File creation error. File disappears after app close!!!

[xandaz]

    I have this code:

Code Select Expand

.elseif ax==IDM_SAVE
       
            push    hInstance
            pop     gofn.hInstance
            push    hMainWindow
            pop     gofn.hWndOwner
            mov     gofn.lpstrFilter,offset ProjectFilter
            mov     gofn.lpstrTitle,offset szSaveProject
            invoke  GetSaveFileName,addr gofn
            or      eax,eax
            jz      end_save
            invoke  SetWindowText,hWnd,gofn.lpstrFileTitle
            invoke  CreateFile,gofn.lpstrFile,GENERIC_READ+GENERIC_WRITE,\
                        FILE_SHARE_READ+FILE_SHARE_WRITE,0,CREATE_NEW+\
                        OPEN_EXISTING,FILE_ATTRIBUTE_ARCHIVE+FILE_ATTRIBUTE_NORMAL,\
                        0
             mov     hProject,eax
             invoke  BuildProjectFile,hWnd
             invoke  CountBytes,addr ProjectFileBuffer                                   
             invoke  WriteFile,hProject,addr ProjectFileBuffer,ecx,\
                        addr noBytesWritten,0
             invoke  CloseHandle,hProject


    When i go back to load the file it isnt there... what is it? any ideas. Thanks in advance

Hello,

Try to simplify your CreateFile parameters. Here is how I use it :

Code Select Expand

    xor     ebx,ebx
    invoke  CreateFile,pFileName,GENERIC_WRITE,\
            ebx,ebx,CREATE_ALWAYS,ebx,ebx

   ok....it's not a binary value and cant be combinated. thanks

[xandaz]

   Thanks Vortex but it didn'r work. File disappears after the app is closed. thanks anyway

Hi xandaz,

Code Select Expand

             invoke  WriteFile,hProject,addr ProjectFileBuffer,ecx,\
                        addr noBytesWritten,0

Code Select Expand

BOOL WriteFile(
  HANDLE       hFile,
  LPCVOID      lpBuffer,
  DWORD        nNumberOfBytesToWrite,
  LPDWORD      lpNumberOfBytesWritten,
  LPOVERLAPPED lpOverlapped
);

nNumberOfBytesToWrite is ecx in your case but what happened to this register?

[jj2007]

Windows has a wonderful function called GetLastError. Strongly recommended!

[xandaz]

    Vortex. the bytes have been counted by a procedure and result is in ecx. It works. I open the file and there's the data just the way it should be. It's when i close the app that file disappears. Thanks a lot.

Hi xandaz!

Here application crash when closing, the file remain perfectly.

Code Select Expand


    .if     uMsg==WM_DESTROY
quit:   
        invoke  CloseHandle,hProject

In theory this hProject is alredy closed ¿?

[xandaz]

it keeps on. when i close the app the created files disappear. i need some help pls. thanks in advance

[felipe]

try not using the FILE_ATTRIBUTE_ARCHIVE flag 

[xandaz]

   i tried that. doesn't work either. all files created during the app run time disappear when app closes. thanks anyway

[xandaz]

   no HSE.... the hProject handle gets freed at WM_DESTROY.

[jj2007]

This can go on for weeks... unless you post complete code, of course.

[xandaz]

   you said it yourself.... i need a new approach to coding JJ. I have here a mix of Unicode and ANSI proceedings that are killing me.
