testing a wxwidgets multithreaded application

hi all i have the following multithreaded wxwidgets application and i am testing it , i need the output as the first thread should output the values from 0 to 0xFFFFFFFF and then the second thread and so on..please help




#include <iostream>
#include <cstdlib>
#include <cstdio>
#include <wx/thread.h>
#include <wx/log.h>
#include <wx/app.h>
using namespace std;
static wxCriticalSection * critsect = NULL;

class MyThread : public wxThread {
public:
    MyThread(unsigned int& c, wxThreadKind kind = wxTHREAD_JOINABLE);
    virtual ~MyThread();
protected:
    virtual ExitCode Entry();
private:
    unsigned int& counter;
};

MyThread::MyThread(unsigned int& c, wxThreadKind kind) : wxThread(kind), counter(c) {
}

MyThread::~MyThread() {
}

wxThread::ExitCode MyThread::Entry() {
    for (;;)//make this stuff inside the critical section too
    {
        critsect->Enter();
        if (counter == 0xFFFFFFFF) {
            critsect->Leave();
            break;
        }
        ++counter;
        critsect->Leave();
    }
    return 0;

    //only one thread does operation on critsect
}

int main(int argc, char** argv) {
    unsigned int uicounter = 0;
    if (argc || argv) argc;
    wxInitializer initializer;

    if (!initializer) {
        fprintf(stderr, "Failed to initialize the wxWidgets library, aborting.");
        return -1;
    }
    critsect = new wxCriticalSection();
    if (critsect == NULL) {
        fprintf(stderr, "Failed to create the critical section object, aborting.");
        return -2;
    }
    MyThread *mt = new MyThread(uicounter);
    MyThread *mt1 = new MyThread(uicounter);
    MyThread *mt2 = new MyThread(uicounter);
    MyThread *mt3 = new MyThread(uicounter);
    if (mt || mt1 || mt2 || mt3) {
        if ((mt->MyThread::Create() == wxTHREAD_NO_ERROR) || (mt1->MyThread::Create() == wxTHREAD_NO_ERROR) || (mt2->MyThread::Create() == wxTHREAD_NO_ERROR) || (mt3->MyThread::Create() == wxTHREAD_NO_ERROR)) {
            mt->Run();
            mt1->Run();
            mt2->Run();
            mt3->Run();
            if (mt->IsRunning() == true) {
                {
                    cout << uicounter << endl;

                }
                wxThread::Sleep(1000);
                mt1->Delete();
                mt2->Delete();
                mt3->Delete();

            } else if (mt1->IsRunning() == true) {
                {
                    cout << uicounter << endl;
                }
                wxThread::Sleep(1000);
                mt->Delete();
                mt2->Delete();
                mt3->Delete();
            } else if (mt2->IsRunning() == true) {
                cout << uicounter << endl;
                wxThread::Sleep(1000);
                mt1->Delete();
                mt->Delete();
                mt3->Delete();
            } else if (mt3->IsRunning() == true) {
                cout << uicounter << endl;
                wxThread::Sleep(1000);
                mt1->Delete();
                mt2->Delete();
                mt->Delete();
            }
        }
    }
    delete mt;
    delete mt1;
    delete mt2;
    delete mt3;
    return 0;
}

The Output is :-

13:27:47: Error: Can not resume thread 0 (error 6: the handle is invalid.)
