For each project in a VS solution it's possible to stipulate per-project folders that get searched in addition to the folders that you've set globally for Visual Studio.
Which folders take priority? Do the project's folders get searched first? Or do the global folder get searched first? Or is it possible to select one set as having priority over the other?
(this is VS 2005 BTW)
I want to include boost directory. What must be in the Additional Include Directories input?
I tried
C:C++boost_1_55_0libsaccumulatorsexample;$(BOOST_ROOT);%(AdditionalIncludeDirectories)
But I am still getting error "Cannot open include file: 'boost/libs/accumulators/lambda/lambda.hpp': No such file or directory" when I include
Code:
#include <boost/libs/accumulators/lambda/lambda.hpp>
The file is placed out side of boost directory of sure.
I am trying to include library paths in VS 2012 through the new property pages.I downloaded and installed mpich2-64 bit libraries under "C:Program FilesMPICH2include" and set the include path in Microsoft.cpp.x64.user property file so the path now looks like
Code:
"$(VCInstallDir)include;$(VCInstallDir)atlmfcinclude;$(WindowsSDK_IncludePath);C:Program FilesMPICH2include;"
But somehow it fails to find the files.
Code:
fatal error C1083: Cannot open include file: 'mpi.h': No such file or directory
The file is definitely there, so what could be the problem ?
I have been reading up, and it seems that all I need to do to finish up the installation of a library is to add in the search path for the library upon compile time.
Of course, I also read that directly copying the lib files can work too, but that may result in the over-writing of necessary files...
I read a more thorough document on mingw's linking processes and discovered that I could create a folder, install the library in that folder, and add the folder as a search path for mingw (so, basically, all i have to do is install all my libraries under that folder).
Using CodeBlocks. I've added the path to the library files in 'search directories' in 'linker' tab.
E:DataCompLibrarySDL2-2.0.3libx86
I also added the include files location in 'search directories' and that works fine.
But still when I add 'SDL2.lib' in linker settings and try to compile I get: cannot find -lSDL2.lib

This refers to an ATL COM DLL project. I can successfully create a class hierarchy of objects, ie. say, one class is the TEAM, which then holds other objects, say, a leader and a secretary, both of which are Employee Classes . Here goes my question:
a) In the Team.h header file I declare m_pLeader as a CComPtr<IEmployee>
Code:
classATL_NO_VTABLE CTeam :
public CComObjectRootEx<CComSingleThreadModel>,
public CComCoClass<CTeam, &CLSID_Team>,
public IDispatchImpl<ITeam, &IID_ITeam, &LIBID_BUOBJ05Lib, /*wMajor =*/ 1, /*wMinor =*/ 0>
{
private:
CComPtr<IEmployee> m_pLeader;
CComPtr<IEmployee> m_pSecretary;
b) The Employee Class is defined within this ATL COM project.
c) In the Team.cpp file, I create an instance in the FinalConstruct code, the focus is on the CEmployee
Code:
HRESULT CTeam::FinalConstruct(){
CComObject<CEmployee>* pLeader;
HRESULT hr=CComObject<CEmployee>::CreateInstance(&pLeader);
if (FAILED(hr))
return hr;
m_pLeader=pLeader;
// ..same for secretary...
return S_OK
}
d) Here comes my QUESTION: How must I proceed if the Employee object was part of another ATL COM DLL, that is it would be described in another DLL that I would now like to reuse? I guess I need to
1. Have the other DLL's idl-, tlb, and h file in my project folder. Let me name it "other.h, other.idl, other.tlb"
2. Both h- and cpp-file must have an #include "other.h" statement -- please correct if I am wrong..
3. ...but how must in the Team's h- and cpp-files the statements be (assuming the class in the "other" Dll is Member (instead of Employee? I know the following code will NOT work, so I am asking how it should be correctly?
Code:
private:
CComPtr<IMember> m_pLeader;
4. and in cpp file for:
Code:
CComObject<CMember>* pLeader;
HRESULT hr=CComObject<CMember>::CreateInstance(&pLeader);
[/code]
I m working calculating stuff in files, input and output data, etc..., the question is the following: I output double numbers with:
myFIle << fixed << setprecision(10) << double;
The problem i got is that when a numer is like 193123.2 it prints like 193123.200000..., so finally, ¿how can i print it with any additional 0 that i need?.
How would I add my own function to the vector class?
View 3 Replies View RelatedThe problem is that my DataSelector form, which is instigated from the PropertyGrid (by creating a UITypeEditor) has access to the property LinkedDataItem. However I want the DataSelector form, which currently lists all the DataItems in the DataManager, to only list DataItems which are supported by the CustomControl, therefore my DataSelector class also need the "SupportedTypes" property from the Custom Control. How can I do this?
I thought maybe I can use a type converter to reference the custom control itself, instead of just the LinkedDataItem, and just show it as the Linked DataItem, but I am unsure if this is the correct use or how to do this.
Remove the break statements from each of the cases. What is the effect on the execution of the program?
Add an additional switch statement that allows for a Passing option for a grade of D or better. Use the sample run given below to model your output.
Sample Run: What grade did you earn in Programming I ? A YOU PASSED! an A - excellent work!
Rewrite the program LastFirst_lab44.cpp using if and else if statements rather than a switch statement. Did you use a trailing else in your new version? If so, what did it correspond to in the original program with the switch statement?
// This program illustrates the use of the Switch statement.
// The break statement causes all subsequent expressions to be executed as well, also known as "falling through".
// The trailing else statement acts just like the default section if none of the options from before work it gets "defaulted" to it.
#include <iostream>
using namespace std;
int main() {
char grade;
cout << "What grade did you earn in Programming I ?" << endl;
[code]....
how do you add an additional switch statement? i tried multiple times and i'm not sure if i don't understand braces enough but it didnt seem doable. also, I'm not sure what the teacher wants me to submit.

I have a non-MFC static library which I share between a number of different projects, some non-MFC and some MFC. Currently the static library uses a typedef of std::wstring and std::string for UNICODE and non-UNICODE builds.
After discovering it's possible to use CString in non-MFC applications, by including atlstr.h header, I decided I'd rather that than using stl strings and having to keep converting between the different types. However, I seem to be struggling with linker errors when linking the library with a MFC application.
Can I create a non-MFC static library using CString from atlstr.h and link it with a MFC application?

I'm stuck on unix system programming and am beginner about it. Assume that there is a directory which X. There are a file(text1.txt) and another directory which is Y in X. Last, there are two files(text2.noExtension) and text3.noExtension) and another directory which is Z in Y. My goal is that read files and enter directories until there is no directory. How to go on. Example:
Code:
#include <stdio.h>
#include <dirent.h>
int main (int c, char *v[]) {
struct dirent *pDirent;
DIR *pDir;
if (c < 2) {
printf ("Usage: testprog <dirname>");
return 1;
[Code]...
So first, I'm sending files from a server to a client. Basically, the server says "Incoming file" and tells the client "The name of the file is: ". So taking the name, I need to create folders, if they don't exist, for the received file to be placed in (since std::ofstream doesn't allow creating directories).
My current code below is working. My trouble is listed below the code.
std::stringstream ss (name);
//name is the recv'd name
std::string token;

I replaced the myfile.txt with the directory of the file I want deleted.

I am debugging a library. I can step into the code however the watch window doesn't show the values of any variables. It will display a message in the value field:
Code:

Interestingly it does show values for local variables in that function but not member functions. Most of my data members are member function though that I want to debug. I am using VS2010.
I have these two files:

I have two report.h files located in two different directories. However the contents of them are different. How can I include the report.h file located in guarddog into the report.h file located in sky?
I assume just doing this would be ambiguous:
#include "report.h"
I am currently working on a program that will take an image and compare it with all other images in the current directory and sub-directories. I decided to use Qt for this as Qt has a QImage class with an overloaded == operator. This seems to work well if there are duplicates of the same size.
However, my goal is to not only find duplicate images of the same size, but the same image which may be a different size. To do this, I shrink the larger image to the size of the smaller image using the QImage scaled function.
The concern I have with this is that the scaling isn't done the same way the smaller image may have been scaled. I tested this by shrinking a copy of a picture in Paint, that image does not get deleted. I believe that == is looking for an identical image, so when I do the shrinking (via that scaled function), even if it is of the same picture I shrunk in Paint, the two methods of shrinking are not identical, and so the images appear different.
Any better method I can try? Something that can allow for slight deviations, such as an image being 99% "the same" as another. (I admit here that I will need to define some metric for what "the same" means.) In this case, the method assumes they are "identical" and gets rid of one of them.
The main way I can think of doing this is to go through each image, one pixel at a time. If the two pixels from the different images at the same index are the same, then I can increment a same pixel counter. If this number is 99% (or some other threshold) of the total pixel count, I can make the assumption the images are the same.
