Hi folks, I'm hoping that someone out ther can help this confused MFC newbie 
I'm updating some old MFC code which implements a web browser inside an application (using a class derived from CHTMLView). The html pages I want to load into this browser need to know whether they are running inside the application or in a normal browser (so I can display different content).
I was wondering if it would be possible to set a property of some kind (when the CHTMLView is created) which I can pick up in the html using JavaScript (in the same way as the browser name / version etc), so that it can determine what to display.
Anyone know if it's possible, and if so, how I do it (a web search has revealed very little info on the subject).
Thanks,
Iain

Yes, and maybe no 
When you have loaded a document you may interact with it using the IHTMLDocument2 interface. This way you can add your own kind of properties, say for instance a JavaScript snippet. Trouble is, in your case if I understood you correctly, this will only work once the document is fully loaded, and at that time the original HTML is already displayed, which is probably not what you want. AFAIK, there is no way to control the HTML stream from a web server to the WebBrowser control, unless you make your application act as a HTML proxy server, modifying data as it comes along.
Another solution would be to set up a socket connection to a web server yourself, modify the file, and store it on disk. Load that file into your CHTMLView.

Thanks, I think I have this sorted now. I'm getting OnDocumentComplete to write out a cookie, which the html looks for via a bit of Javascript, (and alters it's content accordingly). Seems to work great

Hi all,
Is there a way to retrieve the bounding rectangle of a popup menu?
Thanks!
|
|
|
|

You could do this in the menu's parent window by handling the WM_MEASUREITEM message and calling the base class version from there. Take a look at the base class's return value and you will be able to work out how big the menu was when it was displayed.
Not sure how to get it before its displayed.

whenever the selection in the list changes this function gets called:
void CSelectReport::OnLvnItemchangedComplist(NMHDR *pNMHDR, LRESULT *pResult)
{
LPNMLISTVIEW pNMLV = reinterpret_cast<lpnmlistview>(pNMHDR);
TRACE("selection = %i\n",m_lstCompanies.GetSelectionMark());
*pResult = 0;
}
however it always returns the item which was just unselected, not what was just clicked on.. its like its always lagged one step behind, which makes it imposible for me to update enabling/disabling of items based on the selection.. can someone please help me understand a way to correct this eroneous microsoft control/event handler?
message map:
ON_NOTIFY(LVN_ITEMCHANGED, IDC_COMPLIST, OnLvnItemchangedComplist)
plz tell me someone else is familiar with this problem! thanks!

"help me understand a way to correct this eroneous microsoft control/event handler"
I can try to help you understand, but there is no "correction". This is not erroneous behavior. It is the way its supposed to work (read MSDN). From your description you are using the wrong event. You might want to try LVN_ITEMACTIVATE.
Good Luck,
Bill

Hi,
It's possible to draw text using Himetric ?, Or should I make the conversion LPtoDP to draw the text ? ( I have problems with the DP, because it changes from a printer to the screen, and...).
Thanks, Greetings

You should be able to DrawText in HIMETRIC, but you will need to take into account the different DPI of different devices.

Is there anyone here who's used the monthview control in a dialog based application who can help me out with the problems I'm having (Using "Microsoft MonthView Control 6.0 (SP4)" using MFC and Visual C++ 6)
I'm not sure if either I'm doing something very wrong, or just this control is full of bugs.
Here are my problems:
1) If I display all 12 months, the days in the last month don't get displayed bold (they get set and unset correctly, and if I change the view to display that month anywhere bar the last displayed month it works fine) - My workaround to this is to just display 9 months and make the user flip back and forth to see the whole year (I predict complaints..)
2) The control grabs focus, meaning if I click on a date, then click on a button on the dialog, it just selects that button rather than clicking on it (1 click to deselect the monthview control, and a 2nd to actually click on the button I clicked on)
3) If I call my function that makes the days bold (using SetDayBold) from my OnInitDialog, the days don't get set bold. If I call it from a mouse click event then it works fine.
I've searched MSDN and found a VB workaround to problem 2, but it wasn't much help to me using C++
Any help will be much appreciated

hello people,please read carefully.
I have a situation with someclasses : X,M,S,E and some structures : A,B,C like this.
class X is autonomous.(i dont know the correct word)
class E has variables of type class X,structures A,B and C.
class X has an pointer of type E(later becomes an array and still later destroyed)
class M:public X
class S:public X
M has a pointer of type S.(later becomes an array and still later destroyed)
now,
all these mean class M has class E(and hence part of itself and S-so twice itself ) due to inheritence.I have to store class in list.
two questions.
1.is CList safe?
2.where can I possibly leak memory.

Uff... you're giving little information to know whether you will encounter memory leaks or not. A distinction has to be made between having (the "had" object is a member variable of the "haver") and owning (the "owner" has a pointer to the "owned"). In the second case, you have to consider what will hapen when objects are copied:
M m1;
...
M m2=m1; Are you duplicating the owned objects of m1? If not, then you will probably run into memory problems, as both m1 and m2 think they own the same objects of type S. You got to think out very carefully these issues, as CList implicitly will make copies of objects contained.

Hi,
can I test list-Box Styles (e.g. LBS_OWNERDRAWVARIABLE) and make sure it is set? Thats better then trusting in a user who sets properties in a dialog resource. Where do I handle this?

|

I tried CListBox::OnCreate, it is never called. I'm stuck.
|
|
|
|

Try PreCreateWindow

nope, is never called for a CLlistBox derived class

Hi All, Can anyone help with this? I'm now totally confused by conflicting articles....
I have a 16Bit DLL that I need to call from a VC++ 6.0 32Bit application. The DLL cannot be recompiled (and it will have a short life anyway).
The 32Bit application needs to run on Windows 9x / NT / 2000 /XP. My understanding is that I need to use the Generic Thunk for this - Is this correct? Is so how? I can find lots of examples of 16Bit calling 32Bit but not the other way around (and would'nt that be the more popular thing to do?) - Or is it so obvious that I am missing the point!
The functions in the 16Bit DLL have been declared as below:
int FAR PASCAL __export files_pack( char *, char *, unsigned, unsigned *, long );
int FAR PASCAL __export files_unpack( char *, char * );
int FAR PASCAL __export split_pack( char *, char *, unsigned *, long );
Does it make any difference because they use the PASCAL calling convention?
HELP PLEASE BEFORE I EXPLODE!
Regards
Kevin.

Thanks, but my confusion continues....

A generic thunk supports all the platforms I require, and does not require the thunk compiler?
Am I any closer?

Kevin.

A generic thunk is for 16 bits apps calling 32 apps and not the opposite .
Win95/98 supports flat thunks that permits a 32 app call a 16 bits app, this is what you want, I presume ?
Win NT/2000 doesn't not support Flat Thunks at all, so you must devise your form of IPC(Interprocess Communication Mecanism) . For instance doing your stub dll between the 16 bits dll and your code.

See this article on MSJ
Nerditorium
It explains that the _stdcall aka PASCAL convention used causes some funky code to be used , since with _stdcall , the calle must clean the stack , not the caller when using _cdecl call convention.

Hi People, so near yet so far.......
Can anyone help me further with this?
I compiled my .ASM modules for the 16Bit DLL, hunted around until I found my MASM disks, compiled the .OBJ, created a 32Bit DLL Stub but now I'm stuck on the linking. Below is the output from the compiler, I assume this has something to do with name mangeling? - Any suggestions?
--------------------Configuration: ThunkDLL2 - Win32 Debug--------------------
Linking...
thk32.obj : warning LNK4033: converting object format from OMF to COFF
ThunkDLL2.obj : error LNK2001: unresolved external symbol "int __stdcall pack_ThunkConnect32(char *,char *,void *,unsigned long)" (?pack_ThunkConnect32@@YGHPAD0PAXK@Z)
Debug/ThunkDLL2.dll : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
ThunkDLL2.dll - 2 error(s), 1 warning(s)

_stdcall mangles names , so normally prefixes a underscore to the functions adds a @ and puts in the name the total bytes of the arguments , and something more e.g :
pack_ThunkConnect32 function uses 4 arguments , so it uses 16 bytes(?) so the calle knows the amount of memory that must pop from stack to clean it .
A fast way to see the name is using quickview utility that comes with windows , and view the mangled name on the exports table ?
