Hi!
I've created a single dialog based application in which i am using
flexgrid control.I am using textbox in the cell of flexgrid for writing.
the textbox in the cell is the object of class "MyEdit" which extends CEdit.
I've trapped the enter key pressed in the textbox.
Now I want to tell the dialog box class when enter key pressed in textbox which is the
object of class "MyEdit" so that the dialog class moves the textbox in next cell same
thing as we do in excel.
Thanks in Advance!

What is the use of the function SystemTimeToFileTime?
Why should we convert a SystemTime to Filetime?
What for it is used?
|
|
|
|
|
A FILETIME is easier to serialize than a SYSTEMTIME struct. FILETIMEs are a lot easier to compare too.
|
|
|
|
|
First your user name is very sweet.
The basic use of SystemTimeToFileTime function is to just convert the current system time to the file time i.e
File time is the time related to some specific file i.e the creation time, the Last Access time etc..
you can get more help of the file timing in MSDN in follwoing articles:
1. GetFileTime
2. FILETIME
3. SYSTEMTIME
if you still have any doubt about this pls feel free to ask

In a game i'm making, i have a projectile which moves in a direction for a limited distance. What i want to do is create the projectile dynamicaly, and then have it control itslef, rather than adding in extra code to check if there is a projectile, how many there are, and then move them all.
Now, if this where C#, i'd just create a new thread for the method. But im not sure what to do here.

You can create threads in C++. Remember that adding a thread won't make your code any faster.

Of course not, its still the same amount of logic. But it is more convenient.
I'll go look up threading in c++ then.

do you need thread help in c++??
|

No i found out about it, much easier than i thought actually 
But anyway, it didn't go so well, since i realised the only time the thread could draw the objects, was before everything else. Meaning it would be behind everything, and if there was a background, you wouldn't see it at all. In the end i just made a new class with functions to add / remove the objects and control them. So quite a bit more code. Although it only added 3 lines to the main loop. Projectile.Add(), Projectile.Move() and Projectile.Draw()

Hello Jason Henderson !
I have seen your article :"WallpaperQ :A Wallpaper Management Tool " .I wrote a program by Win32(in VC++6).My simple program include: a button "OK" and a button "Exit"(in dialog "Test Wallpaper").In button "OK",i wrote code as follows :
//at WM_INITDIALOG event
pIActiveDesktop = NULL;
HRESULT hr = CoCreateInstance(CLSID_ActiveDesktop,
NULL, CLSCTX_INPROC_SERVER, IID_IActiveDesktop,
(void**) &pIActiveDesktop);
if (FAILED(hr)) pIActiveDesktop = NULL;
//in button "OK"
if(pIActiveDesktop == NULL)
{.......
SystemParametersInfo(...,"image.bmp",..);
.......
}
else
{..............
pIActiveDesktop->SetDesktopItemOptions
(&compOptions, 0);
............
pIActiveDesktop->SetWallpaperOptions
(&wpOptions, 0);
// Set the wallpaper image.
pIActiveDesktop->SetWallpaper(T2CW
("image.jpg") , 0);
// Apply all changes.
pIActiveDesktop->ApplyChanges(AD_APPLY_ALL);
}
My program only run the first case(pIActiveDesktop=NULL)(i.e it only set to Desktop Wallpapers ".bmp").I (very)want to try the second case but not succeed (i hide the first case,when i click "OK", a error occur"memory can't read ").
Please help me how to "IActiveDesktop is available"
Thanks !

I have no knowledge in openGL, can anyone tell me how to write a getpixel function?

I've got a problem with a C++ class template representing a matrix object. The template parameter will be one of a number of things - a double, complex<double>, or a vector<double>, all of which have the * operator overloaded so that they can be multiplied by both themselves and a double.
My code at the moment is:
<code>
template < class T >
Matrix<T> Matrix<T>::operator*(const T val)
{
int ne=NumEl();
Matrix<T> tmp(Rows(), Cols());
for(int i=0; i< ne; i++)
{
tmp[i]=dat[i]*val;
}
return tmp;
}
template < class T >
Matrix<T> Matrix<T>::operator*(const double val)
{
int ne=NumEl();
Matrix<T> tmp(Rows(), Cols());
for(int i=0; i< ne; i++)
{
tmp[i]=dat[i]*val;
}
return tmp;
}
</code>
This won't compile when I declare a Matrix <double>, since the first function implementation with T=double is identical to the second one. Any ideas on how I can fix this?
I'm using gcc version 4.1.2 20060928, if that makes a difference.
Cheers
-Chris

I remember researching a similar question a while back, and there is no solution. What you're asking for is a template operator* that only works with certain types (or more precisely, doesn't work on certain types), and C++ doesn't let you do that. You can't restrict template type parameters like you can in C#.
|
|
|
|

Why do you need to have a different declaration in that case?
If the code is just an example:
One way would be to specialize Matrix<T> for doubles, to include only one of the "operator*":
<br />
template<><br />
struct Matrix<double><br />
{<br />
Matrix<double> operator*(const double v) { ... }<br />
};<br />
But that might involve lot of typing for a full-fledged matrix class. You might move all implementations to distinctly-named base class functions, but that helps only so much.
Another option (but with slightly different semantics) is to make the first operator weaker by making it a template:
<br />
template <typename T><br />
struct Matrix<br />
{<br />
template <typename T2><br />
Matrix<T> operator*(const T2 v) { ... }<br />
<br />
Matrix<T> operator*(const double v) { ... }<br />
};<br />

Thanks for your help - the second bit of code looks like what I want to do.
