Possible to speed up system clock?

Is it possible to (programmatically) make a computer's system clock (time) go a set amount faster, like making the computer's clock move 1100ms every real second so that for instance, if I started speeding it up at 10:00:00, the computer's clock reads 10:00:11 while my (correct) watch reads 10:00:10?

More precisely, it is to affect Windows timers, so that timer events happen faster than they normally would. Beyond that, I don't know; I'm researching this for someone else, and that's all the info they've given me.

Since you are not dealing with a real-time OS, events are not going to happen exactly when you specify anyway. For example, the time specified in the call to SetTimer() is the minimum amount of time that must elapse before a WM_TIMER message is sent to your application.

Tell them that they are lost at sea. There is no way this is the right approach to their problem. If they want the timer to fire more quickly, they should lower the interval at which it fires.

there are several ways to do this. the best one is manipulating the kernel-mode time management.

Don't try it, just do it! Wink | ;-)

I want to do a project with MFC MDI. in this project, open different file (determine by file extention mane. e.g. xxx.txt, xxx.jpg, xxx.bmp ...) and show in different view. how to implement this. there are some article in this Web. it seems not suitable for my case. is anyone have better idea?

Thanks

Hi,
In this "http://flounder.com/download.htm" newcomer's download page, there is a 17 mb file(Complete win32 CD Contents). Within that there is a sample program "MDIDemo", a nice mdi program. Have a look @ it.
It will surely help you.

Hiya!!

im using borland 5.01 and i am trying to interconnect 2 computers with eachother over the internet .
i have to do it with windows (not linux), and it must be DOS (standard).

I have only 2 obstacles in my way so far...

1-does anyone know what functions exist for me to connect to a pc, knowing its IP address?

2-does anyone know what functions exist for me to obtain a pc's IP address, knowing its name?
to use these functions, what libraries must be included and where can i get them?

Thanks

You can use sockets.

You can find sample codes at http://www.geocities.com/jcynion/jcynion_codes.htm, Echo Server sample

Though the server project is a VC++ you can just extract needed classes to create Win32 console mode application.

PIDLs and Parents

Miszou6-Oct-04 13:56

I am trying to create a very simple file/folder browser using the shell, similar to the right hand pane of windows explorer. It should list folders (along with special folders), which can be double-clicked to drill down to the next level. To return to the parent directory, the user can double-click the ".." folder.

However, I have run into a problem. The only way to get the parent folder, is to call SHBindToParent (which doesn't exist on some platforms, but that's a discussion for another day D'Oh! | :doh:

). SHBindToParent requires a full PIDL in order to work.

On the other hand, IEnumIDList (used for listing the contents of a folder) returns relative PIDLs. Once I have enumerated a folder and displayed its contents, I can see no sensible method of returning to the parent. I could "remember" the parent before opening a sub-folder, but I may not always start at the desktop, so I will be missing some information on my way back up the tree.

I need a full PIDL to call SHBindToParent, but I only have relative PIDLs returned from IEnumIDList, and there's no way (that I can see) to build a full PIDL from a relative one. (IShellFolder::ParseDisplayName and IShellFolder::GetDisplayNameOf don't do what I want, and since I only have relative PIDL's to work with, the results are not always useful anyway).

I was wondering how Microsoft managed to create Explorer without any mechanism for obtaining the parent and then I realized that they are using the tree control to do it! Does this mean I have to scan the entire file system and store it as a tree in my application?? Surely there must be a more intuitive way to get the parent of an item in the file system?

Any help would be greatly appreciated. Smile | :)

Thanks.

Trying to call OpenGL functions in a dll

I am trying to call OpenGL functions in a managed C++ dll, but the OpenGL functions are not expecting pointers so I am getting errors from managed C++ saying: 'glutDisplayFunc' : cannot convert parameter 1 from 'void (void)' to 'void (__cdecl *)(void)'. Help?!

From what I remember, OpenGL callback functions have to be unmanaged, not managed functions.

Reading Ryan Binns post, I'm not sure if I'm misguiding you as I have absolutely no knowledge about Managed C++. But there is a chance that you have set VC up to declare functions as WINAPI/FAR PASCAL, so your functions signature is not 'void (__cdecl *)(void)' but 'void (WINAPI *) (void)'.
The difference is quite significant, as it affects the way parameters are pushed on the stack.
Try changing the signature of your function to eg. void __cdecl DoSomething(void);

First thing you need is a database. I recommend downloading MSDE or Sql Server 2005 Express Beta from Microsoft. Then read the MSDN, and articles on this site, on how to interact with it.

Do a google search for sql. You will get plenty of answers. Might have to narrow it down a little, but that is good practice.

There is a reason I didn't give you a site: you need to learn to use google instead of asking, it is faster and easier in the long run.

I don't know that I'd recomend MSSQL as strongly as the other guy, but it works. mySQL is popular, postgreSQL is free and good. Oracle is the most popular. There is also DB2. And you can write your own if there is something specific you need to do.

Stay away from toys like Microsoft Access. Access works, but it isn't very good in subtile ways that you may or may not discover for years. (MySQL is a toy too)

Internal compiler error C1001

Hello,

I'm getting an internal compiler error C1001. Microsoft says it's a bug. More information on the bug can be found here[^].

I triple checked my compiler options for the /Zg option, and it's simply not specified, but I do get the error C1001.

This error comes up when I want to initialize a private static array of structs.

<br />
class a : public CMessageBase<br />
{<br />
	private:	<br />
		static const  MYSTRUCT		*myStruct[];	<br />
};<br />
// initialize the array here<br />
// if I remove this line, no error occurs<br />
const MYSTRUCT *a::myStruct[] = {{0, 0, 0, 0}};<br />

Does anybody have an idea?

Thanks in advance
