After the 7th line I need a pause until a submit button pops up on the screen. The submit button is hidden until the getelementbyid.focus is run. I cant use webbrowser_documentcompleted because the submit only unhides itself, and I cant use Sleep() because that just stalls the whole block.
Does anybody know the code to refresh and reload desktop icons, you know how after installations of programs it sometimes refreshes the desktop? That is exactly what I need and what I am looking for. Someone please help me out here because I tried searching on google and could not find any proper code.

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 found a function in C++ that I would like to call in VB.NET, but I don't know how to do it. I was reading some forums and they said you had to create some sort of wrapper or something like that :8-0:This is the function I need to use, and it comes from microsoft's page here. Basically, it returns all the loaded DLLs for a given process ID.
I wanted to to something like this:Code:Dim myProcessId As String = '1234'Dim myModules As New List(Of String)myModules = getProcessModules(myProcessId)' ^ I know right now the C++ function doesn't return anything (it only prints) but I don't know C++ so I'll have to try to change that later.
Code:#include <windows.h>#include <tchar.h>#include <stdio.h>#include <psapi.h>
void PrintModules(DWORD processID){ HMODULE hMods[1024]; HANDLE hProcess; DWORD cbNeeded; unsigned int i;
//Get a list of all the modules in this process. hProcess = OpenProcess( PROCESS_QUERY_INFORMATION

don't use ACCESS, EXCEL, or a TEXT FILE as a database. If you want your program to use a "local database", without any of the hassle of setting up a MS SQL or MySQL server, just click this link: >>> SQLite <<< Seriously.

I remember that C# editor has a powerful option that when we are developing in code and type a new method (operation) name for a class, we can create its body by clicking on ALT+Shift+F10 and immediately, it will be created for it's own class.

I am creating a VB 2010 program that lets your select the program(s) you want to install (chkbox) and hit run. Then have it launch the installer ( the file is across the server) and accept the predefined keystrokes to proceed through the installation process. Afterwards, it starts the next install. Below is the code that I have. What i cant get to function is the unit accepting the keystrokes, its almost as if it wont take focus ( even when i have used Appactivate and threading.thread.sleep). I have even gone so far as to identify it as a process to manipulate the thread. To be honest, i'm at a loss and need any help at all. The final sub that contains "btntest" is where I am at currently in my attempts. [Code]

In my project, there are 3 user controls; BasicContact, BasicDetail and ActionTime. They are in EditOrder.aspx page. There is "ReportDate" property (Date type) in BasicContact, RadioButtonList "rdl_Priority" (with integer value from "prio_id" field) in BasicDetail and "CheckDate" property in ActionTime. The ReportDate value is derived from txt_ReportDate and txt_ReportTime and CheckDate value is derived from txt_CheckDate and txt_CheckTime.

I have a MustInherit class with some MustOveride Methods in it. When i inherit form that class, I automatically get the MustOveride Methods or properties.

I've once seen a .net class that did it, when I inherited from that class, I got the methods, with some comments in it.

View 2 RepliesI 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 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.
