  • Controling page number shown in printing dialog

    - by Matthias Wandel
    I'm trying to implement printing a range of pages in c# While printing, the .net framework throws up a message box that says "Page # of document". This starts at 1, and counts up to the number of pages printed. If I'm printing pages 10-11, I want that count to start at 10, not 1. Is there a way to set the starting value? The logical thing would be if it started at PrinterSettings.FromPage, but it ignores that value.

  • "Use of uninitialised value" despite of memset

    - by Framester
    Hi there, I allocate a 2d array and use memset to fill it with zeros. #include<stdio.h> #include<string.h> #include<stdlib.h> void main() { int m=10; int n =10; int **array_2d; array_2d = (int**) malloc(m*sizeof(int*)); if(array_2d==NULL) { printf("\n Could not malloc 2d array \n"); exit(1); } for(int i=0;i<m;i++) { ((array_2d)[i])=malloc(n*sizeof(int)); memset(((array_2d)[i]),0,sizeof(n*sizeof(int))); } for(int i=0; i<10;i++){ for(int j=0; j<10;j++){ printf("(%i,%i)=",i,j); fflush(stdout); printf("%i ", array_2d[i][j]); } printf("\n"); } } Afterwards I use valgrind [1] to check for memory errors. I get following error: Conditional jump or move depends on uninitialised value(s) for line 24 (printf("%i ", array_2d[i][j]);). I always thought memset is the function to initialize arrays. How can I get rid off this error? Thanks!

  • CoreGraphics taking a while to show on a large view - can i get it to repeat pixels?

    - by Andrew
    This is my coregraphics code: void drawTopPaperBackground(CGContextRef context, CGRect rect) { CGRect paper3 = CGRectMake(10, 14, 300, rect.size.height - 14); CGRect paper2 = CGRectMake(13, 12, 294, rect.size.height - 12); CGRect paper1 = CGRectMake(16, 10, 288, rect.size.height - 10); //Shadow CGContextSetShadowWithColor(context, CGSizeMake(0,0), 10, [[UIColor colorWithWhite:0 alpha:0.5]CGColor]); CGPathRef path = createRoundedRectForRect(paper3, 0); CGContextSetFillColorWithColor(context, [[UIColor blackColor] CGColor]); CGContextAddPath(context, path); CGContextFillPath(context); //Layers of paper //CGContextSaveGState(context); drawPaper(context, paper3); drawPaper(context, paper2); drawPaper(context, paper1); //CGContextRestoreGState(context); } void drawPaper(CGContextRef context, CGRect rect) { //Shadow CGContextSaveGState(context); CGContextSetShadowWithColor(context, CGSizeMake(0,0), 1, [[UIColor colorWithWhite:0 alpha:0.5]CGColor]); CGPathRef path = createRoundedRectForRect(rect, 0); CGContextSetFillColorWithColor(context, [[UIColor blackColor] CGColor]); CGContextAddPath(context, path); CGContextFillPath(context); //CGContextRestoreGState(context); //Gradient //CGContextSaveGState(context); CGColorRef startColor = [UIColor colorWithWhite:0.92 alpha:1.0].CGColor; CGColorRef endColor = [UIColor colorWithWhite:0.94 alpha:1.0].CGColor; CGRect firstHalf = CGRectMake(rect.origin.x, rect.origin.y, rect.size.width / 2, rect.size.height); CGRect secondHalf = CGRectMake(rect.origin.x + (rect.size.width / 2), rect.origin.y, rect.size.width / 2, rect.size.height); drawVerticalGradient(context, firstHalf, startColor, endColor); drawVerticalGradient(context, secondHalf, endColor, startColor); //CGContextRestoreGState(context); //CGContextSaveGState(context); CGRect redRect = rectForRectWithInset(rect, -1); CGMutablePathRef redPath = createRoundedRectForRect(redRect, 0); //CGContextSaveGState(context); CGContextSetStrokeColorWithColor(context, [[UIColor blackColor] CGColor]); CGContextAddPath(context, path); CGContextClip(context); CGContextAddPath(context, redPath); CGContextSetShadowWithColor(context, CGSizeMake(0, 0), 15.0, [[UIColor colorWithWhite:0 alpha:0.1] CGColor]); CGContextStrokePath(context); CGContextRestoreGState(context); } The view is a UIScrollView, which contains a textview. Every time the user types something and goes onto a new line, I call [self setNeedsDisplay]; and it redraws the code. But when the view starts to get long - around 1000 height, it has very noticeable lag. How can i make this code more efficient? Can i take a line of pixels and make it just repeat that, or stretch it, all the way down?

  • Why doesen't the number 2 work in this for-loop?

    - by Emil
    Hello. I have a function that runs trough each element in an array. It's hard to explain, so I'll just paste in the code here: NSLog(@"%@", arraySub); for (NSString *string in arrayFav){ int favoriteLoop = [string intValue] + favCount; NSLog(@"%d", favoriteLoop); id arrayFavObject = [array objectAtIndex:favoriteLoop]; [arrayFavObject retain]; [array removeObjectAtIndex:favoriteLoop]; [array insertObject:arrayFavObject atIndex:0]; [arrayFavObject release]; id arraySubFavObject = [arraySub objectAtIndex:favoriteLoop]; [arraySubFavObject retain]; [arraySub removeObjectAtIndex:favoriteLoop]; [arraySub insertObject:arraySubFavObject atIndex:0]; [arraySubFavObject release]; id arrayLengthFavObject = [arrayLength objectAtIndex:favoriteLoop]; [arrayLengthFavObject retain]; [arrayLength removeObjectAtIndex:favoriteLoop]; [arrayLength insertObject:arrayLengthFavObject atIndex:0]; [arrayLengthFavObject release]; } NSLog(@"%@", arraySub); The array arrayFav contains these strings: "3", "8", "2", "10", "40". Array array contains 92 strings with a name. Array arraySub contains numbers 0 to 91, representing a filename with a title from the array array. Array arrayLength contains 92 strings representing the size of each file from array arraySub. Now, the first NSLog shows, as expected, the numbers 0 to 91. The NSLog-s in the loop shows the numbers 3, 8, 2, 10, 40, also as expected. But here's the odd part: the last NSLog shows these numbers: 40, 10, 0, 8, 3, 1, 2, 4, 5, 6, 7, 9, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91 that is 40, 10, 0, 8, 3, and so on. It was not supposed to be a zero in there, it was supposed to be a 2.. Do you have any idea at why this is happening or a way to fix it? Thank you.

  • CSS :nth-child Equation

    - by Meander365
    I have an unordered list and each li makes up one item in a two column layout: col1 col2 1 2 3 4 5 6 7 8 9 10 11 12 I need to have an alternating background colour for each item BUT NOT so each item in one column is the same. So : 1,4,5,8,9,11 will have one colour; and 2,3,6,7,10,12 will have another colour. Can this be achieved with one :nth-child rule? Thanks!

  • Silverlight MouseMove: find missing points during a movement

    - by Jalfp
    In an application in Silverlight I'm working on, I need to track the moves of the mouse. My problem is that using the MouseMove event, I don't have a continuous set of points if the user moves the mouse fast enough (if I add each point in a list I can have (10,10) en then (20,20)...) I'd like to have ALL points where the mouse has been during the move. Do you have any idea ?

  • Using custom .jar's in your java project

    Hi guys, I'm importing from two jar's twitter4j-2.0.10.jar and mysql-connector-java-5.1.10-bin.jar, I'm running the code on a server but it's not letting me. I get a.. Streamer.java:9: package twitter4j does not exist import twitter4j.StatusDeletionNotice; ^ error when compiling. I know this has something to do with getting java to recognise my custom jar's but I don't know how to get java to "see" them. Any ideas?

    Hi, Why don't clear all Array list data?

  • How do I get results from a Linq query in the order of IDs that I provide?

    - by Keltex
    I'm looking to get query results back from Linq in the order that I pass IDs to the query. So it would look something like this: var IDs = new int [] { 5, 20, 10 } var items = from mytable in db.MyTable where IDs.Contains(mytable.mytableID) orderby // not sure what to do here select mytable; I'm hoping to get items in the order of IDs (5, 20, 10). (Note this is similar to this question, but I would like to do it in Linq instead of SQL)

  • Resize jqGrid based on number of rows?

    - by Rosdi
    I want my jqGrid to shrink and expand based on the number of rows it has. Let say it currently has 10 rows, the height of the jqGrid will shrink to 10 rows (so that no gaping empty rows is exposed). If however there are too many rows, the height of the grid will expand to a maximum 'height' value and a scroll bar will appear.

  • JNI String Corruption

    - by Chris Dennett
    Hi everyone, I'm getting weird string corruption across JNI calls which is causing problems on the the Java side. Every so often, I'll get a corrupted string in the passed array, which sometimes has existing parts of the original non-corrupted string. The C++ code is supposed to set the first index of the array to the address, it's a nasty hack to get around method call limitations. Additionally, the application is multi-threaded. remoteaddress[0]: 10.1.1.2:49153 remoteaddress[0]: 10.1.4.2:49153 remoteaddress[0]: 10.1.6.2:49153 remoteaddress[0]: 10.1.2.2:49153 remoteaddress[0]: 10.1.9.2:49153 remoteaddress[0]: {garbage here} java.lang.NullPointerException at kokuks.KKSAddress.<init>(KKSAddress.java:139) at kokuks.KKSAddress.createAddress(KKSAddress.java:48) at kokuks.KKSSocket._recvFrom(KKSSocket.java:963) at kokuks.scheduler.RecvOperation$1.execute(RecvOperation.java:144) at kokuks.scheduler.RecvOperation$1.execute(RecvOperation.java:1) at kokuks.KKSEvent.run(KKSEvent.java:58) at kokuks.KokuKS.handleJNIEventExpiry(KokuKS.java:872) at kokuks.KokuKS.handleJNIEventExpiry_fjni(KokuKS.java:880) at kokuks.KokuKS.runSimulator_jni(Native Method) at kokuks.KokuKS$1.run(KokuKS.java:773) at java.lang.Thread.run(Thread.java:717) remoteaddress[0]: 10.1.7.2:49153 The null pointer exception comes from trying to use the corrupt string. In C++, the address prints to standard out normally, but doing this reduces the rate of errors, from what I can see. The C++ code (if it helps): /* * Class: kokuks_KKSSocket * Method: recvFrom_jni * Signature: (Ljava/lang/String;[Ljava/lang/String;Ljava/nio/ByteBuffer;IIJ)I */ JNIEXPORT jint JNICALL Java_kokuks_KKSSocket_recvFrom_1jni (JNIEnv *env, jobject obj, jstring sockpath, jobjectArray addrarr, jobject buf, jint position, jint limit, jlong flags) { if (addrarr && env->GetArrayLength(addrarr) > 0) { env->SetObjectArrayElement(addrarr, 0, NULL); } jboolean iscopy; const char* cstr = env->GetStringUTFChars(sockpath, &iscopy); std::string spath = std::string(cstr); env->ReleaseStringUTFChars(sockpath, cstr); // release me! if (KKS_DEBUG) { std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << std::endl; } ns3::Ptr<ns3::Socket> socket = ns3::Names::Find<ns3::Socket>(spath); if (!socket) { std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " socket not found for path!!" << std::endl; return -1; // not found } if (!addrarr) { std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " array to set sender is null" << std::endl; return -1; } jsize arrsize = env->GetArrayLength(addrarr); if (arrsize < 1) { std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " array too small to set sender!" << std::endl; return -1; } uint8_t* bufaddr = (uint8_t*)env->GetDirectBufferAddress(buf); long bufcap = env->GetDirectBufferCapacity(buf); uint8_t* realbufaddr = bufaddr + position; uint32_t remaining = limit - position; if (KKS_DEBUG) { std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " bufaddr: " << bufaddr << ", cap: " << bufcap << std::endl; } ns3::Address aaddr; uint32_t mflags = flags; int ret = socket->RecvFrom(realbufaddr, remaining, mflags, aaddr); if (ret > 0) { if (KKS_DEBUG) std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " addr: " << aaddr << std::endl; ns3::InetSocketAddress insa = ns3::InetSocketAddress::ConvertFrom(aaddr); std::stringstream ss; insa.GetIpv4().Print(ss); ss << ":" << insa.GetPort() << std::ends; if (KKS_DEBUG) std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " addr: " << ss.str() << std::endl; jsize index = 0; const char *cstr = ss.str().c_str(); jstring jaddr = env->NewStringUTF(cstr); if (jaddr == NULL) std::cout << "[kks-c~" << spath << "] " << __PRETTY_FUNCTION__ << " jaddr is null!!" << std::endl; //jaddr = (jstring)env->NewGlobalRef(jaddr); env->SetObjectArrayElement(addrarr, index, jaddr); //if (env->ExceptionOccurred()) { // env->ExceptionDescribe(); //} } jint jret = ret; return jret; } The Java code (if it helps): /** * Pass an array of size 1 into remote address, and this will be set with * the sender of the packet (hax).
