HMBatch as server

Altair Forum User

Hi all,

 

I wanted to launch hypermesh as a server and my client will send various requests to the server.

 

***********************************************************************************************************************************

SERVER CODE : HM_Server.tcl

 

set LogFile [open C:/temp/tcl_out.txt w]

 

proc Server {channel clientaddr clientport} {

global LogFile

puts $LogFile 'Hello'

}

 

set chanID [socket -server Server 30000]

puts $chanID

 

***********************************************************************************************************************************

 

I'm launching the hmopengl.exe using ShellExecuteEx method.

 

***********************************************************************************************************************************

CLIENT CODE

 

//Format the command line parameter to be passed for HM in batch mode

TCHAR* cmdLineParam = TEXT('-tcl C:/HM/Tcl_Scripts/HM_Server.tcl');

 

//Execute the hypermesh in batch mode and wait for it to complete

HINSTANCE hInst = 0;

SHELLEXECUTEINFO ShExecInfo = {0};

ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);

ShExecInfo.fMask = SEE_MASK_DEFAULT;

ShExecInfo.hwnd = GetSafeHwnd();

ShExecInfo.lpVerb = TEXT('Open');

ShExecInfo.lpFile = TEXT('C:\\Program Files\\Altair\\12.0\\hm\\bin\\win64\\hmopengl.exe');        

ShExecInfo.lpParameters = cmdLineParam;   

ShExecInfo.lpDirectory = NULL;

ShExecInfo.nShow = SW_SHOWNORMAL;

ShExecInfo.hInstApp = hInst; 

ShellExecuteEx(&ShExecInfo);

 

 

***********************************************************************************************************************************

The above code is working fine with hmopengl.exe

where as it is not working with hmbatch.exe [ ShExecInfo.lpFile = TEXT('C:\\Program Files\\Altair\\12.0\\hm\\bin\\win64\\hmbatch.exe') ];

I could not find the issue...

Hi

I do not ever use hmbatch. but i guess perhaps it use tcl shell (not wish app like in hm), you may need vwait to enter event loop

anyway, I see your client invoked server code, why?

 

client should access server via socket $serverIP 30000

 

and if you already test on hm before, the port may not be used again by hmbatch server. Using free port is recommended

and don't forget flushing channel

 

If you are communicating between different hypermesh session on one pc, you can use dde facility, it is more simple than socket
