I've tried to make a program whereby the input affects a variable.

I am new to VB.Net and programming all together. I am trying to make a program that will take 2 numbers input by the user, Add them together and display the sum. Then take the sum and divide it individually by each number to give you what percent of the sum the numbers are. I'm working on making it a program that will calculate the Hardy-Weinberg equilibrium for my Anthro Class. I'm just doing this for practice for my VB.Net Class. But i will move onto that at a later time. I just want to finish this first.
So.. Here is my code so far. It's not complete yet but this is should be enough to make it function.

i want to make a program in which the user can input a mathematical function so the program can then work with it. So the user would input something like x^4+x+2 and then an x and the program would calculate f(x). What i don't know is how to let the user input the function.

I have a program for school project that has input fields for Name, Address, City, State and Zip. I need to error check so that the fields are not empty.I have used If statements that check to see if the fields are empty and shows a message box if they are but if I leave the whole form empty and click the button that activates it, all the if statements go- one by one instead of pausing for the user to input the required data.How do I check for data and make the program stay there until the data is input? I have tried TRY/CATCH but it won't catch this type of error.

I am working on an app that is an MDI. When the user clicks a button on an MDI child, I want to "disable" the current MDI child (and only the current child window), open a new window that has control, and then re-enable the child window when the new window is closed...very similar to using showDialog(). The thing I an having trouble figuring out is how to allow the other child windows to be active at the same time as when the new window is open. If I use the showDialog(), all child windows are disabled
View 8 RepliesI'm wondering if there is a way to write a code that affects every single TextBox in my application... I have about 12 Forms that are all inherited from my BaseForm. I want to affect all of the TextBoxes in those 12 forms The idea is, that every single TextBox would change the text in it to Bold, if the text is not 0 or 0,0 or 0,00. Let's say there is a Form that has about 100 textboxes to indicate different values. Every TextBox that shows the value 0 should be in normal font, but every TextBox that shows any other value should be bolded...
Or should I just do a public function that is called every time a textbox changes value? (Not quite sure how to do this either...)
In teaching myself how to use databases in VB applications, I've managed to
1. Get list box data bound to a database
2. Filter number of items displayed in list box based on user input (letter entered as a filter)[code]...
How can I now have it so that the user selects an item in the list box, and then text boxes on the same form are populated with the relevant data (i.e. database fields matching each text box, with another field from the same table having already been used to populate the list box)[code]...
I am currently creating the classic Pong game in VB.Net. I have a few questions regarding angle of approach and rebound.
For example if the ball hits the wall at roughly a 30 degree angle then it should roughly bounce off the wall at ~30 degrees. This is my first query, how would I achieve this as I cannot figure out how. It is currently bouncing the ball off the wall by altering ballXspeed and ballYspeed by 5 or -5.
My second query is that of the ball hitting the paddle, if the ball is to hit to top 0% - 5% of the paddle it will bounce off at a different angle opposed to if the ball hit the paddle in the 15% - 20% zone of the paddle.
Here is my code in its entirety:
Public Class Form1
Dim ballXSpeed As Single
Dim ballYSpeed As Single
[CODE]...
I understand that you cannot do the work for me and I don't expect you to. Would it be possible for help with the pseudo-logic or a particular area. I forgot to mention that the ball currently bounces off the paddles at a random angle.
Hence:
ballXSpeed = -5
ballYSpeed = New Random(DateTime.Now.Millisecond).Next(-10, 10)

The variables in the brackets [example] do not actually have brackets in them in the original code. These are where the issues are. For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')." Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.
-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop.

View 1 RepliesSay I've got the following variables:
Public Shared x As String = "100"
Public Shared y As String = "text"
Public Shared z As String = "something"
[Code]....
But this doesn't do what I want, naturally. What I want is that my function giveVar returns the value of the variable that holds giveVar. For example I call giveVar("x") I want my function to return "100".
Of course this can be done by a Select Case but thats not what I like to do. Is it even possible to call a value based on a string?

I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

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.

I want to hear some discussion regarding what is the best way to persist program parameter and variable settings from one run of the program to the next. I used to often use the ubiquitous INI type file in VB6 programs but I am aware that these are not formally supported in .Net programs. I also have a major aversion to adding to the already overwhelming bloat of the Windows registry by using that to store values.
