So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:
Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.
I have written a function that gets the alexa ranking of a given url, now this function works perfectly but I want to loop through a ListView of urls and grab the alexa rank of each item (url) with my function.The code works great if I put a MessageBox in the loop to test that the function is returning a value but when I remove the MessageBox the loop does not work.I need it to loop through adding each result without a MessageBox stop in each loop.
vb For Each Item In ListView1.Items Dim result As Integer result = GetAlexaRank(Item.Text)
I have this little application that runs a SQL query works great, now I want to have a Start Button run the and display results then System.Threading.Thread.Sleep(300 * 1000) for 5 min then run again and display results and loop till I buttonstop_click. unsure if the sleep is the best method.
I am new to VB programming. I have the following code. When I execute my program only the last value from the loop is displayed in the label. I do write my code so that all of the values (years 1 to 5) show up in the label?
seriously struggling with this one bit of a program im creating. Im trying to simulate a moving queue, using a number of pictureboxes (controlled by Timers). Once a picturebox vanishes, another appears in front of it to symbolise movement throughout the queue.Anway... Im struggling with LOOPS! I cant seem to make the funtions repeat and I need this urgent due to a deadline in 16 hours time Background Info: The form will run for 60 seconds, after which anotehr form will loads (MorrisonsQueueSummary).Here is the syntax so far:vb.net
Public Class morrisons Private Sub FormTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MainTimer.Tick
Is it possible to create a loop using a string I am writing a program and I need it to output 3 letters ahead of the letter you input for instance if you input a then it outputs d and if you input u it outputs x, and also the same with capital letters A then D U then X and so on. I have writted the program the only problem is that when I input X I want it to output A but it outputs [ instead I need to create a loop where when I input X it starts the alphabet over again, and I need to know if it possible and if so how will I go about doing so.
I have a button and text box. Every time I click on this button a number increments in the text box (textbox1). So far so good. Also on the form is another button called 'Submit' and three more textboxes. (textbox2, textbox3 and textbox4) What I want to do is every time I click on the submit button the value in textbox1 will be placed in the first textbox (testbox2) I will then increment the value in textbox1 and then hit submit again and the current value will be placed in textbox3 etc. The question I guess is how do I create a for - next loop that will increase the textbox?
I've got an app working semi-background stuff in the GUI thread. Another thread won't work and a timer won't work. But I want the app to be responsive while I'm going my 'background' work.I cound use application.doevents - but that gives me 3 bad choices:
-loop with no sleeps - end peg an entire CPU (my task waits on stuff besides calcs & I/O so this matters) -loop with a sleep - then the app slows down -Try to make a 'smart sleep' loop that speeds up when lots of messages happen (check for messages in messagefilter function)
[code]why I can't use application.run, or threads, what I want to do is handled the OnUnhandledException event, then leave my app open for a while while some winforms stuff closes it down gracefully and tells my watchdog program to restart the app. after allowing the user to finish a critical process, too. Yes, I know people thing that a program getting OnUnhandledException deserves to die (obviously MS), there are 'dangerous' things that could happen; none of them are as dangerous, however, as the wrath of my users. Looking for vb.net sourcecode exact translations of the above two functions.
threads that watch folders and process files. This works fine, but every time needs change to add a new folder or just change some existing rules I have to go in and change the program. I want to builda front end that storesprocessing infofor each watchfolder. The program would then read the configs and build the threads based on them. I cannot find a way to loop through creating the threads.
I want to be able to reveal and then populate a certain number of labels. The inefficient way would be to SELECT CASE on the number of labels required and then populate these in turn. I am looking for something like this:
For i = 1 to RequiredNumOfLabels Label & i.visible = true Label & i.text = DataTable.Rows(i).Item(2)[code]......
is the problem as after the line is executed, lbl still equals nothing.The reasoning behind it is that I was trying to create an invoice generator in vb.net and I was hoping that this would be a simple way to do it - count the amount of items in the order, populate the labels with the names of the items, reveal that many labels.
I am using Excel 2003 and I am wanting to create a simple macro in order to run a for loop and then have the information output the numbers to cells.
Sub ForTest(i As Integer, j As Integer) For x = i To j y = Rnd Next x End Sub
This is my code. Now how can I print my x values to the A column and print my y values to the b column so that they line up as a pair of coordinate points.
I'm trying to create an app with a backgroundworker to enable canceling a loop, but it won't work as I hoped it would.When I debug right after the line ThreadWorker.RunWorkerAsync() the programm goes directly to Private Sub ThreadWorker_RunWorkerCompleted and skips the Private Sub ThreadWorker_DoWork part, where of course the actual code is in (I've left that code out, it's about a 100 lines and without BGW it works).Does anyone have an idea what could be wrong with it?
I'm doing a small tool that basically wipes the document properties of each .*doc file in a specified folder. The code is working, however, if the document is already opened, I'm presented with a text box asking if I want to open a read only copy etc. I want the code to abort if that happens and rather write it down in a log file or something. And just move on to the next file. How can I do this? I'm talking about editing thousands of documents.
This is the code I have so far:
Imports Office = Microsoft.Office.Core Imports Word = Microsoft.Office.Interop.Word Imports System.IO
Whenever I try to create a new CD object I get a stack overflow. I want a parameter to be passed into mediaFactory so that it could be determined what type of media is created.

My script should Read order numbers and for each read loop create a text box and populate it with the value, then loop again and put the next text box below with the next line orderno.... (just to make it fun it has to dynamicaly create its own box for weach loop to sit in)however it only does 1 loop.

Is it because i should be skipping to the next row and not looping, if so how can i create a new textbox eachtime without a loop?
Are u able to take a look at this code and see how can I create a loop on timer1 to control the rate of timer 2... Coz this is the code that my lecturer had amended..
