GetScrollInfo Does Not Return Correct Status Of Scrollbar
Sep 10, 2009
I have created a small subroutine that resizes controls which don't have an autosize. The idea is to use the scrollbars to see if the content fits into the control. Whenever I want to autosize the hight of the control I call the getScrollInfo with SIF_POS.
Making the control "higher":
If nPos is then > 0
I add some pixels to the size.heigt of the control until nPos is =0
This is working fine.... One small problem: When I "switch" of the scrollbar for that control after I reached the right size and then switch it on as soon as I get into my routine again... my routine doesn't work anymore. [Code]

Expected Results: A scalar result of the comparison between Array1 and Array2 such that when Array1>Array2 it is true. See expected array above.
Actual Results: When Result(x) is true, all elements become Array1(x) and Array2(x) .What is wrong with the function?

I'm using Windows 7 and I built a small application that just moves the scrollbar of the current active window to some value.The problem is that nothing happens. I tried using GetScrollInfo too but I only got 0 in the nPos parameter.
This is my declartions and constants:
Private Declare Function GetForegroundWindow Lib "user32" Alias "GetForegroundWindow" () As IntPtr
Private Declare Auto Function SetScrollInfo Lib "user32" (ByVal hWnd As IntPtr, ByVal fnBar As ScrollBarDirection, ByRef lpsi As SCROLLINFO, ByVal bRepaint As Boolean) As Integer
[code]....
On the form load I just do a delay of 2000 milliseconds so I could focus on another window, wait and nothing happens.
System.Threading.Thread.Sleep(2000)
My.Application.DoEvents()
ScrollCurrentWindow()

I've created a log in system using a database and query builder to return the correct values, however, once the users signed in I need to bring up the rest of their data from the same table in the database. How'd be the best way of going about this? I'm not sure whether the log in should be changed to use the primary key as well.

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 created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)

I'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works. I get no errors, but the returned value is always NOTHING, instead of an object.
I've worked up the smallest sample code I could, and have included it below. Essentially, just call RPtest and single step through. The code creates a simple object, RPTestA, with a string field and an object valued field It then retrieves the string

How can I make a textbox have a scrollbar that appears when the text goes off the screen so the user can scroll down as needed?

I have inherited support for a program written in VB2008
The problem I have is as follows:
Users have a low screen resolution (company policy) and so can't see the bottom of a particular form.
The bottom of the form has buttons that allow them to navigate between its' four pages so they need to be able to see them. This being the case I need to add a scrollbar to the form.
If I try to drag and drop a vscrollbar from the toolbox it just sits there at runtime (you can slide the button on the toolbar up and down but nothing happens regarding scrolling the page.
All the reading I have done seems to point to forms being given scrollbars in accordance to the AutoScroll, AutoScrollMargin and AutoscrollMinSize properties of the Form itself.
By setting these properties I can get scrollbars to appear in the IDE but they are not there at runtime.
I think I'm probably missing something really obvious here but, so far, have been unable to work out what it is.

So, in my vertical scrollbar, the maximum value is 16. In my application, I made a Label to track the scrollbar's value, just for testing purposes. I noticed that when I move the bar to the bottom, the value is 6. And when a [i]release[/i] the button (stop holding it with the mouse), the value becomes 7. Something similar goes when I move the button to the top: It is 1, and when I release the button, it becomes 0. That's a bit weird, but what mainly bugs me is why I cannot reach value 16?

I'm working on a project which must run on several computers, each with their own version of windows.
In Windows XP the project runs fine, but in Windows 7 I get a horizontal aswell a vertical scrollbar. I can't seem to turn it of.
I'm using a MDI parent and several childforms, eacht childform neatly adjusted in size to fit the parent, not exeeding the parent limits.
autoscroll is false
windowstate normal
Am I missing something, or is this just a supurb item in wondows 7?

I create some vscrollbars dynamically and add scroll event handlers to them. I really want to detect when the user has finished scrolling with a mouse up event but this doesn't seem to be part of the scrollbar events.

I'm trying to make a user control similar to the Windows Vista/7 breadcrumb bar used in windows explorer. However, when I show the drop down menu for a breadcrumb with many sub items, I get a very long list that sometimes exceeds the screen size. In the Windows Vista/7 example however, there are a maximum of 18 items displayed at a time and a scrollbar appears at the right when the number of sub items exceeds this number (18).

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.

I have a form with multiple richtextboxes that have synchronized scrolling (ie when one RTB scrolls, the other RTBs scroll down with it). The only problem I have is that I have 10 RTBs, which means 10 scrollbars in total. I would like some of them to not show for simplicity reasons. Basicly the scrollbar of RTB1 to show and hide the rest.

I have a game with a large panel in VBE2008 with a Vertical Scroll Bar Control.
The user uses his mouse to move it up and down, etc.
But how can the game program move this control?
For example, the control bar is slid down to the panel and I want my program to slide back to the top starting position when the user clicks on the Reset Button.
