I have an application that contains both test code and production code. The test code points to the test files on the local machine while production is located on the server. I comment out the production code when testing. To save some time I figured I would create a Global Variable integer called pTest and encase the test and production code in a Case statement so that if I set pTest=1 then the test code will run and if pTest=0 then production code will run.

I think I've seen something like this before - where the actual function returns a value. Is this possible? Or would I have to pass an integer variable from the sub to the function, and then return it back to the sub?

View 4 RepliesIs it possible to make a variable hold a reference to an integer instead of copying its value when using integerVariable = integerValue ?
View 2 RepliesI have a problem when debugging a code. On top of class I declare an array, and the length of array is an integer variable which is applied value below declaration of array.
E.g. class declaration
Dim array1 (2, integer) as string
Public Sub
integer = 5
End Sub
So basically, array is created with integer being 0 or whatever, because it is declared before integer was assigned a value. But the problem is, I need it to be declared at class variable so I can use array in different subs.
Is there anyway to customize a variable to use both an integer and a boolean value?For example. I am kind of making a simulation engine and using GDI as a visual aid, I am generating a grid of tiles for objects to be displayed, but I do NOT want to repaint all the tiles just the ones that have changed, so that I can save fps.So I thought if I could set a variable for the "tile number", "how many objects there are on a tile", and a boolean value for whether or not the tile needs repainted.[code]
View 2 RepliesIs there a way of testing to see if a number variable is an integer, or a decimal?
View 8 RepliesI want to assign the value of the integer returned from the InStr method to a variable. So, If TextBox2.Text = "The Apple Pie" And TextBox1.Text = "App", I want the integer returned, which in this case would be 5, put into a variable, lets say its called 'VarString'.
So VarString (would) = 5.

I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).
I am a .net beginner trying to make a crossover from vb6. I am trying to copy bytes of integer to a variable but I am getting this error msg. PInvokeStackImbalance was detected
A call to PInvoke function 'Tutorial_Class Dog!WindowsApplication1.ModAPIFunc::CopyMemory' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

I know vb.net does not include pointers like C language. but I am trying do populate an simple integer array with variable of the same type for example :

dim variable2 as integer = -1

it is a very simplyfied verson of what I want to do.I want to change the value of ma variables with my array referencing them with an index as if my variables were pointers of integer in c++ for example so that normally after the example, both variable should hold the number 3 instead of the number -1?

View 2 Repliesmy function is to adjust a timer interval according to a integer variable.
Original code (works fine):
Code:
Dim UpdateSnakeSpeed
Select Case UpdateSnakeSpeed
Case currentscore > 199
[Code]....
This is the code I'm using right now. (works fine and is more logically correct than the above case statement. I have chosen to go with if .. end if statements over case, as I do not have a full understanding of what the variable SnakeUpdatespeed is doing in the Select case statement. If someone explains then I'll consider it. Also I know case statments are only meant to be used for 1 option selections, however I'm amazed that it still works in case. Atm it's going to be if end if. Now I'm trying to get the for next loop going with this (if it's logically possible). that's what i'm aiming overall out of this thread. To make a convenient loop.
