It is possible, yes, but you have to code it, afaik by defaults there's no pre-maid way to do it.
You have to use FindResource, LoadResource, LockResource, CRichEditCtrl::StreamIn in to read the file up from memory.

As a follow up to this I have successfully managed to load the file as a resource, which is brilliant so thanks for the help.
One problem I am experiencing though is that I want to extract different sections of the file dependant on conditions, and I'm finding that if the document is saved from Micorsoft Word 2003 the string doesnt seem to be able search the file content, but using Wordpad all is OK.
I have just typecast the LPVOID I receive from LockResource to a CString
<pre>
CString csMess = (LPCTSTR)lpResLock;
</pre>
As I say this is OK if the file is saved from WordPad.
Any Suggestions?

i create a edit control whose parent window is in another process, i hook the parent window callback functin, just like this:
SetWindowsHookEx(WM_CALLWNDPROC, MyCallbackFunc, hDllMOdule, idProcss)
but i can't receive WM_CTLCOLOREDIT in my callback function, why?
i'll cry, who can help me? thank you very much

Is your edit control read-only or disabled?
From MSDN:
Read-only or disabled edit controls do not send the WM_CTLCOLOREDIT message; instead, they send the WM_CTLCOLORSTATIC message.

no, it can gain input
My code like this:
LRESULT CALLBACK HookProc(int nCode, WPARAM wParam, LPARAM lParam)
{
PCWPSTRUCT pWps = (PCWPSTRUCT)lParam;
if (pWps->hWnd == hookWnd)
{
switch (pWps->message)
{
case WM_CTLCOLOREDIT:
{
some operation! // never receive this message
}
break;
}
}
}

Do I understand you right? Somehow you got the hWnd of an external app, after that you created an
edit control from your app and attached it to the parent hWnd from the external app?
If so, then this might be the problem (from MSDN):
The WM_CTLCOLOREDIT message is never sent between threads, it is only sent within the same thread.
This is just an assumption and maybe someone else could approve or disprove this.

yes, you are correct! i'll cry, how can i do, it can't communicate between process, but i need this character

Here is some code I used with a low-level key hook to attach my thread input to the ones of the other
process. I used it in combination with ToUnicodeEx to get the displayed char. But I don't think this will solve your problem but I would give it a try.
Attach:
DWORD dwThreadWindow = GetWindowThreadProcessId(pVirtualLLKeyBoard->GetMessageWnd(), NULL);
DWORD dwThreadForeWin = GetWindowThreadProcessId(GetForegroundWindow(), NULL);
BOOL bAttach = FALSE;
BOOL bAttached = FALSE;
if(dwThreadWindow != dwThreadForeWin)
{
if(dwThreadForeWin != 0)
bAttach = TRUE;
}
if(bAttach)
bAttached = AttachThreadInput(dwThreadForeWin, dwThreadWindow, TRUE);
"pVirtualLLKeyBoard->GetMessageWnd()" is the window of my app.
Detach:
if((bAttach)&&(bAttached))
AttachThreadInput(dwThreadForeWin, dwThreadWindow, FALSE);
After you got the hWnd from the other process, I would try to attach your thread to the window owning thread of the external application. On exit just detach it.

Hi,
MFC CListctrl flickers when i delete all the items and reload the list control at a frequency of 1 second. I am using .DeleteAllItems() method to delete all the items and .InsertItem() method to insert the items one by one. I am using a timer at a frequency of 1 second to delete and reload my CListCtrl.
So everytime it come across the DeleteAllItems() method, it shows a large flickering on the dialog window contains the CListCtrl.
Please suggest me any method to reload all the items without any flickering.

|
|
|
|
m_List.SetRedraw(FALSE);
m_List.SetRedraw(TRUE);
m_List.Invalidate();
m_List.UpdateWindow();
|
|
|

Thank you very much LunaticFringe for the above method.  That worked for me.
Regards and Thanks

if i select the segment of one edit content, its background color is blue, how can i make it transparent?
you can figure it if you drag mouse over my question, it arise blue background, how can i avoid it?
|
|
|
|
|
By using something like a custom edit control, possibly? That's one which you pretty much write yourself...
The blue selection thing is kind of built into the standard controls - and into the standard Windows UX. How are you going to indicate a selection?
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

If you are using MFC, then you can try subclassing the editbox and call SetSel(-1, 0) in its OnMouseMove() handler.

i use windows api, not mfc.
