I am trying to make key shortcuts (e.g.: control + c = copy) in my program, but it seems to work in everything BUT the webbrowser control. I have keypreview set to TRUE, and have the code "for each control.... addhandler....form1.keydown" (you get the point).

View 4 RepliesIn my old VB6 programs I use control events like Keydown to activate code. The code is the same for all text controls. However, I am hoping that there is a efficient way of handing this in VB.net. Using VB2010.
Private Sub txtField1_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtField1.KeyDown
ButtonState2()
End Sub
Private Sub txtField2_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtField2.KeyDown

I have a TextBox which Is allowed only to read certain characters. I use KeyPress event to handle this event. I understand that The KeyPress event does not handle the pressing of the DELETE key on the keyboard. I do not want the user to be able to delete characters in the txtbox by using the DELETE key, I want the user only to be able to use the backspace key. I am writing this code in Visual Basic 2005. The following code appears to work in handling the DELETE key, but I am concerned that I might get bitten by the fact that I am using KeyDown and KeyPress on the same control (txtSource).
private sub txtSource_KeyDown(byval sender as object, byval e as KeyEventArgs) handles txtSource.KeyDown
IF e.KeyData = System.Windows.Forms.Keys.Delete then
e.handled=true
end if
end sub

For some reason the application is not closing... IS there something wrong with this code that I am not seeing?
In the application I'm working on I use F1 and also a right mouse click to close the application since the graphics display full screen and there's no control in the upper right corner to close with. I use a good number of different keypresses to control things and everything works fine. When I switch away from the form that the applications starts in to a different form I'm not getting any response from either a KeyDown or a KeyPress event. Maybe someone knows what's going on. The ButtonClick and MouseDown events are responding just fine but for some reason the KeyDown and KeyPress events aren't. Below is code for one of the Forms that is unresponsive in this way.

View 4 RepliesI am trying to catch key board events with the form keydown.
I am able to capture all the keydown events except the "Enter" key. When the enter key is pressed this code does not even fire.

Select Case e.KeyCode
[Code].....
I try to catch the keydown event, but arrow keys don't fire this event, although I set KeyPreview = True. Arrow keys neither fire the KeyUp event. Not on the form or on any controls..
What is required to handle:
1. Arrow keydown or keyUp event with individual event handler based on mouse focus/hover (does the control have focus if mouse hovers on it, or it needs to be clicked?)
2. Mouse scroll events individually based on "mouse focus"
I don't actually need for the form... Since all the form is covered by controls.. But I need individually for different controls. Which are just buttons, labels and a chart control.
Looked up a number of pages on KeyDown, and KeyPress events, and am just more confused than when I started. I am trying to get an event to fire adding value to a total when a user presses the Enter key. Not getting any compiler errors, and have tried utilizina MSDN's suggestions for IsInput, and PreviewKeydown. None are working..... I have tried working in the KeyDown using e.keyCode = Keys.Enter, and KeyPress using e.keyChar.Equals(Keys.Enter) in my conditionals.

View 11 RepliesI am trying to use the keydown/keyup events with buttons in the same project and it not working properly. I have 4 red boxes and when I press an arrow key the box should change to green according to which arrow key it corrosponds to. I have this part working fine, however only when there is nothing else in the project. When I add in say 3 buttons, Button1, Button2, Button3 and try runing the program instead of the correct red box changing to green, button outline just moves between buttons 1,2 and 3. I have tried turning tabstop off for the three buttons but that didnt work. how to read the keydown/keyup while still having buttions that can be pressed with a mouse?
View 4 RepliesI created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at.

View 2 RepliesI'm using a webBrowser control as a simple HTML editor & I'm trying to stop the default action of creating a new <p> (paragraph) element every time you hit the enter key while typing text into the control.
I have added a handler for the keyDown event & I can insert a break tag, but nothing I do seems to be able to stop the webBrowser from continuing to process the event.
As you can see in the code I tried setting the e.BubbleEvent to false to stop the event.
The added event handler works just fine & executes before the webBrowser processes the event, but setting the e.BubbleEvent=False (or true) has no effect.[code]...
The form registers it fine, but if you click anywhere on the web browser, it does not.
I want to refrain from injecting Javascript to make it work.
I have KeyPreview enabled.
All of the below do not register as a click on the webbrowser:
Private Sub WebBrowser1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Click
MsgBox("Hello")

I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.

I am writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.

I'm writing a tabbed web browser for someone who is learning VB.NET, and I have got to the point where I can add/remove browser controls into tab pages, controlled by one set of buttons on the main form, but I can't handle events from the WebBrowser objects.I have tried this but it says that 'DocumentTitleChanged' isnt an event of 'Control'...
Dim browser As New ArrayList
browser.Add(New WebBrowser)
browser(0).parent = TabControl1.SelectedTab
browser(0).dock = DockStyle.Fill
AddHandler browser(0).DocumentTitleChanged, TitleChangedHandler()
I want to update the tab title with the web page title when it changes. I started using a timer to update the tabs but there must be a way to add an event handler here.
Ive tried to edit option on the webbrowser control, example javascript enable/disable. but found out that it uses IE's option and cannot be changed.So my question is: Is there a way to do a "webbrowser" without using the WEbbrowser control that is based on internetexplorer? If it is, can i change option example flash and so on?
View 6 RepliesI have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?
