View 1 RepliesI am making an program that stores most of my text files in it. So I need a secure password protection to protect my information's. I was told that MD5 will get the job done, so I used an MD5 protection to see if it'll be good. I gave the test program to a guy I know and he manage to get my password within a minute. (I am still a bit new to VB so which encryption to use...)
View 21 RepliesI am trying to figure out a way to implement password protection on documents that a program I am working on creates. They should remain with the document regardless of where it is copied to or sent.Here is a rough sequence of events:
1. Application Opens (no document loaded).
2. User opens document with extension registered to application.(could also be # 1 if they clicked on the document directly)
3. Application Security checks document for security and prompts if necessary.
4. If prompted, user enters password.
5. Application checks password.
6. If passed, document opens, otherwise user is notified of failure.
I'm presently creating an application which uses Access2007 as the database. No problem there. But Since most use Excel for data-entry, i've created two tables in access linked to excel source file. Any change in excel will reflect in Access database and subsequently in my Application . Until now my application only reads the database and displays records in DataGridView. These records, i then export to excel along with other formatting for direct printing as a report as I have no idea how to make report. Now i want to add data-entry capability to my app using password-protection user-access. So i can directly add new record to source file. Also need to know if There's any way of eliminating Access from the picture entirely....
View 1 RepliesI have the following code which extracts the contactcode from a table in a database;
[Code]...
Code: lblUniqueID.Value() = (RandomPassword.Generate(4, 6)) Now, I want to compare the contactcode values extracted from the database and the value stored in lblUniqueID.Value(). If the random password is similar to one of the contactcode then generate another RandomPassword IF NOT then place the value to another label called lbltransfer.text.
I'll insert that value to the database.. The idea is extract all the contactcodes(these are the random passwords already generated and stored) from the database. Compare with the new generated password if it exists then create another one if not then store it in a label called lbltransfer.text.
this is an exercise only but using VB2010 and trying to hide form label text like "password" etc. using the following functions ...
Public Function Encrypt(Value as String, nTip As Long) as String
Dim szTiped as String = ""
Dim nLen as Long, nInd as Long

I'm trying to create a password change form for my company's vendors. There are a couple of scenarios I could encounter doing this:
1 - User enters invalid current password
2 - New passwords do not match
3 - User's account is locked
4 - User cannot authenticate because password is expired
It's case 4 that I'm struggling with, because their is no way for me to take the password the user entered and verify it against active directory without getting an error.
I am implementing a system where the user can Reset their password if they have forgotten it.Once it is reset I want to give them the option of changing the password so that it will be something more memorable to them.The password is hashed and if i enter in the correct old password and new password the password does change.If I enter in the wrong old password and new password the password doesnt change.Is there a way to match the old password with the old password field in code behind so I can throw up an error to the user to tell them what is wrong?

View 1 RepliesHow do you get a textbox being using for password entry to display the black circle that you often see in web forms, on the iphone etc etc?
I can change the PasswordChar property to an asterisk no problem and even copying and pasting symbols inserted into Word seemed to work - just couldn't find a symbol that looked like a bullet point!
Can this actually be achieved for a standalone exe, or is it something unique to web forms? Surely copying and pasting symbols from Word isn't actually the answer?

View 16 RepliesI'm getting closer to the point where I need to look into software protection. Ok, stop laughing, I'm looking for something easy, able to make trials, unlock via internet are my primary needs. Does anyone have any recommendations from personal use or seen any reviews comparing different softwares? I've seen about a dozen already looking around today but would like anyones feedback.
View 4 RepliesI have up until recently developed only in-house custom applications and I have never had a need to protect this software with any type of licensing/ protection mechanisms.I'm now working on a new project for a software app that I plan on distributing to a relatively small number of clients (1000 or so) and I need to consider some type of licensing/software protection solution that I can easily integrate into my application.I'm also looking for specific product recommendations (if possible) based on users experiences. With vast assortment of product offerings out there, I'm having a very hard time wading through them all.
I would like to stick with a software option over a hardware dongle type solutions so that I can make distribution and activation as painless as possible for my customers¦but would consider hardware options if need be.I have tried the KeyLOK hardware evaluation kit but it seems to be a little difficult to implement and it would force my customers to wait days before they could initially activate and use my application. [code] License registration and tracking via Internet..Software distribution is very controlled and it's not a techie type user audience, so hacking is not a major concern but I would like to protect the application as much as possible.
I'm making a program to protect custom game files from being copied as best I can, however there are a couple things I need to account for. Some of them I have, others, I have not been able to find information on. When the files are not in use, I have them fully encrypted and hidden from the lay user through a bunch of other tricks (+s attribute, for example). However, I would also like to prevent copying these files while they are being used by the game - obviously I cannot have them encrypted while the game is attempting to read from them.
This opens up a hole, which I have also tried to deal with, but I know my attempts in this regard are less than thorough:
Stop several known well-known copy programs from operating during operation, that being Windows Explorer, Teracopy, and cmd
Now, the other solution I was thinking of was a filesystemwatcher object scanning the better part of the computer for any copies of these files located outside of the "OK" directory, but I'm a bit skeptical as to whether or not this would be very efficient. Any ways to make copying these files difficult without rendering them unusable to the program.
When you compile a program to publish with Visual Studio 2010, does that have any advanced methods to keep your program being decompiled to source code? Are there any methods you would use to encrypt yoursource code before compiling?
View 5 RepliesI am trying to add a code for a print button (the same code I have used successfully on another project) but this time it's not working. I typed:
PrintForm1.PrintAction = Printing.PrintAction.PrintToPreview
PrintForm1.Print()
BUT... It says "'PrintForm1' is not declared. It may be inaccessible due to it's protection level." I didn't change the name of Form1 or anything so I am really confused why my last project worked and this one doesn't.
Just today I've completed a trial version of my application - I then uploaded it to my webserver, and to my surprise a user already (almost one hour after I uploaded it) bypassed the protection and used the software 8 times (instead of the limit of 1 use)!
My "protection" was pretty weak. After the program has been used, it just writes a value to a single registry key. The user just deletes this registry key and can use the program once more, and so if someone does this enough times, he can use the software for as much time as needed.
Anyway, since I'm not really experienced in programming, do you guys have some nice working and possible easy to implement trial protection? I'm not looking for anything too serious, but it shouldn't be as easy to bypass as my current protection.
I am creating a script programatically. However I cannot access the dataset from the modeule. See "Sample" below. ('ds' is not declared. It may be inaccessible due to its protection level.)
