Forms :: Choosing The Amount Of Times A Loop, Or Sub Should Occur
Mar 29, 2009
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'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:

System.EventArgs) Handles Button2.Click

I'm trying to design a windows form application. By default, .NET had put Tahome 8,25 on toolbar and Microsoft SansSerif 8,25 on everything else. To improve general look and feel of the forms I'd like to change them.
Which font family should I use as a default? And what size should they be?
For:
Classic data input form (label + textbox, label + combobox...)
Data grid
Is there any recommended way?
Application is a classic business app, you can think of it as an accounting type.

I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?

OK, after trying to get this working for a couple of days now I decided that I would turn to the experts here. I am trying to create a nested loop with a variable amount of nests. Let me elaborate. I have a program that first asks for the minimum and maximum amount of loops, I currently have a SELECT CASE statement that addresses each level of nesting individually.
Dim cMin As Integer = InputBox("Min")
Dim cMax As Integer = InputBox("Max")
Dim c1, c2, c3 As Integer

i = 5, j = 15
do while (i<j)
i=i+1
j=j-1
end while
how many times is the loop executed? is this 4?
final value of i? 9?
final value of j? 10?
when would you do a do while versus a for next loop?if the upperbound of a one dimensional array is 10, what is the size of the array? 11?CAN I GET HELP WITH THIS
dim x(20,2), y(20,2) as integer
dim i as integer
for i = 4 to 12 step 4
[code]....
how many times is the loop executed? 3?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?

I 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 have a problem with trying to get 2 forms to close at different times using a timer on each of the 2 forms.
This is my form layout:
Quote:
frmMain
Frm1
Frm2
Frm1 and Frm2 are identical to each other. FrmMain has 2 buttons on it. One button to call Frm1 and the other to call Frm2.Frm1 and Frm2 each has a timer. It counts down to 0 and then does a .close(). However, if i pause between clicking the second button they both seem to always disappears at the same time.I would do something like this...
Click on the first button (showing the Frm1 form)
wait about 10 secs...Click on the second button (showing the Frm2 form)they both are shown on screen...hen they both disappear at the same time.... which shouldn't happen since i clicked the Frm2 box 10 seconds AFTER Frm1... So Frm1 should hide before Frm2 does...but it does not.

I 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)

I have a string which I have pulled out of a text file as shown below,[code]and I would like to split it up and get the numbers into individual string() arrays. I have tried using split , but the problem with this is that it only splits up characters with one space between them, and there could be multiple spaces between characters so it ends up storing blank spaces it a string array.[code]
