I am wanting to increment an integer by 1 each time i press a key. My problem is this, when i press the key, the integer is increased by a lot, unless i just 'tap' the key very precisely.
Is there a way to 'reduce' the sensitivity of pressing a key?
I want to Use Progressbar1.Increment but I wanna use Integer but the problem is that the maximum value of integer is over 100 so i want to set the Integer.Maxvalue to 5 but it got an error when I tried using Integer.MaxValue(5) and Integer.MaxValue = 5, So I need to the the Maxvalue to 5. I use Vb 2005 Express Edition.
View 3 RepliesCan a VB.NET For loop be constructed that mimics this C# code?
TimeSpan oneDay = TimeSpan.FromDays(1.0);
for (DateTime d = startDate; d < endDate; d += oneDay) {

Obviously you could do it without a For loop (i.e., with a While); I'm just curious if there's a certain syntax to construct a VB.NET For loop with a non-integer increment that I'm not aware of.
I have a visual basic .net application. It has a sql server database and a dataset for it. I have created an interface to the database (passing through my dataset) to add, delete, save etc records in a table.
The ID entry has identity specification:Yes and increment seed 1 When I add a record, instead of giving 1,2,3... as id in the textbox it produces -1,-2,-3 (Negative integers)

2. How do I make my autotyper press enter every single time after the textbox message was typed?

I'm working on some code in VB that can get the average time from the speed of button press. I've got the maths done however I'm having a problem converting a TimeSpan declaration into a Integer where it can be divided and made into a average.
Maths for code:
2nd click
click count = 2
average= current time / 1
so current = time click count - 1

I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?

I'm just writing a bit of code to compare an id of integer with an id of integer? for example:

When I try to compile the code I get a compiler error: Option Strict On disallows implicit conversions from 'Boolean?' to 'Boolean'. Whilst it's very simple for me to work around this, I was hoping that someone might be able to explain what's going in the compiler to give this warning.
