Hi folks,
I recently stumbled about an annoying problem while designing components:
It just seems impossible to me to create a control that allows other controls to be put upon at designtime.
As far as I understood the MSDN every control derived from UserControl has the ability to support child controls. That works ok when adding controls simply by code but I can't add them using the designer.
I tried to set AllowDrop to true and played around with the DragDrop events. The problem is I didn't found a way to extract the control from the DragEventArgs parameter (if it is there at all).
Would be great if anybody could tell me how to create a control that act like the GroupBox for example, including visual component adding.
Thanks in advance,
Matthias

Is there any system for loose coupling of the GUI parts like Doc/View or MVC in .NET?

I could really use some professional help here(besides the psychiatric type).
I am an ASP / Perl developer who has dabbled in XML and ASP.NET a little bit.
My boss in his infinite wisdom has decided that because of my "dabbling" I can develop an ASP.NET / XML application and I have no idea what i am doing. Oh and before I forget, this application is being presented to the client on January 02, 2002.
What I am requesting is some ideas on how to put this thing together. I have begun reading several books on .NET and XML as well as going through this site and others looking for code samples to get familiar with how it works but I need lots more.
Here are the general specs on the application:
This application is going to automatically (4 times a day and also manually) pull information out of a SQL 2000 database and create a series of complete static websites from the information it pulls.
There is to be a series of control panels that depending on user access level will allow the user to add new articles or advertisements to the database; allow the user to renew the term of their advertising contract, allow them to update their personal data, and the admin will be able to launch the static conversion process as well as add new "domains" to the process. This process will be able to handle the complete creation and ftp upload of a minimum of 25 and a max of about 100 complete sites.
As if that wasn't enough, there will be a separate site that advertisers will be able to submit new advertising to this series of sites.
That, is of course a very brief and ultra high-level description but I am hoping that is enough info to get the proverbial juices flowing with suggestions / ideas for what I can do with ASP.NET / Web Services / XML to not only get this done on time but also in a logical order.
Thank you in advance for your help with this monster.

Everyone,
I have downloaded MSSoapToolKit 2.0 and run the sampleas. But on my office's computer, have one puzzle: while I do Calc sample by "Using a High Level API for SOAP Messages", here has following problem:
?mSoapClient.detail
Client:Sending the Soap message failed or no recognizable response was received HRESULT=0x800A13BE - Client:Connector - Invalid Http method. HRESULT=0x800A13BE
?mSoapClient.faultstring
Client: Connector - Invalid Http method.
On the other hand, I made it by "Using a Low Level API for SOAP Messages", all right. And on my home computer, all two methods are profect. Anyone met this before? Thank you very much.

I am a senior engineer with a major insurance company in NYC and I am extremely well versed in MFC/ATL/COM.
For two years now, I've been reading about .Net, and nothing, I mean NOTHING, has convinced me that it is anything more than a new Microsoft "flavor of the month". With all the hype surrounding .Net, I need someone to convince me that learning it WILL be the worth my time and effort. Forget all of Microsoft's rhetoric about betting the company, etc., I need someone to tell me why .Net is better...
Writing >>>good<<< code used to be an artform. Some of us are really good at it; most out there are not. It looks to me as if Microsoft is now taking the hand holding approach to the extreme. Writing something in MFC? There are now wizards that do just about everything. What about ATL/COM? No more IDL. What happened to DESIGNING an interface before coding it... Maybe I'm just an old dinosaur who actually enjoys his craft and who thinks writing concise, highly-optimized code is fast becoming a lost art. I can't be the only one who feels this way...
I can hear you youngsters out there now... "Resistance is futile, you WILL be assimilated!"
Am I really becoming extinct? Must I be dragged in kicking and screaming? Please, someone, convince me that .Net IS the future.

I am not going to try and convince you that .NET is better, you have already convinced yourself that it isn't.

Why can't you do this with VS.NET (.NET is the framework)? Sure there are wizards and helpers but you don't have to use them. Office comes with a million Wizards, I have probably used at most one or two of them.
Carry on hand coding just like all serious developers will and do, no harm done if MS choose to help out newbies or developers with mis-aligned deadlines.

MS are betting the company on it, if you don't go .NET you will be left behind. Till they loose dominance you can't argue much about it.

I find that the design pattern for Dispose() is quite tricky, and I think many programmers are going to get it wrong. (For details, look for an article entitled "Implementing a Dispose Method" in the .NET docs.)
This is a real shame, because in so many ways C# and .NET take common but complicated programming tasks and make them really straightforward (and, in fact, pretty hard to mess up). But in the case of implementing Dispose() in your own classes, C#/.NET actually make it pretty hard to get it right.
I do understand the suggested implementation, and I understand the reasons for the different pieces of it. And, no, I don't have any brilliant suggestions for how to make it better; that would take more thinking than I want to put into it at the moment. All I'm saying is, I wish they had come up with a better, cleaner way to do it -- e.g. some language feature built into C# and VB.NET etc. which made it really easy to "get it right."

We've had the Beta1 version of VS.NET installed for some time and yesterday I got the time to upgrade to the Candidate Release version. I started with uninstalling the old version, but then I f***ed it up a bit since I tried doing the installation remotely, through Windows Terminal Server. I finally managed to install the CR on the server late in the afternoon. I started a few projects and they seemed to load correctly.
Today as I tried to run the latest project I've been working on (ASP.NET Web application) , it claims it can not find System.Web, or one of its dependencies. I checked through the Temporary ASP.NET Files folder under winnt... and found that it had a subfolder for each framework version. When comparing the project files under the new version with those under the old version, I found that some files were missing in the new version, probably they should be created when the project is started.
I tried creating a new Web Application and start it. it ran without problems. When comparing again the temporary files in these three projects, i noticed that wheras the old version of my project had a file called __fusion__.info, both new projects had __AssemblyInfo__.ini instead. (I found it in the most "leafed" folder, the most nested folder under each project.)
I hope you are able to help me, I would like to learn how to use old projects.

When trying to compile a Beta2 project in RC1 I get this error:
C:\Misc Projects\VSNET Samples\NetSamples\PeerChat\PeerChat.resx Resource transformation for file 'PeerChat.resx' failed. Invalid ResX input.
I get that error for every resource file, any ideas? Any help is greatly appreciated.
Thanks.

I will post this on the .NET forum as well but I thought all the Loungers would be interested as it raises a lot of fundamental issues (also it made me go WOW).
Death of the Browser? on MSDN. Very interesting article on the automated Internet deployment of .NET applications, with some real examples and discussion.
I cannot really explain it without repeating the article so just read it and most importantly get that block of VB code (yes VB, just run it) and run it (you need VS.NET Beta 2 or at least the .NET framework and Notepad). I was pretty damned amazed.
Has anyone tried this out in a "semi" real application?

I can't find a substitute for SetROP2.
I want to draw in inverted color but I don't know how to.
With GDI I can use SetROP2 function to set how colors are
combined with the background, but I don't see something like that in GDI+.
Anyone can help me?

I was just browsing the MSDN subscription downloads and came across Visual J# NET Beta 1. It looks like it's been around since Oct 10. Does anyone know if there are any links/info about this?

Not only is the .Net a bloated (1.2 Gb!) distribution
[.Net Framework + Visual Studio .Net] but the design principles behind the product are completely motivated by Microsoft's continued need to dominate the technogolies that it perceives drive the marketplace.
C# is an obvious rip-off of Java. Does Microsoft think I'm going to continually invest my valuable lifespan learning "new" languages with no tangible benefits over existing languages? C# is proprietary and flys in the face of a multi-platform advantage enjoyed by Java.
VB is horribly incompatible with VB 6. Project conversion from VB6 to VB7 is verrrrry slow (almost 1/2 hour to convert a simple project with several forms) and results in hundreds of errors that much be attended to manually due to changes in VB.
Each change is a reference to some documentation link that must be visited and absorbed.
Tired of going down the same roads...

did you forget? Java is owned by Sun.
VB is horribly incompatible with VB 6.
VB?? talking about proprietary... at least MS is submitting C# to a standards body (which Sun won't do with Java and MS would never do with VB).

Java execution support is at least supported on a variety of operating systems and browsers whereas C# requires the Common Execution environment that Microsoft is not likely to make available elsewhere. I guess by "proprietary", I mean "limiting".
Yeah, VB is proprietary but my point there was about compatibility.

There is the mono project that will make .NET available to LINUX.
http://www.linuxdevices.com/news/NS6609104471.html
Javas primary goal was to build OS independent client software. How many commercial client apps written in Java do you know.
With .NET you will have some powerful libraries (Forms, etc) to get your job done in a productive manner.
All I need is a roadmap and then I might be able to find a clue.

If you're a regular you'll know I have little nice to say about C#/.NET. That being the case:
C# is proprietary and flys in the face of a multi-platform advantage enjoyed by Java.
You came from /., right ? Only there is it acceptable for Sun to have a proprietary language, but not M$.
Java wasn't exactly a new idea in any case.
