  • Bulletproof way to DROP and CREATE a database under Continuous Integration.

    - by H. Abraham Chavez
    I am attempting to drop and recreate a database from my CI setup. But I'm finding it difficult to automate the dropping and creation of the database, which is to be expected given the complexities of the db being in use. Sometimes the process hangs, errors out with "db is currently in use" or just takes too long. I don't care if the db is in use, I want to kill it and create it again. Does some one have a straight shot method to do this? alternatively does anyone have experience dropping all objects in the db instead of dropping the db itself? USE master --Create a database IF EXISTS(SELECT name FROM sys.databases WHERE name = 'mydb') BEGIN ALTER DATABASE mydb SET SINGLE_USER --or RESTRICTED_USER --WITH ROLLBACK IMMEDIATE DROP DATABASE uAbraham_MapSifterAuthority END CREATE DATABASE mydb;

  • How to access a structure member in a function that get it as void* type?

    - by Ahmad
    I want to have a function that accepts different type of structures as argument. So, since I don't have a specific type, I have to use void*. Now question is: when I pass a structure to this function, how can I access a known member of this structure inside the function? Specifically, I know that all structures have str1 as a member and I want, for example, print it. Here is a sample code: struct { char* str1; float tt1; } var1 = {"This is me", 12}; struct { char* str1; int tt2; } var2 = {"This is you", 18}; void printStruct(void* str) { printf("\n the structure string is %s", ??); //can I put something in ?? to print the string? } main(....) { printStruct(&var1); printStruct(&var2); }

  • How do I create a LiveUSB that lets me install any Ubuntu version?

    - by Dariopnc
    What I'd like to do: have Ubuntu installed on a USB drive and from there install any ubuntu version on a hdd. This is kinda different from using usb-creator because I'd like to have a persistent ubuntu install on the USB drive and not upgrade it every 6 months. From there I'd like to be able to install the most recent ubuntu version. I think it's just a matter of configuring ubiquity, but don't know if this is the case and how exactly do this. EDIT: Let's clarify the persistent thing: suppose I have my USB with ubuntu precise on it suppose quantal is out in the wild suppose that I want to install quantal on the hdd of a computer suppose that I want/can use only the USB drive with precise on it I should erase/upgrade precise on the USB drive to quantal and then install it on the hard drive I don't want to touch my ubuntu install on the USB drive, I'd like to be able to install the newer ubuntu version (quantal) on a hdd from another one (precise) on a USB drive I'd better avoid upgrading the installation on the hdd Hope this helps

  • How can I create a flexible system for tiling a 2D RPG map?

    - by CptSupermrkt
    Using libgdx here. I've just finished learning some of the basics of creating a 2D environment and using an OrthographicCamera to view it. The tutorials I went through, however, hardcoded their tiled map in, and none made mention of how to do it any other way. By tiled map, I mean like Final Fantasy 1, where the world map is a grid of squares, each with a different texture. So for example, I've got a 6 tile x 6 tile map, using the following code: Array<Tile> tiles = new Array<Tile>(); tiles.add(new Tile(new Vector2(0,5), TileType.FOREST)); tiles.add(new Tile(new Vector2(1,5), TileType.FOREST)); tiles.add(new Tile(new Vector2(2,5), TileType.FOREST)); tiles.add(new Tile(new Vector2(3,5), TileType.GRASS)); tiles.add(new Tile(new Vector2(4,5), TileType.STONE)); tiles.add(new Tile(new Vector2(5,5), TileType.STONE)); //... x5 more times. Given the random nature of the environment, for loops don't really help as I have to start and finish a loop before I was able to do enough to make it worth setting up the loop. I can see how a loop might be helpful for like tiling an ocean or something, but not in the above case. The above code DOES get me my final desired output, however, if I were to decide I wanted to move a piece or swap two pieces out, oh boy, what a nightmare, even with just a 6x6 test piece, much less a 1000x1000 world map. There must be a better way of doing this. Someone on some post somewhere (can't find it now, of course) said to check out MapEditor. Looks legit. The question is, if that is the answer, how can I make something in MapEditor and have the output map plug in to a variable in my code? I need the tiles as objects in my code, because for example, I determine whether or not a tile is can be passed through or collided with based on my TileTyle enum variable. Are there alternative/language "native" (i.e. not using an outside tool) methods to doing this?

  • How do I create a SQL Server 2008 Reporting Services Template to a Default Font?

    - by David Stein
    I'm creating a new template to create reports from at a later date. I know how to create one, and I know where to save it. However, the problem is this. Everything that is created on the report uses the default font of Arial with a size of 10pt. I need to set mine to default to Tahoma 11pt. I can create a mock title, mock tables, etc and save those to Tahoma 11pt, but any new controls that are used on any version of this report will default back to Arial 10pt. How do I fix this?

  • Why do most programming languages only support returning a single value from a function?

    - by M4N
    Is there a reason or an explanation why functions in most(?) programming languages are designed to support any number of input parameters but only one return value? In most languages, it is possible to "work around" that limitation, e.g. by using out-parameters, returning pointers or by defining/returning structs/classes. But it seems strange, that programming languages were not designed to support multiple return values in a more "natural" way.

  • Can I use wikipedia/commons images to create a logo for my program?

    - by bitmask
    I'm not perfectly clear on the implications of the GFDL for reusing pictures in this manner. Would adding a reference in the git's root folder's README suffice, or would that clutter every use of the logo, as you would have to attribute all original contributors on every single usage (like, e.g. presentations, flyers, websites, ...)? The software itself qualifies as FOSS, although it doesn't have a GNU* license.

  • I am trying to create an windows application watcher? [migrated]

    - by Broken_Code
    I recently started coding in c #(in may this year) and well I find it best to learn by working with code. this application http://www.c-sharpcorner.com/UploadFile/satisharveti/ActiveApplicationWatcher01252007024921AM/ActiveApplicationWatcher.aspx. I am trying to recreate it however mine will be saving the information into an sql database(new at this as well). I am having some coding problems though as it does not do what I expect it to do. THis is the main code I am using. private void GetTotalTimer() { DateTime now = DateTime.Now; IntPtr hwnd = APIFunc.getforegroundWindow(); Int32 pid = APIFunc.GetWindowProcessID(hwnd); Process p = Process.GetProcessById(pid); appName = p.ProcessName; const int nChars = 256; int handle = 0; StringBuilder Buff = new StringBuilder(nChars); handle = GetForegroundWindow(); appltitle = APIFunc.ActiveApplTitle().Trim().Replace("\0", ""); //if (GetWindowText(handle, Buff, nChars) > 0) //{ // string strbuff = Buff.ToString(); // StrWindow = strbuff; #region insert statement try { if (Conn.State == ConnectionState.Closed) { Conn.Open(); } if (Conn.State == ConnectionState.Open) { SqlCommand com = new SqlCommand("Select top 1 [Window Title] From TimerLogs ORDER BY [Time of Event] DESC", Conn); SqlDataReader reader = com.ExecuteReader(); startTime = DateTime.Now; string time = now.ToString(); if (!reader.HasRows) { reader.Close(); cmd = new SqlCommand("insert into [TimerLogs] values(@time,@appName,@appltitle,@Elapsed_Time,@userName)", Conn); cmd.Parameters.AddWithValue("@time", time); cmd.Parameters.AddWithValue("@appName", appName); cmd.Parameters.AddWithValue("@appltitle", appltitle); cmd.Parameters.AddWithValue("@Elapsed_Time", blank.ToString()); cmd.Parameters.AddWithValue("@userName", userName); cmd.ExecuteNonQuery(); Conn.Close(); } else if(reader.HasRows) { reader.Read(); if (appltitle != reader.ToString()) { reader.Close(); endTime = DateTime.Now; appduration = endTime.Subtract(startTime); cmd = new SqlCommand("insert into [TimerLogs] values (@time,@appName,@appltitle,@Elapsed_Time,@userName)", Conn); cmd.Parameters.AddWithValue("@time", time); cmd.Parameters.AddWithValue("@appName", appName); cmd.Parameters.AddWithValue("@appltitle", appltitle); cmd.Parameters.AddWithValue("@Elapsed_Time", appduration.ToString()); cmd.Parameters.AddWithValue("@userName", userName); cmd.ExecuteNonQuery(); reader.Close(); Conn.Close(); } } } } catch (Exception) { } //} #endregion ActivityTimer.Start(); Processing = "Working"; } Unfortunately this is the result. it is not saving the data as I expect it to. What am i doing wrong I had thought that with the sql reader it would first check for a value and only save if they do not match however it is saving whether there is a match or not.

  • Best way to create an exact twitter clone? From scratch vs CMS vs any other way [closed]

    - by Akash
    I tried many already built Twitter clone scripts but none was having user-end functionality exactly as twitter. I know enough PHP to code all the twitter's features myself. But is there a faster way than coding myself? I've never used a CMS but if I do then won't I have to search a plugin for every twitter feature, like support for multiple users, options for following-unfollowing users, retweeting (reposting someone else's post), tagging? And I'm afraid that there might be some licensing issues with CMS.

  • Remote Ajax Call in jQuery .click() function doesn't finish before going to next page.

    - by Clint
    I need to send click information on my website to a third party server using ajax (json). I am using jquery and I added the click event to certain links. In the click event I am making a json request to a remote server with the location of the click (heat map) and some other information. The problem is that the ajax function doesn't fire in time before the default link action happens. Setting async to false doesn't seem to work on remote ajax calls. I have tried preventDefault(), but then I don't know how to run the default action after the successful ajax call. Here is what I want to do: $('a').click(submit_click); function submit_click(e,fireAjax){ e.preventDefault(); cd_$.ajax({ url: jsonUrl, //remote server dataType: 'json', data: jsonData, async: false, success: function(reply){ //Run the default action here if I have to disable the default action }, }); } Any suggestions?

  • Create a screencast in a low end PC, but fast (maybe by sacrificing compression ?)

    - by josinalvo
    As the title suggests, I am asking a lot. We've been trying to generate some screencasts on my eeepc. recordmydesktop is doing the job decently, but only if allowed time to "compile" the video afterwards. If we ask it to do "on the fly", video and audio get out of sync. Now, we are creating many screencasts as practice (and like to watch them after, to criticize). Reducing quality is undesirable, because eventually a good practice run becomes the one we'll release. So we'd like a way to do screencasts "on the fly", with decent quality, on the low end machine. As nothing is ever free, we are willing to sacrifice: we don't care too much about compression: 20GB for a 15min video is acceptable

  • How does Against The Wall create an infinite wall?

    - by Zolani13
    There is a game called Against The Wall, developed by Michael P. Consoli. It's a fantastic game, as I've always been stumped at how the game creates an infinitely spanning wall. In the game, you can fall forever, and the wall will keep spanning. I can fall as long as I like, and still be able to climb back to where I was before. The game is developed in Unity. How can a game do this without crashing, or creating some kind of memory overload?

  • How to calculate Sin function quicker and more precisely?

    - by user1297181
    I want to calculate y(n)=32677Sin(45/1024•n), where y is an integer and n ranges from 0 to 2048. How can I make this process quicker and more precisely? Now I want to show you a reference answer: Since Sin(a+b)=Sin(a)Cos(b)+Cos(a)Sin(b) And Cos(a+b)=Cos(a)Cos(b)-Sin(a)Cos(b). So I can store Sin(45/1024•1) andCos(45/1024•1) ` only.Then use this formula: Sin(45/1024•2)=Sin(45/1024•1+45/1024•1), Cos(45/1024•2)=Cos(45/1024•1+45/1024•1), .... `Sin(45/1024•n)=Sin(45/1024•(n-1)+45/1024•1) `, `Cos(45/1024•n)=Cos(45/1024•(n-1)+45/1024•1) `, This way maybe quicker without storing large array.

  • Data Access Layer in ASP.Net: Where do I create the Connection?

    - by atticae
    If I want to create a 3-Layer ASP.Net application (Presentation Layer, Business Layer, Data Access Layer), where is the best place to create the Connection objects? So far I used a helper class in my Presentation Layer to create an IDbCommand from the ConnectionString in the web.config on each page and passed it on to the DAL classes/methods. Now I am not so sure, if this part shouldn't also be included in the DAL somehow, because it obviously is part of the Data Access. The DAL is in a separately compilated project, so I dont have access to the web.config and cannot access the connection string (right?). What is the best practice here?

  • I have a fucntion that create histogram of each Bitmap. How can i create another 3 histograms for R.G.B of each Bitmap?

    - by Daniel Lip
    This is the histogram function im using today and if im not worng it's creating an histogram by Gray color. What i want is another fucntion that will return me 3 histograms of each Bitmap: The first histogram will be of the Red color of the bitmap the second for the Green color and the last one for the Blue color. public static long[] GetHistogram(Bitmap b) { long[] myHistogram = new long[256]; BitmapData bmData = null; try { //Lock it fixed with 32bpp bmData = b.LockBits(new Rectangle(0, 0, b.Width, b.Height), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb); int scanline = bmData.Stride; System.IntPtr Scan0 = bmData.Scan0; unsafe { byte* p = (byte*)(void*)Scan0; int nWidth = b.Width; int nHeight = b.Height; for (int y = 0; y < nHeight; y++) { for (int x = 0; x < nWidth; x++) { long Temp = 0; Temp += p[0]; // p[0] - blue, p[1] - green , p[2]-red Temp += p[1]; Temp += p[2]; Temp = (int)Temp / 3; myHistogram[Temp]++; //we do not need to use any offset, we always can increment by pixelsize when //locking in 32bppArgb - mode p += 4; } } } b.UnlockBits(bmData); } catch { try { b.UnlockBits(bmData); } catch { } } return myHistogram; } How may i do it ?

  • If I create a link to a folder, how can I get from that linked folder to the "real" folder from within Nautilus?

    - by snowguy
    Say I have a folder several layers down in my documents folder. And I want easy access to it from my desktop. To do that I: Go to the parent folder in Nautilus. Right click on the folder's Icon and choose Make Link Cut / Paste the new "Link to ..." folder onto my desktop. Great. And mostly this works fine for me. But suppose I want to get to that folder's parent. I can of course get there using the original path--what Nautilus calls the "link path" which I can see in the properties of the folder. But that seems harder than it ought to be. How can I click on the folder and go to the link path directly?

  • how to use use case relations - uml

    - by joao alves
    Heys guys! Im have been study UML and im trying to to design the use case diagram of a problem. Lets supose my app consists in this: Two Requesites: - create teams - create players This is the deal: A user can create a team, and after create a team he can create players for that team(not required). But in this app there are multiple users, and a user can create a team and other user can create players. The only constraint is that to create players must exist alreay a team. I research and i end up a little confuse. If i get the concepts of relations on use case diagrams right, i think i should have the folowwing two use cases: [use case - create team] <-------extends---- [use case - create player] I need opinions,Is this the proper solution? or should i have two not related use cases? Thanks in advance, and im sorry my english.

  • How can I create multiple mini-sites with similar/duplicate content without hurting my search engine rank?

    - by ekpyrotic
    Essential background: I run a small company that lets members of the public post handwritten letters to their local politician (UK-based). Every week a number of early stage bills (called Early Day Motions) are submitted for debate in the House of Commons, and supporters of the motion will contact their local Members of Parliament, asking them to sign the motion. The crux: I want to target these EDMs with customised mini-sites, so when people search "EDM xxx", they find my customised mini-site, specifically targeting that EDM (i.e., "Send a handwritten letter to your MP asking them to sign EDM xxx"). At the moment, all these mini-sites (and my homepage) have duplicate content with only the relevant EDM name, number, and background image changed. (For example, http://mailmymp.com and http://mailmymp.com/edm/teaching-life-saving-skills-at-school-edm-550.php). The question: Firstly, will this hurt my potential search engine ranking? And, if so, what's the best way to target these political campaigns in an efficient manner without hurting my SEO prospects?

  • What's the simplest way to create a page with dynamic elements?

    - by ElendilTheTall
    I'm developing a site, part of which lists training courses with dates and prices. Every year the dates and prices change, which would mean loads of manual code editing to update the pages. What I'd like to do is have a database containing the relevant information, which the course pages then reference, so we can just update the database rather than the HTML. My experience lies in static design - so, what is a simple way to achieve this?

  • Javascript: Make a static code, dynamic - List of inputs

  • What TypeScript pattern can I use to enforce that a function gets a property?

    - by Matt York
    In JavaScript I can do this: function f() {} f.prop = "property"; I want this in TypeScript, but with type checking. What TypeScript pattern can I use to enforce that a function gets a property? Could I use an interface? interface functionWithProperty { (): any; prop: string; } This seems to be a valid interface in TypeScript, but how do I implement this interface such that the TypeScript compiler checks that prop is set? I saw this example: var f : functionWithProperty = (() => { var _f : any = function () { }; _f.prop = "blah"; return _f; }()); But this doesn't work because I can remove _f.prop = "blah"; and everything will still compile. I need to enforce that prop is set.
