  • Resizing a GLContext in Windows

    - by user146780
    I have a Win32 window and it has a gl context. I'm trying to figure out how to resize the context because even if I use glviewport it still stays the same size as when I created the context. Am I misunderstanding glviewport? i'm providing it the bottom left corner and the size I want but its still the original size that I made the context. Thanks

  • Initializing a char array through passed pointer segfaults

    - by Bitgarden
    Ie., why does the following work: char* char_array(size_t size){ return new char[size]; } int main(){ const char* foo = "foo"; size_t len = strlen(foo); char* bar=char_array(len); memset(bar, 0, len+1); } But the following segfaults: void char_array(char* out, size_t size){ out= new char[size]; } int main(){ const char* foo = "foo"; size_t len = strlen(foo); char* bar; char_array(bar, len); memset(bar, 0, len+1); }

  • C++ vector and segmentation faults

    - by Headspin
    I am working on a simple mathematical parser. Something that just reads number = 1 + 2; I have a vector containing these tokens. They store a type and string value of the character. I am trying to step through the vector to build an AST of these tokens, and I keep getting segmentation faults, even when I am under the impression my code should prevent this from happening. Here is the bit of code that builds the AST: struct ASTGen { const vector<Token> &Tokens; unsigned int size, pointer; ASTGen(const vector<Token> &t) : Tokens(t), pointer(0) { size = Tokens.size() - 1; } unsigned int next() { return pointer + 1; } Node* Statement() { if(next() <= size) { switch(Tokens[next()].type) { case EQUALS : Node* n = Assignment_Expr(); return n; } } advance(); } void advance() { if(next() <= size) ++pointer; } Node* Assignment_Expr() { Node* lnode = new Node(Tokens[pointer], NULL, NULL); advance(); Node* n = new Node(Tokens[pointer], lnode, Expression()); return n; } Node* Expression() { if(next() <= size) { advance(); if(Tokens[next()].type == SEMICOLON) { Node* n = new Node(Tokens[pointer], NULL, NULL); return n; } if(Tokens[next()].type == PLUS) { Node* lnode = new Node(Tokens[pointer], NULL, NULL); advance(); Node* n = new Node(Tokens[pointer], lnode, Expression()); return n; } } } }; ... ASTGen AST(Tokens); Node* Tree = AST.Statement(); cout << Tree->Right->Data.svalue << endl; I can access Tree->Data.svalue and get the = Node's token info, so I know that node is getting spawned, and I can also get Tree->Left->Data.svalue and get the variable to the left of the = I have re-written it many times trying out different methods for stepping through the vector, but I always get a segmentation fault when I try to access the = right node (which should be the + node) Any help would be greatly appreciated.

  • Java ArrayList remove dupes without sets

    - by Kieran
    I'm having problems removing duplicates from an ArrayList. It's for an assignment for college. Here's the code I have already: public int numberOfDiffWords() { ArrayList<String> list = new ArrayList<>(); for(int i=0; i<words.size()-1; i++) { for(int j=i+1; j<words.size(); j++) { if(words.get(i).equals(words.get(j))) { // do nothing } else { list.add(words.get(i)); } } } return list.size(); } The problem is in the numberOfDiffWords() method. The populate list method is working correctly, as my instructor has given me a sample string (containing 4465 words) to analyse - printing words.size() gives the correct result. I want to return the size of the new ArrayList with all duplicates removed. words is an ArrayList class attribute. UPDATE: I should have mentioned I'm only allowed to use dynamic indexed-based storage for this part of the assignment, which means no hash-based storage.

  • Converting image to Black & White image on iPhone SDK issues.

    - by KfirS
    Hello, I've used a familiar code to convert image to Black & White which I've founded on several forums. The code is: CGColorSpaceRef colorSapce = CGColorSpaceCreateDeviceGray(); CGContextRef context = CGBitmapContextCreate(nil, originalImage.size.width, originalImage.size.height, 8, originalImage.size.width, colorSapce, kCGImageAlphaNone); CGContextSetInterpolationQuality(context, kCGInterpolationHigh); CGContextSetShouldAntialias(context, NO); CGContextDrawImage(context, CGRectMake(0, 0, originalImage.size.width, originalImage.size.height), [originalImage CGImage]); CGImageRef bwImage = CGBitmapContextCreateImage(context); CGContextRelease(context); CGColorSpaceRelease(colorSapce); UIImage *resultImage = [UIImage imageWithCGImage:bwImage]; // This is result B/W image. CGImageRelease(bwImage); return resultImage; When I'm using this code with on Horizontal image it's work fine, but when I'm trying a to use this code on Vertical image, the result is disproportionate image and rotate 90 degree left. Can anyone know what could be the problem? Thanks, Kfir.

  • UIView animation problem

    - by FoJjen
    I try to make a UIImageView open like a hatch, and under the "hatchView" its anoter imageView but when I start the animation its like the view under gets over and cover the animation, When the animation gets over the imageView the its getting visibel. its works fine if a remove the imageView thats under. Here is the code for animation view. - (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *) event { if (!isHatchOpen) { if (hatchView.layer.anchorPoint.x != 0.0f) { hatchView.layer.anchorPoint = CGPointMake(0.0f, 0.5f); hatchView.center = CGPointMake(hatchView.center.x - hatchView.bounds.size.width/2.0f, hatchView.center.y); } UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:hatchView]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationBeginsFromCurrentState:YES]; float pct = location.x / 320.0f; float rad = acosf(pct); CATransform3D transform = CATransform3DMakeRotation(-rad+5, 0.0f, -1.0f, 0.0f); transform.m14 = (1.0 / -2000) * acosf(pct); hatchView.layer.transform = transform; [UIView commitAnimations]; isHatchOpen = YES; } else { if (hatchView.layer.anchorPoint.x != 0.0f) { hatchView.layer.anchorPoint = CGPointMake(0.0f, 0.5f); hatchView.center = CGPointMake(hatchView.center.x - hatchView.bounds.size.width/2.0f, hatchView.center.y); } [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationBeginsFromCurrentState:YES]; CATransform3D transform = CATransform3DMakeRotation(0, 0.0f, -1.0f, 0.0f); transform.m14 = 0; hatchView.layer.transform = transform; // Commit the changes [UIView commitAnimations]; isHatchOpen = NO; } } And here a add the Views hatchView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 1, frame.size.width-1, frame.size.height-2)]; [self addSubview:hatchView]; imageView = [[UIImageView alloc] initWithFrame:CGRectMake(1, 1, frame.size.width-2, frame.size.height-2)]; imageView.contentMode = UIViewContentModeScaleAspectFit; [self insertSubview:imageView belowSubview:hatchView];

  • CSS to position text based on Top of text?

    - by viatropos
    When I change the size of a font in CSS, how do I make it so no matter what size the font is (from 12px to 200px), that the "Cap Height" (pic) of the text will always 'visually' have 10px padding on top? Otherwise what I'm doing is every time I change the font size, I have to go back and reposition the top/margin-top etc.

  • What is required to create local business rich-snippets complete with sitelinks AND breadcrumbs?

    - by Felix
    I have a local business directory site. I would like to markup my business listing 'profile' level pages for display as enhanced listings/rich-snippets complete with business names, addresses and phone numbers. I would also like to display site-links and path-based breadcrumbs to help users navigate site directory hierarchy (which is deep). Is there a limit to the amount of breadcrumbs a site can leave? Is there a separate limit on the number of breadcrumbs which Google/Bing will display in the SERP? What kind of markup language(s) would be needed to best position my site to show site-links AND breadcrumbs? For example: Find a business Browse by Location State City Zip or Find a business Choose Service Browse by location State City Thanks all!

  • Get address using Geocoder in android

    - by user264953
    Hi, I tried to get the address of a particular location by giving static geocordinates. I was not able to fetch the address. Can someone please help. I just need to check whether this function works for me. Here is my snippet. Geocoder geocoder = new Geocoder(AddressSimulator.this, Locale.getDefault()); List<Address> addresses = geocoder.getFromLocation(1.352566007, 103.78921587, 1); System.out.println("Addresses size"+addresses.size()); Address size is obtained as zero. I tried with few other geocordinates also, but address size is always returned as 0. Experts, kindly help me resolve this. Looking forward for your valuable help/suggestions, Best Regards, Rony

  • C/C++ I18N mbstowcs question

    - by bogertron
    I am working on internationalizing the input for a C/C++ application. I have currently hit an issue with converting from a multi-byte string to wide character string. The code needs to be cross platform compatible, so I am using mbstowcs and wcstombs as much as possible. I am currently working on a WIN32 machine and I have set the locale to a non-english locale (Japanese). When I attempt to convert a multibyte character string, I seem to be having some conversion issues. Here is an example of the code: int main(int argc, char** argv) { wchar_t *wcsVal = NULL; char *mbsVal = NULL; /* Get the current code page, in my case 932, runs only on windows */ TCHAR szCodePage[10]; int cch= GetLocaleInfo( GetSystemDefaultLCID(), LOCALE_IDEFAULTANSICODEPAGE, szCodePage, sizeof(szCodePage)); /* verify locale is set */ if (setlocale(LC_CTYPE, "") == 0) { fprintf(stderr, "Failed to set locale\n"); return 1; } mbsVal = argv[1]; /* validate multibyte string and convert to wide character */ int size = mbstowcs(NULL, mbsVal, 0); if (size == -1) { printf("Invalid multibyte\n"); return 1; } wcsVal = (wchar_t*) malloc(sizeof(wchar_t) * (size + 1)); if (wcsVal == NULL) { printf("memory issue \n"); return 1; } mbstowcs(wcsVal, szVal, size + 1); wprintf(L"%ls \n", wcsVal); return 0; } At the end of execution, the wide character string does not contain the converted data. I believe that there is an issue with the code page settings, because when i use MultiByteToWideChar and have the current code page sent in EX: MultiByteToWideChar( CP_ACP, 0, mbsVal, -1, wcsVal, size + 1 ); in place of the mbstowcs calls, the conversion succeeds. My question is, how do I use the generic mbstowcs call instead of teh MuliByteToWideChar call?

  • Is there bug in the Matrix.RotateAt method for certain angles? .Net Winforms

    - by Jules
    Here's the code i'm using to rotate: Dim m As New System.Drawing.Drawing2D.Matrix Dim size = image.Size m.RotateAt(degreeAngle, New PointF(CSng(size.Width / 2), CSng(size.Height / 2))) Dim temp As New Bitmap(600, 600, Imaging.PixelFormat.Format32bppPArgb) Dim g As Graphics = Graphics.FromImage(temp) g.Transform = m g.DrawImage(image, 0, 0) (1) Disposals removed for brevity. (2) I test the code with a 200 x 200 rectangle. (3) Size 600,600 it just an arbitrary large value that I know will fit the right and bottom sides of the rotated image for testing purposes. (4) I know, with this code, the top and left edges will be clipped because I'm not transforming the orgin after the rotate. The problem only occurs at certain angles: (1) At 90, the right hand edge disappears completely. (2) At 180, the right and bottom edges are there, but very faded. (3) At 270, the bottom edge disappears completely. Is this a known bug? If I manually rotate the corners an draw the image by specifying an output rectangle, I don't get the same problem - though it is slightly slower than using RotateAt.

  • why does the array doesn't get initialized by global variable , even though it should not?

    why does the array a does not get initialized by global variable 'size'. include int size=5; int main() { int a[size]={1,2,3,4,5}; printf("%d",a[0]); return 0; } the compilation error is shown as "variable-sized object may not be initialized". according to me the array should get initialized by 'size'. i apologize if i am not clear but i feel i have expressed myself well enough. thank you!!!!!!!!!!!

  • How to listen to JComboBox's width changes?

PropertyChangeListener widthChangeListener = new PropertyChangeListener() { @Override public void propertyChange(PropertyChangeEvent evt) { //code } }; streamsComboBox.addPropertyChangeListener("width", widthChangeListener); projectsComboBox.addPropertyChangeListener("width", widthChangeListener); vobsComboBox.addPropertyChangeListener("width", widthChangeListener); Nothing works - the handler method is never fired. What should I do to handle JComboBox's size change? Where does the property name come from anyway?

  • Hiding iAds when loading?

    - by Jesper Mansa
    I'm trying to make an ios app with an iAd in the bottom but lifted a little bit. It actually woks ok but when the iAd is loading it shows an white area just below where the iAd should be. When its done loading the iAd jumps up in the right position. I think normaly the button is loaded outside the screen and nthen pop ups when done but because mine add is liftet a little I can see the loading area... Is there a way to make the iAd load in the sides instead and then popin from the side? Here is what I have so far: frame.origin.x = ( _screenWidth - frame.size.width ) / 2; if( calculateForBannerOnBottom ) frame.origin.y = _screenHeight - (frame.size.height/1.2); else frame.origin.y = -_adView.frame.size.height+(frame.size.height/2.4); Hoping 4 help and thanks in advance :-)

  • HashMap Memory Leak because of Dynamic Array

    - by Jake M
    I am attempting to create my own HashMap to understand how they work. I am using an array of Linked Lists to store the values(strings) in my hashmap. I am creating the array like this: Node** list; Instead of this: Node* list[nSize]; This is so the array can be any size at runtime. But I think I am getting a memory leak because of how I am doing this. I dont know where the error is but when I run the following simple code the .exe crashes. Why is my application crashing and how can I fix it? Note: I am aware that using a vector would be much better than an array but this is just for learning and I want to challenge myself to create the hashmap using a 'Dynamic' Array. PS: is that the correct term(Dynamic Array) for the kind of array I am using? struct Node { // to implement }; class HashMap { public: HashMap(int dynSize) { *list = new Node[dynSize]; size = dynSize; for (int i=0; i<size; i++) list[i] = NULL; cout << "END\n"; } ~HashMap() { for (int i=0; i<size; i++) delete list[i]; } private: Node** list; // I could use a vector here but I am experimenting with a pointer to an array(pointer), also its more elegant int size; }; int main() { // When I run this application it crashes. Where is my memory leak? HashMap h(5); system("PAUSE"); return 0; }
