I use WeBrowse Control to embed DWG TrueView in WinForm. But DWG TrueView opens not in WebBrowse , only outside in new window. I had the same problem with Microsoft Word. Also Word was opened in new Window. This problem solved. I changed registers value. Below Examples.
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.Document.8] "BrowserFlags"=dword:80000024
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.RTF.8] "BrowserFlags"=dword:80000024
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.Document.12] "BrowserFlags"=dword:80000024
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.DocumentMacroEnabled.12] "BrowserFlags"=dword:80000024
I think that the same I should do with DWG TrueView. But somebody known wchich register should I change and what value should be assigned ??
