When you have installed your ShellDispenser-Dev license, you can insert the license details into your project. You can do this by opening the ShellDispenser-Dev.lic file in a regular text editor like Notepad, and integrate the entire content into your project. Depening on your development environment this can be done in several ways; it is almost always possible to add the license details as a string, but it might also be possible to add the license as a "resource".
Some details to pay attention to when copying your license data are line endings and the used character set. The line endings must all be taken over identically; the expected line endings are the default Windows line endings (a Cr/Lf combination). In VB(A) you can use the constant vbNewline for this, in C / C++ you must use the string "\r\n". The used character set should be UTF16 (Unicode); VB(A) already uses this by default, but in C / C++ you must use wchar_t's.
When you have integrated your license details into your project, you can load the data into a variable and then pass it's content to the "SDD_Initialize" function.
