A very urgent problem

Hi!

Now I wanna sent 4 bytes data by calling DeviceIoControl() from my directshow application to my streaming minidriver.First,I call the CreateFile() to get a device handle,and the minidriver can receive a IRP_MJ_CREATE IRP,and the CreateFile() returns nonzero.But when the app runs to DeviceIoControl(),the minidriver does not recieve any SRB.The DeviveIoControl() returns zero,and GetlastError() returns 50,which says:"The request is not supposed."
I difined my own IOCTL command in my driver and app.
What causes the error 50 or if there is any other way to send data to steaming minidriver from directshow application?
Thanks for any help! Smile | :)

Does CreateFile return INVALID_HANDLE_VALUE?

Does your driver antry set a dispatch handler for DeviceIoControl?

Does you DeviceIoControl handler handle that IOCTL?

Is the buffer size correct for thst IOCTL?

Netgear WGR614v6

Douglas Troy19-Sep-05 5:30

About 3 months ago, I purchased a Netgear WGR614v6 Wireless G router; and have had nothing but problems. Depsite my continued posts on Netgear's site, and unanswered calls to their Tech Support, I thought I would post my woes here, in hopes someone might have a suggestion for me that I've yet to try (other than purchase a LinkSys router - which is what I should have done from the get go).

Here's the problem:
Anytime any computer connected to the router via wireless, attempts to copy a large number of files (to a Local share on the main PC to which the router is directly connected), the wireless on the router just dies. All the hard wired computers plugged directly into the router still have a connection, it's just the wireless that essentially "turns off". The only solution is to unplug the router and plug it back in, thereby "restarting" the router.

What I've tired (settings)
Originally I had the router set to Chanl. 11 with 64-bit WEP enabled. After a post to the Netgear fourms with this problem, their tech support suggested I switch to Chanl 1 and disable WEP.

Well, since I'm not about to run a wireless router without security, I changed to Chanl 1 and switched over to WPA encryption - still the same problem.

I can copy "smaller" files back-and-forth all day long, but if I attempt to copy a large number of files (e.g., 5+ gigs) - it will kill the wireless connection almost every single time.

Suggestions? (before I go out and purchase a LinkSys router)

That sounds like a physical problem with the router. I am trying to track down a similar problem with the same model v4 system. The router, however, never locks up -- I have been trying to establish if it is db strength or external influence or something internal. When transferring large files communication will be lost in the middle, unknown reason, but there is no need to reset the router, all physical functionality is maintained following the interrupt. I can start again easily within about 10 seconds without reset. However, it still kills the copy. I'll have to check here for answers in case they are related. Or we both toss our Netgear systems and go linksys.

If the unit is still under warrenty coverage I would hassle them about it, you paid for it, a locked up router should be their fault. Mine has never locked up, it runs unattented at the top of my bookshelf.

I have been bugging them about since day one, and they keep telling me that it must be some form of interference from another device ... blaa blaa blaa ... but I can lock the router up every time, just by copying a large number of files.

I am actually going to BestBuy to purchase a LinkSys router today; I will let you know what happens with that one ... although I suspect it will work just fine.

I am no networking genius... but I would think that mine "could be" interferance, the router stays working, all the hardware is working after the "cut off". Interference from another device should interrupt the signal, but leave the hardware functioning, just like mine. But yours is locking up the router, that sounds like hardware.

Well, I purchased a LinkSys Wireless G router lastnight and set it up using the same "defaults" that I had the Netgear router configured under. After several hours use, and copying large numbers of files back<->forth from my server to various PCs (wired and wireless) not a single glitch.

So ... having done that, and said that, a call to Netgear is in order ...

Nothing like owning a $30 wireless paperweight ... Dead | X|

You can tell them they lost two customers.... I guess this is my next purchase too.

Re: Caller ID Application

30-Sep-05 10:59

Well, I went more bizarre in my solution.... The machine I do the longest copies from is my DVR on a wifi ethernet bridge... so I am picking up a pair of electric outlet bridges to see if I can manage 1/3 megabit through the walls... they claim it will do 11 megabit, most reviews say 6 realistically, that's all still more than I need.

and surprise... LinkSys, bypass the wifi for anything other than handheld and work laptops which so far have not been a problem. Maybe swap the wifi out come tax season.

How to detect LPT port base address?

You don't need to detect the base addresses because the pnp manager should do this for you.
Enumerating LPT ports works via setupapi.

Real hardware

This is a real hardware question Wink | ;)

. I'm going to build something of an old C64 computer, I only want to take the processor, and as few components as possible.
I'm going to do a hardware that displays time in binary. I'll need the ROM to, or at least another ROM, the program I want to write is like this in assembly:

org	100h
	xor	cx,cx
	xor	dx,dx

start:
	inc	eax
	cmp	eax,07FFFFFh ;clockspeed in hz
	je	sec
	jmp	start
sec:
	xor	eax,eax
	inc	bl

	push	dx
	push	ax

	mov	ch,bl
	call	printANuminCHwithSpace

	mov	ch,cl
	call	printANuminCHwithSpace

	mov	ch,dl
	call	printANuminCH

	MOV	dl, 13	     ; print char
	MOV	ah, 02h
	INT	21h

	MOV	dl, 10	     ; print char
	MOV	ah, 02h
	INT	21h

	pop	ax
	pop	dx


	cmp	bl,60
	je	min
	jmp	start
min:
	xor	bl,bl
	inc	cl
	cmp	cl,60
	je	h
	jmp	start
h:
	xor	cl,cl
	inc	dl
	cmp	dl,24
	je	day
	jmp	start

day:
	xor	dl,dl
	jmp	start


printANuminCH:
	push	ax
	push	dx

	xor	ax, ax
	mov	al, ch	      ;2 char
	mov	dh, 100      ;1 char  skipping this for now
	div	dh

	add	al, 30h
	MOV	dl, al	     ; print char
	MOV	ah, 02h
	INT	21h

	xor	ax, ax
	mov	al, ch	      ;2 char
	mov	dh, 100
	div	dh
	mov	al,ah
	xor	ah,ah
	mov	dh,10
	div	dh

	add	al, 30h
	MOV	dl, al	      ; print char
	MOV	ah, 02h
	INT	21h

	xor	ax, ax
	mov	al, ch	      ;last char
	mov	dh, 10
	div	dh

	add	ah, 30h
	MOV	dl, ah	     ; print char
	MOV	ah, 02h
	INT	21h

	pop	dx
	pop	ax

	ret

printANuminCHwithSpace:
	push	dx
	push	ax

	call	printANuminCH

	MOV	dl, 20h       ; print char
	MOV	ah, 02h
	INT	21h

	pop	ax
	pop	dx

	ret

The displaying code isn't going to be there.
Here's how it could look like when implemented:

The ports should be replaced and represented by their appropriate value.

org	100h
	xor	cx,cx
	xor	dx,dx

start:
	inc	ax
	cmp	ax,0FFFFh ;clockspeed in hz
	je	sec
	jmp	start
sec:
	xor	ax,ax
	inc	bl
        out     bl,0h
	cmp	bl,60
	je	min
	jmp	start
min:
	xor	bl,bl
	inc	cl
        out     cl,1h
	cmp	cl,60
	je	h
	jmp	start
h:
	xor	cl,cl
	inc	dl
        out     dl,2h
	cmp	dl,24
	je	day
	jmp	start

day:
	xor	dl,dl
	jmp	start

Is there any good company, (europe should be best, I live in Sweden), that makes ROMs? How much could it cost. I don't want to use to much money.

I need 17 outputs, do I need a multiplexer? Where could I get one?

How is the machine code in the C64?

Thanks in advance
