Hello All:
Can anyone tell me what is the equivalent of using data-aware classes in vb.net? Is it by using dataset classes, i.e by creating *.xsd files? If thats the case how do we "set" the connection, database name etc., at runtime? That is at runtime the user would choose the server/database name.
Thanks for all the help

Hi!
I really need to find a simple way to produce a messagebox, similar to that one would use in a standard windows application before deleting items, saving och closing or whatever.
I used to do this in ASP by using JavaScript on the client (alert...) but I thought I would not have to bother with that now. I've been searching through the SDK several times and still can't find anything usefull. The MessageBox I found seems to work only in Windows applications, not in browsers.
Has anyone seen, heard or done anything that might help me?

ASP.NET is a server-side thing.
To do anything like that you're still going to have to rely on client-side script.
If you want you could roll your own MessageBox component that you could place on your ASPX pages and use like the Windows version, but in the end it'll have to call down to alert as well. I also have no experience in doing such a thing :p

Hi!
Thanks 
I've managed to create a messagebox component but I immediately ran in to further problems: If I want to prompt the user for confirmation or input, how do I get the value back to the server?
As you pointed out I'll be needing to use scripting inside the component, but I still can't figure out how to get the values back from the client immidiately.
I realise you are not experienced in this (nor am I), but I thought I might as well elaborate on my thread so that maybe someone else can supply more information

I think the easiest thing to do, would be to redirect to a confirmed page.
I think this is what hotmail does in its Junk Mail folder's "Empty Folder" command. You click the button to empty the folder, that brings up the confirmation Alert box, without moving to another page.
If you click ok, it then goes to the confirmed (delete all from folder) page. I think if you click cancel it does nothing, but I've never cancelled that dialog before

Hi,
Has anyone installed the RC1 and found that an app wizard form app doesn't run (but compiles ok)?
I've searched through the newsgroups and think that it is something to do with the help - the ICON doesn't show up properly which kinda vaguly confirms this.
I've tried to update the help in RC1 with the MSDN Library help and didn't succeed - anyone any ideas?
Thanks.
Al.

Is it possible to use asp.net with only .net sdk beta2 installed or I need to install the VC7?
Currently I have .net sdk beta 2 installed and the compiler reports an error in .aspx file near the Inherits="something" line.
With the best regards, Vitaly.

This question applies to managed C++, and I think also to C#.
In managed C++, to import a .NET API into C++, you do this:
#using "dllname.dll" The fact that you import the DLL directly, instead of some other file (like a TLB or LIB) implies to me that circular dependencies between managed C++ DLLs are impossible. This concerns me.  Circular dependencies are sometimes useful, as long as they're confined to a single "layer" of the architecture. (Since a layer does not have to be defined as a DLL, but a collection of DLLs that work together.)
How can I make the following example work?
File a.cpp in DLL A does this:
#using "B.dll"
File b.cpp in DLL B does this:
#using "A.dll"
Which one do you compile first? Chicken and egg! I can't find any info about solving this on MSDN.
You don't have this problem when normal (non-.NET) DLLs import from each other, because headers are used at compile time, and because you can generate a A.EXP for A.DLL, then link B.DLL against A.EXP, then go back and link A.DLL against B.LIB.
So, without getting into a long debate about the pros and cons of circular references, how can I solve this problem?
Also, does anyone know if this is a problem in C# as well as managed C++?

Guys,
I'm a new .NET programmer so bear with me and tell if if I'm making the right choices.
The requirements - clients will need to access services from a browser and desktop app (maybe even multiple OS's). The response needs to be fairly fast and the client requests cannot be lost. On the server side, there is some processing and data to be stored in a DB. The data needs to be accesed mostly by using a browser interface.
This is what I'm thinking - clients will access a Web Service via SOAP. The Web Service will feed requests to a MEssage Queue which will queue as well as transact the resuests so that there is no loss. The DB access will be ADO.NET, web site will use ASP.NET and the code will be in C#.
My questions - from what I've read I need to use COM+ managed services. However I'm not clear if .NET has an MSMQ equivalent (is it MessageQueue?) which will give me all these features easily? I haven't used MSMQ before - will this approach give me a low overhead and a high bandwith?
Also the clients will not have .NET framework - to implement them can someone suggest a lightweight and simple C++ library for SOAP calls (the one on this site uses an older SOAP toolkit), or should I use ATL Server generated code instead.
Thanks a lot and please feel free to criticise!

Hi folks,
I just installed the .NET beta 2 on my machine, and attempted to start the IDE. All seems well to begin with until, "Updating Help to reflect recent changes..." then BAM an unhandled exception and the whole application shuts down. (followed by one of those annoying bug reports to MS).
I have successfully installed the beta on other machines! Just wondering if anyone else has experienced the same problem...I couldn't find anything after searching around on msdn.
I am running win2k...

Hello i had that problem when I first installed it on my win2k system. Did you install all the components like it makes you before you install it? If you did and did it by clicking on the server settings link on the button of the setup page and all you did was click install for each of the components, dont do that  follow the instructions for each component before you install it. Then reinstall VS.NET again and it should work....

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

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.
Barry

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.
