Fullscreen Direct3D

I have so far spent six hours trying to find the answer to what I believe is an easy question.

All direct 3D devices are attached to a window. When running in a windowed mode, it is not necessary to specify the BackBuffer's width and height, I presume it gets these details from the window it was created with.

What about when the window is in fullscreen mode? I know to set the BackBuffer, but I'm not very sure exactly what I should do with the window. Looking into the SDK's DXUtil code ( DXUTChangeDevice() ) I can see it sets the window to have no borders, but I cannot see the code change the position or size of the window to match the screen. This goes against everything I know about making a fullscreen window.

Please, could somebody explain how exactly to switch from windowed mode to fullscreen mode at runtime?

Did you find a solution yet?

I'm pretty sure the code that resizes the window is far down in the DXUTChangeDevice().

Look for AdjustWindowRect() and SetWindowPos() Smile | :)

Trust me, I have gone through it line by line. From what I can see, the window is only ever resized and moved when going from fullscreen to windowed mode, but not the other way around. It removes the window borders, stores the WINDOWPLACEMENT and thats about it.

To be honest, I have got so fed up with the sheer size of that file, and it's methods of doing things, that I have completely re-written it ( C++ style ). I have divided it into sections and built a class for each. C'mon, who uses callback's and static window procedures these days?

So, big day tomorrow, the debugging Frown | :(

I see what you mean. Looking at it again, it only does resizing on the windowed-window handle.

I'm not sure why they bother removing the border and menu and stuff Smile | :)

Whatever, isn't the window irrelevent in fullscreen mode anyway? In true fullscreen mode the
device has complete control of the screen, often in an entirely different video mode, right?

Yeah I personally never learn. Every time I use a new SDK I'll get something up and
running, and if I'm using some handy provided base class/sample code, I ALWAYS end up having to
roll my own.

Good luck with the debugging!

Well thats what I thought, especially with something like D3D. But just about every sample I have found moves/ resizes the window and removes the borders. In my opion that is just a fullscreen "illusion".

Access to BIOS alarm registers

I've tried posting this on the hardware forum, but am not getting any replies - So I thought that I would ask here (as it's both a hardware and software problem !!)

Most BIOS allow the automatic power-on time to be set to a particular day and time. However, this is very inflexible as it requires manual intervention to make changes. Some PVR programs have the facility to power on the system at variable times, so I feel that there MUST be a way for a program to access these registers dynamically. Does anyone have any details, or alternatively, point me in the right direction for more information. Thanks in advance for any suggestions !

   If you need to just grab a few items from a small XML stream that has a static definition, you can just load it (i.e. fread(...)) the entire file into memory and just look for the tags of interest using normal string functions.

   If you need to parse and/or validate the XML stream, I would look for an existing XML package.

   I have seen "developers" break out a full DOM implementation of MSXML just to read a three attributes from a 2KB XML file. Complete Overkill to break out COM and Unicode strings for something like that, if you ask me... (And yes, I know that you did not ask me Smile | :)

) Damn thing took longer to load, parse and DOM-ize the XML document than to actually extract the attributes from it!

Peace!

Hello,

double round(double Num, double Seed)<br />
{<br />
    double fac = Num / Seed;<br />
<br />
    fac = (fac < 0) ? (ceil(fac - 0.5)) : (floor(fac + 0.5));<br />
    // fac = (fac < 0) ? static_cast<int>(fac-0.5) : static_cast<int>(fac+0.5);<br />

    return fac * Seed;<br />

round(3.7856, 0.001); = 3.786

Try this method

int nRoundFigure;
nRoundFigure = (int)( 24.58 + 0.5 ); // Answer will be 25
nRoundFigure = (int)( 24.34 + 0.5 ); // Answer will be 24

Hope this will work Smile | :)

How to disable the drag and drop operation in WebBrowser control

Hi,

I am using WebBrowser control to display the HTML help files. My html help files contains some graphics like jpg and png images. When user tries to drag and drop the items from the help pages the WebBrowser control gives debug assertion error. How can I disable this Drag and Drop facility?

I am also setting the RegisterAsDropTarget(VARIENT_FALSE)at runtime after the control in created, but still allowes to cdrag and drop the images.

How can I disable this Drag and Drop facility?

Regards,
Hemant.

   I do not know of any way to do this... If you can get notification of the D&D operation, you may be able to inhibit it, but I am not sure if the WB control gives you that information (easily, if at all).

   It might be worth finding out why you are getting the assert, and solving that problem.

   Peace!
