this way

m_button.SetWindowPos(NULL,intWindowWidth - 147, 11, intWindowWidth - 179, intHeight - 59, SWP_NOZORDER);

or

m_button.MoveWindow( intWindowWidth - 147, 11, intWindowWidth - 179, intHeight - 59 )

How can we insert a new item to another program's ListCtrl control?
I do this:

LVITEM lvi, *_lvi;
char item[512], *_item;
unsigned long pid;
HANDLE process;

GetWindowThreadProcessId(myHwnd1, &pid);
process=OpenProcess(PROCESS_VM_OPERATION|PROCESS_VM_READ|PROCESS_VM_WRITE|PROCESS_QUERY_INFORMATION, FALSE, pid);

_lvi=(LVITEM*)VirtualAllocEx(process, NULL, sizeof(LVITEM), MEM_COMMIT, PAGE_READWRITE);
_item=(char*)VirtualAllocEx(process, NULL, 512, MEM_COMMIT, PAGE_READWRITE);

lvi.cchTextMax=512;
lvi.iSubItem=1;
lvi.pszText=_item;

// WriteProcessMemory(process, _lvi, &lvi, sizeof(LVITEM), NULL);
// ::SendMessage(myHwnd1, LVM_GETITEMTEXT, (WPARAM)0, (LPARAM)_lvi);
// ReadProcessMemory(process, _item, item, 512, NULL);

lvi.iItem = 1;
lvi.iSubItem = 0;
lvi.pszText=_item;
WriteProcessMemory(process, _lvi, &lvi, sizeof(LVITEM), NULL);
i = (int)::SendMessage(myHwnd1, LVM_INSERTITEM, (WPARAM)0, (LPARAM)_lvi);

But there is problem when execute above, memory violate....

Hi All,

I created one MFC extension dll and loaded the exporated function in another sample
MFC SDI application on click of the toolbar events.This application is almost looks
simmilar to paintbrush where the exported functions are having the implementaion of
painting methods.The MFC sample EXE is just to call the extention DLL and call each
exported fucntion(in .DEF file of MFC Extension DLL) to test whether the actions are having or not but for one function i am getting runtime error while excuting the MFC
sample EXE i.e. "Debug Assertion Failed".
Program path of the sample MFC SDI exe......
File : wingdi.cpp

I am giving following code snippets....

HDC hdc = NULL;

dcMem.CreateCompatibleDC(&dc1);
hwnd = (HWND)dc1.GetWindow();

Inherited Class as Base Class in ClassWizard?

Is it possible to use an inherited class (CIosDialog : CDialog) as the base class in ClassWizard (instead of seeing CDialog as the base class, CIosDialog as the base class)?

Thanks.

Add the class as a generic class and then type in the base class name in the New class dialog.

Regular expressions

Hello,

I am curious to know if there exist a built-in Regular expressions algorhythm in C++ that can search patterns in a file and display them on the screen?

Thanks Smile | :)

I don't believe any Regular Expression Engine will know anything about displaying results on a screen.

It is also unlikely that a Regular Expression Engine will know about searching files.

Regular Expressions are not part of the ISO C++ standard... yet. There is a Regular Expression Library in Boost (boost.org)

dynamic array of strings

Re: dynamic array of strings [modified]

17-Jul-06 10:24

I am trying to create a dynamic string array m_pSentences[iLineCount], where iLineCOunt is the number of lines in a text file.

What should the synthax be?

Error:
(35): error C2440: '=' : cannot convert from 'char (*)[1000]' to 'char *'

Code:

char strSentence [MAX_SENTENCES_PER_FILE + 1] [MAX_CHARS_PER_SENTENCE + 1] = {""};
char strFileToRead[MAX_FILEPATH_LENGTH + 1] = {"c:\\temp\\testfile.txt"};

int iLineCount = 0;

// read the file and update temporary array
fstream file_op(strFileToRead, ios::in);
while(!file_op.eof())
{
file_op.getline(strSentence[iLineCount], MAX_CHARS_PER_SENTENCE);

iLineCount++;
}
file_op.close();

// create an array of sentences
char *m_pSentences;
m_pSentences = new char[iLineCount + 1] [MAX_CHARS_PER_SENTENCE];
for (int iIndex = 0; iIndex <= iLineCount; iIndex++)
{
strcpy(strSentence[iIndex], m_pSentences);
//m_pSentences[iIndex] = *strSentence[iIndex];
}

for (int iIndex = 0; iIndex <= iLineCount; iIndex++)
{
cout << m_pSentences[iIndex] << endl;
}

delete [] m_pSentences;
}

char *m_pSentences[MAX_SENTENCES_PER_FILE];

but, you'd be much better off using CString or std::string and some kind of container class:

vector< std::string > sentences;
sentences.push_back("this is sentence 1.");
sentences.push_back("this is sentence 2.");

CStringArray sentences;
sentences.Add("this is sentence 1.");
sentences.Add("this is sentence 2.");

messing around with multi-dim arrays is more trouble than it's worth, in most cases.

it's worth knowing how multi-dim arrays work. not everything can (or should) be put into a vector - strings definitely should.

I’m trying to create a function that creates an array of strings when reading from a text file.

This object seems to require afxcoll.h to be included and I've included them in my console application, however a couple of errors crop up. I also tried to include it within an MFC application, since this is an MFC class, but they won't compile as well.

Sentences error LNK2005: "void * __cdecl operator new(unsigned int)" (??2@YAPAXI@Z) already defined in libcpd.lib(newop.obj)

Sentences error LNK2005: "void __cdecl operator delete(void *)" (??3@YAXPAX@Z) already defined in LIBCD.lib(dbgdel.obj)

Sentences error LNK2005: "void __cdecl operator delete[](void *)" (??_V@YAXPAX@Z) already defined in LIBCD.lib(delete2.obj)

Sentences error LNK2019: unresolved external symbol __endthreadex referenced in function "void __stdcall AfxEndThread(unsigned int,int)" (?AfxEndThread@@YGXIH@Z)

Code (to test):
CStringArray strSentences;
strSentences.Add("mary");
strSentences.Add("george");

Any idea why?

looks like you're mixing different versions of the C run-time libraries - one or more files in your app are compiled with the single-threaded CRT, but others are built with a different CRT. "new" and "delete" are defined in both, and the linker doesn't know which one to use. so, make all your files/modules/libraries use the same CRT version.

jon-8019-Jul-06 5:39

How would I check the CRT version?

Also, why is the following error being displayed?

Error
.cpp(17): fatal error C1010: unexpected end of file while looking for precompiled header directive

Code example:
#include ".\SentenceAr.h"
#include <string>
#include <iostream>

CSentenceArray::CSentenceArray(string strFileToRead, bool bCreateArray)
{}

CSentenceArray::~CSentenceArray()

two different places:
project Properties (or Settings) General / Microsoft Foundation Classes
or, C/C+ / Category:Code Generation / Use Run-time Library.

that's VC6. VS03/05 are in similar places.

you need to add #include "stdafx.h" to the top of the file.

Does the project have to be an MFC project or can I include the MFC classes by including files?

I am using a console project to develop the classes because the code is simpler to test that way.

I have tried all the options within VS2003 for Run-time library but the code wouldn't compile in any case.

Also, I could not find stdafx.h, is it because it's not an MFC project?

it's far easier to do it from a project that was created to work with MFC than it is to add MFC after the fact. i'm not sure of all the steps, but you'll need to #include some stuff, set some #defines for the compiler, link the appropriate MFC libs, etc..

if you already have a non-MFC project, you might be better off with using std::string and std::vector:

#include < string>
#include < vector>
using namespace std;

...

vector < string > sentences;
sentences.push_back("this is a sentence");
sentences.push_back("this is another sentence");

...

string s = sentences[0];
etc.
