GDI+ seems great for rendering little form controls, but as a high performance 2D API, it stinks. Even using memory bitmaps, GDI+ performance is quite slow. Draw 1000 random lines and the application nearly stalls.
Has anyone found out ways or making GDI+ work faster (other then memory bitmap rendering)?
Also, is this the expected performance of GDI+, or will performance significantly improve one VS.Net is released?

I'm using GDI+ as usual ...
I haven't problem with this !

I've seen this problem too.
I've try to paint 10000 random lines in differents manners:
- with DrawLine
- with DrawPath
- with DrawLines
And in all cases, the time spent on the execution is 10 to 20 times
slowly.

Has anyone had the displeasure of using MCCMS (Microsoft Content Management Server)? It is part of the new .NET family of servers but is actually a rebranded version of the NCompass Resolution content management product.
It is great once you have it setup because then authors, publishers etc. can create content at will. However it is the setting up, creating templates and using the API which is a real pain in the ass.
I am curious to hear other peoples opinions on the product, as well as whether you also find it confusing and highly inefficient.
IMHO MS have simple taken NCompass Resolution, rebranded it and are probably right now frantically rewriting most of the product so that it actually works like other MS products and not some 3rd party solution. I hope ver2 is more in line with the .NET family. (Commerce Server 2000 is also like this, rebranded and not up to MS standards.)

Paul,
We have quite a few CMS projects rolling out here in Canada. I'm going to be doing one next month. Is there a specific area that you are having problems with?
BTW... Have you seen the Commerce Server 2002 technology preview? I think you'll find it a little easier to work with.
Cheers!

I am involved in the second CMS roll-out in the United Kingdom (dev back in South Africa). Our partner company is quite close to MS and so they have really evangalised CMS to us and their client.
I don't want to disparage a MS product as I am normally impressed with them (VS.NET for instance is just stunning IMHO) but CMS to me feels strange and rather amateurish.
Have you used the product much with a "real world" website? When I first used it I was happy with it. The samples were simple and easy to understand and I was impressed with the WYSIWIG editing of content. I still am.
It is when you actually start to do more complex websites with include files, proprietry database calls etc. that things become confusing and rather arse-backwards.
My main areas of confusion (which I am slowly getting my head around) are:
- using my own include files: Just found the Shared folder which helps a bit
- CMS's folder structure: CMS should really use a standard virtual directory off of the inetpub\wwwroot folder to remain consistent and integrate easily with Visual Studio and how us ASP coders think
 )
- Folders vs. Channels: Finally understanding it but seems cumbersome and inneficient
Also editing templates is a pain. You have to open Site Builder, right click the template and select Edit Template HTML. Then one edits the HTML and ASP code. Then you save, close the HTML editor, close design pallete and preview the template. If something is not quite right then you have to re-do that whole process.
I also cannot see how CMS is going to work with ASP.NET files.
Some other issues are:
If you are selecting a template to import and you alt-tab to another app (leaving the Site Builder file selector dialog open) to copy a file or two and then try and alt-tab back to Site Builder you can't. You can see Site Builder but it does not respond and checking the alt-tab list shows no Site Builder. You have to End Task Site Builder and then re-open Site Builder.
If you add a resource to the resource gallery it often takes about 5 Global Refreshes before it shows up in the Design Pallete.
My main problem is that I am used to using Visual Studio and a normal IIS folder structure. CMS though does not follow any of the same standards or ideas. It is a great product once setup, no doubt about it. But setting it up, creating templates etc. is a mission. It does feel like a product that MS have simply bought and rebranded.
Bottom line? It is a case of throwing the ASP manual out of the window and learning a very different way of creating a website. The template creation side of CMS should have been kept cosistent with normal web site creation.
BTW... Have you seen the Commerce Server 2002 technology preview? I think you'll find it a little easier to work with
Not yet, all my time lately has been spent figuring out CMS Thanks for the tip though.
Thanks for the response Colin, take care.

Here at the Microsoft PDC, I noticed something in a demo which surprised me a little: If, from a web page, the user downloads and runs a .EXE from a web site, and that .EXE is a .NET managed executable, the user will NOT get a security warning. The .NET program will be "sandboxed" (gee, I thought MS didn't like sandboxing ), so the user is safe.
I like that. I tried it myself -- wrote a .NET exe, which was NOT signed with Authenticode, and then tried downloading it via a web page that looked like this:
Click <a href="foo.exe">here</a>
It worked as I had seen in the demo: foo.exe downloads and runs, with no security warning, but as soon as foo.exe tries to do something "bad," e.g. open a file, a security exception is thrown. Cool. And a bit better than the Java way, because Java applets download inside the IE frame, but .NET exes can open Windows and stuff -- they look like regular client apps.
My questions are:
(1) How does this work? My guess is, IE downloads the EXE, looks at its header and sees that the bit is set indicating it's a .NET EXE, so it knows that it doesn't need to put up a security warning since the CLR will sandbox the program.
(2) Is this a feature of IE6? If I downloaded the EXE in an earlier version of IE, would it work the old way (put up a security warning based on the Authenticode stamp on the EXE)?

Mike,
In your VS.NET Release Candidate that you received at PDC, check out the help for an article called "Security in .NET: Enforce Code Access Rights with the Common Language Runtime". It talks a little about the SAFER initiative and code verification.
Cheers!

That is very very scary. Please tell me there's at least a "Warning: applet window" message.

Yes, there is such a message. Over the app's window, a little "speech balloon" comes up, which says:
.NET Security Information
This application is running in a partially trusted context.
Some functionality in the application may be disabled due to
security restrictions.
This message comes up on each top-level window the program creates. I haven't yet delved into exactly what such a program is and is not allowed to do, but basically it's similar to the sandbox model that Java has. E.g. they can't touch the local file system (except for a small scratch area called IsolatedStorage).

I have seen and heard several references to how you can create relationships between datatables and then produce a dataview on more than one table; however, all of the code samples I can find always call the default view for a single table rather than building a custom view.
Does anyone know where I can find or have and example of a dataview that is based upon more than one datatable.

We have created a web service for our clients. Now we need to additionally allow the clients to call the Web Service from a Unix platform. Any ideas on how this can be accomplished.
Thx.
Mark

Web Services are based on open-standard XML/SOAP. Visual Studio .NET automates the translation from the HTTP-based protocol to a class interface by creating a proxy class. As long as your UNIX clients can do HTTP, then they can see the resulting XML from the call and interpret it. I don't have any specifics for UNIX, but it shouldn't be too hard to find information on XML/SOAP calls.

I think .NET will be great for IT departments, consulting firms, service providers, and the likes. From their press releases, I also think that MS develop .NET with these people in mind.
However, I haven't heard their views on .NET for commercial application development.
Personally, I don't think .NET haven't much to offer on this area except improve time-to-market. However, .NET runtime will surely penalize apps runtime performance.
Any views on this one?
|
|
|
|

The Common Language Runtime offers some great stories around performance (Just-In-Time and pre-compiled apps). As far as commercial applications, it is already being used in some earlier adopters. Crystal Decisions is one of the first out the door with their version of Crystal Reports built on .NET. Expect to see a bunch more out soon now that the Release Candidate is available.

I actually had a lot of trouble with the DVD getting read at all, although I admit I've not used it yet ( still waiting for a book to arrive ). What do you mean by reduced functionality ? It's a beta, so it wouldn't surprise me if some things do not work, but unless you're specific about what you mean, any problems with installing etc., I don't see how anyone can hope to help you.

Sorry for the late reply. There are 2 issues that I can think of that you may be referring to:
1 - RC2 had a bug in the VBScript. There is a download available from the VS.Net webpage on MSDN.
2 - The time-limit built-in. If you do an update from the VS help menu, MS has an SP that fixes that.

Hi everybody,
I tried to install the .net framework on my Windows 2000 Server SP2. But the installation of the Windows installer V 2.0 crashed. I have tried everything to fix this problem with register and unregister of msiexec.exe and regsvr32 msi.dll but nothing helped. I really would like to install the .net framework, but if I not can circumvent this problem with the Windows Installer this will not be possible. Does anybody know why the upgrade of the Windows Installer V1.1 to Version 2.0 can be done correctly ?

Hi people !,
help please !! how can you facilitate Web Service to Windows Forms communication ? (or at the least, what's it called ?)
what i mean is, suppose you invoke a Web Service function that should update a TextBox on separate Windows Forms application . they are both on the same machine.
thanks ! any help would be greatly appreciated !!!!
