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.

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.

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!

I am facing problem in finding how can we list all the deleted files in a directory??? I mean is there no way of doing it by some function rather than making a function urself????Can FindFirstFile,FindNextFile can be useful???

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.)

Hi All.
I need to know how can i write some function that getting Folder path and return me list of all file in this folder.
The function will be something like this

{
...
...
...
While(bFileExist){
sFileList += File.Name;
sFileList += '\n';
bFileExist = FindNextFile(....);
}
}
Thanks for any help.

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,

That is something that looks like a thermometer.
If you couldn't find what you want, it shouldn't be too hard to modify it so that it reports temperature.
- It's easier to make than to correct a mistake.

Those are sliders.... They give input to the application... they don't report anything... And, to be honest, they don't look like thermometers at all

Me doing your homework? No.
Helping you with specific problems and unexpected behaviour of your code? Yes.
Post what you have, tell us what doesn't work and you will get tons of replies. To THIS question, this probably will be the only reply.
Cheers,
Sebastian

I'm getting errors about something called RTC. What does it do, and what library can I find the functions for it in?

I used GetPrivateProfileSectionNames to retrieve a list of the section names. The only problem is that I now have all the names stored into one char array seperated by \0s. What would be the best/easiest way to split the string up into individual char arrays. Also note that there won't be a set number of section names. Thanks for any help.

The easiest way is to use one of the container classes and one of the string classes, I recommend std::vector and std::string. Then simply copy the strings from the input buffer.
std::vector<std::string> names
char * ptr = buffer;
while (*ptr)
{
names.push_back(ptr);
ptr += strlen(ptr) + 1;
}
You may be right
I may be crazy

Here is a way to parse the buffer and load each string into a CStringArray. If you need to.
<code> LPTSTR lpszBuffer = new TCHAR[512+1];
DWORD dwRet = GetPrivateProfileSectionNames( lpszBuffer, 512, lpszFile );
if( dwRet == 0 )
return;
CStringArray secnames;
secnames.RemoveAll();
LPCTSTR p = lpszBuffer;
DWORD dwLen = _tcslen(p);
while( dwLen > 0 )
{
p = &p[dwLen + 1];
secnames.Add(p);
dwLen = _tcslen(p);
}
delete [] lpszBuffer;
for(int i = 0; i < secnames.GetSize(); i++)
{
if( !secnames.GetAt(i).IsEmpty() )
m_cIniEdit.ReplaceSel("["+secnames.GetAt(i)+"]"+"\r\n");
}
