Can't prevent new window opening!

Hi there,
can anyone tell me how to stop a link opening in a new window and just use the existing window??
For example: I've got a little explorer app(MFC) with 2 windows. The left side displays the C:/drive
and the right side displays a FTP address. The left window navigates fine, but the right side insists on opening
a new explorer window when I click on a link, instead of changing inside its own window. When the ne window opens... that navigates fine... just the way I want the right side widow to.

Its probably something stupid, knowing me... definately something stupid Smile | :)

But I've tried a bunch of stuff for the last
24 hours now and nothing stops it opening in a new window!
Help!

If I understand you correctly, the right pane is actually an HtmlView displaying a web page. In any case, to redirect a link to a specific window you have to use the "target" property. For example:

// somewhere in an HTML file
<a href="http://www.website.com" target="_self">Click here</a>

"target" accepts any of the following:
_blank, which opens the link in a new window
_self, which opens the link in the current window
_parent, which opens the link in the parent window
_top, which opens the link in the top most window

Hope this helps.

Thanks for the reply man, but(as usual) its not the HTML I need to change.
Basically its an Explorer Window displaying content on a server via FTP:

Naviagte2(_T(ftp://whatever.com),NULL,NULL)

It displays fine but when I want to open a folder - it launches a new explorer window outside the application and displays the info in that window.

Is there some way of controlling this so that all clicked links open inside the application only?
thanks Smile | :)

handle OnBeforeNavigate2, cancel the navigation if it's to another window, and navigate to the url just cancelled... something like that.

You need to subclass your static control. Then overwrite the OnPaint() member with the following example:

void CMyStaticCtrl::OnPaint() <br />
{<br />
	CPaintDC dc(this); // device context for painting<br />
	<br />
CFont newFont;<br />
LOGFONT lf;<br />
<br />
//Create large Font<br />
memset(&lf, 0, sizeof(LOGFONT));<br />
lf.lfHeight = 20;<br />
lf.lfWeight=FW_BOLD;<br />
strcpy(lf.lfFaceName, "ARIAL");<br />
newFont.CreateFontIndirect(&lf);<br />
<br />
dc.SetBkMode(TRANSPARENT);<br />
dc.SetTextColor(RGB(255, 0, 0));	<br />
dc.SelectObject(&newFont);	<br />
dc.TextOut(0, 0, "Text in Arial, bold, red");<br />
}

Hope this helps

A little irritating that you need to subclass to just change the color.

That's right, but the "normal" way didn't work for me. It changed the font, but not the color and the background appeared white even though i set it to transparent.

lpClassName is either an existing class name

Button, Edit, SysTreeView32, ...

or a class that you registered via RegisterClassEx().

You will have to write a BHO(Browser Helper Object).
You can start from here[^]msdn

Also look for BHO samples here in codeproject also.

Make a call to my ActiveX from my .aspx webpage.

anderslundsgard27-Sep-04 20:54

27-Sep-04 20:54

Hi!

I’m creating an ActiveX control in my myapp.aspx-page using the <object> - tag.

<br />
<OBJECT id="objComp" style="Z-INDEX: 101; LEFT: 24px; WIDTH: 974px; POSITION: absolute; TOP: 40px; HEIGHT: 538px"<br />
</OBJECT><br />

At this time I’m only using the ActiveX technology to publish my MFC application on the net. I’m about to make a call to may webpage like this:

http://www.mypage.com/myapp.aspx?user=bill&password=12345

How may I pass the “user” and the “password” into my ActiveX?

Can I how do I access the properties of my ActiveX from my page?

The ActiveX is supposed to run on the client – not on the server.

hi ya its for sure that ActiveX runs on client side
you can access methods as well as properties exposed by your control from your page
e.g. if your control exposes a method like SetUseridPassword(BSTR usrID,BSR password) then you can access it as follows

<OBJECT
     ID="MyActiveXID"
     CLASSID="clsid:your-control-class-id-here"
     CODEBASE="TestAX.ocx"
     TYPE="application/x-oleobject"
>

then on any event (like button's onClick) call the following following function like onClick='InitValues'

don't forget to define this script in head section of your page.

<script language="JavaScript">

function InitValues()
{
MyActiveXID.SetUseridPassword("testusr","tstpassword")
}

</script>

Hi All,
I used SuspendThread and ExitInstance to stop a thread created using AfxBeginThread Function. But in some newsgroup messages it is stated that this is not the right method. I've used PostThreadMessage using WM_QUIT, but this is not working. So How to stop a thread created using AfxBeginThread function.
Thanx in Advance

To use PostThreadMessage it should be a UI Thread with message loop. Wot kind of thread you created worker thread or UI thread ?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
