almost everything
the order of instructions
not waiting for results

and let's look at the firstScan params
Code:

 firstScan(scanoption, vartype, roundingtype, input1, input2 ,startAddress ,stopAddress ,protectionflags ,alignmenttype ,"alignmentparam" ,isHexadecimalInput ,isNotABinaryString, isunicodescan, iscasesensitive);
    Does an initial scan.
    memscan: The MemScan object created with createMemScan
    scanOption: Defines what type of scan is done. Valid values for firstscan are:
      soUnknownValue: Unknown initial value scan
      soExactValue: Exact Value scan
      soValueBetween: Value between scan
      soBiggerThan: Bigger than ... scan
      soSmallerThan: smaller than ... scan

    vartype: Defines the variable type. Valid variable types are:
      vtByte
      vtWord  2 bytes
      vtDword 4 bytes
      vtQword 8 bytes
      vtSingle float
      vtDouble
      vtString
      vtByteArray
      vtGrouped
      vtBinary
      vtAll

    roundingtype: Defined the way scans for exact value floating points are handled
      rtRounded : Normal rounded scans. If exact value = "3" then it includes 3.0 to 3.49999999. If exact value is "3.0" it includes 3.00 to 3.0499999999
      rtTruncated: Truncated algorithm. If exact value = "3" then it includes 3.0 to 3.99999999. If exact value is "3.0" it includes 3.00 to 3.099999999
      rtExtremerounded: Rounded Extreme. If exact value = "3" then it includes 2.0000001 to 3.99999999. If exact value is "3.0" it includes 2.900000001 to 3.099999999

    input1: If required by the scanoption this is a string of the given variable type
    input2: If requires by the scanoption this is the secondary input

    startAddress : The start address to scan from. You want to set this to 0
    stopAddress  : The address the scan should stop at. (You want to set this to 0xffffffffffffffff)

    protectionflags : See aobscan about protectionflags
    alignmenttype : Scan alignment type. Valid options are:
      fsmNotAligned : No alignment check
      fsmAligned    : The address must be dividable by the value in alignmentparam
      fsmLastDigits : The last digits of the address must end with the digits provided by alignmentparam

    alignmentparam : String that holds the alignment parameter.

    isHexadecimalInput: When true this will handle the input field as a hexadecimal string else decimal
    isNotABinaryString: When true and the varType is vtBinary this will handle the input field as a decimal instead of a binary string
    isunicodescan: When true and the vartype is vtString this will do a unicode (utf16) string scan else normal utf8 string
    iscasesensitive : When true and the vartype is vtString this check if the case matches


yours:
Code:

scan.firstScan(soValueBetween, vtSingle, rtRounded, "TextOne", 0, 0xffffffffffffffff, "+w", fsmAligned, "4", false, false, false, false)

so
Code:

scanoption=soValueBetween
vartype=vtSingle
roundingtype=rtRounded
input1="TextOne"
input2=0
startAddress=0xffffffffffffffff
stopAddress="+w"
protectionflags=fsmAligned
alignmenttype="4"
alignmentparam=false
isHexadecimalInput=false
isNotABinaryString=false
isunicodescan=false
iscasesensitive=nil


So, first of, the parameter type is wrong, I think you may want to use vtString

Secondly, for text you can only use soExactValue (

Third, you are missing the input2 parameter (I've seen this mistake before in another post. Tip: Don't copy paste code from people asking questions in the forum, they are often wrong)

Fourth, are you sure your string is aligned on a 4 byte boundary ?
