No Values Show Up In Labels When The Program Is Ran?
Nov 17, 2009
I have designed a program that, when the "caclulate" button (btnCalc) is pressed, it asks the user for a file name, then pulls data from that file (file is a .txt of 100 decimals, one per line) and displays the Total, Average, Highest and Lowest. To do this, I have placed all the data into an array, and then used the array to get the information I need. All the code is in place, the only issue is that when the "calculate" button is pressed and the file name is entered, nothing happens.Need to figure out why the values are not displaying in my 4 labels (lblTotal, lblAverage, lblHighest, lblLowest)!!Here is the code:
Imports
System.IO
Public
[code]....
(For the record, I know I could get the data in one pass, however, being a beginner, I like seeing each value computed separately.)

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?

Well im currently developing an application for public use, I have a login screen in which the user enter's their registered credential's and the progressbar loads by increments of 3, now i placed 6 labels ontop of eachother and where the progressbar coding is i put:
If Progressbar.Value >= 1 Then
Label3.Show()
If Progressbar.Value >= 20 Then
Label3.Hide()
Label4.show()
And so on up until Label8 Show at 100%,
Now the problem is... As i have placed the labels ontop of eachother i need them hidden until they are called to show, i have tried adding a background worker to do this but have had no luck, all i see is the labels overlapping eachother when i run my application when i want them hidden untill Label3.Show() is called, and then to display them as they are called and hide them when another one is called to show...

lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?

My project will end up with several forms to be filled out. Once a form is completed, a button can be pressed revealing the next form or previous form if something is going to be changed. I've been using Me.Hide() so that the users screen doesn't get to cramped.
I'd like a few things to happen. If an input from one form changes a value on another I'd like it to update automatically, I figure some event on button_click or form_load. My problem is that different things work depending on how I open or hide a form. I would also like the forms that have been Me.Hide() to retain the value in the textboxes. Let me show you from a practice vb project so that you don't have to dig through the larger code.
Public Class Form1
Public Shared Info1, Xcord, Ycord As Double
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code]....
1) If I don't use "Public Shared", TextBox1.Text does not update.
2) If I reopen Form1 with the "Dim First As New Form1" method it seems to refresh the Form1_Load. If I use My.Forms.Form1.Show() it does not. Another side effect is that clicking the close button on the ControlBox ends debugging when using "Dim First As New Form1" and does not when using My.Forms.Form1.Show(). Wierd. I've set ControlBox to False on Form2 and Form3, otherwise the program remains running in the task manager. I've read other solutions to that problem, but my solution seems to work for me so far.
3) Xcord and Ycord are my attempts to have the other forms open on top of the first form. My problem now is that I have them set to CenterParent and they open where the first form used to be. If I move Form1, Form2 and 3 open where I've left them instead of centered on Form1, maybe. Form1 is set to WindowsDefaultLocation. My new plan is to set to manual and have Xcord and Ycord update and then offset based on form size. So far I haven't implemented that code.
4) Me.Close() ends the program.
Public Class Form2
Public Info2 As Double
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim First As New Form1 'Done so that Form1.Info1 works
[code]....
I'd like a consistent method that represents good programming practice. My understanding is that Public Shared is frowned upon. I'm also wandering if Me.Hide() is the right choice. I've also played around with .ShowDialog() which didn't work?

I have to design a project for my IT course at college using Visual Basic. The task is to create a program which allows the user to enter the height of a room plus the width of the walls as well as the paint which costs different prices. I have managed to get the program to work out the cost of painting each wall, but I cannot get another label to show the price for painting a full room, when the result is basically adding up the cost of painting all of the walls. how to add up multiple values displayed in labels?

If rad1.Checked = True Then
If t1.Text = rad1.Text Then
MessageBox.Show("Congratulations")
ElseIf t2.Text = rad1.Text Then
MessageBox.Show("Congratulations")
ElseIf t3.Text = rad1.Text Then
[Code]...
so i have this code which is trying to allow the user click the label (of which there are 26) and then decide whether the letter in the label matches the letter that has been generated in the radio button. I KNOW there is a more simplified to do this and much less code to write but i cant work it out. this is an image of what im trying to achieve but instead of buttons change those to radio buttons x 3.

I want to get a matricial data (a matrix of numbers, like a txt data with TAB separators) from the clipboard and put these numbers each one in many Labels (or other Control that would be easier to work with numbers - maybe NumericUpDown, but I don't like his look). I don't know how to Declare, Define, or anything.... I just want to click on a button and then get the data from the clipboard, check if it's a number (or matrix, or whatever).... and put one by one in each Control (label) that I want.For example:
I have in the notepad the follow:
1 "TAB" 2 "TAB" 3 "TAB" 4 "ENTER" 5 "TAB" 6 "TAB" 7 "TAB" 8 .. end
like a matrix {1,2,3,4 ; 5,6,7,8}
If I just copy it to clipboard, it will be copied like a matrix, right?? So, what is the command that I have to use in VB that catch this data and bring to my program (clipboard.getdata would be the more correct?)And then, when I alredy have catch this data, how can I put the number 1 in the label1, number 2 in the label2, number 3 in the label3 and so on..Remember that I interested in use this numbers to calculate other values after and present the results in other place, and I know (maybe wrong) that labels is not the more apropriate Control to work with numbers?

shove in the right direction on this:My program is setup to instantiate/build five labels at run times, corresponding with those labels five texts boxes are built at run time. The user inputs four numbers into the first four text boxes and then when you click the total button, it totals the four boxes and outputs to the last text box

Looking for a bit of help with some code im working on. I want to randomly input a text line from a .txt to different labels in my program. So far i have this:
Dim FILE_NAME As String = "question.txt"If System.IO.File.Exists(FILE_NAME) = True Then Dim objReader As New System.IO.StreamReader(FILE_NAME)
[Code]...
This works perfectly, but as you can see there is no randomization, it just runs through each line. I want one out of every three lines to be chosen. My text file, on each line, has question tab answer tab answer tab answer tab answer tab correct answer. So for the first inputted question i want it to chose one of the first three lines, second question chose a line between line 4,5 and 6. etc.

While trying to make a prog to print on individual sticky labels I came up with this:-
Code:Imports SystemImports System.Windows.FormsImports System.DrawingImports System.Drawing.Printing
Public Class frmLargeLabels Inherits Form Private WithEvents printDocument1 As New PrintDocument Dim memoryImage As Bitmap
[CODE]...
I pinched it from a Print Form routine but changed the coding in the Private Sub Capture Screen event. ie: RichTextBox instead of Form. (Dim s As Size..........) memoryGraphics has to be twigged to location on form. And, of course location and size to print in the Rectangle.All things to do with a RichTextBox - such as Font, Color, etc can be used making a super-duper label. :8-0::eek: I have not seen anything to do with RTBs giving this.

I am writing a program that will display numerous labels in English and Spanish. The problem is I have the formatting correct and labels aligned for English, but when I hit the button for Spanish the labels on the left overlap the labels on the right. I did set the text on the Spanish side to include 10 spaces before the text, which does align it properly, however there has to be a better way to do it. I tried padding the label on the form which works good, but I would like the padding to only take effect when the selected language is Spanish. Once English is selected I would like the formattting to go back to normal.

I have a P/L chart which has a left scale (Y axis) which starts from a negative value. I want to format the axis labels (the major tick mark labels) so that the negative ones are red.
Something like;
If cht.ChartAreas(chtarea).AxisX.MajorTickMark.Value < 0 Then
cht.ChartAreas(chtarea).AxisY.LabelStyle.Font = New Font("Verdana", 9.0F, FontStyle.Bold, Color.Red)
[Code]....
Of course that doesn't work since MajorTickMark doesn't have a value property. How does one make this work?

With VB, but I've got the few basics down, file naming, adding objects, naming objetcs, etc. But the reason I'm on here is because I cannot complete even the first step. Our form is 640 X 480, and we need to have two labels, both have vertical scrolls. I know how to add and resize the labels to meet my needs, but I do not know how to create scrolling labels. Or are they text boxes? On our bubble chart (Do you know what that means?) it says lblInformation. We are going to have clickable radio buttons which will update the lblInformation with info about each of the radio buttons.

If it is at all possible, I would like to print a page that is layed out with labels filled with text from previousley stored information from the program. now, obviousley, because the text can change in amount, and so the labels need to be able to change in size, and if at all possible allow multiple lines, though if there is no way to do it, then an unchagable text box would serfice.
There is a problem though, the fact that the labels will be changing size means that the position of the labels needs to be variable to the previouse. Example: the box above needs to be bigger, so the box bellow needs to drop down equall to the amount that the above grows.

I'm trying to make a program that allows the user to click on labels which have a number in it and then that value has to be stored into a different label.
For example the user click on label1 and the values goes into label12, then it click on label3 and the values goes to label13 and so on.
At the moment I can only code on the respective label underneath (1->12,2->13...) but it has to be in any order (5->12,7->13...)
Here a picture and below my code:
