Doug,
Despite what David has said, I find the biggest problem with cross-posting is that it's really annoying when you spend time answering someone in one forum and then find that someone else has already given them the exact same answer somewhere else.
It's usually fair to say that people will visit every forum that applies to them and most questions do fall quite heavily into one category - yours for example is clearly of no interest to people who don't look at ADO.NET, despite the fact that it has C++ connections.
[EDIT]What the hell was I thinking about here? This sentence should have read "people who don't look at MC++, despite the fact that it has ADO.NET connections"!!![/EDIT]
If you do find that you don't get a response in the obvious forum and you start thinking you might have done better elsewhere, post a message in the other forum saying "Please take a look at this question in the ADO.NET forum:" and offering a link to the original message. That will usually draw a lot less scorn than cross posting.
David's suggestion that it's a good idea to post in the C++ forum because most people go there is a strange one.
For one thing, I'd imagine an MC++/ADO.NET question like yours would draw a few complaints in the C++ forum. For another, contrary to popular opinion, some people don't visit the C++ forum very often.
I for one find that I can't offer a lot of help there so I usually only go there when I want to ask a question. I make up for it by answering questions in the C# and Web Dev forums where I know a little bit more

You are probably not working for a real world project, do you ?

Unfortunately you need the .net framework in order to run apps. The framework has not been ported to the Mac. However, the framework is currently being ported to Linux via www.go-mono.com project which is rumoured to be porting it to the mac once they finsh. I've also heard that Corel was working on this for the Mac but who knows. Anyway, your app will not run.

ez2,
thanks for the reply. i know i need the framework to run the .NET i just wasn't sure if the .NET would like the Mac OS. i didn't think it would but you never know there might have been a work around somewhere out on the net. it wasn't a big issue. i generally find any real company doing any real business are working on pc's.
anyways i appreciate the response it confirms what i pretty well knew already.
thanks.

Before you say such things, you should know that this workforce decided a couple of weeks ago that making the System.Windows.Forms run with native code was just too hard, so they have decided to use a WIN32 emulator instead. Unfortunately, this emulator is known as something unreliable, bugged, uncomplete, ...
Open your eyes, and read : "System.Windows.Forms is currently being implemented using the Win32 API, we will be using WineLib on Unix systems to emulate the Win32 API. Although the original plans were to use Gtk on X and Cocoa on MacOS X, it would be very hard to emulate the event model in which some Winforms applications depend, and it would be very hard to implement the Wndproc method. "
This is an excerpt from go-mono[^].

What does that have to do with anything?
IMHO the popularity of Interop is far more of an obstacle to easy crossplatform ports than which library Mono is using to implement winforms.

How do you show winforms then on Unix ? Surely the BSTR to String interop marshalling helps you a lot.  
How low can you go ?

If I programmatiacally want to determine whether .NET framework is installed on a computer and if so what version of .NET, how do I do this?
The project can not use .NET naturally since it also has to run on computers where .NET has not yet been installed. I've looked in the registry and found that I can use "RegOpenKeyEx()" on the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\policy\v1.0", but there must be a better way, since this call will fail if the user is running v1.1 . So how can I decide if and what version of .NET is installed on a computer?

If you app is being accessed or downloaded from the web, you can check the user agent of the request object. .Net adds the clr and version number to the user agent. Check out http://www.asp.net/webmatrix/download.aspx?tabindex=4 download section which uses the user agent to detect whether or not .net is installed. It's quick and simple. Hope this helps.

On the client-side, check out whether mscoree.dll exists (it's in <winsysdir>). That's the first thing a .NET app loads (to host the CLR).
Regarding the .NET version, you can lookup the registry : HKLM\Software\Microsoft\NET Framework Setup\Product\xxx with values defined as for instance :
Package="Full"
ProductLanguage="1033"
Version="v1.0.3705"
Version is like this
1 : major
0 : minor
3705 : build

You could also check the for the existence of the path:
%windir%\Microsoft.NET\Framework\v1.0.3705

Hi, i want to develop an application that use scriptable configuration file, like Macromedia Dreamweaver MX.
In Dreamweaver MX you can modify every dialog boxes just in modify a HTML/Javascript source. A windows dialog box is an HTML form, and you can't see the difference.
I just want to know what is this technology ? Is it .NET who give this capacity to do that ? A library ? or is Macromedia who invent that ?
Thank you for your answer.

How do I create an off screen graphics object?
Basically, I want to draw some stuff to an off screen bitmap and them blt the lot to the main window graphics object.
This is NOT for double buffering. I need to be able to compose a small scene using transparency and then blt the translarent bitmap over the main screen which also has been drawn onto.
Any ideas gratefully accepted!
Pete

The System.Drawing namespace is full of stuff for this kind of thing. Between the Bitmap, Image and Graphics objects, you should be pretty well sorted.

Hi. Thanks for the reply.
Yeah, I've already got a lot of drawing going on, but I'm just using the Pain(t) events Graphics object for now and I cant find anything that will give ne a graphics object pointing to an off screen buffer or Bitmap...
?

Just create a Bitmap object, using whichever of its multitude of constructors is most use for you, then if you need a Graphics object use Graphics.FromImage(MyBitmap).

You beauty!
Have now got some piss simple test code working. I didn't even think to look through the static members of the Graphics class.
For anyone else trying this. Heres some Very simple code...
Thanks
Pete
private void ctlSoundScene_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
Bitmap oBitmap = new Bitmap(100, 100 ,e.Graphics);
Graphics oBuffer = Graphics.FromImage(oBitmap);
oBuffer.FillRectangle(new SolidBrush(Color.DarkMagenta), 10,10,30,30);
e.Graphics.DrawImage(oBitmap, 10,10);

Hi.
In my organisation we want to run an application from a server on the co-workers computers when they log-on to the local intranet, to register that they have loged-on, set the printer connections and so on. In order to be able to do this we want to set the permission level on the machines for the Local Intranet to FullTrust.
I'm trying to create an application that installed locally will do this. I have been able to create a new child codegroup that gives FullTrust to the directory where the inlogg-application is situated, but efforts changing the permission set for the LocalIntranet_Zone is so far without success.
The sample code below shows what I have done:
penumLevels=SecurityManager::PolicyHierarchy();
while (penumLevels->MoveNext())
{
try
{
pPolLevel = __try_cast <policylevel*> (penumLevels->Current);
}
catch(System::InvalidCastException* pcatchException)
{
MessageBox::Show(pcatchException->get_Message());
}
// Positioning at root level
pGroup =pPolLevel->RootCodeGroup;
// Find Machine Level Policy
pstrTmp=pPolLevel->Label->ToString();
if ( pstrTmp->Compare(pstrTmp,"Machine")==0)
{
//Find All Code codegroup
pstrTmp=pGroup->MembershipCondition->ToString();
if(pstrTmp->Compare(pstrTmp,"All code")==0)
{
//Loop through the children to find LocalIntranet_Zone
pList=pGroup->get_Children();
sCount=pList->get_Count();
for(sIndex=0;sIndex<scount;sindex++)
{
="" try
="" pchildgroup="__try_cast" <unioncodegroup*="">(pList->get_Item(sIndex));
}
catch(System::InvalidCastException* pcatchException)
{
MessageBox::Show(pcatchException->get_Message());
}
pstrTmp=pChildGroup->get_Name();
if(pstrTmp->Compare(pstrTmp,"LocalIntranet_Zone")==0)
{
//Getting the FullTrust permission set
pFullPerm=pPolLevel->GetNamedPermissionSet("FullTrust");
//Checking what is the present permission set
pstrTmp=pChildGroup->get_PermissionSetName();
//Create a new policy statement with the desired trust level
Security::Policy::PolicyStatement *pPolicy;
pPolicy=new Security::Policy::PolicyStatement(pFullPerm);
//Set the new policy
pChildGroup->set_PolicyStatement(pPolicy);
//And save changes System::Security::SecurityManager::SavePolicy();
//And again checking what the permission set is
//to make sure it has been changed
pstrTmp=pChildGroup->get_PermissionSetName();
}
}
}
}
}
When I check the name of the permission set the second time it is FullTrust, quite as I want it to only this does not have any impact on the real setting, the local intranet does still not have FullTrust status. Is there something preventing the level from being changed to a higher trustee level or am I missing something?
Best regards
