I have a 'For Each...' loop in the VB.NET code for one of the pages on my website. There is also a Try/Catch block within this code that currently contains an 'Exit Sub' in the event of an error being trapped. However, what I would actually like to do is to merely exit the current loop value and recommence the loop at the next value in the sequence.
How can I do this?
what if you created a pool of numbers: 1 - 21 and then chose a random selection from the pool? Something like the following:[code]This gets rid of those messy if statements and all of those loops.
View 1 RepliesI have the following problem:
I've got 3 lines
If I click the "next" button
Line 1 shall be highlighted
Then I I click ""next" again
[Code].....
a for i = 1 to 3 to loop within the Button1_click makes i directly 3 of course so line 1 and 2 will not be highlighted.
I am not allowed to use a msgbox in between cause then it would be easy, cause I would wait until "OK" would be pressed...
How can I make this for i = 1 to 3 loop work and highlight the lines 1, 2 and 3, one by one after pressing the "Next" button?

I am creating a small applicaiton for simulating dice roll. To simulate bounces I change the position of the picture randomly. Now to simulate more than one bounce, I used a for loop to continuously change the position of the picture box. But it is not happening as I planned, the form only displays the position of the last loop. I even tried using System.Threading.Thread.Sleep(1000) hoping to show the bounces, but even they show the last loop only.
For bounceCount As Integer = 1 To bounces
bounce(pb_dice1)
bounce(pb_dice2)
System.Threading.Thread.Sleep(3000) 'I need to pause here and show the recent change in position then continue after 3 seconds
Next
the bounce method changes the position of the PictureBox.
How can I pause my for loop, display the newly positioned dices, and then continue after 3 seconds?

an application i developed using vb 2008 express, to fill a web form with data from an access database, one after another when a button is clicked hasn't given me what i expected. the loop was suposed to stop after filling web form with the first data on clicking a button and continue to fill the webform with the next(2nd) data from the database on clicking the button again. Below is the code i wrote
Private
Sub STARTButton_Click(ByVal
sender As System.Object,

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

View 3 RepliesI am making a Tetris program and I have a 2d array 10 by 20 for the grid.I want the Tetris blocks I have created to move down one block every second unless the user presses "a" or "d" (to move left or right) then the block should move left or right whilst moving down.The problem is that I have created a loop for it to delay a bit but then it waits for the user to press a key until it continues the program. So the block will stop moving down and just stay where it is until they press something.I have been told that you can do this in C with something like if keyboardhit or kybd() or something then it will read the key but otherwise it will just skip that bit and loop round. So how can I do this in VB?

When you are putting in a long string of code it doesn't all fit, so I want to know if there is a way to continue that string on the next line. I believe it's something like & _ if I'm correct in thinking. But I'm not perfectly sure, I guess the question I'm asking is if you can continue a string with & _ or if it is something else.

View 2 RepliesI'm writing in Visual Basic, using Visual Studio Standard 2008, targetting framework 3.5.When debugging, I pause code and edit it in my Startup Project, then continue running.Where the code moves into one of my non-startup projects, I am sure I used to be able to edit that code and continue running.Now, whenever I try and do that, I get a dialog stating that "Changes are not allowed when the debugger has been attached to an already running process", even though I can still edit code in the already-running startup project.All of my code is in VB, there's no weird language crossover thing going on. Why can't I edit-and-continue my non-startup projects?

64 bit is a wonderful thing, except that MS currently has no plans to make a 64-bit IDE. However, you CAN compile your program to be 64 bit using AnyCPU or x64 compile options. However, by using either of those options, you cannot edit-and-continue.To enable edit-and-continue on an x64 machine, you must set your compile option to x86 in the Platform property of 'Project Settings > Compile'. If you do not have that option available, be sure that you select 'Tools > Options > Projects and Solutions > General > Show Advanced Build Configurations'.

View 2 RepliesI am using the MsgBox Function as a help on my program to notify users of unusable entries in my program. After the MsgBox pops up, and the user clicks on either 'OK' or 'Cancel', the program need to clear the box that the bad data was entered in, and continue with the program. What I am trying to do I guess is keep the program from returning unusable values by informing the user of entries that will return such values. But, where I am running into a problem is in when I click on OK or Cancel, the program continues as if nothing was called as a result of the MsgBox info being thrown.
Here is the code I have so far, mind you that I have used several of the other MsgBox codes to no avail.
I think what I need to do is have a line of code that calls my "textbox.clear" if certain criteria are met. but when I tried this, the program did not return to my GUI, it simply ran with a value of "0" in the "textbox.text" that the clear was called on.
The idea with System.IntPtr is to represent an integer whose width in bits correspond to the size of a pointer in the hardware and operating system that the CLR is running in, it's platform specific in other words. It supports 32-bit and 64-bit architectures only.This is a legacy from old-style C API's where pointers and ints were frequently treated as interchangeable. The Win32 API has many such parameters, where the width varies with the underlying architecture thus the mess with porting of code from 32-bit to 64-bit (we already did this once when going from 16-bit to 32-bit, funny how we never learn...).In practice, as is mentioned in other responses, it can be used to hold unmanaged resource handles and pointers etc that stem from the underlying Win32 functions. It can also be used to hold integers of the natural size for current platform. You can also use IntPtr.Size to dtermine the size of a pointer on the current platform.SO when you explain this to a child ;) this would be used to let program's flow at the same speed at diffrent kinds of operating systems?
