wpf application was running very slow. I was using the performance profiling tools for wpf from windows and noticed my hardware IRTs per frame where very high (100+). that this is caused by some effects. After disabling some effects i found that this was the cause...
<Border.Effect>
<DropShadowEffect Direction="45" Color="#DDDDDD"/>
</Border.Effect>
[code].....
How do I apply effects such as a DropShadowEffect class to a TextBlock Run element in WPF?
Think of it as a way of highlighting certain areas of text in a TextBlock where the Run element is located, but applying an individual effect to that area instead.

I've been working on a project that requires that I can go around webpages with different proxies, user-agents, and clear cookies. Now after looking all around the net, it looks like there are some solutions for each of these, but I can never get them working. I was wondering if there was a wrapper for this control that fixed all of these problems or even just a different control I could include.

View 3 RepliesI was trying to put together a solution to:Insert spaces between words on a camel-cased token..Essentially, he wants to turn 'ThisIsATest' into 'This Is A Test'. I thought, 'Oh, that's easy, I can do it with LINQ' but I struggled with it. [code]Is the path I started to go down, but I'm having trouble getting the results into something I can work with. I even added the .ToString to try and get back an array of Strings, but I'm still getting an error.[code]I believe that means I'm getting a collection of System.Char, System.String instead of just a System.String like I want.
View 3 RepliesHow fast can I replace characters in a string?
So the background on this question is this. We have a couple of applications that communicate with each other and with client's applications through sockets. These socket messages contain non printable characters (e.g. chr(0)) which need to get replaced with a predetermined string (e.g "{Nul}"} because the socket messages are kept in a log file. On a side note, not every log message will need to have characters replaced.
Now I started off on this little adventure reading from This MSDN link which I found from a different post from this site.
The current method we used...at the beginning of the day...was using string builder to check for all the possible replacements such as...
Public Function ReplaceSB(ByVal p_Message As String) As String
Dim sb As New System.Text.StringBuilder(p_Message)
sb.Replace(Chr(0), "{NUL}")
[Code]....
This so far has been the fastest way I have found to process these messages. I have tried various other ways of going about this as well like converting the incoming string into a character array and comparing along with also trying to loop through the string rather than the chrArray.

I am trying to execute a command that works with hard coded variables, but when I try and replace the name test below with selectedname, I cannot get the syntax for escaping the command. The basic idea is I am using WMI to query the app pool names and then selecting one and storing in the slectedname variable, which works when I test with a msgbox(selectedname) line. It also shows up when I am stepping through, but does not get passed to the bottom command. The function where I am trying to execute the command is

I am doing some url redirections in a project that I am currently working on. I am new to web development and was wondering what the best practise was to remove any illegal path characters, such as ' ? etc.I'm hoping I don't have to resort to manually replacing each character with their encoded urls.
I have tried UrlEncode and HTMLEncode, but UrlEncode doesn't cater for the ? and HTMLEncode doesn't cater for '
E.G. If I was to use the following:
Dim name As String = "Dave's gone, why?"
Dim url As String = String.Format("~/books/{0}/{1}/default.aspx", bookID, name)
Response.Redirect(url)
I've tried wrapping url like this:
Dim encodedUrl As String = Server.UrlEncode(url)
And
Dim encodedUrl As String = Server.HTMLEncode(url)
to resolve this problem. User inputs a string and no.of replacement positions. for ex: l=7 and f=1 (L means length of string and f means replacement chars)

So I have a Powerpoint presentation. It contains numerous images on it, referred to by image X. (So it's the same image but on multiple pages) These same images on different pages/slides have different width/height attributes associated to them. So even though they're the same image, they may not be the same size.
So there exists a scenario where an image exists on a lot of the slides. I want the ability to replace all of them at the same time (quickly) without having to go through each slide and separately replacing X, one at a time with the new image.
Is this possible? (yes/no)How would this be accomplished? (abstract - high level explanation is only required)

i am loading an assembly with reflection through a partial name ... in this case "system"

Basically my issue is that users would like to search for a french word that has accented characters but without typing in the accented characters and then have the actual accented word appeared highlighted if found... So for example they would type in "declare" but in the result sets it would look like "déclare" and if found "déclare" would be highlighted.
My first thought was to just simply replace the characters with a regex but then I remembered that I would need to re-insert the replaced characters after the search... I was thinking of then using some sort of character map that would track position and the character so that when the search was finshed I could put the result set back to the way it was.

The application reads information similar to a DXF file. For purposes of discussion, the data consists of lines, those lines have endpoints, x1,y1,x2,y2. Within the file those lines create "paths", in other words, they are connected. There can be many separate paths within a single file. However in the original file, the geometry is not in any particular order, the paths are not indicated.
