In my application, have a EditBox and a WebBrowser2 control,I want to drop a select range's html source to the EditBox control,when I use WebBrowser2 control to navigate a Web page.
My original way is,when a event(mouse dorp) coming , I send a copy(Ctrl + C) event, then paste the content in the clipboard,but I think is effect on the other program. So I want other way for resolute this problem.
Very thanks.

Use the DOM to get a pointer to the IHTMLInputElement which represents your editbox. Then set the new value, and call reset() on the embedding Form to apply the new value.

very thanks,Have you got other way? eg: I use IHTMLDocument2 interface,
call IHTMLDocument2::get_selection() get a IHTMLSelectionObject interface,
and call IHTMLSelectionObject::createRange() get IDispatch
then I didn't know how to get innerHTML From IDispatch.
my idea was born from a javascript function(document.selection.createRange().innerHTML)

You will have to do OwnerDraw.

Hi,
I am curious about OLBs and TLbs, when would you use a OLB over a TLb. Could anyone explain the difference, pros+cons etc.
Cheers

What is an OLB or a TLB ?

the .OLB extension name has been used in the past by MS along with Office, referring to their office object model. OLB stands for Object library, a way to refer to an automation-enabled object model.
the .TLB refers to a type-library, which is also an object library. But a .tlb is not necessarily automation-enabled.
Both are type libraries, generated by compiling IDL interfaces. To become automation-enabled, a type-library must expose dispatch interfaces.
A type-library is registered by its GUID in the registry (hkcr\typelib). So actually nobody really cares about the extension name you give it.
Sometimes, a type-library is even embedded in the COM server itself (as a .rc binary blob).
If that was only for the sake of semantics, you would use an .OLB extension name with automation-enabled object libraries (usable with VB, Perl, Python, ...). And you would use .TLB for all other object libraries.
VC7 doesn't change anything about it, except at design-time : you don't need an external IDL file anymore to declare type libraries.

Is there a rule that you can not load images/cursors/bitmaps during the WM_CREATE message from the resource script.
I can load my icon from the resource file in dialog procedures, basically all other messages except WM_CREATE which is where I need it to place them on my button controls. They do load however when I use LoadCursorFromFile (for cursors)... The error code is 1813 (The specified resource type cannot be found in the image file)...Even though it does exists (Tested the same code in the WM_CTLCOLORLISTBOX message, odd place to put it I know but it was just a test, and it worked fine) This is annoying me greatly and if anyone has any feedback on this matter it would be much appreciated.

How does one clear all information in a list box?
Cheers
Ayush
|
|
|
|
|
SendMessage(hwnd, LB_RESETCONTENT, 0, 0);
hwnd = handle to the window (list box)
|

Hi!
The easier way to clear a listbox contents is to use the ResetContent function.
If your control member variable that represents your ListBox is m_lsXXX
then just write m_lsXXX.ResetContent();
I hope this helps

Hi,
In my SDI application I override menus to be ownerdrawn, and then draw them using OnDrawItem(...) of the main frame. However, i have this little problem: I click on the main menu, then a pop-up appears, I select a pop-up menu item, it displays a pop-up of next level. This second level menu partly overlaps the first one, and when it disappears the first menu doesn't get updated (part of the menu item which is selected has an unupdated trace on it). This doesn't happen with not ownerdrawn menu items.
Does anybody know what else should I do to provide all menu items get updated when necessary
Regards,
Vitaly

easy, only need to use 2 messages:
WM_MEASUREITEM and WM_DRAWITEM.
here is some code copied from my program, as a reference for u:
in WM_MEASUREITEM, call
void BMenuDraw::MeasureItem(int nIDCtl, MEASUREITEMSTRUCT *p)
{
NodeImage*pn=(NodeImage*)p->itemData;
ASSERT(pn!=0);
CString cs=pn->GetText();
HDC hdc=::GetDC(0);
CDC*pDC = CDC::FromHandle(hdc);
CSize size=pDC->GetTextExtent(cs);
p->itemWidth =size.cx+24;
p->itemHeight =22;
::ReleaseDC(0,hdc);
}
in WM_DRAWITEM, call:
void BMenuDraw::DrawItem(int nIDCtl, DRAWITEMSTRUCT *p)
{
CDC*pDC = CDC::FromHandle(p->hDC);
NodeImage*pn=(NodeImage*)p->itemData;
COLORREF clrBk =::GetSysColor(COLOR_MENU);
COLORREF clrTxt =::GetSysColor(COLOR_MENUTEXT);
COLORREF clrBkH =::GetSysColor(COLOR_HIGHLIGHT);
COLORREF clrTxtH =::GetSysColor(COLOR_HIGHLIGHTTEXT);
CString cs;
if(p->itemAction==ODA_DRAWENTIRE)
{
P_DrawItem(pDC,pn,p->rcItem,p->itemState,clrBk,clrTxt);
}
if(p->itemState&ODS_SELECTED)
{
if(p->itemAction&(ODA_SELECT|ODA_DRAWENTIRE))
{
P_DrawItem(pDC,pn,p->rcItem,p->itemState,clrBkH,clrTxtH);
}
}
else
{
if(p->itemAction&ODA_SELECT)
{
P_DrawItem(pDC,pn,p->rcItem,p->itemState,clrBk,clrTxt);
}
}
}
void BMenuDraw::P_DrawItem(CDC *pDC, NodeImage *pn, const CRect &rcItem, int iState, const COLORREF clrBk, const COLORREF clrTxt)
{
BOOL bDis=(iState&ODS_DISABLED)?1 ;
BOOL bChk=(iState&ODS_CHECKED)?1 ;
BOOL bSel=(iState&ODS_SELECTED)?1 ;
BImageHold*pHold=image.GetMenuHolder();
const int iBmpWH=pHold->iBmpWH;
int iBkMode=pDC->SetBkMode(TRANSPARENT);
int iX=rcItem.left+3;
int iY=rcItem.top+2;
CRect rcTxt =rcItem;
rcTxt.left =iX+24;
rcTxt.top +=2;
pDC->FillRect(&rcTxt,&CBrush(clrBk));
CDC dc; dc.CreateCompatibleDC(pDC);
CBitmap*pBmpOld;
if(bDis) pBmpOld=dc.SelectObject(&pHold->bmpD);
else
if(bChk) pBmpOld=dc.SelectObject(&image.bmpS);
else pBmpOld=dc.SelectObject(&pHold->bmpN);
pDC->BitBlt(iX,iY,iBmpWH,iBmpWH,&dc,pn->iPos*iBmpWH,0,SRCCOPY);
CString cs=pn->GetText();
COLORREF clrTxtOld;
if(bDis)
{
BYTE iClr=223;
clrTxtOld=pDC->SetTextColor(RGB(iClr,iClr,iClr));
rcTxt.top++;
rcTxt.left++;
if(!bSel) pDC->DrawText(cs,&rcTxt,DT_EXPANDTABS);
rcTxt.top--;
rcTxt.left--;
COLORREF clrTxtDis=::GetSysColor(COLOR_GRAYTEXT);
pDC->SetTextColor(clrTxtDis);
pDC->DrawText(cs,&rcTxt,DT_EXPANDTABS);
}
else
if(bChk)
{
BYTE iClr=223;
clrTxtOld=pDC->SetTextColor(RGB(iClr,iClr,iClr));
rcTxt.top--;
rcTxt.left--;
if(!bSel) pDC->DrawText(cs,&rcTxt,DT_EXPANDTABS);
rcTxt.top++;
rcTxt.left++;
pDC->SetTextColor(clrTxt);
pDC->DrawText(cs,&rcTxt,DT_EXPANDTABS);
}
else
{
clrTxtOld=pDC->SetTextColor(clrTxt);
pDC->DrawText(cs,&rcTxt,DT_EXPANDTABS);
}
dc.SelectObject(pBmpOld);
pDC->SetBkMode(iBkMode);
pDC->SetTextColor(clrTxtOld);
}
in code above, i used menu image (NodeImage), u just modify it a little, must be well.

hi everyone,
I read the article "Printing Made Easy with MFC" and am using the GPrintUnit and GPrintJob classes.
I would like to know how to redefine the Rect for printing, or more specifically how to introduce a margin so that my printing does not start on the edge of the page.
Thanks in advance
Regards
Rui

Thanks for the article, it does explain quite a bit on printing.
But I was wondering more about where to set the JRECT defined in the classes GPrintUnit and GPrintJob?
Although I am going to try to override the GPrintInfo function and set the JRECT there. I am not sure if this is correct.
Thanks
Rui

hi,
I defined a message in *.exe. And in *.dll, I trigered the message, nothing happened. tell me why.
Note, this message works well in *.exe
Thanks in advance

Did you add a command handler for that message?

Are you sending the message to the correct window?

Is there any application written in VC++, regarding voice communication, you aware of; then please let me know.
There is one here at CP, but it gives lot of echoes and code not of good quality. If there any other present somewhere like MSDN or M$ research site, you aware of then please let me know.
BTW: i've already searched google but it is giving results that are either Unix related or difficult to compile in VC++

If you want to add Text-To-Speech then get the SDK from Microsoft, there are many examples in C++ which work well.

No, I don't want anything like text-to-speech. What i want is to transfer voice over lan/internet in peer-to-peer or client/server manner

There is example voice chat software in the DirectX SDK
