After 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.
Point mouseDownPoint; Point mouseUpPoint; Point mouseDragPoint;[code]......
I've got some server apps that I've been trying to get some metrics from so I can debug them. I found that when scrolling back up the window I'd suddenly get timeouts from the clients. Sure enough, moving the scrollbar stopped the application.
I'm probably missing something fundemental here, but I can't work out why moving the scrollbar on a Console window would block the thread. It's very simple to reproduce:
Sub Main() Do Console.WriteLine(Now.ToString("O"))
[code]....
Run that up, and any interaction with the window blocks the thread. In the example below, I just moved the scrollbar a bit and held it in position for a few seconds before releasing [URL]I've tried it with a Timer type loop rather than a Thread.Sleep but the same issue appears. What am I doing wrong (other than not using a service instead!)?
I want to make a panel scroll horotzional with a scrollbar. The panel will have images only (Maybe a label under each picturebox), and I don't have enough space for all the images, so I want to make it scroll horotzional.
When a panel's AutoScroll is set True then it will add scrollbars for navigation of the entire size of its content. What I want is to be able to set the vertical scrollbar to go to top or zero so its contents top controls will be viewable.
Im making a web browser (well I only want one page) but I want to stop the highlight scrolling, I've stopped the scrollbars and scrolling with the space key but highlighting still works. I did a bit of research and one said to put a transparent image over the top, but when I put a transparent background It turns grey so I can't even see the web browser.
I'm trying to allow scrolling in a Multiline-TextBox even if the TextBox is set to
textbox.Enabled = False
This is not possible, as the Scrollbar is disabled with the Enabled-Command, too.The default solution here is to set
textbox.ReadOnly = True textbox.Enabled = True
but this doesn't really do the trick for me. With ReadOnly I can still select the text of a TextBox as well as place the cursor inside of it. But as I have normal (non Multiline-TextBoxes) and other controls on the same form I don't want that to happen. I want to have exactly the same behavior as all the other disabled TextBoxes.
For everything else, like mimic the color of a disabled textbox and so on, there is a legitimate workaround with the ReadOnly-Property, but I coudn't find any for selecting text and placing the cursor.
UPDATE:I tried to use WIN32 API but it didn't work as expected:
Imports System.Windows.Forms Imports System.Runtime.InteropServices Public Class TestTextBox
I'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.
In a project I'm working on studying Regular Expressions in matching text in a text box to the regular ezpression. The indexes and lengths of matches in a text box are stored in a list box. When I click an index, I use the info to set the text box selection Start and Selection Length so I can quickly observe all of the matches in the text box by clicking or using the arrow keys to scan through the text box listings.
It works great except when large amounts of text are in the text box, some of the matches are scrolled off the visible area of the text box so it is necessary to manuall scroll throught the text box, which reduces the usefulness of the setup.Is there a way to get the text box to automatically scroll into hidden text that is marked with the selectstart and selectlength so they are all automattically displayed when the list box is clicked?
I am navigating to a website using a webbrowers control and I wish to automatically scroll the page after it is loaded. I have used scrolltop , scrollleft commands as set out below but nothing seems to happen. WebBrowser1.Document.Body.ScrollTop = 100 WebBrowser1.Document.Body.ScrollLeft = 200
I have placed the above commands in a command button and wait until the page has loaded before I press it and also in the WebBrowser1_DocumentCompleted sub
Other commands such as WebBrowser1.Document.Body.ScrollIntoView(True) Seem to work ok.
I'm making a program that updates a ListView filled with processes every second. After updating, it scrolls back up to the top. How do I stop it from doing that?

I have template designer form with scroll bar and maximized mode in MID form. Now, when I click on any of the item of ListBox placed at the the middle of the form, form automatically scrolls to the selected item. Is there any way to prevent auto scrolling?
I have set a scrollable control's autoscroll to true. What do you do when you don't want a scroll to occur? For example, suppose you have a RichTextBox and a button side by side as below: Notice that "button1" has the focus. If you click on the RichTextBox to give it focus, the scroll bars will scroll until the upper left corner of the RichTextBox is in view. But what if, for whatever reason, you wanted to keep button1 in view? How would you do that?
What would be the best and easiest way to change background image in a VB application from images that are preselected by user from any given folder on the hard disk.
So say "Mike" selects some images in D:ImagesNature in the Nature folder we have lets say "20" images. Now the VB app reads this and saves path so next time its open its fetching images from that folder once more. And every few sec lets say 45 sec a new image is loaded for background.
I need to limit a Textbox and DataGridView to only enter text in the fixed size of the cell/textbox on the screen. So I have limited the cell/textbox so user can not change it size. Both allow multiline and wordwrap. cell/textbox is sized to accept 5 lines of data (wordwrap or enters) This is like an online form.So the text enter will be printed so I can not allow scrolling in the cell/textbox.
How can I stop the scrolling of the text inside the cell/textbox.
Also : if the user Paste into the cell/textbox how to truncate text if larger than display area.
I am using datarepeater to display rows of information from database. When i click a 'save' button and i would like to loop through the rows of data in repeater. The code i am using is able to do all these. The only problem i encountered is at the Interface side. When i am looping the data-repeater. The selection 'frame' (refer to the picture point as 'A') is moving from record to the next record and scrollbar is auto moving as well to scroll to further down until the last row where looping finish.Is there anything can be done to remove the selection 'frame' and stop datarepeater from scrolling while looping the datarepeater.
I achieve to record and stop recording (manually with a button).
Now i want somehow to automatically stop recording after some seconds.
I used the following methods which did not work:
1. Used a timer to call the stoprecording function (I found out that while recording the timer did not work) I tested it with an msgbox and i was right, the msg box appeared 5 secs after pressing the stoprecording button!!!!
2. Used the System.Timers.Timer but nothing
3. I tried the CAPTUREPARMS structure but i`m doing something wrong and it doesn`t record.
Here`s my initialization:
Dim MyParams As New CAPTUREPARMS With MyParams .dwRequestMicroSecPerFrame = 66667
Just moved from VB.NET to C#.In VB to connect and Event Handler to a Sub we use the Handles clause.From what it seems, this do not exist in C#. After creating a simple application with a button I realize that Window Forms Designer automatically created an EventHandler to my button1_Click function (after I double clicked it), in Form1.Designer.cs with this code:
this.button1.Click += new System.EventHandler(this.button1_Click);
But, in VB, the WinForms Designer create the Handles clause in my class, in the function header. So, C# create the default EventHandler in designer file, while VB creates in main class where control resides.
I have found a few examples of this. basically instead of it watching only one folder, how would I have it watch any folder that's not named system32? I know I would need something similar to this:
I have a custom UserControl that contains just one TextBox. When I set the control to Enabled = False, the TextBox is disabled but the control is not (control still fires the Enter event).
How do I ensure that the UserControl will not receive focus?My Enabled Property Looks like this:
Private _Enabled As Boolean = True Public Shadows Property Enabled As Boolean Get Return _Enabled End Get
I currently have a working program that creates one colored pixel in a Bitmap, displays the bitmap in a pictureBox, and "jiggles" the pixel by making it move in a random direction by 1 pixel every time a button is clicked. I want to make the pixel move automatically until a Stop button is pressed.
am working with Web Browser control and with emails ".eml" ,simply am just navigating the WeBBrowser to the email object in my computer and is displaying my email body
but if the email has attachment picture(NOT AN EMBEDDED PICTURE) then the Browser automatically display that image to the center of the browser for example the last line of the html code is <CENTER><IMG SRC="CID:{A4BE96B0-6195-4D93- 45E-97D4B1CA3539}/nature2.jpg"></CENTER> but actually the email dose not has this picture as embedded but is only an attachment ,and the browser is displaying it.
is there any way which i can easily disable that functionality or i should modified the code and replace that string with nothing. ?
Im trying to fill a listview(tiles) with posters and titles of a DVD collection but only the titles become vissible.
this is my code:
Private Sub fillListView(ByVal listView As System.Windows.Forms.ListView, ByVal col As Collection) listView.Items.Clear() myImageList = New ImageList() For Each item As bsDVD In col
My app has scrolling images in the background and a picturebox on top. The image in the picturebox has transparent parts. How can It so that the transparent parts show whatever is belo the picture box, not the form background? I have tried taking screenshots and positioning them as background but this just freezes the app.
Dim ScreenSize As Size = New Size(154, 83) Dim screenGrab As New Bitmap(154, 83) Dim blank As New Bitmap(100, 300)
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.
