[problem to read the Altitude of aircraft in 0x570]

yes ,used the _int64 can get the full 64-bit value.thanks.

[problem to read the Altitude of aircraft in 0x570]

I found the reason! I use FSInterrogate to read the 0x570 ,the value is 566473064448 HEX:83E46D0000

hex viewer

offest

0001 0203 0405 0607

0x570 0000 6DE4 8300 0000

use the fsuipc read the frist part 0x570 ,value is E46D0000 ,read the second part 0x574 ,value is 83。

I don't know how to connect the two part into the rally value.

[problem to read the Altitude of aircraft in 0x570]

Hi,peter.

I have a problem while convert the Altitude of aircraft to feet. Example ,the Altitude of aircraft is 440 feet ,i read the 0x570 ,result is 3833856000, 3833856000*3.28084/(65536*65536)=2.92. read the gps Altitude (0x6020) also can't convert to a correct value. can you help me? thanks.

[How to use offset 3200(send keystrokes to FS)?]

Dear Pete:

I'm doing a small software trying to use a camera to control view direction of FS2004. So I need to send view command to fs through FSUIPC。But I'm confusd when I find the description in the Offset table as below :(

3200

12

These locations operate the FSUIPC facility to send keystrokes to FS. For this to operate correctly the PC must be using Windows 98, ME or 2000. The facilities used just do not exist in Windows 95 nor NT.

3200 message (WM_KEYDOWN or WM_KEYUP)

3204 wParam for the message

3208 lParam for the message

All 12 bytes must be written in one IPC write. (This feature is used in WideClient version 3.998 and later, when the [user] parameter "SendKeyPresses=Yes" is included in its .ini file, to relay all non-system (i.e. no Alt key) key presses it receives to the WideServer host).

How to use offset 3200? Need I registe Widefs first? What are the messages? wParam ,lParam?

Thanks !

:D

a fs fan.

[Read Heading value 0x580 have problem]

hi,peter

when I read the Heading 0x580,Ican't get the correct value.can you help me .FS2004 show heading is 340 .

DWORD head;

if (!FSUIPC_Read(0x580, 4, &head, &dwResult)||!FSUIPC_Process())

{}

int heading= head*360/(65536*65536);

Edit12->Text =heading;

i track into .found the value of head is 3730953 .so 3730953*360/(65536*65536)<0,program error.

[why use FSUIPC_Write can't modify the frequency]

thanks, modify sucessful.I am very happy now ,thanks again :D

[why use FSUIPC_Write can't modify the frequency]

thanks peter,I know the reason,but I still don't know how to translate the noamal Frequency into hex,For EXAMPLE:115.65=0x ?

[why use FSUIPC_Write can't modify the frequency]

I want to modify the nav1 stby freq.so I writed the value to 0X311E,but after execute the program,I found the nav1 stby freq didn't changed at all.

void __fastcall TForm1::Timer1Timer(TObject *Sender)

{

DWORD dwResult;

char String[32], chTime[3];

BOOL fTimeOk = TRUE;

unsigned long pdwResult;

if (!dwClosed) {

if (!FSUIPC_Read(0x238, 3, chTime, &dwResult) ||

!FSUIPC_Process(&dwResult))

fTimeOk = FALSE;

char t[32]="1234";

FSUIPC_Write(0x311e, 2, &t, &pdwResult); //modify nav1 freq

// Now display all the knowledge we've accrued:

if (fTimeOk) {

Label2->Caption = "OK";

sprintf(String, "%02d:%02d:%02d", chTime[0], chTime[1], chTime[2]);

Label8->Caption = String;

}

else {

Label2->Caption = "Failed";

}

}

}

thanks Pete, I Will try another.

[help with the fsuipc sample (Failed to open link to FSUIPC)]

a new found! when i copy the HELLO.EXE program to the windows 2000 system. the HELLO.EXE running ! the program can show the fsuipc message. maybe the problem is in the operation system. why the WINDOWS xp CAN'T RUN ?

[help with the fsuipc sample (Failed to open link to FSUIPC)]

thank you for your reply ,my system is windows xp. and you say"So, to connect, you use the code or library supplied." ,which library i should add to the program? now I used the BCB. the code is the sdk file's sample and I didn't modify anything.I don't know what made this error.

help with the fsuipc sample

I want to write some application to interface to fs2004,when I run the FSUIPC SDK 28th Release sample(\UIPC_SDK_BCB5) .the pragram running

result show "Incorrect version of FSUIPC, or not FSUIPC", "Failed to open link to FSUIPC". I CHECK the Code ,found this program need to find

the "UIPCMAIN ",

// Connect via FSUIPC, which is known to be FSUIPC's own

// and isn't subject to user modificiation

m_hWnd = FindWindowEx(NULL, NULL, "UIPCMAIN", NULL);

if (!m_hWnd)

{ // If there's no UIPCMAIN, we may be using WideClient

// which only simulates FS98

m_hWnd = FindWindowEx(NULL, NULL, "FS98MAIN", NULL);

fWideFS = TRUE;

if (!m_hWnd)

{ *pdwResult = FSUIPC_ERR_NOFS;

return FALSE;

}

}

My question is,what is the UIPCMAIN,what should I do to connect to fsuipc.

I had install fsuipc3.8 into fs2004 and registered sucessful. log file as follow:
