When executing a program that was created using Visual Basic 6.0 and a SocketTools ActiveX control, the following error is returned: Run-time error 424: Object required. This error can occur if the control is not properly registered on the local system, or if the object has not been referenced correctly.

SocketTools 9 includes Windows Installer (MSI) packages which enable you to easily redistribute the components used in your projects. They are included with the developer installation package for each edition and available for both 32-bit and 64-bit applications.

When you create an application using the SocketTools Library Edition DLLs and you're ready to deploy it, you must ensure the libraries you're using are initialized correctly. This is done by providing a runtime license key to the initialization function for each of the SocketTools APIs you are using. It is important to note your

When you create an application using the SocketTools ActiveX Edition controls and you're ready to deploy it, you must ensure the controls you're using are initialized correctly. If you are developing with Visual Basic 6.0, and you've placed the controls on a form, it will automatically initialize the controls when the form is loaded.

When you create an application using the SocketTools .NET Edition components and you're ready to deploy it, you must ensure it is initialized correctly. This is done by either providing a runtime license key to the Initialize method, or setting the RuntimeLicense attribute for the executable assembly. It is important to note your runtime license

This article discusses several methods for exchanging structured messages over stream-based TCP sockets.

The SocketTools server components can use self-signed certificates to enable secure connections without requiring that you purchase and install a certificate from a Certificate Authority. These certificates are installed on the local host, and are typically used for testing purposes. However, when attempting to connect to the server using Chrome or Firefox, an error is

SocketTools includes several server components, including a multi-threaded HTTP server. Initial testing is often done with the client and server connecting to one another on the local system, rather than over the Internet. When using the Chrome, Firefox or Internet Explorer browsers, the connection to the local server is successful. However, connection attempts fail when

When attempting to manually register a control from the command line using the RegSvr32.exe utility, an error is displayed stating that the ActiveX control was loaded but the call to DllRegisterServer failed with error code 0x80040200.

There are a few important development considerations when exchanging binary data over a network connection. For most applications, strings should never be used to send or receive binary data; instead, applications should use byte arrays to exchange binary data.
