Hi Everyone,
I need help regarding writing c++ application that either starts up 
when windows is  started or runs at the background whiles windows runs 
using the Dev-C++ ide.

Hi people... I was hoping that you could point me some guidance. I want to 
write a little app that captures images and video from my web cam, but i 
can't seem to find any useful sources, as they are all strangely written, 
like private use code.
So, if u please could help me out, I would be very much appreciated

I have done this using the windows API but it was a long time ago and 
that code is long gone. Try doing a search for 'Video Capture Functions 
win32' in google and you should find plenty of useful info. You could 
also try using directx which also has certain functions to capturing 
video. Best of luck with it.

You could try looking into the Virtualdub capture mode code: it supports
windows' video capture interface.

Subject: [Dev-C++] Compile library - linking error
To: dev...@li...
Message-ID: <470...@we...>
Content-Type: text/plain; charset=ascii

Hello all,

I'm currently trying to compile a library from my own, with actually only one function which call a system call (the rest of the files are not shown here): 

DLLIMPORT void DumpNetConnection (void)
{
LPHANDLE net; 

WnetOpenEnum(RESOURCE_CONNECTED,
RESOURCETYPE_ANY,
0,
NULL,
net);
return;
}

However, i have the follwing error at compile time : 

dllwrap.exe --output-def libMyLib.def --implib libMyLib.a dllmain.o -L"C:/Dev-Cpp/lib" --no-export-all-symbols --add-stdcall-alias C:/Dev-Cpp/lib/libmpr.a -g3 -o MyLib.dll
dllmain.o(.text+0x2d): In function `DumpNetConnection':
D:/sources/MyLib/dllmain.c:13: undefined reference to `WnetOpenEnum'


What goes wrong ? I linked to the correct library in project parameter.

Thank's for any help.

Hi all.

Is there any example of how to use gettimeofday() similar functions to
manage time in Dev-C++?

Thanks.

Check out the gnu documentation. It contains all information needed to use
the GNU-based runtime library.

You can also check out the documentation available on the MinGW site.

Or you can just google gettimeofday() - it's a standard function, so you
will get a lot of good hits.

Hi,


Please, I need code of sparse Matriz in C++:
M?thods:
1. MakeDisperseMatrix(nF, nC): Matriz Dispersa vac?a
2. isEmpty(DisperseMatrix): Decide si la Matriz Dispersa est? vac?a
3. getNumberOfRows(DisperseMatrix): Indica el n?mero de filas de la Matriz
Dispersa
4. getNumberOfColumns(DisperseMatrix): Indica el n?mero de columnas de la
Matriz Dispersa
5. getNumberOfElements(DisperseMatrix): Indica el n?mero de elementos
existentes en la Matriz Dispersa
6. printMatrix(DisperseMatrix): Imprime la matriz por filas
7. printMatrizInFile(DisperseMatrix, File): Imprime la matriz en un archivo
(Guardar)
8. getRowOfInsertion(DisperseMatrix, nF, nC): Retorna una referencia a los
predecesores en la fila a insertar.
9. makeNode(object, nF, nC): Crea un nodo.
10. getColumnOfInsertion(DisperseMatrix, nF, nC): Retorna una referencia a
los predecesores en la columna a insertar.
11. InsertInMatriz(DisperseMatrix, nF, nC, object): Inserta "object" en la
fila y columna indicada.
12. getValuePosition(DisperseMatrix, nF, nC): Retorna el valor almacenado en
la fila y columna indicado. Si no existe devuelve 0.
13. getPorcentUsed(DisperseMatrix): Indica el porcentaje de elementos
almacenados.
14. getMaxElements(DisperseMatrix): Indica el n?mero m?ximo de elementos que
pueden ser almacenados en la matriz.
15. addDisperseMatrix(DisperseMatrix1, DisperseMatrix2): Devuelve en
DisperseMatrix1 el resultado de sumar las dos matrices.
16. scaleDisperseMatrix(DisperseMatrix, valor): Retorna la matriz resultante
de multiplicar cada posici?n existente por valor.
17. multDisperseMatrix (DisperseMatrix1,DisperseMatrix2, DisperseMatrix3):
Retorna en DisperseMatrix3 el resultante de multiplicar las matrices
DisperseMatrix1 y DisperseMatrix2(en ese orden).

Thanks and excuse me :(

Is this part of a school work?

If your list is part of an existing library, Google should find the code.
If it is part of a school assignment, you better start coding.

Hi,
I have written a program in Linux.
It opens a file and maps it to memory using mmap and unmaps and closes
the file. I am using a custom written data structure as well in the
program. There is no leak associated with the data structure. But some
ware a big leak is present. (I dont know where) I assume it could be
with mmap and munmap... Because as I open more and more files, the leak
gradually increases to megabytes! but for each mam,p the munmap is
called correspondingly. And the range which I give to unmap is correct.

Where could be the source of problem? Even after the program exit the
memory consumption remains same (not reducted to the program startup
state). I see this with the aid of system monitoring tool..

please help me...

Thanks and Regards,
Lloyd

Hi,

Maybe you should use valgrind to test your program for leaks (compiling with
debugging symbols should help you get a digestable log)

Thank you Jonathan. I tried using valgrind, but my program uses
wxWidgets (a GUI library). The out put of valgrind is unreadable and not
understandable for me :(

It shows lots of lines as output
