|
|
|
|

If you have sample of MSDN(I dont remember which version) it has an example for it when you run that example it shows to you a list(listbox) of frequencys and resolutions.

Hi,
You can use Install Shield.
or
You can Create one new Setup Project in Visual Studio.
The price of anything is the amount of life you exchange for it.
Thanks and Regards.

Hello,

I 'Clean' the application & then Rebuild it, then also
this problem continues. Also I delete the 'Debug' folder from the current directory
& then Rebuild application then also that problem is not solved.
Plz give me solution.
Thanks in advance.

All,
When I install my Win32 Service using CreateService() I am utilizing a TCHAR string (szPath) to input the full path to the service executable. However, when the service is installed instead of inputting this path to the executable it is inputting the path to the service installation executable that this code resides in.
Can someone explain to me why this would be happening?
Thanks
TCHAR szPath[MAX_PATH] = (L"\"C:\\Program Files\\Temp.exe\"");
TCHAR szStartName[50] = (L"Domain\\User");
TCHAR szStartNamePassword[50] = (L"**********");
schService = CreateService(
schSCManager,
SVCNAME,
SVCNAME,
SERVICE_ALL_ACCESS,
SERVICE_WIN32_OWN_PROCESS,
SERVICE_AUTO_START,
SERVICE_ERROR_NORMAL,
szPath,
NULL,
NULL,
NULL,
szStartName,
szStartNamePassword);

Please help me use this to create a function that will find the minimum spanning tree. I am unsure of how to use the findEdge function to find edges that I can measure their weights for to find the minimum tree. Please help. Hi this is the code for a graph from my book:
#ifndef EDGE_H
#define EDGE_H
class Edge
{
public:
int v, w, weight;
Edge(int firstVertex, int secondVertex, int edgeWeight)
{
v = firstVertex;
w = secondVertex;
weight = edgeWeight;
}
};
#endif
#ifndef GRAPH_H
#define GRAPH_H
#include <vector>
#include <list>
#include <map>
#include "Edge.h"
using namespace std;
class Graph
{
public:
int numVertices;
int numEdges;
vector<map<int, int> > adjList;
Graph(int n);
int getNumVertices() const;
int getNumEdges() const;
int getWeight(Edge e) const;
void add(Edge e);
void remove(Edge e);
map<int, int>::iterator findEdge(int v, int w);
};
#endif
#include "Graph.h"
Graph::Graph(int n)
{
map<int, int>element;
adjList.assign(n, element);
numVertices = n;
}
int Graph::getNumVertices() const
{
return numVertices;
}
int Graph::getNumEdges() const
{
return numEdges;
}
int Graph::getWeight(Edge e) const
{
return e.weight;
}
void Graph::add(Edge e)
{
int v = e.v,
w = e.w,
weight = e.weight;
adjList[v].insert(make_pair(w, weight));
adjList[w].insert(make_pair(v, weight));
numEdges++;
}
void Graph::remove(Edge e)
{
int v = e.v,
w = e.w,
weight = e.weight;
adjList[e.v].erase(w);
adjList[e.w].erase(v);
numEdges--;
}
map<int, int>::iterator Graph::findEdge(int v, int w)
{
map<int, int> m = adjList[v];
map<int, int>::iterator iter = m.find(w);
return iter;
}

the algorithm and code is explained in many papers. Just google it.
the next thing is that, if this is not your homework, you can use
Boost Graph Library. It supports both Kruskal and Prim's algorithms.

I wouldn't expect much help with a question like that.
Why not tell us what kinds of problems you are having with this code?
That'd be a good start.

I tried your code on a visual studio 2005 compiler and it is compiling fine.

It's one thing asking for help - it's another thing expecting us to do your job for you.
You don't read the posting guidelines, so your quoted code is just a slab of text I have no intention of reading.
You don't give any actual errors.
In a reply to another reply, you give some example errors - which sound like things you can fix yourself.
"If a function is missing return..." Then [bleep]ing fix the code so it isn't missing a return!
"...doesn't expand inline". 1/ so what? the compiler is free to make judgements. inline is only a recommendation. 2/ How do you even know it doesn't? 3/ From memory, inline expansion is not done in debug mode.
Also, even if you get the code to compile, that's no reason to say it "wrkz". We don;t know your requirements, so we can't fix all errors.
I wish you luck with your debugging,
Iain.

Hi all,
I'm a beginner and have a beginner question. I want to create a WinForm in C++. I created a Win32 Console Application in VS2008 and write these codes to create a WinForm (They're exactly what I saw in my ebook):
#include "stdafx.h"
#include "windows.h"
INT WINAPI WinMain(HINSTANCE hInst, HINSTANCE, LPSTR, INT)
{
WNDCLASSEX wc = {sizeof(WNDCLASSEX), CS_CLASSDC, MsgProc, 0L, 0L
GetModuleHandle(NULL), NULL, NULL, NULL, NULL,
TEXT("TEST"), NULL};
RegisterClassEx(&wc);
HWND hWnd = CreateWindow(TEXT("TEST"), TEXT("TEST"),
WS_OVERLAPPEDWINDOW, 100, 100, 512, 512,
GetDesktopWindow(), NULL, wc.hInstance, NULL);
}
What is MsgProc? I have error on this line. error C2065: 'MsgProc' : undeclared identifier.
Thank you in advance.

That code has nothing to do with "WinForms" - whatever "WinForms" are (?).
That's basic window creation, and it's pretty much the fundamental concept
in Windows programming.
I would strongly suggest studying at least the windowing overviews here:
Windowing[^]
especially the sections Windows, Window Classes, Window Procedures, and Messages.
The Window Procedures section will explain what the MsgProc parameter is.
It's not difficult to understand, but it is essential knowledge for effective
Windows programming

Seems you've started learning SDK style win32 programming. Well, I recommend you to read "Talk to me like I'm a 3 year old!" programming series by GameTutorials at first. Check it here[^].
Once you finished reading it, you'll find out the answer for your problem, yourself!
Regards,
Jijo.

Thanks Jijo. I'm reading your link. I wonder what are those question marks (�) for? (Maybe I don't know the page Encoding!)

Me too had the same problem. It could be character encoding problem as you said.
