View 2 RepliesI have a weird problem (probably only to understand) why in a test app the focus rect is not shown until I press the tab key. I want to show a dialog with two radioboxes and two buttons. When I display the dialog, I'd like to see a focus rect around my first radiobutton. (So that the user can see where the focus is.) I ordered the controls and set the tabindex property from 0 to 4 so that they are in the correct order. (radiobox 1 has tabindex 0, ...). When I show the dialog the first radiobox has the focus, but it has no focus rect around it. (Until I press tab key.) I created an completely empty winforms project (Visual Studio 2010), added the controls and started it. So there is nothing special at all.
Here is the code of my sample:
Public Class Form1
Private Sub Button1_Click(sender As System.Object, _
e As System.EventArgs) _
Handles Button1.Click
Me.Close()

I have another question.I have taken an HTML file called "template.html" and got its content. Then I change some variables and save it to a new file in the same directory. Afterwards, there is something else I need to do before saving but I don't know how.In the template.html file, I have a table which should represent a table from a SQL database which means I would need to loop it. But I don't know how to loop that.

I want to read the HTML from a frame in a web page. I have started with a WebBrowser, which I browse through manually, attempting to scrape the details as I go. The reasn for using Web Browser is that it involves a complex form, which I can't really replicate in code.If I directly query the WebBrowser info I get very little, and the frame data id represented simply by a FRAME TAG, and a simple URI with no form data (it needs the data to return the content)I tried the Web Browser documentStream, and again I get very little.The closest I got to the full HTML is the following code. However it is missing the OBJECT tag and it's contents, which is what I absolutely need:
htmlwin = wb.Document.Window
For Each frame As HtmlWindow In htmlwin.Frames
For Each el In frame.Document.All

View 1 RepliesWebBrowser Example.zip IntroductionBecause the WebBrowser control that we use in .NET is a COM control, not all of its uses are straightforward and some of them (even those which seem like they should be easy) require that we dip into our Interop toolbox in order to properly implement them.
A perfect example of this is loading HTML content into the WebBrowser from memory, rather than a file or a URL. Anyone who's ever used the WebBrowser control before is familiar with the Navigate2 method, which tells the control to load content from a URL (or path to a file). Loading HTML content from memory, however, is a rather elusive practice because of the many steps involved in making it work.
MSHTML.HTMLDocumentYou might notice that the WebBrowser control exposes a "document" property. The object returned by this property can be coerced to the type of "mshtml.HTMLDocument" (you must add a reference to MSHTML to your project in order to make this work) as follows:
Code:Dim clsDocument As mshtml.HTMLDocument = CType(WebBrowser.Document, mshtml.HTMLDocument)
(NOTE: You will have to add a reference to the COM library MSHTML to your project to make this compile)
Once we create an instance of HTMLDocument, a whole new world opens up to us, providing all sorts of DOM access to the content of any given Web page.
If we were to create our own HTMLDocument object from memory, we could use the "write" method to write HTML content to the document from a string variable, like this:
Code:'initialize the document object within the HTMLDocument class... clsDocument.close() clsDocument.open("about:blank")
'write the HTML to the document using the MSHTML "write" method... Dim clsHTML() As Object = {sHTML} m_clsDocument.write(clsHTML) clsHTML= Nothing
WebBrowser Control ImplementationUsing the HTMLDocument returned by the "document" property of the WebBrowser control, however, is not as straight-forward. Because of the way that this object is created and initialized in memory (by the COM WebBrowser control), the "write" method fails when called as above. In order to write content to the HTMLDocument exposed by the WebBrowser control, we must first marshal the string value to a memory space that is compatible with COM. Once the string is properly marshalled, the COM interface IPersistStreamInit (implemented by the HTMLDocument class) must be used to pass the value into the object.
Interop DeclarationsIn order to pull all of this off, we must declare several Interop pieces, including an enumeration, a function, and two interfaces. The declarations for these pieces are as follows:
[Code]....
I'm writing a small program that loads a folders contained file names into a list box, you then double click one of the file names listed and it appears within the programs text area where the user may freely edit it. I then have given the users options to export the data contained within the text box to a word template. What I'd like to do is add a button which the user can click in order to strip away all the html within the text areas content. I found a solution but for some reason I can't make it work. There are no errors displaying nor does the program crash out, it simply isn't doing what it should be doing.
The function I'm using is below:
Function stripHTML(ByVal strHTML)
'Strips the HTML tags from strHTML using split and join
'Ensure that strHTML contains something
If len(strHTML) = 0 Then
stripHTML = strHTML
[Code] .....
I've used the below snippet in an attempt to put the function to work in the text box.
Private Sub btnHTMLstrip_click()
' calls function stripHTML, applies to text box
richTxtBox.Text = stripHTML(richTxtBox.Text)
End Sub
So, its not working as it should?
When a Windows Forms TextBox control first receives the focus the cursor has to be there at first position in the Textbox.
We have tried to resolve the above issue by adding below code in form load event.
TextBox1.SelectionStart = 0
TextBox1.SelectionLength = 0
Now, when a Windows Forms TextBox control first receives the focus, the default insertion (cursor) within the text box is to the left of any existing text. The user can move the insertion point with the keyboard or the mouse. If the text box loses and then regains the focus, the insertion point will be wherever the user last placed it.
But the problem is when some operation is performed in TextBox_Leave event, it will loose the focus. Again when it receives the focus, the whole text is getting selected instead of showing cursor where the user left.
I need the text within a textbox to be selected when the user clicks in via the mouse, if the user uses the Tab key the text is selected. I have tried Handlers .Enter / .GotFocus / .MouseClick / .MouseUp with textbox1.SelectAll() but it doesn't select the text.

I have a numeric updown. And I was looking for a way to select the numbers when a user gets focus. I know how to do this for a textbox, but there is no SelectionStart/SelectionLength expression.
