I use this code to create dump files of my database. Now what I want, if possible, is to encrypt it so that when it is viewed in notepad or anything similar, average users cannot read it.
Call isDirectoryExist()
Call createDbBackupName()
Dim myProcess As Process = New Process
Dim strUser As String = "superadmin"
[Code] .....
Of course, if it encrypted, it has to be decrypted before querying the dump file. I have no idea what encryption I can do in vb.net and mysql
I modified my first code
Process.Start("C:/MySQL/bin/mysqldump.exe", " --host=localhost --user='" & strUser & "' --password=1234 """ & strDbName & """ -r """ & strPath & newDBName & """, --cipher /e /a '" & newDBName & "' ")
But the output file contains nothing whatsoever.
I have this code which saves the dump file in a static path or destination Process.Start("C:xamppmysql inmysqldump.exe", "-u root ipoint -r C:Backupipoint.sql") MsgBox("Backup Database Created")
I want to choose the path by using the folder browser dialog which will put the path on a textbox but this code below doesn't work Dim path2 As String = tb_path.Text Process.Start("C:xamppmysqlinmysqldump.exe", "-u root ipoint -r '" & path2 & "'ipoint.sql") MsgBox("Backup Database Created")

I found this video tutorial on youtube. Unfortunately I can't seem to find source. How to do what he is doing. Also how to encrypt the password at the registration process. Then encrypt it while logging in. Video - [URL] My login code - [URL]
I am working on a application that stores videos, images and files. I would like to give the user the possibility to encrypt them. I am tying to use AES to encrypt them but the problem is that the decryption takes to long.I was hoping that the loading time from the hard disk of the encrypted file was far longer than the process of decryption of an image for example but i was wrong
So if i try to 1) load the image 2)decrypt it and 3)load it in a image control it takes 15 times more time that loading the original file not encrypted
So I can encrypt small files using Des Encryption, but whenever I try encrypting large files, The program's memory usage skyrockets! Would anybody be able to get me some code that will let me encrypt large files (It doesn't have to be Des, but I need to be able to support any length password).
How to grab information from a mysql database and output it to a text box i.e., I have recently inserted name john and then I have a text box that I want the name john to appear in how do I do it? I can successfully connect and insert, update, and delete but cannot select?
I'm in the process of switching my application from MSSQL to MYSQL. When I was using MSSQL, I retrieved the last auto increment value via
Private Sub dsImpoundInformation_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles dsImpoundInformation.Inserted _impoundId = e.Command.Parameters("impoundId").Value End Sub
[Code]...
ultimately, I'm just trying to get the last auto increment value but there are other sections of my code in other applications that I plan on switching to MYSQL that depend on output parameters. I have't yet explored using stored procedures but at this time I would like to get this to work in a similar fashion to how I had it with MSSQL.
i'm working on an e-voting system for my thesis... but i'm having problem on how to output the data in all the rows in the database in a check box. so it means that the number of checkbox is equals to the row of the table. i manage to output only one data from the first row but i don't know how can i output all the succeeding rows.
this is my code so far Private Sub LoadCandidates() SqlString = "SELECT * FROM candidate" 'Function for searching by candidate ID number
i am trying to make a small program to encrypt files using AES, and then have the password from the AES encrypted using RSA for its use of public keys. i've got the AES part working fine and i found a good RSA tutorial here url....but after i encrypt the AES password (which is saved in a .txt file) using RSA, then i try to decrypt it again, it comes out as an empty .txt file!
I'm designing a program to encrypt and decrypt files using TripleDes Encryption algorithms but am having issues decrypting an image file. The file encrypts in the correct manner, but when I go to decrypt the file and open as an image I get an error message. One example is when trying to open the file in paint a message appears stating 'c:New FolderDecrypted.jpg Paint cannot read this file. This is not a valid bitmap file, or its format is not currently supported. My coding for the form is shown below:
Lets get down to it, Basically, I'm making a kind of "Anti-Hack" for a project I'm working on.The basis of the "Anti-Hack" is the check processes for names of known Memory Editors, For example, one memory editor I am scanning for is Cheat Engine.exe, I am using this code to scan for it, then I use the result to activate a different piece of code.
If Process.GetProcessesByName("Cheat Engine").Length = 0 The 'It's OK Else <Removed for obvious reasons> End If
Basically, I don't want my code to look like a library of If statements when the only thing I am changing is the process name, what I want to do, is have an encrypted .dat file with an array or list of known tools. I want to then go through the array/list and keep checking for instances of them running.I know nothing of how to encrypt/decrypt .dat files through VB. (I'm not an expert at it atm )I am open to other ways (Easier ways) of doing this, like a Class with a list of names etc.
**NOTE** I would rather it be a separate file as the program features an Auto-Update feature, so it will be easier to update the list.
**IMPORTANT**Also, I would like to know how to hide my process, so it cant simply be ended, It may sound suspicious but people will be able to just close it and start hacking T_T, Unless there is another way, I would appreciate it (Like making it so it cant be ended etc.)**IMPORTANT.
I'm attempting to create a little library to encrypt and decrypt Files with AES. There are loads of examples of how to do this on the internet so coding is not a problem. There are however a few questions regarding cryptography and AES in general.
#1 Does the IV need to be kept a secret like the key ? #2 Can I just hash a string with SHA512 to make a key for AES ? or do I need to use PasswordDeriveBytes ? #3 In the case of me using PasswordDeriveBytes Do I need to keep the salt a secret ?(or do I need to keep it at all) #4 Can I generate the IV from the same password that the Key is derived from ?(if so How ?)
i have 2 problems the first problem is if i have a .txt file how can i extract specific data. the second problem can i create batch files on the fly because of the need for a variable again it may not make sense but shout tyrannically
There is way to input comma delimited files: Using MyReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(currentfile) MyReader.TextFieldType = FileIO.FieldType.Delimited MyReader.SetDelimiters(",")
Is there an equivalent way to output a comma delimited file. The approach I used in earlier versions of Visual Basic does not work in .NET.
I have been using: Printline(1, val1, val2, val3) In .NET that is not comma delimiting For now I am hardcoding ... & ", " & ... between variables.
I'm new to Visual Basic so im wondering if there could be made a program when it opens it connects to directory of my website and ouput the files, so you can see them, delete, download etc.
I have some XML files that are needed with my application, they are included in the project, I have the properties set to:Build Action: ContentCopy to Output: Copy if NewerWhen I publish, they get included with all the other setup files, but when it actually installs they are not getting copied to the output folder. (I also tried Copy Always and that didnt change it)
Need to design a program that can encrypt and decrypt messages stored in simple text files using a private key stored in a separate file. Software should also be able to allow the users to enter simple messages that either displays the encrypted or decrypted message. The encryption method should use a simple substitution method. It should be set out in the following format:
Example (the "@" is the separator):
@ The character The Code End of line A @ 4gh EOL B @ 84!9 EOL
Has to use the 256 ASCII character codes. The separator will be used to separate the character and its corresponding code.Here are the pseudocodes I have come up with:
� Read any private key file separator = readline(file); while not EOF(file) do tempStr = readline(file);
I have finally finished an application which works really well on the PC upon which I developped it using VB 2008 Express.My problem is that when I publish it and try to install the ClickOnce output files on another PC (tried two so far, both WinXP) I get a missing files error. There is an error output saying that downloading the .exe.manifest file did not succeed. Unfortunately the error detail is confusing and does not seem to indicate exactly which files are missing.On both of the PC's that I tried I was prompted io install .net 3.5 SP1, which seemed to have been successful. The inference is that it is not a .net file that is missing.
I have a video encoder app made with VB6 that users frequently have issues with. The problem that people encounter is that files do not show up in the output folder where my application is set to write them. The output folder is located in C:Program FilesMyAppOutput. Vista users can sometimes click "Compatibility Files" and see the outputted files. Sometimes I must tell users to "Run As Administrator.."
so here is my scenario. I have two input files... both are plain text files. File1 has customer name, customer address and invoice number. File2 has customer name, customer address, invoice number AND a keyline. File1 will only contain some of the records in File2, and it will change daily. I need to be able to compare File1 against File2 and output one file (preferably an Excel spreadsheet) with the info from File1 and the keyline from File2, that matches the duplicated info. I know the basics to get it to work, but I'm not sure what would be the easiest way of doing this... File2 can have up to 100,000 records per day. I'd only need to run it once a day though.
I am developing a software and i need to make it save a text document, I can make it save it by writing the path of my document on my machine but it wont work on other machines when installed, how can I make it do this?
This current project involves dumping parts of WinAD objects into a db to search from.I am trying to make this go a bit faster. there could be 10s of thousands of records to create.So i figured threads would do the job.I have tried straight of creating new threads for each db insert. that does not work for long, after 1700 threads it crashes.
t = New Thread(DirectCast(Sub() MySQLLib.group(dmn1, grpn1, grpd1), ThreadStart)) t.Start()
Is there a way in .NET (VB.NET or C#), when an exception happens, to dump the stacktrace of each thread? Basically I would like to reproduce what happens in Visual Studio's Debug->Threads window to see what each thread was doing when the exception happened
I know it sounds an odd request, but in order for others to gain access to an executable's VB.Net source code long after I have left the project I wanted to add something that could output the source code to notepad. This would be triggered by calling the exe with a numbner of parameters passed, like a pass phrase.I know how to pass the parameters and can call a proc based on what is passed, but I don't know if it's possible within that proc to dump the entire program's source code to notepad.
