Adding A Module To Project - Variables Never Get Set To The Values In The Text Boxes?
May 4, 2011
Form1 has 2 public string variables defined and initialized to "" (an empty string).Form2 has 2 text boxes and a button. When the button is clicked the public variables on Form1 get set to the values in the text boxes.This works fine.I recently had to add a module to my project so that I could use Main as the startup item. Ever since doing that the above no longer works.The variables never get set to the values in the text boxes. They just stay empty.My Main code is simply this for now:
i have a problem that wants to display a random series of coin tosses(coins flipped per each user click)i can't get the picture box to display the coins
Public Class CoinToss Dim randomObject As New Random() 'creates random object 'display results of coin toss
[code].....
it should count the number of time the "toss" button is pressed and display that number as welli also need to add a flip module that doesn't take arguments and displays false for tails and true for heads, but i'm stuck
If I'm trying to output to a listbox, what is the easiest way I can enter a string and then a variable on the same line? I'm trying to use listbox1.Items.Add(...). Obviously outputting a string is no problem and outputting a variable is no problem, but I want to add a string and then a variable after the string. For instance:
name = "Joe Smith" listbox1.Items.Add("Name: ", name) [or something like this] [Output] Name: Joe Smith
I am having a bit of a problem working with textboxes, subroutines, and modules.I have a form (frmMain) with 30+ textboxes. These textboxes collect data input by the user either manually or the user can choose to have the program randomize all the numbers in the textboxes by clicking a button. To randomize these numbers, I have a subroutine in the module called randomizeData(). The problem I am having is that the textboxes on frmMain are never actually updating themselves with the random numbers generated in the module. No errors or anything, but no results either. Here is a simple summary of what I have going on.
Public Class frmMain Private Sub cbRandom_click() randomizeData() End Sub
I have 4 checkboxes available, what I want is the user to be able to select as many of the four checkboxes.Each of the four checkboxes have a value, but when i set the code it only selects the first checkbox and only adds the first checkbox i select to the totals, rather then all selected checkboxes.The values have been set in the module and all the values appear correctly, they are just not adding all together when i select more than one checkboxHere is what I have in the calculate button.
Dim PriceDecimal, DiscountDecimal As Decimal 'Find Price of Service If MakeoverCheck
i had a look at how to set values of variables from nummbers stored in external txt files the variables then needed to be added up so i used trial and error first
((XVAL) + (NEWVAL))
assuming that XVAL was set to 10 and NEWVAL was set to 20 i expected to get the answer of thirty but waqs presented with the new value of 10 20 VB.net pysicaly added the two values together but i wanted the mathematical product of the two which is ((10) + (20)) = 30
I want to make program which will display specified website. but i want to make login form which will takes variables from that form and put them into boxes on that website and will automatically log on user.
I was wondering if it is possible to point to a textbox created in the form designer via a string variable. Basically, I'm creating a golf management system with a feature allowing a user to define their own course. Each hole has a corresponding textbox into which a user can input the hole's par and then the system should total up the first 9 pars, the last 9 pars and then all 18 pars; displayed in 3 different textboxes.
The input textboxes have been named txtP1, txtP2, ..., txtP18, so I was wondering if I could simply concatenate a loop control variable onto a constant of "txtP" to point to each input box.
This is what I have at the moment, but it's throwing up errors saying that .text is not a member of string.
Sub UpdatePar() Dim inpar, outpar, totalpar As Integer Dim pointer As String
I recently bought a barcode scanner for God knows what reason, just to play around and now it seems that its easy to sort out everything at house with it (e.g. Disc Collection). So I decided that I need a special program for it to get sorted with the collection. I am new to Visual Basic, but used to do programs with Java 6 years ago, but it doesn't seem to be any similar to each other. Basically I have a Microsoft Visual Basic 2008 and here is what I want to do:I have Form1 which contains of a textbox and a button (which will be Enter further), a textbox for total amount spent (which has to be calculated from Form2 and a nice background. I also have a Form2 in the same project, which contains 3 textboxes (Title, Price and the barcode numbers)So my problems are: As I said there are just 3 textboxes in Form2. Is it possible to copy Form2 three times on Form1 with different variables in text boxes? For example Form2 1st copy will have one Title in textbox, Form2 2nd copy will have another Title in textbox and etc. The Titles are in excel (.xls) file.That is a problem further, but my problem for now is how to make barcode scanner working. The barcode scanner basically reads barcode and inputs numbers in a textfield and automatically presses enter.As I am new, I do not know how to make this work. When I launch the program the textbox has to be selected rightaway, so that I do not have to use mouse. As it is selected I read the barcode and the numbers are in the textbox right away and Enter key is pressed (but I did not assign OK button with a Enter key and I cannot output anything now). So how do I assign the button with Enter key and the textbox? Now as the button is pressed (OR ENTER KEY is pressed) The text in the textbox has to be selected again (so that I can input a new barcode) and Form2 has to be called on a certain place of the screen (e.g. 200x100px is the starting location).
Now when the Form2 was called it read the data from Excel spreadsheet and now the textfield in Form1 is ready to input new barcode. As new barcode was read the same situation is happening, but now the Form2 is copied into a new place with new parameters (e.g. 300x100px is the starting point).Same for the third time, but on 400x100px.For the fourth time the Form2 is not copied again. However the parameters of the third copy are getting the new data. Parameters of the third one are going to the second copy, second copy to the first one and the first one is stored in a text file or somewhere else to use further. (I wanted to use up and down buttons to search for what I have scanned)
am having a big problem trying to make a program that will add multiple text boxes together.What I need to do is add all the text boxes together. If it is less then three leave it alone, if it is more then three then put a 10% discount on it. There are also other charges but the main thing I'm struggling with is adding the text boxes.
Here is some of my code: Private Sub TotalButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TotalButton.Click
I am building a very basic calculator which adds and subtracts various numbers from various text boxes when I click on the 'button'. This works fine with:
etc but when it comes to adding or subtracting time I get completely lost.Say I want to add 50 minutes in one text box to 12 minutes in another to display 1:02 in a third text box by clicking the same 'button'I am using Visual Basic (in visual studio 2005) to program a Windows Mobile Classic 6 PDA?
Basically im trying to add 4 new picture boxes everytime a specific text changes. This is a picture developer based off the binary of a number 1 - 10 I can get 4 to change everytime the text changes but i have no idea how to add 4 everytime the text changes. here is the coding i have so far.
Imports System.Drawing Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
I'm writing a database program that will take various information from the user via text boxes, then save them as a *.txt file. I've already figured out the majority of that business. However, I'm having trouble programming a ListBox.
The ListBox needs to accept three pieces of information from 3 Text Boxes, then concantenate them when a button labeled 'Add' is pressed and scoot them to the ListBox (lstshowresults) while clearing the three boxes at the same time.
Im extremely new to programming. Im trying to determine how to get values from 6 different text boxes put them into an Array. They are in a function not on the form. Three of those values need to be used for calculation.
Im attempting to loop through all the text boxes inside of a group box, and add the text into a list box to later be written to a text file. Here is the code I am using.
Dim cControl As Control Dim FILE_NAME As String = "Tester.efw" Dim Group As GroupBox
[code]....
Now instead of locating only the text boxes, apparently it is still trying to identify the labels as text boxes, because I am getting this error:Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.GroupBox'.
i'm new at vb.net (though i have extensive vb6 experience and oracle experience), and i need a sample program/project which uses multiple queries (of the same oracle database namespace) to display counts in text boxes.user will use a pull down list to select action from there.
Anyone know right off hand a cleaver way to chop up a Text value from a table... Scenerio is this I have one table with a name (Smith, Timmy Alan) in a table text(30) format. I can pull the value to a string in VB but I want to only take the last name for one string and the first for an other string.
I used this code to created 2 combo boxes General and Specific...and Only show Specific (Combo when Combo A is chosen.....What i need now is to know how to assign specific values to the items in combo b (Specific).??? If i chose a sode, Fanta, i want the total price to be $10.00 (this price will show up in the finial price box..
I am developing a program that makes it easier for users to log on to a website and search for specific data. I have the first portion finished in which I have a form with the Ax Web Browser control.
The web browser control navigates to a local website and automatically logs in for the end user. This is done by using code which automatically fills in the username and password and then submits the form to logon using something similar to this: WebBrowser1.Document.Forms.Item(, 0).elements("txtUsername").value = "user"
Once logged on - there is a search page which contains a combo box and list box. I am trying to set specific values for the combo box and list boxes.For example - the combo box on the website is titled: cbxDate and contains the following values: Today, Yesterday, This Week, This Month.
A list box titled: lstArea contains the following values: Zone A, Zone B, Zone C, All.I am trying to figure out if there is a way through code to select, in this example, "Yesterday" in the cbxDate and "Zone B" in the lstArea on the webpage.If anyone knows of a solution, please feel free to let me know. Be advised that I am using the Ax Web Browser Control.
I have developed a VB.NET application that generates code in a specific format. It has a multitude of features and everything works great. I recently added the ability to save generated code to a text file as well as the ability to load those text files into the application. I am looking to add one last feature (perk). I want to include a bunch of pre-coded text files with the application, that new users can load and use immediately. As of right now I have the application creating the directory they will go in, but can't find anything on how to include the text files and have them placed in that directory. This application uses one-click deployment (in case that matters).
i am writing a golf score program and i have 18 text boxes. i also have a text box that will calculate the total of all of the 18 other text boxes. what would be the best way to add these text boxes? i have already written code to only except numbers 1 thru 8 for each text box.i started with some code like this:
but if there is no value in one of the text boxes i get an error:Conversion from string "" to type 'Integer' is not valid.so i am guessing i need to check for empty strings and then ignore them
I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?
