Do you want to convert a multiline string into a single line one. Although you talk about removing extra spaces but from the example it seems you want to remove newline ('\n') character.

Hi,

I have created a small project in vc++6 with a editable list control. I took the help of some of the articles found here.

I wanted the listview's edit box to have some background colour when that box is being edited. I intergrated another class I found in CodeProject. But the box doese'nt behave properly. I do not know how to correct it, or what I should change.

Can somebody help me out. I can e-mail the project to you so that you can see it and tell me what I must add or change.

Thanks.
Tara

use WM_CTLCOLOREDIT message in your class(derived CListCtrl) and use

<br />
HDC hdc=(HDC)wParam)<br />
::SetBkColor(hdc,RGB(53,197,200));<br />

I have added that to the class. But this is what is happening:
When I click on a cell in the listview the background changes color. After that, when I start typing the color changes back to white and the corners remain yellow...

Please help!

Thanks.

MFC LoadFrame Bug [modified]

11-Jun-06 2:35

Hope I understood your question
WM_CTLCOLOREDIT is a message notify

you can see in MSDN(this explain)
"This message notifies the parent window of an edit control when the control is about to be drawn. By responding to this message, the parent window can use the specified device context handle to set the text and background colors of the edit control."

see this code maybe it is some helpful to you :

<br />
BEGIN_MESSAGE_MAP(CAnswerView,CListView)<br />
	ON_MESSAGE(WM_CTLCOLOREDIT, OnColorEdit)<br />
END_MESSAGE_MAP()<br />
...<br />
...<br />
LRESULT CAnswerView::OnColorEdit(WPARAM wParam,LPARAM lParam)<br />
{<br />
	HDC hdc=(HDC)wParam;<br />
	SetBkColor(hdc,RGB(53,97,200));<br />
	SetTextColor(hdc,RGB(255,255,255));<br />
	return (LRESULT)m_Brush->m_hObject;<br />
}<br />

pFrame->LoadFrame(IDR_MAINFRAME, WS_OVERLAPPEDWINDOW | FWS_ADDTOTITLE, NULL, NULL);

as we know, this is a simple way to create and load the frame with its resouces,

and we notice that the pContext is NULL. And we get a bug:

if pContext is NULL, it will fire CView::OnInitalUpdate Twice!

Here is My explain:

BOOL CFrameWnd::LoadFrame(...)
{
...

if ( !Create(...) ) /// it will fire CView::OnInitialUpdate()
{
return FALSE;
}

...

if ( pContext == NULL )
{
/// it will fire CView::OnInitialUpdate() again
SendMessageToDescendants(WM_INITIALUPDATE, 0, 0, TRUE, TRUE);
}

return TRUE;
}

So, why these four lines:

if ( pContext == NULL )
{
SendMessageToDescendants(WM_INITIALUPDATE, 0, 0, TRUE, TRUE);
}

Can anyone help me or fix it?
Thanks!

You can enumerate the contents of the Recycle Bin and look at the original location of the files. The only other alternative would be to parse the file system structures (similar to what ScanDisk and NDD do) and look for directory entries marked as deleted. (But even then, the file's data may have been overwritten.)

use the shell api SHBrowseForFolder once you select a folder use FindFirstFile and then FindNextFile to retrieve all the files under that folder.

hope this helps

Hey folks!

I'm installing an Internet application which requires a cookie to authenticate. Because it's a low-risk application, I'm using persistent sesssions.

I'd like users to have to enter a login/password to access the service.

There are a bunch of issues with this (checking for valid input, not letting users advance in the installation if they can't enter their login/pass correctly, grabbing the cookie back from the response) and I'd like to know if there are any *free* (not GPL or LPGL) classes or projects, which would allow me to plugin this feature into my application. i.e. i'm looking for login functionality like you might see such as with MSN Messenger.

C++ / MFC is available, but no .NET.

waiting hopefully :P,

I've seen controls that look like Oscopes, Histograms and Volt Meters.... but I am looking for one that looks like a thermometer to report back temperarture... for use in C++/MFC application

Does anyone have any like that or can point me to something.

You might want to check this out: http://www.codeproject.com/useritems/MAC_Slider.asp[^]. It does look like a thermometer, but it's a C# control.

That is something that looks like a thermometer. Big Grin | :-D

If you couldn't find what you want, it shouldn't be too hard to modify it so that it reports temperature.
