problem with echo in teststand

[Noubissi]

Hi,

I have a function writen in C (Labwindows CVI). In this function  i try to send an echo to  another Programm. When i run the function in CVI , it walks without any Problem. But when i try to call the function from Teststand 3.5 , it doesn't walk properly. Teststand marks the step as Passed although  the command were not executed. I don't understand what is wrong. Is it possible that Teststand doesn't allowed the use of "echo" ?? if not, how can i solve the problem ??

here is my code:

sprintf(cmd,"command.com /C echo %s| prog --command1 \"%s\"", ECHOTEXT, SAVE);

LaunchExecutableEx(cmd,LE_SHOWNORMAL, &hdl);

prog is the name of the programm i am sending the echo to.

I hope somebody can have an answer.

Regards,

Noubissi

Hello Robert,

Thanks for your answer, but the solution you proposed don't solve my problem, since i am not calling the programm from Teststand directly  like you did.

 I am using Teststand to call a function written in CVI, and the job of that function is  to call a programm and pass arguments using echo.

This is the function i am  calling from TestStand: 

int TestFunction()

{

char cmd[300]={0};

int hdl;

char * ECHOTEXT= "echotext";

char *SAVE ="C:\\Develop";

sprintf(cmd,"command.com /C echo %s| prog --command1 \"%s\"", ECHOTEXT, SAVE);

LaunchExecutableEx(cmd,LE_SHOWNORMAL, &hdl); 

return(0);

}
