Hello,
Currently I am automating website in Internet Explorer. Due to compatible issue in different IE's, I am planning to automate in Google Chrome.
I have searched on internet for that, many have suggested that Selenium is the best solution. But in selenium I will get events only if events are created using code. If user manually navigate to some other URL then we cannot manage it.
Mainly I want the same working as there in Internet Explorer. For example, 'browser control', 'beforenavigate' , 'documentcomplete' etc.
What is the best working method to website automation in Google Chrome using C# ( With all functions which can be done in Internet Explorer)?
Please help.

Currently I am having vb6 project for Website automation in Internet Explorer. So I thought It would be better if I migrate to vb.net or C#.

There is nothing I can see in your question realated to either VB.NET or C#, which is why I suggested the Web development forum.

Hello friends,
I'm working on a keyboard application for a small community. Their alphabets are as shown below.
Basically, the application will allow users to either type on the pc keyboard, or the virtual onScreen keys.
It should be noted that their alphabet do not have letter Q, F, X, Z and this will be replaced with Unicode chars.
I've managed to get the onScreen working using the SendKeys.send() method of C#.
However, I'm having trouble getting this working with keyboard input using KeyDown method.
When someone type Q, I wanted Unicode character say "Ɣ" to appear, and not the letter "Q".
A partial part of my code is as below. The keyDown event doesn't seem to fire at all.
Appreciate any help please.

As I recall, the KeyDown event is sent to the control which currently has the keyboard focus. That is quite likely not your form. You may need to attach your handler to the KeyDown events of multiple controls to achieve your aim, or otherwise ensure that focus is on the control you choose.

Peter, thanks so much for your response.
That seems to be my problem at the moment.
How do I do that please?
Thanks,

Try setting the Form.KeyPreview property to true - if you don't, then the other controls get "first dibs" on the keyboard data.
If that doesn't work, then override the Form ProcessCmdKey method - you should be able to detect it there.

Hey buddy! Thanks.
Here is what I have tried. It's not working though except that it sends Ö and close the program. However, when I comment out this.Close(), the program does not put the above character on ms word. Is there anything I'm not doing right? I intent to use switch & cases if I can get it working this way.
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == Keys.Escape)
{
this.Close();
SendKeys.Send("Ö");
return true;
}
else
{
return base.ProcessCmdKey(ref msg, keyData);
}
}

You aren't sending anything to Word - you are sending it to your application...

Hello OriginalGriff,
My intention is to send something to applications such as word, notepad etc. etc.
In my code, i have the SendKeys.Send() to send out relevant to the above applications. I'm not sure if it's right in this case, but it works for sending characters when buttons are clicked.
Here below are the main methods. What should I really do here? How should I send it to the Ms Word please?
protected override CreateParams CreateParams
{
get
{
CreateParams param = base.CreateParams;
param.ExStyle |=0x08000000;
return param;
}
}
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
switch (keyData)
{
case Keys.Q:
SendKeys.Send("Ɣ");
break;
}
return base.ProcessCmdKey(ref msg, keyData);
}

SendKeys sends to the active application - which if your app is receiving the keyboard input is your app, not Word or Notepad.
Providing an onscreen keyboard that "interfaces" between the user and any other app is a much more complex job - and not one I have any experience with. I suspect that you will need to look at Global Hooking to "preview" the keyboard and intercept things, which is not a job for the faint hearted (get it slightly wrong, and your dev system will become very unstable).
I'd be tempted to look at "custom" keyboard layouts instead of hooking: The Microsoft Keyboard Layout Creator[^]

Hi, I finally got something working with keyboard Hooks. However, now both unicode character and the key value of the pressed are being sent. For example, when I pressed Q, I expect to see Ɣ on word, notepad etc. However, I'm getting both i.e. QƔ at the moment. How should I remove the Q and display only the sent character?
private void Form1_Load(object sender, EventArgs e)
{
ghook = new GlobalKeyboardHook();
ghook.KeyDown +=new KeyEventHandler(ghook_KeyDown);
foreach (Keys key in Enum.GetValues(typeof(Keys)))
ghook.HookedKeys.Add(key);
ghook.hook();
}
private void ghook_KeyDown(object sender, KeyEventArgs e)
{
textBox1.Text += ((char)e.KeyValue).ToString();
processKeyPressed((char)(e.KeyCode));
if((char)(e.KeyCode)=='Q')
SendKeys.Send("Ɣ");
}

I thank you for your response, Original.
I wish we could get this working.
Still believe someone out there would help.
Thanks.

So I basically have a Complex Matrix class like so:
public struct ComplexMatrix
{
private int Rows;
private int Cols;
private Complex[,] matrix;
public ComplexMatrix(int Rows, int Cols)
{
this.Rows = Rows;
this.Cols = Cols;
Complex[,] temp = new Complex[Rows, Cols];
this.matrix = temp;
for (int i = 0; i <= Rows - 1; i++)
{
for (int j = 0; j <= Cols - 1; j++)
{
matrix[i, j] = new Complex(0, 0);
}
}
}
public Complex this[int Row, int Col]
{
get { return matrix[Row, Col]; }
set { matrix[Row, Col] = value;}
}
...
However, Im a bit lazy so I would really like to set matrix items as follows:
MyMatrix[1, 1] = new Complex(1, 0);
MyMatrix[0, 1] = 1;
MyMatrix[1, 0] = 5d;
But I found no easy way of doing this. I basically want the setter of the property to be able to take an object, but the get function will always return a Complex.
I could of curse do this:
public object this[int Row, int Col]
{
get { return matrix[Row, Col]; }
set
{
if (value is Complex)
{
matrix[Row, Col] = (Complex)value;
}
else if (value is double)
{
matrix[Row, Col] = new Complex((double)value, 0);
}
else if (value is int)
{
matrix[Row, Col] = new Complex((double)((int)value), 0);
}
else
{
throw new NotSupportedException("Not supported");
}
}
}
But that is really cumbersome when you want to get the value. Is there any tricks I could use to make this work properly?

I think I need some Coffee here. The complex class takes care of that for me

Just beat me. I was going to suggest looking at Complex constructors taking other numeric types and promoting.

I don't know if this type of structure (using a List of Lists instead of an Array) is relevant to your concerns, it's something I experimented with some time ago:
public class ComplexMatrix : List<List<Complex>>
{
public ComplexMatrix() { }
public ComplexMatrix(List<List<Complex>> list)
{
foreach(var lst in list) this.Add(lst);
}
public ComplexMatrix(IEnumerable<IEnumerable<Complex>> lstenum)
{
foreach (var lst in lstenum.ToList())
{
this.Add(lst.ToList());
}
}
public ComplexMatrix(int rows, int cols)
{
List<Complex> complexrow;
for (int i = 0; i < rows; i++)
{
complexrow = new List<Complex>(cols);
this.Add(complexrow);
for (int j = 0; j < cols; j++)
{
complexrow.Add(0.0d);
}
}
}
public Complex this[int row, int col]
{
set { this[row][col] = value; }
get { return this[row][col]; }
}
public void SetValue(int row, int col, double real, double imaginary)
{
this[row][col] = new Complex(real, imaginary);
}
}Sample use:
public void Test1()
{
var repeated1 = Enumerable.Repeat(Enumerable.Repeat(new Complex(1, 1), 5), 5);
var repeated2 = Enumerable.Repeat(Enumerable.Range(1, 6).Select(i => new Complex(i,i)), 6);
ComplexMatrix cmatrix0 = new ComplexMatrix(repeated1);
ComplexMatrix cmatrix1 = new ComplexMatrix(repeated2);
ComplexMatrix cmatrix2 = new ComplexMatrix(4,4);
cmatrix2.SetValue(0,0, 34.5, 666.4);
cmatrix2[2,2] = 4.0;
Complex c22 = cmatrix2[2,2];
ComplexMatrix cmatrix3 = new ComplexMatrix
{
{Enumerable.Repeat(new Complex(0.0,0.0), 2).ToList()},
{Enumerable.Repeat(new Complex(0.0,0.0), 2).ToList()}
};
cmatrix3[1, 1] = new Complex(3.4, 45.66);
Complex cmplx = cmatrix3[1, 1];
}Other than an interesting experiment in self-education re Enumerable.Repeat, Enumerable.Range, auto-initializers, and Indexers, etc.: meaning of-it-all is left up to you

It's a nice solution, although I prefer the Matlab coding style more, but that seems a bit cumbersome to implement in C#, like so:
var MyMatrix = [1,0,0 ;
0,1,0 ;
0,0,1]
Although I could use my previus developed code to do so:

I always end up questioning code I wrote (like the example shown here), wondering if it's "too clever by half," if it's just getting "fancy" for a relatively small gain in syntax clarity. And, how about "overhead:" memory use, relative speed ?
My reading of the discussions about Array vs. generic List in .NET re memory and speed from several years ago leaves me with a shaky conviction that using Arrays is a bit more efficient and faster, but, now that .NET has evolved, I'd need to refresh my knowledge of that.
Now, if I could only understand what Complex Numbers were: I mean I can relate in the sense that I often feel I have both an imaginary self as well as a "real" self
cheers, Bill
