What is the best way to run an if statement if I have text in my textboxes?I have 6 textboxes,textbox1 will always have text but how would I do this?[code]
View 12 RepliesI so far have created a randomizer in Virtual Basic 2010 that:Takes people's names that the user imputed in form2 into an array (split by spaces).Randomizes the array Displays the array with a consecutive number and period behind it for each name that was imputed.
Here is the source code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim names() As String
Dim i As Integer
[code]....
Pay attention to the last bit. I want to take the variable txt and split it. Then I want to take the first 10 names and display them in RichTextBox1, take the next 10 names and display them in RichTextBox2, and display the last 10 names in RichTextBox3.
I have a form with 2 TextBoxes that I want to be able to save to a text document like C:Data.txt. When I save to the text document I want it to continuously save. For example it when you open the text file it should look something like this:
TextBox1
TextBox2
------------
TextBox1
TextBox2
Is it possible to do something like that? A separator is not necessary, would be nice to distinguish different saves.
I'm running some if statement but I have hit a brick wall with what I'm doing and trying to do. If textbox1 has a value then I run different coding to if textbox1 and textbox2 have a value - Textbox1 will always have a value. [Code] What I'm trying to do is add an additional statement if both Textbox1 and Textbox2 have text, then to run code 1 if the last four characters in textbox2 ends in .jpg else to run code 2. [Code]
View 3 RepliesI'm trying to create a "quiz" program in VB. The questions to be asked are placed inside text files and have the following format:
[code]...
> VB thinks that im trying to open a file named, what im trying to do is open a txt file which have a file name similar to the value of integer.
labelQuestion.text = variable.Readline().
Im trying to come up with a do while statement that reads through a text file till the end while pulling out 3 different matched items, then writing those matched items to ascending spots in an excel file, and then creating a bar graph according to the saved data. Sounds complicated but...I have the program reading the text file, pulling out the first iteration of all three, writing them to an excel file, and I have it even graphing them the way I want it to. The only thing I havent done before (and which is probably the easiest), is creating the do while statement so it keeps searching line to line for the three interactions of what im looking for and writing them to ascending spots in the excel file.
Right now my code works like this, which is perfect for pulling out the first 3 and creating a graph, I just inserting a do while and a rowindex + 1 variable.
vb Dim alines() = System.IO.File.ReadAllLines("C:deviceinfo.txt")
Dim amatch As String
Dim muvalue As String
[CODE]................
I have a feeling in order to pull this off, I do not want to use the, "ReadAllLines" option and possibly want to put the text into an array.
And do something like: if lines.count > 0
But im not familiar with how arrays work in VB, and more specifically what the syntax is. The other tricky thing I am trying to add is an if statement that adds to a variable (such as i) everytime a line is added to excel so the program will write to ascending lines. I was trying to have the it work with the do while statement but pretty soon realized that if I did: i = i +1. Everytime it went through the loop then the data was going to be on random lines corresponding to their place in the text.
I'm having a problem with loading two text boxes from a saved text file. I've built a log in form that saves the user-name and password on separate lines in a text file.I have a save button and a load button. My problem is that I'm new to Visual Basics and I can't figure out how to get the two lines from the file to load into their separate boxes on the form.The code that I have loads both lines from the text file into the User Name Box.Oh the username is on the first line in the text file, and the password is on the second line of the text file. Could someone please help! My Loading code is:
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click
If File.Exists("Login Config.txt") Then
Dim ioFile As New StreamReader("Login Config.txt")
Dim ioLine As String ' Going to hold one line at a time

I have a line of code that is working in one statement but not the second statement. I'm not sure what I'm doing wrong, I am learning slowly but surely, and it is by no small margin because of the ave found here =) The error is occuring in the intResult = intSelection x intCount line of the SECOND Do While Loop.
The blue squiggle line is under "intCount" just FYI

View 3 RepliesSyntax error (missing operator) in query expression '''system time'''.this is the error that appears
this is my code:
Dim sqlCmd As String
Dim x As Date
x = Format(Now(), "General Date")
[code].....
the fields in the tables are all text fields.is there any way to fix this error? perhaps it is in my query but i really cant find a solution.is there an alternative to get what i want my program to do?it is basically entering an ID number and finding the record with the same idnumber and putting the system time on the timein field for that record.
I have a form that contains an array of textboxes that are created at runtime. 72 to be exact. They will be used to hold the serial numbers of parts that will be be read with a scanner. I need to check that there are no duplicates in the serial numbers while the operator is scanning in the parts and then change the backcolor of the matching textboxes if the text is the same in 2 or more.
I tried this and it doesn't work
Code:
Dim j, k As Integer
Try
For j = 0 To 71

I have this program I'm working on, and I was wondering if it was possible to disable/enable TextBoxes when specific words are wrtten. I tried doing this, but it errored. I'm a new programmer to VB, I just started a month ago, and I'm doing this for fun.
If TextBox1.Text = "Shutdown" then TextBox2.Enabled = True
I also want it so that you don't have to press a button to identify if it is the right text, so it could "scan" automatically.

View 1 RepliesIn my form, A user can do some stuff on my program which will create a new tabpage with a text box on it. The user also selects the name of the tab, which is then the name of the textbox with a "2" on the end of it.
What I need to know is how to get the texts from however many tabpage's textboxes there are and combine them into one textbox, as a sort of receipt.
What I was thinking, because I have this method of removing all the tabpages, is using a code like the one below maybe to do the job, not sure how I would alter it to work though. [code]...
