I found the following link to a c# form application to control an RC car using a USB port. The project above requires both the Microsoft Robotics development software and a circuit board known as the Phidget interface kit. A more low-level way of communicating with the remote control is through the parallel port. Here’s a c# project that describes using the inpout32.dll c compiled library to communicate with the parallel port Additional references A location for highrez.co.uk. They keep maintaining the original inpout32.dll (and even include a 64-bit version) Tags.
We can easily program the parallel port in DOS. But as we know, DOS programs have their own limitations.

So, if you want to move from DOS to Windows, go through this article. This is an introduction to program the parallel port in VC. You need not have much knowledge about VC. This article is designed for one who know basics of parallel port and beginners of VC. If you don't know anything about parallel port, read my first article '. There you get basic information about parallel port and programming the port in Turbo C or Borland C.

Now, you are knowing the pins and registers of parallel port. You know how to access them in DOS. If you want to run your program in Windows 95 or 98, you are having access to the port in the similar way.
You need to know how to use dialog boxes and windows materials with it. But your program should also run in Windows XP, NT or higher versions, then there is another issue. Higher versions of Windows do not allow to access the hardware directly for security reasons. But still, there are ways, I will explain later.
First we will start programming which will work only in lover versions of Windows. Direct Access: If you want to program the port in VB, there is no direct access to the port. Still you can access the port using DLL files created with VC.
You can use the next method. If you are familiar with Visual C, then create a dialog based application named ParallelPort and skip this section, go to. Creating the application:. Start Visual C, Select File- New.
In the tab 'Projects', Select 'MFC AppWizard (exe)', give project name as 'ParallelPort' and click OK. In the next window, select radio button ' Dialog based' and click next leaving all other options default. Click Finish, then OK to get a window with two buttons and one sentence 'TODO: Place Dialog controls here.' , select and delete that sentence.
Click to select the button 'Cancel' and delete it. Right click on button labeled OK, select Properties from the drop down menu. Change the value of Caption to '&EXIT' from 'OK'. Resize the dialog box to get a window as shown below. If you run the application by clicking this icon:, it should give 0 errors and 0 warnings, and you will get the following window. Figure(2.1) Adding controls: Now, you should see a tool bar as shown here, it is called Control toolbar.
If not, select it from view menu-toolbars. Icon marked here with red color is the Check Box. If you click the check box icon and draw in the window, You will have the check box placed in the window. You need to place 17 such check boxes in the window. You can use copy-past to make your work easy. After that, Group then using 3 group boxes.
Group box icon is there above the check box in the figure. After doing this much, your design should look like figure(2.3). So, re arrange your dialog components to look like that. Again run the application and make sure that there is no error. Figure(2.2) Figure(2.3) Next, right click on the Group Box labeled Static and go to properties.
Change the captions to Data, Status and Control respectively. Right click on the first Check box Check 1, Change the caption to 'Pin 2' and ID to IDCPin2. Similarly change the captions of check boxes in data group to Pin 2 to Pin 9; status port Pin 10, Pin 11, Pin 12, Pin 13 and Pin 15; Control Port Pin 1, Pin 14, Pin 16 and Pin 17. Change the ID's correspondingly(IDCPin2, IDCPin3.). Window designing is over.
Next part is coding. We have placed some controls in the dialog box. To get the values of these controls, we need to have variables associated with then.
To do that, right click and select 'ClassWizard' from drop down menu. Select tab 'Member Variables'. You will get a list of Control IDs. Select each IDs separately and click Add Variable. Type variable name as mpin1. Mpin10, mpin11. And retain Category Value and Variable type BOOL.
Refer following figure. Figure(2.4) In the Workspace, Select ClassView tab, under ParallelPort classes, right click on CParallelPortDlg, click Add Member Function. Give function type as void and function name as UpdatePins. It will take you to the new function created. Edit the code as follows.
#define DATA 0x378 #define STATUS 0x379 #define CONTROL 0x37a The function CParallelPortDlg::UpdatePins is used to display values of all pins initially. Here, we have used inp function to get the values of registers associated with the ports. inp(PORT) will return the data present in PORT. Depending on the status of the pins, we are making Check boxes checked or unchecked. When we change the value of member variable and call the function UpdateData(FALSE), the values in the member variables will be updated in the corresponding controls in the window. Similarly if you call UpdateData(TRUE), Values which are there in the corresponding controls will sit in the member variables.
Here, The values from the variables should be updated in the window. So, UpdateWindow(FALSE). If you have read my first article, you will understand all other things done here. To make run this code when the dialog is initialized, we need to call it.
So, go to function OnInitdialog in the file CParallelPortDlg. (In the class view tab of the workspace, under ParallelPort Classes, expand CParallelPortDlg, you will get the function name, double click it.) Add the following code to it. This code will call the function UpdatePins and set a timer to scan the port pins. You can change the second parameter to change the frequency at which ports are needed to be scanned. I have used 200 milli seconds.
outp(CONTROL, 0xDF) will reset the control register bit 5 low so that data pins will act as output. outp(PORT, DATA) sends the byte DATA to the address PORT. Short stdcall Inp32(short portaddr); void stdcall Out32(short portaddr, short datum);. Where ever inp comes, change them to Inp32 and where ever outp comes, change them to Out32. Copy DLL file inpout32.dll and lib file inpout32.lib got by compiling the source code available at logix4u.net to the project folder.
From project menu, select settings, go to tab link, in object/ library modules write inpout32.lib. Now your program should run without any errors. If you have any comment, feedback and suggestions, please send an e-mail to or Also Read: - -.
