I need to compare the data between two text boxes and a variable. If the value of the boxes don't match up and the variable is -1, I need to fail it.When I do this:
VB.NET
If Not Me.txtPcidSystem.Text = Me.txtPcidDatabase.Text Then
I have no troubles, but adding the variable check produces a false positive.
VB.NET
If Not Me.txtPcidSystem.Text = Me.txtPcidDatabase.Text And TestData.BypassCheck_PCID = -1 Then
The way the code is laid out, I have to do this in one line. I can't check the first condition on one line and the second on another.I've tried separating the data out with parantheses, but it's producing the same results.

I dragged and dropped a label from the toolbox onto a form (Label6) and stupidly went to the properties window and set "Text" to blank. Label6 shows when the program is run using F5 but does not show on the design surface if I want to move or remove it. How do I get it back onto the design surface or remove it completely?

I'm trying to make a small database out of text boxes and text files, something where sql would be overkill, not to mention beyond my experience. I want to be able to write the contents of the text boxes to a file.txt (the easy part) then being able to retrieve them back out into individual text boxes. How would I pull this one off?

I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:
Dim picLight(2) As
Boolean
For intX

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?

I don't have an example code, but recently figured out how to make a single sub handle the keydown event for multiple text boxes.What I would like to know is if it is simple enough to have the object name that is sending the event instead of "microsoft..text: 54654" (sender.ToString in a debug window) type of return. I don't know how to make use of that.

I am thinking is to have a question, then between 2-4 answers, and depending on the answer a point value gets assigned to a variable, but then when that one question is answered you can click a button that moves to a next page type of thing with a new question on it. I think I could probably figure most of this out but when it comes to switching to a different question I am not sure how I would do that.

I have a mesurement that could be any random value, just for fun well make that 2440mm i need to divde that by the industry standard of 610mm which comes out at 2440 / 610 = 4
Programicaly written NEWVAL = YVAL / STDVAL
NEWVAL (4) gives me refrence to how many instances I want to append a new line in a txt file I know that I want the first line to say 0,0,0 and the second line to say 0,610,0 the third 0,1220,0 the fourth 0,1830,0 and the last 0,2440,0, though this is easily achived with addition how can I automate vb.net to produce a new write line for each each instace of 610 if the YVAL is user defind.Put in simple terms half would be missing if the YVAL variable is double in length at 4880mm?

So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.

I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

I want to alter the .visible property of a label based on if a variable is positive or negative (Hiding it for negative values)
But I want to do this for lots of labels so If Statements are too bulky.
I tried this:
Label1.visible = CBool(IntVariable1)
But it turns out CBool returns True for ANY value and False for Zero.I'd assumed it would be True for positive values and False for negatives.How can I do it without if statements?I considered Modulo or SquareRoots to somehow convert a negative number into zero, but didn't want to complicate things with imaginary numbers.
