Possible To Create Loop Using String?
Sep 14, 2009
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 string where I have created a template so to speak.
{
Dim myvariable as string
Richtextbox1.text = Richtextbox1.text & "The dog jumped over the" & myvariable & "to find the fox."
}
I have a list box that contains a list of options that loads into the variable example: fence, bucket, etc.
So the sentences would read like
The dog jumped over the fence to find the fox The dog jumped over the bucket to find the fox
Right now I have it coded to display into a rich text box but everything is in the same rich text box.
I'm trying to load the string into an array at the end of each loop this way I can then have each sentence separated.

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:

I have a somewhat unique problem that I have looked for an answer to and continually hit brick walls. The problem is this. I'm using vb.net to read a byte array from memory which total 32768 in length, which is converted to a string. The memory is the active console chunk in the game Call of Duty 4.

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

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?
See below.

Option Strict On

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'd like to create a loop that dupliates a label I've made and put it all over the screen. Example of what it would look like.
For i = 0 to 52
originalLabel.duplicate ("duplicatedLabel" & i)
next i
So later I could go through all of them...
For i = 0 to 52
//... some logic to determine color... then assign it somehow
duplicatedLabel & i.backColor = Color.red
next i
[code].....
I can do that in Flash/Actionscript but dunno how to do it in VB and I can't find it anywhere.

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

I have for-next loop that loops 6 times around before exiting. Each time it loops it adds a small number and a space to a string so I end up with a string containing 6 numbers separated by spaces. Whats ends up happening is I get "555 555 666 666 777 777" when I should get "444 555 666 777 888 999". I know for sure it isn't the code that generates or applies the numbers because when you put a messagebox.show at the end of the loop it works perfectly, so it seems to me something is happening to quickly but showing the message box every loop gives it time to catch up. What can I do here?
