hello everybody, my app encounters some troubles when used with Vista. Under win2K or XP no troubles, every thing works great, but under Vista fprintf doesn t do anything ... The problem is that with fprintf I can't write anything inside of my file. I precise the writing are KEYWORDS for my app, that can be also edited with a notepad if needed ( users under Vista are obliged actually to do it to run properly the app). Here is the code, may someone have a precise idea about the problem with fprintf ? Thanks! 1#include "allegro.h"
2#include "stdio.h"
3#include "winalleg.h"
4#include "MMSYSTEM.H"

You should add checks to see if fprintf is returning a negative value or not. I think what's happening is that the files you're creating on the Vista system you're testing on are being given read access by default, but not write access, but that's just a guess. It would be helpful to know the return results. --- Kris Asick (Gemini) --- Kris Asick (Gemini) |

you mean if(fp=fopen("my_dmx_interface.txt","wr")) should be "wb" ? I have no vista near me but I will change the type of opening, you may seriously be right in your analyse .... "step by step" |

I don't think "wr" is really valid anywhere by strict interpretation of the standards. Read and write should be "r+". |

Doesnt windows need r+b or something strange like that? |

well it is working fine under 98SE, 2K and XP. But Vista NO... "step by step" |

You do need to run your program under Administrative privileges if you want to write to Program Files in Vista. |

Thats what I'm thinking, can you try putting your program into my documents and running it there? In vista you should be always writing to the users document folder (they had a session here recently) rather then the installation location. _________________________________________________ |
