  • (Possibly) Corrupted DDCrypt self-decrypting file

    - by sca
    I recently discovered some files I had encrypted and archived on a CD using DDCrypt 2.0, which is a small encryption utility from back in the day. One of its functions is to create self-decrypting files, which are essentially EXE files that you can enter a password and then have the file extracted onto your filesystem. Unfortunately, I can't seem to get them to do this properly. They appear to be decrypting and then at the last moment I get the error: Error opening encrypted file C:\users\username\Temp\dde3cfa.tmp Reason: Success and then another dialog immediately says Error extracting ddc file. I'm not really sure what this means (certainly not success), but I've checked out the temporary file and it appears to be garbage data (although of the right file size). I don't know if anyone has an idea what might be done here to extract the files, or has dealt with a similar situation before. Any ideas are appreciated! Thank you in advance for your time and any help you can provide.

  • Preventing users from deleting SQL data

    - by me2011
    We just purchased a program that requires the users to have an account in the MS SQL server, with read/write access to the program's database. My concern is that since these users will now have write access to the database, they could directly connect to the SQL server outside of the program's client and then mess with the data directly in the tables. Is there anyway I can prevent access to the database while still allowing access via the client program?

  • Database server size

    - by David
    I received a recommendation from my hosting provider noting that a general rule in production server management is to ensure that the memory on your database server is larger than the size of your total database. Our database is 1800mb (and growing) and we're being told to purchase a 2GB server. This didn't sit right with me, but I'm not an expert in production server management. We're running a MySQL db with mostly InnoDB tables and some MyISAMs. Thanks!

  • MySQL reclaim index space after large delete?

    - by cdunn
    After performing a large delete in MySQL, I understand you need to run a NULL ALTER to reclaim disk space, is this also true for reclaiming index space? We have tables using 10G of index space and have deleted/archived large chunks of this data and unsure if we need to rebuild the table in order to decrease the size of the index. Can anyone offer any advice? We are trying to avoid rebuilding the table since it would take quite awhile and lock the table. Thanks!

  • Is there a decent diagram of packet flow for a modern era (2.6+) iptables setup?

    - by stsquad
    I'm currently trying to debug a particularly hairy set of DNAT based iptables rules (the UDP reply never makes it back to the original requester) and I'm struggling to visualise the packet flow through all the numerous tables involved. So far Google'ing has shown me old 2.4 based ipchains ones. The netfilter site has some good text docs but is short on diagrams and a number of the external links are now dead. So is there a canonical diagram for iptables packet flow, preferably showing how NAT/Masqueraded packets are also dealt with?

  • PostgreSQL configuration (work_mem, effective_cache_size etc.)

    - by JohnHawkins
    :) I know I can base on tutorials that I can find on net, but there are confusing, and I know there are some of Postgres gurus here. My hardware: 2x Intel Xeon E5645 2,40 GHz / 32 GB of RAM / 2xSAS for pg_xlog (RAID1) + 3x2 SAS for rest (RAID10) + BBU and 512 MB of cache. It's gonna be used for one web project, with some big (relative term :P) tables (20mil+ of records). Server is dedicated to Posgtres service. I need help with configuring it - work_mem, effective_cache_size etc.

  • My CPU hits 100°C... Help me!

    - by JamesT
    The safe limit for processors is typically 50°C or so, but I have found that my CPU likes to do up to 100°C. I have got these readings from SpeedFan 4.42. I have a Intel Quad Core unclocked. I am using the standard intel fan with heatsink that came with the prossesor My case is a Cooler Master and I have two fans installed on the case. I took the side off to see if that helped. It lowered the temp be 3C. I don't really want to blow the processor and I don't know how to cool it down.

  • MySQL not respond when overheaded

    - by Michal Gow
    I have few Drupal 6 websites on webhosting, which causes this strange problem: some tables, especially Cache and Watchdog, tend to overhead, when overhead is bigger than some amount of kB, MySQL server is refusing connection to given Drupal database or connection is broken during query execution, Optimizing table (just overheaded rows) in phpMyAdmin is putting all back to normal. But - until database is optimized, site is showing just MySQL errors, which is ugly... Where is a problem? Thank you for any hints I could pass back to the hosting admins!

  • Find wait reason in Oracle

    - by thewolfgang
    I'm running a Java application with an Oracle 10g. I've discovered kind of a race condition that leads to an inifite long waiting time for an UPDATE statement. To solve this situation I'd like to find out what this statement is waiting for (locks on certain tables caused by statement xy etc.). I tried to use the Oracle Enterprise Manager which has found this situation as well but it doesn't tell my the reason for the wait.

  • Files apperaring/disappering from folder on share

    - by rheitzman
    Windows Server 2008 R2 I have a folder H:\temp\folderName where H: is a file share under ADS on the server. I have "Full Control" permission on the folder. I can open the folder and see a file and/or a folder that is supposed there. If I try to drag/drop or Copy/Paste the file I get an error "Could not find this item. This is no longer in ...." But I can still see the file. Similar issue occur at command prompt. I cannot delete the folder. Delete actions run w/o error but the folder is still present. I was able to rename the folder. My guess is there are some cross link issues. Or? Does anyone recognize this syndrome? What is the proper next step to verify the file share?

  • Migrating Split Access Database from one domain to another (not working, details in Q)

    - by Expo_Rob
    Some background: I'm a programmer, not a network administrator, who has been asked to migrate some accounting software (Integrated Office Accounting version 3.2) from an existing domain (OLD_NETWORK) to a new domain (NEW_NETWORK). No-body at the office knows how it works under the hood. It is a split Access 2000 database with the back-end shared and on a file server (which is also the DC) using mapped drives. The DC is NT Server 4 SP 6. The new server is server 2003. The two networks are running independently (ie: two computers on each desk). I have been able to get new computers set up on NEW_NETWORK and working with the IOA software just perfectly but for one problem: The company here uses other entirely separate databases which access the tables IOA maintains (specifically the 'customers' table) via links. To switch between these systems, you press F11 then File-Open the appropriate database and away you go (this is necessary to maintain the permissions that the IOA system uses to protect the customers table). The entire database is Access 2000, the links go to other Access databases, SQL-Server is not involved in any way, nor is a migration to SQL server likely. If I can't migrate anything over, everything will stay as it is, and the NEW_NETWORK computers will not be used. The problem: When I try and update these seperate databases (I shall call one "BANK_ACCOUNT", but the name does not matter), it says "this recordset cannot be updated". It also will sometimes not pull information out of the 'customers' table (ie: date_entered) when looking at a report of everyone who opened a bank account on a certain day (ie: today). I have tried: Giving 'everyone' full control via. shared directory permissions Giving 'everyone' full control on a file system level Checking the permissions within Access (everyone has full read/write on all tables) Copying the entire server contents from one file server to another (ie: xcopy everything) Copying the entire local client files from one computer to another, putting them in the exact same position in the file system, with the same permissons (or full control to 'everyone'). Running as an Administrator Taking one of the NEW_NETWORK computers, having it join OLD_NETWORK and run the software (direct copy from a working system with identical drive mappings), this did not work Weeping openly My Question: Is there anything else I can try? (sorry for this being so long)

  • Someone to clarify /tags and /branches in SVN (subversion)?

    - by JoeM
    I created folders /tags, /branches and /trunk on SVN server. I put initial project file into /trunk. But other folders confuses me. What should I put in /tags? I see most people do not ever use this folder. Is this like a temp folder or so? As I understood, the purpose of branches is to host a different versions. So I will have /branches/myapp_v1.0.0, /branches/myapp_v1.0.1, etc. Right? If this is true, how do I "tell" subversion tool (tortoise on windows, svn on linux) to upload project files into such and such folder?

  • Log4Net with ASP.NET MVC...nothing happens...

    - by twal
    I am trying to use log4Net with Asp.net MVC and I cannot get anything to happen with it. i created a config that is in my web project root. Here is that config file. <log4net> <root> <level value="INFO" /> <appender-ref ref="RollingLogFileAppender"/> </root> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="C:\DWSApplicationFiles\AppLogs\app.log" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="100KB" /> <staticLogFileName value="true" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t]%-5p %c [%x] - %m%n" /> </layout> </appender> <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="C:\DWSApplicationFiles\AppLogs\app.log" /> <appendToFile value="false" /> <datePattern value="-dddd" /> <rollingStyle value="Date" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t]%-5p %c [%x] - %m%n" /> </layout> </appender> </log4net> Before I am asked, yes the application has permissions to write to the directory. I use have tested this and the application has permissions to this directoy. here is where I am trying to use log4net. public class HomeController : Controller { readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); public ActionResult Index() { log.Error("In Index "); return View(); } } when I run the appliction and go to this controller. Log4net does nothing. it doesn't create the files in that directory or anything. I have enabled internal debugging for lognet and I get no output errors in the console.

  • codility challenge, test case OK , Evaluation report Wrong Answer

    - by Hussein Fawzy
    the aluminium 2014 gives me wrong answer [3 , 9 , -6 , 7 ,-3 , 9 , -6 , -10] got 25 expected 28 but when i repeated the challenge with the same code and make case test it gives me the correct answer Your test case [3, 9, -6, 7, -3, 9, -6, -10] : NO RUNTIME ERRORS (returned value: 28) what is the wrong with it ??? the challenge :- A non-empty zero-indexed array A consisting of N integers is given. A pair of integers (P, Q), such that 0 = P = Q < N, is called a slice of array A. The sum of a slice (P, Q) is the total of A[P] + A[P+1] + ... + A[Q]. The maximum sum is the maximum sum of any slice of A. For example, consider array A such that: A[0] = 3 A[1] = 2 A[2] = -6 A[3] = 3 A[4] = 1 For example (0, 1) is a slice of A that has sum A[0] + A[1] = 5. This is the maximum sum of A. You can perform a single swap operation in array A. This operation takes two indices I and J, such that 0 = I = J < N, and exchanges the values of A[I] and A[J]. To goal is to find the maximum sum you can achieve after performing a single swap. For example, after swapping elements 2 and 4, you will get the following array A: A[0] = 3 A[1] = 2 A[2] = 1 A[3] = 3 A[4] = -6 After that, (0, 3) is a slice of A that has the sum A[0] + A[1] + A[2] + A[3] = 9. This is the maximum sum of A after a single swap. Write a function: class Solution { public int solution(int[] A); } that, given a non-empty zero-indexed array A of N integers, returns the maximum sum of any slice of A after a single swap operation. For example, given: A[0] = 3 A[1] = 2 A[2] = -6 A[3] = 3 A[4] = 1 the function should return 9, as explained above. and my code is :- import java.math.*; class Solution { public int solution(int[] A) { if(A.length == 1) return A[0]; else if (A.length==2) return A[0]+A[1]; else{ int finalMaxSum = A[0]; for (int l=0 ; l<A.length ; l++){ for (int k = l+1 ; k<A.length ; k++ ){ int [] newA = A; int temp = newA[l]; newA [l] = newA[k]; newA[k]=temp; int maxSum = newA[0]; int current_max = newA[0]; for(int i = 1; i < newA.length; i++) { current_max = Math.max(A[i], current_max + newA[i]); maxSum = Math.max(maxSum, current_max); } finalMaxSum = Math.max(finalMaxSum , maxSum); } } return finalMaxSum; } } } i don't know what's the wrong with it ??

  • Delphi - threads and FindFirst function

    Hi, I'm encountering a big problem when i'm trying to make a recursive search function inside a thread (using delphi 7) bellow is the code: TParcFicDir = class(TThread) private several variables.. protected procedure Execute; override; public constructor Create(CreateSuspended: Boolean); constructor TParcFicDir.Create(CreateSuspended: Boolean); begin inherited Create(CreateSuspended); end; procedure TParcFicDir.Execute; begin try FindFiles(FStartDir,FMask);//'c:\' and '*.*' except on e:Exception do end; end; procedure TParcFicDir.FindFiles(StartDir, FileMask: string); var wTmp : string; f:TextFile; wTempSR:TSearchRec; function Search(StartDir, FileMask: string): string; var SR : TSearchRec; IsFound : Boolean; files : integer; dirs : integer; t : string; begin try files := 0; dirs := 0; if StartDir[length(StartDir)] <> '\' then StartDir := StartDir + '\'; try IsFound := (FindFirst(StartDir + '*.*', faAnyFile, SR) = 0);// here the thread gets interrupted except on e: Exception do end; while IsFound do begin if (SR.Name <> '.') and (SR.Name <> '..') then if ((SR.Attr and faDirectory) <> 0) then if FScanDirs then begin inc(dirs); t := Search(StartDir + SR.Name, FileMask); try files := files + strtoint(copy((t), 0, pos('#', t) - 1));//old code, don't take on calcul; Delete(t, 1, pos('#', t)); dirs := dirs + strtoint(t); except on e: Exception do end; begin t := StartDir + SR.Name; wTmp := t; wtmp := ''; Inc(FDirNo); writeln(f,t); inc(filno); end; end else if ScanFiles then begin inc(filno); inc(files); end; IsFound := FindNext(SR) = 0; end; Result := IntToStr(files) + '#' + IntToStr(dirs); sysutils.FindClose(SR); except on e: Exception do end; end; begin filno := 0; try try if trim(FPathFileTmp)<>'' then AssignFile(f, FPathFileTmp+'Temp.bak') else AssignFile(f,ExtractFileDir(GetDllName)+'\Temp.bak'); Rewrite(f); Search(StartDir, FileMask); if StartDir[length(StartDir)] = '\' then delete(StartDir, length(StartDir), 1); wTmp := StartDir; wTmp := ''; if FindFirst(StartDir, faDirectory, wTempSR) = 0 then writeln(f); writeln(f); CloseFile(f); except on e: Exception do end; finally end; end; ok, probably the code is a little messed up, but i don't understand why the thread ends at 'findfirst' part....i googled it, no results. any help will be appreciated!

  • ASP.NET MVC 2 "value" in DataAnnotation attribute passed is null, when incorrect date is submitted.

    - by goldenelf2
    Hello to all! This is my first question here on stack overflow. i need help on a problem i encountered during an ASP.NET MVC2 project i am currently working on. I should note that I'm relatively new to MVC design, so pls bear my ignorance. Here goes : I have a regular form on which various details about a person are shown. One of them is "Date of Birth". My view is like this <div class="form-items"> <%: Html.Label("DateOfBirth", "Date of Birth:") %> <%: Html.EditorFor(m => m.DateOfBirth) %> <%: Html.ValidationMessageFor(m => m.DateOfBirth) %> </div> I'm using an editor template i found, to show only the date correctly : <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime?>"%> <%= Html.TextBox("", (Model.HasValue ? Model.Value.ToShortDateString() : string.Empty))%> I used LinqToSql designer to create my model from an sql database. In order to do some validation i made a partial class Person to extend the one created by the designer (under the same namespace) : [MetadataType(typeof(IPerson))] public partial class Person : IPerson { //To create buddy class } public interface IPerson { [Required(ErrorMessage="Please enter a name")] string Name { get; set; } [Required(ErrorMessage="Please enter a surname")] string Surname { get; set; } [Birthday] DateTime? DateOfBirth { get; set; } [Email(ErrorMessage="Please enter a valid email")] string Email { get; set; } } I want to make sure that a correct date is entered. So i created a custom DataAnnotation attribute in order to validate the date : public class BirthdayAttribute : ValidationAttribute { private const string _errorMessage = "Please enter a valid date"; public BirthdayAttribute() : base(_errorMessage) { } public override bool IsValid(object value) { if (value == null) { return true; } DateTime temp; bool result = DateTime.TryParse(value.ToString(), out temp); return result; } } Well, my problem is this. Once i enter an incorrect date in the DateOfBirth field then no custom message is displayed even if use the attribute like [Birthday(ErrorMessage=".....")]. The message displayed is the one returned from the db ie "The value '32/4/1967' is not valid for DateOfBirth.". I tried to enter some break points around the code, and found out that the "value" in attribute is always null when the date is incorrect, but always gets a value if the date is in correct format. The same ( value == null) is passed also in the code generated by the designer. This thing is driving me nuts. Please can anyone help me deal with this? Also if someone can tell me where exactly is the point of entry from the view to the database. Is it related to the model binder? because i wanted to check exactly what value is passed once i press the "submit" button. Thank you.

The same ( value == null) is passed also in the code generated by the designer. This thing is driving me nuts. Please can anyone help me deal with this? Also if someone can tell me where exactly is the point of entry from the view to the database. Is it related to the model binder? because i wanted to check exactly what value is passed once i press the "submit" button. Thank you.

  • EF4 generates invalid script

    - by Jaxidian
    When I right-click in a .EDMX file and click Generate Database From Model, the resulting script is obviously wrong because of the table names. What it generates is the following script. Note the table names in the DROP TABLE part versus the CREATE TABLE part. Why is this inconsistent? This is obviously not a reusable script. What I created was an Entity named "Address" and an Entity named "Company", etc (all singular). The EntitySet names are pluralized. The "Pluralize New Objects" boolean does not change this either. So what's the deal? For what it's worth, I originally generated the EDMX by pointing it to a database that had tables with non-pluralized names and now that I've made some changes, I want to go back the other way. I'd like to have the option to go back and forth as neither the db-first nor the model-first model is ideal in all scenarios, and I have the control to ensure that there will be no merging issues from multiple people going both ways at the same time. -- -------------------------------------------------- -- Dropping existing FOREIGN KEY constraints -- NOTE: if the constraint does not exist, an ignorable error will be reported. -- -------------------------------------------------- ALTER TABLE [Address] DROP CONSTRAINT [FK_Address_StateID-State_ID];

  • Updating a Data Source with a Dataset

    - by Paul
    Hi, I need advice. I have asp.net web service and winforms client app. Client call this web method and get dataset. 1. [WebMethod] 2. public DataSet GetSecureDataSet(string id) 3. { 4. 5. 6. SqlConnection conn = null; 7. SqlDataAdapter da = null; 8. DataSet ds; 9. try 10. { 11. 12. string sql = "SELECT * FROM Tab1"; 13. 14. string connStr = WebConfigurationManager.ConnectionStrings["Employees"].ConnectionString; 15. 16. conn = new SqlConnection(connStr); 17. conn.Open(); 18. 19. da = new SqlDataAdapter(sql, conn); 20. 21. ds = new DataSet(); 22. da.Fill(ds, "Tab1"); 23. 24. return ds; 25. } 26. catch (Exception ex) 27. { 28. throw ex; 29. } 30. finally 31. { 32. if (conn != null) 33. conn.Close(); 34. if (da != null) 35. da.Dispose(); 36. } 37. } After he finish work he call this update web method. He can add, delete and edit rows in table in dataset.

  • Template problems: No matching function for call

    - by Nick Sweet
    I'm trying to create a template class, and when I define a non-member template function, I get the "No matching function for call to randvec()" error. I have a template class defined as: template <class T> class Vector { T x, y, z; public: //constructors Vector(); Vector(const T& x, const T& y, const T& z); Vector(const Vector& u); //accessors T getx() const; T gety() const; T getz() const; //mutators void setx(const T& x); void sety(const T& y); void setz(const T& z); //operations void operator-(); Vector plus(const Vector& v); Vector minus(const Vector& v); Vector cross(const Vector& v); T dot(const Vector& v); void times(const T& s); T length() const; //Vector<T>& randvec(); //operators Vector& operator=(const Vector& rhs); friend std::ostream& operator<< <T>(std::ostream&, const Vector<T>&); }; and the function in question, which I've defined after all those functions above, is: //random Vector template <class T> Vector<double>& randvec() { const int min=-10, max=10; Vector<double>* r = new Vector<double>; int randx, randy, randz, temp; const int bucket_size = RAND_MAX/(max-min +1); temp = rand(); //voodoo hackery do randx = (rand()/bucket_size)+min; while (randx < min || randx > max); r->setx(randx); do randy = (rand()/bucket_size)+min; while (randy < min || randy > max); r->sety(randy); do randz = (rand()/bucket_size)+min; while (randz < min || randz > max); r->setz(randz); return *r; } Yet, every time I call it in my main function using a line like: Vector<double> a(randvec()); I get that error. However, if I remove the template and define it using 'double' instead of 'T', the call to randvec() works perfectly. Why doesn't it recognize randvec()? P.S. Don't mind the bit labeled voodoo hackery - this is just a cheap hack so that I can get around another problem I encountered.

  • Resolve naming conflict in included XSDs for JAXB compilation

    - by Jason Faust
    I am currently trying to compile with JAXB (IBM build 2.1.3) a pair of schema files into the same package. Each will compile on it's own, but when trying to compile them together i get a element naming conflict due to includes. My question is; is there a way to specify with an external binding a resolution to the naming collision. Example files follow. In the example the offending element is called "Common", which is defined in both incA and incB: incA.xsd <?xml version="1.0" encoding="UTF-8"?> <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.org/" xmlns:tns="http://www.example.org/" elementFormDefault="qualified"> <complexType name="TypeA"> <sequence> <element name="ElementA" type="string"></element> </sequence> </complexType> <!-- Conflicting element --> <element name="Common" type="tns:TypeA"></element> </schema> incB.xsd <?xml version="1.0" encoding="UTF-8"?> <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.org/" xmlns:tns="http://www.example.org/" elementFormDefault="qualified"> <complexType name="TypeB"> <sequence> <element name="ElementB" type="int"></element> </sequence> </complexType> <!-- Conflicting element --> <element name="Common" type="tns:TypeB"></element> </schema> A.xsd <?xml version="1.0" encoding="UTF-8"?> <schema targetNamespace="http://www.example.org/" elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://www.example.org/"> <include schemaLocation="incA.xsd"></include> <complexType name="A"> <sequence> <element ref="tns:Common"></element> </sequence> </complexType> </schema> B.xsd <?xml version="1.0" encoding="UTF-8"?> <schema targetNamespace="http://www.example.org/" elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://www.example.org/"> <include schemaLocation="incB.xsd"></include> <complexType name="B"> <sequence> <element ref="tns:Common"></element> </sequence> </complexType> </schema> Compiler error when both are compiled from one evocation of xjb: [ERROR] 'Common' is already defined line 9 of file:/C:/temp/incB.xsd [ERROR] (related to above error) the first definition appears here line 9 of file:/C:/temp/incA.xsd (For reference, this is a generalization to resolve an issue with compiling the OAGIS8 SP3 package)

  • 3-way quicksort, question
