I created a new project in Qt Creator, the files included are the .Pro file, and the .Cpp file.
Qt does not recognize the headers I try to reference in the .Cpp file. I am pretty sure it's because of what I don't have in my .Pro file. What do I add to it?
.Cpp
Code:
#include <QApplication> ->No such File or Directory
#include <QPushButton> ->No such File or Directory
#include <QHBoxLayout> ->No such File or Directory
int main(int argc, char *argv[]) {
QApplication app(argc, argv);
QWidget *window = new QWidget;
I was created a dynamic library (Used win32 App) & compiled with no error.
Then i was created my main application (MFC) & paste the .h,.lib,.dll files from the source path(dll App Path) to destination path(Main App Path). If i used the below command in my app means the project working good.
Code: #include "Alg.h" #Progma Command(lib, "VTAlg.lib") & also paste the VTAlg.dll in my app path.
here Alg.h contains the some methods , In future i will edit the function like below for my client requirement but no function name & Arguments change. The changes made in inside function(Logically changed) only.
My client contains only .exe file + .dll file.
My requirement, So after change the method i will send only .dll file to my client
If i change my lib file name VTAlg2.lib instead of VTAlg1.lib (But Same Function name & Arg type)means how can i edit the code below
I have a project in VS2005 and I'm trying to add the two-finger panning gesture. Problem is, there doesn't seem to be a way to add this in Visual Studio 2005. None of the windows gesture code seems to be there. Is there a way to add this in VS2005, or can I only do this in VS2008 or later?
I'm doing a homework aasignment on templates, and i have to build a list. The problem starts when i am trying to add elements to the list. For instance if i chose to add 5 different elements (1,2,3,4,5) the output will be (5,5,5,5,5).
I have migrated my MFC application from Visual Studio 6 to VS2010. But the UI controls still looks the same as of old theme. How can i add the manifest file now to get the UI controls to be displayed as of the current OS theme. i.e. Win7 look if the application is run on windows 7.
Is it possible to add a MFCToolBar to the header of a MFCPropertySheet because every page which will be dynamically added during runtime will be using the same toolbar and if it IS possible I would much rather do it this way instead of putting the same toolbar on every page. I have enabled the header with height of 48 and have implemented the MFCToolBar code first in the constructor then in OnCreate. It does not generate any errors during compiling or at runtime however the toolbar does not show.
I'm having trouble finishing this program. What I'm trying to do is create a class for Rational numbers. Get input from user for denominator and numerator. Store the numbers without a sign, and for the sign store it separately in char. I'm not supposed to use accessor functions. The part that I can't seem to know how to do is use the info that was stored in the addUp function. This function need to add two rational numbers. i need to make this function general enough that it can handle two fractions, or a fraction and a whole number, or two whole numbers. What I already have here is readin function which reads in the numerator and denominator. setnumerator and setdenominator to assign positive values. setsign should get the sign of the fraction. Finally addUp should addUp which I explained before. I have some ideas about writing the tests, but can't seem to know how to implement it to the program. The main program is still empty but all I'm supposed to do there is call the class functions.
Code: #include <iostream> using namespace std; class Rational { private: int numerator, denominator; char sign;
I was trying to write a character controller but when I went to add my pointer to my character I get error
C2143: syntax error : missing ';' before '*'
I've looked at all my classes involved but I don't see any errors and Visual Studio doesn't report any other specific errors. Is there any way of finding the source of this type of error?
When I step into CMainFrame::OnAlohaHowAreYou(), I found m_pDoc is NULL. If I remove the split views and make CMainFrame::OnCreateClient() like below, then there is no problem.
I've been trying to write my homework assignment (a list of countries, their codes and their capitals) and I've done most of it but I'm stuck at this: I have to open a file, read it and if there are data, add them to the list. So far I've created an element of the structure, queue list, printed the list on the screen and freed the memory. I thought that for reading the file and adding the data I could first open the file (of course) with fopen and after that use a for loop (i=0;i=!EOF;i++) to scan the whole file and fscanf(fp,"%s",result->country),etc in the loop to add the data to the structure of the element and finally insert that element to the queue list. However, when I try to do these operations, I only get to writing the name of the file and the program crashes.
Is it possible to display data from a textfile and also save data in to a textfile, reason being is for me to create back-ups of data into a textfile hidden somewhere in a safe location in the local disk or server in case of database error and failure.
I am trying to add data from a file that would go into a class that would later go into a vector of a class. I'm not really sure how to do it exactly. Here is the code:
Champion_Info.h
#ifndef CHAMPION_INFO_H_INCLUDED #define CHAMPION_INFO_H_INCLUDED #include <vector> #include <string> using namespace std; class Champ_Info {
And I want to make adding,deleting, and searching functions.Something like
Code:
void add();//Add name and address to a file, //and add more to the same file if I want to. void del();//Delete or Change some neighbor's name or address //in the same file(Can I?) void search();//Search name and show detail
So I started to code adding function first, but I don't know that I need to use pointer to code each functions relations, and I don't know how to check that my input's already exists yet. But I started some code below...
Code: void add() { int i=0; FILE *fp = fopen("neighborhood.txt", "at"); if ( fp != NULL ) { do{
I'm having a problem filling a vector from a file. Basically, it is adding an empty element at the end. I'm new to Qt and haven't worked with file streams much so how to stop the stream before it adds the extra element.
But, if I add another element to the vector and write that the file look like this.
//file after adding element 132654 0 02132014 132654 0 02132014 0 0 132998 22 02202014
I have it set to append at the moment so that is why the first line is repeated. I figure the problem is with if(in.atEnd()). I could fix it by deleting the last element right after adding it, but that seems like more of a hack than anything else.
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 am making a multiple quiz program. So everything is working fine, except for the part where i'm trying to add a highscore for each user which is being stored in a binary file. I have added a sample of the program containing the error. This isn't the actual program, which is very long.
class user { //The collection of all info pertaining to the users char user_id[50]; public: int hscore1; user() { strcpy(user_id,"NULL"); hscore=0;
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 need to develop an application in VC++ that will take .WAV files as an input and identify if there is a Gun shot in that wave file. WAVE file with gunshot must be having certain paramaters like frequency, bit rate etc which I don't know right now. But is there a way in VC++ to develop a program that can recognize gunshots by comparing that .WAV file with certain parameters?
Every time I run if(color=="1") it's supposed to add 1 to redTotal. However, every time I run if(color=="1") if get 1 for redTotal every time.
(Write a program that provides the option of tallying up the results of a poll with 3 possible values. The first input to the program is the poll question; the next three inputs are the possible answers. The first answer is indicated by 1, the second by 2, the third by 3. The answers are tallied until a 0 is entered. The program should then show the results of the poll—try making a bar graph that shows the results properly scaled to fit on your screen no matter how many results were entered.)
Code: #include <iostream> #include <string> using namespace std; int main()
