First, we proposed putting the most important corporate cash flow measures in summary on the left panel. Then, at the top of the main area, we showed two charts for displaying monthly inflow and outflow as well as ending cash value. We suggested that the designers use a data chart of module series to not only display monthly cash flows, but also allow users to select a particular month right from the chart. Clicking the left or right arrow on the main chart will scroll the chart to a different time range. Notice that the cash flow of data does not change while scrolling, but as expected, the data will be changed if a different month is clicked.

Category : Windows 8 dll. Additionally, when you run a program on one of these Windows operating systems, much of the functionality of the program may be provided by DLLs. For example, some programs may contain many different modules, and each module of the program is contained and distributed in DLLs. The use of DLLs helps promote modularization of code, code reuse, efficient memory usage, and reduced disk space.
Therefore, the operating system and the programs load faster, run faster, and take less disk space on the computer. When a program uses a DLL, an issue that is called dependency may cause the program not to run. When a program uses a DLL, a dependency is created. If another program overwrites and breaks this dependency, the original program may not successfully run.
With the introduction of the Microsoft. NET Framework, most dependency problems have been eliminated by using assemblies. What is a DLL? A DLL is a library that contains code and data that can be used by more than one program at the same time. For example, in Windows operating systems, the Comdlg32 DLL performs common dialog box related functions.
Therefore, each program can use the functionality that is contained in this DLL to implement an Open dialog box. This helps promote code reuse and efficient memory usage. By using a DLL, a program can be modularized into separate components. For example, an accounting program may be sold by module. Each module can be loaded into the main program at run time if that module is installed.
Because the modules are separate, the load time of the program is faster, and a module is only loaded when that functionality is requested. DLL Diagnostics Tool. Additionally, updates are easier to apply to each module without affecting other parts of the program.
For example, you may have a payroll program, and the tax rates change each year. When these changes are isolated to a DLL, you can apply an update without needing to build or install the whole program again. Control Panel. Each item is a specialized DLL. Device driver. DLL advantages.
The following list describes some of the advantages that are provided when a program uses a DLL: Uses fewer resources When multiple programs use the same library of functions, a DLL can reduce the duplication of code that is loaded on the disk and in physical memory. This can greatly influence the performance of not just the program that is running in the foreground, but also other programs that are running on the Windows operating system.
Promotes modular architecture A DLL helps promote developing modular programs. This helps you develop large programs that require multiple language versions or a program that requires modular architecture.
An example of a modular program is an accounting program that has many modules that can be dynamically loaded at run time. Eases deployment and installation When a function within a DLL needs an update or a fix, the deployment and installation of the DLL does not require the program to be relinked with the DLL. Additionally, if multiple programs use the same DLL, the multiple programs will all benefit from the update or the fix.
This issue may more frequently occur when you use a third-party DLL that is regularly updated or fixed. DLL dependencies. Therefore, the program is no longer self-contained, and the program may experience problems if the dependency is broken. For example, the program may not run if one of the following actions occurs: A dependent DLL is upgraded to a new version. A dependent DLL is fixed. A dependent DLL is overwritten with an earlier version. A dependent DLL is removed from the computer.
These actions are generally known as DLL conflicts. If backward compatibility is not enforced, the program may not successfully run.
The following list describes the changes that have been introduced in Microsoft Windows and in later Windows operating systems to help minimize dependency issues: Windows File Protection In Windows File Protection, the operating system prevents system DLLs from being updated or deleted by an unauthorized agent. Therefore, when a program installation tries to remove or update a DLL that is defined as a system DLL, Windows File Protection will look for a valid digital signature. Private DLLs use version-specific information or an empty.
Then, for new programs, add version-specific information to the DLL. For old programs, use an empty. Each method tells the operating system to use the private DLLs that are located in the program root folder. This section describes the issues and the requirements that you should consider when you develop your own DLLs.
Types of DLLs. The two methods of linking are load-time dynamic linking and run-time dynamic linking. Load-time dynamic linking In load-time dynamic linking, an application makes explicit calls to exported DLL functions like local functions.
To use load-time dynamic linking, provide a header. When you do this, the linker will provide the system with the information that is required to load the DLL and resolve the exported DLL function locations at load time.
When you use run-time dynamic linking, you do not need an import library file. The following list describes the application criteria for when to use load-time dynamic linking and when to use run-time dynamic linking: Startup performance If the initial startup performance of the application is important, you should use run-time dynamic linking.
Ease of use In load-time dynamic linking, the exported DLL functions are like local functions. This makes it easy for you to call these functions. Application logic In run-time dynamic linking, an application can branch to load different modules as required.
This is important when you develop multiple-language versions. The DLL entry point. When you create a DLL, you can optionally specify an entry point function. The entry point function is called when processes or threads attach themselves to the DLL or detached themselves from the DLL. You can use the entry point function to initialize data structures or to destroy data structures as required by the DLL. Additionally, if the application is multithreaded, you can use thread local storage TLS to allocate memory that is private to each thread in the entry point function.
The following code is an example of the DLL entry point function. When the entry point function returns a FALSE value, the application will not start if you are using load-time dynamic linking. If you are using run-time dynamic linking, only the individual DLL will not load.
The entry point function should only perform simple initialization tasks and should not call any other DLL loading or termination functions. For example, in the entry point function, you should not directly or indirectly call the LoadLibrary function or the LoadLibraryEx function. Additionally, you should not call the FreeLibrary function when the process is terminating. Note In multithreaded applications, make sure that access to the DLL global data is synchronized thread safe to avoid possible data corruption.
To do this, use TLS to provide unique data for each thread. Exporting DLL functions. To export DLL functions, you can either add a function keyword to the exported DLL functions or create a module definition.
You can also use a module definition file to declare exported DLL functions. When you use a module definition file, you do not have to add the function keyword to the exported DLL functions.
The following code is an example of a definition file. In run-time dynamic linking, you use code that is similar to the following code to call the SampleDLL. The Windows folder. NET Framework assembly. With the introduction of Microsoft. NET and the. An assembly is a logical unit of functionality that runs under the control of the. An assembly physically exists as a.
An assembly file contains an assembly manifest, type metadata, Microsoft intermediate language MSIL code, and other resources. The assembly manifest contains the assembly metadata that provides all the information that is required for an assembly to be self-describing.
The following information is included in the assembly manifest: Assembly name Version information Culture information Strong name information The assembly list of files Type reference information Referenced and dependent assembly information The MSIL code that is contained in the assembly cannot be directly executed. By default, when you create an assembly, the assembly is private to the application.
To create a shared assembly requires that you assign a strong name to the assembly and then publish the assembly in the global assembly cache. The following list describes some of the features of assemblies compared to the features of Win32 DLLs: Self-describing When you create an assembly, all the information that is required for the CLR to run the assembly is contained in the assembly manifest.
The assembly manifest contains a list of the dependent assemblies. Therefore, the CLR can maintain a consistent set of assemblies that are used in the application. Versioning In an assembly manifest, version information is recorded and enforced by the CLR. Additionally, version policies let you enforce version-specific usage. In Win32 DLLs, versioning cannot be enforced by the operating system. Instead, you must make sure that DLLs are backward compatible. Side-by-side deployment Assemblies support side-by-side deployment.
