  • How to check CPU temperature on a HP P2000?

    - by Pavel
    I have a HP StorageWorks MSA Storage P2000 G3 SAS. show sensor-status gives something like # show sensor-status Sensor Name Value Status ---------------------------------------------------- On-Board Temperature 1-Ctlr A 53 C OK On-Board Temperature 1-Ctlr B 52 C OK On-Board Temperature 2-Ctlr A 61 C OK On-Board Temperature 2-Ctlr B 63 C OK On-Board Temperature 3-Ctlr A 53 C OK On-Board Temperature 3-Ctlr B 53 C OK Disk Controller Temp-Ctlr A 34 C OK Disk Controller Temp-Ctlr B 32 C OK Memory Controller Temp-Ctlr A 66 C OK Memory Controller Temp-Ctlr B 67 C OK [...] Overall Unit Status OK OK Temperature Loc: upper-IOM A 40 C OK Temperature Loc: lower-IOM B 38 C OK Temperature Loc: left-PSU 36 C OK Temperature Loc: right-PSU 40 C OK [...] is one of the values the CPU/FPGA temperature? Or, if not, how do I get it? Thanks!

  • Roaming user profile issues on Server 2008

    - by Alicia White
    I thought I cleared a user's profile from 2008, but it keeps coming back. So, I was looking for the best way to clear a roaming profile in Server 2008, but I have been unable to find anything. But, I did see the post here: http://serverfault.com/questions/18724/user-profile-keeps-loading-temp-profile I wanted to add a comment to that post, but it was closed as not being related to sysadmin. But, I think it IS related because I dealt with precisely this same problem on our Wndows 2008 terminal server. Here was the issue: we have a user who was getting an "unable to load your roaming profile" type of error at logon in Windows 2008. Looking at the server, we could see her temp profile listed in the profile list while she was loggged (listed as a "temporary" and not a "roaming" profile). While she was logged on, a folder called C:\Users\Temp.DOMAIN existed in the users folder, but that disappeared as soon as she logged out. When this thing happened in 2003, we would clear the contents of the roaming profile folder & delete the temp folder in C:\Documents and Settings. The thing is, 2008 behaves a bit differently. Server 2008 created a new roaming profile folder in the roaming profile folder share: \SERVER\ProfileShare\UserName.V2 The local profile disappears from the profile list in System Properties, so there is no profile to clear Also the local profile folder, C:\Users\Temp.DOMAIN doesn't stay on the server when the user logs out, so we can't delete that as we would normally do when this sort of thing happens in Windows 2003 Despite all of this, every time the user logs back on, the frickin' Temp profile always comes back. One of my team-mates, who is much more experienced with 2008, said I should check the registry for the user's profile in this key (the users are listed by SID): HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\ProfileList I saw the user's SID listed there, but it ended in .BAK. I checked several other servers where she is having the same profile errors: in all cases, her SID ended with .BAK. For example (xxx replacing the LONG SID): HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-xxxxx-xxxx.bak On the server she was logged on to, there were two keys for her profile in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-xxxxx-xxxx and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-xxxxx-xxxx.bak So, here is how I cleared up the issue. I had the user log off. I deleted the apparently bad profiles ending in .BAK from the ProfileList key on each server where it appeared. I made sure her roaming profile folder was empty I made sure that all the TEMP profile folders were gone The user logged back on: no more profile errors! Anyway, I wanted to make a comment on that closed question, but I didn't see any way to re-open the question so I could add it. But, I also would like to know if this is the best practice to clear out a bad roaming profile for Server 2008? I'm having a hard time finding any instructions on line on how best to do this, but this method I used seemed to work. I'd like to find some documentation to give to our Level 1 support staff so they will know how to clear user profiles on 2008 since this seems to be more involved that clearing user profiles in server 2003. Thanks, Alicia

  • LSI MegaRAID Expected Chip Temperature?

    - by Myles Gray
    We recently built a replicating SAN array from 2x Dell R720XD's, we are using LSI 9270-8i MegaRAID cards with CacheCade 2.0, BBU and Write Back cache enabled. Our cards are showing HUGE chip temperatures (97*C+ with NO disk activity!). Our R720's are in auto temp management mode so the max exhaust temp is 50*C. The MegaRAID cards are passively cooled and depend on good airflow to cool them - however is 97*C normal? - I have seen reference to 60*C max ambients but nothing for chip temp.

  • PHP ignores upload_tmp_dir?

    - by Matthias Vance
    LS, I am using IIS7 with PHP (FastCGI). I set up the upload_tmp_dir to "X:\Temp" instead of leaving it empty, but it's still using "C:\Windows\Temp" for some reason. I did give the following users full rights : NETWORK SERVICE, (application pool user), IIS_IUSRS. I also restarted IIS after I made the change. I tried to create a directory inside the correct temp path using PHP, and that did work, so it's not a security issue. Kind regards, Matthias Vance

  • Why can't Logman start?

    - by Bill Paetzke
    I'm setting up my first logman counter. But it's not working! There is some file or folder permissions problem. Or maybe I wrote the create-counter statement wrong. Here's my counter commands: logman create counter BillTest -si 30 -v nnnnnn -max 200 -o "C:\Temp" -c "\Processor(*)\*" "\Memory(*)\*" "\LogicalDisk(*)\*" logman start BillTest The first command works. It says counter creation successful. The second command fails: Collection "BillTest" did not start, check the application event log for any errors Here's the error in the Event Viewer: The service was unable to open the log file C:\Temp_000001.blg for log BillTest and will be stopped. Check the log folder for existence, spelling, permissions, and ensure that no other logs or applications are writing to this log file. You can reenter the log file name using the configuration program. This log will not be started. The error returned is: Access is denied. I verified that C:\Temp exists. I'm not a permissions guru, but I did set all the accounts in the security tab of that folder to "full control." Still, the logman start command failed with the same error. I noticed that it was trying to write to C:\Temp_000001.blg instead of C:\Temp\000001.blg. That might be part of the problem. So, I tried to update my counter to "C:\Temp\" instead of "C:\Temp", but that failed with a path-invalid error. Also, all the examples I saw online used did not put a trailing slash. So, no dice there. I tried this on my machine (Windows XP) and my dev server (Windows Server 2003). Both failed with the same error. How can I fix this?

  • Installing/enabling PHP Pecl Intl extension on CentOs 5

    - by Marijn Huizendveld
    Original question: I'm having trouble installing the PHP Pecl Intl extension on my CentOs 5 machine. After installing both icu and libicu with the following commands: $ yum install icu $ yum install libicu I tried to install the Intl extension like so: $ /usr/bin/pecl install intl I selected to search for the default location for the ICU libraries and header files. It ends up crashing like this: checking whether to enable internationalization support... yes, shared checking for icu-config... no checking for location of ICU headers and libraries... not found configure: error: Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works. ERROR: `/tmp/pear/temp/intl/configure --with-icu-dir=DEFAULT' failed update After successfully installing the development version of icu as suggested by RusAlex (thanks RusAlex) like so: $ yum install libicu-devel I ran into a new problem which I also encountered locally the following command: $ /usr/bin/pecl install intl now produces this error: /private/tmp/pear/temp/intl/collator/collator_class.c:92: error: duplicate 'static' /private/tmp/pear/temp/intl/collator/collator_class.c:96: error: duplicate 'static' /private/tmp/pear/temp/intl/collator/collator_class.c:101: error: duplicate 'static' /private/tmp/pear/temp/intl/collator/collator_class.c:107: error: duplicate 'static' make: *** [collator/collator_class.lo] Error 1 ERROR: `make' failed It appears to have something to do with PHP 5.3 being bundled with Intl already. But how can I enable this extension, if I look in my PHP Info than I cannot find any reference to it...

  • A keyboard shortcut from a sequence of keystrokes for Linux

    - by Little Bobby Tables
    I am looking for a way to define an Emacs-style keys sequence as a keyboard shortcut in Linux - Specifically, in Gnome, but more general solutions are also acceptable. For example, I would like a sequence like "Alt-w t" (that is, first press Alt-w and then t) to open a terminal, "Alt-w c" to close a window, and so on. The rationale behind this question is twofold: Make more use of desktop-wide keyboard shortcuts Make an old keyboard, that has no Win key, usable with desktop-wide keyboard shortcuts, without causing too many collisions with application - Specifically with Emacs. Thanks!

  • Change the output format of zsh's time

    - by YGA
    Hi Folks, I've just switched to zsh. However, I really don't like how the time builtin command also outputs the command that it's timing. I much prefer the bash style output. Anyone know how to switch it over? Zsh: [casqa1:~/temp]$ time grep foo /dev/null /usr/local/gnu/bin/grep --color -i foo /dev/null 0.00s user 0.00s system 53% cpu 0.004 total Bash: [casqa1:~/temp]$ bash casqa1.nyc:~/temp> time grep foo /dev/null real 0.0 user 0.0 sys 0.0 Thanks, /YGA

    My system is running on a pc with C:\ Drive out of space. So I tried to delete some file and clean up to get more space. I found that the %Temp% {C:\Users\Username\AppData\Local\Temp} takes lots of space and tried to delete files in it. But when I open it , it alerted me with the message C:\Users\Username\AppData\Local\Temp is not accessible The file or directory is corrupted and unreadable? What to do? Is deleting files from Temp harmful to computer?

  • Emacs and windows manager keyboard shortcuts without Win key

    - by Little Bobby Tables
    I found a classic M-Series keyboard and I want to use it. However, it does not have the "Windows" key (a.k.a "Super"), only the Shift, Control and Alt modifiers. My keyboard shortcuts are cluttered as-is, since that I try to control both Emacs and the windows manager (Gnome) only from the keyboard. I rely on the "Super" key to identify the windows manager shortcuts. What it the best practice for keyboard-centric work without the "Super" key?

  • Serious voltage and temperature problems

    - by James Willson
    My computer has been acting up when I play games so I wanted to look into why. Issue 1: GPU Temp According to afterburner and speedfan my 8800GTX idles at 90 degrees and then when playing games shoots up to over 110C which is when my graphics basically starts to give rendering issues. Issue 2: CPU Temp Speedfan is saying my CPU temp is 83C idle but when I look at core temp it says core0 is at 35C and core1 is at 33C. Issue 3: Voltages This is what speedfan is saying for my voltages: Vcore1: 1.01V Vcore2: 1.90V +3.3V: 3.31V +5V: 4.95V +12V: 0.51V -12V: -16.80V -5V: -8.43V +5V 5.13V Vbat: 3.25V Vcore: 3.00V +3.3V: 3.20V These voltages, for lack of a better word, look f*cked. With all this happening, the computer runs ok under normal use. Is the software giving out incorrect readouts or instead should I immediately move the computer into another room before it explodes? P.s I would like to add this is a stock system. EVGA 8800GTX, E6850 CPU, 800W PSU

  • Windows 7 automatically logs out when logging in

    - by Luke
    A Windows 7 HP x64 computer is set to automatically log in (no password), but once it starts logging in, it starts to load the desktop after the welcome screen, but before icons or background images are loaded, it goes to the Welcome screen saying 'Logging Off'. I can log in with Safe Mode, and I ran a couple different virus scans, with no detections. I also tried checking the userinit.exe file in System32 (as suggested by MANY users for Windows XP), but it's the same version as a working system. I also checked the registry under HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon for the SHELL and UserInit values, but they look normal. I tried to disable all startup items (through MSCONFIG) to select Diagnostic boot, but then I get a blue screen about the video driver not loading. Any other ideas? EDIT I created a new user, and it could log in no problems. I am thinking it's the NTUSER.DAT file. I just renamed it to NTUSER.DAT.old, then tried logging in as the problem user. I could log in, but as a TEMP profile. His profile folder is now C:\Users\TEMP, and his old folder is still accessible but in the wrong location. EDIT 2 I can't seem to turn off the TEMP profile, so I'm open to other suggestions. Copying the folders (i.e. Documents, Music, etc) does not work, as it creates an additional TEMP.000 then TEMP.001 folder each time the user logs in.

  • IIS returning plain Forbidden response. No HTTP code

    - by Alex Pineda
    I'm running a ServiceStack application on IIS. My regular services work fine and have not had any problems with permissions. My new project involves providing generated pdfs. I gave IIS_IUSRS read/write permissions to the Temp directory under my app directory. I also allow non SSL connections to this directory. When I browse to the file which ServiceStack is supposed to automatically serve up (eg. http://ryu.com/Temp/201310171723337631.pdf ) I get this: Forbidden Request.HttpMethod: GET Request.PathInfo: Request.QueryString: Request.RawUrl: /ryu/Temp/201310171723337631.pdf App.IsIntegratedPipeline: True App.WebHostPhysicalPath: C:\inetpub\ryu App.WebHostRootFileNames: [global.asax,global.asax.cs,web.config,bin,temp] Now this doesn't look like a ServiceStack error message, more like IIS, but I'm not certain as to how to get to the bottom of this. Authorization settings are Allow All.

  • Windows command FOR /F isn't working?

    - by Mark Ransom
    I'm trying to use the FOR command in Windows XP's command line. I have a file temp.txt with 3 lines: temp1 temp2 temp3 And I'm typing the following command at the prompt: for /F %p in (temp.txt) do echo Testing %p Nothing comes back. If I remove the /F parameter, the output is Testing temp.txt. As far as I can determine, I'm using the command exactly as it is documented by Microsoft. I've checked my registry to make sure Command Extensions are on, and even started a new shell with cmd /e:on to be doubly sure. What am I doing wrong? Yes, I was doing something wrong. The file temp.txt wasn't created from scratch, I just edited it to put in my test content. Unfortunately when I created the file the first time, I saved it with a UTF-8 marker at the front. Recreating the file as plain text solved the problem.

  • Resolving html entities with NSXMLParse on iPhone

    - by Roberto
    Hi all, i think i read every single web page relating to this problem but i still cannot find a solution to it, so here i am. I have an HTML web page wich is not under my control and i need to parse it from my iPhone application. Here it is a sample of the web page i'm talking about: <HTML> <HEAD> <META http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> </HEAD> <BODY> <LI class="bye bye" rel="hello 1"> <H5 class="onlytext"> <A name="morning_part">morning</A> </H5> <DIV class="mydiv"> <SPAN class="myclass">something about you</SPAN> <SPAN class="anotherclass"> <A href="http://www.google.it">Bye Bye &egrave; un saluto</A> </SPAN> </DIV> </LI> </BODY> </HTML> I'm using NSXMLParser and it is going well till it find the è html entity. It calls foundCharacters: for "Bye Bye" and then it calls resolveExternalEntityName:systemID:: with an entityName of "egrave". In this method i'm just returning the character "è" trasformed in an NSData, the foundCharacters is called again adding the string "è" to the previous one "Bye Bye " and then the parser raise the NSXMLParserUndeclaredEntityError error. I have no DTD and i cannot change the html file i'm parsing. Do you have any ideas on this problem? Thanks in advance to all of you, Rob. Update (12/03/2010). After the suggestion of Griffo i ended up with something like this: data = [self replaceHtmlEntities:data]; NSXMLParser *parser = [[NSXMLParser alloc] initWithData:data]; [parser setDelegate:self]; [parser parse]; where replaceHtmlEntities:(NSData *) is something like this: - (NSData *)replaceHtmlEntities:(NSData *)data { NSString *htmlCode = [[NSString alloc] initWithData:data encoding:NSISOLatin1StringEncoding]; NSMutableString *temp = [NSMutableString stringWithString:htmlCode]; [temp replaceOccurrencesOfString:@"&amp;" withString:@"&" options:NSLiteralSearch range:NSMakeRange(0, [temp length])]; [temp replaceOccurrencesOfString:@"&nbsp;" withString:@" " options:NSLiteralSearch range:NSMakeRange(0, [temp length])]; ... [temp replaceOccurrencesOfString:@"&Agrave;" withString:@"À" options:NSLiteralSearch range:NSMakeRange(0, [temp length])]; NSData *finalData = [temp dataUsingEncoding:NSISOLatin1StringEncoding]; return finalData; } But i am still looking the best way to solve this problem. I will try TouchXml in the next days but i still think that there should be a way to do this using NSXMLParser API, so if you know how, feel free to write it here :)

  • Is C# slower than VB.NET?

    - by Matt Winckler
    Believe it or not, despite the title, this is not a troll. Running some benchmarks this morning, my colleagues and I have discovered some strange things concerning performance, and I am wondering if we're doing something horribly wrong. We started out comparing C# vs. Delphi Prism calculating prime numbers, and found that Prism was about 30% faster. I figured maybe CodeGear did more optimization when generating IL (the exe was about twice as big as C#'s and had all sorts of different IL in it.) So I decided to write a test in VB.NET as well, assuming that Microsoft's compilers would end up writing essentially the same IL for each language. However, the result there was more shocking: C# was more than three times slower than VB running the same operations. The generated IL was different, but not extremely so, and I'm not good enough at reading it to understand the differences. As a fan of C#, this apparent slowness wounds me horribly, and I am left wondering: what in the world is going on here? Is it time to pack it all in and go write web apps in Ruby? ;-) I've included the code for each below--just copy it into a new VB or C# console app, and run. On my machine, VB finds 348513 primes in about 6.36 seconds. C# finds the same number of primes in 21.76 seconds. (I've got an Intel Core2 Quad Q6600 @2.4Ghz; on another Intel machine in the office the code for both runs much faster but the ratio is about the same; on an AMD machine here the timing is ~10 seconds for VB and ~13 for C#--much less difference, but C# is still always slower.) Both of the console applications were compiled in Release mode, but otherwise no project settings were changed from the defaults generated by Visual Studio 2008. Is it a generally-known fact that C#'s generated IL is worse than VB's? Or is this a strange edge case? Or is my code flawed somehow (most likely)? Any insights are appreciated. VB code Imports System.Diagnostics Module Module1 Private temp As List(Of Int32) Private sw As Stopwatch Private totalSeconds As Double Sub Main() serialCalc() End Sub Private Sub serialCalc() temp = New List(Of Int32)() sw = Stopwatch.StartNew() For i As Int32 = 2 To 5000000 testIfPrimeSerial(i) Next sw.Stop() totalSeconds = sw.Elapsed.TotalSeconds Console.WriteLine(String.Format("{0} seconds elapsed.", totalSeconds)) Console.WriteLine(String.Format("{0} primes found.", temp.Count)) Console.ReadKey() End Sub Private Sub testIfPrimeSerial(ByVal suspectPrime As Int32) For i As Int32 = 2 To Math.Sqrt(suspectPrime) If (suspectPrime Mod i = 0) Then Exit Sub End If Next temp.Add(suspectPrime) End Sub End Module C# Code using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Diagnostics; namespace FindPrimesCSharp { class Program { List<Int32> temp = new List<Int32>(); Stopwatch sw; double totalSeconds; static void Main(string[] args) { new Program().serialCalc(); } private void serialCalc() { temp = new List<Int32>(); sw = Stopwatch.StartNew(); for (Int32 i = 2; i <= 5000000; i++) { testIfPrimeSerial(i); } sw.Stop(); totalSeconds = sw.Elapsed.TotalSeconds; Console.WriteLine(string.Format("{0} seconds elapsed.", totalSeconds)); Console.WriteLine(string.Format("{0} primes found.", temp.Count)); Console.ReadKey(); } private void testIfPrimeSerial(Int32 suspectPrime) { for (Int32 i = 2; i <= Math.Sqrt(suspectPrime); i++) { if (suspectPrime % i == 0) return; } temp.Add(suspectPrime); } } }

  • Problem with reading file line-by-line

    - by Maulrus
    I'm trying to complete an exercise to write a program that takes the following command line arguments: an input file, an output file, and an unspecified number of words. The program is to read the contents of the input file line by line, find for each word given which lines contain the word, and print the lines with their line number to the output file. Here's my code: #include <iostream> #include <fstream> #include <string> #include <sstream> using namespace std; int main(int argc, char* argv[]) { if (argc < 4) { cerr << "Error #1: not enough arguments provided\n"; return 1; } ifstream in(argv[1]); if (!in.is_open()) { cerr << "Error #2: input file could not be opened\n"; return 2; } ofstream out(argv[2]); if (!out.is_open()) { cerr << "Error #3: output file could not be opened\n"; return 3; } ostringstream oss; for (int i = 3; i < argc; ++i) { int k = 0; string temp; oss << argv[i] << ":\n\n"; while (getline(in, temp)) { ++k; unsigned x = temp.find(argv[i]); if (x != string::npos) oss << "Line #" << k << ": " << temp << endl; } } string copy = oss.str(); out << copy; in.close(); out.close(); return 0; } If I try to run that, I get the predicted output for the first word given, but any words following it aren't found. For example, for the source code above will give the following output: in: Line #1: #include <iostream> Line #2: #include <fstream> Line #3: #include <string> Line #4: #include <sstream> Line #5: using namespace std; Line #7: int main(int argc, char* argv[]) { Line #12: ifstream in(argv[1]); Line #13: if (!in.is_open()) { Line #14: cerr << "Error #2: input file could not be opened\n"; Line #22: ostringstream oss; Line #23: string temp; Line #24: for (int i = 3; i < argc; ++i) { Line #26: int k = 0; Line #28: while (getline(in, temp)) { Line #30: unsigned x = temp.find(argv[i]); Line #31: if (x != string::npos) Line #32: oss << "Line #" << k << ": " << temp << endl; Line #35: string copy = oss.str(); Line #37: in.close(); out: That is, it'll find all the instances of the first word given but not any following. What am I doing wrong here?

  • Merging .net object graph

    - by Tiju John
    Hi guys, has anyone come across any scenario wherein you needed to merge one object with another object of same type, merging the complete object graph. for e.g. If i have a person object and one person object is having first name and other the last name, some way to merge both the objects into a single object. public class Person { public Int32 Id { get; set; } public string FirstName { get; set; } public string LastName { get; set; } } public class MyClass { //both instances refer to the same person, probably coming from different sources Person obj1 = new Person(); obj1.Id=1; obj1.FirstName = "Tiju"; Person obj2 = new Person(); ojb2.Id=1; obj2.LastName = "John"; //some way of merging both the object obj1.MergeObject(obj2); //?? //obj1.Id // = 1 //obj1.FirstName // = "Tiju" //obj1.LastName // = "John" } I had come across such type of requirement and I wrote an extension method to do the same. public static class ExtensionMethods { private const string Key = "Id"; public static IList MergeList(this IList source, IList target) { Dictionary itemData = new Dictionary(); //fill the dictionary for existing list string temp = null; foreach (object item in source) { temp = GetKeyOfRecord(item); if (!String.IsNullOrEmpty(temp)) itemData[temp] = item; } //if the same id exists, merge the object, otherwise add to the existing list. foreach (object item in target) { temp = GetKeyOfRecord(item); if (!String.IsNullOrEmpty(temp) && itemData.ContainsKey(temp)) itemData[temp].MergeObject(item); else source.Add(item); } return source; } private static string GetKeyOfRecord(object o) { string keyValue = null; Type pointType = o.GetType(); if (pointType != null) foreach (PropertyInfo propertyItem in pointType.GetProperties()) { if (propertyItem.Name == Key) { keyValue = (string)propertyItem.GetValue(o, null); } } return keyValue; } public static object MergeObject(this object source, object target) { if (source != null && target != null) { Type typeSource = source.GetType(); Type typeTarget = target.GetType(); //if both types are same, try to merge if (typeSource != null && typeTarget != null && typeSource.FullName == typeTarget.FullName) if (typeSource.IsClass && !typeSource.Namespace.Equals("System", StringComparison.InvariantCulture)) { PropertyInfo[] propertyList = typeSource.GetProperties(); for (int index = 0; index < propertyList.Length; index++) { Type tempPropertySourceValueType = null; object tempPropertySourceValue = null; Type tempPropertyTargetValueType = null; object tempPropertyTargetValue = null; //get rid of indexers if (propertyList[index].GetIndexParameters().Length == 0) { tempPropertySourceValue = propertyList[index].GetValue(source, null); tempPropertyTargetValue = propertyList[index].GetValue(target, null); } if (tempPropertySourceValue != null) tempPropertySourceValueType = tempPropertySourceValue.GetType(); if (tempPropertyTargetValue != null) tempPropertyTargetValueType = tempPropertyTargetValue.GetType(); //if the property is a list IList ilistSource = tempPropertySourceValue as IList; IList ilistTarget = tempPropertyTargetValue as IList; if (ilistSource != null || ilistTarget != null) { if (ilistSource != null) ilistSource.MergeList(ilistTarget); else propertyList[index].SetValue(source, ilistTarget, null); } //if the property is a Dto else if (tempPropertySourceValue != null || tempPropertyTargetValue != null) { if (tempPropertySourceValue != null) tempPropertySourceValue.MergeObject(tempPropertyTargetValue); else propertyList[index].SetValue(source, tempPropertyTargetValue, null); } } } } return source; } } However, this works when the source property is null, if target has it, it will copy that to source. IT can still be improved to merge when inconsistencies are there e.g. if FirstName="Tiju" and FirstName="John" Any commments appreciated. Thanks TJ

  • Strange behaviour when simply adding strings in Lazarus - FreePascal

    - by linkcharger
    The program has several "encryption" algorithms. This one should blockwise reverse the input. "He|ll|o " becomes "o |ll|He" (block length of 2). I add two strings, in this case appending the result string to the current "block" string and making that the result. When I add the result first and then the block it works fine and gives me back the original string. But when i try to reverse the order it just gives me the the last "block". Several other functions that are used for "rotation" are above. //amount of blocks function amBl(i1:integer;i2:integer):integer; begin if (i1 mod i2) <> 0 then result := (i1 div i2) else result := (i1 div i2) - 1; end; //calculation of block length function calcBl(keyStr:string):integer; var i:integer; begin result := 0; for i := 1 to Length(keyStr) do begin result := (result + ord(keyStr[i])) mod 5; result := result + 2; end; end; //desperate try to add strings function append(s1,s2:string):string; begin insert(s2,s1,Length(s1)+1); result := s1; end; function rotation(inStr,keyStr:string):string; var //array of chars -> string block,temp:string; //position in block variable posB:integer; //block length and block count variable bl, bc:integer; //null character as placeholder n : ansiChar; begin //calculating block length 2..6 bl := calcBl(keyStr); setLength(block,bl); result := ''; temp := ''; {n := #00;} for bc := 0 to amBl(Length(inStr),bl) do begin //filling block with chars starting from back of virtual block (in inStr) for posB := 1 to bl do begin block[posB] := inStr[bc * bl + posB]; {if inStr[bc * bl + posB] = ' ' then block[posB] := n;} end; //adding the block in front of the existing result string temp := result; result := block + temp; //result := append(block,temp); //result := concat(block,temp); end; end; (full code http://pastebin.com/6Uarerhk) After all the loops "result" has the right value, but in the last step (between "result := block + temp" and the "end;" of the function) "block" replaces the content of "result" with itself completely, it doesn't add result at the end anymore. And as you can see I even used a temp variable to try to work around that.. doesnt change anything though.

  • Creating an update method in a different class

    - by Sweta Dwivedi
    I have created a class called 3D model which will animate my 3D model by changing the model position according to the values based in a .txt file through a list... Since i'm using a foreach loop to read the point values when it reaches the end of the file.. XNA throws an out of bounds exception .. (which is obvious) but if i add the same code in my Game.cs update(gameTime) method.. then i dont have this problem..Any idea how to make my 3D model update work same as the update in game.cs .. Here is the code for some idea: public void patterns(GameTime gameTime) { motion_z = new List<Point3D>(); if (pattern == 1) { f = "E:/Motion_Track-output/Output1.txt"; } if (pattern == 2) { f = "E:/Motion_Track-output/cruse.txt"; } // TODO: Add your update logic here using (StreamReader r = new StreamReader(f)) { string line; //Viewport view = graphics.GraphicsDevice.Viewport; int maxWidth = view.Width; int maxHeight = view.Height; while ((line = r.ReadLine()) != null) { string[] temp = line.Split(','); int x = (int)Math.Floor(((float.Parse(temp[0]) * 0.5f) + 0.5f) * maxWidth); int y = (int)Math.Floor(((float.Parse(temp[1]) * -0.5f) + 0.5f) * maxHeight); int z = (int)Math.Floor(((float.Parse(temp[2]) / 4 * 20000))); motion_z.Add(new Point3D(x, y, z)); } modelPosition.X = (float)(motion_z[i].X); modelPosition.Y = (float)(motion_z[i].Y); modelPosition.Z = (float)(motion_z[i].Z); i++; } //Console.WriteLine("modelposX:" + modelPosition.X + "," + "motionzX:" + motion_z[i].X); }

  • Dependency Inversion Principle

    - by Chris Paine
    I have been studying also S.O.L.I.D. and watched this video: https://www.youtube.com/watch?v=huEEkx5P5Hs 01:45:30 into the video he talks about the Dependency Inversion Principle and I am scratching my head??? I had to simplify it(if possible) to get it through this thick scull of mine and here is what I came up with. Code on the marked My_modified_code my version, code marked Original DIP video version. Can I accomplish the same with the latter code? Thanks in advance. Original: namespace simple.main { class main { static void Main() { FirstClass FirstClass = new FirstClass(new OtherClass()); FirstClass.Method(); Console.ReadKey(); //tempClass temp = new OtherClass(); //temp.Method(); } } public class FirstClass { private tempClass _LastClass; public FirstClass(tempClass tempClass)//ctor { _LastClass = tempClass; } public void Method() { _LastClass.Method(); } } public abstract class tempClass{public abstract void Method();} public class LASTCLASS : tempClass { public override void Method() { Console.WriteLine("\nHello World!"); } } public class OtherClass : tempClass { public override void Method() { Console.WriteLine("\nOther World!"); } } } My_modified_code: namespace simple.main { class main { static void Main() { //FirstClass FirstClass = new FirstClass(new OtherClass()); //FirstClass.Method(); //Console.ReadKey(); tempClass temp = new OtherClass(); temp.Method(); } } //public class FirstClass //{ // private tempClass _LastClass; // public FirstClass(tempClass tempClass)//ctor // { // _LastClass = tempClass; // } // public void Method() // { // _LastClass.Method(); // } //} public abstract class tempClass{public abstract void Method();} public class LASTCLASS : tempClass { public override void Method() { Console.WriteLine("\nHello World!"); } } public class OtherClass : tempClass { public override void Method() { Console.WriteLine("\nOther World!"); } }
