View 4 RepliesReplace Keyword Within Html String?
Jan 13, 2010I 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, 2011I'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.

View 6 RepliesC# - Bug In The Matrix.RotateAt Method For Certain Angles?
May 24, 2010Here'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.
