Re: CPropertySheet::OnCancel(): Any way to abort the cancellation?

[ Point distance from line? ] Xenos5-Apr-02 8:06 Xenos 5-Apr-02 8:06  Hello all, I am working on line tracker class that works for multiple lines like just as CMultiRectTracker works for rectangles. When I am finished I will release it for all to learn from, and it is working except for this. Anyway, my trig is rusty (very), and I need to know how I can determine if a point clicked is within x pixels of a give line. This is to select the line to work with. Given two line endpoints (P1x, P1y), (P2x, P2y), and mouse position (X, Y) how can I do this? Thanks a lot!

Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Is there a way to pass a "HANDLE" from a client's window to a dll in ATL? Bart-Man5-Apr-02 7:56 Bart-Man 5-Apr-02 7:56  Hello, I was wondering if there was a way to pass a "HANDLE" from a client's window to a dll in ATL? I have tried adding "HANDLE" as a parameter,but it didn't work. Is there a different way to approach this problem? Thanks in advance. Re: Is there a way to pass a "HANDLE" from a client's window to a dll in ATL? Chris Losinger5-Apr-02 8:04 Chris Losinger 5-Apr-02 8:04  you could try a Long, since in Win32 a HANDLE is a void*, and a void* is a pointer. and pointers are 32 bits long, just like a long. -c "Do you mind if I smoke?"

It worked! compare strings 5-Apr-02 7:25 5-Apr-02 7:25  Hello I want to create a function that compares two words (char*) and returns a percentile representing how much the two string are identical. I have some problems making the function perfect and I was wonderig if someone can tell me if there's an algorithm that do that or have some code already written. Thank you very much.

Is it as simple as how much of the strings (starting from the first char) are identical? If so, just loop from the beginning of each string until you find 2 chars that aren't the same. The progress divided by the length (of one of the strings) should give you your answer. /ravi "There is always one more bug..." http://www.ravib.com ravib@ravib.com Re: compare strings 5-Apr-02 8:01 5-Apr-02 8:01  Maybe i'm not perfectly clear. My function does exactly what you told me. I loop from the begining of each strings until I find 2 chars that aren't the same. But if I have the words "Hello" and "ello", I don't want to have a value of 0% since the two words are pretty identicals. Thanks for the answer. P.S.

This will return a match value of zero for these 2 very similar strings: "abcd" and "bcd". The algorithm should return the length of the longest same substring present on both strings. The "similarity" factor would be the length of the substring divided by the length of the longer string. /ravi "There is always one more bug..." http://www.ravib.com ravib@ravib.com Re: compare strings 5-Apr-02 9:48 5-Apr-02 9:48  Ravi Bhavnani wrote: The algorithm should return the length of the longest same substring present on both strings. The "similarity" factor would be the length of the substring divided by the length of the longer string. So "abcd" and "lbcd" would be more similar than "abcd" and "acbd"? That sounds wrong... (the first pair has a three character substring in common, but the second pair has only one character substrings in common. I personally would not consider the first pair to be three times as similar as the second pair.) Getting information about system performance ?
