Hi all,
I want to make a picture control in which i can display various types of images like bmp, png, ico and i want at runtime if i select a path than that images should display according to path.
But my problem is i don't want to use gdiplus lib in my code....
Can i do this work without using gdiplus if yes than how so
Thanks in advance

The CxImage[^] library would do the trick for you.

|
|
|
|
there are dozens of graphics libraries out there.

Why don't you like GDI+ (just curiosity)?

Why not ?
Is is an school assignment about image formats ? or do you really need to loose time and effort to re-invent the wheel on a paid salary ?
Watched code never compiles.

Hi Experts
I need at() feature in my STL List. can anyone help me out?

Maybe you should use a vector[^] which has at built in. Alternatively you could write your own using an iterator, but it's probably not worth the trouble.
It's time for a new signature.

|

If you need direct access to an element at a specific index in your list, why don't use a vector instead of a list ?
|
|
|
|
|
std::list is not a "random access" sequence (i.e. cannot use a random access iterator).
Watched code never compiles.

As Richard and the others have said, use vector if you can. If you really really really must have at-like functionality you can use std::advance to do it.

Thanks a lot....
It is working......

What about:
template <typename T> class mylist: public list<T>
{
public:
T & at(int n)
{
int i;
list::iterator it= this->begin();
i = 0;
while (it != this->end())
{
if ( i==n ) return *it;
i++; it++;
}
throw( out_of_range("out of mylist range"));
}
};

depending on how the at() is used you can shortcut operations by holding the current iterator around as long as add/delete/insert operations have not been done. Using the difference between last at() and current at() you can move up or down the list. It takes some work, but if you are doing big searches you wouldn't always want to start at the beginning unless the new at() command is closer to the start or the end. and if you do add/delete/insert, just invalidate the iterator, and start over as you have done.

naw... comes from using skiplists, which made me think that wouldn't be a bad method here if there aren't many add-deletes, skip-lists let you jump around lists rapidly.

If you use at() often you might consider something like a skip-list:

Skip lists would allow you to skip sequentially starting from the beginning on ever at() command.

Hi,
How to change selection color of CEdit control?
Can I put image on selection instead of color?
|
|
|
|
|
Hi,
If you handle the WM_CTLCOLOR message in your edit control you can change the characteristics of the display context used to draw the text, so you can change the colour of the text and, by extension, the inverse video colours used for selected text.
To the best of my knowledge if you want to overlay an image then you'd have to overide or replace the standard drawing code - which would be a lot harder.
Cheers,
Ash

Can you guide me with some sample code or link...
|
|
|
|
|
|
can we use class1 in class2 without include the class1.h file???
|
|
|
|
|
Yes, for example if class1 and class2 are both declared in the same file and class1 is declared before class2. Othwrwise, it depends on what you mean by "use". Next time try a bit more descriptive subject if you post a question, please, "hi" just won't do...

Hi back,
You can refer to a class that hasn't been defined (in simple terms not had it's .h included) but you can't do anything that requires the compiler to know the size or composition of the class. So, without the .h file you can...
- declare a reference to an object of the class
- declare a pointer to an object of the class
- assign pointer to objects of the class
You'd be pushed to say that this lot is "using" the class though. What you can't do...
- call member functions of the class
- do any sort of RTTI (run time type information)
- get the size of the class which in turn means you can't create objects of the class
Cheers,
Ash
