ASP.NET no, because the page is only HTML with javascript....
|
|
|
|
|
So that makes you ask in the VB.NET forum??
|
|
|
|
|
Because my code had two parts, the first is in vb.net and second is html/javascript.
I would appreciate that instead of questioning the place of the wire we can concentrate more on the problem ... Thanks.

Your problem has to do with JavaScript and ASP.NET, not VB.NET. Even after writing VB code for the last 13 years, I couldn't tell you what's wrong with it. It'll work perfectly in the Windows Forms application. I have no idea what mechanism JavaScript uses to communicate with your object.

1 - The Situation:
I'm Using "Visual Basic 6"
I'm Using "Webbrowser Control"
I'm Using "Microsoft HTML Object Library"
====================================================
2 - What I Want:
*Acees objects (buttons, links, etc) on a IFRAME
*Get all links for example, click in links, etc...
This is easy... but...
===================================================
3- THE PROBLEM:
The page A is in www.abc.com
The page B is in www.xyz.com
The Page A contains one iframe to page B
I Can't acess elements in Iframes with diferrent domains using normal methods.
====================================================
4 - Example:
PAGE A.html (www.abc.com/PageA.html) ==>
<html>
<body>
THIS IS THE PAGE A!<Br>
PAGE A contains one Iframe to PAGE B!<br>
<Iframe id="PageB" name="PageB" src="http://www.xyz.com/PageB.html">
</body>
</html>
====================================================
For example, if a try to get links of page B (iframe) pufff...
"{"Access Denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))"}"
====================================================
5 - The phrase for the more experienced are:
Nothing is impossible! you know!
How can I then perform this procedure?
Thanks
====================================================

Hmmm,
This looks like a distinct case of cross site scripting (XSS) security, and for security reason is probably being blocked by the browser (WebBrowser control)
Just a thought as I know nothing about XSS.

Probably!
But if you notice, some extensions like:
* IE Developer Toolbar (IE)
* Firebug (FF)
can access any element.
This shows what is possible.

I would suspect that is because they are browser plug-ins that can interface with all data the browser sees.
You are talking about a web page reading another web page DOM.
[editing now i have re-read your post again to undetstand the problem more!]
Can you read the source attribute of the iframe? if so why not read that directly and access the source data directly?

Hello friends,
I tried converting lower case char to upper case and vice versa
it works fine with the following code
Dim abc As String
Dim xyz As String = String.Empty
Dim a As Char
Console.WriteLine("Enter The String")
abc = Console.ReadLine()
For Each a In abc
Dim b As Char
If Asc(a) > 64 And Asc(a) < 91 Then
b = Chr(Asc(a) + 32)
ElseIf Asc(a) > 96 And Asc(a) < 123 Then
b = Chr(Asc(a) - 32)
End If
xyz = xyz + b
Next
Console.WriteLine(xyz)
Console.ReadLine()
case 1 Input : ABCdef
Output: abcDEF
case 2 Input :ABC def GHI
Output:abccDEFFFghi
Desired Output:abc DEF ghi
The issue is maintaining the whitespace between the strings, with the current code the the whitespaces are replaced by the previous charcter in the output.
I like the whitespaces between the strings to be maintained .
Thanks In Advance

What an ugly, ugly mess. Char.IsAlpha is what you need, from memory. And Char.ToLower.
How about abc = abc.ToLower()

End If
xyz = xyz + b
The core flaw in your logic is that you need another else.
else
b = a
Otherwise, anyting that is not a lower or uppercase character, is lost.
you look like you're coming from VB6, that's where all the nasty habits are coming from. Forget VB6, learn to use VB.NET properly. And, learn to use the debugger, if you stepped through this code, you'd have seen in no time what the issue was.

very simple...just add one 'Else'... as below...!
Dim abc As String
Dim xyz As String = String.Empty
Dim a As Char
Console.WriteLine("Enter The String")
abc = Console.ReadLine()
For Each a In abc
Dim b As Char
If Asc(a) > 64 And Asc(a) < 91 Then
b = Chr(Asc(a) + 32)
ElseIf Asc(a) > 96 And Asc(a) < 123 Then
b = Chr(Asc(a) - 32)
Else
b = a
End If
xyz = xyz + b
Next
Console.WriteLine(xyz)
Console.ReadLine()
Enjoy!

Dim ca As Char() = TextBox1.Text.ToCharArray
TextBox1.Text = ""
For Each c As String In ca
Select Case Char.IsUpper(c)
Case True
TextBox1Text &= c.ToLower
Case False
TextBox1.Text &= c.ToUpper
Case Else
TextBox1.Text &= c
End Select
Next
My advice is free, and you may get what you paid for.

replace this by Dim b As Char = a
the logic is: output char equals input char, except when it is an upper/lowercase letter.

What code can I use to read the column and row position of the blinking cursor-thing in a multiline textbox? I am trying to replicate the bottom right corner of windows notepad when you have status bar visible, by default it usually says: "Ln 0, Col 0"

I'm not sure you can do it directly. Use the Lines property and iterate through until you find the current line based on the current Selection. You might need to take into account the CRLF at the end of each line.

Yes i sort of see how that would work something like:
line = textbox.Text.IndexOf(vbCrlf).compareto 'something
column = textbox.Lines.Length '.something / something
not sure how to go about it though it does seem possible
|
|

|

err no, Lines gives you an array of all the liens in the control, something along the lines of:
position = textbox.SelectionStart
line = 0
while (position > textbox.Lines[line].Lenth
position = position - textbox.Lines[line].Lenth
line = line + 1
Loop
col = position
Note: this has not been tested.

Hey thanks that really helped.
column is still wrong though.
also when the textbox.SelectionStart is on the last line, it causes an out of range error, other than that it works great.

|

|

look at adding the extra characters for the end of line.

Hi,
i've made a control which is supposed to drop down on button click. it works perfect if i place it out of table layout, but if i drag drop it in a form with table layout panel... drop down doesnt show...
possibly because of control's parent? OR z-order?
any help will be appriciated....
thnx!
|
|
|
|

I believe that the control is bound to its own 'cell' in the TableLayoutPanel. To test that, why not try dropping in a ComboBox, and see if that works properly?

Yes sure! every other control works normal if dropped on the table except for the custom made one.
Question is... why doest it works well if dropped on a form ... but once you bring it inside a TableLayout... it does'nt!!
my control uses TextBox, Button and a CheckedListBox that is shown on button click... all these items are inside a TableLayout whose Dock is set to fill and rows are set to Autosize.
i've tried to '.BringToFront()' and things like that but no use...
if it is bound to its own cell as u say... what to do next??? re-design without TableLayOut?? ahh...headache!!
