C / C++ / MFC

Hi Leon, This code is working fine for 2D points. Is there anyway to get the logic for 3D points? Thanks in advance. Regards, Gopinath.

that's what I am doing; just annoying to have to create images for many combinations. Thanks. I'd rather be phishing!

I hadn't seen that particular post, but I've seen most of the links listed there. I did try adding ftps:// to the server name, as suggested in that link, but that returns and invalid url error. I was hoping for a simple solution but it looks to be more complicated than I hoped. Thanks for the help!

Thought he wanted to draw in the frame which is non client .. that belongs to windows (the O/S) not the app (the client). It's so easy to draw in the normal client screen area with MFC didn't think you could mess that up ... Anyhow he worked it out. Moral never over-estimate the question being asked :-) In vino veritas

Very good idea. I think I would try this solution too, however, the location from HARDWARE\... seem to show what I need it.

Set the compiler flags -std=c11 or -std=c99 either standard will accept the code The portable case has to work or you are on an old C89 compiler which I find odd given it accepts the shortcut syntax in 1 The only other choice is you are on something like a PIC where you have to use builtins to get function addresses because of the crazy 32K block arrangements on memory In vino veritas

What about The Documentation? Enumeration declaration - cppreference.com[^] And other resources? https://medium.com/@nonuruzun/overloading-input-output-operators-in-c-a2a74c5dda8a[^] .

test_and_clear is a macro you can't use it as a function, macros don't return things without hijinx :-) GCC has a thing called a statement expression Using the GNU Compiler Collection (GCC): Statement Exprs[^] However I strong suggestly you don't do it just create a proper function (that is after all what you are trying to write) and inline it if speed is an issue. In vino veritas

Very probably there is, but, unfortunately, I am not aware of. I do use a little Lua script for the purpose. Lua features powerful string manipulation functions and it is a very enjoyable scripting language. You might also use a more popular scripting language, like, for instance, Python (another option is, if you like it, using the C++ 11 regex classes).

Bonjour, //hi essayez avec : //try with arg=v*pi*i/n; k++); //two time i++);

My product is quite low-level, i.e. I'm setting up impedances, gains, current limiters, bias voltages, differential signal on/off, generating PWM signals, etc. Also, communication protocols are cascaded, for example a PC is transmitting a USB-packet to a microcontroller, who in turn forwards this over an SPI-bus to another microcontroller, who in turn forwards this over a CAN-bus, etc and then an ACK/NACK-packet has to travel the opposite direction. So, to have "local" interfaces between different microcontrollers would make this packet forwarding extremely confusing. Especially the CAN-bus is a bit troublesome because of the limited payload size (8 bytes/packet and no, we can't use the improved version that clocks the data faster) and sometimes I need to send several kBytes of data.

I gave the value which is already there.. I gave a different number which is not already used and that solve my problem.

Sorry I misread the question. I have tried a number of variants but cannot get it to work. it would appear that #define statements are not accepted inside a macro definition.

Sorry, I cannot see anything obvious. Also, I am afraid I don't use MFC, so cannot try a similar test.

That was the problem, on #define: I assigned with '='. My bad !

Now that I have understood everything and got the right result, I read my question with a smile. Thank you very much to everyone who sent me in the right direction.

OT means "Off topic". I am replying to a message but discussing a different subject.
