What is the point of the max value of a scrollbar when it can't be attained? I put a horizontal scroll bar on a form and set the maximum value dynamically. After a bit of testing, there is no way for the scroll bar to attain this maximum value. Instead, I am always ending at Max-2. It always comes up two short. So what is the point of the maximum value if it can't be attained?

How do I set my horizontal scroll bar to have the values increment between 1 and 100 and then have a label (lblFuelChosen) updated according to the value chosen on the scrollbar?
I have a label that is named lblFuelChosen and I have a horizontal scrollbar underneath it. I need to set the scrollbar to increment in values between 1 and 100, and the value to be placed in the lblFuelChosen label. How do I set the scroll bar values and how do I set the value to the label?
I have a horizontal scrollbar on my form, and the form is longer (vertically) than the screen. What I'd like is for the horizontal scrollbar to always be visible at the bottom of the screen, no matter where the user is vertically. Right now, the user has to scroll all the way to the bottom of the form in order to see the horizontal scrollbar.

View 1 RepliesThe scroll bars actually move now, They just move the wrong thing. When I click the Horizontal bar it moves the picture box to the left part of the screen and I can scroll the box back and forth. If I click the Vertical Bar it goes up to the top and I can move it up and down. So if I click both of them, the picture box goes to (0,0) of the form. It wont move the image inside. I can't figure out how to assign the scrollbars to the image instead of the picturebox.
Try making a form with a Picturebox, Vertical Scrollbar and Horizontal Scrollbar in it and rename all your stuff the way I got mine:
Horizontal Scrollbar = hsbPicMap
Vertical Scrollbar = vsbPicMap
Picturebox = picMap
Set the image property in the properties box to whatever you want. Try to make the picturebox of fairly big size. Mine is set to 656, 528 in pixels, and the location is 152, 72 on the form. The image I am using is about 1500, 1200. The bars are on the right side and the bottom of the picturebox.
Code:
Public Class frmMap
Inherits System.Windows.Forms.Form
Private Sub HSBpicMap_Scroll(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ScrollEventArgs) Handles hsbPicMap.Scroll
picMap.Left = -hsbPicMap.Value

I'm using a RichTextBox and wondered if it's possible to change the height of the horizontal scrollbar. I don't hve much room to fit the RTB so I need to reduce the height of the scrollbar.
View 2 RepliesI'm using a TLP and it contains controls that exceeds it's height, so it's normal for a vertical scrollbar to be displayed. So far so good, but i can't figure out why a horizontal scrollbar is also being displayed when my controls width do not exceed that of the TLP. Is there some way to remove this horizontal scrollbar?
View 5 RepliesI'm having a problem assigning the arrow keys to the right scrolling events.I have a VScrollbar and an HScrollbar. I want the left / right arrow keys to scroll the horizontal bar, and the up / down arrow keys to scroll the vertical bar. The default behaviour seems to be that the first created of the two (VScrollBar or HScrollbar, depending on order of creation) received all arrow key events as a Scroll event. So when I push up / down / left / right, it is my VScrollbar that moves (HScrollbar might move also with the left / right arrow keys, I don't remember). I tried catching the KeyDown event on my form, to manage the left / right / up / down keys myself, but apparently the Scroll events are triggered first...In any case, what would be the "right" way to use a vertical and horizontal scrollbar and have the arrow keys do what they're supposed to do in VB. NET?
View 2 RepliesI'm using a DataGridView in VB.Net in VS 2005. The issue is, when there are rows that exceed the width of the DataGridView, the horizontal scroll bar doesn't appear (the ScrollBars property is set to "Both"), but an ellipsis appears at the end of each row that is too long. I don't want the ellipsis, but the horizontal scroll bar. The vertical scroll bar works as expected when the number of rows exceed the height of the DataGridView.
I have tried setting numerous related properties (changing the AutoSizing property of the DataGridView, Resizability of the Row Template, made sure that no Columns were Frozen) to no avail.
I am working DataGridView in vb.net08.The intresting task is ,When i move the Horizontal Scrollbar in DataGridView from Left to Right ,the First two Columns should be stable and moving starts from 3rd Column.Means If i moved at end of the right side but the first two columns should be visible. When i move the scroll bar the first two columns should not be disterb.Is there any property like Scroll bar position should be starts ??I tried the " FirstDisplayedScrollingColumnIndex" property but it only starts the Scrollbar from giving column index after moving the scrollbar the first two columns are moving into left side.
View 2 RepliesNot so much a VB question more of a Net question.Does anyone have a logical explanation as to why the Maximum value of a Scrollbar is impossible to reach by user interaction?The documentation explains clearly the how, it just gives no reason for the why.
View 3 Repliesso I created a new control. When the user changes the font, I don't want the user to change the font past font size 14. If the user changes the font past 14, the font should reset to 14.Here is what I have so far.

I've had a look around, once again and can't find how to set the minimum and maximum dates allowed to be selected on a calendar in ASP.net with VB.
I'm using Visual Studio 2010 and it's just a regular Calendar control at the moment...
At the moment I've seen things like:
Calendar1.DateMin = DateTime.Now
But Visual Basic doesn't seem to like that (maybe it's a C# thing?).
I have a list box on my form with 2 value - "2010" & "2011". When I change the value in the listbox it should set the minimum and maximum value of 2 datetimepickers. Each time I try to change the value I get an error - for example if I change the listbox from 2011 to 2010 I get the error:
"Value of '31/03/2011 00:00:00' is not valid for 'MaxDate'. 'MaxDate' must be greater than or equal to MinDate. Parameter name: MaxDate"
If ListBox1.SelectedIndex = "0" Then
DateTimePicker1.MaxDate = #3/31/2011#
DateTimePicker1.MinDate = #4/1/2010#
DateTimePicker2.MaxDate = #3/31/2011#
DateTimePicker2.MinDate = #4/1/2010#
End If
If ListBox1.SelectedIndex = "1" Then
DateTimePicker1.MaxDate = #3/31/2012#
DateTimePicker1.MinDate = #4/1/2011#
DateTimePicker2.MaxDate = #3/31/2012#
DateTimePicker2.MinDate = #4/1/2011#
End If
I want to set minValue and maxValue of text boxes to define a range of acceptable values for validation purposes.In VB 6 this is straight forward and can be done under text box properties, however in visual studio vb .net 2010 this is not the case or it may be the case that i am missing something.

View 4 RepliesI'm using LINQ to Entities to generate typed result sets in VB.Net. I've got a generic Report class as follows:
Public Class Report
Public Property Name As String
Public Property SQL As String
Public Property Type As String
End Class
Then in the calling scope I want to have code that does something like:
' create my data context
Dim context As New MyAppEntities
' get a report object out of a dropdown list
[Code]....
So far I'm finding that .Net won't let me set the type in the (Of Type) clause on the fly at runtime.
Does anyone know how to do this?
I've tried changing the Type property of the Report class to an object of type Type, but that doesn't work either.
BTW, I know there are alternative ways to accomplish the same thing, but I'm working with external constraints that make this what I've got to work with right now.
So with the stock Textbox, I set the Scrollbars property to Vertical. This is great if the text in my box never changes; I can scroll up and down while the box sits still. If I'm running a background operation that logs output to the box though, the scrollbar resets itself to the top every time I append text to the box.
I know I can set the Textbox.Selection property (or use the Select method) to reposition the carat in the textbox, make note of that position in a variable, then append text, reset the carat, and use the ScrollToCarat method to reposition the scrollbar where it belongs. That's a really (ridiculously) long way around. Anybody know if there's another/better way of holding the scrollbar position, short of actually building a custom control (or using a Textbox and a separate Scrollbar)? It never hurts to try. In a worst case scenario, you'll learn from it.
I have a label the length of whose text can be changed by the user at runtime.I want it to be centred left/right whenever the text is changed.

With no answers from Google and not finding the answers by searching, just curious as you were to go about simply giving a ListBox a horizontal scroller once it passes its visible border the same as the vertical does?
