To add my program into the context menu (when the user right click on excel file). I used the following code:
Code:
public static bool AddContextMenuItem(string Extension, string MenuName, string MenuDescription, string MenuCommand)
{
bool ret = false;
RegistryKey rkey = Registry.ClassesRoot.OpenSubKey(Extension);
if (rkey != null)
{
string extstring = rkey.GetValue("").ToString();
[Code] .....
I used the following function to retrieve the excel file path has been rightclick choose to load the program:
Code:
public static void OpenExcelFileWithEasyForm(string filePath)
{
try
{
string excelFilePath = Path.Combine(Path.GetDirectoryName(filePath), string.Format("{0} (EasyForm){1}", Path.GetFileNameWithoutExtension(filePath), Path.GetExtension(filePath)));
[Code] .....
But I still do not load the excel file into my program by selecting the program from ContextMenu (right click on excel file and choose program). Although if select the path to excel file from the program, the data from excel file is loaded into the program.
I'm still missing something at function OpenExcelFileWithEasyForm(). How to complete this function to load the excel file into my program when selecting programs in ContextMenu.

how to create a context menu but none of them discuss how to actually fetch the selected menu item?
if (e.Button == MouseButtons.Right)
{
ContextMenu m = new ContextMenu();
m.MenuItems.Add(new MenuItem("Font Size 8"));
m.MenuItems.Add(new MenuItem("Font Size 9"));
m.MenuItems.Add(new MenuItem("Font Size 10"));
m.Show(listBoxChecklist, new Point(e.X, e.Y));
//tempString = m.?????
}

I'm trying to build an app, but i don't know which is the best language choice. For starters, the app should be able to:
1. run from context menu
2. when selecting some text from a web browser (ff, ie), that text is captured (preferably not in clipboard) and sent as argument to the program via context menu and the program starts executing...
Is this possible?
e.g. [URL] ....

It is suppose to display the message "This Account ID does not exist" but why do I get "segmentation fault"??I was able to compile and run the program so it shouldn't be a problem of the compiler.
Code:
#include <stdio.h>#include <string.h>
struct Account {
char* Account_ID;
char* Account_Type;
char* AccountOwner_FirstName;
char* AccountOwner_LastName;
float* Balance;

I want to check if there are files present in a directory that match a certain regex, i.e., "reader_contact_info_%d", and if there are, I'd like to get the names of these files, perhaps the number that exist, and then open them and read them.
I could do something via executing an ls command Code: ls reader_contact_info_* but there are performance implications as the current process will suspend while the ls command executes.
I'm not sure how to do this though? It doesn't have to run on Windows, so that's not a problem.

I was wondering how can we know how many items exist in a dialogbox? If there any way that i can get the items ID in a dialogbox by having just the dialogbox's object or handler? Or any way that we can get a dialogbox content by coding.

For the last part of this problem, if player 2 loses the game of hangman, I need to display the letters they did get right. In order to do that, I believe that I need to traverse vector v for the elements that exist in the string hiddenword, and then print those characters that match.
#include <iostream>
#include <cstdlib>
#include <ctime>
#include <string>
#include <vector>
#include <algorithm>
using namespace std;
int letterFill (char, string, string&);

I have a datagridview with many columns. I want a context menu to show up when user right-clicks on the fifth column (column index = 4).
private void dgv_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e) {
if (e.Button == MouseButtons.Right) {
DataGridView.HitTestInfo hit = dgv.HitTest(e.X, e.Y);
if (hit.ColumnIndex == 4) {
contextMenuStrip1.Show(Cursor.Position);
}
}
}
The problem is, the hit.ColumnIndex value is either 0, -1 or 1, no matter where I click. So the condition never met and the context menu never shows up. Why the values 0, -1 or 1?

I need to render content of CRichEditCtrl on device context of some CWnd. This code works ok:
Code:
CDC *dc = wnd->GetDC();
CRect cr;
wnd->GetClientRect( &cr );
dc->Rectangle(cr);
cr.right *= 15;
cr.bottom *= 15;
[Code] ...
The problem is that I want to scale the output. I was trying to send message to my control before blitting:
SendMessage( EM_SETZOOM, numer, denom ).
It scaled the control itself, but the blitted context was still the same size as original content CRichEditCtrl (befeoe scaling). Is there any way to blit/render scaled content of CRichEditCtrl to any device context (screen/paper) ?

I'm writing a class "Property" for a program that manages different types of properties. This is my .h for y base class. I was trying to write a virtual void function to convert different children classes to strings that can be displayed, but Xcode is freaking out.
I had it as:
virtual void toString()= 0;
and it gave me an error message: "Virtual can only exist in non-static member functions" and "field has incomplete type 'void'"
I changed it to:
virtual string toString() = 0;
and the error message didn't change.
Is this an issue with Xcode or did I do something wrong? Even after changing it to string it told me that it "has incomplete type 'void'"....

time_t tim;
time(&tim);

I've been wondering if there's a function or procedure used to know the current video mode. An example of how this was done in Pascal:
function VideoMode : integer;
begin
if (lastmode = BW40) or (lastmode = BW80)
VideoMode := 40
else
VideoMode := 80;
end;
I've been told "conio.h" has a lastmode function, but it doesn't seem to be supported in Dev-C++ and Visual Studio C++. Is there a Windows function to know the number of columns in the current video mode?

I have set a variable as follows:
Point clickLocation = new Point(0, 0);
But when I got to use
clickLocation = Cursor.Position;
It gives me an error of position does not exist? Does WPF not support this way?

I am doing a school project. The project basically is that it records the in and out time of an employee(of an particular company).The employee while checking in or out should enter a unique key generated specially for him so that no one else can check in and out for him.Then referring to the employees position( A worker or a manager or something like that) his total working time each day , for a week and a month is calculated. The company starts at 8 am and ends at 5 pm for 1st shift and for second shift from 3.30 pm to 2.30 am. Plus Saturday and Sunday off. Then after a month the program refers to the working time date stored in a file and calculates his pay(For workers its per hour salary and for managers it aint).
If an employee is consistently late the details are forwarded to the HR account( so that necessary steps are taken).This will support the company log the details of their employees duty time plus give enough detail to take action if someones always late. I'm doing this as a school project and it needn't be of enterprise class and all.. But i want the coding to perform as it should. Also i'm forced to use the old Turbo C++. Now i'm struck in the place where the time of the employees in and out time is logged. This coding does the work
Code:
void main( ) {
clrscr();
char dateStr [9],timeStr [9];
_strdate( dateStr);
cout<<" The current date is "<<dateStr<<'
[Code] ....
I think the second one is better as it not only gives me date but also gives me the day so i can check easily for the weekends. So, how these time functions work.

I'm trying to output only a few files, using regex, from the current directory, this is my main code:
Code:
// main.cpp
{
char * _dir = new char[MAX_PATH];
getcwd(_dir, MAX_PATH);
unique_ptr<CExtractor> _ptr(new CExtractor(_dir));
delete[] _dir;
}
Code:
// CExtractor.cpp
DIR *pdir = NULL;
struct dirent *pent = NULL;
pdir = opendir(_cwd.c_str());
while ((pent = readdir(pdir)) && (pent->d_type != DT_DIR)) {
if (regex_match(pent->d_name, regex(".(in|txt)$"), std::regex_constants::icase)) {
cout << pent->d_name << endl;
}
}
closedir(pdir);
My code is compiled correctly, but when I run my binary, nothings is outputed..here are my files in the current directpory:
aclocal.m4 config.guess config.status depcomp m4 NEWS

autom4te.cache config.h.in configure install-sh Makefile.am src
ChangeLog config.h.in~ configure.ac libtool Makefile.in stamp-h1

Its a code in module of my program, where I need to print current time (HH:MM:SS) at regular intervals.
Code:
#include<time.h>
#include<stdio.h>
//#include<windows.h>
void delay(unsigned int t){ // loop for some delay.
[Code] ....
But when I am running this code I expect this to print difference in time due to delay. But it doesn't enter the delay loop, why ?

I have a program that stores current a low numbers. The Object is to Store the low number every time time one is presented. so say I start the function the first number is the low number. but the trouble im having it once the function is called again it starts over(low number). Is there a way I can keep the function value once the function is called again? Any better way of doing this while keeping function in a class?
double a;
class rff{
public:
void FGH() {
doubleb=0;
cout<< "pick a number"<<endl;
