The code is like this:
{
CBitmap tempBitmap;
...
HBITMAP hBitmap = HBITMAP(tempBitmap);
m_picHolder.SetBitmap(hBitmap);
...
}
When call SetBitmap again, the bitmap can be shown out. But it will disappear after minimize and maximize the dialog.
Thanks,
Eric

You need to create on heap , using new.
Or , make CBitmap object, as member variable along with m_picHolder.

I think tempBitmap is deleted when it goes out of scope, which also deletes the gdi resource it's wrapping.
Try adding a CBitmap member variable to your class like:
CBitmap m_bitmap;
then in your function:
{
m_bitmap.LoadBitmap(); // or however you're getting it
m_picHolder.SetBitmap(m_bitmap);
}

Now, I am want to use bitwise operation, ex: add 1 or 0 to position in 8_bit. But I don't know about this.
Can you help me?
Thank's lot.
Best regard!

I need a program that operate with bit.
Example:
unsigned long x;
I want to put 1 or 0 to the 6th bit in x.
Can you help me?

Well, the numbers you want for each bit are:
1
2
4
8
16
32
64
128
256
512
etc.
So, x |= 128 will set the 8th bit. x &= ~128 will strip that bit.

If you are saying the the eighth bit is the 27 bit you want to be set:
<br />
unsigned int v = 1;<br />
<br />
v |= 1 << 7;
<br />
v |= 1 << 6;
<br />
v ^= 1 << 6;
<br />
v ^= 1 << 0;
<br />
v ^= 1 << 0;

Set (1) high order bit of a byte:
unsigned char ByTe = 0;
byte |= 0x80;
Reset (0) high order bit of a byte:
unsigned char ByTe = 0x80;
byte &= ~0x80;

Do vectors or CObArrays (and other similar containers/classes) automatically free their memory when the object containing them is destroyed? In other words, I have a vector as a data member in my class. When my class is destroyed, does the vector free whatever memory it held, or do I have to explicitly do that in my classes destructor?
Thank you,
BP

I believe the containers allocate space for the collection of types and destroys the memory for all those types. However, if the types are objects that contain dynamically allocated memory, the objects are responsible for deallocating their memory. Also, if the types are pointers to dynamically allocated objects, then you are responsible to write code to deallocate the memory.

It depends. A vector will dispose of an object, but it will not call delete, if the object was a pointer. So, if the object is a class, and it has a destructor, it will be called. If it's a pointer, the memory will leak if you don't delete it.

Please help!

#include <string.h><br />

<br />
token = strtok( NULL, seps );<br />
}<br />
}<br />
that is straight from msdn it does what i need but
char string[] = "A string\tof ,,tokens\nand some more tokens";
i need that line to take the text from a edit box in the form of a CString and i dont know how to do it.

The EditBox has a GetWindowText method, which returns a CString. CString has a GetBuffer method that you can use to get a char *, which is the same as a char[].

error C2440: 'initializing' : cannot convert from 'char *' to 'char []
this is new to me.

I'd expect a cast to fix that.

you lost me there i can do simple things i dont even know what a cast is.
|
|
|
|
|
i think i got it
char *text = m_text.GetBuffer(m_len);
strcpy( text, m_text ); // directly access CString buffer
m_text.ReleaseBuffer( ); <--- added them 3 lines
//char string[] = text; <--- took that line out
|
|
|
|
|
Yes, this copies it across. A cast would be passing text like this:
(char[]) text
A cast changes the type of an object, assuming the cast is valid.

i need the conversion from binary to decimal and vice versa but in a very simple way without using libraries
