Warnings When Downloading DLL Files

When you’re faced with a difficult problem with an application, it’s easy to become caught up in the rush to fix it and lose one’s sense of good judgement. In today’s technology age, viruses are so common that, even with anti-virus software, the odds of a given computer being infected at some point are 1 in 9 as opposed to 1 in 1000 a decade ago. As such precautions should be taken when downloading dll files to fix programs especially considering the privileged environment in which they run. They can do a lot of damage. When you access a site that offers dll files for download be careful.

1) Look at the site and judge for yourself if it looks well-put-together.

2) Scan dll files downloaded IMMEDIATELY before unpacking them.

3) Scan the dll file itself again to be on the safe side.

Even then, a dll file may be corrupt but the odds of malware infection are greatly reduced.

What Are DLL Files For?

DLL files are behind a large percentage of software errors and crashes yet few know what the abbreviation DLL means let alone what or why they are. DLL stands for “Dynamic Link Library” and a dll file is a set of miniature programs or files, usually used by multiple applications that reside in the system folder or the folder from which the application is executed.

Though not a rule, dll files are normally associated with simplifying low-level tasks for applications. For example, d3d8.dll file is Microsoft’s way of simplifying the extremely difficult task of rendering magnificent 3d graphics by providing the generic functions necessary to do so in a simple package.

Another purpose behind them is to save storage space. Certain functions, such as a print function call, are used by multiple programs and for each of these to natively implement the function would be a waste of valuable hard disk space. A dll file provides the function to all the applications that need it without them needing to have the code built-in, thus increasing their size.

On the software development side it makes developing programs much easier with ready-made functions provided by dll files.

In relatively simple words, a dll file is a group of non-independent programs that provide necessary assistance to larger ones.

What To Do If DLL Errors Disable Your System

If dll file errors cause your computer to become unbootable, the standard procedure is to reboot the machine in Safe Mode. During the boot process your computer will likely give you such an option.

Once Windows is loaded in Safe Mode, your first action should be to attempt to fix the dll files by using the System Restore utility. This enables you to reverse some recent registry changes, system file deletions and such provided you had system restore turned on while your computer was working. After this you will need to reboot your machine again to see if it works normally.

Failing this you may need to re-install your operating system from the CD as most of the dll files will be replaced in this way.

Missing Dao350.dll Crashes Computers

Dao350.dll is an essential system file, critical to the proper running of Visual Basic Applications, particularly to those that work with databases. Yet many operating system installations, for various reasons, lack this critical component and, as such, crash when certain software applications are run. For example, while attempting to install a certain sports’ database related software, the computer in question displayed a number of error messages citing seemingly infinite numbers of errors in “data objects” and such.

This difficulty is easily remedied by obtaining the missing DLL file, whether from a friend’s computer, or online or from your relevant Windows CD and placing it in the system folder. Normally this is C:\WINDOWS\system32 but it may vary so do a search for the system32 folder if necessary. After pasting the DLL file in the folder you simply need to register it so that Windows can recognize its presence for use as follows:

1) Click ‘Start’, and then select ‘Run’

2) In the box provided type regsvr32 dao350.dll and press ‘Enter’

A message will notify you of your success and you may then re-launch the complaining application with confidence.
