Windows DDK Print Sample Code

Hello, guys.

I must be doing something stupid or the tool (VC++ 6.0) I am using may not be the right one..

I need to build a "virtual printer driver". I am quite new on this area of developing, and many recommanded I'd better study the DDK print sample source code first and read some DDK documentation. I found the DDK documentation is not helping me understanding much on the subject.. so I tried the sample source code ( /genprint and /oemdll )

I am using Visual C++ 6.0, which I don't use everyday.
I thought I needed to create a project, so I chose Win32 DLL project with "empty DLL project" option. Next, I added the source files into the project, including the DDK and SDK paths in "Options".

When I tried to build - just for the heck of it - , what I got is a bunch of errors:
- 'struct' type redefinition
- 'try' & 'except': undeclared identifier
and even syntax errors...

The html files (about how to build) in the same directory are useless.

Could you be kindly enough to explain or give some instructions about how to build those sample source code from DDK print with VC++ 6.0??

Confused and frustrated

Check out http://www.codeguru.com/system/KbdClass.shtml ("Using the Visual Studio 6.0 Driver Build Environment "), this will explain what you have to do.

try to open the sources.inc and then make the same setting under VC's IDE.

hi, BeyondWu. how are you doing?
I took a look at the sources or sources.inc files, however, my knowledge on VC++ IDE is rusty and honestly, I am not sure I understand what I am looking at in those files, which means not sure what to do next on setting the VC++ IDE environment. (I just started studying the jkr's articles..)

Could you elaborate your comment on how to set the VC++'s IDE.. I mean where(under which menu/what dialogbox) should I make the change, if necessary?? (I hope I don't take too much time of yours..)

Thank you, guys..

Device driver authoring is hardly a place to start your VC++ experience!  Once you have a few standard applications under your belt, then try writing a few DLL projects and and a test-harness EXE for testing purposes.  Once you have a firm grasp on how to use the IDE, the information in jkr's link will make a lot of sense and will solve your problem.

In the mean time, you can use VC++ as the editr and just use the command-line build batch files that come with the DDK.

I wonder about all of these recnet "virtual printer driver" questions.  Did somebody put a fat fee on Rent-a-Coder or something?

Thank you for your comment, DanRollins. I appreciate any input. Yes, what you are suggesting is the proper steps toward any application development project. But sometimes fortuna(goddess of luck) just passes by, leaving us doing without reasonable resources or assistance, which is my case at the moment.
So could you generously elaborate what those are the command-line build batch files and how to use them?? please don't roll your eyes.., and imagine that you today walk someone home safely..

Thanks and have a good evening, guys.

I've only messed around in the driver area once or twice.  I downloaded the project and there was a build.bat file in with the other files.  I recall having to execute the one of the setenv batch files also.

So, is this a Rent-a-coder project?  Curiosity overcomes me.

Thank you, DanRollins.
First off, this is not a Rent-a-coder project, it's one of internal projects from our company.
Could you tell me where you downloaded the project you mentioned??

For what it's worth, I download the RAMDISK.SYS device driver source code.  

I presume that there are other examples that are more relevant to your problem.  One other thing, I havd to make sure that the the default directory was the the one with the source code before running the MAKE utility.

sorry for my later response.
I use the "oemuni" sample under ddk folder, please follow me;)
1. Create a New "Win32 Dynamic-Link Library "project.
2. Input a name(any string) into the "Project Name" edit box.
3. Press [OK], then select "a simple dll project", I think you also can select "an empty dll project", but I've tested it.
4. press [finish].
5. delete all files from the left project window.
6. copy all files from the "oemuni" subfolder into current project folder.
7. add all files into current project.(I assume you know how to do it).
8. open source.inc file.
9. if there is a line "PRECOMPILED_CXX=1", it means using precompile head.
10. select "xxx files" from the left workspace window.
11. press right button of mouse, in the popup menu, select "settings..." item.
12.select "C/C++" tab.
13.select "Precompiled Headers" from the "Category" comobox.
14.select "Use Precompiled Header file (.pch)". then input "precomp.h" in the "through header:" edit box.
15.press [OK].
16.from the sources.inc, there is a line:
so open the setting dialogbox again(refer item 10), then select "C/C++" tab, and select General from "Category" comobox, in the "Preprocessor definitions:" edit box, input all the symbol copy from the sources.inc.
the USERMODE_DRIVER comes from the file "sources" under the umode subfolder.
17.still in the "C/C++" tab, select the "Preprocessor" from the "Category" comobox, input your ddk's include dir into the "Aditional include directories:" edit box.
for me, it is "F:\WINDDK\inc"
18.there is a line "DLLBASE=0x70000000", so you need to open the setting dialogbox again, select "Link" tab. then select "Output" from the "Category" comobox, input the "0x70000000" into the "Base Address:" editbox.
19.there is also a def in the umode folder. so please add this file into your project.
20.for this sample, the "precomp.h" file is a precompiled header file, but for VC's IDE we need a .cpp to use it.
so please create a new .cpp file and insert the line "#include "precomp.h" into the cpp file, then add this cpp file into your project, then select the cpp file in the left workspce window, press right button, in the popup menu, select "setting..." item, select "Precompiled Headers:" from the "catagory" comobox, then select the "Create precompiled header ...", then input the "precomp.h" into the following "Through header" edit box.

OK, that's all.:) hope this help you.

Dear BeyondWu,

I am so impressed with your step-by-step instructions. I have to tell you that it is so hard to experience this kind of generosity these days. I really appreciate it. You will definitely get my points.

I have one last question for you, if I may. The program was built successfully and I got the dll now. And I am not sure what to do with this dll. I think I am supposed to use the dll to add a printer. Can I simply use the oemdll.inf??

And forgive me quoting this poem:
Expect nothing.
Live frugally on surprise. – Alice Walker

Thank you for the pleasant surprise.
Good day, BeyondWu.

Dear alexzen,

For the samples of ddk, there is always a corresponding .htm file to indicate how to install it, yea, for this sample, you can use the oemdll.inf to install it. please refer "INF File Sections and Directives" for more details of .inf file. I recommend you first study the section "Display and Print Device" at least, before you begin to code for your Printer Driver. You also need to know how to debug it, I'd like to use SoftIce...

Good day, and you are welcome.

Dear Sir:

I have a similar situation. I tried to compile the sample source from the ddk just by the command of "build -cz" . I got a error like this:

precomp.obj() : error; intenal error during Pass 2.

Can any friend tell me what is wrong in my work? What i did is just use the original source code. Should i change something in the source code?

Thanks in advence
