Convert Code To Class Function?
Mar 6, 2010
I am new to vb.net and would like to be able to convert the following code to it's own function - either inside the current module or better yet in a seperate class.This code currently runs in the KEYPRESS event and ensures only numbers, decimal point, 2 decimals etc. are entered and not letters. Works exactly how I want it but would now like it in a function.I need this code in numerous text box controls but I would rather just call it somehow with a function.

I have some C# code I'm trying to convert to VB.NET. There are some external dependencies I'm referencing in each project. The C# line is
TWriteFileCommand writeFile = (TWriteFileCommand)CommunicationLink.CreateCommand(TOPKernel.TCommand.CommandType.WriteFile);
I don't really understand what the TWriteFileCommand in parathesis after the equal sign is for in that statement. When I try to do it in VB.NET, I keep getting errors because I can't get a reference to the CreateCommand function. The closest I've gotten is this:
Dim MyAppBase As OPSupport.App.AppBase
Dim writeFile As TWriteFileCommand
writeFile = MyAppBase.CommunicationLink.CreateCommand(TOPKernel.TCommand.CommandType.WriteFile)
However, I have a green underline after the equal sign @ MyAppBase that flags an error "Variable MyAppBase is used before it has been assigned a value. A null reference exception could result at runtime."What am I missing? Why in the C# code is the instance fine and what do I need to get the equivalent instance in VB.NET?

I've been having trouble converting the following fairly straight forward c# code into vb.net 4.0, which I understand has anonymous delegates. I just havn't been able to figure it out yet.
_combo.DataBound += (sender, args) =>
{
var item = _combo.FindItemByValue(values[0].ToString());
if (item != null)
[code]...
I have tried the following
_combo.DataBound += Function(sender, args)
Dim item = _combo.FindItemByValue(values(0).ToString())
If item IsNot Nothing Then
[code]...
But the compiler complains that DataBound can not be called directly, but has to be called with RaiseEvents

I've got a class hierarchy similar to the following: Animal is abstract, Dog and cat inherit from animal.
Is there a best practice for converting / casting a dog to a cat? Of course there may be dog specific properties that won't fit in a cat, but they share several properties that they inherit from animal. Just curious what people think. I'm thinking reflection could come into play, but I wasn't sure if anyone had experience with this.

I have a very simple class that is located within my App_Code folder in my VS2008 web application project. I am trying to instantiate an instance of this class from my code-behind file. Intellisense does not seem to be seeing my class and I am not sure why. I am using VB.NET which I am admittedly not that familiar with as compared to C#. Perhaps I am missing something. I would bet it has something to do with something I am missing in VB.NET.Here is my simple class (for testing):

This is my first time writeing a program and i am stuck. i am just looking for were i should go next. i can't figure out how to write in code for the days in the getDay function.
Write a program that computes the cost of a long-distance call. The cost of the call is determined according to the following rate schedule:
a. Any call started between 7:00 A.M. and 9:00 P.M., Monday through Friday, is billed at a rate of $0.30 per minute.
b. Any call started before 7:00 A.M. or after 9:00 P.M., Monday through Friday, is billed at a rate of $0.15 per minute.
c. Any call started on a Saturday or Sunday is billed at a rate of $0.10 per minute.
The inputs will consist of (1) the day of the week, (2) the start/end time of the call, and (3) the length of the call in minutes. The output will be the cost of the call. Input will come from the user and outputs will be displayed via the console window.
Module program1
Sub Main()
Dim day As String
day = GetDay()

I recently found this code (provided for third party use on another VB site), however,ll of my attempts to insert it into a class library have failed.I open a new class library and past the code in, and immediately get several errors pertaining to how certain objects can't be found. I find it it is crucial to use this code, unless someone can suggest to me another example of existing code that will do the same thing: make a restricted textbox who imputs can be restricted, that can handle pasting, shortcuts, text property setting, and script-entered text.
Option Strict On
Imports System.ComponentModel

only code I can find after several hours of searching is a PHP function. Although I can more or less see what's happening, I'm not able to convert everything. The main problem is the "temp_getBytes" function. I don't know how to convert that.I already have the file as a byte array, because it was decrypted, so I'm writing the byte array to a memory stream in order to work with the data. I've added a bunch of question marks where I'm having a problem converting the code.

I've more or less finished the design of the interfase, but there are stange this happening with the form. I can say much about what is wrong because I dont understand it, but I would like to. I have added the form Class code and the Designer Code, is that enough or is more required? Theres a msgbox that popup in the form Load event which I placed there to see what I could learn about the GraphicsBuffer.

I'm trying to convert C++ API to VB.Net, but this function is too hard and i don't know how make it work.
Here is the API doc for this function:
void RemoteDllSetReceiver(void *inst, on_received_buffer_t received_buf_cb);
Sets a callback function to receive notifications from the DLL. The prototype of the callback is:
typedef bool (*on_received_buffer_t)(void* inst, const unsigned char *buffer, unsigned int size);
Where inst is the pointer originally passed to RemoteDllSetReceiver buffer & size contain the notification text as defined in the Remote Protocol. Note: notifications may arrive in different threads (e.g. network, timer, audio).
I can't imagine what i mus do with on_received_buffer_t, must it be a delegate? Like you can read, this functions returns notifications from the DLL like connection status, user id...
