  • Why do garbage collectors freeze execution?

    - by Martin
    I was thinking about garbage collection on the way home, and I began wondering, why does the garbage collector totally freeze execution of a program? Personally I would have designed it to block any threads which try to allocate a new object, but threads which were running would be left alone. I can't imagine any situation where this would be a problem compared to how a garbage collector currently works.

  • Which dll's are required to run osql.exe as a standalone?

    - by chama
    According to the accepted answer to this question, the osql.exe utility can be run as a standalone program on a computer without SQLServer, simply by copying the binary file to the new computer. My question is, however, which other files need to be copied along with osql.exe for it to work? Thanks so much!

  • What does int argc, char *argv[] mean?

    - by Greg Treleaven
    In many C++ IDE's and compilers, when it generates the main function for you, it looks like this: int main(int argc, char *argv[]) When I code C++ without an IDE, just with a command line compiler, I type: int main() without any parameters. What does this mean, and is it vital to my program?

  • Opengl Coordinate System

    - by praveen
    Say I am using an Identity Matrix for my modelViewTransformation Matrix on an Open GL ES2.0 program. The Co-ordinate system in this case is the canonical opengl co-ordinate system which extends from (-1,-1,-1) to (1,,1,1). My question is, is this coordinate system right-handed or left-handed? A broader question: Is there a document with OpenGL which can list all the mathematical conventions followed by the API?

  • ASP.net: Radio Button Not Maintaining Selection After Postback, Inside DIV/Thickbox

    - by jlrolin
    I have a set of radio buttons inside a hidden DIV. <div id="reports" style="display:none;"> <center> <br /> <table cellpadding="4" cellspacing="0"> <tr> <td class="label"> Report Type::&nbsp; </td> <td class="value"> <asp:RadioButton ID="rbReportTypeCust" runat="server" Text="By Customer" Enabled="True" Checked="True" GroupName="rbType" />&nbsp;<asp:RadioButton ID="rbReportTypeProg" runat="server" Text="By Program" Enabled="True" GroupName="rbType" /> </td> </tr> <tr> <td class="label"> Customer:&nbsp; </td> <td class="value"> <asp:DropDownList ID="ddlCustomer" runat="server" /> </td> </tr> <tr> <td class="label"> Program Group::&nbsp; </td> <td class="value"> <asp:DropDownList ID="ddlProgramGroups" runat="server" /> </td> </tr> </table> <br /> <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClientClick="doPostBack(this);" /> </center> </div> The DIV is displayed using Thickbox as a modal popup. The doPostback javascript function posts the button click back, and hits btnSubmit_Click where a report is then generated. If I see if a radio button is checked, it's always rbReportTypeCust.checked = True, never the rbReportTypeProg.checked = True even if I click it. Any suggestions?

  • Is there a method in Java that allows me to replace all HTML special characters into their encoded e

    - by Siracuse
    I have a textfile which my Java program is modifying and putting into an HTML file for display. However, this textfile contains lots of HTML unsafe characters such as "<" and the "" which would need to be encoded into & gt; (sans space) and & lt;. Is there some library method I can use to sanatize my text document to replace all these HTML special characters with their safe encoded equivelants?

  • Planning a database app

    - by ChrisC
    I am in the planning stages of a database app for personal use. I have a good bit of the database structure planned, but as I think about how I'm going to write the program, it made me wonder if I'm doing this in the right order. Which should I be planning first, the db structure or the classes?

  • gcc compiling invalid C code

    - by aks
    Some of my C programs are not working as expected. For example, pass by reference is not possible in C, but when I write a C program which uses that and compile it with gcc it works fine. Is gcc a C++ compiler? How do I make it behave like a C compiler?

  • Distinct rand() sequences yielding the same results in an expression

    - by suszterpatt
    Ok, this is a really weird one. I have an MPI program, where each process has to generate random numbers in a fixed range (the range is read from file). What happens is that even though I seed each process with a different value, and the numbers generated by rand() are different in each process, the expression to generate the random numbers still yields the same sequence between them. Here's all relevant code: // 'rank' will be unique for each process int rank; MPI_Comm_rank(MPI_COMM_WORLD, &rank); // seed the RNG with a different value for each process srand(time(NULL) + rank); // print some random numbers to see if we get a unique sequence in each process // 'log' is a uniquely named file, each process has its own log << rand() << " " << rand() << " " << rand() << std::endl; // do boring deterministic stuff while (true) { // waitTimeMin and waitTimeMax are integers, Max is always greater than Min waitSecs = waitTimeMin + rand() % (waitTimeMax - waitTimeMin); log << "waiting " << waitSecs << " seconds" << std::endl; sleep(waitSecs); // do more boring deterministic stuff } Here's the output of each process, with 3 processes generating numbers in the range [1,9]. process 1: 15190 28284 3149 waiting 6 seconds waiting 8 seconds waiting 9 seconds waiting 4 seconds process 2: 286 6264 3153 waiting 6 seconds waiting 8 seconds waiting 9 seconds waiting 4 seconds process 3: 18151 17013 3156 waiting 6 seconds waiting 8 seconds waiting 9 seconds waiting 4 seconds So while rand() clearly generates different numbers, the expression to calculate waitSecs still evaluates to the same sequence on all processes. What's even weirder: if I run the program with the same parameteres again, only the first 3 random numbers will change, the rest of the "random" sequence will be exactly the same in each run! Changing the range of numbers will obviously produce a different result from this one, but the same parameters always yield the same sequence, between processes and between executions: except for the first 3 numbers. Just what the hell is going on here?

  • New Bluetooth API question

    - by Ralphz
    I have written a small app that puts my bluetooth in discoverable mode for a long time (G1 - API 1.6). I use that along with small program on windows to lock/unlock the computer if the phone is close by. Recently i try to port this app to my nexus one but it seems like i have to pop up the message every 300s to enable device to go to discoverable mode. does anyone know how i can suppress that? I'm ok with saying ok for the first time but not every 300s :)

    I am writing a content provider for this application and in my content provider I am opening a database connection, running a query and returning the cursor of results to the calling program. If I close this database connection in the provider, the cursor has no results. If I leave it open, I get "leak found" errors in my DDMS log. What am I missing here? What's the clean, proper way to return a cursor of database results?
