hi,
1. read the structure of msg in detail,
typedef struct tagMSG {
HWND hwnd;
UINT message;
WPARAM wParam;
LPARAM lParam;
DWORD time;
POINT pt;
#ifdef _MAC
DWORD lPrivate;
#endif
} MSG, *PMSG, NEAR *NPMSG, FAR *LPMSG;
wp is pMsg->wPar...
lp is pMsg->lP...
2. maybe yes, i did't check this code. you try to test it.
|
|
|
|
|
hi,
1. for pMsg, there are some other params, just only send/post wp and lp can resolve the problem?
2. ok, i will test it.but cannot now.
thank u again!

I have downdload the the fantastic control named cgfxoutbarctrl,
at http://www.codeguru.com/controls/outbar.shtml[^],now I try to chang the right view of CGfxSplitterWnd(derived from CSplitterWnd).But exception occurs when
runing it and the dialog displays "Unhandled exception in filetitle.exe(MFC42D.DLL):0x0000005 Access Violation".I found the hWnd=??? in the class pointer during debug.
Fllowing is my own code ,please tell me what's wrong with it and how to correct,thanks!!
<br />
void CMySplitterWnd::ChangeView(int row, int col, CRuntimeClass* pViewClass)<br />
{<br />
ASSERT(pViewClass->IsDerivedFrom(RUNTIME_CLASS(CView)));<br />
<br />
CView* pView = STATIC_DOWNCAST(CView, GetPane(row, col));<br />
CFrameWnd* pFrame = pView->GetParentFrame();<br />
ASSERT(pFrame);<br />
<br />
CCreateContext cc;<br />
memset(&cc, 0, sizeof(cc));<br />
cc.m_pNewViewClass = pViewClass;<br />
cc.m_pCurrentDoc = pView->GetDocument();<br />
cc.m_pNewDocTemplate = cc.m_pCurrentDoc ?<br />
cc.m_pCurrentDoc->GetDocTemplate() : NULL;<br />
cc.m_pCurrentFrame = pFrame;<br />
<br />
DeleteView(row, col);
TRACE("Rows=%d,Columns=%d",GetRowCount,GetColumnCount);<br />
VERIFY(CreateView(row, col,
pViewClass,<br />
CSize(0,0),
&cc));<br />
<br />
RecalcLayout();
<br />
CWnd* pWnd = GetPane(row, col);<br />

Hi,
You can use Install Shield.

You can Create one new Setup Project in Visual Studio.

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.
