Hmm....
xp is set to 4294967295 and does not change with each loop... y, however, does as is wanted.

Okay, fixed that. Still get the same output, though.

Hmm.... I tried recreating the file using the other program(which uses the same values in bmp and bfh) using the CREATE_NEW definition in the CreateFile() function. When I do this, the resulting image cannot be drawn by windows picture and fax viewer. This may be the problem...

Sounds like a clue to me.  I'm not really up on that kind of file I/O. I rarely store things these days.

You've gone quiet. Did you ever get it to work? Inquiring minds want to know.

Unfortunately I haven't got it to work yet.
I shall keep at it, however.

I am using Datagrid in my application. And at the same time i want to highlight particular row in datagrid.
Using graphics class i tried to draw a rectangle on the row but drawn rectangle is invisible.
In formload, datagrid is there. And in application depending upon the event rectangle should be drawn on the datagrid on particular row.
Please assist me in this.

Didn't you just ask this same question about 2 messages below using the name gayatrit, delete it, set up a new ID, and ask it again?

foreach (DataGridViewRow row in dataGridView.Rows)
{
row.DefaultCellStyle.BackColor = Color.Tomato;
}
You can add if statements within the foreach to change row colors according to conditions like so
foreach (DataGridViewRow row in dataGridView.Rows)
{
if (row.Cells[13].Value.ToString() == "someValue")
{
row.DefaultCellStyle.BackColor = Color.Tomato;
}
else if(row.Cells[13].Value.ToString() == "someOtherValue")
{
row.DefaultCellStyle.BackColor = Color.Blue;
}
}
hope it helps

You're not giving us a lot to work with in how you're doing it but sounds like it might be an order of operations issue. You draw your rectangle first and then the datagrid draws over it. That's why when you set it to invisible, it doesn't tromp all over your rectangle.
If you don't have the data, you're just another a**hole with an opinion.

Hi Group,
I have a little app that loads a PNG image (128x128x32), and draws it to another canvas, with scaling. The destination size is 512x512, and, using VB.net, I use the commands (g is a graphics Canvas)
g.FillRectangle(Brushes.White, New Rectangle(0, 0, 512, 512))
g.DrawImage(Img, 0, 0, 512, 512)
However, the image drawn to the canvas is more like 560x560 pixels.
Does anyone know why this is happening? The source image is definately 128x128, and is 72dpi... although this shouldnt affect anything... should it?
Thanks,
Jason

How about trying DrawImageUnscaled?

Hi Leppie,
That wont work - I need the image scaling.
Looking around a bit, I think that GDI+ is being too clever. I noticed that the PNGs that didnt work well had a different Dots-per-inch setting to ones that did.
So, I suppose I aught to amend my question to say how do I get GDI+ to ignore these values, and simply do what I asked of it - scale a bitmap to fit a rectangle
 
thanks
Jason

I don't htink GDI+ does anything with DPI. You can set DPI in code tho, if you need to try that.

I just posted this in the VB group, but then realized that this is most likely the proper place to post my question. Here it goes:
I have opened an image as a bitmap using GDI+. Before I save it I want to know if the image has transparency in it. That is; is there any pixels in the bitmap that has the transparent color? I have made a solution that looks like this:
Dim objImage As Drawing.Bitmap = Drawing.Image.FromFile("png_with_transparent_bg.png")
Dim booTransparentColorFound As Boolean = False
If Bitmap.IsAlphaPixelFormat(objImage.PixelFormat) Then
For y As Integer = 0 To objImage.Height - 1
If booTransparentColorFound Then Exit For
For x As Integer = 0 To objImage.Width - 1
Dim objColor As Drawing.Color = objImage.GetPixel(x, y)
If objColor.A = Color.Transparent.A And _
objColor.R = Color.Transparent.R And _
objColor.G = Color.Transparent.G And _
objColor.B = Color.Transparent.B _
Then
booTransparentColorFound = True
Exit For
End If
Next
Next
End If
The problem is that if the image is very big, and there is no transparent pixel in it (or a transparent pixel is located in the lower right corner), the routine is very slow. Is there some quicker way to determine if there is transparency in the image?
Thanks in advance.

There are two things you could do (first way will not speed up the processing but is just a method improvement):
1) Only need to check the alpha channel (assuming any transparent colour is counted)...
If objColor.A != 255 Then ...
(As the alpha channel IS the 'trasparency' aspect of the colour, you only need to check this).
2) Lock the Bitmap and loop through the raw data (this is REALLY fast)... loads of examples on web... from msdn[^]
Also... if all you want to know is if the image could contain transparency... check the PixelFormat of the bitmap for transparency.
Hope this helps.
