Thank you for your replay but that article didn't helped me to solve my issue.

Thank you very much for your help. I solved my issue by setting a default gateway "0.0.0.0". Your explanations helped me to identify and solve this issue.

My raspberryPi subnet may different before changing the IP of Raspberry Pi. The broadcast message will send the message to whole subnet in the phisical LAN. after finding the Raspberrry Pi. We change the IP to use in LAN.

Actually I am using this code for discovering the Raspberry Pi device from an unknown network. We cant set a gateway before findig the Raspberry Pi. After findig the IP we Change the IP of the Raspberry pi to current network then we will communicate to the Raspberry Pi using TCP connection. But the raspbeery pi not sending back my search request.

I can send broadcast message in any network configuration from windows. But my raspberry not working like that.

But how that worked fron windows to linux. I used dynamic IP in my windows and static ip in my raspberry pi. Let me check again.

I have updated the question with my code.

Thank you for this answer.

I didnt find any code to draw gif in ViewPort3D. All the above axamples are in WPF but all are explain to draw in 2D.

Thank you for your helps. I solved the issue. I forgot to reinitialize one array in my application. after reinitialize the array the application worked correctly.

Many thanks.....

My issue is drawing the graphics only once. I added a button to draw another image but that is not drawing correctly. please check my source code from the above link.

I have created a sample application in the above link. That draws the corect image only once. In that application added a button to redraw another image but the image drwan incorrectly. Please check my sample code in the above link

That is too big code.. Could you help me to solve this..
I have uploaded the sample code in this link

When I add -std=gnu++11 the compiler output like this<br>
 <br>
<br>
07:36:03: The process "/usr/bin/qmake-qt4" exited with code 1.<br>
Error while building/deploying project untitled (target: Embedded Linux)<br>
When executing step 'qmake'

I added LIBS += -lrpihw library in pro file


and my main function is

#include <iostream>
#include <rpi-hw.hpp>
#include <rpi-hw driver="" i2c.hpp="">

using namespace std;
using namespace rpihw;

#define ID_I2C_SLAVE_ADDRESS 0x20
#define ID_I2C_DEV_PATH "/dev/i2c-0"

int main()
{

rpihw::driver::i2c objI2C(ID_I2C_DEV_PATH, ID_I2C_SLAVE_ADDRESS);

char *chData;
int iSize=0;
objI2C.write(chData, iSize);

cout << "Hello World!" << endl;
return 0;
}

and my RPi-hw library from https://github.com/Wicker25/Rpi-hw

Do I need to add any more information

I tried to add -std=gnu++11 in Projects->Build Steps-> Additional arguments in Qt creator but that didn't solved the error.

Through a button click or any other event it connect to an application other than web browser using a local IP address and communicate to that application using this connectin. Read data from that application to the web page in browser

I searched in google and got this site for better answer!, If not I will find it for smeware else thanks to your comment

I solved it by adding image plugins to othe systems

I will try it and I think rc.local will be run after run-level specific commands whenever the system is booted.

I solved it by adding mount /dev/sda1 /pendrive in my script for manually mount the pen drive and umount /dev/sda1 after the copying process.

But how? I tried the script in rc.local but the disk is mounting after the rc.local

OK, thanks to your support. I will check the man page

Please bare with me if the question is simple because I am a windows programmer, I am not that much familiar with shell scripting. how I can check this with scripting? and how I can wait for finish mounting?

I put the script in rc.local. rc.local is the last executing script

Thanks for your great solution

How I can stop that thread when no data ?

That waiting thread?

Thanks.........., You are right I forgot to change DAEMON_ARGS="--options args"
start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON -- \
$DAEMON_ARGS \
from my ubuntu systems init.d script. Please put it as your answer I will accept your answer

Many thanks that link helped me to solve the issue....

You are great...
I am giving you 5 and accepting the answer too...

OK, I will do..,Thanks to your valuable advice and support

My child dialogs are showing based on the code in my thread. That I not explained here. I just want to popup my child dialog from thread that will looks like normal model dialog.

In my original code StartTest() doing several processes and showing dialogs during that processes. I don't need to write full code to explain my situation, but with a simple example my question is clear...

Thanks...., that worked

LIBS += -L$$PWD/../../../usr/local/lib/ -lusb-1
Thi path is creating when browse the library from qt creators default library browsing wizard
This solved to me using this way
LIBS += /usr/local/lib/libusb-1.0.so

look below answer for more. He helped me to find the issue...

many thanks.............
It worked when I put like this
unix:!macx:!symbian: LIBS += /usr/local/lib/libusb-1.0.so

I included the library.....

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../usr/local/lib/release/ -lusb-1
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../usr/local/lib/debug/ -lusb-1
else:symbian: LIBS += -lusb-1
else:unix: LIBS += -L$$PWD/../../../usr/local/lib/ -lusb-1

INCLUDEPATH += $$PWD/../../../usr/local/include
DEPENDPATH += $$PWD/../../../usr/local/include

It showing cannot find the library
:-1: error: cannot find -lusb-1
but that is exist in that path

Thanks..., but still have some issues

yes..., create folder dynamically using your service. Because service and our desktop uses different location internally. When we check through explorer that folder exist but when try to find that same location using your service's filedialog you cant find it.

But that is not explaining how to incude another setup with the newly created setup.

Thanks amith...,
I solved it by creating Desktop folder in location C:\Windows\system32\config\systemprofile\Desktop using the code.

I am not sure its a perfect method or not but its worked to me....

I can able to run a windows application from service and able to browse it using folder browser dialog

yes

But when I run in terminal it requires sudo and paasword for communicating to serial device

You mean this will not require sudo and user password for running my application as daemon on ubuntu.

I need like this
http://i.imgur.com/GJAEp.png

I am plotting only to that point and the remaining area will fill with appropritate color

I need the entire temperature distribution and the temperature will vary in each location(I will plot only some particular locations)

please help me to make such an application. If possible with an example

Yes you are right

any one please suggest a better idea to do this...

Yes, I am using Login control

How can I show the table structure. I tried to attach it to SQLServer 2008 but it got some error. Is there any other method to show its content

thanks. I psoted my question in there

sh-3.2# make
make all-recursive
sh-3.2# sudo make install
make install-recursive
test -z "/usr/local/bin" || ./install-sh -c -d "/usr/local/bin"
/usr/bin/install -c avrdude '/usr/local/bin'
Backing up avrdude.conf in /usr/local/etc
test -z "/usr/local/etc" || ./install-sh -c -d "/usr/local/etc"
/usr/bin/install -c -m 644 avrdude.conf '/usr/local/etc'
test -z "/usr/local/share/man/man1" || ./install-sh -c -d "/usr/local/share/man/man1"
/usr/bin/install -c -m 644 avrdude.1 '/usr/local/share/man/man1'

AVRDUDE is written in C. I dont know to edit this code to create a library. I want to know only how I can transfer my created command line utility to another machine. I know the make command creates the binary. how to transfer that from my develpment system to anther

Thanks to your help I solved it

The problem is that
mono-service2 -l:service.lock --debug /usr/local/lib/SampleService1.exe
already running in my machine
when I kill that its worked..

[root@localhost ~]$ mono-service2 -l:service.lock --debug /usr/local/lib/SampleService1.exe &
[1] 1499
[root@localhost ~]$ kill -9 1499
bash: kill: (1499) - No such process
[1]+ Exit 1 mono-service2 -l:service.lock --debug /usr/local/lib/SampleService1.exe
[root@localhost ~]$

thanks..................

is this execute this line echo "Started $APP_NAME"

Yes I written code in start() method to log into a file

I found
mono-service2 -l:service.lock --debug Program.exe
and run the above in terminal. the commands are exucuted well but no output

Surewly I will check your suggestion.., But I need to save the new image

My 5 to your valuable support

Thanks to your help I solved it by removing CALLBACK and my running code is

void *( *managedCallback1)(char **);
void *( *managedStopCallback)();

#define CALLBACK __stdcall
its a calling convetion

I compiled it by removing CALLBACK but that not worked wirth my mono application as a callback

This is my running code on Visual studio. Its working perfectly on mu visual studio but not in Linux

still same problem exist

thaks to your reply, But i know to take control using EditingControlShowing event my problem is to get the editingcontrol without using EditingControlShowing event. In my mono developer EditingControlShowing event is not working I am serching for an alternate method without using EditingControlShowing event

my 5 vote to your answer

many thanks BobJanova its worked to me, One more doubt when I passed integer argument it called the function and c lose the application immediately

I got this following errors
Error 1 error C2059: syntax error : ')' d:\work\testcompilesflow\testeventinc\testlib\testlib\testevent.cpp 10 1 TestLib

I tried your its got some compiler error in int start_something((void*)() f) { ... }

if possible please provide an exaple here is very helpful to me

if possible please provide an exaple here is very helpful to me

Many thanks to your help and suggestion, I solved this by sending a mail to them asking about this issue, now they updated their source with config_windows.h file its working fine now

Yes I checked that command line utility, its working perfectly in my machine but my work is to recompile their existing source code and use its feature in my application

thanks to your reply...,May be possible to make it using any utility. I found some more files with this but don't know how to execute that files

Register your dll in your client machine to get correct path

Use System.IO.Port class for sending signal to serial port. Microcontroller will check this from serial port by its circuit

check project settings tab and change its connection string from there

Change your ReportViewer's report source path to your existing crystal report from other project

Use TextBox2.Focus() method

This will create one interactive desktop for windows service but not with user desktop that the user interacts

Its not an asp.net application,its purely a windows application and please mention your problem

What is your exact problem...?

use single courts only in Text type and remove single courts from number

You r rt...,my up vote to you

Yes you are rt

Is it CrysrtalreportViewer or MicrosftReportViewer?

Need more explanation in your question,What you exactly mean?

Check the speciality of other machines that not working..., If possible create a test application and check sound samples are getting from mike

Its may be due to some linking error or need some small changes in code will fix your problem. I am sure you can use old version VC++ coding in higher versions compare with other languages in windows OS

split your "A,B,C,D" on the basis of "," using string split function in C#
And create A data table using that values,Also pls mention Exact table name,column name etc in Datatable for refering crystal report field

This are some examples creating Crystal report from Dataset
http://www.codeproject.com/KB/cs/CrystalReportNDataTable.aspx
http://www.codeproject.com/KB/cs/CreatingCrystalReports.aspx

Create your report in data table and add to dataset

Many many thanks to your help, but the problem still exist may be due to QAudioInput and QAudioOutput buffer size.

But it's a vector array it will automatically grow its size

I tried that (pcm_databuffer_with_echo,pcm_datalength+phase); to output device in that same function, I can hear the sound but no echo in output sound, What you mean by sum for the 16 bit boundaries, The only change I made in your code is to changed the integer array with vector because I am using a GCC compiler, GCC not supporting this type of declaration

Many thanks to your code. I used code like this I can hear sound but no echo in the output sound, My audio sample rate is 8000 so I called

addecho(data,numSamples,8000,0.9);
to

void MainWindow::addecho(short* pcm_databuffer,unsigned int pcm_datalength,unsigned int phase,double damping)
{
std::vector<short> myvector;

//int* pcm_databuffer_with_echo = new int[](pcm_datalength+phase);
unsigned int i,j;
for(i=0;i<phase;i++)
{
myvector.push_back(pcm_databuffer[i]);
// pcm_databuffer_with_echo[i] = pcm_databuffer[i];
}
for(j=0;i<pcm_datalength;i++,j++)
{="" myvector.push_back(pcm_databuffer[i]="" +(int)((double)pcm_databuffer[j]*damping));
="" pcm_databuffer_with_echo[i]="pcm_databuffer[i]" +
="" (int)((double)pcm_databuffer[j]*damping);
="" }
="" for(;j<pcm_datalength;i++,j++)
="" {
="" myvector.push_back((int)((double)pcm_databuffer[j]*damping));
="" }

="" output="" to="" device
="" short="" *data="(short" *)myvector.data();
="" m_output-="">write((char*)data, pcm_datalength+phase);
//PumpToDevice(pcm_databuffer_with_echo,pcm_datalength+phase);

//delete [] pcm_databuffer_with_echo;
myvector.empty();
}

Copy(string sourceFileName, string destFileName);

May be your C drive permission problem try to save it into another drive

// Create and initializes a new StringCollection.
StringCollection myCol = new StringCollection();

// Add a range of elements from an array to the end of the StringCollection.
String[] myArr = new String[] { "RED", "orange", "yellow", "RED", "green", "blue", "RED", "indigo", "violet", "RED" };

myCol.AddRange(myArr);
Properties.Settings.Default.MySettings = myCol;
Properties.Settings.Default.Save();

use system.collections.specialized.stringcollection in settings data type

like echo to my output sound, But echo is repeating sound, I need only the second sound in echo

Use session variable instead of cookies
