C++ :: Base Project - Restrict Header File Inclusion
Aug 21, 2014
I have one requirement. I have a project lets Say baseProject.vcxproj. It has some header files. Another project lets say dependentProject.vcxproj loads baseProjects's dll and uses some of its header files.
When some other project lets say unrelatedProejct includes the header file from e dependentproject which includes baseproject's header file. It makes to change the include driectory setting of unrelatedproject. How to avoid this.?
So I wrote a program to turn a binary file's data into an unsigned character array for inclusion in an executable. It works just super.
I'm wondering how I can write a program that will perform this operation on every file in a directory and all it's sub-directories so that I can I can include everything I need all at ounce.
I'm a beginner with C and wonder how to include single header files (*.h) in to my project. I mean header files which are not included to the standard installation package.
I thought it would work if I just copy the newheader.h file in to library folder c:MinGWinclude, but it didn't work. Is there some kinf of GCC -command or procedure to add these single header files or how it should work?
All of those standard header files are working well and I don't have any problems with them.
if I include iostream twice in my project why is that valid? Wouldn't the linker see that there are two definitions of it and report a error, but it works?
I just wanted to add strings in any base form (example 1101+100 = 10001 in base-2 but it could be added using any base-form like in base-3 to base-36) and I'm having a big trouble with my code because it gave me incorrect results.
addition(char st[], char st2[], int base){ int i, j, carry = 0, ans, len, o=0, z=1, l=0; char final[50]; if(strlen(st)>=strlen(st2)) len = strlen(st); else len = strlen(st2);
I'm very new to MFC & VisualC++. I'm using MSVS2010 Pro. I am trying to write/debug a simple form that saves and restores the content of some edit controls. It seems to work as expected, except the file saves only to the Project Folder, regardless of where I browse and select to save the file.
Code: void CMFC_FileDialogDlg::OnBnClickedbtnsave() { this->UpdateData(); CFile f; //Kinda Correct, Works but still saves in Project Folder BOOL b_OpenFileDialog = FALSE;//this doesn't act as bool in CFileDialog?

My only experience is a little simple VB programming in Excel, so any specific examples??? Also, rules seem to change from version to version? I have to "update" a number of undocumented programs.
I'm doing error checks in C and I'd like to know how to restrict the input of a string to 2 letters and if it is exceeded, i'd like to loop and ask for the code to be re-entered.
Code:
for (i = 0; i < code7; i++) { printf("Enter number of items: "); scanf("%d", &item_qty[i]);
I am trying to write up something to have a user to enter a four digit number. Only four digits, Ex: 0001, 0116, or 9999. There is no getting around the selection 0001 or 0002. I understand if not done correctly, the first three 0's will be ignored.
I've been just playing around with what I have below but I just don't remember how to do it nor can I find a good example online to figure it out. I know it is not correct just typing to try to remember. I am aware that it is gibberish right now, this is just me brainstorming.
int number; cout<<("Please enter the four digit number(Ex: 0001): "); cin>> setw(2) >> number; cout<<)"Please enter four digit date. Two digits for month and two digits for year: "); cin>> date; if (number< || number > 30) cout << "Invalid choice. Try again." << endl; cin.clear();
I was creating a template and I realized that certain data-types/structs/classes would not be applicable to my template.This would cause bugs and errors if used incorrectly. Is there a way to restrict a template-capture to certain types/classes?
I got this algorithm of conversion and now I'm stuck at how to code it.
"Algorithm to Convert From any Base to Base 10 Decimal."
Let 'n' be the number of digits in the number. For example, 104 has 3 digits, so 'n'=3. Let 'b' be the base of the number. For example, 104 is decimal so 'b' = 10. Let 's' be a running total, initially 0.
For each digit in the number, working left to right do:
Subtract 1 from 'n'. Multiply the digit times b^n and add it to 's'.
When done with all the digits in the number, the decimal value should be 's' .
I have a project which does a specific thing, like an open file dialog.
I would like to open it in a different project on a click of a button.
Also, It has a different namespace.
I'm guessing that it would involve a "using" statement to add the namespace And I will have to add reference to an *.exe or *.dll -> I'll have to look up how to make a *.dll, I know where the *.exe file is.
I have searched for a different things on Google, but I don't think that I am looking for the correct phrase (which is always frustrating...)
How to rename a textfile in a Visual C++ CLI GUI project. I've tried using the 'rename()' function but that isn't working for me (probably because of the type of project).
this last few days I've been coding this one particular file
Hero.cpp
namespace Hero { namespace { // all data here } }
then the code grew a bit to about 700 line
Then now I want to implement hero skill system It needs the access to data inside the unnamed namespace where I put just about everything.. but it's unnamed namespace, it's only valid within one file and I should hide all that data from Hero interface in Hero.h How should I do this ?
I have a dll file and i want to add this dll file in my c#.net project reference through a program. I know I can add it by clicking copying and paste ,but i want to add reference programmatically.
I'll just tell you in short how my Problem looks like: I should implement a New Class in a SourceCode i didnt write myself. The source code is extremely sized (i think approx >100.000 Lines of Code), so i dont want to change too much in it in order to get my Implementation done.
MY problem looks simplicified like that: Starting from 3 classes and my new class the pseudo-code looks like that:
So, i need Parameters from 3 different classes to insert in my NewClass. The 3 Classes dont know anyting about each other. So, i need to implement a Class-Instance from Type NewClass which is known by the other 3 Classes. I did solve it in this way:
I just wrote a headerfile with a class-instance which is getting included by the other 3 Classes. So they all know the same Instance and writing their Parameters into it. Is this a decent solution or could it happen to get bugs/ logical mistakes with it?
I have written my program and it works when I keep everything in the header files, and then have my main. I am now splitting them up into implementation files, but Eclipse keeps giving me errors. It gives me error at every opening brace of the constructor and functions. It says on all of them "Redefinition of (name of constructor or method), Previously declared here." What am I doing wrong, because it works in the header file?
I need to convert an integer, for example 10, to its base 16 equivalent, 16. I found this code that converts a base 16 number to base 10, but I need the opposite. Plus, this code doesn't seem to work properly with input values under 32.
I'm working on a cross-platform threading project, the aim is to start 1 worker-thread that has a queue of worker-items which are serviced by the thread.
The threading framework works fine, both under Windows and LINUX, albeit as designed under Windows, and in a modified form under LINUX.
I have this CSnmpTrapd class which is designed as a worker-item for the worker-thread, it listens for incoming SNMP traps and decodes the packets, this is implemented in csnmptrapd.cpp and csnmptrapd.hpp.
1) When I add this piece of code to my makefile and re-compile the app successful... the app will start (or not?) but generates no console or file logging as is expected, it will not even show printf() output which was added as first statement in main(). My app handles CTRL-C to terminate and this works !?!? But I'm actually not sure my app works at that point.
2) When I compile the app without csnmptrapd.cpp and start it, it will generate console and logging output and behave as expected.
3) When I add the CSnmpTrapd class implementation to an existing cpp file in the project, it will compile and run as expected... the worker-thread handles the CSnmpTrapd worker-item as it should, incoming SNMP traps are captured and decoded, logging generated
I have this image/video compression project that is to be done in C. I've been given this source code by my supervisor which is supposed to be a working one.
Assuming I have a sequence of 5 images in .pgm format (image41.pgm, image42.pgm .... image45.pgm). Some of the code involved is
When I tried to compile the code using make file (shell script), I got this error message "In function 'readPgm' format '%d' expects argument of type 'int *', but argument 3 has type 'unsigned char *' "
Can identify what the problem is and how to rectify it?
