Re: VS.NET Classview issue Travis D. Mathison9-Mar-02 9:45 Travis D. Mathison 9-Mar-02 9:45  Yep. I've pinned it down to only occuring in C++ projects when the outlining feature is enabled .. I have disabled outlining for my VC++ .NET projects and the classview behaves right. Everybody is obviously not having this problem, however I hope that Microsoft finds a fix for the few of us by the first SP. Travis D.

Re: VS.NET Classview issue Rick Crone14-Mar-02 9:25 Rick Crone 14-Mar-02 9:25  I no I'm getting away from what this thread started out on... but. I see you really are using VC++ 7.0. When I create a dialog in VC++ 7.0 I get a HTML version as well as the resource and DoModal seems to use them both. Have you seen any of this? Re: VS.NET Classview issue Travis D. Mathison14-Mar-02 9:34 Travis D. Mathison 14-Mar-02 9:34  Yeah, by default the class CHTMLDialog is used instead of CDialog. You can ofcourse change this to CDialog when you first create the class for the dialog. I guess it's Microsoft's way of trying to push people to using the HTML type dialog as it offers the possibility of richer dialogs etc. ... Travis D.

Oh... then if I use the html code do I just delete the buttons off the resource so I don't have the buttons showing up twice? If I go with CHTMLDialog can I still use the graphic interface for adding controls to the html? Re: VS.NET Classview issue Travis D. Mathison14-Mar-02 9:47 Travis D. Mathison 14-Mar-02 9:47  You can indeed delete the buttons off the resource. I haven't fooled around with CHTMLDialog too much yet .. this next project I'm doing will have me doing it though.

Re: VS.NET Classview issue dazinith13-Mar-02 6:40 dazinith 13-Mar-02 6:40  Yah i just encountered the same pain in the butt.. turn off the outlining (which is one of the coolest features ).. and keep your fingers crossed that it will work one day soon.. it works when outlining is on, but only the first time you double click on the class/function.. doesn't seem to affect double clicking on variables, but that looks at the .h not the .cpp.. anyone got a phone number for a MS developer to make sure they are workin on it? -dz Re: VS.NET Classview issue Travis D. Mathison13-Mar-02 6:48 Travis D. Mathison 13-Mar-02 6:48  Yep, it is a problem with VC++ .NET and outlining .. I'm hopeing as well it gets to Microsoft and the issue is rectified with first SP Travis D. Mathison --- --- After three days without programming, life becomes meaningless ... User Control flashgordonmjg5-Mar-02 14:51 flashgordonmjg 5-Mar-02 14:51  User Controls: I have created a user control, simple datagrid, using code-behind. In my .ascx file, I used <%@ Control Language="c#" CodeBehind="RealEstateSummary.ascx.cs" AutoEventWireup="false" Inherits="ETECH.RealEstateSummary" %> and in the .cs I inherited from the UserControl Class using the Namespace ETECH. Ok...I then created a simple .aspx file that contains the following:<%@ Register Tagprefix="MYETECH" Namespace="ETECH" Assembly="ETECH" %>. I don't want to use the SRC attribute. My goal is to "use" it from the ETECH.DLL and not the SRC. Upon execution I get the following message. I know the compiler found the control but I don't understand why it won't create the object to use in my .aspx page. Can anyone help me? The reason for using .dll is so that other "projects" can use the .DLL by using reference thus using the control without supplying the code. ...Sorry for the stupid question!

On line 146 of realestatesummary.ascx.cs you are using the object that is the culprit. Check in your code and make sure that somewhere you are assigning to that variable.

Mathison 4-Mar-02 14:26  I'm sure this is a question many people have had and asked before, but I haven't seen or heard the answer. Is there an equivelent feature for the VC++ 6.0 ClassWizard in VS.NET? I've seen how you can do the Add->Function, Add->Variable, etc. But that is obviously tedius if your adding a lot and I know it's here somewhere .. I've looked through all the Custom tools buttons, etc. Help please .. Travis D. Mathison --- --- After three days without programming, life becomes meaningless ... Re: VS.NET ClassWizard?

Chandram5-Mar-02 21:26 Chandram 5-Mar-02 21:26  Microsoft has just changed the interface. All the features existing in VC 6.0 are also available in VC 7.0 also, but they have just moved to VB kind of interface. You Can Add Function,Variable etc with normal right clicking on Class View. If you want to add some message handlers, or event handlers you need to right click the class and then select its 'properties'. Then you can select the buttons on top for 'Events', 'Messages' handling. It is a real fact that the previous interface in much more simpler than the one existing in VS.NET. Re: VS.NET ClassWizard? Kevin McFarlane26-Mar-02 8:28 Kevin McFarlane 26-Mar-02 8:28  I've not yet looked at VC++ 7, having been concentrating on C#. But I expected that we might run into problems of this sort when we moved to a combined IDE. No doubt, some of the more ambitious of us (not me!)will write a ClassWizard add-in. If not, i expect it will reappear in the next version of VS. Kevin Efficiency issues from VC++6.0 to VC++.NET myenigmaself4-Mar-02 9:51 myenigmaself 4-Mar-02 9:51  I recently ported an old VC++ program from 6.0 to .NET. There were a few issues to begin with, but the only thing that I've changed in the product is that I'm using the Shared DLL option to reference MFC now instead of Static Library. The program builds fine and runs, but when I perform pointer intensive operations the performance in .NET is horrible. We're talking an order of magnitude here. Execution that takes 2 seconds in 6.0 takes 30 seconds in .NET. I've tried all the optimizations I can think of but none of them did anything to increase performance. Should I just stick to 6.0 for now? Why is it so slow? It's unmanaged code so I don't think GC would be affecting performance at all. It seems like it is though. What's the deal? Any input is appreciated. myenigmaself http://myenigmaself.gaiden.com myenigmaself@yahoo.com "If debugging is the process of removing bugs from code, programming must be the process of putting them in."~~Dykstra Re: Efficiency issues from VC++6.0 to VC++.NET Rick Crone14-Mar-02 9:29 Rick Crone 14-Mar-02 9:29  I haven't gotten to performance issues yet. When I create dialogs in VC++ 7.0 they get some HTML code as well as a resource and DoModal() seems to be using both. Are you seeing this? Re: Efficiency issues from VC++6.0 to VC++.NET 16-Mar-02 6:54 16-Mar-02 6:54  my issue was resolved once I moved to release build. debug is a lot slower in vc.net, but release is the same. I even noted a few performance improvements in .net. Need help serializing object in c++ HJB4173-Mar-02 16:16 HJB417 3-Mar-02 16:16  Hi, I'm trying to send an object across a network and I'm trying to implement serialization but I'm not doing it right. I tried searching for tutorials and articles but they're for C#. [Serializable] __gc class FileTransferHeader { public: FileTransferHeader(String* theFileName, Int64 theFileSize); __property Int64 get_Size(){return fileSize;} __property String* get_Name(); private: Char fileName __nogc[256]; Int64 fileSize; Int16 fileNameLength; }; and later in some other class that has a networkstream, and a BinaryFormatter() and an object of type FileTransferHeader named theHeader. I try theBinaryFormatter->Serialize(theNetworkStream, theHeader); and I get an UE. Unhandled Exception: System.Runtime.Serialization.SerializationException: The type $ArrayType$0x2984d64b in Assembly WinsockContinued, Version=1.0.792.39872, Culture=neutral, PublicKeyToken=null is not marked as serializable. -------------------------- One problem with the programmer's mentality is insecurity. This goes deep. An insulting college litany says that failed mathematicians become computer programmers. They are also ridiculed for being nerdy losers, for being too fat or too skinny, and for having few social skills. Most programmers can be spotted easily in a crowd. Nobody really wants to hang out with them. Put thousands of these people in one company and if you can get them to work, you become a billiona How much of .NET is .NET ? 1-Mar-02 16:41 1-Mar-02 16:41  What I am wondering is how much of the .NET framework runs on the CLR. As i am looking through the .NET libraries with ILDASM, it seems most of the heavy processing is delegated to native functions. Everything appears to be just a big wrapper. I am not trying to trash .NET, i am a big fan. I was just wondering if Microsoft doesn't trust their CLR with heavy processing, how do they expect us to. Again, I am no expert. The above assumption is based on a few hours of browsing "System.Drawing.dll". Michael Re: How much of .NET is .NET ? James T. Johnson1-Mar-02 18:13 James T. Johnson 1-Mar-02 18:13  I think what you might be seeing is the fact that GDI+ is distributed as a part of .NET, but it wasn't written for .NET. Thus many of the methods in System.Drawing will be making calls to it. I believe GDI+ has been shipping with the platform SDK since Feb. 2001. A quick glance at System.XML's TextReader's Read method looks to be entirely written in .NET. Then again that was just a quick glance James Sonork ID: 100.11138 - Hasaki "Smile your little smile, take some tea with me awhile. And every day we'll turn another page.

Daniel 'Tak' M.9-Mar-02 9:47 Daniel 'Tak' M. 9-Mar-02 9:47  Think about what you're asking. I think that MS won't rewrite the very native functions just to be "really .NET". Think about such basic functions like CreateProcess, DeleteFile, whatever... they are all wrapped up in .NET, but MS would be stupid to rewrite every function of the WinAPI. If it wouldn't be like this, the .NET Framework (just read that word) would be a complete OS! And what do you exactly mean by "heavy processing"? And why did you browse the System.Drawing.dll for _a few hours_? Hm anyway... You should also compare the .NET Framework to the MFC Framework. Both delegate native stuff to the WinAPI, but still do their own business. .NET surely comes with these so powerful abbreviations like CLR, RCW and whatever - but as usual, they just sound great (which shall not mean that they aren't good things, but MS just pushes them too much and tries to make a big hype on them). What we currently have is not much more than a Framework with some new dlls which bring their own environment for .NET assemblies.
