• PostgreSQL - CREATE INDEX

  - by mocopera

  Hi! I'm working with PostgreSQL to create some data types written in C. For example, I have: typedef struct Point3D { char id[50]; double x; double y; double z; } Point3D; The input and output functions are working properly. But the problem is the following: Every id of Point3D must be unique (and can be NULL), so I have decided to create an unique index on this field id, but is that possible? I'm thinking in something like this: create unique index test_point3d_idx on test_point3d (( getID(columname) )); where getID returns the field ID of columname. But I need to implement getID and I am really blocked. Any advice?

• SDL with OpenGL (freeglut) crashes on call to glutBitmapCharacter

  - by stett

  I have a program using OpenGL through freeglut under SDL. The SDL/OpenGL initialization is as follows: // Initialize SDL SDL_Init(SDL_INIT_VIDEO); // Create the SDL window SDL_SetVideoMode(SCREEN_W, SCREEN_H, SCREEN_DEPTH, SDL_OPENGL); // Initialize OpenGL glClearColor(BG_COLOR_R, BG_COLOR_G, BG_COLOR_B, 1.f); glViewport(0, 0, SCREEN_W, SCREEN_H); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0.0f, SCREEN_W, SCREEN_H, 0.0f, -1.0f, 1.0f); glEnable(GL_TEXTURE_2D); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); I've been using glBegin() ... glEnd() blocks without any trouble to draw primitives. However, in this program when I call any glutBitmapX function, the program simply exits without an error status. The code I'm using to draw text is: glColor3f(1.f, 1.f, 1.f); glRasterPos2f(x, y); glutStrokeString(GLUT_BITMAP_8_BY_13, (const unsigned char*)"test string"); In previous similar programs I've used glutBitmapCharacter and glutStrokeString to draw text and it's seemed to work. The only difference being that I'm using freeglut with SDL now instead of just GLUT as I did in previous programs. Is there some fundamental problem with my setup that I'm not seeing, or is there a better way of drawing text?

• File.mkdir is not working and I can't understand why

  - by gotch4

  Hello, I've this brief snippet: String target = baseFolder.toString() + entryName; target = target.substring(0, target.length() - 1); File targetdir = new File(target); if (!targetdir.mkdirs()) { throw new Exception("Errore nell'estrazione del file zip"); } doesn't mattere if I leave the last char (that is usually a slash). It's done this way to work on both unix and windows. The path is actually obtained from the URI of the base folder. As you can see from baseFolder.toString() (baseFolder is of type URI and is correct). The base folder actually exists. I can't debug this because all I get is true or false from mkdir, no other explanations.The weird thing is that baseFolder is created as well with mkdir and in that case it works. Now I'm under windows. the value of target just before the creation of targetdir is "file:/C:/Users/dario/jCommesse/jCommesseDB" if I cut and paste it (without the last entry) in windows explore it works...

• strerror_r returns trash when I manually set errno during testing

  - by Robert S. Barnes

  During testing I have a mock object which sets errno = ETIMEDOUT; The object I'm testing sees the error and calls strerror_r to get back an error string: if (ret) { if (ret == EAI_SYSTEM) { char err[128]; strerror_r(errno, err, 128); err_string.assign(err); } else { err_string.assign(gai_strerror(ret)); } return ret; } I don't understand why strerror_r is returning trash. I even tried calling strerror_r(ETIMEDOUT, err, 128) directly and still got trash. I must be missing something. It seems I'm getting the gnu version of the function not the posix one, but that shouldn't make any difference in this case.

• Why is setting HTML5's CanvasPixelArray values is ridiculously slow and how can I do it faster?

  - by Nixuz

  I am trying to do some dynamic visual effects using the HTML 5 canvas' pixel manipulation, but I am running into a problem where setting pixels in the CanvasPixelArray is ridiculously slow. For example if I have code like: imageData = ctx.getImageData(0, 0, 500, 500); for (var i = 0; i < imageData.length; i += 4){ imageData.data[index] = buffer[i]; imageData.data[index + 1] = buffer[i]; imageData.data[index + 2] = buffer[i]; } ctx.putImageData(imageData, 0, 0); Profiling with Chrome reveals, it runs 44% slower than the following code where CanvasPixelArray is not used. tempArray = new Array(500 * 500 * 4); imageData = ctx.getImageData(0, 0, 500, 500); for (var i = 0; i < imageData.length; i += 4){ tempArray[index] = buffer[i]; tempArray[index + 1] = buffer[i]; tempArray[index + 2] = buffer[i]; } ctx.putImageData(imageData, 0, 0); My guess is that the reason for this slowdown is due to the conversion between the Javascript doubles and the internal unsigned 8bit integers, used by the CanvasPixelArray. Is this guess correct? Is there anyway to reduce the time spent setting values in the CanvasPixelArray?

• Inserting non-pod struct into a GHashTable

  - by RikSaunderson

  Hi there, I'm trying to build a GHashTable of instances of a struct containing ints, a time_t and a few char*'s. My question is, how do you insert an instance of a struct into a GHashTable? there are plenty of examples of how to insert a string or an int (using g_str_hash and g_int_hash respectively), but I'm guessing thatI want to use the g_direct_hash, and I can't seem to find any examples of that. Ideally, my code would look like this: GHashtable table; table = g_hash_table_new(g_direct_hash, g_direct_equal); struct mystruct; mystruct.a = 1; mystruct.b = "hello"; mystruct.c = 5; mystruct.d = "test"; g_hash_table_insert(table,mystruct.a,mystruct); Clearly, this is incorrect as it does not compile. Can anyone provide an example that does do what I want? Thanks, Rik

• Can't append space at end of UITextView

  - by Sam V

  I have a UITextView in which I want the initial value to be "@username " (notice the space after the username). This way the user can start typing right away without having to tap space. So I do: textView.text = [NSString stringWithFormat:@"@%@ ", username]; But it seems like it's impossible to have the UITextView text property ending with a space (it always gets stripped out). Am I correct? Is there any workaround for this? I tried using the \s char and no success.

• unistd.h related problem when compiling bison & flex program under vc++

  - by Eric

  I'm using bison & flex (downloaded via cygwin) with vc++. When I compile the program I got an error: ...: fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory The corresponding code in the flex-generated file is: #ifndef YY_NO_UNISTD_H /* Special case for "unistd.h", since it is non-ANSI. We include it way * down here because we want the user's section 1 to have been scanned first. * The user has a chance to override it with an option. */ /* %if-c-only */ #include <unistd.h> /* %endif */ /* %if-c++-only */ /* %endif */ #endif If I define YY_NO_UNISTD_H in the flex file(.l) this error will disappear, but I get several other errors: ...: error C2447: '{' : missing function header (old-style formal list?) ...: warning C4018: '<' : signed/unsigned mismatch ...: error C3861: 'isatty': identifier not found How can I fix this problem? All these errors occur in the flex-generated scanner. I know it's because unistd.h doesn't exist in windows. Do I have to write my own unistd.h? If so how to write it in order to eliminate those errors?

• algorithm to find overlaps

  - by Gary

  Hey, Basically I've got some structs of type Ship which are going to go on a board which can have a variable width and height. The information about the ships is read in from a file, and I just need to know the best way to make sure that none of the ships overlap. Here is the structure of Ship: int x // x position of first part of ship int y // y position of first part of ship char dir // direction of the ship, either 'N','S','E' or 'W' int length // length of the ship Also, what would be a good way to handle the directions. Something cleaner than using a switch statement and using a different condition for each direction. Any help would be greatly appreciated!

• Printf is not printing anything to output? C++ SDL

  - by Qasim

  I am trying to use "printf" in my Visual C++ project however it is not working. Using Lazy Foo's tutorial, I set up SDL in my project, but when I play it, printf doesnt do anything. #include "SDL.h" #include <stdio.h> int main( int argc, char* args[] ) { printf("Testing"); return 0; } The output looks like this: The program '[4664] SDL Testing.exe: Native' has exited with code 0 (0x0). And that's about it. What could be wrong?

• Delphi Unicode String Type Stored Directly at its Address (or "Unicode ShortString")

  - by Andreas Rejbrand

  I want a string type that is Unicode and that stores the string directly at the adress of the variable, as is the case of the (Ansi-only) ShortString type. I mean, if I declare a S: ShortString and let S := 'My String', then, at @S, I will find the length of the string (as one byte, so the string cannot contain more than 255 characters) followed by the ANSI-encoded string itself. What I would like is a Unicode variant of this. That is, I want a string type such that, at @S, I will find a unsigned 32-bit integer (or a single byte would be enough, actually) containing the length of the string in bytes (or in characters, which is half the number of bytes) followed by the Unicode representation of the string. I have tried WideString, UnicodeString, and RawByteString, but they all appear only to store an adress at @S, and the actual string somewhere else (I guess this has do do with reference counting and such). Update: The most important reason for this is probably that it would be very problematic if sizeof(string) were variable. I suspect that there is no built-in type to use, and that I have to come up with my own way of storing text the way I want (which actually is fun). Am I right? Update I will, among other things, need to use these strings in packed records. I also need manually to read/write these strings to files/the heap. I could live with fixed-size strings, such as <= 128 characters, and I could redesign the problem so it will work with null-terminated strings. But PChar will not work, for sizeof(PChar) = 1 - it's merely an address. The approach I eventually settled for was to use a static array of bytes. I will post my implementation as a solution later today.

• C++ Microsoft SAPI: How to set Windows text-to-speech output to a memory buffer?

  - by Vladimir

  Hi all, I have been trying to figure out how to "speak" a text into a memory buffer using Windows SAPI 5.1 but so far no success, even though it seems it should be quite simple. There is an example of streaming the synthesized speech into a .wav file, but no examples of how to stream it to a memory buffer. In the end I need to have the synthesized speech in a char* array in 16 kHz 16-bit little-endian PCM format. Currently I create a temp .wav file, redirect speech output there, then read it, but it seems to be a rather stupid solution. Anyone knows how to do that? Thanks!

• Inserting nil Values into Sqlite Database?

  - by Chris

  I am working on an iPhone App where I am pulling data from an XML file and inserting it into a sqlite database located in the App. I am able to successfully do this process, but it appears that if I try to sqlite3_bind_text with a NSString that has a value of "nil", the App quickly dies. This is an example of code that fails: (modified for this example) // idvar = 1 // valuevar = nil const char *sqlStatement = "insert into mytable (id, value) VALUES(?, ?)"; sqlite3_stmt *compiledStatement = nil; sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL); sqlite3_bind_int(compiledStatement, 1, [idvar intValue]);; sqlite3_bind_text(compiledStatement, 2, [valuevar UTF8String], -1, SQLITE_TRANSIENT);

• code optimization; switch versus if's

  Hello, I have a question about whether to use 'case' or 'ifs' in a function that gets called quite alot. Here's the following as it is now, in 'ifs'; the code is self-explanatory: int identifyMsg(char* textbuff) { if (!strcmp(textbuff,"text")) { return 1; } if (!strcmp(textbuff,"name")) { return 2; } if (!strcmp(textbuff,"list")) { return 3; } if (!strcmp(textbuff,"remv")) { return 4; } if (!strcmp(textbuff,"ipad")) { return 5; } if (!strcmp(textbuff,"iprm")) { return 6; } return 0; } My question is: Would a switch perform better? I know if using ifs, I can place the most likely options at the top.

• Pushing a variable onto a vector, value at that point in vector changes when the variable does.

  - by David Andrews

  I have a programming problem =) std::vector<char*> Names; if(MyPacket.ID == 3) {Names.push_back(MyPacket.Buffer);} I push the recieved buffer onto a vector like so, but when the buffer changes so does the value of the variable at that point in the vector. So say I sent and pushed a buffer containing 'Simon' onto the vector that would be fine so at point [0] on the vector would be the word Simon. but then when I recieve a new buffer it overwrites position [0] even though the packets ID is different, a breakpoint within the if statement is not reached with this new buffer. I really hope i'm explaining this well enough, I tried asking a friends advice and he pointed me towards this site. Any help appreciated David Andrews

• This regx does not work only in Chrome

  Hi i just put up a validation function in jScript to validate filename in fileupload control[input type file]. The function seems to work fine in FF and sometimes in ie but never in Chrome. Basically the function tests if File name is atleast 1 char upto 25 characters long.Contains only valid characters,numbers [no spaces] and are of file types in the list. Could you throw some light on this function validate(Uploadelem) { var objRgx = new RegExp(/^[\w]{1,25}\.*\.(jpg|gif|png|jpeg|doc|docx|pdf|txt|rtf)$/); objRgx.ignoreCase = true; if (objRgx.test(Uploadelem.value)) { document.getElementById('moreUploadsLink').style.display = 'block'; } else { document.getElementById('moreUploadsLink').style.display = 'none'; } }
