Hi, I've a script, using WinAPIGdi, checking info on font files for some files, I get the error "C:\DEV\AutoIt3\Include\WinAPIGdi.au3" (2480) : ==> Variable must be of type "Object".: and then the script stops. Is there a way I can either "catch" that error, and let my script continue with the next file or improve something in the WinAPIGdi script? I've searched the forums on error handling, but couldn't immediately find something related tho errors like these which are hardstopping the script P.S. : I'm an AutoIT script newbie..... snippet from WinAPIGdi, line 2480 from the error is this one: $sResult = $tResult.szTTFName ; #FUNCTION# ==================================================================================================================== ; Author ........: funkey ; Modified ......: UEZ, jpm ; =============================================================================================================================== Func _WinAPI_GetFontMemoryResourceInfo($pMemory, $iFlag = 1) Local Const $tagTT_OFFSET_TABLE = "USHORT uMajorVersion;USHORT uMinorVersion;USHORT uNumOfTables;USHORT uSearchRange;USHORT uEntrySelector;USHORT uRangeShift" Local Const $tagTT_TABLE_DIRECTORY = "char szTag[4];ULONG uCheckSum;ULONG uOffset;ULONG uLength" Local Const $tagTT_NAME_TABLE_HEADER = "USHORT uFSelector;USHORT uNRCount;USHORT uStorageOffset" Local Const $tagTT_NAME_RECORD = "USHORT uPlatformID;USHORT uEncodingID;USHORT uLanguageID;USHORT uNameID;USHORT uStringLength;USHORT uStringOffset" Local $tTTOffsetTable = DllStructCreate($tagTT_OFFSET_TABLE, $pMemory) Local $iNumOfTables = _WinAPI_SwapWord(DllStructGetData($tTTOffsetTable, "uNumOfTables")) ;check is this is a true type font and the version is 1.0 If Not (_WinAPI_SwapWord(DllStructGetData($tTTOffsetTable, "uMajorVersion")) = 1 And _WinAPI_SwapWord(DllStructGetData($tTTOffsetTable, "uMinorVersion")) = 0) Then Return SetError(1, 0, "") Local $iTblDirSize = DllStructGetSize(DllStructCreate($tagTT_TABLE_DIRECTORY)) Local $bFound = False, $iOffset, $tTblDir For $i = 0 To $iNumOfTables - 1 $tTblDir = DllStructCreate($tagTT_TABLE_DIRECTORY, $pMemory + DllStructGetSize($tTTOffsetTable) + $i * $iTblDirSize) If StringLeft(DllStructGetData($tTblDir, "szTag"), 4) = "name" Then $bFound = True $iOffset = _WinAPI_SwapDWord(DllStructGetData($tTblDir, "uOffset")) ExitLoop EndIf Next If Not $bFound Then Return SetError(2, 0, "") Local $tNTHeader = DllStructCreate($tagTT_NAME_TABLE_HEADER, $pMemory + $iOffset) Local $iNTHeaderSize = DllStructGetSize($tNTHeader) Local $iNRCount = _WinAPI_SwapWord(DllStructGetData($tNTHeader, "uNRCount")) Local $iStorageOffset = _WinAPI_SwapWord(DllStructGetData($tNTHeader, "uStorageOffset")) Local $iTTRecordSize = DllStructGetSize(DllStructCreate($tagTT_NAME_RECORD)) Local $tResult, $sResult, $iStringLength, $iStringOffset, $iEncodingID, $tTTRecord For $i = 0 To $iNRCount - 1 $tTTRecord = DllStructCreate($tagTT_NAME_RECORD, $pMemory + $iOffset + $iNTHeaderSize + $i * $iTTRecordSize) If _WinAPI_SwapWord($tTTRecord.uNameID) = $iFlag Then ;1 says that this is font name. 0 for example determines copyright info $iStringLength = _WinAPI_SwapWord(DllStructGetData($tTTRecord, "uStringLength")) $iStringOffset = _WinAPI_SwapWord(DllStructGetData($tTTRecord, "uStringOffset")) $iEncodingID = _WinAPI_SwapWord(DllStructGetData($tTTRecord, "uEncodingID")) Local $sWchar = "char" If $iEncodingID = 1 Then $sWchar = "word" $iStringLength = $iStringLength / 2 EndIf $tResult = DllStructCreate($sWchar & " szTTFName[" & $iStringLength & "]", $pMemory + $iOffset + $iStringOffset + $iStorageOffset) If $iEncodingID = 1 Then $sResult = "" For $j = 1 To $iStringLength $sResult &= ChrW(_WinAPI_SwapWord(DllStructGetData($tResult, 1, $j))) Next Else $sResult = $tResult.szTTFName EndIf If StringLen($sResult) > 0 Then ExitLoop EndIf Next Return $sResult EndFunc ;==>_WinAPI_GetFontMemoryResourceInfo the function in my script: Func FontGetInfoFromFile($sFile, $n, $sElement) Local $s = _WinAPI_GetFontResourceInfo($sFile, Default, $n) If Not @error And $s Then ConsoleWrite($sElement & " = " & $s & @CRLF) If @error Then ConsoleWrite ("ERROR!!!")
