Assign The Value Of The Integer Returned From The InStr Method To A Variable

Jul 21, 2009

I want to assign the value of the integer returned from the InStr method to a variable. So, If TextBox2.Text = "The Apple Pie" And TextBox1.Text = "App", I want the integer returned, which in this case would be 5, put into a variable, lets say its called 'VarString'.
So VarString (would) = 5.

Search For New Line Position In A String Variable Using InStr

Aug 7, 2009

I have an application in VB.NET which gets string data from the database. This string has data which looks as below:

"This is the update: I have an issue with the application"

I need only part of the data, that comes after the new line i.e. "I have an issue with the application".

For this I am trying to search the position using InStr where the string has data in a new line. I tried many options, but they don't work.

I used "vbCrLf", Chr(13), "
", "
", "<br/>", Environment.NewLine, but none of them work.

How can I get the data I need?

Storing Multiple Words As One Variable To Use Instr() To See If Any Of It's Variable Words Are In The Text?

Jan 26, 2012

other than GML (Yoyogames.com Game Maker Language), I am new to the coding world. The only "major" project I have completed using VB is a computer calculator that exactly mimics the capabilities of Windows 7's calculator. Yesterday, I began a Chatbot program for my girlfriend. Lol. I have used the instr() function to answer most of the questions or answers which are typed into the textbox1. I find this extremely troublesome because when using the instr() function you cannot say instr(textbox1.

Public Class Form1
Dim fos As String = "Foster: "
Dim ash As String = "Ashley: "

Assign A Value To Nullable Integer Via A Ternary Operator / It Can't Become Null

Apr 19, 2012

If you assign a value to a nullable integer via a ternary operator, it can't become null..While this question may seem like a duplicate of many, it is actually being asked for a specific reason.Take this code, for example: Dim n As Integer? = If(True, Nothing, 1) In that code, the ternary expression should be returning Nothing, but it's setting n to 0. If this were C#, I could say default(int?) and it would work perfectly. Now it looks like I am going to have to ditch the ternary and use a regular If block, but I really want to use the ternary. If Nothing were truly VB.NET's equivalent to C#'s default, how can you explain this behavior?

Asp.net - Dealing With Data Returned By A Web Method As JSON With JQuery?

Jan 13, 2012

[URL] Using this I have managed to use Server Side Web Methods to perform actions with AJAX.In most instances, I just need it to do stuff (save things to a database for example) so don't need to do anything with the response, but now I've come across a situation where I do, and I can't work it out!The Web Method returns a JSON object, which looks like this:

{"d":"[{"validDetails":"True","lateAlert":"","LoginResponse":"Logging in Jamie at 16:53 please wait"}]"}

This is the output shown from Firebug. I am not sure what the 's are, but bear with it...The AJAX call and attempt at outputting this response is:

$("form").on("submit", function () {
var LogonObject = new Object;
LogonObject.password = $('#password').val();

[code]....

And several other variations from info I have found on Google and SO, but it seems to treat the results variable as a string, not an array, and the output I get on the alerts is each individual character, ie;

[, {, ", v, a, l, i, d, D... etc

So I wondered if results needed to be converted to JSON again (though I don't know why) so I tried

results = $.parseJSON(data.d)

But that didn't work either.

EDIT, the code which generates the response (missing out tons of logic, but this is the important bit):

Public Class OutputObject
Public validDetails, lateAlert, LoginResponse As String 'content of JSON output'
End Class

Use The ToString Method And A Counter To Concatenate A File Name Into A String Variable From The Image.FromFile Method?

Dec 18, 2010

I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

Assign Integer Values To The Items In 2 Different List Boxes Called LstWorkshop And LstLocation?

Apr 18, 2009

I am trying to assign integer values to the items in 2 different list boxes called lstWorkshop and lstLocation. I then want the equation, intCost = intDays * intLodgingFee + intRegistrationFee, to be executed and the result to be displayed in a third listbox named lstCost. This is what I have so far, but whenever I run the program the value that always gets displayed is 0, which is obviously not correct.

I get nothing but headaches when I try to update settings in the My.Settings class, or when I try to assign a newly assigned setting to a variable. Sometimes the settings update OK at run time; other times times they update only after the application closes; and other times still they appear to update at run-time, then when I close the program and reopen- they go back to the previous settings.This is how I assign a value to a my settings and how I assign a setting value to a variable.[code]

Assign To Variable If Inherits From Class .NET 2.0

I think I remember reading somewhere that it was possible to assign items to a variable if the item inherited from a base class, but I can't remember how.

I want to have a class that gets properties set and one of the properties is an error code property. I want to assign any exceptions that occur to the property, but it could be any type of exception. I remember that all exceptions inherit from the Exception class.

How can I assign an exception to a property based on the class it inherits from?
