I have windows application in which I have web browser control. I want to display vertical scrollbar, somehow its not getting displayed. Is there any way of enabling the scrollbar or any property which need to be set. I have already set the ScrollEnabled
View 7 RepliesSo 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.
My problem is that I built this program for my VB class, but I built it on my desktop at home which is a 23" monitor. When this is opened on a smaller screen, you dont get to see all of the project. I want to add a vertical scroll bar but that is beyond what I have been taught and beyond what my book teaches...
how to get a vertical scroll bar to scroll the whole form?
I have a TOS agreement that i would like my user to have to view ...
basically the same way "World Of Warcraft" does it ...
You must scroll to the bottom for the accept button to be enabled and clickable...
but in vb.net i cant seem to find a way to determine the vertical scrollbar postition .
The 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

View 2 RepliesI have a TextBox control with a lot of text which has a vertical scrollbar, and every time I hide/show the control the position of the scrollbar stays the same. I'm trying to figure out how to change the position of the scrollbar to the top of the textbox, as if it were at the beginning of the text.
View 1 RepliesI faced a problem that the vertical scrollbar of datagridview will be un-functional.Here are the steps to rebuild the problem:
1. Add a new datagridview component.
2. Add a new timer to set the datasource of datagridview at a regular time. For example, I add following code on the Timer1.Tick event:
Dim v_connDB As New Odbc.OdbcConnection
Dim v_daCA2 As New Odbc.OdbcDataAdapter
Dim v_dsCA2 As New Data.DataSet
[code]....
3. Then I press the down arraw key on the vertical scrollbar with mouse while the datagridview re-bind its datasource, the vertical scrollbar will be un-functional. And the action will be changed to be re-size the datagridview will I press the vertical scrollbar position.So, is it the bug of datagridview? How can I fix it?

View 1 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 9 RepliesI have a load of information on my label in a groupbox on the form there is too much information to be seen in one go so i want to use a vertical scrollbar to move the label up and down inside the groupbox so it can be read.
The issue i'm having is:
1: The label covers the bottom edge of the groupbox (looks a little naff) i need it to fall inside the groupbox if possible.
2: Any movement on the vertical scrollbar seems to send the label in one direction only - so how do i work it so that up moves it up and down moves it down?
Should i use a multiline textbox rather than a label and move the carat?
I need to set the background color of a label based on the value of a vertical scrollbar. i.e, if the user click the vScrollBar the background color of label must change like from 0 to 255.if it reaches to 255 again initialise to 0. I tried color.FromARGB function but it is not working.

I have been working on a much larger project and came to a point where I decided threading should be used.It seems in previous version of .Net, a background worker was able to update controls that were were not created on that thread. Now, it doesn't seem to be the case.I basically just began a new small project to try and teach myself the basics.Form1 Consists of A listbox, A progress bar, a label and two buttons, one to start and one to cancel.

pbprogress.minimum = 0[code=....
This code appears to be updating the listbox.I can see the vertical scrollbar getting smaller, but no data is shown in the listbox. The progressbar is also updating properly while that is working, indicating proper background operation.But what it's not doing is this:
1. Label is not updating percentage
2. The form is not free to be used by the user (me)

I'm working on a VB.NET application using VS2010 for an application that will run on a touch-screen. I have a problem with a mutli-line text boxes, ListBoxes and DataGridView controls which contains a vertical scroll bar. The scroll bar is too small for anyone with big fingers. Is there any way to make that scroll bar wider so that it's more "finger friendly"?
View 6 RepliesI'm using the following code to create a bitmap from a webbrowsercontrol that is located just off-screen (not visible to user, but control is "visible") Does the CopyFromScreen method work for something that is not ACTUALLY displayed on the screen?
I checked the values of p.X and p.Y at runtime and they are correct, but my "img" does not reflect the portion of the "Screen" i'm trying to capture.
Not sure what I'm doing wrong here, or if CopyFromScreen will still work if my control is outside of the bounds of the primaryscreen.

View 1 RepliesHow to get a value from JavaSc in website via webbrowsercontrol to textbox
View 2 RepliesI coded a very small website bot in C# using the default WebBrowser control. Actually almost everything is working the way it is supposed to work, yet I seem to have problems with the very last step of my automation.
The website was built using several iframes. This isn't much of a big deal as I simply access those frames and their elements using
webBrowser1.Document.Window.Frames[0].Document.GetElementById("element").InvokeMember("click");
This however does not work when the source of the IFRAME is being hosted on a different domain than the actual website. As I searched the internet for an answer to my problem I stumbled across an MSDN article mentioning this specific problem and they were referring to safety measures against cross site scripting which might be the reason for this error.
I couldn't really find a way of disabling this feature so I moved on and decided to recode everything to work with geckofx-12 instead of the default (IE based) web browser control, yet I ran into similar issues...
My question is: Is there any way I can bypass this annoying behaviour? I don't really care about security concerns or on whether geckofx or the default web browser control is being used, I would just like to programmatically access the elements of a site which is being hosted on a different domain without running into an UnauthorizedAccessException.

I am writing a Windows Form program to automatically download and store generated PDF reports from a web site using the WebBrowser Control. The web site uses Ajax to link an icon back to the source aspx file which then returns a PDF file.
The problem I have is that the WebBrowser control brings up the File Save As dialog box when the PDF file is returned and I can find no way of handling this to cature and save the returned file. I have found other examples of how to manage this using the Navagating event to validate the extension of the file that is being accessed (e.g. [URL] and, if not an HTM, file then use the HTTP Web control to directly download the file. Unfortunately this will not work as the call references a .aspx page.
