Does anyone know how big a .NET app can be. I'm interested, if there is a limit of the size of an application ..
for example, assume that there is no hardware limit - there are few/enough GBs of RAM (if not, the os will use the virtual ram) - available .. and now i'm filling in a for loop (for example) an array ...
Does there exist any limit or restrictions which are known or defined, other then "not enough RAM or similar"?
Im interested if the app will "crash" after it becomes bigger then (for example) 1GB?
Does anyone know that? If not, what is the best way to check it?
Im not sure if that above is clear enough, but i hope it is.
I'm thankful for every answer!

I'd say you'll never reach the limit if there's one, so why bother?

Depending on what your doing and using, an array has an index limit of 2,147,483,647 on a 32-bit processor...

As any process also .NET apps have some limitations in size.
On an normal Windows (not 64 bit) this limit is somewhere beyond 1 GB (in one of my projects I needed an decimal array with 80 million elements and I still know it was very near to the limit).
This is even simple to check: Just make an test app and create some kind of big array and make it bigger until the OutOfMemoryException comes

maybe i'll write an app to test this.

hai
i am new to .Net
plz any one explains what is assembly?
and unboxing concept?
thanx..
|
|
|
|
|
An assembly basically is an executable file.
Boxing means "packing" a value type into a reference type. Unboxing is the "unpacking" of the value type.
(I hope I got that right...)

Hey, I am just wondering is there a way to turn off interpolating when drawing completely?
I am trying to draw an image in 2x size.
At the moment I am setting the Interpolating property to: System.Drawing.Drawing2D.InterpolationMode.NearestNeighbor
This is the "lowest" setting I can find for it. With this it's fine, except there is a line in rightmost column & bottommost row. I tried to fix the solution by resizing the image adding 1 pixel to the width, and one to the height, and then I copied leftmost column to the rightmost, and topmost row to the bottommost. This works fine, but I am getting a feeling that this isn't a good way to solve this. There [b]has[/b] (I hope at least) to be a way to turn the interpolating off.
If there's not, I want to know if there's a better solution? Maybe I should write my own DrawImage method, but I am quite unsure which would be the best way to do this. Using SetPixel() and GetPixel() of Bitmap class would most likely be too slow. I could use LockBits() to retrieve the pixel data, and then play around a bit to copy the pixels to the destination Graphics. I want to stay away from "unsafe" code, as long as there is good enough design solution available.
Thanks.

Unless you draw your image in it's exact size (or a multiple of its size) interpolation *must* occur. If you're drawing the exact size, there's no interpolation.

Does anyone know of a good reference for this task?
I'm finally able to pull my development head out of the sand and look at the VS 2005 (beta 2), and I was blown away by the added complexity of doing something as simple as putting a few fields on a form (what ever happened to dialogs???) and then display a message. (AfxMessageBox? What's that??????)

If by C++.net you mean managed C++, I would start with a .NET introduction.
Most of the language-specific aspects of .NET documentation (i.e. books) aren't geared much towards C++--they concentrate on C# or VB.

I noticed some very stange values coming back from some calculations in a datatable and decided to investigate.
Has anyone come across the problem below
?CSng(.51) + 0.01
0.51999999046325684
?CSng(.57) + CSng(1)
1.56999993
I assume this is something to do with the way that the floating point value is held, but I've never seen it before.
I'm using VB.NET to do this, but has anyone else noticed similar behaviour in other flavours of .NET?

Yes, anyone who has done any floating-point calculations on a computer has run into this.
Welcome to floating-point.

Hi! I have an app that communicates over tcp/ip. About 50 people use the app and had no problems launching and executing it.But that was this one person in which the program didn´t launch, it just crashed and the error was:
"No Buffer Space Available -- A socket operation could not be performed because the system ran out of buffer space or the queue was full."
This happens i think when i create a new TcpClient and connect to the server.The strangest thing is that this part is inside a try-catch block to get the socketException Exceptions!!!
Any hints on this?The app runs fine on 50 other pc's but this one.Is it from my app or the pc ( I RATHER BLAME IT ON MICROSOFT ). By the way my socket buffer is 1k long, not MB.
Thx in advance.
Never say never

Hello hello !
This is my problem : I have created a deployment project and at the end of the installation i destroy all temporary files (which are not required for the good working of my program !).
The fact is after destroying the temporary files, when I run my program through a shortcut (that i put with the visual studio configuration project) the windows installer appears (and run some installation...) before my program appears at last !
Who can explain me this funny thing ?
When i don't destroy my 'temp files', I can run my program through my shortcut without problem !!!
Thank you for explanations.
There is no way to happiness, happiness is the way !

I assume you are deleting the files in a custom action that runs at the end of the installation?
The problem is that Windows Installer has no way to log the actions that occur in a custom action. So the installer does not know that you intentionally deleted the files, and it triggers the installer service to run automatically in repair mode because it detects a condition - missing files - that warrants a repair.
There are various workarounds, but all require techniques beyond what you can do within Visual Studio.
The only simple solution is to just leave the files on the target machine. This will prevent the installer from starting automatically in repair mode and does not require complex manual modifications of the msi package...

Hello Graham,
thank you for your answer !
Finally, I've just integrated the creation of the shortcuts in a custom action and not in the .net setup program itself ! So like this it works well !
I wish you a nice week-end,
bye

Hi all,
Is it possible to use typed dataSets in an application for a pocketPC (Compact .Net framework) ?
I have created an assembly containing an XSD. ("MyApplication.Shared.dll")
I have another assembly containting my bussinesscode. ("MyApplication.BussinessCode.dll")
In the click_eventHandler from a button on my mainForm I call a LoadData method from the bussinessCode assembly, which creates an new instance of a typed DataSet based on the XSD (MyApplication.Shared.MyDataSet myDataSet = new ...)
Next the code loads the dataSet with data : myDataSet.ReadXML("file.xml");
File.xml is a valid XML, based on the XSD.
The problem is that on the moment the click_eventHandler makes the call to the LoadData method I get a System.TypeLoadException occured in System.Windows.Forms.dll (application running on the emulator or on a real device makes no difference, both have the same problem.)
When I remove the codelines using the typed dataSet, there is no exception.
When I launge the exe from windows Explorer on my desktop, the application works correctly.
Any Help ???
Greetings,
MPE

I have trouble with reading unicode file.
StreamReader * streamdata = new StreamReader("FileName",System::Text::UnicodeEncoding);
textBoxBibleData->Text = streamdata->ReadLine();
If I do this, I get
error C2275: 'System::Text::UnicodeEncoding' : illegal use of this type as an expression
stdafx.cpp(0) : see declaration of 'System::Text::UnicodeEncoding'
What's wrong? Furthermore, I put
#using <mscorlib.dll>
using namespace System::IO;
using namespace System::Text;
using namespace System::Globalization;
Someone plz help me~

System::Text::UnicodeEncoding is a type, but the StreamReader constructor needs an instance. Try System::Text::Encoding::Unicode.
Stability. What an interesting concept. -- Chris Maunder

If I use System::Text::Encoding::Unicode as an argument, there's no compile error. However, if I run the program the program stops.
I think I need to throw an exception. Does anyone have any other ideas?

I don't see why not. They are simply files, located in your user-profile. My IE ones are in C:\Documents and Settings\%myusername%\Local Settings\Temporary Internet Files. (Substitute your own username for %myusername%).
