You can use FormatMessage to see the description of the error, as in the following code excerpt (from MSDN)

LPVOID lpMsgBuf;
FormatMessage( 
    FORMAT_MESSAGE_ALLOCATE_BUFFER | 
    FORMAT_MESSAGE_FROM_SYSTEM | 
    FORMAT_MESSAGE_IGNORE_INSERTS,
    NULL,
    GetLastError(),
    MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
    (LPTSTR) &lpMsgBuf,
    0,
    NULL 
);
// Process any inserts in lpMsgBuf.
// ...
// Display the string.
MessageBox( NULL, (LPCTSTR)lpMsgBuf, "Error", MB_OK | MB_ICONINFORMATION );
// Free the buffer.
LocalFree( lpMsgBuf );

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Combo box in CListCtrl

I am working on creating a drop down combo box if user clicks on a column in a list control. I have got one document in the link: http://www.codeproject.com/listctrl/CustomizedReportListCtrl.asp

But the problem is CBS_DROPDOWNLIST style has been used in that combo list. But I want to make that combo box editable. CBS_DROPDOWN is not working. Could anyone tell me how to do that?

You need to be very clear instead of saying "not working", while asking there ,too.

I removed default hover behavior in my toolbar. Can I get it back?

Hi, I have a CToolbar and somehow managed to cause the buttons in the toolbar to not have a box drawn around them when the user's mouse is positioned over them. Is there an easy way to get this behavior back?

I don't know how I managed to remove this behavior, that's why I have no idea how to put it back in.

Thanks,

Max

I think I know more about what the problem is now: My buttons are *disabled*. Is there a way in the toolbar editor to set a button to be enabled?

I see what is going on! If I do not assign the button an ID like "ID_APP_ABOUT", the button is disabled. It looks like the ID must match one of the symbols in the resource symbols list. I have two more questions about this:

How do I make a new symbol, should I be using a wizard?
How do I add an entry to the message map? (use a wizard?)

By this, I mean the list below

BEGIN_MESSAGE_MAP(MyApp, CWinApp)
ON_COMMAND(ID_APP_ABOUT, &MyApp::OnAppAbout)
// Standard file based document commands
ON_COMMAND(ID_FILE_NEW, &CWinApp::OnFileNew)
ON_COMMAND(ID_FILE_OPEN, &CWinApp::OnFileOpen)
// Standard print setup command
ON_COMMAND(ID_FILE_PRINT_SETUP, &CWinApp::OnFilePrintSetup)
END_MESSAGE_MAP()

Thanks, I will learn from a book I have

Redraw Controls

25-Mar-07 23:11

Hi everybody,

i still have a problem with the redraw of controls.

The Return-Key on a Grid provokes a switch of the view in the current Tab(of the TabControl)
The new view will be created, drawn, all ok.

I switch to another application (firefox for example) then i return to my application and the Grid is invisible. Sizing the frame provokes a OnSize and the all controls will be redrawn, the grid is already visible(drawn)

Now, i removed the Line "Grid->RedrawWindow(...);" from out the OnEraseBgnd-Handler.
The problem is solved, but now i have the initial problem :

At creation, the grid will be created and correctly drawn, then if a Thread has extracted all informations, the grid will be filled with the data.

Just at this time, the grid disappears.
It could be a problem of the grid, but i don't think so, because i have the same effect with textboxes.

The textbox which gets the focus during initialisation, will not be drawn Sigh | :sigh:

Does anyone has an idea?

Big thanks Smile | :)

I writed an activex in MFC, one of the methods is as follow:

<br />
.odl:<br />
[id(57)] boolean GetOneValueRange(long Address, float* pMinValue, float* pMaxValue);<br />
<br />
.h:<br />
afx_msg BOOL GetOneValueRange(long Address, float FAR* pMinValue, float FAR* pMaxValue);<br />
<br />
.cpp:<br />
BOOL CXXXXCtrl::GetOneValueRange(long Address, float FAR* pMinValue, float FAR* pMaxValue)<br />
{<br />
	...<br />
}<br />

I hope this activex can be used in VB and javascript, is there any changes must made?
