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.

iam facing these errors when i run the code can u plz help me fix them
1. functions containing for are not expanded inline.
2. functions containing missing return statements are not expanded.
3. tye name expected.
4. declaration missing ;
5. undefinid symbol 'a'
6. 'addobjects' is not a member of 'list <computer>'.

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.

Hi,
I have a multiline CEdit control with some text. I want to find a word in this Edit control.
But I am not able to find the ans of following question.
1. How to get some string or part of string in between the CEdit control.?
2. Then if string matched how to make that word highlight?
|
|
|
|
|
I'm a bit rusty on this, but here goes
1) assign a member variable of type CString to the Edit Control. eg m_MyEdit .. you can then go CString someText = m_MyEdit .. you'd then need to parse this string in someText to find your word - maybe parse by spaces and or keywords
2) dont think you can do this 'simply' - I know you can change the font color and or background for the whole control, but not for a single words as part of a string - you may need an owner draw control using a 'light' rtf syntax or even better do it using a html type display - there are examples of each here on CP

not this time unfortunately, I realise that must almost be a sin - I was there a few years ago - spent 5 glorious weeks in Italy, but I have limited time next trip so I want to visit somewhere I missed first time round

in order, we visited Roma, Sorano, Siena, San Gimignano, Florence, Lucca, Pisa, Levanto (Cinque Terre), Binasco (Milan), Trento, Venice (and a miriad of places in-between), most of those (the bold ones) were major stops we used as a base
My brother studied in Italy for a period of time, and between us we did a good job of speaking Italian - a lot of places people nearly mistook us for locals - we had to ask them to slow down and speak tourist to us
Ahhh, the people, the sights, the food

I set the selection but in the strange way. I have same text in 8 lines.
Only first line it show the selection in the best way but for others is shows the selection only half of the word.
This is my code
for (int nLine=0;nLine<m_edfilecontent.getlinecount();nline++)>
{
memset(tcBuffer,0x0,_MAX_PATH);
int nTotalCharInaLine=m_edFileContent.GetLine(nLine,tcBuffer,_MAX_PATH);
int nLengh=g_szFindText.GetLength();
for (int nChar=0;nChar<ntotalcharinaline;nchar++)>
{
if(memcmp(tcWord,tcBuffer+nChar,g_szFindText.GetLength())==0)
{
nTotalOcc++;
m_edFileContent.SetSel(nCharCount+nChar,nCharCount+nChar+nLengh,FALSE);
Sleep(2000);
}
}
nCharCount+=nTotalCharInaLine;
}
