Progressbar

you mean like a progressbar?:

private: System::Windows::Forms::ProgressBar^ progressBar1;

progressBar1 = (gcnew System::Windows::Forms::ProgressBar());

this->progressBar1->Minimum = 0;
this->progressBar1->Maximum = 1000;
/*(this way youll get a bar wich goes from 0 - 1000;
with every 10 points a block on the screen) (progressbar is default
divided in 100 parts). use the Preferences to change this

to use it:*/
for(int i = 0;i<1000;i++){
progressBar1->Value = i; // or: progressBar1->value++;
Thread::Sleep(100);
}

this way your progressbar will slowly count up to 1000;
