Question

I came from C# background now im trying to write on VB NET.

I wrote a few rows in VB NET:

For Xcor = 0 To bmp.Width Step (bmp.Width / 10)

        For Ycor = 0 To Ycor <= bmp.Height Step 1


            pixelColor = bmp.GetPixel(Xcor, Ycor)

            hue = pixelColor.GetHue()
            saturation = pixelColor.GetSaturation()

            If ((hue > hueMin) AndAlso (hue < hueMax)) Then

                bmp.SetPixel(Xcor, Ycor, Color.Black)

            End If
          Next
      Next

In this row i get:

 For Ycor = 0 To Ycor <= bmp.Height Step 1

this error:

Type of ‘Ycor’ cannot be inferred from an expression containing ‘Ycor’.

Any idea how to fix the code?

Thank you in advance.

Answer 1

I think you just meant:

For Ycor = 0 To bmp.Height Step 1

Or equivalently, as per comments:

For Ycor = 0 To bmp.Height

VB For loops specify their bounds, not conditions. (Look at your Xcor loop, for example.)
