ok everyting works this->backgroundWorker1->DoWork += gcnew System::ComponentModel::DoWorkEventHandler(this, &fuck::backgroundWorker1_DoWork); this->backgroundWorker1->ProgressChanged += gcnew System::ComponentModel::ProgressChangedEventHandler(this, &fuck::backgroundWorker1_ProgressChanged); this->backgroundWorker1->RunWorkerCompleted += gcnew System::ComponentModel::RunWorkerCompletedEventHandler(this, &fuck::backgroundWorker1_RunWorkerCompleted); was indeed missing

private: System::Void backgroundWorker1_DoWork(System::Object^ sender, System::ComponentModel::DoWorkEventArgs^ e) {

while (true)
{
	if (backgroundWorker1->CancellationPending) //if it was cancelled
	{
		e->Cancel = true;
		
	}
	if (progressBar1->Value == progressBar1->Maximum)  //if the progress bar value reached maximum

Valuse==progressBar1->Maximum does not stop DoWork this "Maximum"

	{
		
	}
	Beep(1500, 100);
	backgroundWorker1->ReportProgress(50);  //reporting progress
	Sleep(500);   //wait for 1 second
}

}

now i really got everything i needed thanks for help

not relevant as i wanted to replace that method anyway my man ;P but yes i forgot about that

what i didnt understand a thing you just wrote and i would really appreciate if you could simplify and maybe show me some example me big noob i started programming like 2 months ago for real and english is not my first language

private: System::Void start_Click(System::Object^ sender, System::EventArgs^ e) {
backgroundWorker1->RunWorkerAsync(1);
this->start->Visible = false;
}
private: System::Void backgroundWorker1_DoWork(System::Object^ sender, System::ComponentModel::DoWorkEventArgs^ e) {

while (true)
{
	if (backgroundWorker1->CancellationPending) //if it was cancelled
	{
		e->Cancel = true;
		
	}
	if (progressBar1->Value == progressBar1->Maximum)  //if the progress bar value reached maximum
	{
		
	}
	Beep(1500, 100);
	backgroundWorker1->ReportProgress(50);  //reporting progress
	Sleep(500);   //wait for 1 second
}

}

private: System::Void cancel_Click(System::Object^ sender, System::EventArgs^ e) {
backgroundWorker1->CancelAsync();
this->start->Visible = true;
}
private: System::Void backgroundWorker1_ProgressChanged(System::Object^ sender, System::ComponentModel::ProgressChangedEventArgs^ e) {

	   progressBar1->Value += e->ProgressPercentage;  //rising the progressbar's value

   }

private: System::Void backgroundWorker1_RunWorkerCompleted(System::Object^ sender, System::ComponentModel::RunWorkerCompletedEventArgs^ e) {
this->start->Visible = true;
progressBar1->Value = 0; //reseting value

if (e->Cancelled)    //Messages for the events
{
	MessageBox::Show("kiss my ass ");
}
else
{
	MessageBox::Show("eat my shit ");
}

}
};
}

^ | | this shit above is from Add new comment | Free Source Code[^] where i found one and only tutorial how to use background worker in c++ an not in c# to this moment i was only using some formulas from it but now i coppied everything AND..... it's not working progress bar is not updating i wasn't even sure if it works untill i added beep and it works but not quite not updating this fucking progress bar cancel button doesn't work (but it kinda does) i'm really on the edge right now im this >< close to lose my shit

yes i did :^) , only left workerSupportsCancel to false because i don't really need this. I have abandoned that project couple days ago and now with another one i still have problem with the same thing

private: System::Void backgroundWorker1_DoWork(System::Object^ sender, System::ComponentModel::DoWorkEventArgs^ e) {

	for (int day = 1; day <= 31; day++)
	{
		Beep(1500, 200);
		Sleep(500);
		backgroundWorker1->ReportProgress(day);

	}

}
private: System::Void backgroundWorker1_ProgressChanged(System::Object^ sender, System::ComponentModel::ProgressChangedEventArgs^ e) {
progressBar1->Value += e->ProgressPercentage;
this->days->Text = (e->ProgressPercentage.ToString() + " day");
}
private: System::Void backgroundWorker1_RunWorkerCompleted(System::Object^ sender, System::ComponentModel::RunWorkerCompletedEventArgs^ e)
{
MessageBox::Show("next");
}

My backgroundWorker1->RunWorkerAsync(); is in form_load so it should start when i open it and still no success with this m*th*r******* label update. There is also no beeping indicating this shit even works

Quote:

I think i'm going to quit this shit start farming, somewhere nice with no internet access

public: System::Void joke_Load(System::Object^ sender, System::EventArgs^ e) {
bgwork->RunWorkerAsync();
}
public: System::Void labb_Click(System::Object^ sender, System::EventArgs^ e) {
Beep(2500, 100);//label beeping
}
public: System::Void bgwork_DoWork(System::Object^ sender, System::ComponentModel::DoWorkEventArgs^ e)
{

for (i=10; i >=0; i--)
	{
		bgwork->ReportProgress(i);
		Sleep(1000);
		Beep(1500, 100);
	}
e->Result =i;
}
public: System::Void bgwork\_ProgressChanged(System::Object^ sender, System::ComponentModel::ProgressChangedEventArgs^ e)
{
	this->faketimer->Text =e->ProgressPercentage.ToString()+"";
}
public: System::Void bgwork\_RunWorkerCompleted(System::Object^ sender, System::ComponentModel::RunWorkerCompletedEventArgs^ e)
{
	MessageBox::Show("ok", "ok", MessageBoxButtons::YesNo, MessageBoxIcon::Warning);

}

label "faketimer" still has default text this piece with converting to string is something i saw in tutorial i guess it will not work because my values are decrementing

i'm trying to update label named "timer" with values from my prank function

#pragma endregion
void prank()
{
Beep(1500, 200);
for(i=10;i>=0;i--)
{
Sleep(500);
this->timer->Text =i+"";
Beep(1500, 200);
}
}
private: System::Void joke_Load(System::Object ^ sender, System::EventArgs ^ e) {
TopMost = true;
backgroundWorker1->RunWorkerAsync(1);
}
private: System::Void button1_Click(System::Object ^ sender, System::EventArgs ^ e) {
joke^ nokno = gcnew joke();
nokno->Show();
//
}
private: System::Void label1_Click(System::Object ^ sender, System::EventArgs ^ e) {

}
public: System::Void backgroundWorker1\_DoWork(System::Object ^ sender, System::ComponentModel::DoWorkEventArgs ^ e) {
	prank();
}
public: System::Void backgroundWorker1\_ProgressChanged(System::Object ^ sender, System::ComponentModel::DoWorkEventArgs ^ e)
{
	this->timer->Text = i + "";
	Beep(1500, 200);
}

private: System::Void start_Click(System::Object^ sender, System::EventArgs^ e) {

}

it's not supposed to be real timer or anything i just want it to happen in the background so i can make another actions. the first Beep indicates for me that it starts but second one not really also i can't manage to use

backgroundWorker1_ProgressChanged

as you can see i have pitifully tried updating it ?traditional? way. i'm learning to code by myself (also english so sorry :^) ) and this is my first attempt to use background worker i could really use some suggestions and please keep them simple after all i'm simpleton?

i could use some tip about simplifying this code:

class Pojazd
{
public:

virtual void buduj()=0;

};

class Sedan : Pojazd
{
private:
string typ="Sedan";
public:
string marka;
string model;
int hp;//horse power
double v;//pojemnosc silnika
int cena;
virtual void buduj()
{
cout << marka << " " << model << " " << endl;
cout << "Typ nadwozia: " << typ << endl;
cout << "Dane Techniczne: " << endl;
cout << "-" << hp << " KM" << "\n-Silnik: " << v << "L" << endl;
cout << "Cena " << cena << "\nmiesieczna rata " << cena / 12 << endl;
}
Sedan(string nadwozie)
{
nadwozie = typ;
}

};

class Hatchback : Pojazd
{

string typ;

public:
string marka;
string model;
int hp;//horse power
double v;//pojemnosc silnika
int cena;
virtual void buduj()
{
cout << marka << " " << model << " " << endl;
cout << "Typ nadwozia: " << typ << endl;
cout << "Dane Techniczne: " << endl;
cout << "-" << hp << " KM" << "\n-Silnik: " << v << "L" << endl;
cout << "Cena " << cena << "\nmiesieczna rata " << cena / 12 << endl;
}
Hatchback(string typ)
{
typ = typ;
}
};

int main()
{
w:
int switch_on;
cout << "1.Sedan\n2.Hatchback"<> switch_on;
switch (switch_on)
{
case 1:
{
cout << "1.Mercedes\n2.BMW\n3.Audi\n";
cin >> switch_on;
switch (switch_on)
{
case 1:
{
Sedan Mercedes("Sedan");
Mercedes.marka = "Mercedes";
Mercedes.model = "A klasa";
Mercedes.hp = 145;
Mercedes.v = 2.1;
Mercedes.cena = 156000;

        Sedan\* wsk\_sedan;
        wsk\_sedan = &Mercedes;
        wsk\_sedan->buduj();

    }
    case 2:
    {
        Sedan BMW("Sedan");
        BMW.marka = "BMW";
        BMW.model = "d531i";
        BMW.hp = 166;
        BMW.v = 2.5;
        BMW.cena = 188770;

        Sedan\* wsk\_sedan;
        wsk\_sedan = &BMW;
        wsk\_sedan->buduj();
    }
     
    }

}
break;
case 2:
{

}
    break;
}





return 0;

}

i could continue with constructing this switch case tree sort of thingy but i'm wondering if i
