With C# you no longer have a callstack beyond your own files. If you are a C++/MFC/ATL coder that's quite a shift, isn't it ?
If you accept this lost of control, that's fine. I don't.

A C# app is a WIN32 app with 100% proprietary stuff. I am not talking about it cross-platform, I am talking about it being documented. Only the surroundings are documented. The combination of interop/attributes/Net framework falls short of documentation, whereas that's exactly what we do in real apps.

Their interest is to take control of your apps by being the providers of an always changing run-time.
By 2004, a basic .Net framework run-time will be part of the OS, and your apps will force customers to buy new computers and hardware just to run it. That's the next level after MS forced us to buy new hardware just to run VS.Net. We developers have never been that much in the "buy-new-hardware" thing. That's what I see.
From my previous post, I have just realized you have skipped the "transaction" part. That's too bad, as it is my main feeling about .Net : great apps will say light of day, but the Object class implementation remains transaction-less, in other words the apps remain unreliable, just like win32 apps.
And I swallow a small raisin.

Using C++ with VS C++.net standard edition.
I can use the .net framework with my C++ application ?
is it what Managed C++ used for ?
I want to use the XmlWriter namespace ( if that's what's it's called ), is it possible ?
Sorry, if it's a really stupid question, but now, I'm really clueless ... I'm taking a couple of hours this afternoon to go buy a book about this ... any good suggestion ? mostly C++, Managed C++ .NET framework ...

No! .NET Framework is not something like MFC.
You cannot use .NET framework in your C++ app.
Managed C++ is not the old C++, there are a lot of differences. .Net Apps work in other than normal Windows app.
Buy a book about .Net framework, what it is and how it works?

You *can* use the .NET framework in your C++ app; and Managed C++ is old C++ with some extensions to it.
Now there are some gotchas to be aware of; one is that an unmanaged class can't directly hold a reference to a managed pointer; the solution is to use the gcroot template class.
That said I recommend, Microsoft Visual C++ .NET Step by Step by Templeman and Olsen.

And there are some C++ features that you cannot use in Managed C++. The main difference is not in language, but in the way it works! The C++ is compiled to the normal x86 code (in MS Windows), and Managed C++ is compiled to MSIL.

Ok! Will you compile it with an ordinary C++ compiler or a Managed C++ compiler?
.Net Framework apps can use API or MFC functions and classes, but you cannot add things from .Net Framework to a normal app as other libraries.

Does anyone know if there is an add-in somewhere that will do syntax highlighting for .IL files, or better yet, an add-in that extends VS to allow the creation of IL-based projects? Or if not, how I could write an add-in to do this?
Thanks

i am tring to develop an application which can install any type of software on any platform with out user interaction in dot net.
First of all my application will learn all events and messages at least one time then it will perform the task on the network on any computer.
is it possible?
if yes how?
can some one provide the helping metrial and links about that?

- 21 MB for the default .Net framework (you have a link in CP homepage)
- 6MB for .Net SP2
- 6MB for MDAC2.7 if the application uses data access
- and depending on the application the user may be required to install IE6.0 (integration with windows forms, etc.).
And I swallow a small raisin.

I have a server that accepts a socket connections and accepts authentication requests in a specific protocol. I want to use this for an ASP.NET authentication. How can I make my ASP.NET app maintain a single connection to this auth server and send authentication requests to it?
I mean a COM object does not seem to be the right way anymore. What is the preferred .NET way of implementing this?

I guess the "proper" .NET way of doing this is to write a class that takes the credentials and performs the authentication against the server. You create this object then once and store it in the Application context. But beware you better build this object with sound multithreading capabilities, otherwise this might become a severe performance bottleneck.

So, what you suggest is that I create the class and initialize it on Application Start and clean it up when the Application quits (I am so new to .NET that I do not know the event names).
ok.. So this class would create multiple threads that maintain the session with my authentication server.
Sounds fine. Now I have to go about designing it.
Thank you
Thomas

Well with multithreaded I meant: I can handle multiple requests at the same time. Not that it creates multiple threads itself.
Think of 50 users hitting your page concurrently. It would be bad if all had to queue up to be authenticated one after another.

I was recently given an assignment which I thought would be very easy, but which is turning out not to be. Our application has a huge, MFC based, activeX control which runs in the browser. We want to use .NET to capture the bulk of this control's behavior on the server side.
However, part of the ActiveX control's behavior involves dragging and dropping icons on to images. We want to do this on the client side. (i.e., capture mousemove events for draging and dropping on the client side browser so that we are not making too many round trips to the server) In other words, we want the UI of the ActiveX control to work exactly as it does now in the browser, only with .NET tools.
Is this possible?
I can get the behavior I want by using .NET Windows forms controls. But Windows forms controls cannot be used in a browser. (At least I can't get them to). I can get some of the behavior useing .NET Web forms controls, but again, the interactivity with a web form control is limited because of the round trip nature of interacting between client and server.
I have come down to the opinion that the answer is to use a light weight ATL ActiveX control containing a web service proxy to communicate with the server. However, my supervisor insists that this is doable with a pure .NET solution. I can't find one.
Any ideas?

I'm having trouble with my MFC applications. Recently I've moved my projects from using the old Visual Studio 6.0 to Visual Studio .NET. I've also changed my operating system from Windows 2000 to Windows XP.
However, after I re-compiled and re-distributed my projects in Visual C++ .NET, I was informed by many of my clients that the applications will not open on their platforms (which they do not have Visual Studio installed). The errors being that there are several DLL files missing, including mfc70.dll and msvcr70.dll and a few others. I've tried to include those DLL files in the distribution packages, but that will increase the size of packages from less than 100K to over 1M. I've also tried to build my application using MFC in a static library instead of in a shared DLL. But that will still increase the size of my applications significantly.
But even with the above solutions, there are still problems. While my applications open on my clients' platform, some of the functionalities are loss (for example, the CFileDialog class doesn't work anymore).
This should be a common problem for many developers, I wonder if there's a better solution. Most of my clients are using Windows 2000 and Windows 98. Only a few of them are using Windows XP.
Thank you to anyone who can give me some advice.

Well if you can you could run VS 6 and VS.NET side-by-side on the same machine.

This is a common problem.
I suggest adding a build using MFC as a static library. As you noted, this creates a large executable, but not nearly as large as the entire DLL package. It will let a client run the software until they can update to the mfc70 DLLs.
I'd also create a distribution with just the shared DLLs (and maybe a token executable to satisfy Microsoft distribution requirements, though I haven't verified if this is needed. I've long been annoyed that Microsoft a) doesn't, in the past at least, update the MFC DLLs with service packs and b) doesn't provide such a package through Windows Update or other obvious place.) This allows those who've already updated their DLLs to simply download the new, smaller, builds.
(Perhaps the installer could download the DLL package if required? Though this is a problem with modem users.)
Finally, you need a multi-boot machine with all the platforms you support.
BTW, several common controls are updated by IE, though I don't know if the file dialog is one of them.
And check your MSDN documentation; [almost?] all common controls have weird version limitations.

who to communicate with a process.lets say there are a number of components on its main window how to pass messages to them,who to passs data to their edit boxes and text areas.
who to get its mainwindow hawndle i tried to get its hwndle like that
Process tmpProcess;
..
tmpProcess.start();
tmpProcess.WaitForInputIdle();
IntPtr hWnd=tmpProcess.MainWindowHandle;
HWND t_hwnd=(HWND)hWnd.ToInt32();
but thats not its main window handle because when i get its rectangle its points are not correct.
what to do if i want to have processes mainwindow hwnd?
i also want to get process main window new handle when its window changes after some processing how to get it?
is there any other way to communicate with process ?
plz provide the helping metrial and related links for that?
i will be very thank full to u.

Hi all. I'm creating a nice little database app that exports things to XML. As a printing solution, I've used XSL to make the XML into XHTML (acronyms are fun!  ). Then I make IE print it with this line:
System.Diagnostics.Process.Start("rundll32.exe", "C:\\WINDOWS\\System32\\mshtml.dll,PrintHTML \"" + tempFilename2 + "\"");
(tempFilename2 is the name of the temporary .html filename I've generated.)
That works great, but only for File > Print. Any ideas on how to to a File > Print Preview or File > Page Setup? Maybe some kind of DDE thing? I dunno...
Someone must have done this before, is why I'm asking. Any help would be nice, thanks!

I suggest to use the WebBrowser control (IE). You can show ther a page preview and a page setup.
The only minus of this workaround is that you must insert the control into your form  ( or maybe it gives you another cool feature )

Is there any way to do this without descending into unmanaged land? I'm using pure C# here. If not, teach me please?
Regarding placement, I can probably just set the width and height to zero.

No problem.
First of all, you need to add WebBrowser support to your project. Right click on the toolbox and select Customize toolbox... On the tab page click Browse... and open shdocvw.dll which is located in the windows\system32 folder.
Now you can draw the control on your form.
The next thing which you must do it to load the document which you want to print.
Object missing = System.Reflection.Missing.Value;
axWebBrowser1.Navigate( "http://www.codeproject.com", ref missing,
ref missing, ref missing, ref missing);
Print
axWebBrowser1.ExecWB( SHDocVw.OLECMDID.OLECMDID_PRINT,
SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DODEFAULT, ref missing, ref missing );
PageSetup
axWebBrowser1.ExecWB( SHDocVw.OLECMDID.OLECMDID_PAGESETUP,
SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DODEFAULT, ref missing, ref missing );
PrintPreview
axWebBrowser1.ExecWB( SHDocVw.OLECMDID.OLECMDID_PRINTPREVIEW,
SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DODEFAULT, ref missing, ref missing );
But be careful. The functions will fail if the document is not fully loaded. You can determine this thorugh NavigateComplete event.
And that's all. If you've got any question simply post it.

This works great, with one problem that I just need a little clarification on to fix. I get an exception the first time I try to do anything with this code, and I guessed that this is because the document is not fully loaded until then, like you said. Now I'm trying to do something like this:
void PrintOperation(EventHandler operationToDo)
{
this.printingBrowser.NavigateComplete2 += operationToDo;
}
And have the EventHandler that's passed to PrintOperation do something like
axWebBrowser1.ExecWB(SHDocVw.OLECMDID.OLECMDID_PRINTPREVIEW, SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DODEFAULT, ref missing, ref missing);
The problem is, it isn't letting me subscribe a vanilla EventHandler to the weird type of event handler NavigateComplete2 is. So, my question is, how could I fire a function upon completion of the navigation?
Thanks so much, this solution is absolutely perfect.
