assing [ComputerName] to szLine parameter

[jagjit_82]

hii...
i want to assign or say pass [computerName] to parameter szLine of
predefine function EzBatchAddString (szLine, szRefKey, nOptions).
i want to do it because i want to set the environment variable in batch file to
this value(ComputerName)
But when i set
szline=[ComputerName]
or
szLine=ComputerName
the compiler complaints for an error...

can u plz tell me how can i achieve this.

thanks

I would suggest to first retrieve the value of ComputerName environment variable in a string and then pass it on to another function. Use GetEnvVar function to resolve the environment variable value:

GetEnvVar("ComputerName", sCompName);

Then use sCompName like any other variable in the Ez functions.

hi
when i added this function into my code..upon compilation i encountered 50 errors
this is my code

can u plz tell me where's the error

#include "ifx.h"

export prototype MyFunction(HWND);
STRING szLine, szRefKey;
NUMBER nOptions;
STRING sCompname

function MyFunction(hMSI)
// To Do: Declare local variables.
begin

#define BATCH_FILE "C:\\ISExampl.bat"

// Include Ifx.h for built-in InstallScript function prototypes.

GetEnvVar("ComputerName",sCompname);

// Set the default batch file.
BatchSetFileName (BATCH_FILE);

// Set up parameters for next call to EzBatchAddString.
szLine = "rem This is the first line of the file.";
szRefKey = "";
nOptions = BEFORE|NOSET;

// Add a comment line to the top of the batch file.
if (EzBatchAddString (szLine, szRefKey, nOptions) < 0) then
MessageBox ("First call to EzBatchAddString failed.", SEVERE);
else
MessageBox ("First call to EzBatchAddString successful.", INFORMATION);
endif;

// Set up parameters for next call to EzBatchAddString.
szLine = "TEMP=C:\\EXAPP3";
szRefKey = "PATH";
nOptions = AFTER;

// Add a line after the PATH statement.
if (EzBatchAddString (szLine, szRefKey, nOptions) < 0) then
MessageBox ("Second call to EzBatchAddString failed.", SEVERE);
else
MessageBox ("Second call to EzBatchAddString successful.", INFORMATION);
endif;

// Set up parameters for next call to EzBatchAddString.
szLine = "C:\\EXAPP3\\EXAPP.EXE";
szRefKey = "TEMP";
nOptions = AFTER|NOSET;

// Add a command line after the SET TEMP statement.
if (EzBatchAddString (szLine, szRefKey, nOptions) < 0) then
MessageBox ("Third call to EzBatchAddString failed.", SEVERE);
else
MessageBox ("Third call to EzBatchAddString successful.", INFORMATION);
endif;

// Set up parameters for next call to EzBatchAddString.
szLine = "PATH=C:\\;C:\\Windows";
szRefKey = "PATH";
nOptions = AFTER|NOSET|REPLACE|COMMAND;

// Replace the PATH statement.
if (EzBatchAddString (szLine, szRefKey, nOptions) < 0) then
MessageBox ("Fourth call to EzBatchAddString failed.", SEVERE);
else
MessageBox ("Fourth call to EzBatchAddString successful.", INFORMATION);
endif;

//endprogram


end;

Tough...I can tell but I have to recompile it. Since I am a lazy guy, would you mind copy the errors you are encountering? Please....

[jagjit_82]

these are the errors which i encountered when i jst added these two lines in the code

STRING sCompname
GetEnvVar("ComputerName",sCompname);



following are errors generated only by the addition of these two lines in the code

You'll want to add a semicolon after this line:

STRING sCompname

to make it:

STRING sCompname;
