I am using Visual Basic whxapi2.bas and API I could be doing something wrong. It appears trying to open a file in in-place edit mode still requires that I save it to make changes. I have the following which works to write data from buffer to file. If WHX_OpenEx("C:\Dummy12345.dat", inPlace) = 0 Then MsgBox "Could not open the test file." End If If WHX_Write(Buffer(0), 512) = 0 Then MsgBox "Could not write to the test file." End If Call WHX_Save If I omit "Call WHX_Save" the file remains unchanged. If I include it the changes are written to the file ok. Any ideas, thanks! | ||

In accordance with the program help and the user manual, in in-place mode changes are saved lazily and automatically, at latest when closing the window. Maybe you forgot to close the file. If so, how could WinHex know that it's high time to flush the new file contents to the disk. | ||

Thanks for pointing me to the manual, I know you put a lot of effort in the documentation, but perhaps I should have said I have already included Call WHX_Close after Call WHX_Save Again omitting WHX_Save means the changes are not saved. If it helps,The complete Sub routine is below ---------------------------------------------------------- Sub GotoOffsetReadSector() Dim Buffer(512) As Byte If WHX_Goto(VB2API(512)) = 0 Then MsgBox "Could not go to position", vbCritical, AppName End If Call WHX_Read(Buffer(0), 512) ' {Create a new file with an initial size of 1500000 bytes} If WHX_Create("C:\Dummy12345.dat", 1500000) = 0 Then MsgBox "Could not create the test file.", vbCritical, AppName End If If WHX_OpenEx("C:\Dummy12345.dat", 2) = 0 Then MsgBox "Could not open the test file.", vbCritical, AppName End If Call WHX_Goto(VB2API(1024)) If WHX_Write(Buffer(0), 512) = 0 Then MsgBox "Could not write to the test file.", vbCritical, AppName End If Call WHX_Save Call WHX_Close End Sub | ||

OK, I will have to check this. | ||

I have to confirm that the second parameter in WHX_OpenEx was ignored, so the edit mode depended on what mode was generally selected for newly opened files in WinHex. Will be fixed with WinHex 12.7 SR-3. |
