1-i need create a user control for show pdf inside of my user control without use any other ocx.
and i want can use load pdf from resource (res) or stream like file binary or ... .
any way ?
2-any any way to can create pdf too with choose font(important) and choose utf page or unicode options.
Why did you create this as a poll? It's a valid question, but not much of a poll.

i downloaded pdfstreamdumper but this is just hexa editor,how can see pdf on form ? and how can write pdf with utf 8 support?
my problem not fixed yet,any have sample code like user control for display pdf without use acrobat reader componenets or like it?
i want display pdf just use from my user control or i want created pdf file utf8 support.
Did you actually read the answer of dz32??
It's a tremendous job!
Do you have a good reason not to use existing solutions?
any sample code or sample user control for read pdf or write pdf (utf support) without other ocx like acropdf or office viewer or ... ?
As already stated by Arnoutdv - the pdf-spec is *enormous* (hundreds of "tags" with dozens of different parameter-options,Quote:

1) A PDF-Writer (which translates incoming DrawingCommands +their Parameters to text-based "PDF-tag-outputs") is *much* easier to implement
..(because it only has to use a small subset of all the available "tags" and "options" which make up the pdf-spec)
e.g. Cairo (and thus also the RC5) support pdf-writing in that way (translating all incoming cairo-drawing-comands into appropriately concatenated PDF-txt-stream-Snippets)
2) On the other hand, a (decent!) PDF-Reader has to support *all* (or nearly all) of the possible options of the pdf-spec (which is heavily based on the PostScript-spec in turn).
That's why PDF-Reader-Libraries tend to be that large.
And no, there is currently no VB6-Sources for decent PDF-Reading, so you *will* have to ship a library of about 3-5MB alongside
your own Binary, if you want to make yourself independent form "potentially not installed PDF-Readers" on a given customers system.
I don't know what you are trying to build there in the end (what is it BTW?) - but it seems to be something "GUI-oriented and big".
From my experience, you cannot build something "GUI-oriented with a whole lot of modern functionality",
without relying on other peoples work (either in form of sources or in form of compiled libraries).
The current practice seems to be:
- to "hide other peoples sources, often without giving them credit" ... accompanied by
- "if it's not possible to gain access to the sources, I will have to hide these dependency-dlls of other people
.. in my own binary, and later drop them onto the users system, hopefully without them noticing).
Well, the obvious (and decent) thing to do is, "to not hide the work of other people, which your solution was built upon" by:
1) giving those other people (in case it was source-code) the credits they deserve in your "deployment-zip" or your "about-screen"
2) shipping the libraries your solution depends on in an openly visible "\Bin\" or "\Dep\" of your deployment-zip (apply rules mentioned in #1 above, here in addition)
Currently you do no such thing (and your *insistence* on "source-only-solutions", because of: "you know, reasons"... sounds a bit suspicious to me).
In the last zipped-up Demo you've posted (for your recent 9-patch-png "solution"), I've not found any sources at all
it was a "code-wise" empty VB-Project, which only referenced a roughly 1MB large OCX (with no source),
which then handed out "just a few fancy rendered Buttons" - not more.
The fact, that LaVolpes Alpha-Image-Project is doing the "heavy lifting" under the covers of your OCX was mentioned nowhere.
(no written credits to his work in your Zip or VB-Project anywhere, and the UserControl- interface of the AlphaImage-Control was not exposed).
I'd strongly suggest to change that current practice of yours in the "final" of your OCX which you ship to end-users.

my language is not english so i hv problem with some descriptions,if u say possible read or write pdf with utf8 support with rc5 so send a sample source code and if u are doing say possible with dz32 post so say a sample code.thanks
and about thread how-can-show-my-png-image-on-form-with-display-blur-effect-under-it-need-user-contro can u send a sample code to can show on desktop layer? i want show outside from form

no way yet ?
Ok, thought that you've searched the Forum for RC5 and PDF-Output already ...
(BTW - you'll get better "hit-results", when you use the [Google Custom Search] field, located in the TopCenter of this Forum-Site).
Here is a link to a CodeBank-article I've posted a while ago:
http://www.vbforums.com/showthread.p...rawingRoutine)
And I've just enhanced that little Demo with a short "Title-Output" (containing Unicode, read from an UTF8-File) - looking like that.

The produced PDF (for what you see in the above PagePreview-ScreenShot + an extra LandScape-Page) can be downloaded here:
http://vbRichClient.com/Downloads/PDFOutput.pdf
If you have questions about the Demo in the CodeBank (in case it's doing "too much already"),
just ask here (or in the CodeBank-thread) - and I will try to provide a simpler example, which does not output as much.

1-when i click on show Pixel- Srf-Preview on the Form i can see just a simple drawing on dc,how can show more than 1 page with scroll bar or better idea ?
2-how can read pdf too by cairo ? my means if i create a pdf (more than 1 page) or if i have been a pdf,can i read and show it with cairo on form?
