Hi, I am looking for documentation on how to commonly do the technical part of publishing the source of first open source projects, in particular with library-intensive stuff in C/C++, Java, Python. To give an example, if I built a C++ project with an IDE like Netbeans and various libraries like Xerces-C and Boost, I would like to find...
I have a win 32 application written in c++ which sets the low level keyboard hook. now i want to sendInput to any app like word / notepad. how do i do this? i have already done enough of using findwindow / sendmessage. for all these, i need to know edit controls. finding the edit control is very difficult. since SendInput works for any...
I have to port a C++ STL application to Python. I am a Python newbie, but have been programming for over a decade. I have a great deal of experience with the STL, and find that it keeps me hooked to using C++. I have been searching for the following items on Google these past several days: Python STL (in hope of leveraging my years of ...
I have installed visual studio 2008 and i want to create some simple applications using C language. I do this by creating c++ console applications but i want the compiler to work for C not C++. Any way to accomplish this or i need another compiler if i want to deal with C? ...

Hello, How can I specify some unique flags for DLL only builds. By default libtool adds -DDLL_EXPORT which is fine for most projects that follow GNU conventions, but if I work, for example, with Boost I may need to specify for my library flags: -DDLL_EXPORT -DBOOST_ALL_DYN_LINK for DLL only builds, also sometimes I want conditional buil...
Hi, I have got a structure and in it a pointer to a 2D array. But when I try to assign an actual 2D array to that pointer I do not succeed - compiler says that my pointer is a pointer to a 1D array. Here's my code: typedef GLfloat Vertex2f[2]; typedef GLfloat TextureCoordinate[2]; typedef struct { GLuint texture_name; // OpenGL...
Is there a way of supplying enum values as method-args in pococapsule without resorting to factory-methods? Let say I have a class that take an enum value in its constructor class A { A(myEnum val); } Using Pococapsule xml configuration: I would like to express something like this: <bean id="A" class="A"> <method-arg type="M...
When I include winsock2.h, I get about 60 redefinition errors. I hunted around a bit a found some advice to include winsock2.h b4 including windows.h. I did that and that cleared up the errors. My problem and question concerns exactly how I should go about doing this. I did not explicitly include windows.h, it was done for me in stda...
How would you fix the following bad code that passes too many parameters around? void helper1(int p1, int p3, int p5, int p7, int p9, int p10) { // ... } void helper2(int p1, int p2, int p3, int p5, int p6, int p7, int p9, int p10) { // ... } void foo(int p1, int p2, int p3, int p4, int p5, int p6, int p7, int p8, int p9...
What is the Java equivalent of following C++ code? float f=12.5f; int& i = reinterpret_cast<int&>(f); ...
I'm using a typedef to define the type of a container in my program so that I can easily switch between using normal STL containers and STXXL containers, along the lines of: typedef stxxl:vector<Data> MyContainer; or typedef std:vector<Data> MyContainer; One difficulty is that STXXL provides a special version of std::for_each, stxx...
Hi everyone, Does anyone know how to calculate the error of quantizing from 16bit to 8bit? I have looked at the Wikipedia article about Quantization, but it doesn't explain this. Can anyone explain how it is done? Lots of love, Louise Update: My function looks like this. unsigned char quantize(double d, double max) { return (unsi...
This is a part of an open source project called JNotify. I am trying to fix the Win32 Implementation and it's really driving me nuts. I already read everything there is to read in MSDN about this, and read every web post about this sucky API. I am trying to receive file system notifications on windows using ReadDirectoryChangesW, using a...
While doing variadic template programming in C++0x on GCC, once in a while I get an error that says "Sorry, unimplemented: cannot expand 'Identifier...' into a fixed-length arugment list." If I remove the "..." in the code then I get a different error: "error: parameter packs not expanded with '...'". So if I have the "..." in, GCC c...
I have some piece of code that behaves differently under Mac OSX and Linux (Ubuntu, Fedora, ...). This is regarding type casting in arithmetic operations within printf statements. The code is compiled with gcc/g++. The following #include <stdio.h> int main () { float days = (float) (153*86400) / 86400.0; printf ("%f\n", days); fl...
I am using Qt to develop an application and inside we have access to select flash streaming videos like youtube. Is there a way to programmaticly full screen the flash application without requiring interaction from the user? I am using a "QWebView" control. ...
I'm running CodeBlocks on the MingW compiler in an XP virtual machine. I wrote in some simple code, accessible at cl1p , which answers the algorithm question at CodeChef (Well it only answers it partly, as I have not yet included the loop for multiple test cases. However, my problem is, that while running it in debug mode, it gives the ...
Most advice concerning error handling boils down to a handful of tips and tricks (see this post for example). These hints are helpful but I think they don't answer all questions. I feel that I should design my application according to a certain philosophy, a school of thought that provides a strong foundation to build upon. Is there such...
Hi Can somebody give me some tips about storing a lot of data into a file? For example: I'm creating an audio sequencer with C++, and I want to save all the audio sample names (the file paths), info about the audio tracks in the project (name, volume, mute, solo, etc.) and where the samples are placed on the timeline into a file. I re...
