  • Help with SQL query in C#

    - by DanSogaard
    I'm trying to rename the columns. The syntax should be the column name between double quotes incase of two words, like this: SELECT p_Name "Product Name" from items So I'm trying to do it in C# code like this: string sqlqry1 = "SELECT p_Name \"Prodcut Name\" from items"; But I get an error: Syntax error (missing operator) in query expression 'p_Name "Prodcut Name"'. It seems am having somthing wrong with the quotes, but I can't figure out.

    Hi, Can someone explain to me the usage of Integer, Boolean etc in place of their primitive types in JAVA? I can't seem to grasp the advantages their are providing. They seem to create unnecessary problems of handling null values. Thanks!

  • Haskell: Gluing a char and a list together?

    - by Vincent
    So I have this code here: toWords :: String - [a] toWords "" = [] toWords (nr1 : rest) | nr1 == ' ' = toWords rest | otherwise = nr1 : toWords rest The "toWords" function should simply remove all spaces and return a list with all the words. But I keep getting this error: test.hs:5:18: Couldn't match expected type a' against inferred typeChar' `a' is a rigid type variable bound by the type signature for `toWords' at test.hs:1:22 In the first argument of `(:)', namely `nr1' In the expression: nr1 : toWords rest In the definition of `toWords': toWords (nr1 : rest) | nr1 == ' ' = toWords rest | otherwise = nr1 : toWords rest Failed, modules loaded: none.

  • PHP something faster than explode to get filename from URL

    - by FFish
    My URL's can be absolute or relative: $rel = "date/album/001.jpg"; $abs = "http://www.site.com/date/album/image.jpg"; function getFilename($url) { $imgName = explode("/", $url); $imgName = $imgName[count($imgName) - 1]; echo $imgName; } There must be a faster way to do this right? Maybe a reg expression? But that's Chinese to me..

  • Checking an empty Core Data relationship (SQLite)

    - by rwat
    I have a to-many relationship in my data model, and I'd like to get all the objects that have no corresponding objects in the relationship. For example: Customer - Purchases I want to get all Customers that have 0 Purchases. I've read somewhere that I could use "Purchases[SIZE] = 0", but this gives me an unsupported function expression error, which I think means it doesn't work with a SQLite backing store (which I don't want to switch from, due to some performance constraints). Any ideas?

  • Regex for Eclipse/Flash Builder File Search for comments?

    - by Brian Bishop
    In Eclipse (and Flash/Flex Builder) you get the option with Ctrl+Shift+F to do a file search and look for a regular expression. Would be a real handy thing to know. I want to find the word negate if it appears in a Flex/java comment like the following: // It was negated because or /* The negate option was.... */ or /** * We have to negate the value */ Any ideas? Will test them out at http://www.regexplanet.com/simple/index.html

  • Collision Detection for arbitrarily sized, positioned and rotated rectangles in XNA

    - by Stefan
    I'm working with xna in C# and in my game I will have a variety of space ships flying all over the place. They will each have an arbitrary rotation, size and position in space and I need a method to determine when they collide. Ideally the method would take two Rectangles, two doubles and two Vector2s for size, rotation and position respectively and return a boolean that indicates whether they have intersected or not.

  • Send a variable on the heap to another thread

    - by user1201889
    I have a strange problem in C++. An address of a Boolean gets "destroyed" but it doesn't get touched. I know that there are beater way's to accomplish what I try to do, but I want to know what I do wrong. I have a main class; this main class contains a vector of another class. There is a strange problem when a new instance gets created of this object. This is how my code works: There will start a thread when the constructor gets called of the “2nd”object. This thread gets as Parameter a struct. This is the struct: struct KeyPressData { vector<bool> *AutoPressStatus; vector<int> *AutoPressTime; bool * Destroy; bool * Ready; }; The struct gets filled in the constructor: MultiBoxClient::MultiBoxClient() { //init data DestroyThread = new bool; ReadyThread = new bool; AutoThreadData = new KeyPressData; //Reseting data *DestroyThread = false; *ReadyThread = false; //KeyPressData configurating AutoThreadData->AutoPressStatus = &AutoPressStatus; AutoThreadData->AutoPressTime = &AutoPressTime; AutoThreadData->Destroy = DestroyThread; AutoThreadData->Ready = ReadyThread; //Start the keypress thread CreateThread(NULL,NULL,(LPTHREAD_START_ROUTINE)AutoKeyThread,AutoThreadData,NULL,NULL); } As long as the constructor is running will the program run fine. But when the constructor closes the address of the “AutoThreadData-Destroy” will get corrupted. The program will crash when I call the value of the pointer. void WINAPI AutoKeyThread(void * ThreadData) { KeyPressData * AutoThreadData = (KeyPressData*)ThreadData; while(true) { if(*AutoThreadData->Destroy == true) //CRASH { *AutoThreadData->Ready = true; return; } Sleep(100); } } What did I test: I logged the address of the AutoThreadData and the AutoThreadData-Destroy when the constrcutor is running and clossed; the AutoThreadData address is equal to AutoThreadData when the constructor is closed. So there is no problem here. The address of AutoThreadData-Destroy gets destroyed when the constructor is closed. But how can this happen? The Boolean is on the heap and the KeyPressData struct (AutoThreadData) is on the heap. Destroy before: 00A85328 Destroy after: FEEEFEEE Can someone maby explain why this crash? I know that I can send a pointer to my class to the thread. But I want to know what goes wrong here. That way I can learn from my mistakes. Could someone help me with this problem? Thanks!

    - by John Apple Sim
    I have a SurfaceView and I want the Bitmap Logo inside it in the canvas to be movable What I'm doing wrong ? static float x, y; Bitmap logo; SurfaceView ss = (SurfaceView) findViewById(R.id.svSS); logo = BitmapFactory.decodeResource(getResources(), R.drawable.logo); x = 40; y = 415; ss.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent me) { try { Thread.sleep(50); } catch (InterruptedException e) { e.printStackTrace(); } switch(me.getAction()) { case MotionEvent.ACTION_DOWN: x = me.getX(); y = me.getY(); break; case MotionEvent.ACTION_UP: x = me.getX(); y = me.getY(); break; case MotionEvent.ACTION_MOVE: x = me.getX(); y = me.getY(); break; } return true; } }); public class OurView extends SurfaceView implements Runnable{ Thread t = null; SurfaceHolder holder; boolean isItOK = false; public OurView(Context context) { super(context); holder = getHolder(); } public void run (){ while (isItOK == true){ //canvas DRAWING if (!holder.getSurface().isValid()){ continue; } Canvas c = holder.lockCanvas(); c.drawARGB(255, 200, 100, 100); c.drawBitmap(logo, x,y,null); holder.unlockCanvasAndPost(c); } } public void pause(){ isItOK = false; while(true){ try { t.join(); } catch (InterruptedException e) { e.printStackTrace(); } break; } t = null; } public void resume(){ isItOK = true; t = new Thread(this); t.start(); } } Now the surface view is just black .. nothing happens also its not colored 200, 100, 100

  • Converting html entities into their values in python

    - by tipu
    I use this regex on some input, [^a-zA-Z0-9@#] However this ends up removing lots of html special characters within the input, such as 227;, #1606;, #1588; (i had to remove the & prefix so that it wouldn't show up as the actual value..) is there a way that I can convert them to their values so that it will satisfy the regexp expression? I also have no idea why the text decided to be so big.
