Hi!

I think that the plugins featrue is gonna be GREAT. Thank you Jon. That's why I started to download somt C++ tuts in order to learn it. I would like to code my simpel OCR program in C++ cause I think that would be much faster, woudn't it?

If it could be faster, I have just 2 short questions:

1. How do I initialize a two-dim array?

2. How can I get the color of a pixel anywhere on the screen?

Thank you in advance, peethebee

This probably should have been in the Support forum, but anyway.

1)

Dim $a2dim[2][3] = [ [ 3, 1, 4 ] ,  [ "Testing", 3.1415925, exp(1) ] ]

2) Look at the help for the PixelGetColor function.

I thought he was asking how to do those things in C++. Hence the post in the Development forum, the mentioning that he was coding the OCR program in C++, and the asking of two questions that would have obvious help-file answers if they related to AutoIt. That was just my impression, though.

Yes, he is asking for the C++ code.

Getting pixels is VERY slow. I don't know the C++ code for it... but my C# program (I assume you still have) has a FastBitmap class that is 30x faster, or so. I suggest writing this in C# using the code I already have.

Hi!

I would take you solution, Insolence, but I would like the program to be a plugin so that you could use it easily in your program...

Perhaps you can call not only C and C++ but C+ programs too, if they are exporting a DLL... (we could make a UDF which calls it via DLLCall)

Yes, you can make DLL's with C# that will work with AutoIT, I assume.

And this will require 24 mb .NET framework, right? :whistle:

Yep :dance:

Not that good if it requires .net, although most Windows PCs have it installed already I think because of other programs requiring it.

Hi!

This thread is quite intersting about performance of plugins:

Ok, time for the C/C++ answers. :">

1)

int a2dim[3][2] = { { 3, 1, 4}, {1, 5, 9} };

Now where do you think I got the syntax for array initialization in AutoIt? :whistle:

2) No clue. Sorry. Check the help file of your C++ compiler to see what API functions can give you that information.

There have been several requests that should have been in the support forum that were posted in developers instead. I thought this might be another one of those. That is why I answered it that way. I did like the praise for plug-in, though.

C# is slower then C++. If you rewrite it in c++ it will be even faster.

<{POST_SNAPBACK}>

How much slower? Would you like to rewrite my program in C++?

Let's all go to Microsoft to demand the discontinuation of the .NET Framework!  ;)

It will eventually go the way of VB... Nothing beats a quality C/C++ coder.

What about an army of ill-educated C#'ers? ;)
