If I typed in "Dim X as Integer" in a text box, I figured that I could just use If TextBox1.contains to make vb.net dim it. However, how would, if I typed "X = 3y * 9" in the text box, actually calculate that and print it in another text box?

i want to find the last index of "," in my text and then remove that , but it is not working. Any Idea? txtBeautified is a richtextbox.
I'm using a Microsoft Word form template to create objects in a form programatically, so depending on the information read by the program from the template.
So, I've got some fields where I store formula data for the form, in which I specify that the value for that field is obtained by multiplying other fields in the template. So I store in the string something like this:
"Text1.Text * Text2.Text"
So I need to convert these string values into variable calls to actually operate these values.
I am a beginner trying to write code. I am creating an application that is a questionaire with 3 forms that have questions for the user with text boxes, list boxes, and check boxes for response. Some of the text boxes with the user response are on different forms. Will that cause me problems? I would like to write code that will combine a literal string with responses from text boxes and string snippets which are inserted based on check box condition. I think I would like to create the string to be printed to a RichTextBox and then output to peripheral printer. How do I make inserting or not inserting a string based on check box condition? How can I trim the response string to allow a output string without annoying extra spaces and such?
View 3 RepliesLast year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.
I have a arraylist or array, the data is below
aa/bb
aa/bb/cc
aa/bb/dd

I seem to be running into an issue. This may seem like a noob question (which it really is, I only have experience in vb6 from years ago) but what Im trying to do is pass a variable from one form to another. Ive tried telling the first form to set the value of the variable on the second form like so frmsecond.variable = "value" but that does not work. Ive tried placing a public variable in a module to do it, but again, no luck. The only way seem to be able to get it to work is the second form setting the variable by reading the value from the first form like so [code]The problem I have with that code is what if for some reason the selected line gets changed as the form is loading or something to that nature. It doesnt seem very secure.

View 6 RepliesI have an interface that i have declared some of the basic internal functions, subs, properties, etc. This interface is then implemented into 3 pre-defined classes. These classes are end-use classes so they dont get derived or inherited elsewhere. I am trying to create a generic shared class that can operate on each of these 3 predefined classes and potentially more as long as they implement the interface.

I am having trouble passing variables between forms. Ive tried many methods but none seem to work. The first method I tried was to dim a public variable on the first form and call it on the second....no success
Form 1:
Public cliCode as string
cliCode = me.tbClientcCode.text
Form 2:
dim clientCode as string = form1.clicode
or
Form 2:
dim clientCode as string
On the Form2 load event....
clientCode = form1.clicode
With method 2 I created some classes on which form 1 loads and form2 access........
Public
Class frmClient
Private db As New ClientDataContext
Public clientInstance As New BusinessLogic.classClient
Public cliCode As String

Is it possible to share subscripted variables and their data between forms? So far I can't see the variables I made public in one form, in a second form.
View 5 Repliesi 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.)

I know this should be easy but I'm either having a brain fart or I'm just more inept than I thought; probably a combination of the two.
Passing a value to a form on startup is a piece of cake, but I don't think I've ever had to do the following before in all my ooooh, 8 months of programming:
I have a main form with a button and a textbox. The button opens another form with a datagridview. What I want to do is pass the selected value from the DGV back to the textbox on the first form.[code]...
I have a Form1, the user types a "Client ID" in a textbox if it's not a valid one, it opens a Form2 in which the user selects the correct "Client ID", once selected he presses an OK button. And there comes the porblem.. it opens a new Form1 with the Client ID that he selected from Form2, but I still have the first Form1 opened.
I have two Form1 opened...
I which to keep the original Form1, but with the value sent from Form2..
I'm using this code:
Code in Form1
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Say I have public string variable called "_Test" on Form1, how can I allow Form2 to edit/read the variable from that form? I tried putting this on Form2:

I need to share variables across two forms in vb.net. One of them is the main form and the other is a child form.
Create a static/shared variable in one of the forms and access it in the other forms via:
Form1 frm = new Form1(); //creating object of parent to access shared variable
frm.a = "abc"; // passing value
Send an instance of the main form to the child form when creating the child form. The variables can then be accessed via a property function. Create global variables in a module. This seems like the easiest option, but I doubt it is the best option.I also read something about delegates and events, but I don't know how to implement this.
