Thanks a lot!
I'm aware of the virtual memory and physical memory concepts. I just got
confused by the statement that process A and process B both have acess to virtual memory at 0x12345678, because my understanding is that the system
uses the virtual memory space allocated to the process to verify whether a memory access is valid and an Access Violation would be raised if it's not.
Is my understanding wrong?
Thank you very much for your help!

I want to draw a line/rectange(normal CPaintDC functions) in a Dialog?

Add a handler for the WM_PAINT message (OnPaint) and have a blast.

Maybe you're right, but I'd say WM_ERASEBKGND is the place to go.

I'm looking to have my app monitor another app (Internet Explorer) and respond to any dialogs( warning, error, connection ) that appears so the user doesn't have to. I have started studying up on hooking, but I wanted to see if that is the correct approach.
As a note, my app starts the IE instance that I want to monitor.
Thanks for any help or suggestions.

a better approach for specifically hooking to internet explorer is to use Browser helper object

Hi,
I have already posted this message but somebody told me that it's wasn't clear enough.
Here is my problem.
I have a MDI App that contain a dialogbar(modeless dialog). On my dialog, I have a bitmap. I want my bitmap to have transparency on some part of it so that I can see the default color of my App in those part.
In my Mainframe class, I have a variable named m_wndDlgBar from CDialogBar and my dialog is created in the ressource editor.
I tried to use
LoadMappedBitmap(IDB_LOGO, 0, &color, 1)
with
COLORMAP color;
color.from = RGB(0,0,0);//color to be changed
color.to = COLOR_WINDOW;//default color
thanks!

I found out that the location of a #import statement matters.
Does the location of #includes matter? I have them as shown on rted. Are they in the right place in the .h file? Should they be moved above or below the #if s?
#if !defined(AFX_SEARCHVIEW_H__4E3DD48E_02D6_42F4_88D5_81E8ECCC08B2__INCLUDED_)
#define AFX_SEARCHVIEW_H__4E3DD48E_02D6_42F4_88D5_81E8ECCC08B2__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
#ifndef __AFXEXT_H__
#include <afxext.h>
#endif
<code>#include "mainfrm.h"
#include "childfrm.h"</code>
class CSearchView : public CFormView
Thanks
Appreciate your help,

In your case, they should be after the #if's
don't put #include in .h files unless absolutly necessary, for example class inheritance, and non-pointer class objects.
#include "BaseClass.h"
#ifndef _SOMEOBJECT_H_
#include "SomeObject.h"
#endif
class MyClass : public BaseClass
{
SomeObject m_SomeObject;
};
the declaration of m_SomeObject could/should be replaced by
#include "BaseClass.h"
class SomeObject;
class MyClass : public BaseClass
{
SomeObject* m_SomeObject;
};

Gosh! I thought I was doing something wrong when I would put #includes in the cpp file!!! SO I started putting them in the .h!
So If I have a A.h and a A.cpp pair with a #include B.h in A.cpp, and I go and do a #include A.h in file C.cpp, everything will work out right?
Thanks
Appreciate your help,

Why should we put our #include's in .cpp files rather than .h files? (I'm a student, not a programming expert)

To remove the dependencies of objects.
if in class A I have an Object O and is declared directly in the class declaration, I need to have the #include for it in the .h file.
#include "O.h"
class A
{
O m_o;
};
so, everytime that O changes ( the file is changed ) , a.cpp. and every other files that include a.h will be recompiled.
but if I have
class O;
class A
{
O* m_pO;
};
there's no dependencies in the .h file.
For small projects, it's not that important whether you put #include in the .h files, but for large projects, is can be costly.

Alright, I've looked all over the friggin place, and I'm starting to get frustrated.
All I want to do is have a control that contains rendered HTML from local text that I feed it. I won't be loading anything from the web. Just from text strings in memory.
I've tried the CHtmlView, but on creation it seems to have no document in it. After I Navigate2() some page, then I can call GetDocument() and start replacing the internal HTML. But I don't want to have to Navigate2() anywhere.
Am I completely loopy for wanting to do this?
All I need is a simple control that renders HTML from a string input. Any recommendations?

If using the CHtmlView, you need to Navigate to "about:blank" first, then wrench around the document. Or, my personal favorite, go to QHTM[^] and use his control.

I'll try that "about:blank". Sounds like that's what I need. And as to wrenching around the document, is that the way to do it?
CHtmlView::GetDocument() -> IDispatch
IDispatch->QueryInterface -> IHtmlDocument3
IHtmlDocument3->documentElement -> IHtmlElement
set IHtmlElement->innerHTML
Seems convoluted.
On the other hand, QHTM looks like it solves my problem quite nicely. It will even let me do my internal navigation without having to host a custom pluggable protocol for IE...
Thanks!

No, you don't need to wrench to hard.  I have some code that does it, but it boils down to getting the IHTMLDocument2 interface, then calling the Write method. Thats about it. My code has some other useful functions like setting the background color, overriding the opening of new windows, and so forth, but to just display a document thats all you need to do.

Perfect. I knew there would be an easier way. Of course having to create a safearray for a single string seems a little extreme, but I'll give it a go. 
Thanks for your help!

Yes, QHTM looks quite handy. I'm undecided as of yet whether or not I need the full IE control...
I saw the XHTMLStatic control, but it's too lite for me. I need pretty much full HTML compliance.

BYTE Buffer[256] = {1, 2, 3, 4, 5, 6};
LONG nRetVal = ERROR_SUCCESS;
HKEY hKey = 0;
nRetVal = ::RegOpenKeyEx(HKEY_CURRENT_USER, _T("Software\\MyCompanyName"), 0, KEY_ALL_ACCESS, &hKey);
if(nRetVal != ERROR_SUCCESS)
return ::RegSetValueEx(hKey, _T("My Binary Field"), 0, REG_BINARY, Buffer, sizeof(Buffer)/ sizeof(BYTE));
return nRetVal;

Do you know any function to return if the app is running from a server or from the local machine ??
Thanks,

what kind of application, environment, technology?
In short what info do you have, and what exactly do you want to know?
|

Is a Windows MFC Aplication, dialog based. I want to know when the app is running from another machine (server in a LAN) or from a local machine (the app located in the same machine that it is running).
Then, I need to make my app for don't run from a server, only from the local machine. Ok ??
Any idea ??
