The following loop starts in x then loops thru y 20 times then goes back and finishes x. how do I get it to loop thru x then complete loop y then loop x once more then loop y completely again 20 times then back to x and another 20 ys. there should be 200 loops today.
CODE:
I need to figure this out as part of a larger program.
[Code]...
how many times is the loop executed? what is the value of i after the code is executed? if x and y are dimensioned as dim x(10),y(10,2) as integer, what would happen in the code? what would happen in the code if the first statement was for i = 14 to 12 step 4?
In the first loop once it cycles through once it does not reset the data so it continues to hold the previous data so therefore the outcome is incorrect. Can I reset it to start back at 0?

However when the program hits the last value of 'For loop 1', the nested for loops seem to only trigger once instead of the number of times that i specified.

I've written a keydown event that needs to occur multiple times during the execution of a program, and it needs to play a sound each time. The first time the keydown event is triggered, the sound plays without a hitch. However, the second time (and all subsequent times) the keydown event is triggered, a system beep accompanies the sound. I'm using Studio Express '10 and I've already integrated e.SuppressKeyPress into my code:

I want to display a bitmap on my form, and then remove it at times, and put it back again.
I have the Bitmap in my resources folder.in my form properties, it is selected as background image.
somewhere in my code I set the background image to = nothing (that makes it disappear) but every time I try to bring it back, I get file not found.I got it to display when I hard-coded the entire path and filename.[code..]
Obviously, when I publish and distribute to clients, the file won't be there.[code...]
I need a small app that randomly shuffles a set of preloaded numbers. The shuffling will be visible on the screen and goes on continuously (looping) until a key is pressed and as soon as that happens it will show the winning number.Am using visual basics 2008 to develop the application but my problem is when i start the app and hit a key it will loop through my numbers on the text file and it will also display the event but if i hit a key to stop it will not stop..I was workin on the app but my problem is how to stop the loop and resume on the with a keypress. below is the app codes.

how many times is the loop executed? is this 4?
final value of i? 9?

View 1 RepliesI have about 1.000 text files in a folder, and I wanto to make some statistics reading the files content.In the first place I store the files path + name in a MyFiles() array, then, when I press a "Start" button I read the several files:
For x As Integer = 0 To MyFiles.Length - 1
FileReader = My.Computer.FileSystem.ReadAllText(MyFiles(x))
(data processing)
(data processing)
next
then I have copied and pasted the first 500 files in a new folder and added to the code if x > 500 the stop The strange thing is this: to elaborate the 500 files of the second folder takes about 4 seconds, to elaborate the first 500 files of the first folder (THAT ARE IDENTICAL TO THE 500 FILES OF THE SECOND FOLDER) takes 7 seconds.The same identical code takes different times to elaborate the same identical files if they are stored in different folders with different files number.
i want to do this with the delay of in interval with the loop of 10 times.

I have 3 classes that need themselves in order to do their work but if I declare them the old way it would end up being an endless loop.
As an ex C++ programmer, I know I could use include once but I don't know if there is any equivalency in vb.net Here is the picture.
I have 3 Classes : SQLConnector, ErrorHandler, LogHandler
- ErrorHandler needs SQLConnector to get some IDs from the Database.
- ErrorHandler needs the LogHandler class to prepare the Logs to be... logged.
- SQLConnector needs the ErrorHandler class in case there is errors happening.
- LogHandler needs SQLConnector to insert in the database.
- LogHandler needs ErrorHandler in case the insert is not successful (sends mail in that case)
As you can see, all three classes are needed. The reason why I can't use LogHandler and ErrorHandler as one class is that I will use that class to log transactions and changes according to some parameters. Log is in no way exclusive to ErrorHandler.how I can prevent to make an endless loop and use all three of them as I wish?
I have made an app that the user has to type a number, and i want the process for the app to do this how evermany times the user wishes it to do.
for example, the app is ment to create a line in a text document, so they write in textbox1 what they want written on the line, and then in textbox2, tey say how many lines they want to create.
So,
TextBox1.Text = "BLAA"
TextBox2.Text = "782"
It will create 782 lines of BLAA. not just one...

i have a button in my form which increases the font size of the form by 1. [Code] now when i increase the font size, after increasing by 3 the size of text boxes starts decreasing. this is how the form looks after size+5, when i open the form, the tabpage resize event is called 3 times.
View 1 RepliesI have a datagridview with checkboxes in the first column and I want to do a loop on saving the serialnumber(s) when the users decides to check a number of checkboxes Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)
So I have some vb.net code, and I have a nested For loop inside a For loop, and then I have EXIT FOR statement, will it break out of one loop, or the whole chain?
