Codeproject - Embedding .PNG images into a RichEdit document

[hutch--]

Magnus,

Have a look at an editor in MASM32 called "uniedit.exe". It ran on XP and if you are using an OS from Win7 upwards, all of the east Asian fonts are present. On XP you had to load language packs but not on later OS versions. QE is an ASCII code editor, it will never be multi-lingual.

Thanks
In a way qeditor becomes multilingual when it's used by a multilingual coder,comments in their native language,, 5000+Japanese unicodes in. Data section, use it for java

I have updated the article with a table of RichEdit controls by Windows OS and MS Office. People interested can also download the respective Excel sheet I am attaching here. I have also found a better way to advance the caret after embedding the image and have updated the article with that.

I have been talking that for older versions of the RichEdit we can embed .BMP files. I wasn't meaning display clickable links but show the real image. I also mentioned that it is difficult, in particular for bitmaps in the resources (it is easier when loaded from file or dropped from the clipboard). I know how to do it in C++ and in Delphi but I think it is extremely difficult to do it either in ASM or in C.
May be somebody want to try.  :idea:  :t

Let me answer to my own post  :lol:

I have solved it for C, which means that it is automatically solved for ASM, but I will not do it.

The real problem is that C does not handle classes.  However, C handles structures 

For people that want to try I will leave here a C++ reference link:

I will not post the C solution here, may be I will on CodeProject.

Those who want to see C, a simple example of InsertBitmap and IDataObject in C code.
It just insert a one bitmap to richedit.

Well done.  :t
People could confirm that there is no easy way to do it.

Excellent, Timo :t

What's the difference between the two versions? Attached a version by Mike Lytle, unfortunately I can't get it to work on my C installations. There is also the old MSDN Q220844: HOWTO: Insert a Bitmap Into RTF Document Using RichEdit Control

[TimoVJL]

Last one is just a bit cleaner ;)
How to Use OLE in Rich Edit Controls
EDIT: OleCreateFromFile() needs full path name.

That's it:

I have updated the article with a demo, now using the  TOM2's TextRange2::InsertImage() method.
The demo loads a text then when you press the button replace spaces with .pngs.





The demo is in C++, but is easily translated to C and then to ASM, as usual.  :lol:

The real difference between C++ and C, in this case, is in the syntax for calling the interface methods.
For example, in C++:
hr = pDocument2->GetSelection2(&pSelection2);
in C:
hr = pDocument2->lpVtbl->GetSelection2(pDocument2 ,&pSelection2);
In ASM, using the coInvoke macro, it will become similar to the C syntaxe. If you don't use the coInvoke macro, it is a lot of fun but is difficult to figure out.

Nice demo. Your program is Windows 8+ only, though. Depending on the Office installation, a Win7 user (like me) may find the ITextRange2 interface in C:\Program Files (x86)\Common Files\Microsoft shared\OFFICE12\RICHED20.DLL but not in C:\Program Files (x86)\Common Files\Microsoft shared\OFFICE12\RICHED20.DLL

[aw27]

I don't know if the problem for Windows 7 is the ITextRange2 or the ITextSelection2 interface, would need to check. I have used the ITextSelection2 to reach the ITextRange2 but it can be reached as well from the ITextDocument2.
You may be right, although I have doubts you can use InsertImage from pRange2 with Office 2007/Office 12. It is so old.

MS Office 2013 riched20.dll is version 8, insert image works.

Code Select Expand

const GUID IID_ITextDocument2={0xC241F5E0,0x7206,0x11D8,0xA2,0xC7,0x00,0xA0,0xD1,0xD6,0xC6,0xB3};
IID_ITextDocument2 was exported from that dll.
In TLB InsertImage was hidden by missing line after GetMathFunctionType()

Code Select Expand

HRESULT (STDMETHODCALLTYPE *InsertImage)(ITextRange2 *This,LONG,LONG,LONG,LONG,BSTR,IStream*);a silly test

Code Select Expand

if (pDocument) {
IStream *pStream = NULL;
ITextRange2 *pTextRange2;
HRESULT hr = SHCreateStreamOnFile(L"test.png", STGM_READ | STGM_SHARE_DENY_NONE, &pStream);
hr = pDocument->lpVtbl->Range2(pDocument, 0, 0, &pTextRange2);
hr = pTextRange2->lpVtbl->InsertImage(pTextRange2, 1000, 1000, 0, 0, L"test.png", pStream);
}
BTW: Tested in Windows 7.

For Office 2016, and probably 2019, InsertImage was the latest method added to ITextRange2. It seats just after GetMathFunctionType.
I have an old computer with Office 14 and its Riched20.dll has no InsertImage method. The latest one is GetMathFunctionType.

[TimoVJL]

If EM_INSERTIMAGE works, InsertImage might be there too.
15.0.4693.1000 was under test.
