View 8 Repliesis it possible to have my app protect a folder's files from being viewed by other users. like, if i set the command to protect a folder, then if anyone tries to access that folder will be prompted with a msgbox.
it probably means having a separate app loading at windows startup and constatly running in the background to make sure that folder isn't being accessed.
so much work to do and so many choices to choose from...

View 1 RepliesI'm interested in password protecting my external hard-drive. i know there is already programs that can do this but i want to make my own.
make a program that would at start-up pop up and make the user put the password if not then the partition will be set to hidden. also would be a good idea to set the partition hidden until user puts password.
lately, ive had a lot of free time and have been trying to password protect my flash drive in VB 2008. and ive figured out almost everything i want with it, but ive come to a bit of a roadblock. as of right now, ive got 2 accounts, but thats all ive done so far, because every account has like 3 if statements, and it would start to accumulate a bit of i made anymore. so, ive been looking into using a database, and having it retrieve the password and username from there. ive searched for hours, and have found a lot of little bits and pieces of code, but nothing that would work for my situation. Will somebody tell me how i would:
1: make sure that the password and username match in the database when i click the confirm button
2: add a new username and password to a database when they want to make their own account
3: save changes to the database when i log out and move to another computer
also, is there a simple way to log the date, time, IP address, and Username, put it in a text file, and email it to me? i would also like to know how to open a flash drive using its name, and not its letter, cause its a different drive letter on different computers.
I've created a library class in vb.net that obtains some data from a database. This dll can be used by other apps so I want to protect the access to this dll's methods by using a login and password. How can I implement this?
View 2 RepliesOK, so, I made a program that locks the computer with a password, to help you protect data from other people. It's quite simple, you open the program, it shows up in full screen, "To access this computer please type in the password"....etc.
BUT, I want it to have a "Guard". To make it act like a screen saver does. That's my plan: So, you typed in the password, and close the program. And then, if you didn't move your mouse, or press a key, or you're not watching a movie, for more than 6 minutes, I want it to automatically launch the program. Until now, I've just put in Form2.Show in the Form1's (which is the password-protect program) FormClosing class. I also made the Form2 on Full Screen, and it's opacity to 0%. That's where you will move your mouse. I made all the code until now, but I need code for making it act like a screen saver.
Recently I've started experimenting with Visual Basic 2008, and just out of curiosity am trying to password protect my flash drives. (At the school I go to, it takes a couple seconds for things to disappear). So, I've got it to the point where I can have multiple "accounts" with their own passwords, ive got a lost password button, and a bunch of other stuff. But, anybody can just click out of it and go into the folder themselves, so I've been looking for a way to lock the focus on my password box. I've looked for hours and have found a lot of things that keep the focus on like a second form, so you cant go back to the first one, but I was still able to launch applications and things because the desktop was still active. I still haven't found one that keeps the focus locked on the first form and nothing else.

View 4 RepliesI've a winforms application that is using SQLite database. There is no encryption on the database (data has to be shared with other user). It is a stand alone application with a stand alone local database.
The difficulty I'm encountering is when people go to bring all the data together.The databases are attached, data imported, but records are differentiated by a database GUID.At any rate I am desiring to have a database selection screen that is protected by a password to prevent users mistakenly switching databases (and some level of protection against malicious use).
Thinking it's probably not a particularly good idea to store the password in an unecrypted database.Security is not a large issue as this is only distributed to users that need the software.
What would be the best method to have the user type a password when they attempt to access the database selection screen? ShowDialog? Pop open a new child form with a password TextBox, then on validation (via button?) close the password form and open the protected form?I see a fair bit about protecting a whole application, but not so much about a specific form.

But I have no clue how to implement it into my code.In this gz file there are only around 50 lines but there are files with over 1000 lines. So I tested & indeed this seems to be the problem, because if I increase the buffer(4096) more lines are extracted.

I'm currently generating some excel files using vb.net (2008). I want to protect the workbook or sheet inside, so that the user cannot edit anything within the file.I tried some options from MSDN but no luck and some other forums but no luck.The following is my last few lines of code in the program.
Code:
ExcelReport = New Excel.ApplicationClass
ExcelReport.Workbooks(1).SaveAs(ExcelFileName)
I basically don't want the user to edit anything inside the file. Perhaps a printout is allowed.
I am compressing a dataset converted to XML using the GZipStream class added in 2.0. There are a few things bothering me about this. Here's the code I am using to decompress the XML file:
Using inFile As New System.IO.FileStream(flnm, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
Dim zStrm As New System.IO.Compression.GZipStream(inFile, IO.Compression.CompressionMode.Decompress)
Dim buff(999) As Byte
[CODE]...
This seems inordinately awkward, as I am taking the stream, reading it out into byte buffers, then writing those byte buffers to a memory stream that is then passed to the dataset.ReadXml() method. The reason for this seems to have to do with what is happening in the line colored red. That line is adding a closing > onto the end of the stream. Without that, ReadXml complains about an unclosed dataset. I found out that the > was missing by writing the stream into a string and pasting the string into WordPad. Without that missing >, it appears that I wouldn't need to be using that memory stream at all, and could simply pass in the GZipStream to ReadXML, but as far as I can tell, it's impossible to look at the GZipStream to be sure that the > is not there, and it may be impossible to add it (I haven't tried).
So why is the > missing? Here's the code used to create the file that is being read into the filestream in the above
VB Using ms As New System.IO.FileStream(flnm, IO.FileMode.OpenOrCreate, IO.FileAccess.Write, IO.FileShare.Write)
Dim zStrm As New System.IO.Compression.GZipStream(ms, IO.Compression.CompressionMode.Compress)
ds.WriteXml(zStrm, XmlWriteMode.WriteSchema)
End Using
The real kicker to all of this is that while I was dissecting the first chunk of code, I added a line to check for cnt<1000. My intention was to see the last buffer that was being written into the memory stream to see whether the final > was actually there, or not. To my surprise, I reached the cnt<1000 twice. That means that one read did not read a full 1000 bytes, but read only 675. The next three or four reads were a full 1000 bytes, then the final read was just a few hundred bytes. It is my understanding that Read will return a full buffer if there are that many bytes left to read, and there were, so why did it return only a partial buffer? That suggests that there might be a hole in my XML, though with a half meg file, it's a bit much to read through it looking for something missing. However, the XML that was returned was turned into a dataset that I then merged into some existing data using code that has been working with uncompressed XML files, and I got an error that I should never have received. That may indicate that the XML was, in fact, missing something, though I will have to study the matter further to figure out whether or not that is the case. My major question has to do with the missing '>' at the very end of the file.
