LeCroy Waverunner 104 xi store trace / destination file setup

Question

Hi everybody,
My question might be really simple, but it took me already days without real success...
I'm currently programming a LeCroy waverunner 104 Xi on CVI 8.5 via LAN. I'm trying to save a trace from a channel C 1...4 or internal memory M 1...4 to a previously specified file on the scope in *.xls or *.txt format. This already works with the STORE command on HDD ('STO C2, FILE'), but only on in a file I specified via keyboard on the scope / the save dialog. The STORE_SETUP command enables me to access all parameters (mode, data type...) of the "save waveform", except the save directory and the filename.
How can I set this up / which command must be used to specify the destination file. I'm missing something like the Hardcopy_Setup command, where I can just enter the target path and the name...
I'm really grateful for every answer!

Hi Peter,
thank you for your welcome and the answer!
You're right, I was a bit short with information, sorry. I installed the LeCroy LAB_WM827 VICP Passport for the connection. My communication runs on a LAN connection via this. The commands I am using are from the LeCroy Remote Control Manual Feb. 2005 (seems to be the actual / newest release). A simple example for connecting to the device is in the following:
#include <ansi_c.h>
#include <userint.h>
#include <visa.h>
#define MAX_CNT 200
ViSession defaultRM, instr; /* Communication channels */
ViStatus status; /* For checking errors */
ViUInt32 retCount; /* Return count from string I/O */
ViChar IOStringBuffer[MAX_CNT]; /* Buffer for string I/O */
// Connection
// Open LAN
int ConnectDevice (char IP_Adress[])
char IP_Buf[30];// Adress string
status = viOpenDefaultRM(&defaultRM);
if (status < VI_SUCCESS) {
return -1;
strcpy(IP_Buf, "VICP::");
strcat(IP_Buf, IP_Adress);
strcat(IP_Buf, "::INSTR\n");
status = viOpen(defaultRM, IP_Buf, VI_NULL, VI_NULL,&instr); // Open LAN
status = viSetAttribute(instr, VI_ATTR_TMO_VALUE, 5000); // Timeout 5s   // command: 'VICP::<IP_Adress::INSTR>'  return 0;
In the same way I want to save my data to the HDD of the scope. First I set up the store mode:
char storeSetup[50]={"STST C2, HDD, FILL, ASCII"};
//command: "STST <channel>, <destination>, <mode>, <type>"
status = viWrite(instr, storeSetup, strlen(storeSetup), &retCount);
if(status < VI_SUCCESS)
return -1;
Then I execute the the store command:
char store[30] = {"STO C2, FILE"};
//command: "STO <trace>, <destination>"
status = viWrite(instr, store, strlen(store), &retCount); if(status < VI_SUCCESS) return -1;  
Up to here, everything works. But my specific problem is that I found no command to specify the target file (like C:\Dateien\Messwert1.txt), where my data should be saved. Everything has to be set at the display of the scope and can't be specified in the software (at least not by me).Now I am looking for the command / code, how to implement the target file setup into my code, so I can ask the user for an input via the CVI frontend and send this string to the scope via "viWrite(...);".
I hope I was able to explain my problem.
Thanks in advance for any help!
