Excepted for the CreateDIBSection the method is almost what I thought: thanks!

I need to draw on the OnPaint event right?

I'm trying to figure out the easiest and best way to perform this task:

I have two PGM (portable gray map) images and i need to put one above the other in a MFC window. Then I need to link them...

Do you find that it may be useful sublassing the control?

What about solution number two?

How do I make "runtime deleting previous contents" ?

You don't want to set the entire background right?

Hi all, I'm using a edit box as an "append log" for my program.

I set it to "multiline" so I can write a new log every time. To write the log I append text using this code



CString strLine;...

Got it, but this time the application needs one task at time to be performed at full speed and cpu work

Anyway I suppose I'll use PostMessage and resource Ids.

By the way, if I can figure out...

Okay, I think the string resource ID is not a good solution (too messy), maybe I'll go for the SendMessage. It is synchronous isn't it?

Might be an idea... Can i pass an entire string with that right? Just a pointer..

Uhm I see, but AfxGetMainWnd() requires MFC involved. The application uses mfc, but these classes do not. Some of them are even plain C incorporated into a C++ application. Don't know how they would...

My application has...

Hundreds of thousands, I think you're right and a table is the only way to speed up the process

I'll try this as solution but the logarithm still takes part. Don't know whether I can get better response times

Yes release mode with optimization at "Favors fast code"

Just a little faster, but they are both slow :(

In my previous post I figured out (thanks to D_Drmmr) how to calculate arc cosine with real numbers (including numbers not in the range -1;1).



_acos =...

Thank you D_Drmrr, you solved my problem. I did not notice that, you was absolutely right :D

I am developing a project in plain C++ using VS2010, I need to calculate the arc cosine of a real value (can be out of -1;1 range, so need to deal with complex numbers) and compare it with a double...

You need to call the destructor of ActiveX controls before window's destructor

Thank you so much Lindley!

Problem solved with your help!!

Bump this topic: I need to solve this problem.


How can I multiply a matrix <double> single row with a complete matrix <double> to obtain an accessible vector of values with uBLAS?

I'll give it a try, thank you so much for helping me!
