How do I dynamically load a control from an assembly (or DLL)?

General - Windows Forms FAQs
You use System.Reflection to dynamically load a control. This sample loads the SpecControls.ColorControl from SpecControls.dll. [C#] using System.Reflection; Assembly assembly = Assembly.LoadFrom( "SpecControls.dll" ); Type t = assembly.GetType...

Can I load a module dynamically ?

FAQ about language spec of MixJuice
Since there are class inheritance and module inheritance as the differential programming mechanisms redundantly, I am not certain which mechanism should be used. The class inheritance should be used with is-a relations, and it should not be used as a tool for differential programming without careful consideration. On this point, MixJuice is same with C++ or Java.

How to I load different subsequences dynamically?

TestStand FAQ - Support - National Instruments
Subsequence calls can be defined statically or dynamically in TestStand. Dynamically loaded subsequences can be in the same sequence file as the caller sequence, or in different sequence file. The Specify Module dialog box for a subsequence call has a checkbox labeled "Specify Expression for Pathname and Sequence" to choose whether the sequence will de defined statically or dynamically. For more information on dynamic sequence loading, consult Chapter 12 of the User Manual: Module Adapters.

How do I trace a dynamically loaded shared library (DLL)?

RootCause/Aprobe FAQ
You must add the library to the workspace, and then it will show up in the Trace Setup window. To do this, select Add Dynamic Module... from the Workspace menu. If the module changes, you must do Reset Dynamic Module .

Can I load CSS stylesheets dynamically at runtime?

Flexcoders FAQ
Dynamic loading of CSS files is not supported in Flex. CSS in Flex is processed on the server side during MXML compilation rather than on the client side at runtime. There is a trick though: a CSS file can be compiled into a separate SWF file and loaded dynamically into the application using the Loader component.

What is an assembly?

Andy Mc's .NET Framework FAQ
assembly is sometimes described as a logical .EXE or .DLL, and can be an application (with a main entry point) or a library. An assembly consists of one or more files (dlls, exes, html files etc), and represents a group of resources, type definitions, and implementations of those types. An assembly may also contain references to other assemblies. These resources, types and references are described in a block of data called a manifest.

Can I load an appender from another assembly?

Apache log4net - Apache log4net: Frequently Asked Questions
Yes. When specifying the type in the configuration file you can give the assembly qualified name of the type. For example: The .NET runtime will try to locate the assembly called MyAssembly. How .NET locates assemblies is beyond the scope of this FAQ. When loading an assembly from the GAC the fully qualified assembly name, including the version, culture and public key must be specified. This is in the standard syntax supported by System.Type.GetType.

Can I dynamically load C user routines?

Perl FAQ
Yes -- dynamic loading comes with the distribution. That means that you no longer need 18 different versions of fooperl floating around. In fact, all of perl can be stuck into a libperl.so library and then your /usr/local/bin/perl binary reduced to just 50k or so. See DynaLoader(3pm) for details. In perl4, the answer was kinda. One package has been released that does this, by Roberto Salama*. He writes: Here is a version of dylperl, dynamic linker for perl.

What to do about a 3633 Can't load DLL: MSJET35.DLL error?

Frequently Asked Questions

How easy is it to dynamically change the HTML control for a field?

FAQ on the Radicore Development Infrastructure
This situation arose while I was building a prototype for a web-base survey application. A survey could have any number of questions, and the answer to each question could be one of the following: This means that when building the HTML output for the screen I need to know what type of answer is expected so that I can generate the correct HTML tags. In some development infrastructures this may be a complex process, but in my infrastructure it is incredibly easy.

What do we get from the DLL?

ECE 554
From the app. note above, DLL provides either the divided clock or the multiplied clock depending on what it is programmed and other phases, 90, 180, 270-degree, of the target clock. That's because of the minimum freq required by the DLL. High clock freq may cause the implementation tool to fail.

What does 'DLL attempted to change FPU control word' mean?

R for Windows FAQ
This is a warning which indicates that R has taken action to correct the action of some (non-R) DLL which has just been loaded and has changed the floating point control word (in its initialization code) to a setting incompatible with that needed for R. This is not good practice on the part of the DLL, and often indicates that it needs to be updated. (It was common with DLLs compiled in early versions of Visual C++.

I'm getting a DLL error message trying to load the PocketPC Emulator, how can I fix this?

FAQ
This is because of DEP support in Windows XP SP2. If you don't know what these terms are, please use google! This problem will usually only occur during the first few weeks of semester. If you spot the problem and re-imaging your PC doesn't fix it, email the student-helpdesk so we know it's happening and can fix it! In the meantime however, to fix this issue if you come across it, please edit the C:\boot.

How can I produce an assembly?

Andy Mc's .NET Framework FAQ
The simplest way to produce an assembly is directly from a .NET compiler. For example, the following C# program: public class CTest { public CTest() { System.Console.WriteLine( "Hello from CTest" ); } } You can then view the contents of the assembly by running the "IL Disassembler" tool that comes with the .NET SDK. Alternatively you can compile your source into modules, and then combine the modules into an assembly using the assembly linker (al.exe).

Can I dynamically specify configuration values?

DenyHosts Frequently Asked Questions
Starting with DenyHosts version 2.2, you can now specify all or part of a configuration value to use an environment variable setting. To specify a dynamically substituted value you specify the portion of the value you would like to replace using the syntax $[ ... ] where the ... maps to an environment variable name. Notes: the environment variable must be specified in UPPERCASE and will be retrieved from the local environment when DenyHosts is started.

How will you load dynamic assembly? How will create assemblies at run time?

Mail Test
What is Assembly manifest? what all details the assembly manifest will contain. Every assembly, whether static or dynamic, contains a collection of data that describes how the elements in the assembly relate to each other. The assembly manifest contains this assembly metadata.

How do I load more than 64K into an edit control?

MFC Visual C++ FAQ version 4.0 Windows Programming OLE VBX O...
The Rich Edit Control available in VC++ 2.1+ supports much more than 64k. The Wordpad sample is a great way to learn more about this subject. If you're stuck with 16-bit programming, I think that magma systems has a 16-bit DLL that does this. Contact Marc Adler at: 75300.2062@compuserve.com for details.

Why is Load Factor control important?

Unofficial Technocracy FAQ Ver. 1.2 (HTML)
The extreme inefficiency of present low load factors is a major reason for many current difficulties, most of which could be overcome by scrapping much equipment and raising the operating load factors on the remainder to the highest possible degree. Rather than suffering loss from such action, the public would experience a considerable gain in services rendered.
