Picture embedding is supported through the ALLText External Object DLL, atx45pic.dll, provides full support for the direct embedding of images. No external OLE server is required. Supported picture formats include: BMP, DIB, WMF, JPG, and ICO. atx45pic.dll is responsible for the initial embedding of pictures, as well as for the manipulation of the objects: setting picture properties, displaying, printing, saving, restoring etc.

RegNewExtern Method |
Description: Loads specified external Object DLL and registers it with ALLText.
Syntax:
Parameters:
Example:
Returns:
Remarks: External object DLL`s must be registered before they can be used. They only need to be registered once each time the ALLText control is loaded into memory (not for each instance, or even for each form containing ALLText).
|
OLEObject Property |
Description: Setting this property causes ALLText to call the specified External Object DLL to create and embed an External Object (eg: OLE Object or Picture) at the current caret location, overwriting any currently selected portion of the document. The type of object created is specified by the assigned string, ObjName$.
When read, this property returns a string indicating the name of the External Object DLL (atx45pic, atx45ole,...) supporting the object and an object number. If the object is an OLE object and the OLEVerb is set to anything other than ATX_Verb_Undefined, the OLE Server will be launched to executes this verb (ATX.OLEVERB) on this object. Note that this is true only for objects found immediately after caret, or an object marked with ink grabber frame when using ALLText/Pen.
The name of this property is a hold over from earlier versions of ALLText. In truth, the OLEObject property only initiates an OLE Link when calling the ATXOLE.DLL External Object DLL. Other external object libraries do not rely upon of OLE technology.
