I have a number of images that I want to select a random number of and populate that number of picture boxes either dynamically or that already exist but can't think of the logic that would do it.
I considered dynamically creating them but don't know of a way to name them uniquely. I tried using pcbx& a variable but it didn't like that. Placing the image inside picture boxes that already exist, I couldn't think of a way to differentiate between them without what seemed excessive repetitive coding.
i am making a game in visual basic and when the picture box that you have to shoot resets, sometimes it resets off the form i use this code to make the picture box move randomly.[code]
My problem is after I created 5 rows of text boxes, I want to add random numbers to all of the text boxes in one time when I click the button.Here are my coding to create text box dynamically:
Private Sub btnAdd5Row_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddFiveRow.Click For Me.count = count To 5
I have some operations of Picture Boxes etc being performed. After the user finishes with the formatting, I want to give the user an option to print the work.But its the work is not done on the Rich Text Box but on picture boxes. I am not even sure, how many of the picture boxes would be there after the user finishes the job, since I have provided option for dynamically creating picture boxes as well.
Still working on a very simplistic poker game and I'm struggling with getting the code to show my cards in picture boxes. I currently have 12 picture boxes set up on my form and when clicking the "deal" button I created on the form, I would like a random number to be generated from 1-53 and based on the number returned I would like a picture of a playing card entered into the picturebox. I would like this to happen in 10 picture boxes. So playing cards will be shown in the picture box on 10 of them and a the card back on the picture box 11 and 12. After hitting a second button, I would like the 11th and 12th boxes to display a card from the deck.
With all that being said my questions are:
1. How do I associate the random numbers with my playing cards? (I have my card pictures in a file on my computer.)
2. How do I get the picture of the cards into the picture boxes? What would the code look like?
3. I have a button to clear all the cards, but how to I program it.
i Have this code which populates a number of combo boxes from an excel document, the problem is that it only populates the 1st three lines, does anyone know why this is??
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.
Im trying to make a program that allows the user to view additional information via moving the cursor over the label to view (make visble) additional information, in the form of text boxes and/or picture boxes. How will i go about doing this?
I have VS 2008 and use VB, not C#/C++ or whatever else. I'm trying to make a battleship game, and I've decided to use the only method I can think of to control the grid. A 2D boolean array for position marking. I have the array set up, and the grid set up in the design form, but I can't figure out with all my research how to link them together. I'm writing this program to shake off the rust before school starts again, and for fun. I took VB in school last year, a half year class, so I have a foundation, now I'm self-educating myself above and beyond the class. I've searched for a way to use a picture box array to use the coordinates of the ship to .Visible=True the picture boxes. I've been working on this for 2 days straight with no results. I just need a little nudge in the right direction. The exception I've been getting with my latest concoction of code is NullReferenceException was Unhandled. I think its referring to the fact that I have no idea how to link the picture boxes into the array. Here's my code, and I'll comment where the exception is thrown:
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click 'label for GoTo statements is Tryline:
I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
I am trying to make a texas hold em game and it is of the utmost importance that my code generate a random number. But using a random number function that I always end up with a lot of the same numbers over and over again. Any ideas on how to make it "TRULY" random? [code]
I've made an image viewer which opens a random image from a specified folder, but the random number is not that random at all... I've already used Randomize(), but without result.
I am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible
I am attempting to create a game in Visual Studio 2008 that allows a user 10 attempts to guess a random number between 1 and 50. I have a label box in which I would like to display the remaining guesses as they decrement. The code so far appears below.
My two (I am sure very basic) questions are:
1. How would I pass the random integer generated through the Generate Integer function to the AmIRight button's click function? I was trying to decrement the counter each time the "Am I Right " button is pressed.
2. I would also like to evaluate each "guess" when the "Am I right button is pressed. Is it possible to nest a Select Case statement in a For Next Loop?
vb.net Option Explicit OnOption Strict OnOption Infer Off Public Class frmMain Private Sub btnExit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExit.Click Me.Close() End Sub Private Sub txtGuess_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles
i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?
I am trying to create a lotto simulation, but don't know how to continue.I am using numericupdowns to allow users to select 6 lotto numbers. and labels to display what they have chosen, but i'm not sure how to prevent duplicates without creating a large number of If statementsMy question is, is there an easier way to prevent duplicates without writing a bunch of if statements?here is my code:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Lotto1, Lotto2, Lotto3, Lotto4, Lotto5, Lotto6 As Single Lotto1 = Val(NumericUpDown1.Text) lblLotto1.Text = Lotto1 Lotto2 = Val(NumericUpDown2.Text) lblLotto2.Text = Lotto2 Lotto3 = Val(NumericUpDown3.Text)
[code]....
I don't understand how to save the user selected numbers, let the computer generate 6 random numbers, and match the two sets of numbers together to see how many matches there are. As far as I understand the numbers should be stored in 2 separate arrays and then matched together to find any matches.
I am retrieving a single row (using a method) from a table, I want to populate each column from this row into text boxes. How can this be done in VB.net.
I have this program generating a firstname and lastname from a file. When I run this program I enter information in three textboxes. The first two are the salary low and high(salary1.text, salary2.text) and the last one is the number of "copies"(copies.text) that I want.. When I put a number such as 10 in the text box it outputs some of the same names. The firstname file has around 100 records and the lastname file has about 1000 records Why is it generating the same name The problem is even worse if I do something like 1000 copies.. it outputs the same thing 8 times and then does something different another 8 times
Public Class Form1 Dim sex As String Function randomfirstname() Dim infile As IO.StreamReader
i want to set a default number and you type in a textbox a random number it should tell you whether it's high or low ,and when you typed in the right nmber it a lable should says something like you win .And also how can you change PART of a lable by typing in a text in a DIFFERENT FORM
I have an Access Database that contains two tables. I would like to populate 10 text boxes on my form with the data from the tables. For example: Table1 has a list of names 1 thru 5 and I would like to have 5 text boxes on my form when the form is loaded to populate those names. I know how to populate a combo box with the information, but not sure how to do it into individual text box
Current Code: 'create connection and command string Dim conStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data
i have a combo box that on form load is populated but i need to know when i click an item, i will be able to code how to populate other combo and text boxes with data about the same person.
I am receiving information via a serial port as Integers. The information is the displayed on textboxes(two text boxes). My problem is that, I am failing to transfer this information to a Datagridview.I have written the following code.
Private Sub BtnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSave.Click TxtDuration.Clear()
with the code below thatprompts the user to select a row from the ListView1 control. The row selected is then used to update the Xml file with the text box content.The original code works well but I'd like to find out if there's a way to automatically select the ListView1 row based on matching what is in Cbox1 and
The first problem I am having is that it populates every cell with the same random number. How do I get it to create a new random number? The second problem is that I need to make sure each entry in the array is unique.
I want to display (DataGridView's) selected row contents (each cell value on appropriate text box) on text boxes on the form. This should be fairly simple task for experienced i am sure.So far i haven't been able to find a single working solution to accomplish that as most of the articles are written for VB / VB 2005/ VB 2008 and not VB 2010.
Here is what i have already tried. (I tried putting an image but i can't due to my privileges over flow) TextBox1.Text =DoctorsDataGridView.CurrentRow.Cells(0).Value.ToString It strangely works for first 4 selected rows and populate text boxes but fails for the rest of the DataGridView.
My screen tends to seize for a few seconds while the list boxes are populated.I moved the call to the List Populate procedure to the form's shown event.This improved the performance slightly but not enough.Is there a method whereby I can ensure the form is fully loaded and displayed before the lists are populated?
VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much. When generating a salt, should the LENGTH of the salt be random, fixed or a random number within a (min/max) range? I am using RNGCryptoServiceProvider to generate the salt, just unsure of the length of the salt.
I heard that you have to add some code to a random number generator
results(1) = Int((5 - 1 + 1) * Rnd() + 1)
so that if it is used again and again it keeps generating new numbers as apposed to what this piece of code does by itself which is creates the same number every time.what is the code?
