  • Collapsing rows of duplicate dates in a column leaving one row with a subtotal?

    - by Will
    I have several thousand rows of date, time, and values in columns. Each row is contains a date, time for that date, and a value for that time period (hour) So each 24 rows has the same date with each having the next hour of the day. I'd like to collapse or group the 24 rows leaving the last row with a subtotal of the value (column D) to the right in column F. While this can obviously be done manually, several years of data would take a while and there ought to be a way to do this other wise?

    - by jack
    we have a .net framework application with a vc dll and a vc ocx, and now if we only import one dll ,it is ok, but when we import both, it will pop a messagebox saying: Debug Assertion Failed! and i studied the child module of our application that import the vc dll, i found after the framework import vc ocx and initialize , then the function LoadLibrary in our module importing the vc dll would return 0, that means memory limited or call improperly, i use getlasterror() the error code is 1114. so it is very frustrated ,hope someone can help me.

  • Why use one dimensional array instead of a two dimensional arrray?

    - by user3869145
    I was doing some work handling a lot of information and my partner told me that I was using too many matrices to manipulate the variables of the problem. The idea was to use one dimension arrays int a[] instead of the 2 dimensional arrays int b[][], to save memory and processing speed of the algorithm. How certain is that this change will accelerate the speed of execution or compilation of my code in c ++?

  • What to do if one library is not multi-threaded ?

    - by LB
    Hi, I would like to multi-thread an application, however one library i'm using is not multi-thread capable (i don't know what's the right word ? synchronized ?). What are my options ? As far as i know there's nothing in between threads and processes (Runtime.exec) in java (no abstraction in the jvm to have something like an isolated "java process"). How would you deal with that ?

  • IIS7 Failure after installing Advanced Logging

    - by Guy Harwood
    I came across a nasty issue when i installed the Advanced Logging feature for IIS7 via the Web Platform Installer on my Windows 2008 Server.  Basically, after installation and reboot none of my sites were working and returned 503 – Internal Server Error. Snooping around in the Event Viewer i found the following error reported by the W3SVC… The Module DLL C:\Program Files\IIS\Advanced Logging\AdvancedLoggingModule.dll failed to load. The data is the error Even though the DLLs are there, it is not picking them up. I managed to find a fix via google that involves editing the configapplicationHost.config file in the C:\Windows\System32\inetsrv\ directory. 1.  Copy AdvancedLoggingModule.dll and ClientLoggingHandler.dll to %windir%\system32 (C:\windows\system32  on a default setup) 2.  Locate the file C:\Windows\System32\inetsrv\configapplicationHost.config and make a backup, then open it in a text editor (i recommend Notepad++). 3.  Search for the following 2 lines (mine are located on line 570).. <add name="ClientLoggingHandler" image="%ProgramFiles%\IIS\Advanced Logging\ClientLoggingHandler.dll" /> <add name="AdvancedLoggingModule" image="%ProgramFiles%\IIS\Advanced Logging\AdvancedLoggingModule.dll" /> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } and alter them to…. <add name="ClientLoggingHandler" image="%windir%\system32\ClientLoggingHandler.dll" /> <add name="AdvancedLoggingModule" image="%windir%\system32\AdvancedLoggingModule.dll" /> 4. Open a command prompt and run iisReset. 5. All sites should now be working. .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }

  • TinyFluidGrid – a clean and lightweight css framework

    - by Guy Harwood
    I've been using the 960 Grid system for a while on some of my personal projects and if like me you are no css ninja its convenient for sidestepping the usual nightmare of a good cross browser layout, and allows you to move on to the nitty gritty code and functionality. I just stumbled across a new layout generator that looks rather snazzy and has the functionality to back it up.  TinyFluidGrid generates exactly that – a tiny fluid grid! Worth a look.

  • Application Lifecycle Management with Visual Studio 2010 – Wrox Book

    - by Guy Harwood
    After running with a somewhat disconnected set of tools (vs 2008, Ontime, sharepoint 2007) for managing our projects we decided to make the move to Team Foundation Server 2010.  With limited coverage of the product available online i went in search of a book and found this… View this book on the Wrox website I must point out that i have only read 10 of the 26 chapters so far, mainly the ones that cover source code control, work item tracking and database projects.  This enables our dev team to get familiar with it before switching project management over at a future date. Needless to say i am very impressed with the detail it provides, answering pretty much every question i had about TFS so far.  I'm looking forward to digging into the sections on testing, code analysis and architecture. Highly recommended.

  • Windows Server 2003 seems to pick the 'outgoing' IP address at random from all the ones configured in IIS, how can I make it just use one?

    - by Ryan
    We have multiple sites in IIS with different IP addresses. This is cool, want different IPs to all go to this server and use the proper site. However I discovered an issue that when the server makes an outgoing connection, I cannot predict which IP it will use. I had to have one client add ALL the IPs to their firewall so that a certain service could communicate with their server. Well now the time has come to add another IP/site to IIS but I had told them they would not need to add any more IPs. So the question is, how can I make Windows Server 2003 use only ONE specific IP for outgoing calls instead of it being unpredictable? If this is not a good enough description, when I was RDPed into the server and I opened IE and went to 'what is my IP' it was sometimes different which is how I discovered why the one client's firewall was suddenly refusing the connections. How can I just make outgoing calls originate from a static IP yet still allow multiple IPs pointing to different sites in IIS?

  • using cin and cout in textmate [migrated]

    - by That Guy
    I am usually a Java programmer, and have used textmate for that almost exclusively, but lately I started using C++ with it. but when i use even the most basic programs and incorporate the cin keyword, and run the program, I dont get an oppurtunity to put in anything during runtime and sometimes it inserts random values by itself! for example, if i ran this in textmate: #include <iostream> int stonetolb(int); int main() { using namespace std; int stone; cout << "enter the weight in stone"; cin >> stone; int pounds = stonetolb(stone); cout << stone << "stone = "; cout << pounds <<" pounds."; return 0; } int stonetolb(int sts) { return 14 * sts; } I would come out with the output: enter the weight in stone32767stone = 458738 pounds. Why is this happening, and how do I stop it?

  • How to make custom shaped holes in terrain

    - by Guy Ben-Moshe
    So I'm trying to create a game where you fit certain shaped objects into the hole that fits them (similar to the young children's game with different shaped blocks) in Unity 3D. I've encountered a problem, how do I make the holes in the terrain? Or what type of object should I use for making holes in? So far I've tried to make a 3d model in unity by using other cubes and planes, it just doesn't feel right. I guess I need to create a model in another software and import to unity, I don't know any other software I can use. Tips would help.

  • Screen Corruption in half the screen only

    - by Guy DAmico
    About 50% of the my NATTY desktop screen is corrupted. Once that happens I can re-boot as many times as I want but the problem continues. If I logout and then into WINDOWS for a day I may be successful and boot UBUNTU with a good screen. The desktop is formatted correctly, there's no pixelation, rather there is a fine grained white crosshatch pattern covering the entire screen. If I open any application the screen corruption worsens eventually to the point I can no longer make out anything. I ran ram memory test w/o any errors. I have no display issues when running WINDOWS 7. Any ideas. My computer is a Dual Boot stock DELL 5150 w/3gig of ram an on board video.

  • C# creating a simple snake game

    - by Guy David
    I was thinking about creating a snake game with C#, so I ran ideas in my head, and some problems came up. How can I track and output in the correct location the blocks that run after the snake's head? If the snake is built of five blocks, and the user starts going in a circle, how can I print the snake body in the right location? Also, how can I create an action that will run on the background, which will move the snake forward, no matter what the user does? What structure should my code have? (code design structure) This should be a console application, since it's the only framework I am familiar with. I am not looking for finished code, since I want to really understand how it should work.

  • Getting paid through Ltd or Umbrella company?

    - by Guy
    I am working for a company as a web dev consultant at the moment, and they asked me whether I want to get payed through the Umbrella company or through my Ltd. Which is better for me and why? The @David Thornley made a good point in comments. Don't forget that we are talking about web developing here. I am not sure how is it in UK, but in the country I am from, you get taxed differently for the stuff you do.

  • Camera movement and threshold not working

    - by irish guy mcconagheh
    I have a platformer that is in progress, part of this has a camera which I only want to move when the character moves out of a certain threshold, to try to accomplish this I have the following if statement: if(((Mathf.Abs(target.transform.position.x))-(Mathf.Abs(transform.position.x)))>thres){ x = moveTo(transform.position.x, target.position.x, trackSpeed); } in unity/c#. In pseudocode it means if((absolute value of player x) - (absolute value of camera x) is greater than the threshold){ move { however this does not seem to work correctly. it appears to work for the first couple of times the threshold is reached, however the distance between the camera and the player has to increase every time for the camera to move. I do not believe the movement of the camera is the problem, however the code for it is as follows: private float moveTo(float n, float target, float accel) { if (n == target) { return n; } else { float dir = Mathf.Sign(target - n); n += accel * Time.deltaTime * dir; return (dir == Mathf.Sign(target-n))? n: target; } } }
