VS 2005 How To Choose Random File
Aug 20, 2009I need my code to be able to choose 5 random files from a folder. I was hoping I could instantiate the Scripting.FileSystemObject then grab the target folder as an object and do something like FolderObject.Files(12).Name but apparently that's not doable. What I did works, but is sloooow:
FS = CreateObject("Scripting.FileSystemObject")
Folder = FS.GetFolder("c: emp")
for y=1 to 5

VS 2010 Randomizing - Program Randomly Choose Questions - NEVER Choose Same Question In Same Program
Dec 20, 2011I am currently working on a family project which is based on "Who Wants To Be A Millionaire?" show. There is a huge diffrence between the show and my project. My project is a christmas edition and the goal is not to get money or something, since I will not add it... Erhmm... Let me get to the point. I have already designed a layout and scripted some things. I have about thirty questions but I do not want them to always spawn in the same array, if you know what I mean. I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D. I have got everything, I just need a code.

View 10 RepliesDisplay Previous Shadow Copy Versions Of File Allowing User To Choose One?
Dec 11, 2011I'm writing an Excel file recovery program with VB.Net that tries to be a convenient place to gather and access Microsoft's recommended methods. If your interested in my probably kludgy, error filled, and lacking enough cleanup code it's here: http:[url]..... The basic functionality seems to work although I haven't tested graph macro table recovery yet.
It occurred to me that Vista and Windows 7 users could benefit from being offered a list of previous versions of the file within my application if the Shadow Copy Service is on and there are previous copies. How do I do this?I looked at a lot of web pages but found no easy to crib code. One possibility I guess would be to use vssadmin via the shell but that is pretty cumbersome. I just want to display a dialogue box like the Previous Versions property sheet and allow users to pick one of the previous versions. I guess I could just display the previous version property sheet via the shell by programmatically invoking the context menu and the "Restore previous versions choice", however I also want to be able to offer the list for Vista Home Basic and Premium Users who don't have access to that tab even though apparently the previous versions still exist. Additionally if it possible I would like to offer XP users the same functionality although I'm pretty sure with XP only the System files are in the shadow copies.
I looked at MSDN on the Shadow Copy Service and went through all the pages, I also looked at AlphaVSS and AlphaFS and all the comments. I'm kind of guessing that I need to use AlphaVss and AlphFS and do the following?Find out the list of snapshots/restore points that exist on the computer.Mount those snapshots.Navigate in the mounted volumes to the Excel file the user wants to recover and make a list of those paths.With the list of paths handy, compare with some kind of diff program, the shadow copies of the files with the original.Pull out the youngest or oldest version (I don't think it matters) of those shadow copies that differ from the recovery target.List those versions of the files that are found to be different.This seems cumbersome and slow, but maybe is the fastest way to do things. I just need some confirmation that is the way to go now.
File I/O And Registry :: Random Access File Larger Than Text File?

Oct 19, 2011Years ago when coding with VB6 and earlier, I used a file open command to create, read, and write a file that made it easy to store useful information.I believe it was binary and you wrote/read the data to a specific line in the file. When you opened the file with something like notepad, it just showed random ascii chars. When I needed a line of data, I could specify what line to load it from.

Feb 28, 2012I have managed to learn a little of VB 2008 but I'm still struggling. I managed to convert one VB6 program to VB .net but all the file IO in it is sequential access.I'm trying to convert a VB6 program to .net. This program uses almost entirely random file IO.In one of the books I have, I found an example which, with a minor mod worked. I tried using that code to modify my program and it does not work. In my code, the FileGet results in the obj containing null strings. Yet in the sample program using the same structure, the obj contains actual data.The file is being opened because the record count is calculated correctly [iUpper = LOF(F_Trk) / TrkLen].
I used a Type in VB6 which I converted to a Structure in VB 2008. The function in which the problem occurs is below as well as the Structure declaration and the Function it calls (PAB) which is a derivation of the PathAddBackslash API call.Is there an easier, more efficient way to achieve the same results in VB .NET?[code].....[code]......

Create A XML File With A Random Name?
Jun 11, 2009I have some really sloppy code that creates an XML file with a random name. The random name (SessionID) is passed into the Sub, but the sub checks IF File.Exists first. If it does exist, it creates a new randoms file name based on System.Random (has to be done this way because it is also a SessionID).

Jan 19, 2010Im creating a login system that allows staff to clock in using a 5 digit code. Staff members can also use the "add an employee" function to add a new employee to the Random File.The problem is, everytime i try to create a new employee and hit the save button, the new record writes over the existing records, one by one, everytime the programme is stopped and started up again.
My Question is: How can i get the new record to be saved, without deleting existing records,
Here is the save buttons click method:FileOpen(fileNumber, "C:employee.dat", OpenMode.Random, OpenAccess.Write) 'open the file with Write Access
myEmployee.name = txtNewName.Text 'adds the name
myEmployee.id = txtNewID.Text 'adds the ID
FilePut(fileNumber, myEmployee, n) 'save to the file
FileClose(fileNumber)
Creating A New Random Generator Each Time Should Reduce The Number Of Random Repetitions?
May 26, 2011I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......

IO.File.Delete Random UnauthorizedAccessException [.NET]
Nov 27, 2010I'm using My.Computer.Filesystem.WriteAllBytes to write out an executable stored in my application's resources to it's startup directory. After running the executable, I then delete it. Everything works fine; however, I'll randomly get an UnauthorizedAccessException for no reason. After getting the exception, I can manually delete the file with no problem. Here's the full code:
' Convert MP3
' First, copy out converter

What perplexes me is that I literally just wrote out the executable, and nothing else could possibly be using it. I've checked the file attributes and it's not read-only. My application is also running as an administrator.
