That also doesn't work.And the most odd thing about all this, is that the passwordtextbox is getting is value from pass_desincriptada.
I've setup a login form on an app I am building and I am using that to pull back user details from SQL @USername, then comparing the password on SQL to the one typed into the login form. The username and password get pulled back from SQL and fill two text boxes which are hidden from the user under a logo image (I haven't actually set them to visible = false cause I've had that cause errors itself with other things before)
Code on the Ok button on the login form:
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click
Dim UserLogin = Trim(UsernameTB.Text)
Dim UserPass = Trim(PasswordTB.Text)
If String.IsNullOrEmpty(UsernameTB.Text) Then

i have made a program that needs a password to activate it but i would like it to look for a text file in the same directory called "password.text" as it will alow me to change the password.

I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time.Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?
View 3 RepliesI try to read the ID3 Info from a .mp3 file by reading bytes, and then i convert it to a string, and try to compare it to a string (that contains the same word(s)) but wasnt a byte stream beforehand anyhow ALL of my converted strings have a length of 31, regardless of if its a string that says "John" or a string that says "Teenage Mutant Ninja Turtles" how can i make my converted string have the correct length?

View 8 Replieshow to Compare text box text with listbox items text in vb.NE
View 3 RepliesThis might just be a matter of taste, but I'm wondering if there's a "recommended" way to compare a variable of type Object (which might be Nothing or have a different dynamic type than String) to a string literal in VB.NET. The following options obviously won't work:
If myObject = "Hello World" Then ... -- won't compile
If myObject Is "Hello World" Then ... -- tests for reference equality, which is just wrong
If myObject.Equals("Hello World") Then ... -- throws an exception if myObject is Nothing
If DirectCast(myObject, String) = "Hello World" Then ... -- throws an exception if myObject is not a string
Thus, the only (simple, single-expression) solution I could find is to use
If "Hello World".Equals(myObject) Then ...
which looks a bit clumsy to me. Did I miss any obvious alternative, other than doing type checks or explicit checks for Nothing?(Of course, we're talking about Option Strict On.)
I am making a app that reads options of a ini
dim config as new iniconfigsource("patch.ini")
dim test as string = config.configs("news").getstring("test")
Then I made a dropdown with options
I want my script to compare the values of the dropdown with the string readed from the ini
then uses it as selected value (the so called standard value) the one uc without clicking on the arrow if the none of the values match with the string value of the ini then it executes
dropdown1.selectedindex = 0

View 7 Repliesafter slicing and dicing, i got 2 vars with the following values in vb.net:
strTag = "<#<span class=SpellE>vermittler_person_Name</span>>"
tmp = "<#<span class=SpellE>vermittler_person_Name</span>>"
Comparing the vars gives a false:
strTag = tmp ' ==> false
Comparing the values directly right there gives a true:
"<#<span class=SpellE>vermittler_person_Name</span>>" = "<#<span class=SpellE>vermittler_person_Name</span>>" ' ==> true
Both are strings, i tried all kinds of stuff: string.compare, string.equals, also regex etc. etc. everything works perfect with all the other strings with simlilar structure, just not and only not with "vermittler_person_Name" in the middle...
I have a dataGridView and a textbox on a form. I want to be able to search through the dataGridView and sort it compared to the string in the text box. Ex: I type "acv" in the text box and all strings containing "acv" are sorted to the top. I'm accomplishing this with a bunch of gymnastics involving datatable.select and some clearing and filling but it's ugly and slow.
View 2 RepliesI have 2 Text Boxes containing lists of names and I have a 3rd text box which I would like to use to determine the names that are missing from textbox2 that are listed in textbox1.
Textbox1 is: Customer
Textbox2 is: Closed Sale
Textbox3: is Sale not finalized
Would be great if it could auto populate into textbox 3 if not I will just use a button to action the function. First crack at dabbling with VB and whilst googling has managed to aid me in many ways unfortunately sometimes it is difficult to find relevant threads.
Does any one know how I can compare the numeric value of a text box on my Visual Basic 2008 form to the values in a particular column of a SQL database table? Things seem to work fine with bound controls when there are related records in the child table, but if a value is selected that has no related child records the form continues to display old information from the last record viewed. I would prefer to have the fields on the form go blank.

View 1 RepliesI am trying to use the Boot log and I really don't have much experience with parsing and comparing. What I need to do is to get only the minutes and seconds time stamp from a string similar to this from the boot log
Did not load driver SystemRootSystem32DRIVERSsrv.sys
Loaded driver SystemRootsystem32DRIVERSMpNWMon.sys
Microsoft (R) Windows (R) Version 6.1 (Build 7600)
4 11 2010 23:40:47.375
Loaded driver SystemRootsystem32
tkrnlpa.exe
Next once I get the minutes and seconds subtract 5 seconds
Next compare the resulting minutes and seconds to the minutes and seconds from a second file and display the result
EXAMPLE: If you take the minutes and seconds from above 40:47 - 5 = 40:42.
Next you get the minutes and seconds from the second file and you get 40:59
So you wind up with 40:59 - 40:42 = 00:17

View 1 RepliesIs it a good idea to store the database pasword in our code like below?If it is not why and which is the correct way to do it? I do not prefer the password to be inserted evrytime the application starts either
conn.ConnectionString = "Data Source=Z:LearningsMyDatabase#1.sdf;Password=abc"
Using VS2010 I am adding a new data source (SQL Server for this app). The wizard asks if I want to include sensitive information (e.g. the password). In this case I answer "no" ecause I don't want the password showing up in the Config file (the rest of the string is fine).
View 6 RepliesI want to encrypt all users' password that stored in database, but also i need to able to decrypt them.How can i do that?Because i try using MD5 method and only get one way ticket
View 4 RepliesLet's say I have the following string:"/encryption:aes128 /password:<PASSWORDHERE> /log:log.txt"
I need to write this to a log file but the password needs to be masked (replaced with asterisks for example).I can do this easily with String.IndexOf and String.Replace in a few lines of code but I'm interested in seeing how others would implement this so that the code is as short and concise as possible. A one line replace function would be best.
My goal here is to see/learn some new techniques of combining string functions.
Note that I am not interested in using a RegEx.
I have a problem with the code below as a SQL command string. Note: Using .Net Framework 4.0 in Visual Studio 10 Professional. Database is a Microsoft Access file. The idea is that this SQL command string will update a password within my database. Also note that I have tried the string below with and without the ";" at the end and it does not work either way. The problem is most likely extremely obvious, but I can't seem to find it. I have commented below the code what each part of the String is.
"UPDATE Users SET Password='" & tbx1.Text & "' WHERE Username = '" & sUsername & "';"
' Users is my Table name within the Database.
' Password is the field that I want to edit within the Users table.
' tbx1.Text is where the password is stored within a text box.
' Username is the field which I would like to compare with sUsername which is a variable within the code.
Solution was square brackets, Command string now looks like this:
"UPDATE Users SET [Password]='" & tbx1.Text & "' WHERE [Username]= '" & sUsername & "'"
What would be the fasted method of get a string list of all values within [] in a string of text? For example: [client_name], are you are doing today? My name is [my_name]. The list of strings would be:

Does anyone know how to store the connection string in a file rather than hard coding it in the application. For example i have declared this connection string in the form to connect to oracle database and it works. But i assume this is not the right way to go by if one is looking for more secured environment.

I am writing a program to be able to input a password and take that password and display a new password in a label. the new password will display the results as follows. Any vowels in the old password will be displayed as an x in the new password and numbers will be displayed as x's, and the last part it will display in reverse order so if I enter in timmy1 it should display zxmmxt. I do not know how to write the code to be able to reverse the string to be able to display the password backwards.

i need to be able to compare data from a text file with the collection of a combo box.My algorithm currently populates the combo box with data from the text file on the form load event.I have included an update button that updates the combo box collection.[code]
View 1 RepliesI have an application that currently operates based on a static password that is hard coded into the application. I would like to somehow have the application look in a text file, say: C:passtest.txt for a password. The text file will have nothing but the 1 password in it, it is just to make the changing of the password easier than having to recompile it everytime.
This is in VB.net. Also, there is no required user name for the application, just 1 textbox (TextBox1) that asks for the password.
I suppose the application (upon startup) should read the text file, grab the password, and save it into a string variable called "password".
