• ggplot2 pdf import in Adobe Illustrator missing font AdobePiStd

  - by Sander

  I created several simple ggplot2 plots and saved them to PDF files using the following commands: p <- ggplot(plotobject, aes(x=Pos, y=Pval),res=300) ggsave(plot=p,height=6,width=6,dpi=200, filename="~/example.pdf") If I now open this example.pdf in Adobe Illustrator I get the following error: The font AdobePiStd is missing. Affected text will be displayed using a substitute font. Is there a way in ggplot2 to specify a font (I presume this is for the dots/points) that Adobe will understand or otherwise is there a way to get this font working in Adobe?

• Retrieve Value Using Key From a Collection in Access 2000

  - by Mikecancook

  I know this is a simple question but it's aggravating me. If I have a key/value pair in a collection but I can't seem to get the value out using the key. I can get the key using the value but not vice versa. Is there some magical way to accomplish this? For example: Dim CycleList As Collection Dim Value as String Set CycleList = New Collection CycleList.Add 1, "Some Value" Value = CycleList(1) I've also tried CycleList.Item(1) and it's the same result, Value = 1.

• Saving a bitmap to a Memorystream produces an inverted colors image

  - by Raphael

  I've created an image with GDI+ on my application and now I must convert this image to an array of bytes. My first thought was this simple code: public byte[] ToByte() { MemoryStream ms = new MemoryStream(); bitmap.Save(ms, ImageFormat.Bmp); return ms.GetBuffer(); } The problem with this approach is that when I finally save this image into a file the colors are inverted. What I'm I doing wrong?

  - by Tal Galili

  Hi all, I am getting different results from ccf and cor, Here is a simple example: set.seed(100) N <- 100 x1 <- sample(N) x2 <- x1 + rnorm(N,0,5) ccf(x1,x2)$acf[ccf(x1,x2)$lag == -1] cor(x1[-N], x2[-1]) Results: > ccf(x1,x2)$acf[ccf(x1,x2)$lag == -1] [1] -0.128027 > cor(x1[-N], x2[-1]) [1] -0.1301427 Thanks, Tal

• Storing JSON in an msSQL database?

  - by JKirchartz

  I'm developing a form generator, and wondering if it would be bad mojo to store JSON in an SQL database? I want to keep my database & tables simple, so I was going to have `pKey, formTitle, formJSON` on a table, and then store {["firstName":{"required":"true","type":"text"},"lastName":{"required":"true","type":"text"}} in formJSON. would this slow down the DB server too much to set live? Any input is appreciated.

• Validate a number between 10 and 11 characters in length

  - by Montana Flynn

  I am using javascript (and PHP) to validate a simple form with a phone number field. I have it working fine checking that the field has only 10 characters, but I really want to check if the field has between 10 and 11 characters. Reason being, some people type numbers like so: 1 555 555 5555 and some people do this 555 555 5555. Here is what I have that works for checking if the length is 10: if (!(stripped.length == 10)) { alert("Please enter a valid US phone number.") return false }

• Why we need to read() before write() in TCP server program?

  - by Naga

  Hi, As per my understanding a simple TCP server will be coded as follows. socket() - bind() - listen() - accept() - read() - write() The clients will be written as follows. socket() - bind()(Optional) - connect() - write() - read() Please note the order difference in read() and write() calls between client and server program. Is it a requirement to always read() before write() in a server program and if, then why? Thanks, Naga

• Java - Console-like web applet.

  - by Dean

  Hey, I've been developing an application in the windows console with Java, and want to put it online in all of its console-graphics-glory. Is there a simple web applet API I can use to port my app over? I'm just using basic System.out and System.in functionality, but I'm happy to rebuild my I/O wrappers. I think something along these lines would be a great asset to any beginning Java developers who want to put their work online.

  I've been using the Semaphore class to create semaphores. However, the examples use managed code (requires /clr), and I need to use unmanaged code because it seems FreeType doesn't like working with managed code. How can I create two simple threads which use a semaphore in unmanaged code?

• How do I call a basic YUI3 function from within a normal JavaScript function?

  - by Justin Tanner

  I'd like to call a simple YUI3 function from within a JavaScript function. Here is some code that does what I want in a very verbose way: function changeContent (message) { YUI().use("node", function(Y) { Y.all('#content-div').setContent(message); }); } Is there a better way to do this? NOTE: I don't want to attach this function to any event, I just want a global changeContent() function available.

• How do I get just the x or y position of the background image using prototype?

  - by ro

  Hey, I'm making a simple user friendly css editor using Prototype. Anyway, I was wondering whether I could get the background-position x/y values on their own? I wish I could do something like this but sadly it doesn't work: element.getStyle('background-position-x); I guess this is because position comes in different forms like 'center' rather than just being generic.

• How do I load ascx pages faster in visual studio 2008?

  - by diadem

  One of my (my team's) biggest peeves with VS2008 is the slow speed in which ascx load. It could take up to a couple minutes to do something as simple as a text or style change simply because of the time it takes to load an ascx page into the visual studio text editor. Half the time I'm tempted to check out the file, edit it in notepad, then check it back in. Is there any trick to speeding this up?
