| OLE Type Library | Microsoft | Misc Files |
The TLB file extension stands for OLE Type Library, a binary format developed by the Microsoft Corporation. This file type is used to store type library information required when building a program using the Component Object Model (COM) ActiveX technology.
Type libraries are dynamic-link libraries which contain definitions of objects, their properties and methods, OLE Automation classes, used as an interface reference in other programs. The TLB format is used by Component Object Model dynamic-link libraries, OLE Automation servers and controllers. Such libraries provide the developer with a description of COM objects used during the compiling process.
Relationship to Other File Formats
The TBK, OLB, and FWD files are related to the TLB format. These files contain a backup version of the type libraries which contain descriptions of COM objects, built before ActiveX controls existed. This enables applications to read values stored in these files.
Optimized Type Library Creation
Microsoft Visual C++, MIDL compiler, and other programs use the type library information stored in the TLB file when creating optimized type libraries. The MIDL compiler processes IDL declarations and generates source code for simple COM components containing type library information.
Creating/Viewing TLB Files
.NET Compiler Platform (Roslyn), an open source project for the .NET framework, includes tools for compiling source code written in C# or Visual Basic into executable programs. Additionally, the .NET Reflector, a free tool for decompilation and browsing.NET assemblies, can be used to view or save the contents of a TLB file.
Programs for WINDOWS system
Programs for MAC system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .TLB) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .TLB extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .TLB file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .TLB extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .TLB extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .TLB file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .TLB file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .TLB file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .TLB file) will be extended to the maximum.
It is also good to check
- if the .TLB file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
