see here[DirectXSetupGetVersion^], winxp shipped with default directx 8.1, while windows XP SP2 updates to directx 9c. See the API DirectXSetupGetVersion which gets the version of directx currently installed in the system, if that matched or higher you can run your application or install programmatically or ask user to install the required directx version runtime.
[Added]
And DirectX SDK has samples demonstating these (1 )DXInstall(DXInstall is an example of how to use DirectXSetup interfaces to install the DirectX subsystem and DirectX drivers) (2) GetDXVer (to get the version of directx installed)

Hi all,
I am trying to convert a API that's used in a MFC app, i want to convert this to .net. But i think it will make the job easier to strip out the MFC stuff and replace it with ANSI C++. I want to get it all working in a console app, so the MFC stuff is causing all the problems!
Well i think?
In the code i have.....
CTime time;
CTime datavalue;
CTime is a MFC datatype, this i believe is different from the ctime method in the time.h.
Is there a ANSI C++ class that will replace this?
I thought about this a wrote a class like this....
class Ctime
{
public:
time_t GetUTCTime(void);
};
time_t Ctime::GetUTCTime()
{
time_t UTCTime;
UTCTime = time(NULL);
return UTCTime;
}
its missing a pointer, because i've spent so long in the .net world i've forget how to write C. I'm not sure if this will work anyway but at least i'll have the basic class replacement.
thanks..

You confused me if you're going.NET or not.
If you do, you have all the time functions you'll need in .NET won't you ?
|
|
|
|
|
eh,
you have int,double and string as well but you still need to make the existing code work, compile and build before you can convert to .Net
just because .net as these function, isn't an answer you've missed the point!
The existing code creates an instance of Ctime which is a MFC function, if i dont use this or an equivalent method, how can leverage .net time functions in C++

1. OK.

What would be the use of having a transparent window on top of notepad. Why do you want to do this. Do you intend to capture the user entered text and display it in your window instead of notepad?
Somethings seem HARD to do, until we know how to do them.

1.CreateWindow()-can create window ,but i don't know how to implement the transparent effect.
2.i have implemented the transparent window,but the Grab software can't grab my transparent window.And,i don't want to use the API 'SetLayeredWindowAttributes' to implement the transparent effect.because the func is used for win2k and winxp.
3.i want to let the transparent window become watermark

i did the following code for showing progress and status bar and while running the code the progress bar alone gets displayed first with the status pane empty,and the status bar gets displayed after that finally,i need the statusbar to display "scanning",along with progressbar,what should be done????
m_bar.Create(this);
m_bar.SetIndicators(indicators,2);
CRect rect;
GetClientRect(&rect);
m_bar.SetPaneInfo(0,progressbarn, SBPS_NORMAL,rect.Width()-100);
m_bar.SetPaneInfo(1,progressbarm,SBPS_STRETCH ,0);
RepositionBars(AFX_IDW_CONTROLBAR_FIRST,AFX_IDW_CONTROLBAR_LAST,
progressbarn);
CString s;
s="scanning";
m_bar.SetPaneText(0,s);
pPrgCtrl->Create(WS_CHILD | WS_VISIBLE, CRect(10, 10, 288, 35), this,0x16);
pPrgCtrl->SetParent(&m_bar);
CRect crPaneRect;
m_bar.GetStatusBarCtrl().GetRect( 1, &crPaneRect );
crPaneRect.DeflateRect( 0, 2, 2, 2 );
pPrgCtrl->MoveWindow( crPaneRect );
while(condition==success)
{
while(pPrgCtrl->GetPos()<100)
{
pPrgCtrl->StepIt();
}
break;
}

Hi...
I am trying to create a log file which should contain..
///////////////////////////////////////
TSE0001
TSW0001
TSI0001
/////////////////////////////////////////
Then i will find the particular string "TSW".
It should increment as
TSW0002
but i am getting as TSW0004..plz help me...
my code is..
/////////////////////////////
switch(cType)
{
case 'W':
{
int iTSWCount = 0;
while(!inFile.eof())
{
inFile.getline(aLine,1000);
int iWPos = strLine.Find("TSW",0);
if(iWPos!= 0)
{
iTSWCount++;
}
}
iCount = iTSWCount;
logfile<<"TSW000";
break;
}
case 'E':
{
int iTSECount = 0;
while(!inFile.eof())
{
inFile.getline(aLine,1000);
int iWPos = strLine.Find("TSE",0);
if(iWPos!= 0)
{
iTSECount++;
}
}
iCount = iTSECount;
logfile<<"TSE000";
break;
}
case 'I':
{
int iTSICount = 0;
while(!inFile.eof())
{
inFile.getline(aLine,1000);
int iWPos = strLine.Find("TSI",0);
if(iWPos!= 0)
{
iTSICount++;
}

What is cType? What is inFile? ...
1. You should provide the code, that is "relevant" to your problem. Nothing more, nothing less.
2. Please enclose your code within "code block". (Select your all your code and then click on the code block option in the formatting pane). This will make your code more readable.
OK - Have you debugged to see why is your program not producing desired results?

BTW: your code need a bit refactoring.
BTW(2): your code actually counts occurrences of the string, if you really need to increment the number represented by the string the you should first convert the string into a number and then increment it.

So your compiler is like this:
try
{
....its urgent
}
catch(...)
{
MessageBox(_T(its not a standard question!));
}
finaly
{
MsgBox(I ignore messages that have "urgent" keyword in them. )
}
