I am unable to change my volume using cd d: in command prompt using administrator rights. After typing this it just reopens c drive for me instead of opening d drive.  Edit   I came to a little solution that open the d drive using cd /d d: command but it is unable to open the e drive.
This may be a silly question, and I think I have looked elsewhere to find the answer...  Might be a path issue, but when I open the command line and type from the C:\&gt;: cd D:\  I cannot get to the D drive.  Even if I type: cd D:\&lt;folder name&gt;  The command.exe will auto-complete the line with the tab key, so it knows where I'm at.  It just doesn't print to screen the result or actually get me there.  This problem exists for the network drives as well. Now, if I use the chdir (cd) command like this: chdir D: or cd d: I get the print out of the D:\ below the command but it still says I'm in the C:\. I feel like I'm missing something simple.
java.lang.RuntimeException Cannot find FacesContext Inverse of function is continuous or not? If $f:I\subseteq \Bbb R \rightarrow \Bbb R$ is injective and everywhere continuous in its domain then $f^{-1}$ is also continuous everywhere. Here  $I$ cannot be discrete set and $f$ is single variable function The above statement is always correct or not? I thought it is always correct. Am I correct or not? I have keypair (u,r), and two pieces of data, X and Y.  I reveal X publicly but keep Y secret. Y has high entropy.  I then concatenate X and Y, into Z.  I encrypt Z, into "encrypt(Z,u) = Q". r is needed to decrypt Q back into Z.  Later, (when it doesn't matter), r will be revealed and everyone will decrypt Q into Z. At that point, everyone will know that, all along, Q "contained" X. Can I prove that Q contains X before r is revealed (including interactive zero-knowledge proofs)? A result of Stieltjes Integral While studying the Riemann - Stieltjes integral, I read this exercise in my book:  "Let $f:[a, b]\to \mathbb{R}$ be a bounded function. Denoted $L(P, f)$ the lower Darboux sum and $|P|$ the mesh of the partition $P$. Prove that for every $\epsilon&gt;0$, there exists $\delta&gt;0$ such that for every partition $P$ with $|P|&lt;\delta$, we have: $\underline{\int_{a}^{b}}f(x)dx-L(P, f)&lt;\epsilon$."  My question is: Can we generalize this problem for Stieltjes integral, with $\underline{\int_{a}^{b}}f(x)d\alpha$ instead of $\underline{\int_{a}^{b}}f(x)dx$?  Particularly, can we have this theorem?  Let $f:[a, b]\to \mathbb{R}$ be a bounded function and $\alpha$ is a monotonic function on $[a, b]$ . Denoted $L(P, f, \alpha)$ the lower Darboux sum and $|P|$ the mesh of the partition $P$. Prove that for every $\epsilon&gt;0$, there exists $\delta&gt;0$ such that $\underline{\int_{a}^{b}}f(x)d\alpha-L(P, f, \alpha)&lt;\epsilon$ for every partition $P$ with $|P|&lt;\delta$?  I don't know how the mesh of the partition relate to the function $\alpha$. Set the maximum character length of a UITextField Programming pattern to generate VGA signal with micro-controller? Registering a domain name with a trademark in it Convergence of $\sum_{n=1}^\infty (-1)^n(\sqrt{n+1}-\sqrt n)$ Please suggest some hint to test the convergence of the following series $$\sum_{n=1}^\infty (-1)^n(\sqrt{n+1}-\sqrt n)$$ I wonder about the foundations of set theory and my question can be stated in some related forms:   If we base Zermelo–Fraenkel set theory on first order logic, does that mean first order logic is not allowed to contain the notion of sets? The axioms of Zermelo–Fraenkel set theory seem to already expect the notion of a set to be defined. Is there are pre-definition of what we are dealing with? And where? In set theory, if a function is defined as a set using tuples, why or how does first order logic and the axioms of Zermelo–Fraenkel set theory contain parameter dependend properties $\psi(u_1,u_2,q,...)$, which basically are functions? I need to upload my signature in a PDF document, but I do not know how to edit the background of this image.   I wish to remove the bluish-tint background, and make it pure white.   Can anyone help me with this, please? Is it standard for graduate students to get gifts for their advisors? Is it standard for graduate students to give their advisors gifts around Christmas, like chocolates or bottles of wine?  What about other important people, such as their thesis committee members, or department secretaries? Is it possible to grant rename permissions, but not delete, in NTFS? We have a folder for employees to scan contracts to. After scanning, they're supposed to rename them according to our conventions so they can be processed further. In response to a recent incident, these folders have had their security locked down (they're granted write, but not modify, permission) and now they are unable to rename the files.  Is there a technical way to accomplish what I'm trying to do? From what I've read, I don't think this is possible.  If not, can you suggest any workarounds? One possibility is to set the name of the file as it's being scanned in. Another is to have a trusted person in management be given sufficient permissions to rename. What is the best way to replace the file browse button in html? I know that it's possible to replace the browse button, which is generated in html, when you use input tag with type="file.  I'm not sure what is the best way, so if someone has experience with this please contribute. I know how to CALCULATE dot product, but still don't understand MEANING of it.  I mean, If I have to explain vector addition I would say that "Sum of two vectors give you the third vector that has the same effect as other two combined"  But I don't know how to explain dot product. For example we have two vectors: v=(3,1) and w=(2,4). Dot product of these two is 3*2 + 1*4 = 10. What does this result (10) tell us? SSMS wont give up file associations Where is my Minecraft folder on Windows? I don't have a minecraft folder. I've looked through forums and videos, followed all the steps. I just don't have one. I have windows 7, and I have "view hidden files" turned on. I have look in the roaming folder of my app data folder, with hidden files turned on. I want to find my folder so I can install a mod, could someone please tell me why my folder isn't showing up? Why there is a $\frac{1}{2}$ in the distance formula $d=\frac{1}{2}at^2$? I found this interesting problem in :     Given a point $P$ in space, and given a piece of malleable material of constant density, how should you shape and place the material in order to create the largest possible gravitational field at $P$?   Any ideas? Why are objects at rest in motion through spacetime at the speed of light? I read that an object at rest has such a stupendous amount of energy, $E=mc^2$ because it's effectively in motion through space-time at the speed of light and it's traveling through the time dimension of space-time at 1 second per second as time goes forward.  What troubles me here, is the fact that it is traveling through space-time at the speed of light. Why is it at the speed of light? I'm trying to use Linq to return a list of ids given a list of objects where the id is a property. I'd like to be able to do this without looping through each object and pulling out the unique ids that I find.  I have a list of objects of type MyClass and one of the properties of this class is an ID.  public class MyClass {   public int ID { get; set; } }   What I want to do is write a Linq query to return me a list of those Ids  How do I do that given an IList&lt;MyClass&gt; such that it returns an IEnumerable&lt;int&gt; of the ids?  I'm sure it must be possible to do it in one or two lines using Linq rather than looping through each item in the MyClass list and adding the unique values into a list.  Any help in creating an elegant solution would be much appreciated!
