Hi all,
I have searched several places including message boards and Google, without any result! Have I missed something or am I the first to ask regarding this:
How can I create, or get an already available, invert pen? Which when used for drawing (ex. lines) it inverts all pixel colors it comes in “touch” with. I am not looking for the DrawFocusRect function, but a pen or function that draws an invert line.

Once you get a pointer or handle to a device context, call SetROP2 and pass in R2_NOT as the drawmode.

Could someone please let me know how I can get my CDHTMLDialog to scroll. I have tried "scroll = yes" in the Body tag of the html and setting the scrollbars in the dialog editor itself but niether seems to work. I have another app that scrolls just fine but his one will not cooperate. Any ideas. This must be a common newbie question 
IDE: Visual Studio 2002
Lang: C++.
Project: MFC Dialog Based
TIA.

What the heck is this and why did it fix my problem?
BOOL CAutoDlg::OnInitDialog()
{
SetHostFlags(DOCHOSTUIFLAG_NO3DBORDER);//enables scrolling???
CDHtmlDialog::OnInitDialog();
....
}

CDHtmlDialog::OnInitDialog() calls
SetHostFlags(DOCHOSTUIFLAG_NO3DBORDER | DOCHOSTUIFLAG_SCROLL_NO).
Your call clears DOCHOSTUIFLAG_SCROLL_NO flag and enables scroll bars.

Ok help me out here now ;>
First of all this is only a thought i had and if you think it's totaly stupid, please do say so if you wish :P
Ok, here is the deal.. Im planing on making a type of resource manager, all "resources" should inherit by a class "Resource" that also takes an templated argument for a type...
template <class Type>
class Resource
{
private:
Type *m_Res;
public:
Resource();
virtual ~Resource();
virtual Type * GetResource() { };
virtual operator=(const Type &t) { };
}; // Etc etc
And thus enabling the user to still overload everything given by the base class if it's need for it, so for a texture for instance.
class Texture : Resource<IDirect3DTexture9>
{
public:
int Width;
int Height;
// Etc...
private:
bool Load(string);
// and all the stuff connected to it.
};
and a material
class Material : Resource<D3DMATERIAL9>
{
private:
// lots of strange stuff
public:
// same here
};
So far, i like the model and how i can use it for most stuff that i could call a resource... but here comes the problem, as its templated i cant use the class "Resource" as a "base" class for casting, so in the resource manager i cant just make a std::list<Resource> l; and then push back whatever that comes from resource.
ex:
class ResourceManager
{
private:
std::list<Resource *> m_ResList;
public:
bool Add(Resource *res) {
m_ResList.push_back(res);
}
};
If anyone even takes time to read this post i am soooo wanting ideas about this. Anyone want to help making it maybe better? .. A better way to make it? .. want me to throw it out the window . .whatever as long as you understand what i want to make you are welcome to reply 
(Tired and dont even know how all that came out, if to many dont understand it just ignore it later ... I hope someone does tho

Could anybody explain me, any example very welcome:
I create modeless dialog, as follows:
in myTabControl.cpp // The source code for this class I downloaded from code guru page
void CMyTabControl::Init()
{<br />
m_tabCurrent=0;<br />
m_tabPages[0]->Create(IDD_DLG_TAB1, this);<br />
m_tabPages[1]->Create(IDD_DLG_TAB2, this);<br />
<br />
m_tabPages[0]->ShowWindow(SW_SHOW);<br />
m_tabPages[1]->ShowWindow(SW_HIDE);<br />
SetRectangle();<br />
}
I call Init() function in:
In Stp2View.cpp
void CStp2View::OnInitialUpdate()
{<br />
CFormView::OnInitialUpdate();<br />
GetParentFrame()->RecalcLayout();<br />
ResizeParentToFit();<br />
<br />
m_tab.InsertItem(0, _T("Table1"));
m_tab.InsertItem(1, _T("Table2"));<br />
<br />
m_tab.Init();<br />
}
My question is:
how can I update data in IDD_DLG_TAB1 Form, for example
in Stp2View.cpp
void CStp2View::OnMoveToNextRecord()<br />
{<br />
.....<br />
CString str = "test update data";<br />
UpdateData(TRUE);
ASSERT(::IsWindow(m_hWnd));
....<br />
((CDlgTab1*)tab.m_tabPages[0])->UpdateData(FALSE)
}
Thanks a lot ...

I found that i need to override PreTranslateMessage to trap events .
if(pMsg->message==WM_KEYUP ){
CString text;
text.Format("Key params %d ",pMsg->wParam);
AfxMessageBox(text);
return true;
}
I need to trap a sequence of ALT-CTRL-E ? How can I do this ?
|
|
|
|
|
If you're looking for all 3 keys to held down at the same time, just look for one of them (like "E") with PreTranslateMessage, then check keystate of others with GetAsyncKeyState. VK_CONTROL is virtkey for Ctrl, and VK_MENU is virtkey for Alt.

I have a number of modeless dialog in my MDI applicaion.
When I try to open multiple dialogs and close, sometimes
the application fails. what is the proper way to close a
modeless dialog if I open the dialog like the following.
at the moment I make another function in dialog class called
closedialog and call protected function OnClose() any I was
thinking of deleting the pointer that was new at the top of
line. I am not 100% sure about it.
Any help is appliciated.
if( ! p_MyModelessDlg )
{
p_MyModelessDlg = new CMyModelessDlg;
}
if( pDoc -> b_Data == TRUE )
{
if (!::IsWindow( p_MyModelessDlg -> GetSafeHwnd() ) )
{
p_MyModelessDlg -> Create(IDD_MYMODELESS, this);
}
p_MyModelessDlg -> GetData();
p_MyModelessDlg -> ShowWindow(SW_SHOW);
p_MyModelessDlg -> b_OpenStatus = TRUE;
}

You need to override the beahviour of the PostNcDestroy() - in this method
FIRST call the super classes' PostNcDestroy()
and then
delete this;
You may need some way to tell your app the dialog is closed (you might put this in your PostNcDestroy impl.

I need to do this in the console, how can you open a file from the program and then go to line_. Then depending on what was on that line output something else. I would appreciate maybe even a website. AI thing ya know.

Using MFC:
CStdioFile file(...);
CString strLine;
int nLine = 17;
while (nLine >= 0 && file.ReadString(strLine) == TRUE)
nLine--;
file.Close();
TRACE("This is the 17th line: %s\n", strLine);

I need to disable the tool bar button in my application (MFC).
kindly advise.
note :already tried using CToolBarCtrl::EnableButton().It did not work
|
|
|
|
|
Hi,
You have to use the OnUpdate command for the tool bar button. For example say I had a button called delete in which I had a function called OnDelete().
Updating the toolbar button would work like this:
OnUpdateDelete(CCmdUI* pCmdUI)
{
pCmdUI->Enable(FALSE);
}
That would disable it. Obviously you can pass true or false into the enable function. That's all there is to it.

Hello,
I am trying to download files from the internet. Currently I use the Windows API functions InternetOpen, InternetOpenURL, InternetReadFile, etc.
HINTERNET hFile;
DWORD dwRead = 1;
BYTE pHttpBuffer[TR_BUFFER_SIZE];
hFile = InternetOpenUrl(m_hConnection, TR_URL, NULL, 0,
INTERNET_FLAG_RELOAD, 0);
if(hFile == NULL) return false;
while(dwRead != 0)
{
if(InternetReadFile(hFile, pHttpBuffer, TR_BUFFER_SIZE, &dwRead) == TRUE)
{
if(dwRead != 0)
{
_ParseBuffer((char *)pHttpBuffer, TR_BUFFER_SIZE);
}
}
else dwRead = 0;
}
InternetCloseHandle(hFile);
The _ParseBuffer function does something with the buffer, it doesn't matter here.
When I start the program, it sends out some bytes (I see this with personal firewall monitor) and waits about 10 seconds for the answer. I don't know what I am doing wrong. It's not the internet server.
Do you know any other method than this for downloading files? I cannot use URLDownloadToFile, nor can I use MFC.
Thanks in advance
Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Hi all and sorry for my English,
I writed this code very time ago.
bool InetStartup()
{
g_hInternet = InternetOpen( INTERNET_OPEN_TYPE_PRECONFIG,
NULL,
NULL,
NULL,
0 );
HINTERNET hSession;
DWORD dwContext = 0;
hSession = InternetOpenUrl( g_hInternet,
_T("http://www.stratos-ad.com/gfx/home_top_01.gif"),
NULL,
0,
0,
dwContext );
char pBufferData[1024];
DWORD dwBytesRead;
DWORD dwBytesWrite;
HANDLE hFile = CreateFile( _T("Dibujo.gif"),
GENERIC_READ | GENERIC_WRITE,
0,
NULL,
CREATE_NEW,
FILE_ATTRIBUTE_NORMAL,
NULL );
while( InternetReadFile( hSession,
pBufferData,
1023,
&dwBytesRead ) )
{
pBufferData[dwBytesRead] = 0;
OutputDebugString( pBufferData );
OutputDebugString( _T("\n") );
if( dwBytesRead == 0 ) break;
WriteFile( hFile, pBufferData, dwBytesRead, &dwBytesWrite, NULL );
}
CloseHandle( hFile );
return true;
}
bool InetStop()
{
InternetCloseHandle( g_hInternet );
return true;
}
I hope help you.
Byes
