There are several here on CP, search for "layout manager" or "resize manager"

Change the selection style of a listbox on the fly

shultas31-Dec-03 4:44

Hello everyone.

I have built a program with a listbox on the main dialog. I desire to use this listbox for multiple purposes, sometimes allowing the user to select an item out of it, othertimes not allowing them to select anything. What I am wondering, is it possible to have code within the program that changes the "selection" property of the listbox from "Single" to "None"?

Thanks!

One solution is to derive a class from CListCtrl and do custom selection. Otherwise, one possible solution is to intercept the mouse click.

Sure, the selection type is determined by the listbox styles LBS_NOSEL and LBS_MULTIPLESEL so you'd just toggle on/off the style bits as appropriate.

(I'm new at VC++). I've been looking for an hour on how to do this. I am wondering could you give me an example of how I would do this? (I tried looking for things such as m_ListBox.SetStyle() but could not find anything?)

Thanks for the reply I do appreciate it!

See CWnd::GetStyle() and ::SetWindowLong() to dynamically change a control's style.

Close, CWnd::ModifyStyle() is the function to use (assuming you're using MFC which it looks like you are)

// Change to no selection
m_ListBox.ModifyStyle ( LBS_MULTIPLESEL | LBS_NOSEL, LBS_NOSEL );
// Change to multiple selection
m_ListBox.ModifyStyle ( LBS_MULTIPLESEL | LBS_NOSEL, LBS_MULTIPLESEL );
// Change to single selection
m_ListBox.ModifyStyle ( LBS_MULTIPLESEL | LBS_NOSEL, 0 );

Change Background color of a word in CRichEditCtrl control

Hi,

Can anyone please give me a clue about changing the background color of a word in a CRichEditCtrl control?

I've seen the documentation on Rich Edit 2.0 (whereever that lives!) and CHARFORMAT2 but whenever I try it the background color remains unchanged.

Hi there and many thanks for your reply.

I had already read this article but I dont think it helps with changing the background colour of an individual word.

However, I just found a great article by Andrew Forget (CodeGuru) about Rich Edit 2 and I am hoping that this does the trick.

Have a happy and prosperous new year!

Windows Clipboard

I wish to copy a string of text to the Windows clipboard and paste it from it to an edit control.

what is the process? i tried consulting with MSDN, however, i couldn't understand the process, and where exactly is the reference to the Edit's handle.

Can someone explain shortly how it works, and what are the steps to be performed?

One solution is via COleDataSource.

char sString[5] = "2004";
sString[4] = '\0';
HANDLE cbData = ::GlobalAlloc(GMEM_MOVEABLE, 5);
PTSTR pData = static_cast<ptstr>(::GlobalLock(cbData));
_tcscpy(pData, sString);
::GlobalUnlock(cbData);
COleDataSource *pODS = new COleDataSource;
pODS->CacheGlobalData(CF_TEXT, cbData);
pODS->SetClipboard();

Check out MSND.

virtual printer driver

SHOJO31-Dec-03 2:05

SHOJO

31-Dec-03 2:05

I want to write a virtual printer driver.
The driver should be used from any print-dialog like any other printer which is installed on the system.
It should get the pages to print, change them and give them to the "real" printer.
Probably someone knows how to write such a driver an how to give the data further to the "real" printer.

Is this possible with Visual C++ and MFC? And how to make it?

I hope someone can answer me because there are very few things on this topic on the internet.

How to bypass login window?

I want to develop a application which will connect me directly to yahoo messenger window(or any desktop application). i.e entering username and password in Login window will be handled by my application.
Any suggestions?

It is only a wild guess

I would Install a System wide CBT Hook and wait for the creation of Yahoo Login window (will work definitly)

then as soon as the window is created Use SetWindowText to set the Text in the username window and Password (might work)

and then send the dialog a message for Button click (will work)

Hope it helps Smile | :)
