Re: Save/use page margins in RichEdit .rtf docs?

Hi Roy,

My app already saves and retrieves the last Printmargin properties using the Registry, but this doesn't solve the problem because users want different print margins for different types of documents, and they can't be expected to remember what margins they set for which document. Further, there's no way of knowing if a user has either used another app to create a doc with margins different from my app's Printmargin settings or modified a doc's margins with another app before opening/reopening the doc with my app. These are the reasons margins need to be associated with (part of the {\rtf1...} info in) each document!
Here's my wish list:
1) I want to have each .rtf document's Printmargins properties automatically saved with the document, i.e., in the {\rtf1...}"header" info the way Word does using \margl..., \margr..., \margt..., and \margb....
2) When a document is opened, I want the \marg... info (if any) in the document to be used to set the Rich Edit's Printmargins properties automatically. If no \marg... info exists in the header, then the Rich Edit's current Printmargin properties should be used.
3) Tall order: It would be very helpful to users if there were a way to show where page breaks occur (like Word does). Right now, the user has to print the doc to see how the margin-dependent pagination will come out. IMHO, this is a severe (and annoying) limitation.
4) My compromise for #3 is going to be to add a print preview capability to my app's Rich Edit functionality. Hint, hint. <g>
Since IP's Rich Edit doesn't save and retrieve each .rtf doc's Printmargin properties automatically, I'm going to have to go through interim steps (hidden from the user) of getting the doc in plain text form to save and retrieve margin info. For example:
if Open New doc then    set Printmargin properties from my app's Registry keys else if Open Existing doc then begin    get doc in plain text format (hidden from user);    scan the doc's {\rtf1...} info to see if \marg... info exists;    if \marg... info is found then       set Printmargins properties using the \marg... info    else       set Printmargin properties from app's Registry keys;    display doc to user in rich text format; end; if Save as rich text format then begin    put the doc in plain text format (hidden from user);    if {\marg...} info does not exist in header then       insert {\marg...} info using Printmargin properties    else       modify {\marg...} info using Printmargin properties;    save the doc in rich text format; end;
So far I've found that if I use Notepad to insert a {\margl...\margr...\margt...\margb...} clause in the header of an rtf doc that was created with IP's Rich Edit, Word will ignore the margin info if I don't do it according to how Word is expecting it. I haven't yet figured out what I need to do to make Word accept \marg... info I've inserted this way. (I don't have the .rtf syntax rules.)
If you have any suggestions for how I can accomplish what I want, I'll be glad to hear them! Otherwise, I'll continue slogging ahead on my own--unless you tell me you're going to implement my wish list fairly soon. Then I'd have to upgrade from IP4! <g>
