Completely new to C++ and have been given a task that includes creating an application that uses CString data from a completely separate .h file.
The CStrings consist of info that I need to be able to copy to the clipboard, then be able to paste that text into word etc. I have set up a button in the application so when that button is pressed it executes what I want it to do (read the CString data and copy it to the clipboard).
For a person of my skill level this is difficult and my colleagues do not have the time to support me on this learning project so I thought I could get some advice and pointers here. Any help would be greatly appreciated. I am an apprentice working in software for 2 months.
Hello guys. I am trying to make a simple TSP using Julmar TSP SDK. I am able to make a skeleton TSP which gets detected by Windows and its added line can be seen from Phone.exe.
I want to add a thread in this TSP, which generates fake call to Phone.exe
How do I take it further? Should I add a main()and instantiating all the classes in it, in my .tsp project? Or will I be doing something in TSPUI project (so that I setup few things during manual installation of TSP)? Thanks for giving any pointer.

. But It's wall clock, I'm not sure that I can estimate performance by this way, besides, I need approach which will allow to measure time of each function which I choose. I've heard that there is approach to use CPU-time.
For high accuray difference time measurements with Linux use clock_gettime[^] with timer ID CLOCK_MONOTONIC or CLOCK_PROCESS_CPUTIME_ID. This requires including time.h and linking with the real time library librt (link option -lrt).
Yeah. There is such approach like, count the number of ticks to estimate performance. I do not think that it's panacea.
Richard MacCutchan and Jochen Arndt also correct.
But I guess that you mean universal and independent implementation version. Look here.
I am an innocent bystander of a discussion about how #include directive is handled in IDE.
The IDE in question uses proprietary file "main" name extension (still a text file) and processes #include <header.h> and #include "local_header.h" in that file just fine.
However, when the local_header.h file has <b>another #include <header_1.h></b> in it the compiler "does not see that". That is basically what people who "knows / developed" the IDE are saying.
Including another local file in first local file such as #include "local_header_1.h" is "seen / processed " by IDE.
I was under the impression that #include <file.h > tells the OS to find the file "anywhere" and #include "file.h" tells the OS to search only current / parent directory.
This variant is used for system header files. It searches for a file named file in a standard list of system directories.
This variant is used for header files of your own program. It searches for a file named file first in the directory containing the current file, then in the quote directories and then the same directories used for <file>.
A compiler is not an IDE. An IDE is a front-end to a compiler and it should follow the same rules as the compiler (and pre-processor in this case). If the IDE does not, then it is broken and must be fixed.
Obviously I got the compiler mixed up , so here is the way I view the whole mess.
To get from idea to running code I see these basic blocks
Operating system - with environment configuration
Development application (IDE )
Main file .*ino
"System " includes - example <stdio.h>
IDE "libraries" - example <LiquidCrystal.h>
Local includes - example "MyClass.h"
Compiler / linker (preprocessor)
I think I need to take a look how the compiler handles / finds the path to each include.
I can see if local includes are in SAME directory as the x.ino file it works fine.
But the "system" or "library" includes path are different and that why if fails.
But I want to write code and not troubleshoot the IDE.
Maybe I should use a different IDE.

There is nothing to troubleshoot. Whether you use the IDE or not, the issues are the same. The compiler needs to know the paths of any directories which contain header files that you wish to include in your compilations. The linker needs to know the paths of any directories which contain libraries that are referenced by your project. When you install Visual Studio it sets a default set of both, which gives the paths to all the default library components. If you create a project that uses other headers and libraries then you need to add those paths, and the library names, using the Project Properties link in Solution Explorer. If you want to do it without using the IDE then it is much more hard work and you would probably need to set up some complex batch files, or learn how to use Make: something that is not for the fainthearted.
I'll take wild guess what you are going to say...on better not...Anything after ONE file is a challenge.
Negative. I was just trying to narrow down the problem a bit. The Arduino IDE uses the avr-gcc compiler. That compiler's preprocessor, like others, has a list of directories it will search to resolve #include directives. This is usually the -I command-line switch.

Hi i am developing an application CListCtrl based, which can open more files listed inside, to do this i did thread for every file will be clicked, the problem is when i close a file i'd like to do some check operations on file, but using WaitForMultipleObjects it wait first i close all files and then perform the operations, with WaitForSingleObjects it wait only for first file and ignore the others.
I'd like so:
1) i open the file1.pdf - the program wait.
2) i open the file2.pdf - the program wait.
3) i close the file "file1.pdf" - the program perform operations on file1 (the file2.pdf is waiting)
Please i hope somebody can help me
