String Alignment - Align Properly As Mentioned In 1st Matrix

Aug 30, 2010

I want to format a string like this: (Properly right aligned)

0001215 0 0
000 216 0 0
000 016 0 0
000 016 0 0
000 816 8 5
00016161612
00016161612
00016161611
000 3 4 4 2

But my code gives results like this.

000121500
0002 16 0 0
0000 16 0 0
0000 16 0 0
0008 16 8 5
00016161612
00016161612
00016161611
0003 4 4 2

My code is:

string features = string.Empty;

for (int i = 0; i < 63;i++ )
{
features += (i % 7 == 0) ? "
" : "";
features += string.Format("{0,10} ", zoneFeatures[i]);

}

How do i align it properly as mentioned in 1st matrix ?

Replace Keyword Within Html String?

Jan 13, 2010

I am looking for a way to replace keywords within a html string with a variable. At the moment i am using the following example.

returnString = Replace(message, "[CustomerName]", customerName, CompareMethod.Text)

The above will work fine if the html block is spread fully across the keyword.eg.

<b>[CustomerName]</b>

However if the formatting of the keyword is split throughout the word, the string is not found and thus not replaced.e.g.

<b>[Customer</b>Name]

The formatting of the string is out of my control and isn't foolproof. With this in mind what is the best approach to find a keyword within a html string?

Project Which Involves Reading The Text From A Number Of Textboxes And Putting It Into A String?

Nov 15, 2011

I'm trying to do a project which involves reading the text from a number of textboxes and putting it into a string.I'm just wondering if there's an easier way to it other than:

CreateString += TextBox1.Text + TextBox2.Text + TextBox3.Text... (etc)

I have thought about creating a For Next loop which would go something like:

For i As Integer = 0 To intNoTextBoxes
CreateString += TextBox(i).Text
Next

But this really doesn't work. I also found something saying that something similar to this would work:

For i As Integer = 0 To intNoTextBoxes
CreateString += Me.Controls.Item("TextBox" & i.ToString).Text
Next

But that didn't work either.

C# - Bug In The Matrix.RotateAt Method For Certain Angles?

May 24, 2010

Here's the code i'm using to rotate:

Dim m As New System.Drawing.Drawing2D.Matrix
Dim size = image.Size
m.RotateAt(degreeAngle, New PointF(CSng(size.Width / 2), CSng(size.Height / 2)))
Dim temp As New Bitmap(600, 600, Imaging.PixelFormat.Format32bppPArgb)
Dim g As Graphics = Graphics.FromImage(temp)
g.Transform = m
g.DrawImage(image, 0, 0)

(1) Disposals removed for brevity.

(2) I test the code with a 200 x 200 rectangle.

(3) Size 600,600 it just an arbitrary large value that I know will fit the right and bottom sides of the rotated image for testing purposes.

(4) I know, with this code, the top and left edges will be clipped because I'm not transforming the orgin after the rotate.

The problem only occurs at certain angles:

(1) At 90, the right hand edge disappears completely.
(2) At 180, the right and bottom edges are there, but very faded.
(3) At 270, the bottom edge disappears completely.

Is this a known bug?If I manually rotate the corners an draw the image by specifying an output rectangle, I don't get the same problem - though it is slightly slower than using RotateAt.
