  • Source cross reference like LXR but written in PHP?

    - by Dan
    Hi, does someone know a good cross reference engine like LXR, but written in PHP? My provider has PHP and MySQL as well as Postgres DBs, but neither I have access to Perl nor via SSH. I'd like to put up a online cross ref for my Software which is written in C. Thanks for helping! Dan

  • Are reference attributes destroyed when class is destroyed in C++?

    - by Genba
    Suppose I have a C++ class with an attribute that is a reference: class ClassB { ClassA &ref; public: ClassB(ClassA &_ref); } Of course, the constructor is defined this way: ClassB::ClassB(ClassA &_ref) : ref(_ref) { /* ... */ } My question is: When an instance of class 'ClassB' is destroyed, is the object referenced by 'ClassB::ref' also destroyed?

  • Does binding temporary to a reference require a copy constructor in C++?

    - by vitaut
    Consider the following code: class A { A(const A&); public: A() {} }; int main() { const A &a = A(); } This code compiles fine with GCC, but fails to compile with Visual C++ with the following error: test.cc(8) : error C2248: 'A::A' : cannot access private member declared in class 'A' test.cc(2) : see declaration of 'A::A' test.cc(1) : see declaration of 'A' So is it necessary to have a copy constructor accessible when binding a temporary to a reference?

  • Dynamically reference a Named Table Column via cell content in Excel

    - by rcphq
    How do I reference an Excel Table column dynamically in Excel 2007? ie: i wanna reference a named column of a named table and what table it is will vary with the value of a cell. I have a Table in Excel (Let's call it Table1). I want to reference one of its columns (Let's call it column1) dynamically from a value in another cell (A1) so that I can achieve the following result: When I change A1, the formula that counts Table1[DynamicallyReferencedColumnName] gets updated to the new reference. I tried using =Count(Table1[INDIRECT("$A$1")]) but Excel says the formula contains an error. Example: A1 = names then the formula would equal Count(Table1[names]). A1 = lastname then the formula would equal Count(Table1[lastname]).

  • For Loop counting from 1 to n in a windows bat script

    - by raoulsson
    I need to run a windows command n times within a bat script file. I know how to do this in various programming languages but cannot manage to get it right on the windows command line :-( I would expect something like either for(int i = 0; i < 100; i++) { // do something } or even this (though not entirely seriously) 1.upto(100, { // do something }) Thanks! EDIT I can write a program in java, perl, c or whatever that will generate a bat script that looks like this for %%N in (1 2 3 4 5 6 7 8 9 10 11 12) do echo %%N and so on. Or even "better": echo 1 echo 2 echo 3 echo 4 echo 5 echo 6 echo 7 echo 8 echo 9 echo 10 echo 11 echo 12 and then execute it... But the thing is that I need a concise way to specify a range of numbers to iterate through within the script. Thanks!

  • Hard Disk Not Counting Reallocated Sectors

    - by MetaNova
    I have a drive that is reporting that the current pending sectors is "45". I have used badblocks to identify the sectors and I have been trying to write zeros to them with dd. From what I understand, when I attempt writing data directly to the bad sectors, it should trigger a reallocation, reducing current pending sectors by one and increasing the reallocated sector count. However, on this disk both Reallocated_Sector_Ct and Reallocated_Event_Count raw values are 0, and dd fails with I/O errors when I attempt to write zeros to the bad sectors. dd works fine, however, when I write to a good sector. # dd if=/dev/zero of=/dev/sdb bs=512 count=1 seek=217152 dd: error writing ‘/dev/sdb’: Input/output error Does this mean that my drive, in some way, has no spare sectors to be used for reallocation? Is my drive just in general a terrible person? (The drive isn't actually mine, I'm helping a friend out. They might have just gotten a cheap drive or something.) In case it is relevant, here is the output of smartctl -i : Model Family: Western Digital Caviar Green (AF) Device Model: WDC WD15EARS-00Z5B1 Serial Number: WD-WMAVU3027748 LU WWN Device Id: 5 0014ee 25998d213 Firmware Version: 80.00A80 User Capacity: 1,500,301,910,016 bytes [1.50 TB] Sector Size: 512 bytes logical/physical Device is: In smartctl database [for details use: -P show] ATA Version is: ATA8-ACS (minor revision not indicated) SATA Version is: SATA 2.6, 3.0 Gb/s Local Time is: Fri Oct 18 17:47:29 2013 CDT SMART support is: Available - device has SMART capability. SMART support is: Enabled UPDATE: I have run shred on the disk, which has caused Current_Pending_Sector to go to zero. However, Reallocated_Sector_Ct and Reallocated_Event_Count are still zero, and dd is now able to write data to the sectors it was previously unable to. This leads me with several other questions: Why aren't the reallocations being recored by the disk? I'm assuming the reallocation took place as I can now write data directly to the sector and couldn't before. Why did shred cause reallocation and not dd? Does the fact that shred writes random data instead of just zeros make a difference?

  • Highlighting duplicate column-pair and counting the rows Excel

    - by pleasehelpme
    Given the data below, the column-pair with the same values for at least 4 consecutive rows should be highlighted. image here for better visualization: http://i49.tinypic.com/2jeshtt.jpg 2 2 3 4 3 4 3 4 3 4 2 3 1 2 2 2 3 3 3 3 3 3 3 3 2 3 2 3 2 3 2 3 2 2 3 4 3 4 3 4 3 4 3 4 The output should be something like this, where the column-pair values that are the same for at least 4 consecutive rows are highlighted. image here for better visualization: http://i48.tinypic.com/i2lzc8.jpg 2 2 3 4 3 4 3 4 3 4 2 3 1 2 2 2 3 3 3 3 3 3 3 3 2 3 2 3 2 3 2 3 2 2 3 4 3 4 3 4 3 4 3 4 Then, I need to know the number of instances of the N-consecutive equal column-pair. Considering the data above, N=4 should be 3 and N=5 should be 1, where N is the number of rows that the column-pair is consecutively equal.

  • Resize2fs at 81h and counting

    - by Adam
    Setup: 12x 1TB drives in a RAID6 (MDADM) crypt-setup running ontop of MDADM LVM running on the crypted drives EXT4 on the LVM Background: I added a new drive to the RAID (increasing from 11 to 12 drives), and 'bubbled' up through the layers (MDADM, etc...) to reizing the ext4 partition. This machine is used as a centralized repository for photography and as a backup server (for both Windows and Mac machines) so bringing it down to add the drive and wait for the resizing and everything wasn't really an option. So I started the resize operation several days ago. HTOP is reporting the resize2fs operation as running for 81h now. DMESG and syslog are both clear, and the drives are still accessable. The resize command reports it's started an online resize of the partition, so the process IS running, and it is burning through 100% of one of my cores. Question: Is it normal for the operation to take this long or has something gone horribly wrong? Where would I start looking for signs of trouble?

  • ILMerge - Unresolved assembly reference not allowed: System.Core

    - by Steve Michelotti
    ILMerge is a utility which allows you the merge multiple .NET assemblies into a single binary assembly more for convenient distribution. Recently we ran into problems when attempting to use ILMerge on a .NET 4 project. We received the error message: An exception occurred during merging: Unresolved assembly reference not allowed: System.Core.     at System.Compiler.Ir2md.GetAssemblyRefIndex(AssemblyNode assembly)     at System.Compiler.Ir2md.GetTypeRefIndex(TypeNode type)     at System.Compiler.Ir2md.VisitReferencedType(TypeNode type)     at System.Compiler.Ir2md.GetMemberRefIndex(Member m)     at System.Compiler.Ir2md.PopulateCustomAttributeTable()     at System.Compiler.Ir2md.SetupMetadataWriter(String debugSymbolsLocation)     at System.Compiler.Ir2md.WritePE(Module module, String debugSymbolsLocation, BinaryWriter writer)     at System.Compiler.Writer.WritePE(String location, Boolean writeDebugSymbols, Module module, Boolean delaySign, String keyFileName, String keyName)     at System.Compiler.Writer.WritePE(CompilerParameters compilerParameters, Module module)     at ILMerging.ILMerge.Merge()     at ILMerging.ILMerge.Main(String[] args) It turns out that this issue is caused by ILMerge.exe not being able to find the .NET 4 framework by default. The answer was ultimately found here. You either have to use the /lib option to point to your .NET 4 framework directory (e.g., “C:\Windows\Microsoft.NET\Framework\v4.0.30319” or “C:\Windows\Microsoft.NET\Framework64\v4.0.30319”) or just use an ILMerge.exe.config file that looks like this: 1: <configuration> 2: <startup useLegacyV2RuntimeActivationPolicy="true"> 3: <requiredRuntime safemode="true" imageVersion="v4.0.30319" version="v4.0.30319"/> 4: </startup> 5: </configuration> This was able to successfully resolve my issue.

  • BizTalk Pipeline Component Error: "Object reference not set to an instance of an object"

    - by Stuart Brierley
    Yesterday I posted about my BizTalk Archiving Pipeline Component, which can be found on Codeplex if anyone is interested in taking a look. During testing of this component I began to encounter an error whereby the component would throw an "Object reference not set to an instance of an object" error when processing as a part of a Custom Pipeline. This was occurring when the component was reading a ReadOnlySeekableStream so that the data can be archived to file, but the actual code throwing the error was somewhere in the depths of the Microsoft.BizTalk.Streaming stack. It turns out that there is a known issue where this exception can be thrown because the garbage collector has disposed of of the stream before execution of the custom pipeline has completed. To get around this you need to add the streams in your code to the pipeline context resource tracker.   So a block of my code goes from:                         originalStrm = bodyPart.GetOriginalDataStream();                         if (!originalStrm.CanSeek)                         {                             ReadOnlySeekableStream seekableStream = new ReadOnlySeekableStream(originalStrm);                             inmsg.BodyPart.Data = seekableStream;                             originalStrm = inmsg.BodyPart.Data;                         }                         fileArchive = new FileStream(FullPath, FileMode.Create, FileAccess.Write);                         binWriter = new BinaryWriter(fileArchive);                         byte[] buffer = new byte[bufferSize];                         int sizeRead = 0;                         while ((sizeRead = originalStrm.Read(buffer, 0, bufferSize)) != 0)                         {                             binWriter.Write(buffer, 0, sizeRead);                         } to                         originalStrm = bodyPart.GetOriginalDataStream();                         if (!originalStrm.CanSeek)                         {                             ReadOnlySeekableStream seekableStream = new ReadOnlySeekableStream(originalStrm);                             inmsg.BodyPart.Data = seekableStream;                             originalStrm = inmsg.BodyPart.Data;                         }                         pc.ResourceTracker.AddResource(originalStrm);                         fileArchive = new FileStream(FullPath, FileMode.Create, FileAccess.Write);                         binWriter = new BinaryWriter(fileArchive);                         byte[] buffer = new byte[bufferSize];                         int sizeRead = 0;                         while ((sizeRead = originalStrm.Read(buffer, 0, bufferSize)) != 0)                         {                             binWriter.Write(buffer, 0, sizeRead);                         } So far this seems to have solved the issue, the error is no more, and my archive component is continuing its way through testing.

  • Comparing the Performance of Visual Studio's Web Reference to a Custom Class

    As developers, we all make assumptions when programming. Perhaps the biggest assumption we make is that those libraries and tools that ship with the .NET Framework are the best way to accomplish a given task. For example, most developers assume that using ASP.NET's Membership system is the best way to manage user accounts in a website (rather than rolling your own user account store). Similarly, creating a Web Reference to communicate with a web service generates markup that auto-creates a proxy class, which handles the low-level details of invoking the web service, serializing parameters, and so on. Recently a client made us question one of our fundamental assumptions about the .NET Framework and Web Services by asking, "Why should we use proxy class created by Visual Studio to connect to a web service?" In this particular project we were calling a web service to retrieve data, which was then sorted, formatted slightly and displayed in a web page. The client hypothesized that it would be more efficient to invoke the web service directly via the HttpWebRequest class, retrieve the XML output, populate an XmlDocument object, then use XSLT to output the result to HTML. Surely that would be faster than using Visual Studio's auto-generated proxy class, right? Prior to this request, we had never considered rolling our own proxy class; we had always taken advantage of the proxy classes Visual Studio auto-generated for us. Could these auto-generated proxy classes be inefficient? Would retrieving and parsing the web service's XML directly be more efficient? The only way to know for sure was to test my client's hypothesis. Read More >

  • KeyRef &ndash; A Keyboard Shortcut Reference Site

    - by Liam McLennan
    The mouse is like computer training wheels. It makes using a computer easier – but it slows you down. Like many of my peers I am making a effort to learn keyboard shortcuts to reduce my dependence on the mouse. So I have started accumulating browser bookmarks to websites listing keyboard shortcuts for vim and resharper etc. Based on the assumption that I am not the only person who finds this untenable I am considering building the ultimate keyboard shortcut reference site. This is an opportunity for me to improve my rails skills and hopefully contribute something useful to the anti-mouse community. Mockups Shortcuts will be grouped by application, so the first thing a user needs to do is find their application. They do this by typing the application name into a textbox and then selecting from a reducing list of applications. This interface will work like the stackoverflow tags page. Selecting an application will take the user to a page that lists the shortcuts for that application. This page will have a permalink for bookmarking. Shortcuts can be searched by keyword or by using the shortcut.
