I want to transfer a block of data from one memory location to another using DMA. Is it possible to directly make a DMA call from my VC++ application code or do I need to go to the driver level for this.

Thank You. My further query is that in my application code, the two memory buffers i.e the source buffer and destination buffer have some virtual addresses. To do DMA, I need the physical address of these buffers. How do I map virtual address to the physical address to initiate DMA?

To programatically do that, check out these registry functions[^]

You can create another application with a timer implemented to launch your program every 2 hours.

Well, that's slightly different than just running at startup.
For periodic scheduling, you will want to use the "Scheduled Tasks" in Control Panel.
Go to Control Panel, start scheduled tasks, add your application as a task, select to run it when your computer starts, Enter the credentials you want it to run as, choose "Open Advanced Properties for this task when I click finish", click the "Schedule" tab, check "Show Multiple schedules", click "New", click "Advanced", check "Repeat Task", and configure it for every X minutes, etc...
Hope that helps.

I'm not sure if I'm answering your question. I guess you might want what Weiye Chen suggested and create an application that uses a timer to run something every 2 hours.
To start this first app, put the path in the registry key mentioned earlier. you can set this key using your .msi or whatever installation technique you use when distributing you apps.
Good day.

Your static control cannot have the id IDC_STATIC. Change that to whatever other value.

In the CDC class there is a GetTextExtent() metod you can use. To get the dc: CClientDC dc(this); and then dc.GetTextExtent(..)

Hi all,
i'm doing some test with VS2005 and I'm wondering if there's any control or view that permits to create a dialog with the look and feel like the windows explorer. I mean the left side blue menu that it's like (or it's) DHTML. I don't know if the only way to do that is with the CHtmlView / CHtmlCtrl but maybe the .Net has a control to do that.
Best,
Marc Soleda

Driver development is complex and totally different to writing a user mode application. I suggest you get a good text book and start reading.

Could someone tell me how to write a method overloading?
Thanks
Moujan

Here's an example:
void SetRect(CRect& rect);<br />
void SetRect(int top, int left, int bottom, int right);<br />
Adding this:
void SetRect(int top, int left, int width, int height);<br />
would be invalid, because a method with (int, int, int, int) already exists above.
Does that help at all?
