Make A Textbox Choose What To Name A Variable?
Oct 19, 2010
How do I name a variable depending on what is in the textbox?
Like would it look like:
Dim (textbox.text) as string
etc.
The reason I want to do this is because the user is gonna click a button to create a task. When the button is pushed, a label is created by the code I already have, the problem is, I want them to be able to click the button more then once and new labels will appear below the one that just was there. By being able to name a variable by what is in the textbox, I will be able to do so many things.

I am using VB .net 2010 express from microsoft. I have a numeric up down box to display a variable that the user can choose a number for. Then I have a text box that I want to display a result of the updown box * 1.5... So far I have the following... What do I need or need to change? I have the integer variables initialized or whatever with Dim statements as follows -
'speed variables
Dim CruisingSpeed As Integer 'cruise speed - updown box
Dim FlankingSpeed As Integer 'Flanking speed - will be cruise * 1.5
[CODE]..................
It says that it cannot convert the up down box into an integer... I need it as an integer to calculate the other number...
Complete code just in case the above was not enough info...
'Imports Excel
'Imports System.IO
Public Class Form1
[CODE].............................
I have some stuff commented out because a variety of issues - some I will end up using and some I will end up taking out before it is done...

I have DateTimePicker where user can choose a date and make entry. I then record this entry into the database. My application date shows 08-02-2012 (i.e., 08 february 2012 in DTPicker value), when I select this and insert it to my database, the MS Access takes this as August, 2 2012, and records it as the same.
I could fix this by using this code:
Dim mydate As DateTime
mydate = Me.dtpicker10.Value.ToShortDateString
Dim output1 As String = Format(mydate, "MM-dd-yyy")
and pass sql insert query using
insert into table (mydate) VALUES (#" & output1 & "#)
Instead of getting the value directly from the dtpicker. This fix the issues, but when I tried to get the date out of the database to filter it between entry made in certain date, I sometimes have problem. How do I generalize this for all type of client computers where the date and time settings can be any form. What will be the best and more flawless ways of approach to target all types of clients? Am I on the right track?

I am currently working on a family project which is based on "Who Wants To Be A Millionaire?" show. There is a huge diffrence between the show and my project. My project is a christmas edition and the goal is not to get money or something, since I will not add it... Erhmm... Let me get to the point. I have already designed a layout and scripted some things. I have about thirty questions but I do not want them to always spawn in the same array, if you know what I mean. I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D. I have got everything, I just need a code.

I have a VBA form in Microstation I am using to try and help automate a task. The only problem I am having is I am reading a textbox (Filebox.Text) and setting it as the variable (FN). It works, because I used Msg.Box (FN) to test it. However, in two of the lines of code, I am trying to use (FN) to pass the typed in filename to the command to run in Microstation. Unfortunently, it gets passed on as (FN).dgn instead of the actual filenale typed into the textbox. Is there a way I can make the variable actually seen as a variable? Code on Pastebin: url....Also, not sure if this is the right section, 100% new to VBA, coming from a world Bashed together.

have the following code and would like to know how I can substitute the filename (i.e.,test.rtf) with the name of a Textbox. For example, I have several Textboxes that I want to add and associate individual comments to. That is, once the comment is created I will SaveFile with the TextBox name. Each of these Textboxes will have their own comment

I posted this before and got a few answers that haven't worked for me so far. Therefore I'm going to post part of my code so you can see what I'm talking about. The highlighted part is what I pulled from another post and it's not working for me right now. I'm using visual studio 2008 and the program was written in Basic. I pulled most of this program from the net and started tweaking it to my needs, If you're familiar with arabic you will understand the letters, if not, just use A and B for the variables.

Well, my problems is follow. I use a textbox where the user can enter a text but which I would like to prefill out with a variable (later , with more experience, want to ask the AD for the username and put it in the box).
That means, when the user runs the app, automatically is the username written in the textbox without pushing a button but the user has the opportunity to change it (For example doesnt want the second surname).
