Hi all,
I am trying to set some Background colors to CpropertSheet Tab controls.
I have tried Handling
OnPaint
OnCtlColor
OnEraseackground to acheive it.But none is helping
This is a Samble code which i used in EraseBackground handler
CPropertyPage::OnEraseBkgnd(pDC);
CRect rect;
CTabCtrl *tab = internal_sheet.GetTabControl();
tab->GetItemRect(0,&rect);
pDC->FillSolidRect(&rect, RGB(255, 0, 0));
return true;
This also not working
I am also trying to set the Tap position from the default left side to Right
This ModifyStlye(0,TCS_RIGHT); Positioning the tab in the bottom side.
ans the "TCS_VERTICAL" is not showing other tabs.
Please throw some ideas to acheive this.

Does this work?
BOOL CMyPropertyPage::OnEraseBkgnd(CDC* pDC)
{
CRect rect;
GetClientRect(&rect);
pDC->FillSolidRect(&rect, RGB(255, 0, 0));
return TRUE;
}

Hey,,,
I have a fer function that wait for input for a while...
at the moment... I code it simple like this...
for(i=0; i<50000000; i++){
//waiting for input
}
As Processes inside the loop are changing, the loop takes longer and shorter amounts of time to complete.. 3sec to 50sec.
what the easiest way to set up a timed loop that loops the same amount of time every time?
Example:
While ( time < 10Seconds ){
//wait for input
}

Hi!!,
u can put a counter inside the loop that increments to a particular no every time
e.g.
int count=0
for(i=1;i<=50000000;i++)
count = count+i
|
|
|
|
|
Later I'll be adding a "wait time option" so I gotta go by time... Just looking for the easiest way to code in a timer into a loop.
|
|
|
|
|
Ok.. I think I figured out the easiest way 
DWORD dwStart = GetTickCount();
while( GetTickCount() - dwStart < WAITTIME ){
//loop for WAITTIME milliseconds
}
|
|
|
|
|
What about WM_TIMER ?

I am confused that why we have to pass a reference of same class type into a copy constructor? I searched a lot but i am not able to find out the exact answer.So,plz if anybody can forward me the relevant answer of this question then plz forward it as soon as possible.Please specify the reason.
thanks..

For that you need to know, in which cases copy contructor constructor get called.
One of the place where it is called is when we pass parameter by value.
Thats why, to avoid recursive call, prameter to copy constructor is passed by reference.

Obviously you'd.
Read it here[^]. I suggest you to read a good book on c++ or rather on the object oriented paradigm.

Which part are you confused about: the reference has to be the same class or that you have to
pass a reference?
The reference has to be the same class because it is a copy constructor - used to construct a copy
of an object of the class, as it's name implies.
The reference has to be there because it's the only way to access the object which needs to be
copied.

Hello everyone,
I am creating an array of structure as
struct Table
{
RFC_CHAR fieldname[35],
fieldvalue[255];
};
Table t2[2];
Now i m initialising this array in a funtion and i want the funtion to return this structure
as well as in another function i want to recieve this array and finally i want a pointer to point to this function
please tell me how can i do this
|
|
|
|
|
And what is the question?
Maybe you don't know how to pass the array?
Then have a look at the following code snippet:
<br />
void testStruct(Table *tp)<br />
{<br />
tp[0].fieldname = ...<br />
<br />
}<br />
hope that helps...

no i dont want to pass the array to a function
i have created array of a structure and initialised it in function A and A returns this array
the struct is declared global
now in function B i want to call funtion A and take its return value which would be the array in an array variable 
|

Sorry, I can't figure what do you want to do...
Can you please post the code snipped that is giving you troubles?

Table *SomeFuncThatReturnsIt( void )
{
Table *pTbl = new Table[ 2 ];
if( pTbl )
{
}
return( pTbl );
}
Something like that will allocate the array of structures, initialize them as required, and then return a pointer to the array, or return NULL if allocation fails (if your new works that way). The caller is now responsible for deallocating the memory referenced by the pointer, of course.
This is not generally how I like to do things, because I avoid hand-off memory whenever possible, but I believe it will get you in a direction of what you want to do.
Peace!

I'm developing a set of classes to read the infamous 'index.dat' files. There is very little information about the format of these files available, so far most of my searches have turned up viewer utilities and info on how to delete them, but nothing much on the actual format.
Looking through a hex dump I have managed to identify maybe 30% of the items. If you know or have come across any details about these files, I would really appreciate your help.
