I am using following code to run a private function. I have two values in my combo box, One and Two and two private functions with the same names, Private Sub One() and Private Sub Two() I want my application to call the function whatever value user choses in the combo box. If One is chosen in the combo box, Private function one should be called. Thanks Code is below, that does not work
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim vrValue = ComboBox1.Items(1)
I need to build an application that could run code in private function, based on what user has selected using combobox. For example combo box has three values, One, Two, Three. If user selects one, code written under Private Function One() runs and vise versa.

I have a Form that includes ContextMenuStrip1 and PictureBox called "PicBoxBack".How can I call Private Sub PicBoxBack_MouseClick from the ToolStripMenuItem_Click Procedure??[code]
I have a form (frmMain) that contains a custom control (con class). frmMain contains a combo box control and when the user selects a value from it, I pass this value to a sub routine within con class (see red line below). This purpose of the sub routine is to populate a set of comboxes contained in con class according to the value that is passed in.
Private Sub cboGuidelines_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboGuidelines.SelectedIndexChanged If bChanged = True Then
I am trying to create a sub routine that I can use to clear all items on various ComboBoxes on a Form; this is the code I was trying to use [To no avail]:
Public Sub Clear_ComboBoxes(ByVal ComboBox_Name as String) if Controls(ComboBox_Name).Items.Count > Nothing then Controls(ComboBox_Name).Items.Clear end if End Sub
I am writing the code on a seperate module to the Form; which means I can't use ME.Controls; but Form_Name.Controls doesn't seem to work either.
if for example i have two private sub I declared a local variable on private sub a... is there a way that private sub b could use the variable created on private sub a? Im asking because im in a problem in my app were using global variable is not an option to make the long story short
I don't know how to make button1 call the combo box Items to do a conversion calculation for the following:
From To Conversion Miles Kilometers 1 mile = 1.6093 kilometers Kilometers Miles 1 kilometer = 0.6214 miles Feet Meters 1 foot = 0.3048 meters Meters Feet 1 meter = 3.2808 feet Inches Centimeters 1 inch = 2.54 centimeters Centimeters Inches 1 centimeter = 0.3937 inches
Attached is the Form that I am working oo Public Class Form1 Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged ComboBox1.Items.Add("Miles to Kilometers") ComboBox1.Items.Add("Kilometers to Miles") ComboBox1.Items.Add("Feet to Meters") [Code] .....
I'm trying to call the windows properties page of a selected network card from a combobox, so it shows the current settings of the selected networkcard. I mean, like if someone would go to the network settings - right click on the appropriate connection, and go to the properties. For a file properties, one can call the properties by using the shellexecuteinfo function.
explain me the difference between them? I'm new to visual basic, and I need to know the very basic things in Visual Basic allowing me to become a professional User
I am pretty new to VB.Net and OOP in general and am picking stuff up every day, but it is so easy to become burnt out with the sheer amount of info. Therefore I am taking it slowly. Yesterday I was reading my book and read that using Dim for class level variables is allowed(if the compiler is set so) but is bad design and I should instead use Private. Dim defaults to private anyway. So my question is where should I use Dim instead of Private?

I have a "Main" module that is sort of the "brain" or "top level" of my project. Basically, I think there are routines that it only should be allowed to call. Some of these routines are in other modules, so I don't know how to make them hidden to everything except the Main module. If the routine is ublic, anything can call it; if it is private then the Main module can't see it. Also the other modules are big enough that I don't feel it would be a good idea to stuff them completely inside my main module. How can I achieve this "private except in one place" functionality?
I'm looking to use RSA Asymmetric encryption to encrypt some data. I've read this article on the forums with a similar title, but it did not answer my question. What I would like to do is use the private key of an RSA key combination to encrypt (sign?) the data and use the public key to decrypt (verify?), as per this wikipedia article . I would like to use this method because I want people to be able to read the data, but not create it themselves. I've copied the code from Peter Bromberg's article RSA Encryption in .NET Demystified , but always get an exception with the "Bad Key" message. If I use the public key for decryption, it works fine (the opposite of what I want). use the public key for encryption.
how to make projects which span multiple files and classes just fine. I've had big multi-file things working.I've been told explicity that my classes have to be private...yet at the same time I'm supposed to have a main method elsewhere and somehow call a menu in my main working file.I can get the program working perfectly when I do it in a logical manner but I just can't figure out how to call a private sub. I keep getting the error reference to a non-shared member requires an object reference.I've tried breaking the rules a bit and making one initial sub which is public, shared, etc... but all this does is delays the error until it tries to call its first private sub.
I don't suppose there is a VB equivalent to a property's {get; private set;} in C#? I get errors if I try to make the Set private (I also need the property to be overridable). Readonly is the closest thing i can think of, but this does not work with my situation (working with NHibernate).
So I created this thread: Invoking Private / Protected Methods Via Reflection From The Same Object Instance (or Base) And we got the problem fixed save for private methods. As this may not be the same issue I thought it may be best to post a different question with the full source. It is still a work in progress but it is functional.
[Code]...
So this class is being inherited by a (so far) empty child class and ProcessStage is being called. Notice that ConfirmFormDataIsValid() sub is private. If you run this it will not find this method. If I change it to protected however it works fine.
I am trying to create a signature from a private key that i have been provided and a hashed value. I am using DSA and the following code but receive the following error:
Invalid type specified. source mscorlib
The error is thrown on this line: ImportCspBlob(pk)
Private Function key() As String Dim privatekey As String = "-----BEGIN DSA PRIVATE KEY-----" _ & "Key Data"
I'm using the .NET version of BouncyCastle, and I have to save a private RSA key to file, obviously encrypted with a password for security reasons.What I'm trying right now is this:
Dim rand As New SecureRandom Dim arr As Byte() = New Byte(7) {} rand.NextBytes(arr)
[code].....
But BouncyCastle is thwrowing a NullReferenceException on the last instruction. Since the method is totally undocumented >:( I wonder if any of you know how to use it correctly...
i want to add calculations in 1 private function I have a textbox named lbldisplay.text when i enter a number.. the number is shown as a string so.. -private number1 as string when i press the button "+", "*", "-", or "/" the number1 must return into a double. So the number in the textbox is now a double.. so for example i press the + button, and i need to fill in a new number.. but this new number is also a string!
