Add a FastReporting.exe.config file with this content:
<?xml version ="1.0"?>
<configuration>
<startup>
<requiredRuntime safemode="true" imageVersion="v1.0.3705" version="v1.0.3705" />
</startup>
</configuration>
Try some variations.
Why cant you just upgrade the server? Both runtimes should automatically be used for different assemblies.

Upgrade server is still the only one solution for this problem...
I want to find more then one solution (if it exists  ).
Thanks for help.
Good Luck

OK first some easy stuff:
There is a few good articles in April 2003 MSDN on sidebyside execution.
What is happening in your case (afai can figure it out):
1. Server defines an interface
2. Client implements interface
3. Client send inteface to the server
4. Server loads implemetation class. KABOOM!!!
How can this be? Simple, the client has made a reference to the culprit assembly (OleDB in your case, that is new in 1.1). This is however not desirable.
Like I said, installing 1.1 on the server, should automatically resolve these issues. Not doing this, leaves with 3 options:
1. Prevent the client from using "new" libaries. This not however desirable either, although I think the 1.1 compiler can compile for 1.0 compatibilty (this would be nice).
2. Use Remoting. This will be painfull, but will allow you to do more.
3. Compile any source at a single point, e.g. the server.
So I guess its back to the drawing boards for you 
Hope it helps

Does anyone know what factors affect the memory size an object will consume by simply creating a new instance? I know that member-level value-types will consume memory respective of their data type (Int32 consumes 4 bytes, etc.). What about code? Does a class that contains no member variables, but 2000 lines of code consume any memory by simply instantiating a new one?

Generally, no. Since .NET is garbage collected, an instance of a class needs some information for garbage collection and Reflection. IIRC, any Object instance on .NET takes 16 bytes of memory. Another common source of "hidden" memory consumption on OOP environments are virtual methods.

Code shouldnt affect memory.. but if you have declared any virtual functions or derived from some some asbtract base class.. it will as vtable does require some space..
And any static variables also consume.. but only once..

Hi all, hope some one can help here
I have this in C#:
void Save(){}
bool Execute(){}
bool Process()
{
Save();
return Execute();
}
.NET generates the following IL:
.locals init (bool V_0)
IL_0000: ldarg.0
IL_0001: call instance void Save()
IL_0006: ldarg.0
IL_0007: callvirt instance bool Execute()
IL_000c: stloc.0
IL_000d: ldloc.0
IL_000e: ret
Now why does it not do this?
IL_0000: ldarg.0
IL_0001: call instance void Save()
IL_0006: ldarg.0
IL_0007: callvirt instance bool Execute()
IL_000c: ret
I mean this does mean this "do" this same doesnt it? Is there a reason for this behaviour?
Cheers

Theoretically, there’s no good reason to optimize IL code, so I think MS didn’t put too much effort on it. What you showed should be done by the JIT, anyways.

So those 2 are == ? If I write IL manually, can I write it either way then?
What triggered me to ask this , is that method overhead does add up, even though its only about 5ns a call, but call that 100,000 times and it makes sense to inline a method, if possible. It appears the JIT is NOT inlining small methods eg operater overloads. Is there a way to force this without having to manually edit the IL?

==? In theory, yes.
IIRC, the JIT inlines any method with less than 32 IL bytes.
One thing to notice is that the JIT can't inline a virtual method, because the proper method to call is only known at the time of the call, and can change from call to call. BTW, virtual method calls are very expensive.
If you need such degree of control, I suggest you that, before going into ILASM, try managed C++, at least for the critical part. It's not that beautiful, but you still have templates and some form of inline control.
And if the "inline" keyword doesn't help, you can always resort to macros

I didnt spot that 
The whole program will be ported to C (for CS) once I have finished it, so I will keep those things in mind. Maybe make some IL "macros" ?
Thanks for the help
PS: You know of any good (free) IL resources, besides SSCLI and the Tool Developer Guide?

Nope. Actually, I almost only use the good old compile, "let's see in ILDASM" and System.Reflection.Emit documentation.
The cordbg.exe, if you don't mind using a so beautiful interface, is a very good source for finding how the JIT is behaving. It's a bit hard, you need to know x86 ASM (it's not THAT different from IL), generate a Release version with debug info, and use "m JitOptimizations=1" to be sure that JIT will optimize code. Then, debug with that beautiful interface until you reach the call you need to check and use "dis" to see the native instructions.

I tried that, and the debugger skipped the bp with JITOpt 1, so I assume it gets inlined.
Just one final question (I promise):
How does one view the contents of the evaluation stack?

For a long time I've found it convenient to stick pictures I want to share with friends in the wwwroot folder and send a link, rather than sending the whole file to them. It's worked perfectly until now. It seems to have stopped working as soon as I installed the v1.1 Framework, and those who try to access even old content now get a 404 error or an access violation message. I can't even troubleshoot it myself because it works fine for me here. Paul Watson suggested a change to a setting in machine.config, processModel.user = SYSTEM instead of machine, but it didn't help. What else might need to be changed to restore the functionality of the server?
[EDIT]
Thanks to some judicious testing by Paul, the culprit was revealed to be the firewall, installed the same week as the Framework. I hate it when I can't even test things myself!!![/EDIT]

hi there.
i want to write a control for comfortable scrolling on a touchscreen (in fact only two buttons up/down )
now i'm searching for the right method for scrolling the client-area up or down..
any idea?
thanks,
phil

I have System.Windows.Forms.Panel with scroll area
larger than the visible window of the panel and
AutoScroll property on the Panel element set to true.
I have placed few UI elements in the panel that are
outside the visible window of the panel, which needs to
be scrolled to be seen. By default these elements are set
to visible=false.
However, when I toggle the "Visible" property TRUE/FALSE
on the elements that are outside the Panel's visible
window area, the scrollbar provided by
System.Windows.Forms.Panel does show up but it
miscalculates and displaces
the elements in the panel arbitrarily. Did any one run
into this problem. Any workarounds?
Thanks in advance.
Best Regards

How do I take an arbitrary string and UTF8 encode it using System.Text.Encoding.UTF8? I found out how to write strings and how to convert byte data, but not how to convert strings. You'd think this would be easier; maybe I'm missing something.
(I'm using C# by the way).
|
|

|

Use Encoding class in System.Text namespace.
Basically to convert, you first set up encoding. Let's say you have a simple string that you named simpleS. Here is the code that would convert:
Encoding ascii = Encoding.ASCII;
Encoding utf8 = Encoding.UTF8;
byte[] simpleBytes = ascii.GetBytes(simpleS);
byte[] newbytes = Encoding.Encode(ascii, utf8, simpleBytes);
that's it. Key here is static Encode method provided by Encoding class. Once you have the new byte array, you can convert it to char array of utf8 encoded chars.
I hope this is of some help. MSDN documentation also has a very similar example and more stuff on this encoding. I know I used it for the project I worked some time ago.

the method of msdn can only used in the case that you exactly know which
version of framework installed in client machine.
But generally we are in this case that we build a application under
framework1.1 and we don't know the version of framework on client machine.So
it seems the only way that we can do is bet the version of client.My god!!!
I mean we can not let the same copy of 1.1 application run either on framework1.1 or on framework1.0.
Is that true??
lost my way

why don't you just install the 1.1 framework? The two frameworks will run side by side - the only issues I have come across is that 1.0 ASP.NET apps will have to cope wioth the new 1.1 security feature of not allowing tags (and other things) to be placed in element data. i.e "<a" typed="" in="" an="" edit="" box="" will="" throw="" error="" 1.1="" and="" 1.0="" if="" not="" handled="" or="" prepared="" for="" when="" is="" installed.=""

I am sure a lot of you have come across .NET based portals such as IBuySpy and DotNetNuke.
Has anyone else come across other portals based on the .NET framework?
The only other one I have come across is PassagePortal (www.cubiccompass.com).
Any suggestions? And any suggestions to other portal frameworks written in say perl/php/asp/jsp etc
(I am sure there must be a few I have missed in my google searching)

Problem:
I have a really complex class library project that I am sure has an awful lot of redundant code (properties, methods, etc...) that are not used.
I want to be able to generate a report of which methods, properties etc of my object model's classes are referenced throughout the other dependant projects etc.
Question:
Is there an application, perhaps a VS.Net Add In that does this already? If not does anyone have any implementation suggestions before I spend the rest of today reinventing the wheel?

Has anyone used the Bitmapeditor/Imageeditor class in .NET? I looked at it this weekend and could not get it to do anything. My best guess is that you must call the "EditValue" method to run the thing, but that apparently requires having an IServiceProvider. How do you get one of those?

OK, I have basic and probably simple question for you guys...
Here is the situation:
Assuming:
1. I have WinForm Control ("UserControl1") sitting on HTML page, let's assume his name on HTML layout is "ctrl";
2. I have property of that control named "Object" that has set method;
3. My HTML script does the following:
ctrl.Object = ctrl
I'm setting Object property back to the value of "this" on the site of the control.
So, basically, i understand that .NET class through RCW get's converted to IDispatch and then this IDispatch (probably with new CCW) get's passed back to the control.
Now, it's not surprising that after that trip I'm getting
public object Object
{
set
{ m_object = value; <
}
at <> m_object of type "System.__ComObject"....
Now the question: Using what operation could I convert m_object from "System.__ComObject" to my original "UserControl1" type???!!!...
And if you tell me that this is impossible -- your hyped .NET Framework sucks!!!...LOL
Please, don't refference Marshal::CreateWrapperOfType -- cause id doesn't work...
Also, maybe you can give me an example on how I could enumerate WinForm controls on HTML page, from inside one of them and get native .NET classes for each of them -- maybe there is some method -- don't refference "Container" or "Parent" control properties, because they are both nulls (probably because IE is not managed container)...
Anyway, any answer maybe of help...
