Are you just wanting to change the output directory? Look into the project settings.

Correct me if I got you wrong.

Hi Rajesh,
Thanks for ur reply.

Intially , i have 2 project in my solution (1)Win32 Application- AppServer , (2) Setup project .
from this i created an MSI and installed my AppServer.exe to local & remote machine.

Now my requirement is , i have to register my application as windows services, so i have added one more project as WindowsService1
from VC++->Windowservice option,

i have builded all the 3 project and installed my Setup project , i tried to start my exe from services.msc, but here i am able to see

Servicename: Service1
Path: C:\testing\windowsService1\WindowsServcie1.exe
not C:\testing\AppServer\Appserver.exe

I need my Servicename as : Service1
& Path as C:\testing\AppServer\Appserver.exe

i mean my service has to point to my Win32 application exe.

Plz thru some light on this
Your help much appreciated.

I'm not sure if you need a third project, just for the sake of registering your executable as a windows service. In my opinion, the setup must have provision to register a program being installed as a service. Have you checked on that?

Yes Rajesh, i am able to install a service thru setup project (if i select windows service project template) ,

THE PROBELM IS:

i have

solution :testing
project1: windowsservice1 (Windowsservice project)
project2: AppServer (Win32 application project)---> this is my main application AppServer.exe
project3: ServerSetup (SetupProject)

If i do run my MSI file from ServerSetup, its installing AppServer.exe to C:\program files\AppServer\AppServer.exe
and in Services i have only Servicename: AppServer , Path :C:\program files\AppServer\WindowsService1.exe (instead of AppServer.exe)

i hope nw i expained correctly Smile | :)

Try the devenv[^] command from Microsoft. Alternatively you can create your own makefile[^] and use that.

Check if you added to the Visual Environment, as a first step, the correct configuration for external libreries:

* Open Visual
* Choose menu "Tools" and select "Options"
* In "Projects and Solutions" and go to "VC++ Directories"
* Show directories for "Library Files" and "Include files"
* Add your libraries and includes you need for your project.

This is the most common error while linking Wink | ;)

Hello all,

I´m trying to multithread an application by using CreateThread function. So far I´ve done the following:

//Here I initialize the Thread
LPDWORD iID;
HANDLE hThread; // array of thread handles
hThread = CreateThread (
            0, // Security attributes
            0, // Stack size
            (LPTHREAD_START_ROUTINE)OpenCVWin32::Form1::Threadi,
            NULL,
            CREATE_SUSPENDED,
            iID);
}

//Called function
static DWORD WINAPI Threadi()
{
	System::Windows::Forms::MessageBox::Show("Hi there!");
	return 0;
}

When I launch the application, the thread is not created, as I cannot go inside the Threadi function. I´m right now using VC++ 2008. Does anyone has a suggestion on why this could be happening?

Thanks

CREATE_SUSPENDED,

This is the problem. If you use this attribute then the thread is created in suspended state. More Info Here[^]

If you want the thread to start as soon as you launch the application, don't create a thread in suspended state. If you want to create in suspended state, then you can use ResumeThread() function.

Thank you HimanshuJoshi. I was reading in zig-zag the doc, so I didn´t realize about it.

I still have some problems. After changing it, I have a problem accessing the memory. This is the error I got (after using 0 instead of CREATE_SUSPENDED,:

<br />
Unhandled exception at 0x003628c2 in OpenCV Win32.exe: 0xC0000005: Access violation reading at position 0x0000000c.<br />

I´ve been thinking about sending the 3 parameter as
(LPTHREAD_START_ROUTINE)&OpenCVWin32::Form1::Threadi,

But I got a different error:

error C3374: Address of "OpenCVWin32:: Form1:: Threadi" can only be adopted if a delegate instance is created.

I will appreciate any suggestions. Thank you Smile | :)

LPTHREAD_START_ROUTINE is defined as:

typedef DWORD (WINAPI *PTHREAD_START_ROUTINE)(
LPVOID lpThreadParameter
);
typedef PTHREAD_START_ROUTINE LPTHREAD_START_ROUTINE;

so, your thread function is to be:

static DWORD WINAPI Threadi(LPVOID lpThreadParameter)
{
System::Windows::Forms::MessageBox::Show("Hi there!");
return 0;
}

Hello!

Thank you! I didn´t though that passing the parameters will be compulsory. But nevermind, I put it on my code.

If you're using MFC, you *must* use AfxBeginThread to begin a worker thread. If you are using Win32, you should be using _beginthreadex to create a thread.

CreateThread is an API and that will even create a thread if you're linking to the single threaded version of the CRT (which will inevitably lead to disaster).

If you're writing managed code, take a look at Thread.Start method in the documentation. Basically, I want to emphasise that there's no sane reason or excuse to use CreateThread from your code. There are safer and sane alternatives.

Subscript requires array or pointer type

23-Nov-09 5:15

Hello,

I finally found the problem. The code for the Thread Function was inside the ref class, so that made it managed code. I finally put outside it, and now is working fine Smile | :)

Thank you.

I was having this initially
double* m_Value [4];
I want to redefine it differently.So what I did is

typedef vector <double> DOUBLE_VECTOR;
DOUBLE_VECTOR DoubleVec;
vector <double_vector> m_Value;

Above I did in .h file

Now I initialize it in constructor I mean .cpp file

DoubleVec.resize (10,0.0);
m_SplitArrPtr.resize (5,DoubleVec);

Till here I thing I have done fine.

Issue:
Now there is a function whose defination is somewhat like this

static void Func (double& ObjData,void* DataPtr);

In above function I have to fill the ObjData by DataPtr OK

So I did this

void ClassName::Func (double& ObjData,void* DataPtr)
{

int RowIndex = 0; // row index
int ColIndex = 0; // column index

//copy data to existing structure
for (RowIndex;
RowIndex < 5;
RowIndex++)
{
for(ColIndex;
ColIndex < 10;
ColIndex++)
{
ObjData [RowIndex][ColIndex] = DataPtr->m_Value [RowIndex][ColIndex];
} //for ColIndex
} // for RowIndex

}
But I am facing an error

"error C2109: subscript requires array or pointer type"

So please help me out that how I will be able to fill the ObjData.

Please, read the posting guidelines and format your code properly, it is almost unreadable.

ObjData is a double, not an array so you can't use it like an array. DataPtr is a pointer to void, so if you want to access its content, you first have to cast it to something appropriate. Why are you using a pointer to void here ?

ObjData is a double &. To use two subscripts (ObjData[RowIndex][ColIndex]). You have to have a two dimensional array such as double **ObjData.
