Including "{" -sign in string.Format I have a string which I want to insert an other string into. For this I use the method string.Format() but it doesn't work since my basestring include {-signs. As soon as I remove them from my string the code works fine.   string baseString = "This is my base string and when it includes {-signs it {0}.";  string insertString = "doesn't work";  string completeString = string.Format(baseString, insertString);   Does someone have a glue about why it doesn't work?
How to escape braces (curly brackets) in a format string in .NET How can brackets be escaped in using string.Format? For example: String val = &quot;1,2,3&quot; String.Format(&quot; foo {{0}}&quot;, val);  This example doesn't throw an exception, but it outputs the string foo {0}. Is there a way to escape the brackets?
I have a raster height model and would like to calculate the horizontal geographic direction (north, east, etc. - orientation) of each cell, then calculate then the mean value of all these cells in one region (polygon). This is to get information about to what direction a vineyard is exposed to. How do I do this? The question is to calculate the radius of convergence of $\sum\limits_{n=0}^\infty n!x^{n^2}$.  I dont know how to calculate R.O.C for such type of questions involving $n^2$ as power of x. How do we do this? Any help appreciated. You can reach this IP address  (if my computer is online).

I am trying to extract a value from a long string that may change over time. So for example the string could look something like this  ....../filename-1.9.0.3.tar.gz"&lt;....   And what I want to extract is the value between filename- and .tar.gz, essentially the file version (1.9.0.3 in this case). The reason I need to do it this way is because I may later run the command and the value will be 1.9.0.6 or 2.0.0.2 or something entirely different.  How can I do this? I'm currently only using grep, but I wouldn't mind using other utilities such as sed or awk or cut or whatever. To be perfectly clear, I need to extract only the file version part of the string, since it is very long (on both sides) everything else needs to be cut out somehow. If $a,b$ are positive integers such that $\gcd(a,b)=1$, then show that $\gcd(a+b, a-b)=1$ or $2$. and $\gcd(a^2+b^2, a^2-b^2)=1$ or $2 $ Remove category & tag base from WordPress url - without a plugin Is it possible to write one CSS rule for several prefixed selectors? Check if the application is already installed Prerequisites for AIC model comparison What are exactly the prerequisites, that need to be fulfilled for AIC model comparison to work?  I just came around this question when I did comparison like this:  &gt; uu0 = lm(log(usili) ~ rok) &gt; uu1 = lm(usili ~ rok) &gt; AIC(uu0) [1] 3192.14 &gt; AIC(uu1) [1] 14277.29   This way I justified the log transformation of variable usili. But I don't know if I can AIC-compare models when for example the dependent variable is different?  Ideal answer would include the list of prerequisites (mathematical assumptions). Remove Punctuation When Checking for Duplicate Titled Questions I recently saw a question titled "" (10k+ users only). I thought, "surely someone has asked this question before", and began looking for a duplicate.  is a question with the exact same title, just with a little different punctuation and casing. It was "Jquery vs Javascript" and "jQuery vs. Javascript?". The only difference being the ., ?, and the casing.  Since we now , I propose that when checking for questions with duplicate names, certain punctuation be striped out to prevent the duplicate from occurring in the first place.  As pointed out in the comments, if isn't already, white-space and non-printable characters may want to be removed for duplicate detection as well. Sending email with PHP from an SMTP server I have an input type="image". This acts like the cell notes in Microsoft Excel. If someone enters a number into the text box that this input-image is paired with, I setup an event handler for the input-image. Then when the user clicks the image, they get a little popup to add some notes to the data.  My problem is that when a user enters a zero into the text box, I need to disable the input-image's event handler. I have tried the following, but to no avail.  $('#myimage').click(function { return false; }); Does a Nikon DX lens on a FX camera get subjected to the 1.5X crop factor? Find Java classes implementing an interface Some time ago, I came across a piece of code, that used some piece of standard Java functionality to locate the classes that implemented a given interface. I know the functions were hidden in some non-logical place, but they could be used for other classes as the package name implied. Back then I did not need it, so I forgot about it, but now I do, and I can't seem to find the functions again. Where can these functions be found?  Edit: I'm not looking for any IDE functions or anything, but rather something that can be executed within the Java application.
