Hi All,
I'm using Visual Studio 2003, and MFC/C++.
I want to simulate just the update/refresh portion of the maximize command, on an ie window. I've already managed to connect to the window and can send minimize and maximize commands to it, as well as move the window around the screen, even hide and show the window if I wish to. I just need to know what message or function I have to pass to that window to get it to do JUST the refresh portion of its maximize command.
Here's some background info and stuff I've already tried:
I have an internet page, that uses java applets served from a server I have no control over. The internet page loads, but none of the background graphics, or button graphics load, so you pretty much have to click on a blank screen and "guess" where the buttons are.
However, if you minimize the window, and maximize (tested over 100 times, by multiple people, under different conditions, with a 100% success ratio), it'll redraw the window properly.
I've tried simulating a very rapid alt+tab and it restored the buttons graphics but not the main graphic (not acceptable to my client). I've also tried the following commands:
::RedrawWindow(hWnd,0,0,RDW_INVALIDATE);
::RedrawWindow(hWnd,0,0,0);
::UpdateWindow(hWnd);
::SetFocus(hWnd);
Any help here would be greatly appreciated.
Thanks,
Brian

Hi
I used RichEdit ctrl with "RICHEDIT20W" for unicode support.
When FindText or FindTextW is called, its getting Failed.
Please could you tell the procedure for utilizing the FindText method
Regards,
nag.

So what does GetLastError() return?

Which either indicates that FindTextW() is not failing, or some other function is being called after FindTextW() but before GetLastError().

FindTextW() returns -1...
AFter calling FindTextW(), immediately GetLastError() is called.
Initially I placed richedit ctrl in dialog...after that RICHEDIT is replaced with RICHEDIT20W in .rc file...
I have to diplay the text with different colors. When RICHEDIT20W is replaced with RICHEDIT, FindText() is not getting failed...

So you have something like:
long lResult = m_richedit.FindTextW(...);
if (lResult == -1)
DWORD dwError = GetLastError();
What happens if you use FindText() with RICHEDIT?

Here is code: <br />
m_listCtrl.SetListView(LVS_LIST);<br />
LV_COLUMN lsCol;<br />
LV_ITEM lsIte;<br />
lsCol.mask = LVCF_FMT|LVCF_WIDTH|LVC_TEXT|LVC_SUBITEM;<br />
lsCol.fmt = LVCFMT_LEFT;<br />
lsCol.cx = 20;<br />
<br />
char* arColumns[7] = {"Date","I","II","III","IV","V","VI"};<br />
<br />
for(int i=0; i<7; i++)<br />
{<br />
lcCol.iSubItem = i;<br />
lsCol.pszText = arColumns[i];<br />
m_listCtrl.InsertColumn(i, &lsCol);<br />
}
error C2065: 'LVCTEXT' : undeclared identifier
'LVC_SUBITEM' : undeclared identifier
lcCol' : undeclared identifier
left of '.iSubItem' must have class/struct/union type
Generating Code...
Error executing cl.exe.
WHAT IS WRONG?
Given this bug. I need to the a header file or what?
What is this?

Should be:
lsCol.mask = LVCF_FMT | LVCF_WIDTH | LVCF_TEXT | LVCF_SUBITEM;

Handle WM_QUERYENDSESSION.

In that case, you could use the SetConsoleCtrlHandler() API.

I've written a control that hosts the web browser which works great when viewing a web page (HTML) but has a problem when viewing an XPS document. When the operator tabs to my host window I send a WM_SETFOCUS message which is processed by the following function:
VOID OnSetFocus(HWND hwnd)
{
IOleObject *pOleObject=getOleObject();
if (pOleObject)
{
RECT rc;
GetClientRect(hwnd,&rc);
pOleObject->DoVerb(OLEIVERB_UIACTIVATE,NULL,pSites,0,hwnd,&rc);
IWebBrowser2 *pWebBrowser=NULL;
if (pOleObject->QueryInterface(IID_IWebBrowser2,(void **)&pWebBrowser)==S_OK)
{
IOleInPlaceActiveObject *pOleInPlaceActiveObj=NULL;
if (pWebBrowser->QueryInterface(IID_IOleInPlaceActiveObject,(void **)&pOleInPlaceActiveObj)==S_OK)
{
MSG msg={0};
msg.hwnd=hwnd;
msg.lParam=1;
msg.wParam=VK_TAB;
msg.message=WM_KEYDOWN;
pOleInPlaceActiveObj->TranslateAccelerator(&msg);
pOleInPlaceActiveObj->Release();
}
pWebBrowser->Release();
}
}
}
The above works fine for web pages as focus always seems to be changed to the first window below 'Shell DocObject View' which for web pages is 'Internet Explorer_Server'. When using the XPS view plug-in there are two levels below which are 'DocObject_Top_Class' and 'HwndWrapper'.
The window layouts when viewing a web page looks like this:
MyHostWindow
ShellEmbedding
Shell DocObject View
Internet Explorer_Server --> This window gets the focus which means the tab key continues to function
The window layout when viewing an XPS document looks like this:
MyHostWindow
ShellEmbedding
Shell DocObject View
DocObject_Top_Class --> This window gets the focus which means the tab key stops working
HwndWrapper[WCP_Hosted... --> Focus should be here so the tab key continues to function
Does anyone know how to sort out the focus problem?

There is no source code available for the current location!
When my VS2005 run the vc++ project, it will appear above message.
But my VS2005 did not have this problem yeaterday.
How do I solve this problem?

Hi,
Generally people use 'new' keyword to memory allocation. But I red that it will slow down the process or project. I also know that using virtual memory is one of solution to it. But the thing is, I am not getting how to implement this code in C++/MFC. Please help me to achieve this feat by providing any one of simple program.
Thanking you,
-Jagadeesh Musham

I will make a citation that I read somewhere (sorry, I don't remember from who it was):
"Early optimization is the root of all evil". Specially in your case if you don't know exactly what you are doing and you just heard that somewhere.
So, are you having troubles ? Is your program becoming slow ? Are you allocating/dealocating a lot (and when I say a lot, read it as really a LOT) of objects ?
If no, then you will probably make things a lot more complex and probably much buggy than they are. Because if you need to implement a system that manages memory allocation in a more efficient manner it's going to be quite complex.
Finally, I really would like to see where you read it and if you didn't interpret the thing out of context (or maybe the author is just plain stupid). C'mon you're not going to experience slowdown if you allocate a bunch of integers or objects.

Knuth: We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil." (Knuth, Donald. Structured Programming with go to Statements, ACM Journal Computing Surveys, Vol 6, No. 4, Dec. 1974. p.268.)
BTW, my favorite one on the topic is:
