>Is it possible to get a control (e.g. a checkbox) and make a Graphics object or a Bitmap object of current face of the control?
The control may be hidden under some other forms or its Visible property
may
be set to false. I need to make a Bitmap or Graphics object that holds the
appearance of the control.

I know VB as well as C#. But the VB code does not show how to make a Bitmap
object from current face of a Control such as a TrackBar, CheckBox, etc.

Hamed,
As I said it is not my code, but a quick look in it shows me this. (I have
made two conversions to C# to show how easy it is to read VB as C# the
rest is almost adding some (), {} and the ; and removing the end clauses.
Dim bm As Bitmap
In C# this is
Bitmap bm;
If TypeOf objData Is String Then
Dim fs As New FileStream(objD ata.ToString,
FileMode.Open)
in C# this is
FileStream fs = new FileStream(objD ataToString, FileMode.Open);
bm = CType(Bitmap.Fr omStream(fs), Bitmap)
fs.Close()
Else
Try
bm = ConvertToBitmap (DirectCast(obj Data, Byte()),
78)
Catch
bm = ConvertToBitmap (DirectCast(obj Data, Byte()),
0)
End Try
End If
Dim h As Integer
Dim s As Double
Here is an image converted to a bitmap, so in my idea should using a
bitmap direct not change this code very much. However as I said in other
words already, bitmaps are not my favorite sport.

Hamed,
It seems that at least I have the idea where you are after.
Some of what you probably want to use is deep in Win32.
What you call the face is something I call the shape.
Although you can do a lot but doing that very deep is in my idea absolute
not a question for a newsgroup.
This is a simple sample to change the shape of a form. http://www.vb-tips.com/dbpages.aspx?...8-a2eda88e06ee

Hamed,
This is what i use to create a bitmap from a control:
Private Function _renderImageFro mControl(ByVal control As
System.Windows. Forms.Control) As System.Drawing. Bitmap
' Get this form's Graphics object.
Dim me_gr As System.Drawing. Graphics = control.CreateG raphics()
' Me._axFramerCon trol.CreateGrap hics
' Make a Bitmap to hold the image.
Dim bm As New System.Drawing. Bitmap(control. ClientSize.Widt h,
control.ClientS ize.Height)
Dim bm_gr As System.Drawing. Graphics =
System.Drawing. Graphics.FromIm age(bm)
Dim bm_hdc As IntPtr = bm_gr.GetHdc
' Get the form's hDC. We must do this after
' creating the new Bitmap, which uses me_gr.
Dim me_hdc As IntPtr = me_gr.GetHdc
' BitBlt the form's image onto the Bitmap.
BitBlt(bm_hdc, 0, 0, control.ClientS ize.Width,
control.ClientS ize.Height, me_hdc, 0, 0, SRCCOPY)
me_gr.ReleaseHd c(me_hdc)
bm_gr.ReleaseHd c(bm_hdc)
' Return the result.
Return bm
End Function
Hope this helps.

What you mentioned is a DataGrid ColumnStyle that shows images. The code the
I need is to make the bitmap from the control.
Suppose I have a hidden TrackBar that I want to show in the column of the
DataGrid. I want to make a Bitmap object from the TrackBar (that is hidden)
and paint the Bitmap in each cell.
How can I make a Bitmap object from the appereance of the control?

I am partially new in using newsgroups. sorry if this bothered you or any other here. I just wanted to know if I am sending the question to a wrong place or not. this is the case.
Anyway, I try to describe the problem in both threads further:
I am developing a ColumnStyle that holds a custom control ( a button or a numeric up down or something else )
I want to make a property that if set to true (I name it Sparse property) all cells of the grid is painted by the face of that control. Since we should implement the Paint method, I want to be able to paint the face of my custom control in the grid.

If you don't get an answer than has repeatly asking why that is no result. You see that in these newsgroups many people try to help as much as possible. The reason should therefore be in your own question.
There is a chance that nobody (at least for that message me) don't understand what you are asking.
Better is than to rephrase your message again in the same thread.
As well do people avoid persons who don't give any reaction on replies, because often people place a question and don't pay any attention than anymore to the given answers and the work that has done by that..
This kind of messages you write now is without sence and not liked in newsgroups , what can give the result that you get not any answer anymore.
I hope this gives some help,

Hamed,
Sorry forgot to include this code:
Private Declare Auto Function BitBlt Lib "gdi32.dll" (ByVal hdcDest
As IntPtr, ByVal nXDest As Integer, ByVal nYDest As Integer, ByVal
nWidth As Integer, ByVal nHeight As Integer, ByVal hdcSrc As IntPtr,
ByVal nXSrc As Integer, ByVal nYSrc As Integer, ByVal dwRop As
System.Int32) As Boolean
Private Const SRCCOPY As Integer = &HCC0020
Cheers,
Rob

Hamed,
This is what i use to create a bitmap from a control:
Private Function _renderImageFro mControl(ByVal control As
System.Windows. Forms.Control) As System.Drawing. Bitmap
' Get this form's Graphics object.
Dim me_gr As System.Drawing. Graphics = control.CreateG raphics()
' Me._axFramerCon trol.CreateGrap hics
' Make a Bitmap to hold the image.
Dim bm As New System.Drawing. Bitmap(control. ClientSize.Widt h,
control.ClientS ize.Height)
Dim bm_gr As System.Drawing. Graphics =
System.Drawing. Graphics.FromIm age(bm)
Dim bm_hdc As IntPtr = bm_gr.GetHdc
' Get the form's hDC. We must do this after
' creating the new Bitmap, which uses me_gr.
Dim me_hdc As IntPtr = me_gr.GetHdc
' BitBlt the form's image onto the Bitmap.
BitBlt(bm_hdc, 0, 0, control.ClientS ize.Width,
control.ClientS ize.Height, me_hdc, 0, 0, SRCCOPY)
me_gr.ReleaseHd c(me_hdc)
bm_gr.ReleaseHd c(bm_hdc)
' Return the result.
Return bm
End Function
Hope this helps.
Cheers,
Rob

I need simply a sparse property that I want to make in my inherited
DataGridColumnS tyle class
What you mentioned is a DataGrid ColumnStyle that shows images. The code
the
I need is to make the bitmap from the control.
Suppose I have a hidden TrackBar that I want to show in the column of the
DataGrid. I want to make a Bitmap object from the TrackBar (that is
hidden)
and paint the Bitmap in each cell.
How can I make a Bitmap object from the appereance of the control?

Hamed,
Maybe you can find on this page some stuff that can help you. (It is VB
but that is for most people easily to translate in C# stuff, as far as
I
could see is there in the code no part of the VB extensions on the
framework used). http://www.vb-tips.com/dbpages.aspx?...2-d85153e86736
And you were right, you missed the most propitiate newsgroup for this
question.
Microsoft.publi c.dotnet.framew ork.adonet
and the special datagrid newsgroups, but those are mainly inactive.
As I wrote this is not my stuff, Ken is active in the VB newsgroups and
forums, as you ask it there as well, will your question than of course
be
answered as well in VB code.
I hope this helps,
Cor

It becomes more clear, only there are AFAIK 5 types of Grid's in dotNet, which one is the one you want to inherit? Not that I know it, but I know active people in this newsgroup who have done a lot with this kind of stuff.

I am partially new in using newsgroups. sorry if this bothered you or any other here. I just wanted to know if I am sending the question to a wrong place or not. this is the case.
Anyway, I try to describe the problem in both threads further:
I am developing a ColumnStyle that holds a custom control ( a button or a numeric up down or something else )
I want to make a property that if set to true (I name it Sparse property) all cells of the grid is painted by the face of that control. Since we should implement the Paint method, I want to be able to paint the face of my custom control in the grid.
Now what is the solution for the above problem?
Regards

If you don't get an answer than has repeatly asking why that is no result. You see that in these newsgroups many people try to help as much as possible. The reason should therefore be in your own question.
There is a chance that nobody (at least for that message me) don't understand what you are asking.
Better is than to rephrase your message again in the same thread.
As well do people avoid persons who don't give any reaction on replies, because often people place a question and don't pay any attention than anymore to the given answers and the work that has done by that..
This kind of messages you write now is without sence and not liked in newsgroups , what can give the result that you get not any answer anymore.
I hope this gives some help,

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
