Re: How to shut off Floppy's LED rapidly

Are you asking if you can terminate a read operation when it is half-finished?

If so, you can use overlapped I/O and use CancelIo() to cancel it before it completes.

Why do you need to do this? It's not very common reading from files; more common reading from serial ports and "slow" devices.

The LED dosn't shut off immediately
At last I change my codes in my loop partition like:
while(true)
{
Sleep(3500);
m_hFloppyDisk = CreateFile(TEXT("A:"),
0,
0,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL);
}

The result is that LED can go out after about every four seconds' being on
which seems like blinking to some extend.
Not very like.

You can't make the LED stay on longer or shorter. The timeout is set to 2 seconds by default in hardware, and the only way you can change it is to reprogram the floppy drive controller. Windows does not support this, so there's no way you can do it, short of writing a new floppy disk driver.

MFC Question

I've created a new dialog menu box and one drop-down menu item. I want to enter text information into the program which will appear in a new screen when the user clicks the menu item I just created(I hope I said that clearly). My questions:

1. Should I create a Document class to accomplish this?

2. I noticed that VC++ 6.0 gives the option to create different types of documents(Power point, access, Word, etc.). I am a bit confused on this. Is the how to enter text into my new document class, by entering info into a Word document? What is the standard way that programmers enter the text and pictures into their document class?

that depends on how and where the text is entered...
Do you enter text in the already existing dialog or do you enter the text in the new window?

I could be wrong, but I thing that the standard way for storing text into a CDocument class is just to derive your own. That way you have a class that fits whatever you need.

I'm wanting to do exactly what you said, but how do I go about it. I want to create my own text (or copy/paste in text from other documents I've typed out). Thanks.

If you want to create your own text you can derive your class from CView and implement the OnChar method. Then display the character...

The other thing you can do is use a CRichEditView,... You can find everything you need in the msdn library. Smile | :)

Good luck

how to generate GUID programatically in VC6

I want to generate GUID for my objects inside my application without the need of using external GUIDGEN utility.

Re: how to generate GUID programatically in VC6

Use the function

HRESULT CoCreateGuid(
  GUID  *pguid  //Pointer to the GUID on return
);

Hope that helps Big Grin | :-D

-Dominik

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Need help with program

I have two questions:

First, I'm trying to get the following program to work. I keep getting an error message that the "DDRAW.LIB" include file cannot be found. I did go into TOOLS/OPTIONS to specify the WINDOWS/SYSTEM directory where the Ddraw.dll is located. What am I doing wrong? The compiler still can't find DDRAW.LIB.

Second, I can see in the program below that there are definitions that need to go into a header file, but I'm not sure what to place in the header file. COuld someone please help me out with this? Thanks much, Dave

Hello,

The .lib file is not located in the windows\system\ dir. the dll you want to use is located there... Confused | :confused:

already

...

I don't know if I'm sure, but the .lib file is used by the compiler. the dll by the program.

In the VC++ directory you should find the "lib" dir. DDraw.bib is located there!

for the header file:
I'm sure on this part Smile | :)

. All your definitions, prototype declarations (headers Smile | :)

) and macro's should be there. The implamentation shoud be in the implementation file (*.cpp).

hope this helps.

Thanks Bob,

For some reason my compiler is saying that it cannot find the Ddraw.lib "include" file. The file is located in the MFC directory of my Visual Studio, but my compiler doesn't see it even though I have set the directory to it in TOOLS/OPTIONS. Hmmmm

Thanks Much, Dave

1. The more code you post, the less likely you are to get a reply. You can't expect someone to read through that much code.

2. Any definitions that you want to use in more than source one file should be in a header file.

3. You need to specify the path to ddraw.lib, not ddraw.dll. And it's not an include file. It's a library file.

Hope this helps,

Ryan

Will do Ryan, Thanks. I only posted the code in hopes that someone would draw a line between what should be in a header file and what should not. I agree with you.

It's called the Graphics and Multimedia Services SDK. But it seems to be available only as part of the Core SDK. Get it from the SDK Update[^] center.

I need to create more than one text box with the same name(this call array),with the code;
for i = 1 to CInt(request.Form("quantity"))
count = count + 1

serial_field = "serial"&count

end loop

then, when I need to check whether user already fill in this text box, I can not access that text box name.Text box name suppose to be serial1, serial2 and so on.I am using this code;

for (a=o;a<=30;a++){
if (document.Reg.element.serial[a].value == "") {
err = true;
msgstring = "Fill in serial number";
}
}

I can access the value only if I directly use the name like;

if (document.Reg.element.serial1.value == "") {
err = true;
msgstring = "Fill in serial number";
}

Any suggestion what I should do to solve this problem. I am sorry my explanation is quite massy.

Thanks

I wish I could help you but I don't know Javascripts. On the other hand, this is a C++ forum, so your question might not find an answer here. Please don't get offended by this. Smile | :)
