Loop - Get The Variables To Change Value To The Updated Day?
Oct 3, 2009[code].....
This program asks the user for a number and then an amount to multiply it with and that amount should be added to the initial number. I need to loop because I am trying to display what the amount would be each day for a certain amount of days but in this loop its only calculating for the total .how to get the variables to change value to the updated day. I understand that its just keeping the same value in the variables I just need a push on how to get it to update the values through each loop.
Accessing And Creating Variables Inside A For Loop?
Oct 15, 2011I have some variables that are distinct by numbers, like in1, in2...If I have for loop, how would I access those variables, using the counter, and attaching it to the variable?I believe in JAVA, you could just use in+ct... where ct is the counter to access the variable.also how could you make a new variable in the for loop?Initially I had variables declare outside of the for loop. The problem was how to access those variables using the for loop.
var_nm1 = in1.Text
var_nm2 = in2.Text
var_nm3 = in3.Text
Dim nmList(2) As Integer

This is object oriented programming, and I made the textboxes in1, in2, and in3 using the GUI editor. that was so easy.
Change Increment Variables Causes For Loop To Go Over Limit?
Nov 4, 2010In my loop I am trying to remove items from a list that have a certain name. I can't do this with a for-each, so I tried a regular for-loop.

I'm trying to find the correct way to accomplish this. [code]...
View 1 RepliesPlotting In A PictureBox Within A Loop And Passing Variables?
Feb 24, 2010This is my first attempt at doing something in VB.net. I would like to be able to read a text file consisting of a column of data values and then pass the data as a variable to a sub that produces a line graph and updates it with each iteration through the loop. So far I have the code to read the file as well as some code that produces a line graph using hard coded values.
I am unsure how to call this sub from my loop such that I can pass that data value read from the file to the graphing sub.
How can I call the "PictureBox1_Paint" sub from my loop? How can I pass variables read from the data file to "PictureBox1_Paint" when I am calling it? Is there anything different that needs to be done if I want the graph to update with each iteration through the loop (for each data point)?

Multiple Forms, Variables And So On?
Oct 24, 2011i would like to say i am a novice programmer, in year 12. I am designing a small game for my HSC and one of my forms is getting very cluttered with controls and code. To resolve this cluttering, i have had the idea to create new forms for some aspects of the game (such as different game modes and so on). However, in order for that to happen i have to drag some variables of the new form to the old form, (these variables would be just booleans or integers to say whether you lost a game or won a game or something that would carry on to the main form.)

Preserving Variables To Use On Multiple Forms?
Sep 25, 2010I am trying to have it so that when a user hits a button to enter a shop, it will open a popup window which will have the shop's goods. The only problem is I can't figure out how to keep the variables working between the two windows.
I need to get the variable 'gold' to transfer to and from form2(the shop window) and whatever is bought at the store to transfer back to the main window.
Right now, when I go to form2 all the values are 0, and all the variables I used on form1 are undeclared on form2.
How do I access variables from form1 to show up in form2? Is there an easier way to accomplish this than using a separate form?

Saving Multiple Variables Of A Type To Be Loaded Later?
Jun 12, 2011<pre-question blab>// skip if you want Might as well consider me new, as I haven't programmed in years, and that was only tinkering in Java. Trying to get back on track a bit, so starting with VB to get the feel going to continue learning. I don't mind putting in the effort to learn and look up, I just am not 100% sure what I should be looking into at the moment... Old programming I did was nothing advanced, only little things like calculators, notepad-esque writers, and that sort.</pre-question blab>
I'm BASICally wanting to know what I should look into for saving multiple variables of a custom class object to be loaded later. I've seen some things about text, and I can do that fine, but don't think it would be the proper/best way of handling things
at all. I also saw some talk of XML, SQL tables, etc. I just need a point in the right direction.
For a bit more info on my actual project, I was tinkering with a 'simple' program to allow users to create rooms/objects/etc., which will then be converted into Inform 7 language (an interactive-fiction language).The variables needing stored are objects with a number of string variables and integer variables. I need to be able to save those, then load them out later into an array of said objects.
For anyone needing a more VISUAL image of what I mean, here are a few screenshots to show you what I mean. Also, if anyone has ever used Adrift, it is (at the moment) very similar to it, but for the Inform language.
