Technical Exegesis...
Sets the HTML content of an HTMLView control directly from a string. Searches webBrowserMap for htmlViewID. If found, gets IWebBrowser2* interface. Navigates to "about:blank" to create empty document. Sleeps 100ms to allow document initialization. Gets IDispatch via get_Document(), then queries for IHTMLDocument2 interface. Converts UTF-8 htmlContent string to BSTR using MultiByteToWideChar. Creates SAFEARRAY with SafeArrayCreateVector(VT_VARIANT, 0, 1). Stores BSTR in array element.

Converts UTF-8 htmlContent string to BSTR using MultiByteToWideChar. Creates SAFEARRAY with SafeArrayCreateVector(VT_VARIANT, 0, 1). Stores BSTR in array element. Calls pDoc->write(psa) to inject HTML content. Calls pDoc->close() to finalize document. Releases COM interfaces. No return value.
This function loads inline HTML content into the WebBrowser control without needing external files or URLs. Navigation to about:blank creates blank document context. Sleep(100) is necessary because Navigate is asynchronous - without it, get_Document may return NULL or incomplete document. IHTMLDocument2 interface provides document manipulation methods. write() method injects raw HTML into document stream. close() finalizes the stream and triggers rendering. UTF-8 to BSTR conversion handles international characters. SAFEARRAY is COM's safe array structure required by write(). Complete HTML documents should include <!DOCTYPE html>, <html>, <head>, <body> tags. Partial HTML fragments work but may render inconsistently. JavaScript in content executes automatically. CSS styles apply normally. Use for dynamic content generation, templating, or offline HTML display.
