"Active window" is too vague a term to provide a specific answer for. Is it a dialog, a control on a dialog, a view, a control on a (form) view, or something else? Please explain further.

if i understood u well:
try following:
HWND hwnd = FindWindow(...); // or sequnce of call of FindWindowEx
// to know a valid window's tree use spyxx from the vs tools.
SetWindowText(hwnd, "SomeText"); // This code change captions.
// or to fill up an edit

Are you talking about the desktop's background (i.e. wallpaper)? If so, check out SystemParametersInfo(SPI_SETDESKWALLPAPER, ...).

Yes.
You need to familarize yourself with all of the standard controls that are available (e.g., MFC, ActiveX) so that you will know what each can and cannot do.

Hi,
Recently I was testing an activeX component into an MFC application developed with Visual Studio .NET 2002 (MFC 7.0). Because I have some problem with it, I test other known Active X (as Microsoft Forms 2.0 Command Button and Microsoft Forms 2.0 Option Button) and i get problems too. I can move controls, some dialogs are blocked...
Have you ever used any ActiveX component in a Visual Studio .NET 2002 MFC Application? Have you ever get any problem with it?
Thanks for your attention.

I just created a test dialog with my VS .NET 2003. In it I placed Microsoft Forms 2.0 Command and Option Buttons. When I used the Test Dialog option to test-run the dialog, both ActiveX controls were displayed properly.
You should try using the ActiveX Control inside the ActiveX Control Test Container. If they run properly, then the problem is in Visual Studio .NET 2002. Perhaps a bug ?

Yes, all controls I have tested are showed properly. But i have problem when trying to move, for example. Add a commandbutton and try to use SetWindowsPos to move the button. Other error i have is that when I use option button activeX, the application launch an exception.

I must be being really stupid here; but I can't see any way to remove the sunken border which appears by default around a dropdown combo box. Is there any way to remove it?

i cant see too.
in my childhood i've use foolowing sollution:
if u want to use flat-control interface anywhere change combobox onto edit-button-listbox group with flat property true. the only problem is to syncronize'em 
|
|
|
|

Derive your own CComboBox class and implement OnNcPaint handler. If you do nothing in that handler, no border will be appear. That is your starting point to draw your own border.

Yes, I have worked with MSTSCAX and it's interfaces.
Now, what is your question/problem ?

i use IMsTscAx control to connect to the TS Server.
setting valid server name and so on i finnaly call connect method. he return s_ok. but exploring other property's values i find that startconnected property is false - thats mean that control is not trying to connect. as a sequel connected property is false too.
what do i do wrong?

Unfortunately I cannot give my e-mail address, and I don't use ICQ.
First, go and download and install the latest version of the Microsoft RDP Client ActiveX Control. You can find it here[^]. After the control is installed, browse to the directory where you installed it. You can find a 'default.htm' test page there. Open it up on your browser, and you'll get a test page. Use this test page to connect to the TS client like you normally would. If the connection fails, the problem resides in the TS Server, and not in your end.
After installing, if you have Windows XP, you'll have two RDP Client controls. The one we just installed is called 'Microsoft RDP Client (redist)'. Use OLE/COM Viewer tool to browse through it's type library.
When/If the connection was succesfull, the control is tested and you can use the it anywhere you need. I have created a small example application that connects to a server IP you provide it with, and displays the login screen. The code is commented heavily, and the interesting parts are in the Connect and Disconnect buttons click handlers. Works smoothly for me. The example application is not very usable, as the display area is very small. But it'll show you how it's done. Note that in order to disconnect my application from the TS Server, you must first click outside the RDP Desktop screen, then click on Disconnect button.
You can download the source code and the example application from http://www.tpu.fi/~t1akeski/TSClient.zip. It is written with VC++ .Net 2003.
As for the problem you described, then an answer is written to MSDN:
The control connects asynchronously, so a return from a Connect call indicates only that the connection has been initiated successfully, not that it has been completed. You should respond to events on the IMsTscAxEvents interface to determine when the control has successfully connected (or has been disconnected).

any ideas?

This is not possible in VC++, because the IMsTscNonScriptable interface that is required to set the password for automatic logon is not exposed by the Microsoft RDP Client Control. This is a design issue by Microsoft, they made it this way.
It is possible in VB .Net, because it doesn't care whether an interface is exposed or not. However, using it also requires some specific settings in-place for the Terminal Server. For more information, read the Knowledge Base -article Q281417 here[^].
Unfortunately I cannot help you any forwards. The easiest way to directly execute a program in a Terminal Services environment is to use the Remote Desktop Connection program and it's templates, which support automatically logging on and executing an application when the TS connection is opened.

Annti, sorri. this question is not already actual. i'd already implemented it last evening.
and its possible. IMsTscNonScriptable interface is exposing. i'd acquaint with msrdp documentation and found the way to do it.
bytheway. vc++ is more powerfull than vb, so if it posiible there then it is total-lot possible in vc++ 
if u r interested mail me.

Hello, Can I refer to your code about the client of MSTSCAX ActiveX Ctrl.
In vb, I can do it easily
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
AxMsRdpClient71.Server = "172.16.112.33"
AxMsRdpClient71.UserName = "gui.rs"
AxMsRdpClient71.AdvancedSettings6.ClearTextPassword = "1"
AxMsRdpClient71.Connect()
End Sub
but in vc, I cant create a member for activex mstscax.

Hello Antti !!!
1.) The URL you provided doesn't work now. I'm also trying to make an activeX COM client for RDP connections. Can you please upload the code again & send the URL ?
2.) How can we create the instance pointer of IMsTscAx interface class?
code:-
void Connect()
{//*pInterface pointer will be used to call the methods to make rdp connection
IMsTscAx *pInterface;
CLSID clsid = __uuidof(MSTSCLib::MsTscAx);
IID iid = __uuidof(MSTSCLib::IMsTscAx);
HRESULT hrInterface=CoCreateInstance(clsid,NULL,CLSCTX_INPROC_SERVER,iid,void**)&pInterface);
/* but here pInterface becomes NULL because clsid = __uuidof(MSTSCLib::MsTscAx)is not a valid value but if I use clsid = __uuidof(MSTSCLib::MsRdpClient2) then clsid comes out to a valid value {CLSID_MicrosoftRDP Client Control (redist)} and interface pointer pInterface also gets filled n initialized, but then after setting all the rdp connection parameters, HRESULT hrConnect = pInterface->Connect() doesn't work though hrConnect gives success message. */
<pre>pInterface->PutDomain("spider.net");
pInterface->PutServer("192.168.10.195");
HRESULT hrConnect = pInterface->Connect();
}
Is there any other way(besides done in my code) to fill this interface pointer *pInterface ?? Please help.
Regards,
Lokesh

Hi Lokesh,
It's been a while since I dealt with this issue. But the URL works just fine. I just tested it. Might've been a hiccup at the Microsoft end, or perhaps you cannot access it for some other reason? But rest assured, the website is there.
I can't upload the code. I would be violating Microsoft's ToS. Please visit the web-site in the link.
As for your second question, you can't. The IMsTscAx is an interface exposed by the Remote Desktop ActiveX Control. What you need to do is instantiate the RDAC itself, and query it for the IMsTscAx interface. I can't remember the RDAC's CLSID value out of the top of my head, so you'll need to use the OLE/COM Object Browser tool in order to determine it. It might be the CLSID_MsRdpClient2 you discovered) Once you have the CLSID, call CoCreateInstance with it and query for the target interface. If this fails, ask the object for IUnknown first and use the returned pointer to query for the IMsTscAx. All COM objects support IUnknown, so if you have the CLSID correct, you should be able to get it at least. If the IMsTscAx interface query returns a failure through IUnknown::QueryInterface, at least you'll have more details on why and how it fails.
As for the reasons why the 'Connect' call refuses to work, I can't say. There are numerous reasons why a Remote Desktop connection may fail, and not all of them are related directly to code. Perhaps the service is disabled? Perhaps access is prohibited? You should first try to connect to the Remote Desktop service by manually using the RDS software (Found in Start -> Programs -> Accessories -> Remote Desktop Connection). If you can connect manually to the host computer, then try the code-wise approach.
Regards,
Antti

I need a windows control that has multiple radio buttons in a row, to allow the user to select and deselect a number of options specific to a single item.
Does this exist, or is the only way to roll my own?
If I have to roll my own is the a good article to look at?
Thanks

Are you talking about having a row of radio buttons, from which the user can select one ?
Then the answer is control grouping. Take any dialog template. Then place the row of radio buttons there. Now, go to the Tab Order option, and make sure that the radio buttons are set into an ascending order so that the first radio button has and index, say, 6, the next is 7 and so on, until the end of the row. Then go to the properties of the first radio button, and check the option 'Group'. All other buttons must NOT have the Group option set.
The Group option works so that the first control in the tab order that has the Group option set becomes the first member of the group. All adjacent controls (in the tab order) of similar type belong to the same group until a) another similar control with the group option set is met or b) a different type of control is met.
To access this group code-wise, add a member variable to the first radio button control, and take it's value. The value returned is a zero-based index on the radio button that is selected. Like, it's 0 if the first one is selected, 1 if the second and so on..
For a good example, go here[^].
Remember that the radio buttons can be vertically, horizontally or diagonally placed on the dialog. The tab order determines how they are grouped, not their physical position.
