I have a VB.NET program that has a WebBrowser control on one of the forms. I need to have the program automatically access some data on a website, so I need to log in using the available Java interface.
The simplest way to do that seems to be to simply type in the WebBrowser; the Java code will automatically accept that into the correct text field. The program must remain unfocused while this is running, so SendKeys is not an option. Therefore, I'd like to use SendMessageA to tell the WebBrowser I'm typing in it. I've tried using KeyDown and KeyUp as follows (to send the keypress "0", in this case), but that isn't doing it.[code]...
How do I simulate mouse click on webbrowser control based on coordinates (x, y).Coordinates of the webbrowser control. I wanna click a specific location on the webbrowser.
My computer is set for lets say a 15 minute begore the screensaver and passwork have to be re-entered.Is there a way using VB to simulate a keypress or mouse movement if no key was pressed or mouse moved within the 15 minutes?
The VB6 codes makes use of an Array of textboxes and lots of the code manipulates the textboxes selecting the target textbox via the index. This is very good because a small amount of code can reference a large number of textboxes simply by changing the index. To do the same in dot net I'd need a load of code for each box or I'd need to create the boxes at runtime.
But.
I was reading somewhere that it's possible to kind of simulate similar behavior by creating a bunch of text boxes at design time with the usual names names like TextBox1, TextBox2 etc and then referring to them in code like this:-
As part of a program that I am composing, the user needs to enter a value by way of a NumericUpDown control on one particular form. Once this and other criteria have been evaluated, the program will then move to the next "step" of the program. If they use the spinner built into the NumericUpDown control, the event is fired on every change and that's all well and good, but if they double-click the value in the control then type the value in manually, it doesn't fire until the control no longer has focus. I can't depend that this might be the case however. Using the "KeyPress" event, I can in fact know when the control has focus and the user has typed but what I cannot seem to get it to do is to get the control to "read" these keystrokes as values until the control loses focus.
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
I was asked to create an application that has a custom control that acts as a button. I managed to do almost all the requirements except the one for the KeyPress event. The customer wants to click the "Alt + C (for example)" to trigger the button click event in this case for a Cancel button. I did the code and it works fine ONLY when that custom control has the focus on it. But when it loses it, it doesn't. I don't know how to make the form accepts that KeyPress and sends to the custom control. I tried to set the form's KeyPreview property of the form to Ture but it didn't work too.
By the way, I know that it would work by writing the code in the KeyPress of the form but that's not the requirement because the user control will be used as a standalone component for many projects.
I have a application written in C# using a usercontrol which inherites from control.
On this control i want to use a PS/2 barcode scanner. Get recieve the response i user control.KeyPress. Some some of the chars gets filtered mostly the double chars.
I working on a project that includes to call a certain type of method to each control, i have this code:
Private Sub txtBcNum1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtBcNum1.KeyPress If Char.IsDigit(e.KeyChar) Or e.KeyChar = Chr(8) Then
[Code]....
I have 15 textboxes( txtBcNum1,txtBcNum2,....,txtBcNum15 ), what's the best way to call this function inside KeyPress method on each textboxes with out manually adding it to KeyPress method?
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 have created an app to load an access database into a datagridview, which contains web urls. When button is clicked it webbrowser1 navigates to each url and each webpages document.inertext is put into textbox. This all work fine but after a while the webbrowser navigation becomes increasingly slower.
For Each RW As DataGridViewRow In Me.DataGridView1.SelectedRows '''''''''''#######cell values into strings ########'''''''''''''' If RW.Selected = True Then Dim domain As String
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?
I 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?
I working on a project that includes to call a certain type of method to each control, i have this
Private Sub txtBcNum1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtBcNum1.KeyPress
[Code]...
This code works like a charm if i want to allow only numbers and backspace on my textbox.Problem: I have 15 textboxes( txtBcNum1,txtBcNum2,....,txtBcNum15 ), what's the best way to call this function inside KeyPress method on each textboxes with out manually adding it to KeyPress method?
I have a webbrowser control, where I show images (bmp files, that the program creates), and I want to add some UserControls to setup the images (as showing layers, or choosing colors to display). Is easy to do appropiate UserControls on VB.NET, and I know almost nothing about HTML, so, I would like to add standard VB.NET UserControls near the images.
I'm tried to make my own web browser by using WebBrowser control in VB.NET 2010. When I run my program it is work fine but when I try to open any link in new window it is opened in Internet Explorer. So how can I start new window in my web browser?
I am writing a VB.Net WPF application that needs to display HTML content and websites. I am doing this using the webBrowser control. The application takes a significant performance hit running under x86 and I would really like to keep it set to Any-CPU. However the webBrowser controls need to be 32bit so they can run flash. So is there any way of achieving this? Running the 32-bit webBrowser in a 64bit process, or some alternative control that will manage this and allow me to load HTML from a string and a URL?
Now, for this particular project, I have to use the Webbrowser control in VB. I normally wouldn't, But I need to display some modified HTML. So here is my problem.
Dim htmlorig As String Status.Text = "Loading: " & TextBox1.Text web.Navigate(TextBox1.Text)
[Code]....
The Msgbox comes up as soon as you click the button and is empty, No page source.
I'm having an issue loading one of our work websites in a WebBrowser control. In IE, it works fine, but in the wb control, it does not seem to process correctly.There is a frame, "mainframe" which when you click "result", goes back to the "to do list". However, i get a blank page in the frame, and then when i hit refresh, it comes up with a scripted error "Page Already Sent" which i'm not sure what it is triggered by.The pages are JSP pages, and i don't know if that might have some effect, but i'm more confused as to why they would work perfectly in IE, and then not work in WebBrowser control.
I'm running a webbrowser control with a custom user agent.when I try to load google with it, there are a number of 'script errors' in the website, which I've hidden by setting 'Scripterrorssupressed' to true. Now however there is still an 'object error' which pops up when i try to load google.Every other website that I've tried loads fine, and when I click 'ok' google runs fine. I'm quite sure its something to do with google 'location services' trying to locate my browser, because it thinks its a cellphone (due to the custom user agent).
Code: Public Class Form1 Dim m As String() Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click m = TextBox1.Text.Split(Environment.NewLine)
[code]....
it navigates only to the last website [URL] i think that's because the for loop is faster that navigation process?
I've downloaded and installed the control from here, but I can't get it to work! I've added the component so it appears in my toolbox, but when i try to draw it on a form it isn't visible. It size can't be changed from 0,0 or anything! I can't see a 'URL' section in its properties either, why is that?
