VB has a function InputBox() that will prompt the user to enter a single value, then click OK. Is there a parallel functionality in ASP.NET, that will get the browser to pop up some kind of input box to return a single value? If not, how do you recommend I achieve this effect?
View 3 RepliesI don't know if this is the right place to start, but I'm using Visual Basic 2010. I'm doing the IMY Solution. Basically I'm calculating the new hours for each pay. The inputBox function allow users to enter the raise percentage. The problem for raise percentage is how can I set the name constant correctly. It asks to create a named constant for the "Raise percentage: " message.
Here is the code
Option Explicit On
Option Strict On
Option Infer Off
Public Class frmMain
' class level variable to enter percentage

Is their anyway to have the inputbox function reflect a password character while typing in a value instead of regular characters?
View 16 RepliesI have an assignment that asks me to:
1. create a button
2. when that button is clicked, an inputBox will appear to ask the user how many words they will enter.
3. then display an inputBox for each word.
For example, when the first inputBox appears, I enter "3" (meaning that I will enter 3 words).Then there should be 3 more inputBox (each inputBox allows me to enter only 1 word)After I enter the third word, there will be no more inputBox.How can we FLAG (stop) the inputBox, or let the inputBox know when to stop showing up?
I have VBA as a namespace in the vb6 code and i would like to know if there is a way of making .net know what there is, is there a specific application namespace? I have been guessing but haven't had any luck (the beauty of the help boxes, if only i knew more of the language)

Tell vb.net equivalent of following method:

I'd like to know if something like this pseudo code:

As a non .net programmer I'm looking for the .net equivalent of the old vb function left(string, length). It was lazy in that it worked for any length string. As expected, left("foobar", 3) = "foo" while, most helpfully, left("f", 3) = "f".
In .net string.Substring(index, length) throws exceptions for everything out of range. In Java I always had the Apache-Commons lang.StringUtils handy. In Google I don't get very far searching for string functions.
Edit:@Noldorin - My first encounter, although it took me several seconds to do the same in c#:
[Code]...
Note the static class and method as well as the this keyword. Yes, they are as simple to invoke as "foobar".Left(3). See also c# extensions on msdn.

View 3 RepliesI have an Excel VBA function that takes a number of optional parameters, including an optional Range:
Function DazBeta(A As Range, Z As Range, _
B As Integer, _
Optional Freq As Integer = 1, _
Optional c As Double = 0, _
Optional r As Range, _
Optional Pct As Boolean = True, _
Optional Label As Integer = 1)
I am translating to VB.NET, and it's the optional Range that is giving me grief because VB.NET does allow optional Ranges. Or rather, optional parameters must provide a default value. What is the recommended way to change the VB.NET function signature so that the code is callable from an Excel cell as a UDF? (The VB.NET implements a UDF, the assembly is registered as a COM server, and the Excel spreadsheet is told of this server and type library, allowing the VB.NET code to be called from an Excel spreadsheet cell.) I have other compilation problems, so I have not been able to explore this. I am thinking that accepting an optional Object (default value Nothing) might work and then I could cast the Object to a Range. Alternatively, if there were a default value that could be specified with an optional Range, that would work, too.
This question is similar to How to emulate MySQLs utf8_general_ci collation in PHP string comparisons but I want the function for vb.net rather than PhP.Recently I make a lot of supposedly unique key.Some of the keys are equivalent under UTF8 unicode collation.For example, look at these 2 key:
byers-street-bistro_38.15-79.07
byers-street-bistro_38.15-79.07
If I paste that into front page, and look at the source code you'll see
byers-street-bistro__38.15_-79.07
byers-street-bistro__38.15_-79.07
Note: In stack overflow they still look different.I know it's not the same. I guess even in stack exchange it doesn't show. Say I have 1 million such records and I want to test whether 2 string WILL be declared the same by MySQL UTF8 collation. I want to know that before uploading. How do I do that.So vb.net think that those are different keys. When we created mysql query and upload that to database, the database complain it's the same key. Just one complain and the upload of 1 million databases will be stuck.We don't even know what the hell is ? Where can we look that up anyway?Anyway, I want a function that when given 2 strings will tell me whether they will count as the same or not.If possible we want a function that convert strings into their most "standard" form.For example, seems to encode nothing and the function would recoqnize all those nothing character and eliminate that.Is there such thing?So far this is what I do. I need something more comprehensive.

Quick question on the InputBox. I am just learning this, what is the code to "read" commands that are placed from the Inputbox? I can do this in the command line: System.Console.Writeline(), System.console.Readline()
I just would like to know how read the line from the inputbox. Also when I debug my script do I -always- need to have the command prompt in the background?
I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --

View 3 RepliesHow do you make an Inputbox without a title?
I know you can do it this way:
inputbox("Please answer a question", " ", "")
This way you put a space in the Title property.
But is there another way to do this without putting a space in the Title property?
Maybe there is an inputbox without a title in vb.net?
