Seems like a paint issue.
Try overriding the OnEraseBkgnd() function.Write the code to put color on the screen there.

Hope this works out for you.(never tried this though...)

cheers!

PS:do comment or call the CDialog::OnEraseBkgnd( pDC ) first before putting in your paint code

Hi
Handle the WM_CTLCOLORDLG and place your painting code inside the handler.

<br />
<br />
HBRUSH CBkColorDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
<br />
	<br />
<br />
	// TODO:  Change any attributes of the DC here<br />
	<br />
	if(nCtlColor == CTLCOLOR_DLG)<br />
	{<br />
		hbr = CreateSolidBrush(RGB(2,22,222));<br />
	}<br />
	else if(nCtlColor == CTLCOLOR_STATIC)<br />
	{<br />
		pDC->SetBkMode(TRANSPARENT);<br />
		hbr = CreateSolidBrush(RGB(2,22,222));<br />
	}<br />
<br />
	// TODO:  Return a different brush if the default is not desired<br />
	return hbr;<br />
}<br />
<br />

that's it

Serious resource leak there Smile | :)

Those brushes should be created and destroyed
outside of the WM_CTLCOLOR handler!

CRecordView, finding and scrolling

Anders Gustafsson12-May-08 7:57

Hi!

I am working with a class, derived from CRecordView. It is a basic customer-maintenance type module where you can either select the record by typing in the key number or scroll back and forth, uisng the standard RecordView buttons. Problem is that quick lookups and scrolling appears to me mutually exclusive.

The person who originally wrote the class solved this by coding the lookup like this:
MoveFirst();
while(!IsEOF())
{
if(m_Nummer==nr)
return TRUE;
MoveNext();
}
This works if the number of records are reasonable (say up to 5000). If I code the lookup with a normal filter and Requery then it is lightinly fast, but Moves fail, presumably because it tries to move within that result set of one record.

Can anyone suggest a solution where I can:
a) Just type in a number and have it pull up the record and
b) be able to use previous/next navigation?

Have you tried checking IsBOF() also?

Yes. If I set m_strFilter and do a requery, I find my record. I then clear m_strFilter. If I then hit previous/next the framework will kick off an extended fetch that will error with 100 (SQL No DATA).

What does work, but is kind of ugly is this:
Open the table, scroll through all records, for each do a:
m_pSet->GetStatus(rStatus);
m_Index[m_pSet->m_Nummer] = rStatus.m_lCurrentRecord + 1;

This builds an index of all records and their absolute numbers. Then in my lookup routine:

m_pSet->m_strFilter = "Nummer=?";
m_pSet->m_Nummerfilter = m_persGrund.m_persnrEdit.m_set.m_Nummer;
m_pSet->Requery();
m_pSet->m_strFilter = "";
m_pSet->Requery();
m_pSet->SetAbsolutePosition(m_Index[m_persGrund.m_persnrEdit.m_set.m_Nummer]);

But this seems like a tremenous kludge for such a simple task?

"Since the record has been found, why?"

You mean "Why hit previous/next" possibly after I have edited and saved? To go to th enext record. Anyway, that is what users do, don't they? Wink | ;)

You don't need to know the position of the icon - let the system do the work for you.

You can use ShellNotifyIcon to show a popup balloon for you. Lookup the docs for the structure NOTIFYICONDATA, and look at NIF_INFO.

I'm pretty sure there's an article or two here on the subject.

Stored the NOTIFYICONDATA struct for later use (not essential, but makes life easy), tweak the NIF_INFO bits, and use Shell_NotifyIcon(NIM_MODIFY, ...) to do this later on...

VC++ 6.0 Output file name for MFC extension DLL

I'm trying to create an MFC extension dll in Visual C++ 6.0. I'm attempting to output the dll with different names to help distinquish the debug files by changing the output file name for the debug configuration...
Project/Settings/Link Tab/Output File Name

I'm getting the following error when I link if I change the output file name from "Test42.dll" to "Test42_DEBUG.dll" in my debug configuration settings.

Linking...
Creating library Debug/Test42_DEBUG.lib and object Debug/Test42_DEBUG.exp
Test42_DEBUG.exp : warning LNK4070: /OUT:Test42.dll directive in .EXP differs from output filename "Debug/Test42_DEBUG.dll"; ignoring directive

Is there another place in the configuration I need to change to get this to work?

That is because the library file name in the DEF file is not changed,
you can find a file named "Test42.Def" in the project, open the file and edit the LIBRARY section to reflect the change

LIBRARY "Test42_DEBUG"

if that is the case you need two different def files for release and debug and set the def file names in the project options Project/Settings/Link Tab/Project Options then edit the /def:".\Test42_DEBUG.def" for debug configuration.

And also, you can actually safely ignore the warning or donot use def files and go for [__declspec(dllimport) and __declspec(dllexport)
declarators.^]

after you get the IHTMLDocument3 interface using [IWebBrowser2::get_Document^] you can get the html text box element using any of the possible methods like [IHTMLDocument3::getElementById^], [IHTMLDocument3::getElementsByName^] to get the IHTMLInputElement interface then use [IHTMLInputElement::get_value or IHTMLInputElement::put_value(^] to set and retrieve the content.

your previous question was to how to get the text from html text box, and if you voted down my previous answer, then it is because that you don't know how to ask question and i don't want to help you any more.

these are the quote from your post,

this seems you already handled the submit event, you want to know how to get the text from the html text box.
