From VC++'s online help, PBM_SETPOS treats wParam as the new position and ignores lParam (which should be zero).

Sir,
I am developing the code for rotation of the Rectangle and ellipse in my projects.I have seen hat SetWorldTransform() cannot function in 98.So I am searching for alernative method to rotate my rect.I should be able to save the rotated rect in my List containg the CRect objects.I would be thankful to you if I get The solution as soon as possible as it is to be embedded immediately
..............
I have rotated the rect by using XFORM structure and calculated the new values and have drawn the rotated rect using Polygon() function.But I am unable to modify my List rect object with these coordinates as that draws from the TOPLEFT to BOTTOMRIGHT
Sir u can provide any of the solution.
Waiting for ur reply

It sounds like you will simply need to create a new list and a new structure that can hold the four points that you need to store your rectagle. Or you could use your CRect class and the XFORM class, and you could generate the new rectangle on the fly with a conversion function that returns the translated points.
There is not a whole lot of native support for anything in windows that is not axis aligned.

Hi !
I'm looking for a custom control to provide a "variable watch" like control.
You can find such controls in every environments such as Visual C++ ...
It allows you to display the name and the value of variable selected by the user :
myVariable1 ....................... 0x12485
myVariable2 ....................... 48725
myVariable3 ....................... 1001100
myVariable4 ....................... 0x20 0x42
Does anyone knows where to fing such a control ???
Thanks,
Vince

THis sounds like the watch window (alt+3 in debug mode)

Sure !!!
What i'm looking for is not where to find the watch window of Vc++ !!!
I'm looking for a class witch wrap functions of a watch window in order to be integrated in my own application (something like a Cwnd derivated class...)

Is there any Date Time pickers that would allow you to modify both data and time within the same cell?

I have
p.CreateDispatch("DllwithForm.Class1");
p.CheckingPB(hPbWnd,0,100000);
where CheckingPB is triggering repeated messages to be sent to a control. If I uncomment the release dispatch , I am concerned that it will release the dispatch before all my messages have been sent and received. Is this a fact? Since the app isnt working anyways I cant check it out, but wondered if its disastrous if that line is commented out...
Thanks,

Help people, my head is spinning.....
I have an application that reads images back from a database into a directory. I need to 'touch' the file time stamp to match the database. The date field to retrieved as a COLEDATETIME and I need to convert this to a FILETIME in order to call the win32 SetFileTime() function.
Anyone any idea's how to perform this conversion (I'm sure is really obvious and the constructor for COLEDATATIME lets you do it the other way around!) --- Anyone any clues?

Use COleDateTime::GetAsSystemTime, then ::SystemTimeToFileTime.

hello,
Is it possible to have CreateDIBSection to allocate the bitmap in system memory rather than in video memory (without DDraw) ?
|
|
|
|
|
CreateDIBSection allocates bitmap data in 'system' memory, not in video memory.

The fourth parameter of CreateDIBSection (VOID **ppvBits) gives me values over 0x80000000, is it still system memory ?
|
|
|
|
|
|
It's just because I make memory access and they seem to be slow.
Never mind, I'll do more tests.
Thanks.

We delete an array of char this way:
delete[] str;<br />
str=NULL
But, if the string is created like str=_T("test"); or #define str _T("test"), trying to delete it results in an exception.
Now, my question is this: how can I figure out if the string is deletable or not? (must be a const prob)
I know I should strcpy those strings before use, but lazy me...

There's no portable way of determining if object is on the heap or not. Switch to std::string or CString and forget about it.

You can't.
Well, not without keeping some extra information anywhere.
Really this is a design problem, not an implementation problem - it's good practice to allocate and free memory at the same level of a program, so that level already knows how it allocated the memory.
For example
char* str = new char[100];
somefunction(str);
delete[] str;
char* str = "Hello world";
somefunction(str);
// No need to delete anything
The point is that "somefunction" didn't allocate the memory so it can't know how to free it and shouldn't try.
Basically whenever you allocate some memory you need to think about how it's going to be freed, and ensure that it's done at the same level as it was allocated, which is probably the only place that knows how to do it.
