The Outlook signatures are stored in the %APPDATA%\Microsoft\Signatures\ folder in text, RTF and HTML formats.
In case of multiple signatures, the default can be found through Word automation. Tested in Outlook 2003 and later.
Uninstalling VFP 9.0 does not remove VFP settings stored in the registry or any files that have been added to installation after the fact.
To completely uninstall VFP 9.0
- Launch VFP and note directories returned by HOME() and HOME(7) functions
- Uninstall VFP
- Delete directories from step 1
- delete registry key HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\9.0
Keep in mind that it will delete all previous VFP settings. You may want to make backup before doing that if you want to restore settings later.
VFP stores in an EXE/DLL information about what runtime DLL is required to run it.
|This is sample code. Add error handling and adjust to your requirements as necessary.|
? VfpVersionFromExeOrDll("C:\Program Files\My Company\MyVfpApplication.exe") ? VfpVersionFromExeOrDll("X:\Somefolder\MyVfpDll.dll")
The VFP low level file functions (LLFF) can be used to open a table as a file and read/write its header. The Table Header Record Structure is documented in VFP help under Table File Structure.
Note 1 Removing Structural CDX flag will effectively disassociate CDX file from the table but not delete the CDX file.
Note 2 Removing Memo flag will allow to open a table and access all fields excluding memo fields. Attempt to access the memo fields will generate an error.
Detailed info on Acrobat automation can be found in Interapplication Communication API Reference from Acrobat 8.1 SDK or Acrobat 9.0 SDK at http://www.adobe.com/devnet/acrobat/?navID=downloads. Free registration may be required.
MS security bulletin Vulnerabilities in GDI+ Could Allow Remote Code Execution (957488) lists MS products affected including VFP 8.0 and VFP 9.0. It supersedes MS security bulletin MS08-052 - Vulnerabilities in GDI+ Could Allow Remote Code Execution (954593). I blogged about it at GDI+ security updates for VFP 8.0 and VFP 9.0
The VFP OLE DB Provider allows other programming languages and applications to access Visual FoxPro databases and tables.
The VFP OLE DB Provider is 32-bit dll (VfpOleDB.dll) and cannot be used by 64-bit applications.
VFP OLE DB provider can be downloaded from here. It's the same version as the one included with Visual FoxPro 9.0 SP2.
On 64-bit Windows the 32-bit Windows-based applications run under WOW64 x86 emulator. WOW64 isolates 32-bit applications from 64-bit applications, which includes preventing file and registry collisions. Console, GUI, and service applications are supported. However, 32-bit processes cannot load 64-bit DLLs, and 64-bit processes cannot load 32-bit DLLs.
