Can PointF Be Used To Determine The Position Of A Button
Nov 25, 2010
I am using a button together with a mediaplayer. The button represents the media player currentPosition. (I know this is already a built in feature of the media player object but I need a much bigger display area.) It works as planned and allows the user to get or set the currentPosition. The only aspect I'm not happy with is its jerky movement as it jumps from pixel to pixel. I thought I had solved the problem by using a PointF (MyButton.Left = MyPointF.X) only to discover that the MyButton.Left value is reconverted to an integer (i.e. a position in pixels).
Is there any way that objects like buttons can be positioned accurately using units of less than one pixel?
If not, is there any other kind of object that can be positioned more accurately than a button?

I'm writing a text editor for my own use ( I'm "home learning") where I want to be able to leave comments for myself, like in code section of the VB express IDE. I have figured out how to get the Integer Location of the apostrophy, but can't get it to color the rest of the line. I don't know how to tell the program to find the integer value of the last character in the line. I need that to be able to subtract the apostrophy's location from the last character's location, to get the "SelectedLength". Then I can add that to the apstrophy's location to give the SelectedLength the SelectionColor.This code was thrown together from excerpts of several codes I found on the web. I had to rewrite everything to get it to do what it does so far...
Apostrophy Location is char # 534 , the end of the line is 547. ( I cheated to get that count by placing another apostrophy there, and reclicking the btn. )Anyway, I want to take 547 - 534 to get (13) the SelectionLength, then give the SelectionColor ( green) to that selected text.
[CODE]
Dim Location As Integer
Dim char3() As String = {"'"}
Dim z As Integer = CStr(vbCrLf.Count)
[code]....

am i right to say that the main difference between point and pointF, is that Point holds integer values for X and Y and PointF holds Floating values? =)

i have an if statement that neds to check if the control passed is a checkbox or a radio button
If TypeOf (Control) Is CheckBox Then
If count = 1 Then
text += Me.GetCheckBoxValueJQuerySyntax(Control.ClientID) & " + '~' + "[code]......
This fails as the checkbox and redio button derive from the same class, so how woudld i check if the control is a checkbox or a radio button.

I am creating an application that takes two numbers (lower and upper) and determines the prime numbers
Public Class primeNumber
Private Sub calculatePrimesButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles calculatePrimesButton.Click
'declare variables
Dim number As Long
[Code] .....
Once I hit the calculate button nothing comes up. I've tried adding the first code inside the function with the remaining code but no result. Now I'm putting the first code in with the calculate prime button. I am guessing there's a sqrt method that needs to be applied but I am not sure if it should be part of the function or the main?

I would like to make data binding using BindingSource whereby whenever either Next Button or Previous Button is click the BindingSource position will change to display the data at that position.
I know that if I want use a loop of the BindingSource I could do somthing like vb code below but I am not sure if of binding it seperately. I usually bind it through the properties but this I cant because is an image column which I want to bind and I have to us memorystream to display it to reduce memory usage, so I asign it to arrPic so that whenever the BindingSource position changes the image column will be asign to arrPic.
Dim MyRow as DataRowView
For Each MyRow In dtView
'only use non-repeating names
CurrentPicture = Trim(CStr((MyRow("FileName"))))
If CurrentPicture <> LastName Then
[Code]...
The BindingSource filter the picturenames and add to a listbox. One name may contain about 4 or more pictures so when you select a name from the listbox the bindingsource populate only the pictures have the selected name and you can navigate forward and backwards.All what I want is how to bind a column to a textbox or picturebox by code. I know if it is a dataset I can declare a datarow and bind anything to the columns.

I have one form with one tabControl with two tabs, in each one I have one dgv, in the visible change event I create and add a new button column, that will be placed at the end. Now the "problem", if the first tab it's selected when the form becomes visible, the column it's placed in the correct position (last), and in the second tab the column it's placed in the third position.
If I do this with the second tab selected when the form become visible, the column it's placed correctly in this one, and in the third position in the first one... The code that I use, it's very simple, every datagrid it's bounded to a datatable, I tried the add method, then I tried the insert method, then I manually set the display index for each column, and none of this options solved my problem...

I have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:
1. Multiple monitors. (and resolution between those monitors)
2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)
3. Sometimes the programs dont open on the right monitor they were closed on.
Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?

I also have a function that returns ALL tiles on the map and they're X, Y position. How could I find out which one is closest to the position I specify? I can't figure out how to go about it. how to implement it with this. Heres a MADE UP example if what I'm trying to do:
Dim MyPosition as New Position()
MyPosition.X = 400
MyPosition.Y = 400
Dim tList as New List(Of Tile) = MyMap.GetTiles
Now, I can already do the stuff above, but what I need to make is something like this:
tList.GetTileClosestToPosition(MyPosition)
