Hi all,
I was reviewing the SDK for printing. I used the provided examples and created some simple tests to do some more learning.
The attached coding is what I currently have. The coding runs everything just fine up to the OpenPrinter statement, then it fails with invalid printer name, even thou I verified via a messagebox it is there and correct just before the OpenPrinter statement. Not sure what to do, any thoughts.
Also, how do I convert the OOC format Graphics* graphics statement to asm format and its associated methods.
Thanks
Steve
I can't see any problem with your code, but my test app running under Window 2000 works OK.

Sir Michael,
I cut and pasted your example code and did all the normal compile stuff. Everything worked as defined. OS = XP SP2.
I am still testing what I have just to make sure I am on the right path and to understand what I am doing wrong.
Thanks Steve
Hi MichaelW:
When I run the progran we get a message winspool.dll was not found and re-install may fix
this problem.
I have a winspool.drv and a winspool.exe in c:\windows\system32
04/14/2008 05:42 AM 146,432 winspool.drv
08/04/2004 07:00 AM 2,112 winspool.exe
2 File(s) 148,544 bytes
0 Dir(s) 119,351,197,696 bytes free

Micheal and Herge,
I found two issues:
First memory allocation is working (ie allocated) but for some reason random data was showing up in-between commands within the allocated area itself. Still not sure why. I then used a Local variable and defined it as a 256 byte array and referred to this versus the allocated area. This took care of this issued, although I still need to go back and find out why data is showing up randomly in an allocated area.
Second, I also expanded some useage of the Win Spooler (added and used more functions). After tracing thru a couple or errors, I found out that I have about 50 different versions through-out my system (different Dos dates). The one I used with my app below was at least 10 versions back, so I referred my coding to use the one within the Windows directory and retested. Every thing worked fine.
I have learned to added coding to check for version control during setup of my apps, to avoid this issue. Others should also take note.
Thanks
Steve

I think all OS's considered NT variant, have .dll version. In my PrintRTF code I use the following for use with 9x OS's an beyond...
.data
szWinSpoolDRV DB "Winspool.drv", 0
szWinSpoolDLL DB "Winspool.dll", 0
szOpenPrinterA db 'OpenPrinterA', 0
.code
invoke LoadLibrary, offset szWinSpoolDLL ;NT
or eax, eax
jnz @F
invoke LoadLibrary, offset szWinSpoolDRV ;Win9x
@@: mov hSpoolLib, eax
invoke GetProcAddress, hSpoolLib, offset szOpenPrinterA
...hth,
farrier
Thanks Farrier, I like the dual OS capability and will convert / insert this method into my coding also. Steve
