Hi all,

I am using IE6.0 and its crashing many times, When i debug iexplore.exe it using MSVS.

I am getting assembly code as below

77F82D5D je 77F82D70
77F82D5F or ecx,0FFFFFFFFh
77F82D62 xor eax,eax
77F82D64 repne scas byte ptr [edi] <- cursor is at this point
77F82D66 not ecx
77F82D68 mov word ptr [edx+2],cx
77F82D6C dec ecx
77F82D6D mov word ptr [edx],cx
77F82D70 pop edi

and the stack window shows
NTDLL! 77f82d64()
// other stuff.

Can someone help me in tracing the problem. and how to extract information from this

Thanks in advance

F3HTMLMU is causing u all the grief and trouble.
This is related to the mwsbar BHO.
In other terms its a toolbar that you have in IE explorer that is crashing it.

You can uncheck it from the toolbars or unregister the BHO, or remove it from the registry

Thanks Papa,

There are many toolbars (BHOs) loaded in IE, how to know which BHO is causing problem, can we extract that infromation from the assembly code, for temporary fix i have removed all the toolbar, Is there any way i can learn how to extract the information for assembly code?.

Thanks for you help again

F3HTMLMU is the BHO causing the trouble.

You can search on your hard disk for F3HTMLMU.dll and remove/rename it (i guess programfilesdir+\mywebsearch\bar\1.bin\

Or
Looking in the registry under LocalMachine\software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\ You'll see all the BHO u have.

The F3HTMLMU is the faulty one, so you can search now between these class IDs listed at the registry

eg: {A6A49249-57AE-4295-8D4D-18A9502C7D8E}
wich one reference F3HTMLMU.DLL and remove it.

Todo so search in the whole registry for the key for instance {A6A49249-57AE-4295-8D4D-18A9502C7D8E} you'll see a key, and a key under it named InprocServer32, in its default value you'll find the dll name.
Hope this helps

Hello!Can somebody tell me if i could make the graphical interface for a VC++ program using Macromedia Flash?

Re: GUI

Flash can talk COM, so if your VC program has a COM interface, the flash program can command it to do things, and query it for data to display.

It's an evolving way of writing GUIS...

look at http://topicks.com/ for a demo of a program that does just that

Re: GUI

I don't know the Flash COM interface.There is a change i could find out,or find an article decribeing the interface.

thanks first,
DirectShow and DirectDraw, which one will be better
for rendering video?

DirectDraw's direct Video Memory access (only memcpy(..) )
vs.
DirectShow's Interface ( a few api call)
which one win?

By the way, i found that when i use DirectDraw to draw some video frames, existance of Windows MediaPlayer(it may be a instance of DirectShow i think Confused | :confused:

) is taking affect on my program's performance..which was better. OMG | :OMG:

i guess DirectDraw has some connection with DirectShow,,, Confused | :confused:

what would you like to think about?

thanks again for your time Smile | :)

How to search a substring of a LPWSTR?

Hi~

Is there any function which is used for searching a substring?

for example:
LPWSTR a_string = _T("abcdef");

I would like to cut "cde" out and make a new LPWSTR point to it.

How?

Thanks

If you absolutely positively must use a C-style string, then _tcsstr() is the way to go. Returns a LPTSTR to the position of the first found substring in the original string or NULL if not found.

If you don't really need to use C-style strings, get on the train and use a std::string or std::wstring and its substr() function.

Note! If you explicitly use LPWSTR (as in your question) instead of LPTSTR, then you shouldn't use _T(), but rather L. Otherwise you'll confuse yourself and others by being inconsistent. In other words:

LPWSTR strForcedUnicode = L"abcdef";
LPTSTR strMultibyteOrUnicode = _T("abcdef");

here some functions i wrote recently
i have been planning to rewrite them (wrote them in a hurry)
if you want to replace "cde" then just just do

StrReplace( a_string, "cde", "What to replace it with" );

char * SubStr( char * String, long Start = 0, long Length = 0 )
{
if( Length < 1 || Length > (signed) strlen( String ) )
{
Length = strlen( String );
}

char * Result = new char[Length+1];
long lPos = 0;

for( long i = Start; i < Start+Length; i++ )
{
Result[lPos++] = String[i];
}

Result[lPos] = '\0';

return Result;
}

long StrFindFirst( char * String, char * StringFind )
{
for( long i = 0; i < (signed) strlen( String ); i++ )
{
if( !strcmp( SubStr( String, i, strlen( StringFind ) ), SubStr( StringFind, 0, strlen( StringFind ) ) ) )
{
return i;
}
}
return -1;
}

void StrFindAll( long * Array, char * String, char * StringFind )
{
long count = 0;

for( long i = 0; i < (signed) strlen( String ); i++ )
{
if( !strcmp( SubStr( String, i, strlen( StringFind ) ), SubStr( StringFind, 0, strlen( StringFind ) ) ) )
{
Array[count++] = i;
}
}
Array[count] = '\0';
}

long StrFindCount( char * String, char * StringFind )
{
long count = 0;

for( long i = 0; i < (signed) strlen( String ); i++ )
{
if( !strcmp( SubStr( String, i, strlen( StringFind ) ), SubStr( StringFind, 0, strlen( StringFind ) ) ) )
{
count++;
}
}
return count;
}

char * StrReplace( char * String, char * Find, char * Replace )
{
char * NewString = new char[];
long fCount = StrFindCount( String, Find );
long Found[sizeof(String)];
long fPos = 0;

if( fCount > 1024 || fCount < 1 ) return NULL;
StrFindAll( Found, String, Find );

windows, mouse coordinates with ctrlbars

Hello,

I dont normally ask stuff like this, but I haven't been able to find an answer anywhere Frown | :(

I'm writing an app in windows(MFC) (I have what I think is at _least_ a basic understanding of writing these things, but windows programming is not my forte)

I'm looking to find mouse coordinates in the client area, an easy task you might think...

But alas, no.

The app has 5 ctrl bars dotted about, 2 of which start docked to the sides, and 1 toolbar/ctrlbar, which starts docked to the top. I can access the ctrl bars and do stuff when buttons are clicked and sliders are slid.

hmmm. lets say its a paint app (NDA's etc :/)
what i want to do is pick a tool from the ctrl bar, which i can do, and draw onto the main white bit of the window(the client area, if im correct).
But, because I've got docked things, ScreentoClient doesnt work the way I'd like it to:

GetCursorPos(&c);
ScreenToClient(AfxGetMainWnd()->m_hWnd, &c);

This doesn't return the cursor relative to the TopLeft of the white bit, but to the point below the menubar, where I assume the windows actual client area starts.

So I supose what I'm asking is how do I get the TL corner of the white area? or even if it has different name, what is it called, so I can at least look for the right thing, clientArea isnt tuning up much for me.

I hope that all made sense to someone at least.

Thanks in advance to anyone who takes the time to look at this.

Sorted it now, turns out that the white bit was a seperate child window or similar, not too sure. I:m building off of some other code.

But it works now, and thats what matters Smile | :)

Maybe it's this?

I'm sorry if you're getting annoyed,but I'm only trying to help!
I usually find files by searching google on filename + download

Hope this link is what you're looking for.
