Until the question remain in theese exact term, there can be no answer: "I have to go faster than light" "It is not possible in this universe" "I have to do it whatever it cost!" The proper answer is to change the universe! In your context, it means that motor steps and speed sholud be controller by a different processor (probably a microcontroller) that should have no operating system on it, but must just execute a simple program that manage the steps based on some "variable" you have to set from the extern, and that receive some information fom the "extern" to set those variables. And the "Extern" can be a PC taking with the microcontroller (may be via serial, or via ethernet) in getting/setting the values the cotroller use as parameters to govern the engine. Note that windows high resolution timers cannot help, since they exist to measure time, not to control process switching, that is never granted to happen in constant timeslot. What happens if you open Otlook or Word or Powerpoint while the motor is running ? 2 bugs found. > recompile ... 65534 bugs found. :doh:

create a public property in a form and by setting its property you can change the value //declaring property in CForm1 private: int abc; public : property int ABC { int get() { return abc; } void set(int value) { abc = value; } } // using property in CForm2 #include "Form1.h" CForm1^ frm = gcnew CForm1(); frm->ABC = 123; Nigah M Manzoor

i got my answer it is helpfull thanx... --we were great,and we will rise again-- --------Don't forget-------------------- --always comes daylight after night-----

Well unless your code is doing the processing you can't stop it without terminating the worker thread waiting on the process, which is not recommended. led mike

Try some of the following depending on your compiler and environment. standard: exit(-1); Microsoft: ExitProcess(-1); TerminateProcess(GetCurrentProcess(),-1); Microsoft Window: PostMessage(WM_CLOSE,0,0);

Ohhh it's a managed c++ app.  You're in the wrong forum to start with. The TextBox class has a property called Text.  If you have a TextBox object for the edit control, you can get its text with this property: System::Windows::Forms::TextBox ^MyTextBox = ...; ... int MyInt = Convert::ToInt32(MyTextBox->Text); Mark *edit* fixed wrong operator Last modified: 11mins after originally posted -- Mark Salsbery Microsoft MVP - Visual C++ :java:

For instance: void display (int *p, int size0, int size1) { int i, j; for (i = 0; i < size0; i++) for (j = 0; j< size1; j++, p++) printf("%-5d \n", *p ); } int main() { int a[2][5] = {{3, 8, 7, 6, 10}, {6, 16, 14, 12, 20}}; display((int *)a, 2, 5); } If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

Don't know what you intend making, but the web page you quoted is straight forward. However, here is a blog that uses the parallel output to drive two stepper motors attached to an etch-a-sketch. http://zedomax.com/blog/tag/uln2803/[^].

i got some information, but finding it was very hard. it has six wires. two reds, two yellows and two grey. Grey1 --- --- Grey2 ¦ ¦ ¦ ¦ Red1 --- --- Red1 (reds are common) ¦ ¦ ¦ ¦ Yellow1 --- --- Yellow2 i cannot understand which wire has to be connect to the uln's first output and second etc. thanks for your answer. :)
