Suppose I want to write my own preprocessor.
So I want something like this:
all *.cpp and *.hpp (even the included ones), before they go to g++, they go:
file --> my preprocessor -> g++
Is there a easy way to do this in the LLVM framework? i.e. to add in a stage that says: "after you load up the source file, pipe it through this program before compling it" ?
Thanks!
Hello,
I am just wondering why programmers who program in C++ for windows always use Visual Studio 6 instead of Visual Studio 2008?
Isn't the compiler in 2008 much better than the one in VS6?
The reason I ask as I have used many sdk's that are always written in VS6?
Many thanks,
Steve
I have a ByteInputStream, created from a Socket in Java. The connection is to a simple web server that uses chunked transfer encoding. The web server does in fact work in normal browser. But in my program, I am attempting to read, I read the first first bytes (some 5kb of data). But each read after that returns 0 bytes read. Isn't it supposed to block until it can read?
The error-Warning: sqlite_query() [function.sqlite-query]: attempt to write a readonly database is coming whenever i try to insert values into a sqllite 1.1 database thru php program.
php version is 5.2.
Quick and simple question.
There are examples online about achieving in-memory gzip compression with zlib (C++) WITHOUT external libraries (like boost or such)?
I just need to compress and decompress a block of data without much options. (it must be gzip as its the same format used by another mine C# program (the data is to be shared))
Tried to search to no avail...
Thanks!
the requirement is to disable all the ports of the pc when my program run on particular machine how is it possible need guides???
sorry i think my question was confusing by all ports mean PS 2 USB parallel ports etc.
simply no one can interact with pc from any path but with ether net card it should be enabled.
Java's jar file format builds off of the zip file format, and supports compression of the class files inside it. When and how does the JVM decide which class files to uncompress and pull out of the jars on its classpath? Is the process dynamic and done at runtime as classes are needed, or are they all uncompressed up front before the program actually runs?
Hi all:
I'm looking for an accurate way to measure memory usage of a C# program under Windows operating system. I'm using Visual Studio for programming my code and I want to know its time consuming for performance. Really, I tried to use the Task Manager, but I do not get an accurate measurment.
Please, if any one know an accurate way to measure the memory consumption, please help me and thanks alot
Hi
I am reading a file using File.ReadAllText("filename.txt"). This file is located in very same folder where the .exe file is located (c:/program files/installation folder). But windows app looks into System32 folder for this file by default.
**I don't want to hard code the path of the file.
I need to write a custom batch File renamer. I've got the bulk of it done except I can't figure out how to check if a file is already open. I'm just using the java.io.File package and there is a canWrite() method but that doesn't seem to test if the file is in use by another program. Any ideas on how I can make this work?

Does any one has succesfully created a unit or Delphi 7 class to upload tweets to the TWitter web site ?
I would like to be able to add tweets from within my Delphi program.
I have a sinatra service foo.rb
To run it I on a different port I would type "ruby foo.rb -p 5000".
While the program is running I would like to be able to get the port (in this case 5000) and other information. Is there a way to get info like this while the app is running?
Thanks
In C# WinApp, How Can I add both Text and Value to the items of my comboBox?
I did a search and usually the answers are using "Binding to a source".. but in my case I do not have that source ready in my program...
how can I do something like this:
combo1.Item[1] = "DisplayText";
combo1.Item[1].Value = "useful Value"
I'm developing a program that would require huge amount of memory, and I want to catch when out-of-memory exception happens. I had heard this is not possible to do, but curious if there is any development on this end.
I'm doing a little program and I want to distribute using this recipe:
single directory with _main_.py in it
zip this directory and echo #!/usr/bin/env python\n file.zip
making it executable
The problem is that in this package I have also extra files (I'm using pygtk toolkit and I need images and ui xml files). When I try to access these files I have the error that the resource is unavailable (the path that I'm trying to open is something like file.zip/gui/gui.ui ).
How can I handle this situation?
Hi,I have a DataSet with some Datatables and I am saving this DataSet as XML file (C#) ..is there any way to load only some parts of this XML file into the DataSet when I start my program instead of loading all the file ?
I am developing a WPF client program for some websites. It uses XML database. I am new to XML. Would someone please explain how to create,append(Most important),edit,read&encrypt XML file. It is a big question,i know . But, it is urgent.Have to complete the work ASAP. Searched in the internet, not getting correct info.
After profiling a large game playing program, I have found that the library function rand() is consuming a considerable fraction of the total processing time. My requirements for the random number generator are not very onerous - its not important that it pass a great battery of statistical tests of pure randomness. I just want something cheap and cheerful that is very fast. Any suggestions?
How is the scope of a variable/identifier maintained in the symbol table of a c/c++ compiler.
Please suggest some good links and books to know the how compiling process of c/c++

I have a windows application,sometimes in windows 7(also ultimate with administrator user) and vista to run it i need to right click and run it as administrator,I know the reason is attempt to access to system directories from my program,how i can solve this problem,is
net user administrator /active:yes that using for enabling the real aministrator account solve the problem? if no what should i do ! Thx
I'm conflicted between a "read once, use memory+pointers to files" and a "read when necessary" approach. The latter is of course much easier (no additional classes needed to store the whole dir structure), but IMO it is slower?
A little clarification: I'm writing a simple build system, that read a project file, checks if all files are present, and runs some compile steps. The file tree is static, so the first option doesn't need to be very dynamic and only needs to be built once every time the program is run. Thanks
Is there any way of organizing a icon collection so that it easier to find needed icons?
For example:
the program needs a save icon
there are 5 icons collections on your HD that have a save icon and there are 5 more collections that don't have a save icon (but you don't know that)
do you browse through each icon collection?
run a search (assumes files are named consistently)?
Would it be ideal to have some sort of organized directory (printable?)?
