yes i did and tried OLE automation. But it didn't help me. Someone in Adobe Forum responsed my question of " why I can't call functions of Adobe Acrobat Classes? ", as Adobe Acrobat doesn't not support OLE yet.

But I found how to print pdf file using commandlines. Those command lines are:
Acrobat.exe /t filenameWithpath printername drivername portname
what this command line does is :
1) initiates Acroat
2) print a file
3) then terminates Acrobat

first 2 steps done perfectly but step 3) closing Acrobat never happened.
don't know why.

I was so happy when I found out this command because all steps are exacatly what I want. open, print, and close. But closing doesn't work with this command as it is stated in "Acrobat Developer FAQ Document".

Do you know how?

Thanks

It depends on what DirectX graphics module you are using.

Are you using Direct3D? Then, the interface ID3DX has several functions to load BMP, PNG, and JPG (but not GIF) as 3D textures. These textures can then be rendered in a 2D mode by using D3DXSprite. (If you do search engine requests on these terms, you could probably use the bulk of other people's code to try it out.)

If you're using DirectDraw, then you're on your own in terms of finding functions to decompress graphics files. I suggest looking into the FreeImage library. (Go to www.6ixsoft.com for more info.)

Sure. Just make sure to export your functions with _stdcall
This is the way how I did it

This is how your exported functions in the DLL look like:

extern "C" __declspec(dllexport) void _stdcall YourFunction()
{
	// TODO: insert your code here
}

To make importing from Delphi easier it is recommended to change the function declaration in your .def-file like this:

; yourdll.def

LIBRARY      "yourdll.dll"

EXPORTS
	YourFunction=_YourFunction@0

This way you can simply import your function on delphi side by importing the function "YourFunction"

Well,I use this in cpp file:

extern "C" __declspec(dllexport) STDMETHODIMP _stdcall  CSecurity::IsAdmin(BOOL* bAdmin)

But I got this error:
error C2375: 'CSecurity::IsAdmin' : redefinition; different linkage

I think I have to change some project setting?

Hi. I've been working on these examples even after I unfortunately lost, my CD with source code provided with Petzold's book "Programming Windows" (version about 98 and NT). But now I'm stuck, and I desperately need the source code, to compare it with mine.
So, does anyone know where can I download it (for this version of book, not for Windows 1.0 or Windows 95), or if can someone send me only the source code (without executables), or even only, source code for 21th chapter.
Thanks.

Thanks for effort, but this is not what I need (since this is not what I need, and I noticed Jeffrey Ritchie in the commnet, I assume that this is not even from the book, which rource code I need).

Again, Im desperatly need this source code, can anyone help me with this??

"token" in strtok - a very simple question

ns22-Sep-02 2:27

22-Sep-02 2:27

THe dictionary doesnt give a technical definition, and its not clear to me what a token is from MSDN, in strtok. Say I have a string

abc_defg_hi, and I want to break it up into abc, defg, hi etc. THe delimiter is '_', and if do strtok on this string one time, what do I get back?

Sorry if this sounds too simple, but I am really not sure what exactly the token is, in this case.

Thanks,
ns

pointer to "abc" first time, pointer to "defg" next time, then pointer to "hi" and NULL the last time.

Token is a part of the string delimitted by the delimitter in this context.

How do I strip \r\n from a CString?

I wonder what is an elegant way to do this? I just need to split everything that's after an optional \r (no matter if there is more text behind it). Thanks!

<br />
CString string, result;<br />
char* temp;<br />
char* token;<br />
strcpy(temp, string);<br />
token = strtok(temp, "\r");<br />
result = token;<br />

Probably not the most elegant way to do it but it works. Later.

Well. You will have to walk through the CString object and split the sections. Use the Find() and Mid() function for the CString object.
