Using The Offset Property Of Scroll Bar?
Jan 12, 2011
In my vb.net project, i am using tab control and some DGVWs, command buttons. i use to dynamically place these controls into a tab page and set the autoscroll proprty to true. once the scroll bar grown and when i try to scroll down the bar to view the bottom most controls, the scroll bar automatically retriving back to its original position. i have to click 2 or 3 times in the bottom of the tap page and scroll again to view the bottom most control. i am unable to figure out using the offset property of scroll bar.

I use drag'n'drop from a datagridview to a panel. The panel holds an array of objects (think rows) so that the items from the datagridview can be dragged to the different objects. I use the y-index from the top of the panel to define what object the item is dragged onto.This works great as long as the object is visible from the start. However, if I scroll down to an object and then drag the item from the dgv, it gets released on the wrong object, as the y-index doesn't take into account the number of pixels I scrolled down. So, what I need is (if it exists) the scroll offset property for the panel, i.e., the number of pixels that I scrolled down. (Then I can add this offset integer to the y coordinate on which the user drops his/her object.)

I need to use a Vertical Scroll Bar to scroll through some controls (an array of checkboxes to be precise) on my form. Their number changes depending on the user's requirement during program execution so I need to change the Maximum value of the scroll bar in my code. Also, the SmallChange property needs to be modified depending on the set maximum value (other wise scrolling through the controls will take ages ).

I have a tab control with two tab pages. One page has the auto scroll enabled since there is to much content in the page. The middle mouse wheel doesn't scroll the scroll bar; I have to actually click and hold the scroll bar and drag it down to scroll. Is there a property to allow this?

I am having an odd problem with the Horizontal Scroll Control in my program.I am using it to scroll a series of panels across a form.This is my code:
Private
Sub scrHoriz_Scroll(ByVal
sender As[code]....
The problem is that this works perfectly if I use the left and right arrows and it also works perfectly if I use the scroll bar's slider SLOWLY. If I scroll using the slider and move it quickly then the scroll gets out of sync.The small change and large change are both set to 1 and maximum is set to 8

I have a DataGridView with a panel above it, that contains a group of textboxes above each column. My DataGridView has a horizontal scroll bar. What I want to do is when the DataGridView scrolls horizontally, scroll the panel with textboxes above it, so they stay aligned.I tried handling the DataGridView's scroll event, but I'm not sure what to do with it.

I am loading several command buttons into it (one in each grid box). I have the panel set to autoscroll. When TableLayoutPanel is set to AddColumns, all works well. However, I dont want horizontal scroll, I want vertical. When I set TableLayoutPanel to AddRows, a vertical scrollbar will not appear.

How would I leave the vertical scroll position as it is and set the horizontal scroll position all the way left if it isn't already in that position? I've been using Me.AutoScrollPosition and have come up with code that is satisfactory but I haven't been able to always leave the vertical scroll position exactly as it is and just move the horizontal scroll position to the left limit.

I have a textbox that shows events on a program, which I add. I use the 'scroll bar' option on the textbox to show the vertical scroll bar, but how do I make it stay at the bottom most possible? I am using this code while I am trying to learn how to do what I want the scroll bar to:[code]But how do I get it so the scroll bar will stay at the bottom-most it can? I'd like the newest, most recent events to appear at the bottom of the textbox, and to have the user not have to scroll down every time something new is added.

i have 2 controls on a form. Panel1 and picturebox. I am using the following code to zoom in.
PicBox.Width = PicBox.Width + 100
PicBox.Height = PicBox.Height + 75
'PicBox.Left = PicBox.Left - 50
'PicBox1st.Top = PicBox.Top - 20
i am also using the following code to try and scroll whilst zoomed in
Inherits System.Windows.Forms.Form
Private m_PanStartPoint As New Point
Private Sub picbox_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PicBox.MouseDown
'Capture the initial point
[code]....
I have set the panel to autoscroll and added scroll bars but they do not scroll far enough... They only scroll about 2cm.

I have an app with clocks on it from around the world. It's used in multiple locations around the world as well, some that observe DST, some that do not.
Is there some way to get the current offset for various timezones from the OS? My preference would be to simply use the OS to GET the offsets, thereby relieving the program of having to figure out the dates and when to reset the clock. That would eliminate the need to be concerned with DST altogether; the offset values could simply be added to the current datetime.utcnow. I'd need to get the offset/current time for Hawaii, Pacific, Mountain, Central, Eastern, UK, France, Germany, Mumbai, China and Australia time zones.
TimeZoneInfo.GetSystemTimeZones can get at some of this data; is there maybe a way to cull it out of that?

How can I get the sum from richtextbox, starting at line -1 ? But the first line should compare with line1.This code adds a constant to all lines and passes the sum to another textbox.
Dim num1 As Single
Dim sum As Single
Dim Constant As Single = Val(txtLowerTol.Text[code]....
So a third textbox should sum with one line "offset".

ArgumentException:Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection." what i realy want is to write 9 bytes from the clint received data to the serial port then read 19 bytes from the serial port to send to the client even if this error ocures the program still works fine and the interface between the serial port over the network also works fine, but i don't want this msg to view that the my code .[code]

I've got a function that's supposed to extract and return a 32x32px bitmap from a larger bitmap which has a set of 32x32 tiles inside it.
Here's the code I have now, but it's wrong since the Tile.GFX_Pos properties are telling it where in the destination image to draw, not where in the source image to draw from.
Overloads Shared Function TileGFX(ByVal SrcGFX As Bitmap, ByVal Tile As TileDef) As System.Drawing.Bitmap
Try
[Code]....
So since this doesn't work, what I'm wondering is if anyone knows a good way to select where in the SrcGFX bitmap to blit from, instead of (as currently and incorrectly) selecting where in the destination bitmap to blit to.

In VB6.0, you could create a sub that took an array byref, and then call it with an argument that was an indexed element of the array, and it would treat that index as the starting point. This was very useful, for example, if you were trying to create a binary string to send over a communication port.The same thing doesn't work in VS 2008,Let us say for example I have the following Sub:
Public Sub HexToAddr(ByRef addr() As Byte, ByVal addrstr As String)
Dim i As Integer
For i = 0 To 7[code]....
Is there some tricky way to make this work, or do I really have to either (a) create a completely separate array of bytes, call the function, and then copy the data, or (b) create a completely separate version of HexToAddr which takes an "offset" argument for the destination array?

I have a string:
0E0100000000000000000003CB7352
I need to be able to look at Offset 14 and Length is 1B. I need to be able to look at bit 0 - bit 5. I have NO idea how to read data like this so I wish I could be more specific but I can't. Can someone tell me how to read the specific bits and translate them? I have no idea how to google this. So if someone wants to point me to a search pattern. That would be awesome too.
Here is a chart that describes the bits:
bit 0 : Light LED (head) status, 0: OFF, 1: ON
bit 1 : IR-Radar power status. 0: OFF, 1: ON
bit 2 : IR-Radar detector status: 0: fine, 1: barrier detected.
bit 3-5: Charger staus
0x00 : nothing happen
0x01 : charging completed.
0x02 : in charging
0x04 : something wrong, error occur.
bit 6,7: undefined, do not use.
