In my app i have to copy and then delete image files from memory cards, the problem comes when some of the card inadvertantly have the "Lock" switch engaged turning them to read only.
When trying to delete these files i want to log the failure to delete but not show any UI messages until a time of my choosing.
Here is some sample code i am having trouble with.
Sub Main()
Try
System.IO.File.Delete("K:BYZTCSQ_0050.JPG")

This works fine when debuging i.e. it tries to delete the file and if not the error is caught and i can proccess it as nessecary, but when i build and run the app i get an error message telling me that the file cannot be deleted.
To test this code you will need a drive that can be physically set to read only (USB memory key, SD card) and try to delete a file on it while debuging and after a build.
Why would the same code run differently and how can i stop the excess error messages?

I have tried running the program as administrator, using a different registry value, turning off all of my antivirus & firewalls and loads of other stuff. The strange thing is that I can delete the registry key in regedit, or any other program, it's just my program won't do it. It works on another program with exactly the same code (same startup code, different program).

I created a time clock program for a friends business and I added a place for them to use pictures for the employee. It uses the employee number to grab the photos from a folder and displays it (ex. employee #1 would like for 1.jpg). I want to let them change the picture without going to that folder, delete the old one, copy the new one and then rename it. I also let it have a default photo (theres 2, one for females and one for males, which are matched by there gender) just in case they haven't had a photo added yet. My trouble is, if I try to update the photo and delete the old photo, I get an error saying its in use by another process. My code goes like this, check to see if the employee has a photo, if it does, it will delete that photo (this is where I get the error), copy the new photo (already selected in previous code) and then sets the photo. how to release the photo from the project before I delete?

I'm building out a decommissioning application that will allow an individual to provide an computer name and the utility will go out and purge the computer record from various locations. I'm running into a problem when attempting to delete a computer account from Active Directory. I'm impersonating a service account that only has rights to "Delete All Child Objects" within a particular OU structure. The code below works if I run it with my domain admin account; however fails with an "Access Denied" when I run it with the impersonated service account. I have verified that the permissions are correct within AD as I can launch Active Directory Users and Computers using a "runas" and providing the service account credentials and I can delete computer objects perfectly fine.
Wondering if anyone has run into this before or has a different way to code this while still utilizing my current OU permissions. My gut tells me the "DeleteTree" method is doing more then just deleting the object.
