GSM Survey

2010-03-14T11:15:00.000-07:00

Hi there

Ummm..., after some time, traveling far away from home. The climate changes, people changes and many things including Mobile Base Stations.

I, Was thinking, well... U know.., the idea is to build a survey module with all the facts I can gather for a given BT i.e. Signal Strength, BS ID, Frequency, etc...

Ok.. the blog is open for your comments.

And I will update my findings. Today (Now in fact) I gonna start writing the Win CE app.

Warm Booting Windows Mobile 6.0

Hi...

I was playing around my new HTC Kaiser and ummm... some times feel if there is a way to reboot dis and refresh the system, specially, after installing a new program.

Find below what I found on the net... I assume you have configured your ActiveSync correctly and know basics of VC++

Ok here it is

Include this in the header of your CPP code

#include
#define IOCTL_HAL_REBOOT CTL_CODE(FILE_DEVICE_HAL, 15, METHOD_BUFFERED,FILE_ANY_ACCESS)

extern "C" __declspec(dllimport) BOOL KernelIoControl(
DWORD dwIoControlCode,
LPVOID lpInBuf,
DWORD nInBufSize,
LPVOID lpOutBuf,
DWORD nOutBufSize,
LPDWORD lpBytesReturned);

and here is the function

KernelIoControl(IOCTL_HAL_REBOOT, NULL, 0, NULL, 0, NULL);

Have fun..
:)

Kicking out the Printer Driven CashDrawer

2010-02-13T13:30:00.000-08:00

Got panic? ummm its nt that kick... I basically wanted to explain how to send the Direct I/O commands to open the Printer Driven CashDrawer connected to a POS Printer.

Prity simple...

will just paste the code snippet grabbed from my VB (VB6) Code

Private Sub CmdOpenDevice_Click()

OPOSPOSPrinter1.Open("TM-T88IVE") 'Open the PosPrinter
OPOSPOSPrinter1.ClaimDevice(10000) 'Waiting for 10 seconds to get the ctrl
OPOSPOSPrinter1.DeviceEnabled = True

OPOSPOSPrinter1.PrintNormal(2&, Chr(l27) + Chr(112) + Chr(0) + Chr(50) + Chr(250)) 'Key code for the OpenDrawer is 127, 112, 0, 50, 250

End Sub

This will just kick it out

or else, ummm u may use the CashDrawer Service Object

like this

Private Sub OpenDrawer()
OPOSCashDrawer1.Open(StandardE) 'The Name of the device is StandardE
OPOSCashDrawer1.ClaimDevice(10000)

OPOSCashDrawer1.DeviceEnabled = True

OPOSCashDrawer1.OpenDrawer

OPOSCashDrawer1.WaitForDrawerClose(100, 4500, 100, 100)

End Sub

Happy Cording

Changing the MAC address of the NIC

2010-02-11T12:46:00.000-08:00

Recently I wanted to change the MAC id of the NIC, and was searching in the net to find a solution for how to do this from a computer program (By not manually changing the Windows Registry). So I gonna share what I have found from my search.

Please reply to this post with ur findings.
