Changing Labels From Class?
Jan 13, 2012
I am trying to make a class which will take receive a form and then change the labels on said form.
this is the class
Public Class ScanClass
Public Shared Sub UpdateScanHistory(ByVal frm1 As Form)
frm1.lblLastScan5.Text = frm1.lblLastScan4.Text
frm1.lblLastScan4.Text = frm1.lblLastScan3.Text
[Code]...
this does not work as i would expect tho. I was hoping that if several forms had the same label names, then I can just update them all through the class by just passing the form. is there anyway to achieve what I'm trying to do.

I have a label showing Employee ID, First Name and Last.I was wondering how can I change the Employee ID to a forecolor maroon.
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I'm making a project that judges contestants. I have 3 labels at the bottom of my form that will keep a running total of the top 3 contestants, and change as the contestants score higher or lower. I'm not sure if I should use a loop or if statement, or where to begin at all.[code]

I currently have
Private Sub LabelClick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label14.Click, Label15.Click, Label16.Click, Label17.Click
If sender.backcolor = Color.LightGray Then
[Code].....
But there are ALOT of labels (about more than 300) and typing them out (or selecting them in the menu) consumes alot of time. Is there anyway to put the rest of them? I have about 8 groupboxes with these labels that need to be changed (there is another one that doesnt need this) so they are labels inside of groupboxes.

I wanted to make a flow chart with more than 50 labels (see this link for just a small portion of the flow chart [URL]). I looked all around but couldn't find one in VB 2008 with the same problem. but anyway, my questions are:
1. Is there a way to set the color of all the labels instead of just one by one say:
Label1.BackColor = Color.FromKnownColor(KnownColor.Control)
Label2.BackColor = Color.FromKnownColor(KnownColor.Control)
Label3.BackColor = Color.FromKnownColor(KnownColor.Control)
...
...
...
There should be a way to loop through them
2. Is there a way for search through the Labels and find for example Label14? or a label with tagindex of 14? I rather be able to find label 14 but the tag also works.
3. Is there a better way to represent flow charts and stuffs like that in VB 2008?

As a brief summary, I have an issue writing a program. A part of the program has a While loop that is supposed to change some labels to random numbers every iteration of the loop. But, instead of all that, the labels just turn blank until the end of the loop is achieved, and only then is the random number written.
While (o < 3000)
r1 = Rnd()
str1 = CStr(r1)
Label1.Text = str1
o = o + 1
End While

I am creating a dice game that you try and obtain a straight with.This is my equation for the random roll.
Private Function CreateRnd() As Integer
Randomize()
CreateRnd = CInt(Int(Rnd(1) * 6) + 1)
End Function
This is what I am trying to do
Private Sub RollBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RollBtn.Click
'checkboxes
Dice1.Enabled = True
Dice2.Enabled = True

I have made a program wherein you the labels are dynamically created with a press of a button. if you press on the label, the label would then change color from white to blue. my problem is that how will you make the backcolor of the label change when the button3 is pressed.
here are the codes. placed the whole thing since I dunno if you guys would understand what I mean.

PS here is the link to what my program looks like. link to my program . the button3 in the image is Reserve Seat.

am running VB express (2008 edition). I have a class that holds 2 arrays (1 array represents the digits of the integer side of a number the other holds the decimal digits) I have overloaded all the operators to work with these numbers as if they were one. Each operator has the following format:
[Code].....
whats happening is that the sign of the b variable (and only the b variable) randomly changes. Almost allways at the statement bb=b (bb is in place so when I reach that point I know what the variable had before the calculation). I can watch it change as I step through the code (stepping over the operators) I can watch it change almost allways at the bb=b, but sometimes in other odd places (such as the d=a*yparam statement). I can change the values back to their original and step through the code(stepping into the operator this time) and it will not do it. It NEVER does it when stepping into the operator, only when I dont, and only sometimes. I have spent the last two days working on debugging this one problem, with every other variable in the function it works like it should and I am not sure what to look at next. I know it does you no good without seeing the code but didnt think pasting 8,000 lines of code would go over too well so I would be willing to send the source to anyone

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...

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.

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:

I'm currently refactoring an old Visual Basic DLL (VB.Net), which stores all of its data in one module called Globaldefinitions as public fields. There are about 200 fields, referenced thousands of times all around the code:
Public Module Globaldefinitons
Public a As Short
...
Public zz10 As Double
[Code]...
I need to change the module into a class with non-shared fields. This means, each and every of these thousands of references needs to reference the instance of that class:
globalDefinitionsInstance.a = 5
How do I go about this efficiently?
Regular expressions operating on the source fall flat. Refactoring tools like Re-Sharper or CodeRush don't seem to offer this functionality. Visual Studio 2010 cannot do it automatically either.

I have put this code in the global form Inherits System.Windows.Forms.Form. And then in the form that will inherit this from the global Inherits MenuStrip. "MenuStrip" is what the global form is called. But keep getting this error: Error1Base class 'MenuStrip' specified for class 'Lesson2' cannot be different from the base class 'System.Windows.Forms.Form' of one of its other partial types.

The last word, "ClientProfile" has the scary squiggly red line below it. It is not recognizing my class.Even the Intellisense is not picking up te class. Do I have to register the class file in any way?

so I used to mess around with C#, just a little. And someone had helped me make a class for Visual C# that was supposed to do the math parts for "internal structure" - which the program used for a part of its calculations and screen... Basically there were 2 options. Endo-Steel and Standard. The user would use a updownbox to determine weight of the machine and then internal structure was a % of that total. If it was standard then it was 10% of the overall weight, if it was Endo-Steel then it was 50% of standard (so 5% of total weight) rounded to next 0.5 (so .25 was .5, 1.25 was 1.5, 1.75 was 2.0, etc). I have the code for the C# class file for it, but want to make it in VB.

I am trying to add labels to my form on the fly and I don't know how many there will be and this is my code:
label1 = New Label()
label1.Name = controlName
label1.Size = PreferredSize
FlowLayoutPanel1.Controls.Add(label1)
ListBox1.Items.Add(controlName)
The only thing that I get is the first label made and I shows nothing else.
