp)\0*.cpp\0C/C++ Header File (*.h)\0*.h\0Java Source Code (*.java)\0*.java\0Pascal Source Code (*.pas)\0*.pas\0All Files (*.*)\0*.*\0";
 ofn.lpstrFile = szFileName;
 ofn.nMaxFile = MAX_PATH;
 ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
 ofn.lpstrDefExt = "txt";
 if(GetOpenFileName(&ofn)) {
  HWND hEdit = GetDlgItem(hwnd, ID_CHILD_EDIT);
  if(LoadTextFileToEdit(hEdit, szFileName)) {
   SetWindowText(hwnd, szFileName);
  }
 }
}

// void DoFileSave(HWND hwnd) {} //heres what i want

void DoFileSaveAs(HWND hwnd) {
 OPENFILENAME ofn;
 char szFileName[MAX_PATH] = "";
 ZeroMemory(&ofn, sizeof(ofn));
 ofn.lStructSize = sizeof(ofn);

 if(GetSaveFileName(&ofn)) {
  HWND hEdit = GetDlgItem(hwnd, ID_CHILD_EDIT);
  if(SaveAsTextFileFromEdit(hEdit, szFileName)) {
   SetWindowText(hwnd, szFileName);
  }
 }
}

Are those real functions? Or are you using that as an example of what to do? Thanks !

_access is real, the others are examples.

What does it do?
