You might look at your data model and see if you need to specify any additional indexes that Access would otherwise create. I believe this is the variable TCP receive window size. XP, R1 and had a fixed TCP receive window size, which effectively limited their default throughput to around 5Mbps. I'll delve further into it to check. Where relationships exist between tables, they reside within the same file. Just to re-iterate, the application performance seems fine, this is only on entering design view.
Do I understand you correctly - you are suggesting that Access may be creating an index each time I enter design view on a subform that doesn't have a defined relationship?
And whad'ya know?!! I don't know why I believed that R2 supported this feature but it doesn't. Either way, until I upgrade to Windows server I won't be enabling autotuning on my Vista client. Here's a good overview of the background to this setting. Sage Thanks for your help, lads. Vista uses auto-tune by default, Windows R2 cannot auto-tune.
So in my case it was when the client auto-tunes but the server does not. Thanks for all the hard work you did in figuring out this problem.
If you would like to email me your name, first name only is fine, or whatever you feel comfortable with I'd be happy to add that to the web page. I have a user who has XP with Access She has a query that accesses an Oracle 10g database and returns about 7 rows. Time to execute is less than 1 second. Same problem when she tries to save it. Any ideas? I have no idea. Let me run this one past my fellow MVPs and Microsoft.
No, really I am kidding. One suggestion was to ensure that Name AutoCorrect is turned off. Can you repro that situation? MS would love to have that situation repro'd so they can get their team to take a look at it.

Hi I tried a search but found nought. Allen Browne. I don't have a solution for you, but let's explore this further. The Heap Manager implements additional features such as integrity checking in order to improve robustness and defend against buffer overflow security exploits, although this comes at the price of breaking backward compatibility with some legacy applications.
A Kernel Transaction Manager has been implemented that enables applications to work with the file system and Registry using atomic transaction operations. Improved security was a primary design goal for Vista. Microsoft's Trustworthy Computing initiative, which aims to improve public trust in its products, has had a direct effect on its development.
This effort has resulted in a number of new security and safety features. UAC is a security technology that makes it possible for users to use their computer with fewer privileges by default, with a view to stopping malware from making unauthorized changes to the system. This was often difficult in previous versions of Windows, as the previous "limited" user accounts proved too restrictive and incompatible with a large proportion of application software, and even prevented some basic operations such as looking at the calendar from the notification tray.
Regular use of the computer such as running programs, printing, or surfing the Internet does not trigger UAC prompts. User Account Control asks for credentials in a Secure Desktop mode, in which the entire screen is dimmed, and only the authorization window is active and highlighted. The intent is to stop a malicious program misleading the user by interfering with the authorization window, and to hint to the user the importance of the prompt.
Symantec used over 2, active malware samples, consisting of backdoors, keyloggers , rootkits, mass mailers, trojan horses, spyware, adware, and various other samples. Each was executed on a default Windows Vista installation within a standard user account. UAC effectively blocked over 50 percent of each threat, excluding rootkits.
Internet Explorer 7 's new security and safety features include a phishing filter, IDN with anti-spoofing capabilities, and integration with system-wide parental controls. For added security, ActiveX controls are disabled by default. Also, Internet Explorer operates in a protected mode, which operates with lower permissions than the user and runs in isolation from other applications in the operating system, preventing it from accessing or modifying anything besides the Temporary Internet Files directory.
Microsoft's anti-spyware product, Windows Defender , has been incorporated into Windows, providing protection against malware and other threats. Changes to various system configuration settings such as new auto-starting applications are blocked unless the user gives consent. Whereas prior releases of Windows supported per-file encryption using Encrypting File System , the Enterprise and Ultimate editions of Vista include BitLocker Drive Encryption which can protect entire volumes, notably the operating system volume.
However, BitLocker requires approximately a 1. In normal circumstances, the only time this partition is accessed is when the computer is booting, or when there is a Windows update that changes files in this area which is a legitimate reason to access this section of the drive.
The area can be a potential security issue, because a hexadecimal editor such as dskprobe. However, as with other full disk encryption technologies, BitLocker is vulnerable to a cold boot attack, especially where TPM is used as a key protector without a boot PIN being required too. A variety of other privilege-restriction techniques are also built into Vista. An example is the concept of "integrity levels" in user processes, whereby a process with a lower integrity level cannot interact with processes of a higher integrity level and cannot perform DLL—injection to a processes of a higher integrity level.
The security restrictions of Windows services are more fine-grained, so that services especially those listening on the network have no ability to interact with parts of the operating system they do not need to. Obfuscation techniques such as address space layout randomization are used to increase the amount of effort required of malware before successful infiltration of a system.
Code Integrity verifies that system binaries have not been tampered with by malicious code. As part of the redesign of the network stack, Windows Firewall has been upgraded, with new support for filtering both incoming and outgoing traffic. Advanced packet filter rules can be created which can grant or deny communications to specific services. The bit versions of Vista require that all device drivers be digitally signed, so that the creator of the driver can be identified.
While much of the focus of Vista's new capabilities has highlighted the new user-interface, security technologies, and improvements to the core operating system, Microsoft also adding new deployment and maintenance features:. Windows Vista includes a large number of new application programming interfaces. Chief among them is the inclusion of version 3. Version 3. These technologies are also available for Windows XP and Windows Server to facilitate their introduction to and usage by developers and end users.
There are also significant new development APIs in the core of the operating system, notably the completely re-architected audio, networking, print, and video interfaces, major changes to the security infrastructure, improvements to the deployment and installation of applications "ClickOnce" and Windows Installer 4. There are some issues for software developers using some of the graphics APIs in Vista.
Games or programs which are built solely on the Windows Vista-exclusive version of DirectX , version 10, cannot work on prior versions of Windows, as DirectX 10 is not available for previous Windows versions. Also, games which require the features of D3D9Ex, the updated implementation of DirectX 9 in Windows Vista are also incompatible with previous Windows versions.
However, hardware overlay is not supported, because it is considered as an obsolete feature in Vista. The "Hardware profiles" startup feature has also been removed, along with support for older motherboard technologies like the EISA bus, APM and Game port support though on the bit version game port support can be enabled by applying an older driver. Windows Vista does not include the " Luna " visual theme, created in for Windows XP, or most of the classic color schemes which have been part of Windows since the Windows 3.
Also the caption buttons are changed. Only Windows Classic can still be found in that operating system. Windows Vista ships in six different editions. These are roughly divided into two target markets, consumer and business, with editions varying to cater for specific sub-markets.
For consumers, there are four editions, with three available for economically more developed countries. Windows Vista Home Basic is intended for budget users and is available only in emerging markets. Windows Vista Home Premium covers the majority of the consumer market, and contains applications for creating and using multimedia.
The home editions cannot join a Windows Server domain. For businesses, there are three editions. Windows Vista Business is specifically designed for small and medium enterprises small and medium-sized businesses, is only available to customers participating in Microsoft's Microsoft Software Assurance Software Assurance program.
Windows Vista Ultimate contains the complete feature-set of both the Home and Business combination of both Home Premium and Enterprise editions, as well as a set of Windows Ultimate Extras , and is aimed at enthusiasts. All editions except Windows Vista Starter support both bit x86 and bit x64 processor architectures. Similar sanctions exist in South Korea.
A Vista Capable or equivalent PC is capable of running all editions of Windows Vista although some of the special features and high-end graphics options may require additional or more advanced hardware. Windows Vista's Basic and Classic interfaces work with virtually any graphics hardware that supports Windows XP or ; accordingly, most discussion around Vista's graphics requirements centers on those for the Windows Aero interface.
Microsoft offers a tool called the Windows Vista Upgrade Advisor to assist Windows XP and Vista users in determining what versions of Windows their machine is capable of running. Although the installation media included in retail packages is a bit DVD, customers needing a CD-ROM or customers who wish for a bit install media are able to acquire this media through the Windows Vista Alternate Media program. The Ultimate edition includes both bit and bit media. The digitally downloaded version of Ultimate includes only one version, either bit or bit, from Windows Marketplace.
Maximum limits on physical memory RAM that Windows Vista can address vary depending on the both the Windows version and between bit and bit versions. The following table specifies the maximum physical memory limits supported:. The total maximum number of logical processors of a PC that Windows Vista supports is: 32 for bit; 64 for bit. Microsoft occasionally releases service packs for its Windows operating systems to fix bugs and add new features.
The initial deployment of the service pack caused a number of machines to continually reboot, rendering the machines unusable. This caused Microsoft to temporarily suspend automatic deployment of the service pack until the problem was resolved. The synchronized release date of the two operating systems reflected the merging of the workstation and server kernels back into a single code base for the first time since Windows Initially, the service pack only supported 5 languages — English, French, Spanish, German and Japanese.
Support for the remaining 31 languages was released on April 14, These examples help demonstrate variations created based on the shape and position of the object itself. The shadow sometimes needs to be feathered or shortened to keep it from being cropped by the icon box size.
Although there is no specific color palette for standard icons, remember that they need to work well together in many contexts and themes. Prefer the standard set of colors; don't re-color standard icons, such as warning icons, because this disrupts users' ability to interpret meaning.
For more guidelines, see Color. Icon files require 8-bit and 4-bit palette versions as well, to support the default setting in a remote desktop.
These files can be created through a batch process, but they should be reviewed, as some will require retouching for better readability. Only a bit copy of the x pixel image should be included, and only the x pixel image should be compressed to keep the file size down.
Several icon tools offer compression for Windows Vista. The following tables show examples of scaling ratios applied to two common icon sizes. Note that not all of these sizes must be included in the.
The code will scale larger ones down. As an icon gets smaller, transparency and some special details found in larger sizes should be sacrificed in order to simplify and get the point across. At 16x16, the icon for the portable audio device could easily be mistaken for a cell phone so the ear piece is a key visual detail to show. All sizes need relevant level of detail; the smaller the icon the more you need to exaggerate the defining details. Follow these steps to create a single. For Windows Vista, use thumbnails for files holding content that is visually distinct at small scale, such that users can directly recognize the file they are looking for.
Use the Windows Thumbnailing application programming interface for this. Application icon overlays not shown here on thumbnails help association with the application for the file type, in addition to showing the file's preview. Note: For files without visually distinct content, don't use thumbnails.
