• Build comma seperated string from the struct in C#

  - by acadia

  Hello, I have the following struct in C# class public struct Employee { public const string EMPID = "EMP_ID"; public const string FName = "FIRST_NAME"; public const string LNAME = "LAST_NAME"; public const string DEPTID = "DEPT_ID"; } Is there an easy way to build a string as follows const string mainquery="INSERT INTO EMP(EMP_ID,FIRST_NAME,LAST_NAME,DEPT_ID) VALUES(:EMP_ID,:FIRST_NAME,:LAST_NAME,:DEPT_ID)" Instead of doing as follows and then concatenating it. const string EMP_COLS= EMPLOYEE.EMPID + "," + EMPLOYEE.FNAME + "," + EMPLOYEE.LNAME + "," + EMPLOYEE.DEPTID; const string EMP_Values= EMPLOYEE.EMPID + ":" + EMPLOYEE.FNAME + ":" + EMPLOYEE.LNAME + ":" + EMPLOYEE.DEPTID;

• Is there a good way to remove a character from a string without copying all the characters following

  - by piemesons

  I was given an interview question: // The first example: char text[] = "henri"; char *p; p = text; *(p + 1) = 'E'; // Output = hEnri // Now If we want to remove the "e" ie hnri, we would go for????? *(p + 1)=????? The obvious answer is to copy the rest of the array "back" one position. But this seems... unpleasant. Surely there is some better way?

• how to retrieve substring from string having variable length of character in php?

  - by user187580

  Hello I have some data in the format of C222 = 50 C1234P687 = 'some text' C123YYY = 'text' C444 = 89 C345 = 3 C122P687 = 'some text' C122YYY = 'text' .... .... so basically 3 different forms "C" number = value, example - C444 = 89 "C" number "P" number = value, example - C123P687 = 'some text' "C" number "YYY" = value Only number is of variable length on the left side of (=) sign. Values vary. I want to store the data in db as INSERT INTO datatable c_id = "number after C" p_id = "number after P" // if it exists for a line of data value = 'value' yyy = 'value' Any ideas how to retrieve these numbers? Thanks

• Meta package / quick reference for string manipulation commands?

  - by Dylan McCall

  The latest version of the Scribes text editor lets us select some text, hit Alt+X, and then run an arbitrary command. For example, I can run the sort command and the selected text is replaced appropriately. This is quite useful but I am also not very well-versed in awk and the like. Is there something I can grab that will provide more of these commands like sort? Maybe a package with a whole bunch of handy, task-specific string manipulation commands?

• Chrome causing 404's ending with "/cache/[hex-string]/"?

  - by Jan Fabry

  Since the last weeks we see many 404's on our sites caused by Chrome adding /cache/[hex-string]/ to the current page URL. The hex strings we have seen are: e9c5ecc3f9d7fa1291240700c8da0728 1d292296547f895c613a210468b705b7 408cfdf76534ee8f14657ac884946ef2 9b0771373b319ba4f132b9447c7060a4 b8cd4270356f296f1c5627aa88d43349 If you search for these strings you get matches from different sites, but they are most likely auto-generated (/search/cache/e9c5ecc3f9d7fa1291240700c8da0728/ for example). Is this a known issue with Chrome (or an extension)?

• New DMF for SQL Server 2008 sys.dm_fts_parser to parse a string

  Many times we want to split a string into an array and get a list of each word separately. The sys.dm_fts_parser function will help us in these cases. More over, this function will also differentiate the noise words and exact match words. The sys.dm_fts_parser can be also very powerful for debugging purposes. It can help you check how the word breaker and stemmer works for a given input for Full Text Search.

• What is the difference in RAM speeds?

  - by jasondavis

  I am building a new PC with the intel i7-930 processor. I am wanting to use 12gb of RAM for it (6x2gb sticks). Here is some of the RAM I am looking at G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop 2 of these 3 stick kits. They are rated at 1600 however some of the user reviews on that product say they xcould not get it to run at 1600 and the supplier who makes the RAM made a comment that "I7 doesn't support over DDR3 1066" So I am curious, I do not know much about this, I know the more GB of RAM the better but as for the speeds, I am not sure how much of a difference it makes. So can someone explain to me what the difference in performance may be based on speeds of 1200 vs 1600 ram?

• OpenVZ vs Xen, how much difference in performance?

  - by Aleksandr Levchuk

  There is a Xen vs. KVM in performance question on ServerFault. What will be the performance difference if the choice is between Xen and OpenVZ? How is it best to measure? Some may say "you're comparing apples and oranges" but I have to choose one of the two and it needs to be wise choice. Performance is most important to us. We may switching to Xen from OpenVZ because Xen is more ubiquitous but only if performance difference is not significant. In January 2011 I'm thinking of doing a head to head performance comparison - here is my project proposal to our Bioinformatics facility director.

• Difference in VISUAL STUDIO VERSIONS

  - by karthik ram

  I would like to understand some fundamental VS version differences, What is the difference between Visual Studio 2008 and Visual Studio 2008 Team System? Does the Team System 2008 include VS2008, TFS 2008 & Team Explorer 2008? Furthermore, what is the difference betwene Team System 2008 and Team Suite 2008? I beleive there are no more Team Suites or Team Systems in 2010? Does Visual Studio Ultimate 2010 include all Team System components, like TFS 2010 & Team Explorer 2010, so in effect it is like an upgrade of Visual Studio 2008 Team System? Or does TFS 2010 & Team Explorer 2010 need to be installed separately?
