Stop A Loop Statement In VB And Not Perform Display Changes Until After Call Procedure Is Valid And Complete?

Apr 19, 2010

I am having problem with the coding of this (endless loop) and formatting of summary boxes before tests are complete that should not happen. (the overall goals is to have a separate validation procedure that does not calculate or dat displays are not performed until after call function is complete and valid. The validation that takes place are that two boxes are filled in - one is text and the other is a numeric value. (using vb 2008)

Call A Stored Procedure To Perform Count On An Array?

May 21, 2012

I am selecting a distinct user from IT_Cases_List and stored it in an arraystaff(). From this array, I will then call a Stored Procedure to count the no of cases attended by this user,(arraystaff(i)) and loop it until arraystaff.length-1

but the problem is that the count does not tally.

Sub getStaff(ByVal month As String)
If Not con.State = ConnectionState.Closed Then
con.Open()

[Code]....

ok, i've called only once getcases but i'm still having the same problem.

this is what i get when i run the program:

if i get Count(*) from the database, the total no of cases i should be getting is 132, whereas the total of cases i get from the program is 157 (7+7+20+20+49+49+5)

if i run the query from sql, this is what i should be getting

i notice that the Count number gets duplicated (7,7,20,20,49,49,5) instead of (7,20,49,5,10,27,13)

Main Procedure Call A Sub Procedure To Display Values Of X / Y And Hypotenuse

Dec 1, 2011

The instructions are as follows:

1. Write a Visual Basic Console Application.Inside the main procedure call a function procedure to input and return a value for a double variable called x, the width of a right triangle.Inside the main procedure call the same function procedure a second time to get a value for a double variable called y, the height of a right triangle.

2. From the main procedure call a function procedure which calculates and returns a value for the hypotenuse equal to the square root of (x squared + y squared).You will have to pass the values of x and y to this function procedure.The procedure should calculate and return a double type value.The value that is returned by this function procedure should be equal to the square root of (x squared + y squared).

3. Also from the main procedure call a sub procedure to display the values of x, y, and the hypotenuse.

How To Do An If Statement That Does't Call A Procedure

Nov 13, 2009

I have a form which obtains data from text boxes and stores them in a file. If fields are missing, an error message is displayed. When information is stored, a message box asks if the user wants to enter another customer. However, that message appears whether or not information has been stored - I've used the following code. [code] Is there a way to not call the procedure if the error appears?

VS 2010 - Call Valid Only As First Statement In Instance Constructor

Jul 19, 2011

I'm trying to create an array to be handled during my code. I want to create it as soon as I open the program so I've placed it in my bit of constructor code. This code was working fine before I tried to initialize a new array in there but when I place that in I get the above error message. This occurs whether I put the new array bit of code first in my constructor class or not.

"Procedure Call Or Argument Is Not Valid" Error?

Why Is Constructor Call Valid Only As The First Statement In An Instance Constructor

Nov 2, 2009

what's the rationale behind this limitation: Constructor call is valid only as the first statement in an instance constructor i want to pass an argument to my constructor which validates this argument and calls mybase.new according to this argument but it doesn't let me

example:

Public Class prob
Inherits System.ApplicationException
Public Sub New(ByVal problem As String, ByRef inner_exception As Exception)

Loop Statement - Display A Table Giving The Balance On The Loan At The End Of Each Month

May 17, 2010

I am trying to create a program in vbfor this problem: "A TV set is purchased with a loan of $563 to be paid off with 5 monthly payments of $116. The interest rate is 1 percent month. Display a table giving the balance on the loan at the end of each month". It must have 1 button and a list box that displays successive balances, contains loops to balances, loop code includes output to the list box, List box displays 2 columns (one for month and one for amount owed) and 5 months are displayed and the amount owed for each. The Amount Owed should go down each month from month 1 to month 5 where month 5 will equal to $0.00

Here is my code so far but somehow the 1 percent interest i cannot get to add on each month so I am not getting the write answer.

Code:
Dim rate As Decimal
Dim loan As Double
Dim pay As Double

[CODE]...

I have attached a jpeg of what the end result should look like when code is being run.

VS 2010 : Use A Stop Button To Stop A Loop?

Dec 7, 2009

I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.

Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.

Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

#End Region
Declare Function InitStp Lib "stp.dll" () As Integer
Declare Function RunMotor1 Lib "stp.dll" (ByVal steps As Integer, ByVal interval As Integer, ByVal direction As Integer, ByVal outputs As Integer) As Boolean

Determine Whether A Conversion Is Valid Before Attempting To Perform It

Aug 25, 2011

I have the following subroutine:

[Code]...

The intention is that an event handler is set for any control added to the form, but only if it's a certain kind of control — determined by what its most-derived type is. Putting overarching design concerns aside for the time being, although this subroutine functions properly, when running the debugger the constant exceptions keep leaving messages in my "Immediate Window". It's annoying, and presumably throwing exceptions only to immediately re-catch them is wasteful.

Timer - When The Message Box Stops, Then It Display The First Form Then Stop To Display?

Apr 8, 2011

I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:

Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....

I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
