Copy the bytes from the file, up to the byte in question, into a temporary file. Then copy the remainder of the file into the temporary file. Close both files. Delete the original file. Rename the temporary file. Make sense?

Yes, it's even safer than an 'in place' solution. Smile | :)

I don't know a direct way.

As workaround, you may enumerate windows and call GetWindowThreadProcessId in your callback.
hope that helps

Wrapper class to do minimize to tray and small minus minimize button

I don't think you understood me properly. A process ID represents a process. A process can have many windows, and generally does. Which of the process’s many windows are you after?

I'm looking for a wrapper class that can do minimize to tray and add the small minus minimize button on the top left corner of an application.

I’ve seen code for adding logic to minimize to tray, but I haven’t found any code that can add the small minimize button. For anyone familiar with Kazaa Lite, the minimize button I’m looking for is the one seen on the right upper corner of Kazaa Lite. I’ve seen it on a few other applications, but I don’t remember their names.

Does anyone have any good links for this?

I use a modified version of Adding Icons to the System Tray[^] for the tray functions.

Search Articles for "Title Bar" revieled a lot of articles, here is an example Animated System Tray Icon, TaskBar Icon, and TitleBar Icon [^]

Could some one give me idea how can i do that.

buffer[0]= 0xed
buffer[1]=0xb3

int16_t base= 12 bit(having value 3ed)+ lowest 4 bits are zero

Thanks-

Re: altering buffer value [modified]

base = ((0xb3 << 8) | 0xed) & 0x0fff;

thanks man it works Wink | ;)

could u plz tell me one more thing that if I have

(ABC... are bits)

uint8_t n8bit = ABCD EFGH

now I want to change this byte as like

// 0 zero

uint8_t n3bit= 0000 0FGH ???

thanks again..

Your question is a bit unclear (e.g., bits vs. bytes). I think what you want is:

n3bit = n8bit & 0x00000fff;

n3bit &= 0x07;

7 is the added value for the lowest 3 bits.
Here, Hex an Dec makes no difference, but I have given the hex value fore clarity.

Isn't

(0xb3 << 12) | (0xed << 4)

is it?

I'm not sure what you're asking, if anything, but that produces 0xb3ed0. If that's what the OP is after, great.

yes, but it gives 0x3ed0 when assigned to a 16 bit number. My doubt was about the lowest four bits, 'cause, IMHO 0x0FFF erases the highest ones. Anyway the guy was happy with your answer...

Which was confusing as I did not answer his question exactly, and why I entertained the notion that he was confusing bits and bytes.

CString::Remove is an option. But it will remove all occurances of that character from string.

You loop over the string and upon finding a space, you "eat up" all spaces following immediatly afterwards. When the next char is a non-space you continu normal operation.
