.... I found the solution in another newsgroup. Great - sorry I didn't have time to research it sufficiently here. Sharing what you found would be nice, though: I'm curious how to do what you wanted to do, because it seemed to me to be an original deficiency in the Win32 interface and if SetEndOfFile doesn't remedy that I'd like to know what does (other than going down to the native API). - bill |

Maybe you should consider just shutting up. That's what a wise man suggested to me. |

I ask questions just in case someone already knows the answer. If they have to figure it out, they'd be doing my job. Sharing what you found would be nice, though: I'm curious how to do what you wanted to do, because it seemed to me to be an original deficiency in the Win32 interface and if SetEndOfFile doesn't remedy that I'd like to know what does (other than going down to the native API). - bill After playing with it for a while, I've decided that SetEndOfFile does exactly what you'd want it to do in a NORMAL situation. Problem is that my situation isn't anywhere near NORMAL. Normal stuff is boring ;-) mike -- Return address is VALID! |

Not at all: just explaining why my earlier message only *turned out* to be useless, rather than was so in principle (hence was worth posting on the off-chance that you were capable of benefiting from it).

API exists to SetEndOfFile, it is documented. Indeed, and that's clearly the right approach since it seems to accomplish what's desired using a documented interface. But it was not what I was remembering (see my other reply). - bill I have two problems writing code. I'm lazy. And I have no idea what I'm doing. I found a VB6 code example and hacked it as follows: Private Sub Command1_Click() Path = "x:\big1.txt" hFile = CreateFile(Path, GENERIC_WRITE, FILE_SHARE_READ Or FILE_SHARE_WRITE, ByVal 0&, OPEN_ALWAYS, 0, 0) If hFile = -1 Then End WriteFile hFile, ByVal "Very-very cool & long string", 28, BytesWritten, ByVal 0& SetFilePointer hFile, 900000000, 0, FILE_BEGIN SetEndOfFile hFile CloseHandle hFile ... This does make a big file, but it fills the file with zeros and takes 18 minutes to do it. Am I using the wrong arguments? I need to do this 16 times...I need to get rid of the 18 minutes X 16... You probably want to use SetFileValidData(). You'll need to authorize yourself properly first (you need to set the SE_MANAGE_VOLUME_NAME privilege for the processes' access token with AdjustTokenPrivileges() - and you'll need to be an administrator to do that). |
