I am creating an user interface for a touch screen in visual basic. The application displays files in the web browser control. But unfortunately the touch screen accepts every touch as double click. Hence the user can not use the scroll bar for scrolling. Is there any way to make scrolling a button event?
View 3 RepliesMy listbox has 19 lines, Is there a way to scroll down and show line 20-39 when I click a button? My application is designed for a touch screen so it is impracticle to use the scrollbar.
View 2 RepliesI am currently working on a web browser using visual basic and i think i am stuck at this point where i have a panel and i need to scroll it when mouse hovers a button .. actually if i can find how to scroll the panel without using the scroll bar , i think i can modify it for using it with mouse hover.
View 3 RepliesAfter scouring the articles online I have come up with this design for a winforms based touchscreen app that needs smartphone like scrolling. The app itself will run on a tablet laptop or touchscreen desktop.I put everything I want to scroll on a panel. Set autoscroll to true (which will show scrollbars)Now put this whole panel inside a groupbox.Shrink the groupbox until the scrollbars are hidden (visually hidden, not visible = false)
Now the fun part I am stuck at.I think I have to handle the mousedown, mouseup & mousemove on the panel to set the autoscrollposition so that when someone touches the panel and drags, it does it's scroll magic. Please help fill in the few lines of code in below method stubs. The msdn doc on autoscrollposition is very confusing since it returns negative numbers but needs to be set to positive with abs and what not.

View 1 RepliesI believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.

View 5 RepliesI have a silverlight page with a textblock and button on it. Like this:
<TextBlock x:Name="txbNote" Margin="50,50" Text="Hello"/>
<Button x:Name="btnCheck" Height="40" Click="btnCheck_Click" ClickMode="Press" Margin="50,50,50,50" Content="Check Service"/>
Here is the handler for the click event:
Private Sub btnCheck_Click(ByVal sender As Object, ByVal e As EventArgs) 'Handles btnCheck.Click
txbNote.Text = "I Was Clicked"
End Sub
[Code]...
The only change is the relative position of the textblock and button. The button's click event (and every other event I tried) just doesn't fire unless the textblock is before the button in the xaml.
rticularly when creating jQuery buttons with no text and just icons) as a result of this.Secondly I am attempting to create my own custom button output by overriding the Render() event and am having a bit of difficulty trying to understand how to go about changing the output that is provided by this event.If I look at the HtmlTextWriter that is provided as the parameter to the Render() event I can see it contains a protected property TagKey = Input {47}, is it possible to simply modify this property somehow and change it to a Button or do I need to create a new instance of the HtmlTextWriter and populate it all from the start? If so, could anyone provide some guidance as to how this would typically be done and if there are any special considerations I need to make to ensure that my derived button class is functionally equivalent to the original (excluding the html)?

Im trying to create a webform that is a representation of a paper questionnaire that has 14 questions with yes/no answers. If an answer is no, then you must provide information as to why in 3 separate textboxes and store the information only when a user clicks no.I also have 4 drop down lists that are chosen before the user answers the first question that also need to be stored with the textboxes, but the ddl's value does not change after the user starts. Right now I have 3 textboxes and a submit button for each of the 14 questions that are hidden until a user hits a "no" button, in which I change the visible property of all of them and the user then types in their reasons and submits the answer. I am currently doing this for each question and i hide/disable the textboxes and button after submitted.
My problem is that for each event on the 14 submit button's is that I'm forced to open & close an sql connection and insert the values. I know there has to be a way to simply this some so that I dont have 14 different groups of the same code. I would also like a way to eliminate having 40 textboxes on a page lol, because the idea was to have a pop up box or something open that would let the user submit it and then return to the question instead of hiding textboxes, but the user has to see all 14 questions at page load so if you got an answer to that one then that might solve my original question.

I have a system with 26 buttons but the buttons actaully run the same code; aside from the fact that the index number is used to distinguish between them (es, I know index values are out so I am using the object's name (btnKey1, btnKey2, etc).
Is there any event that occurs for all button presses or do I need to write the same line for all 26 events (actually 52 since I am using MouseDown and MouseUp - will get worse when I want to use the keypress side)?
