The most obvious answer was indeed the answer. My understanding of the .NET framework grew a little today. In order to have the SqlServerCe assembly available, I didn't need to have the .NET Framework 3.5 installed, I need to have Sql Server Mobile 3.5 installed. With that installed, and the flag set in the ASP.NET script I'm now happily manipulating mobile databases. Just for the record though, I'm not trying to write ASP.NET websites using mobile databases, I understand the limitations. I'm using the pages to call from a mobile application.

Hi,
I'm having a problem with writing a file on my desktop using VB.NET ...
I'm in a domain and the problem can be solved by running the program locally.
But I want it to run when I log on to my domain ...
It has something to do with the assemblies !!!
anybody who can help me to fix this problem ?
here is the link to the screenshot

I did it because I think people who know a lot of the .NET framework might know the solution ...

problem solved ...
I reprogrammed it in visual studio 2003 instead of visual studio express 2008

I created C# application that connects to MS Access Database
I compiled, built, and ran the application, and everything went well
Then I copied the *.exe file to another folder and other computers
I ran it many times with no problems
But, sometimes it does not work and displays the message (Unable to find a version of the runtime to run this application)
And this problem is not solved till I rebuild the source code again
I rebuild and run for 10s of times and the problem appears again
What is the source of such aproblem, and what is the true solution

When you are not sure if client computer has necessary all .dll's, runtimes etc. installed, you should make setup project for your application.
In setup project you can deal with prerequisites.
This is highly unlikely, but stranger things happened to me,
do you have some .dll's in your bin directory? Perhaps you forgot to copy them.
Edit: I've read your personal info after I've posted my answer, so please excuse me for patronizing tone; as I've said, stranger things had happened to me and to my local Gandalfs.

First of all, thanks for your reply
I post this qustion along time ago with no response

you will be surprized when you know that this problem occurs with the executable file even while running from the bin directory itself
another thing I recently noticed, is that th file size changes
when it runs proberly its size is 452 kb
when it fails, its size becomes 484 kb

It seems to be really a virus activity, in spite of I scanned my machine and got none infected files
But, I discovered the problem source
The executable file is opened somehow and some bytes are appended making it unusable.
So, the simple solution I did is ....
... I put the file in the READ ONLY access mode
Now, everything works well
Thanks to all participants

Hi everyone!
I want to reduce the numbers of colors in images dynamiclly in asp.net. For that I use this library (Source code). I use the PalettQuantizer class to reduce to specific colors specifyed in an ArrayList. But if I make the palett bigger than 256 entries, I get IndexOutOfBoudsException. I get the exception because the Bitmap.Palette.Entries array just can hold 256 entries. But if I want a palett that is bigger, how should I do?
Regards Tobias

Microsoft are retiring the MCAD/MCSD March next year. I remember a poll on here about which version of the .NET framework developers are targeting. The majority said 2.0.
I have an MCAD and wish to upgrade it to a higher qualification, and I feel that going for an MCSD would be a bit of a wasted effort as it targets 1.1 and will soon be obsolete. Many jobs I have seen require experience with 2.0 or higher.
If I go with the MCSD, I fear that version 4.0 of the .NET framework will come out by the time I've done it. So I'm thinking I will upgrade to an MCPD to catch up a bit. Any thoughts on this?

I would say go for the upgrade to MCPD, especially since the MSCD is also being retired.

What's the upper limit on the number of projects for solution in VS2005 ?
|
|
|
|
|
Not sure if there is any. Hard disk, available ram, and processor power, human sanity dealing with a slow load, are probably the deciding factors on the limits. Have you seriously tried googling around? Maybe MS has the actual number somewheres in their docs?

After a quick google around, nothing much. Probably depends on your hardware, number of developers, resources available.

Hi all,
I am developing an application that plots the timeseries data.
Currently, I have used SQL Server to store the data and ChartDirector to plot the chart.
But the application is slow and takes long time (40-50 seconds) just to plot 1 million data points. What I do is fire select query to database and use the result to draw that chart using CharDirector.
Please suggest me on how can I improve the speed of this application?
I am thinking on sampling (if data is too huge like fromo 2000 - 2005).
Nevertheless, I should not miss out the outliers meanwhile.
I would be grateful for your help.
Thanking you!

I have code along the lines of:
try
{
MarshalByRefObject obj = (MarshalByRefObject)RemotingServices.Connect(
typeof(MyClasss),
"http://MyServer:8080/MyClass");
MyClass class = (MyClass)obj;
class.CallSomeMethod();
return;
}
catch
{
return;
}
In the above code, if for whatever reason I can't connect to my server, an exception is thrown, I eat it, and move on. That's all expected.
What I'd like to know is: Is it possible to set how long the timeout is before the remote request gives up? If the server is down, it can take a while before the exception is thrown - sometimes a minute, and I'd like to limit it to something low, like 10 seconds.
Thanks,
Jeff

Thanks! I wasn't evening thinking about HttpClientChannel (and I wasn't aware of the configuration dictionary that's passed in), just MarshalByRefObject.
Thanks,

If an object reference were stored adjacent to an integer in the same oct-word, or if two object references were stored likewise, is there any reasonable way to to a single CompareExchange that will update both of neither has changed or leave both alone if either has changed? Many algorithms for non-blocking updates seem to want a 'CompareExchange-plus'. From a hardware perspective there should be no difficulty(*), but since .net needs to "know" about objects, storing two object references in a Long would seem problematical.
The closest approaches I can figure would be to either (1) when it's necessary to have one 'extra bit' with the object reference, create two objects that the object reference can point to, both of which have pointers to each other. One of them is the real object, and one is a spare. If the object reference points directly at the "real" object, the "extra" bit is "zero"; if it points to the spare, it's "one". This avoids any need to create new objects while doing the update; (2) have the object reference point to an intermediate object which holds the real object reference and the other data; to do an update, copy the data from the old intermediate object to a new one and then CompareExchange the reference to the old to point to the new. That approach allows an arbitrary amount of supplemental data, but is more apt to tax the garbage collector. Further, even if the rest of the algorithm is interference-free, the memory allocation isn't.
Anyone have any brilliant insights?
(*) I wouldn't be surprised if object references in IA64 fill up the largest available CompareExchange type, but I can't see any real reason they should. If an object reference stores an index into a system-maintained array of objects, then 32 bits should be plenty for that purpose. I don't want to sound like Bill Gates' "640K is enough for everyone", but I can't see much use for having four billion live objects. If an application would need anything near that number, I would think it would be more efficient to use fewer objects and store more information in each.

32-bit processors support 32-bit interlocked operations; 64-bit processors in 64-bit mode support 64-bit interlocked operations and that's it.
Lock-free programming is very, very hard and requires you to fully understand the memory model. It's much easier to use actual locks until you can prove that the lock is the bottleneck. I suggest you read Herb Sutter's DDJ article Use Critical Sections (Preferably Locks) to Eliminate Races[^].
The .NET Monitor is a very low cost lock: it spins on a condition variable for a while, before eventually waiting on a Windows event object (allocating one if there wasn't one). This is much the same as the Windows CRITICAL_SECTION structure, if initialized with the InitializeCriticalSectionAndSpinCount function.
