ExpandMacrosEx
 

I am using the ExpandMacrosEx method in a script running in the GUI. I use the following code:

Application.ExpandMacrosEx(%VAR%, vbldUndefLeave, strResult, False)

Even though I use the vbldUndefLeave as the undefTreatment parameter, the 'Enter Undefined Macro Value' dialog still appears.

I would think that the result should be that the strResult should contain the unexpanded macro if it is not defined.

----------
The above was an attempt to work around the original purpose of this script. I want to write to a file the contents of a variable %VAR% that contains text with special characters such as '%' and '['.

Is there a way to write to a file the literal text without variable expansion? I even tried to replace the '%' with '%%' in the variables. But when attempting the replace the '%' character is still being evaluated as a macro.

Help on either of these issues would be appreciated.

If you have that code in a step field, the first thing it will do (before evaluating the script code) is expand any macros in the string. To prevent it from doing that, use double percent chars (i.e., Application.ExpandMacrosEx("%%VAR%%"...). However, that function is not actually callable from script code since it takes a non-variant in/out parameter.

A run script step with this VBScript code would do it (uses the DOSCMD macro as an example):

vbld_FSO().CreateTextFile("%TEMP%\xyz.txt").Write(vbld_AllMacros()("DOSCMD").Value)
