Gifolecontrol 1.0.2 Function Description

Gifolecontrol can insert images, including BMP, JPG, and PNG. The image size is not limited. The key point is that GIF animation can be inserted in RichEdit. Currently, swf format cannot be inserted. At the same time, you can directly display tooltip In the inserted image and GIF to facilitate the application.

 

The interface defined by gifolecontrol is as follows:

 

Interface igifctrl: idispatch {
[Propput, Bindable, requestedit, ID (dispid_bordercolor)]
Hresult bordercolor ([in] ole_color CLR );
[Propget, Bindable, requestedit, ID (dispid_bordercolor)]
Hresult bordercolor ([out, retval] ole_color * pclr );
[Propget, Bindable, requestedit, ID (dispid_hwnd)]
Hresult hwnd ([out, retval] long_ptr * phwnd );
[ID (1), helpstring ("method loadfromfile")] hresult loadfromfile ([in] BSTR bstrfilename );
[ID (2), helpstring ("method loadfromfilesized")] hresult loadfromfilesized ([in] BSTR bstrfilename, [in] int nheight );
[ID (3)] hresult getrect ([out] rect * RC );
[ID (4)] hresult showhint ();
[ID (5)] hresult sethostwindow ([in] Long hwndhostwindow, [in] int nnotyfymode );
[ID (6)] hresult loadflash ([in] BSTR bstrfilename, [in] BSTR bstrflashvars, [in] int nwidth, [in] int nheight );
[ID (7)] hresult settooltip ([in] BSTR bstrhint );
[ID (8)] hresult gettooltip ([out, retval] BSTR * bstrhint );
[ID (9)] hresult getfilepath ([out, retval] BSTR * bstpath );
};

Through the COM component, the demo is as follows:

 

The following describes how to use the control, including: 1. Use it in the dialog box; 2. Use it in RichEdit.

1. In the dialog box, use:

First, register the control gifolecontrol. dll, copy gifolecontrol. DLL to the system directory, and then use the command regsvr32 gifolecontrol. DLL to register the control.

In the dialog box resource editor, right-click and select "insert ActiveX control", select "gifctrl class", and insert the control. Right-click the inserted ActiveX Control and select "add variable" to generate the corresponding packaging class and corresponding instance, so that you can call the object method.

2. Use in RichEdit

The methods used in RichEdit are basically the same as those in the previous article. You only need to replace the corresponding classes and function calls. However, you can directly use the interface and interface guid definition here. The specific code is as follows:
