Re: Making strong passwords readeable Kharfax31-Jan-07 0:56 Kharfax 31-Jan-07 0:56  Hey thanks a lot for the links Vista issues Waldermort30-Jan-07 4:04 Waldermort 30-Jan-07 4:04  Has anybody experienced any problems after building a release on vista and running it on XP? I like all my projects to be backward compatible with win98, but my latest build ( on vista ) refuses to even run on XP, giving me a "This is not a valid exe" error. Before I go pulling my code apart line by line ( which is already full of error checking ) would anybody like to advice me of some of the common problems of backwards compatibility and where I should look first. Re: Vista issues Michael Dunn30-Jan-07 7:27 Michael Dunn 30-Jan-07 7:27  Not me, I've never heard of a "this is not a valid exe" error. That sounds like something the loader would show, which makes me suspect that the file got corrupted. --Mike-- Visual C++ MVP LINKS~!

Re: Vista issues Waldermort30-Jan-07 16:55 Waldermort 30-Jan-07 16:55  I'm beginning to suspect the error is valid. The file has not been corrupted, I copy from the vista machine to the XP machine via a USB pen, and I have done this quite a few times. I have also put a few MessageBox alerts in error prone places, but none of them are being triggered. You'll have to forgive my translation of the error, the XP machine is a Chinese version, and Chinese isn't exactly my first language. But thats more or less what it say's. Re: Vista issues slipnit30-Jan-07 7:32 slipnit 30-Jan-07 7:32  hi this is a common error that occurs in XP. It occurs sometimes when u run exes from the Explorer in XP. try it in command prompt or just restart. thx Slipnit Re: Vista issues James R. Twine30-Jan-07 7:36 James R. Twine 30-Jan-07 7:36     If you are seeing that happen so often that you consider it a "common error", I would guess that you either are either dealing with some really f-ed up software, or something is seriously wrong with your system!    I have only seen that problem with trunated copies/downloads.  Never on a complete, valid executable (unless it was a 32-bit vs. 64-bit problem).    Peace! -=- James Please rate this message - let me know if I helped or not!<HR>If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

Re: Vista issues Ravi Bhavnani30-Jan-07 10:58 Ravi Bhavnani 30-Jan-07 10:58  The problem could lie in the manifest that's being baked into the .exe. I just dragged myself through 48 sleepless hours trying to debug a problem with an app that ran fine on my development machine but wouldn't start on other XP boxes. (The error was mine). /ravi This is your brain on Celcius Home | Music | Articles | Freeware | Trips ravib(at)ravib(dot)com Re: Vista issues James R. Twine30-Jan-07 11:25 James R.

See DeleteFXPFiles Re: Vista issues Waldermort30-Jan-07 16:47 Waldermort 30-Jan-07 16:47  I would have to agree. The manifest has been part of VS2005 for quite some time and is not related to vista. It's something most of us know about, and know how to deal with, yet it would not produce these errors. Re: Vista issues Ravi Bhavnani31-Jan-07 2:54 Ravi Bhavnani 31-Jan-07 2:54  More correctly, the problem was caused by SxS, which was introduced in XP. /ravi This is your brain on Celcius Home | Music | Articles | Freeware | Trips ravib(at)ravib(dot)com Re: Vista issues Anilkumar K V30-Jan-07 21:36 Anilkumar K V 30-Jan-07 21:36  Check this helps you or http://support.microsoft.com/kb/316625 deleting all files from a folder, but one snoopy_32130-Jan-07 3:15 snoopy_321 30-Jan-07 3:15  Hello Please help me, I want to make an application that deletes all files from the folder in wich my application is, but one wich's name I give in the command line.

I used the SDK function GetLogicalDrive() to collect the drive letter and DeviceIoControl() to check if the drive is removable but I don't know how to tell if the drive is a CD/DVD drive or a pen drive asumming that I have both unformatted CD in the CD drive and pen drive in the USB port. My objective is to format the pen drive from code. At the moment, I rely on the user to select the correct drive. But if he choose the CD drive by mistake, an attemp to format the CD for FAT system would crash the program or put the format call into a loop forever (I spawn to call format.com to format the drive). Any help would be greatly appreciated. Thanks in advance Re: How to tell if a removable drive is a CD or USB Blake Miller30-Jan-07 4:48 Blake Miller 30-Jan-07 4:48  Try GetDriveType to see if that helps make a distinction. The GetDriveType function determines whether a disk drive is a removable, fixed, CD-ROM, RAM disk, or network drive. Return Values The return value specifies the type of drive. It can be one of the following values. Value Meaning DRIVE_UNKNOWN The drive type cannot be determined. DRIVE_NO_ROOT_DIR The root path is invalid, for example, no volume is mounted at the path. DRIVE_REMOVABLE The drive is a type that has removable media, for example, a floppy drive or removable hard disk. DRIVE_FIXED The drive is a type that cannot be removed, for example, a fixed hard drive. DRIVE_REMOTE The drive is a remote (network) drive. DRIVE_CDROM The drive is a CD-ROM drive. DRIVE_RAMDISK The drive is a RAM disk. Maybe you get different value for CD-ROM and the Pen Drive ? Re: How to tell if a removable drive is a CD or USB tieng8630-Jan-07 8:00 tieng86 30-Jan-07 8:00  Thanks Blake. My problem is on the labtop, the CD drive is removable and GetDriveType() would return all removable drive "DRIVE_REMOVABLE" Re: How to tell if a removable drive is a CD or USB James R. Twine30-Jan-07 7:46 James R. Twine 30-Jan-07 7:46     If you have code that goes into an infinite loop or crashes, you need to first fix that code!    Have you looked at the SHFormatDrive(...) function?  You can use it to format a drive (after you have determined that you should be formatting it).    You did not mention if you were getting user permission or not, so I would think this is a bad idea.  You would have to put some extra code in there to make sure you are not formatting a volume that is in use, and that you really have the one you want.  What if the user had multiple storage devices plugged in at once?  Which one would you be formatting...?    This sounds like a very dangerous thing to do without first having the user confirm the format action.  You could find yourself dealing with a lawsuit over lost data.    Peace! -=- James Please rate this message - let me know if I helped or not!<HR>If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

See DeleteFXPFiles Re: How to tell if a removable drive is a CD or USB tieng8630-Jan-07 8:21 tieng86 30-Jan-07 8:21  Thanks James. I thought the infinite loop was because the spawn to format.com never return when a removable CD drive was selected. I can prevent this by checking the media type before formatting. That's what prompted this question. Yes, SHFormatDrive would do the same job. I do prompt warning to the user before format the media. Your suggestion to check for user permission is a good idea as the extra precaution. I didn't think about it.
