Part II (A startup lesson on using FxCop)

In the previous article (FxCop Part I – Introduction), we saw the basics of FxCop , its definition, download path, comparison with other Code analysis tools, a simple demo for doing a analysis,etc.

In this article (Part II -A startup lesson on using FxCop), we are going to see the usage of FxCop at a beginner’s level.

As we saw in the previous article two things are required for doing any analysis in FxCop, they are:

· Assembly ( either a .exe or .dll)

· Rule

A brief explanation about the windows and menus in FxCop

Run FxCop by clicking , Start > All Programs > Microsoft FxCop > Microsoft FxCop 1.36

After the FxCop window was opened,

Click File > New Project.

The following Figure 1.0 shows the FxCop tool,

Fig 1.0

Panes in FxCop

There are 3 panes in the tool, they are:

· Main Pane

· Messages Pane

· Output Pane

Main Pane

Figure 1.1 shows the Main Pane,

Fig 1.1

It will have 2 tabs in it, they are

· Targets

· Rules

These two tabs serve the respective purpose of showing and managing targets and Rules in the current project.

Messages Pane

This Pane shows the messages that are generated by the FxCop tool after doing the Code analysis and it will be of various categories.

Figure 1.2 shows the Messages pane.

Fig 1.2

It will have 4 tabs in it they are,

· Active

· Exclude in Project

· Exclude in Source

· Absent

The usage of these we will see in the later articles.

Output Pane

This will show the properties in code format when an item is clicked on the Main Pane.

Figure 1.3 shows the Output Pane,

Fig 1.3

Menus

For the initial level, it is enough to know about the 3 menus in the tool. They are

1. File > New Project

It is used to create a new project.

2. Project > Add Targets

It is used to add assemblies from the Project on which you want to do the analysis.

3. Project > Analyze

To start the analysis, you need to click this or press F5 or click Analyze button on the toolbar.

A simple analysis:

1. Run FxCop.

Start > All Programs > Microsoft FxCop > Microsoft FxCop 1.36

2. File > New Project.

3. Project > Add Targets.

4. Select the desired assembly you want to analyze (it can either be a .dll or an .exe).

For example, I am selecting here a .net application (Which was downloaded from internet)

5. If you have selected multiple assemblies then select any one of them (the one you want to analyze first) and then click Project > Analyze or press F5 or Click Analyze from toolbar.

6. Analyzing with introspection Engine dialog box will appear when the analysis is under process.

7. Then it will display list of messages in the right pane.

The resultant window is what is shown in the Figure 1.0. The messages shown will be of the following categories, they are:

· Critical error

This means that it is an major issue and need to be corrected.

· Warning

This means it’s just a warning and not that much serious, but if corrected the it will be good.

More details about the messages:

Double click on the respective message, then Message Details window will appear, which gives a detailed explanation about the message along with other options.

That window will have 5 tabs in it which elaborates about he message and its dependencies.

Figure 2.0 shows the Message Details window,

Fig 2.0

Stopping the Analysis

Click the Cancel button on the Analyzing with introspection Engine dialog box to cancel the Analysis in the middle.

Viewing a summary of the Analysis

Click Project > Analysis Summary, it will display a summary of the analysis done.

Figure 2.1 shows the Analysis Summary window,

Fig 2.1

Saving the Project

After the analysis is over , save the project before saving the Message XML file otherwise it will throw an error.

Note:

Moreover save the Project file in the same directory of the Assembly for which the code analysis is done.

To save the project click,

File > Save Project.

Saving the Report

After saving the Project file, you a save the report file wherever you want.

To save the Report click,

File > Save Report

This might have given a basic idea about the usage and components of FxCop. We shall see more in the coming Chapters.
