Yes, you are missing 4 more sliders.
ROVIO wrote: or is it possible to edit the app to be able to have 8 sliders controlling 8 servo's?
The source code would need to be modified, it appears the application was designed to only operate 4 servomechanisms. The reference to the number 8 in the website you provided is most probably referring to DB25 data pins 2 through 9[^].
ROVIO wrote: If anyone is good with programming, please have a look at the source code provided in the link, and see if you can get the app to work with 8 sliders.
Unfortunately the software you are using was developed with Delphi3 which was released way back in 1997. I have not developed anything with Delphi in many years. I *do* however own a copy of Borland Delphi 3 which I havent used in nearly a decade.
Hmmm, I will volunteer to modify the application for nostalgic purposes. You will have to wait until I get off work and I will make an attempt.
Best Wishes,

Good day David
I will appreciate that alot.
Could you please create an .exe file when you are done, because at the moment i have Visual Studio 2008 Standard edition installed, and i have oppened a few source codes, but have no idea what to do with the code to create an .exe file (run file)yet. 
Thank you so much
Regards,
Riaan Deyzel

Visual studio won't compile Delphi. You need the Borland compiler to do that (dunno if there's a free version or not).

Riaan,
It was an adventure and brought back some old pascal memories. I modified the servo application and hopefully added the ability to command 8 servos. I have not tested it at all, I simply modified the source code. Perhaps you should say a short prayer before running it.
You can download it here:
Modified Servo Commander[^]
I can only provide limited support. If you need any additional bug fixes or modifications to the application we can discuss the issue through e-mail. I have included the modified source code and also the porttalk drivers.
Good Luck,
-David Delaune

Good Day David
I have downloaded the .zip file & run the servo.exe file, It looks very good.
I will test the app on the servo,s today after work.
Quick question - Where you put the Hardware Address in the app are those 3 choices 3 different Parralel ports (eg LPT1 / LPT2 /LPT3)
Can i just run the SERVO.exe file, or do i need to do anything something else to run the app.
It works fine here at the office.
Spotted a minor bug in app - when i add the channels 1 - 8 & a few entries down in the table on the right & hit play the blue highlighted box does not seem to move down the list to the next channels down the line & the channels on the left does not move to the corresponding value when it goes down the list.
I will let you know the results tomorrow.
I feel like a kid with a new toy with this app you created. 
I have to say, you did a great job,I an very impressed.
Thank you very much.
My personal e-mail address is riaan.deyzel@gmail.com for direct correspondance.
I do not have your e-mail address, but if you send me an e-mail i will reply to that address.

Good day David
I have not heard from you in a long time, looks like Code project & your job is keeping you very busy.
I would just like to see if you made any progress with the Servo Commander?
I have made allot of progress with my robotic tank, but it will still be better with your new & improved version of Servo Commander.
Please let me know.
Thank you & regards

hi all
Any freeware network simulator tool kit is available for windows and linux ...???/
Regards
Sunny

[Previously: I am not aware of any software that meets your specs. Most network simulators involve some kind of specialized hardware, so you can just put them between both partners and plug them in on either end. For software solutions, you'd probably need a properly configured machine as a bridge, which also has to be fast enough to manipulate the network messages in realtime. That is why there is probably no free solution as well. Yes, you might receive the SW for free, but the specialized box it runs on costs $$$.]
I stand corrected. Randor has provided you with a link, please check it out.
Cheers,
Sebastian

Imagine that you wanted to test how your network software will perform over satellite but the only problem is that you dont have a satellite. Perhaps you wanted to determine how that same software would perform over a dial-up connection. What if your users are complaining that your software crashes everytime network latency exceeds 300ms.

how to send messages to administrator or account holder's mobile through bluetooth or any other means when an unauthorised person tries to access any system login or user account or any sort of login form.

The first bit's relatively easy, for instance send them an email. But

Unless all of those systems are rewritten to provide that kind of information, you cannot do what you want. There is no way to monitor every type of system and every window for what "looks like" a login form.

We have a PC/104 (ISA bus) card we designed in 1999 to interface with an internal I2C bus in our line of PROFILE/Plus test equipment for the paper industry. The software was developed under Borland C and runs under DOS. We are porting the design to Windows XPembedded and need a driver for this card. I have studied about 370 pages of "Developing Drivers with the Windows Driver Foundation" by Penny Orwick and Guy Smith, read the article "Bulding and deploying a basic WDF Kernel Mode Driver" by Bruno van Dooren, and several of the Toby Opferman articles on Driver Development.
I still do not know if I am going in the right direction. There is very little mention of the actual interface with the hardware. I recently found some references to "I/O commands" like "READ_PORT_XXX" and "WRITE_PORT_XXX" where XXX can be UCHAR, ULONG, USHORT, ULONG64. However, most references indicate these are to be used in Windows CE. Do I need something to tell WDF that the interface is an ISA bus and the interface is through I/O addresses?
The board in question uses a passive Philips "bridge" part that simply has registers we get to by decoding I/O addresses on the PC/104 I/O bus. Can I get to these directly in response to a IRP initiated by a user request?
My second concern is "adding the device". Does WDF initiate a callback to the "EvtDeviceAdd" immediately after the WdfDriverCreate? van Dooren stated, "The EvtDeviceAdd function will be called each time the system determines that a new device has been connected". If not, how do I "tell" the system that our passive board is present?

No these functions can also be used for your embedded XP project. You can think of these wrappers as the equivilent of the old DOS _outp, _outpw, _outpd[^] functions. You stated your device driver was implemented in Borland-C so your old code would have probably used outport[^] and outportb[^].
William R. Price wrote: Do I need something to tell WDF that the interface is an ISA bus and the interface is through I/O addresses?
If your PC104 card supports PnP ISA then when embedded XP boots the PnP manager will query the card and allocate the appropriate resources then send your driver a IRP_MN_QUERY_RESOURCE_REQUIREMENTS[^] request and ask your driver for its resource requirements which can be described in the IO_RESOURCE_REQUIREMENTS_LIST[^] struct which allows your driver to modify the resource requirements.
You will essentially need to write a PnP ISA device driver using WDF and create am INF file which contains the resource requirements. You could also write a co-installer and install the driver progmatically rather than use the INF file. More information here:
Device Installation FAQ[^]

If the Plug and Play manager has successfully detected your device the EvtDriverDeviceAdd[^] callback is fired. The PnP manager already knows about the existence of your device at this point. The callback is there for you to initialize any additional resources or interfaces.

Hi Everyone,
I have a windows Application developed with .Net 2005 and C#. It communicates with a device using virtual COM Port. I use Windows XP Home and Prof. It works fine everywhere.
But recently I shipped the software to one of my client. There it creates problem. During its first run the software checks all COM Ports by sending specific command and where it finds proper response it detects that the device is attached to that Port. This is a regular process of the software. But, while checking the COM ports the application gets stuck after sending command to COM Port. And only way to close it is from Task Manager. This happens with 4 to 5 system, the client had tried.
I have also written Log files, there also after sending Command to com port, nothing is logged.
Note : No Anti Virus is installed there; Drivers are installed properly; Device is detected by the system when attached; displayed in device manager
Any suggestion or hint will be greatly appreciated...
Regards,
-SIFAR.

That seems to be a bad idea: COM ports can be busy, allocated, non-existing, or connected to special hardware (modem, infra-red, bluetooth,...).
Try the same "sending some command" using HyperTerminal to see it fail.

Is this a USB device using a virtual COM port? If so, here's what I do to find the COM port it's connected to.
NOTE: I'm not sure what the standard practice is for this, there may be a better way, but this was worked just fine for me so far. If anyone knows of a better, more robust way to do this, I'm open to suggestions.
You can determine which COM port the device is connect to by searching the registry under
HKLM\SYSTEM\CurrentControlSet\Enum\USB\VID_xxxx&PID_xxxx
where xxxx is the hex identifier for the VendorID and ProductID of the device. Inside this key is another subkey for each instance of the device, and then in the Device Parameters key you'll see PortName (I think, can't remember off hand exactly what it is). Anyway, the name of the COM port can be found here. You can iterate through each instance in the registry and attempt to open the .NET SerialPort object. If you successfully open the port, then the device is connected.
So you'll want to look for the key
HKLM\SYSTEM\CurrentControlSet\Enum\USB\VID_xxxx&PID_xxxx\<all subkeys="">\Device Parameters</all>
and read the PortName value from each instance.
foreach(string curPortName in portNames)
{
port.Name = curPortName;
try
{
port.Open();
break;
}
catch(InvalidOperationException ex)
{
}
catch(UnauthorizedAccessException ex){
}
}
You can check the MSDN documentation for how to read info from the Registry in C#.
