Insert RTF into existing document

[Unregistered]

Hi.

Here's my situation. I've got a TextControl with an rtf file open in the control. I'd like to insert an rtf string into that document.

The catch is the rtf header on the rtf string. I don't have one. I just have the body of the rtf.

Any suggestions on how I can load that rtf string? Is there a way I can grab the header of the open rtf file, add it to the rtf string, and load that?

Ideas? Suggestions?

You can create a simple file in WordPad then open it with Notepad to get a dummy header. Copy it once into your program as a string to add to your own text, something like

RtfHeader = "{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl {\f0\fswiss\fcharset0 Arial;}}"

MyRtfBuffer = RtfHeader + MyRtfText + "}"

You can save the current doc to memory / string and try to find the end of the header manually but that can be tricky.

Or a brute force approach:
- Insert a marker string at the insertion point, for example "-=$=mark=$=-"
- save the doc to memory
- split the doc string into before-the-mark and after-the-mark
- combine before + new-text + after
- replace the entire document

Hopefully someone else can suggest something more elegant :-)

Thanks Dave -- I'm going to give it a try . . .

One question -- how would I do this part:

- split the doc string into before-the-mark and after-the-mark

while the doc is in memory?

Thanks . . .

Depends on the language, what are you using?

In C++ strstr() to find the mark, in VB6 I forget what the function is to find the index of one string within another string. You'd split with left() and mid(). I think the VB6 online help will have some sample code under "string functions" or similar.

I'm using VB.

SaveToMemory returns a byte array, not a string. So I can't use VB's string functions.

Right now I'm trying to do it by loading the rtf document as ANSI text (format 1) into another text control . . . then insert the text into the second text control . . . then reload it as rtf into the first control.

But it aint working. I have more work to do on it however.

Could you Paste the data into the existing document.

Matt --

I was able to get this to work using a hidden text control.

I put a marker string at the location where I want the rtf to be inserted (eg, !!!+marker+!!!). I save the current document to memory as an rtf file. I then load it in the hidden text control as a plain text (Format =1).

I replace the marker with the rtf bit that I want to insert. I turn this document into a byte array, and then use LoadFromMemory to reload it into the visible text control.

Hope someone finds that useful.
