Component Checker is a tool that allows you to determine the version installation information of the Microsoft Data Access Components (MDAC), and assists in diagnosing installation issues with MDAC. MDAC is installed with numerous Microsoft products and also is available for redistribution by other application providers.
Note:
|
Component Checker can only be used on 32-bit platforms of English language. In addition, Component Checker requires Microsoft XML Parser (MSXML) to operate correctly on your computer. If MSXML is not present on your system, you must install MSXML 2.0 or newer from or from the .
|
Component Checker performs the following tasks:
· Identifies the MDAC installations.
· Creates a report about the files identified for the MDAC installations.
1. Running Component Checker |
|
There are two ways to run Component Checker:
· You can run Component Checker as a Windows application by double-clicking the application icon (or the cc.exe file) in the installation directory. In this mode, you can use the tool to perform a variety of simple evaluations using the menus in the main application window.
· You can also run Component Checker from the command prompt. Running the tool from the command prompt allows you to specify various command line options.
1.1 Running Component Checker from the User Interface |
|
Regardless of whether you start Component Checker from Windows or from the command prompt, the user interface will appear (unless the /q command line option is used, which causes Component Checker to run in silent mode, with no user interface). When launched, Component Checker first displays the S dialog box, where you choose from one of three analysis options. Based on your selection, the results are then displayed in the Component Checker window.
Choosing an Analysis Type
The Choose Analysis Type dialog box allows you to choose one of three options:
· Perform analysis of your machine and automatically determine the release version (Default)
When selected, this option searches the Microsoft Data Access Components (MDAC) installation on your computer and determines its released version. Because it is possible that different products may have installed different versions of MDAC, the result of this analysis might not be precise. Component Checker, however, presents the version that most closely matches the currently installed components.
· Perform analysis against a selected version
When selected, this option activates a drop-down list of all versions of MDAC ranging from version 2.1 SP2 to the most recent. Component Checker will perform an analysis based on the version selected and then present a list of error or warning messages.
· Scan your machine. Do not perform an analysis
When selected, this option performs an analysis on the data from the last analysis, and presents the Component Checker window. Any results, errors, or warnings will appear here.
1.2 Running Component Checker from the Command Prompt
|
|
Many operations of Component Checker can be implemented by running the tool from the command prompt. The following table lists the command line options that invoke these operations. See the following Examples section for usage illustrations.
Option
|
Operation
|
/?
|
Displays the command-prompt Help.
|
/o
|
Specifies the output file name and path.
|
/n
|
Used in conjunction with the /o option. Filters output details using one of the following values:1 = File2 = Registry3 = File and Registry4 = COM5 = File and COM6 = Registry and COM7 = File, Registry, and COM
|
/s
|
Scans for a specific version of MDAC.
|
/c
|
Scans for the closest, or most recent, version of MDAC.
|
/a
|
Scans for all MDAC versions.
|
/q
|
Runs Component Checker in quiet mode, meaning that the user interface of the tool is not displayed.
| Examples
The following examples show how to use the Component Checker command line options.
Example 1
The following example analyzes your computer and directs the output to a file named AllVersions.xml in the installation directory. This file contains a full report that lists the file, registry, and COM information for all versions of MDAC found to be installed locally.
cc /a /o AllVersions.xml /q
| Example 2
The following example analyzes your computer against MDAC 2.8 RTM. It produces a report file named SpecificVersion.xml in the installation directory.
cc /s "MDAC 2.8 RTM" /o SpecificVersion.xml /q
| Example 3
The following example detects and analyzes your computer against the closest version of MDAC in its internal list. It outputs a full report of its findings to a file named ClosestVersion.xml in the installation directory.
cc /c /o ClosestVersion.xml /q
|
2. Analyzing Component Checker Results |
|
When Component Checker is used to analyze the currently installed versions of the Microsoft Data Access Components (MDAC), the results from the analysis are reported in the user interface, and in an output file named results.xml (also known as the results file).
Component Checker determines the version of MDAC on your computer based on versions of the core MDAC files it finds. If a given version has more version matches than any other version, the program displays a "closest version detection" message.
If multiple matches of the same version exist on your computer, Component Checker displays a "multiple version detection" message. You can then run the analysis against a selected version in the Choose Analysis Type dialog box.
2.1 Interpreting Results from the User Interface
|
|
The Component Checker application window consists of two panes that show the results of an analysis: the tree view pane on the left and the results pane on the right. Each item in the tree view pane, when selected, shows specific results in the results pane.
In addition, the View menu in the main application window allows you to select the details that you wish to view, including the following:
View
|
Description
|
Summary Report
|
The default view that is displayed after performing an analysis. Contains information about the Microsoft Data Access Components (MDAC) installations, including the file details.
|
File Details
|
Contains information about all of the MDAC files that were found during the analysis.
|
COM Details
|
Contains information about the Component Object Model (COM) files found during the analysis.
|
Registry Details
|
Contains information about the MDAC registry values found during the analysis.
|
You can save the information returned during the Component Checker analysis by selecting Save from the File menu. This will open the Save File dialog box that you can use to specify the path and file name to save the results to. The default name of the output file is results.xml, and the information that it contains is in an XML format.
2.2 Interpreting Results from the Results File
|
|
Component Checker logs the results of its analysis in an XML output file named results.xml; the results file can be saved to a folder of your choosing by selecting Save from the File menu, or by using the /o option if running the tool from the command prompt.
The results file created by Component Checker has a similar format to the input XML files contained in the \inputstream subdirectory, such as filestream.xml, registrystream.xml, and comstream.xml.
Additionally, the results file includes values for the element to contrast with the information obtained from the input files about a file, its registry value or COM object registration, and its version-specific details. Additional information in the results file includes:
· Descriptions of the contents of the file, including any descriptive comments or summary text.
· Status information when the file, registry value, or COM registration has errors or passes when checked for consistency to the version of MDAC being analyzed.
· Error strings when an error occurs in analyzing the version of MDAC.
· Date stamps (which is the date when the MDAC file was stamped or last touched) when they do not match what is stated in the input files for the corresponding file or registry value.
The results file can be viewed as text or XML markup using a text editor or Web browser.
3. Customizing Component Checker |
|
Customizing Component Checker allows you to better analyze and manipulate Microsoft Data Access Components (MDAC). You can configure Component Checker for different users and put safeguards in place for each.
You can:
· Modify the data in input files that are used by Component Checker to analyze MDAC components.
· Redirect component search results to an output file.
· Control the file list that Component Checker uses for analyzing MDAC components.
3.1 Modifying Data in Component Checker Input Files
|
|
The input data files for Component Checker control the Microsoft Data Access Components (MDAC) files to be analyzed. They also contain lists of registry values, COM information, and potentially other types of configuration data associated with installing and servicing the various versions of MDAC that have been released by Microsoft.
File Locations
Component Checker relies on files installed with it to determine MDAC file locations. The input data files are located in the \inputstream subdirectory where Component Checker is installed.
Most files used for customization are located in \inputstream. The following table lists the significant files, their locations, and use.
