||
| 31 | |||
| 1 | daniel-mar | 32 | Structure of a ViaThinkSoft AutoSFX Archive |
| 33 | ------------------------------------------- |
||
| 34 | |||
| 35 | 1. Extractor [UPX'ed] |
||
| 36 | includes DelZip190.dll (B4) as Resource |
||
| 37 | 2. ZIP (Offset adjusted) |
||
| 38 | File comment includes "ViaThinkSoft AutoSFX Archive" |
||
| 39 | 3. Optional: Authenticode Certificate |
||
| 40 | |||
| 41 | Process |
||
| 42 | ------- |
||
| 43 | |||
| 44 | 1. Extract DelZip DLL into TempDir |
||
| 45 | 2. Extract contents directly |
||
| 46 | 3. Open the extracted data and/or execute special AutoRun.inf (see below) |
||
| 47 | 4. Delete the DLL from TempDir |
||
| 48 | |||
| 49 | Behavior |
||
| 50 | -------- |
||
| 51 | |||
| 52 | ZIP has 1 file |
||
| 5 | daniel-mar | 53 | => Extract DIRECTLY in the specified directory |
| 1 | daniel-mar | 54 | Is it a directory? |
| 55 | => Open the new directory in Windows Explorer |
||
| 56 | is it a file? |
||
| 57 | => Open Windows Explorer and select the new file. |
||
| 58 | ZIP has 2+ files |
||
| 59 | => Create a directory with the name of the SFX and extract into it |
||
| 60 | => Open the new created directory in Windows Explorer |
||
| 61 | |||
| 62 | Semantic archive comment |
||
| 63 | ------------------------ |
||
| 64 | |||
| 65 | The extractor looks into the file comment to determinate the behavior |
||
| 66 | while unzipping. YOU can influence the behavior when creating your |
||
| 67 | ZIP files. |
||
| 68 | |||
| 69 | Following switches are possible: |
||
| 70 | |||
| 71 | C_ASFX_CB_OVR = 'AutoSFX Conflict Behavior: Overwrite all'; |
||
| 72 | C_ASFX_CB_NEW = 'AutoSFX Conflict Behavior: Overwrite older'; |
||
| 73 | C_ASFX_CB_ASK = 'AutoSFX Conflict Behavior: Ask'; |
||
| 5 | daniel-mar | 74 | C_ASFX_CB_AVO = 'AutoSFX Conflict Behavior: Avoid'; (default) |
| 1 | daniel-mar | 75 | |
| 76 | C_ASFX_CP_BEF = 'AutoSFX Comment Presentation: Before extracting'; |
||
| 77 | C_ASFX_CP_AFT = 'AutoSFX Comment Presentation: After extracting'; |
||
| 5 | daniel-mar | 78 | C_ASFX_CP_NON = 'AutoSFX Comment Presentation: None'; (default) |
| 1 | daniel-mar | 79 | |
| 5 | daniel-mar | 80 | C_ASFX_FC_THS = 'AutoSFX Extraction Target: Extract here'; (default) |
| 1 | daniel-mar | 81 | C_ASFX_FC_DSK = 'AutoSFX Extraction Target: Extract to Desktop'; |
| 82 | C_ASFX_FC_ASK = 'AutoSFX Extraction Target: Choose directory'; |
||
| 83 | |||
| 5 | daniel-mar | 84 | Note: If you are running the SFX from a CD-Rom, a write-protected |
| 85 | directory or a flobby (doesn't matter if it is write-protected!), |
||
| 86 | the extraction "Here" will be ignored and converted into "Desktop". |
||
| 87 | |||
| 88 | Note: "Avoid" means that an alternative file/foldername will be |
||
| 89 | determinated. |
||
| 90 | |||
| 1 | daniel-mar | 91 | Special AutoRun.inf |
| 92 | ------------------- |
||
| 93 | |||
| 94 | [AutoSFX] |
||
| 95 | Operation=open ; Part of ShellExecute. Usually 'open' or 'runass' (e.g. for admin privilegies) |
||
| 96 | FileName=AutoRun.exe ; The filename to be executed |
||
| 97 | Parameters= ; Optional parameters |
||
| 98 | Directory= ; Optional Working directory |
||
| 99 | ShowCmd= ; (See MSDN Reference) Usually WS_NORMAL or WS_HIDE |
||
