yes i do know that Nested class name cannot be as same as its holding class, but when i tried to Decompile a DLL it show similar kind of code inside that,
Any idea on that
|
|
|
|

A nested class can contain anything, methods, fields, properties, events, etc.
I think I do not understand what you are having a problem with.
Can you try explaining what you are trying to do or having a problem with in more detail, please?If Barbie is so popular, why do you have to buy her friends?

When I publish my C# application using Visual Studio Express, and install it, it creates a ClickOnce Application Reference file on the desktop and in the Start Menu instead of just a normal .EXE file - and this is screwing up my File Associations. Could someone kindly suggest how I could have txt files etc opened in my application when dealing with Application Reference files?
Thank you
|
|
|
|
|
The real .exe file will be stored somewhere in the user's AppData folder (I think).
Why not have the associations set on first startup of the program? You could have your software enter the details in to the registry (note: potential permissions/UAC problem) as it will know exactly where it is.
|
|
|
|

Thank you - I have searched my entire hard drive in every possible place that there would be an executable file but have not found any. I even checked the AppData folder. Nothing at all. Just a bunch of ClickOnce Application Reference icons.
I also tried setting registry info for the associations on startup and it has been unsuccessful. I don't get any errors at all... It just doesn't work.
I've also (originally) tried using the File Association dialog that's inside the Publish page where you publish the project and entered ProgID info and icons etc and that approach hasn't worked either. But, funny thing... The custom Icons I used in the File Association dialog in VS are showing up on the files... My app just isn't loading the content of the files that are being double-clicked.

I have the following code:
using System;
using System.IO;
using System.Xml;
public class Sample {
public static void Main() {
string strQuery;
XmlDocument doc = new XmlDocument();
doc.Load("booksort.xml");
XmlNode book;
XmlNode root = doc.DocumentElement;
book=root.SelectSingleNode(strQuery);
}
}
In the call to SelectSingleNode, how do i formulate my strQuery so that I get the FileValue2 (in this case it is 'swethrhbfb') where FileValue1="00000002.dat"
Many thanks!

Hi all, i need helping about
<code>if (pcap_addr.Addr != IntPtr.Zero)</</code>
is that mean (at C++):
<code>if (pcap_addr.Addr != null)</code>
|
|
|
|
|
MSDN[^] says "The value of this field is not equivalent to a null reference"
So, not quite, but similar.If Barbie is so popular, why do you have to buy her friends?
Eagles may soar, but weasels don't get sucked into jet engines.

I would read the first as there is/was "something", but it is not valid.
The second is more like, there is "nothing" or "not applicable", not applicable is even more correct I think.V.

|

Hi all, i read that but don't understand it, can you illustrate it to me, pleae,,.
<pre>[SuppressUnmanagedCodeSecurityAttribute]</pre>
// Allows managed code to call into unmanaged code without a stack walk.
// 1- This attribute can be applied to methods that want to call into native
// code without incurring the performance loss of a run-time security check when doing so.
// 2- Using this attribute in a class applies it to all contained methods.
regards..,
|
|
|
|

This just basically means what it says:
Increase performance when using pInvoke, but make sure to deal with the security issues that follows.
Every method in a class decorated with this attribute also gets the attribute.

helo,
i want to create a process,that if i click log-off to my user is still running and working.
how i do it?services?system process?Special process?
I would be happy to detail some.

| Windows Service would be the way to go, set to 'automatic' to get it to start when the computer does, and probably using the local system account. Regards,
Rob Philpott.
|
|
|
|
|
Yes, a Windows (NT) Service is the way to go here. There are plenty of articles on how to create one so google will provide you with many of relevant answers on this matter. Good luck! 
|
|
|

A Windows Scheduled Task might do it as well.

Hi,
I would like to use Multi threading to improve the performance. I have a datatable it may have any no of records. But the problems is i have to split those records and assign some records to one thread, some other records to other thread and so on.
I will pass the table,no of threads, records for thread like the following
public void MultiThreadingSample(DataTable table, int noOfThreads,int recordsForThread)
{
}
please help to me.

Hi Guys. I have a slight problem. I have written an app that processes various types of files. I create a Thread for each type of file being processed depending on a checkbox being checked.
Now, from each file processed I output totals to a label on the form. However, this only seems to work for the first two files being processed and the remainder does not get their totals output to the labels. Is this a known issue and is there a way I can get around this? The code is kinda long so don't really want to add any here now. But the process flow of the program is such.
1) User selects a searches for file to process.
2) User checks the appropriate checkbox.
3) Thread is started calling the block of code to run.
4) Once file is processed finalize by calling GC.Collect().
if user wants to process another file he unchecks the current chechbox, checks a new checkbox and searches for new file and above process is followed calling the appropriate Thread to run.
Can somebody advise why when running more than two "Thread" processes in succession results in the third and fourth not outputting totals to the Label's?Excellence is doing ordinary things extraordinarily well.
|
|
|
|
|
Without some idea of the code it is really difficult to suggest anything, but there general things you can check:
Are the thread running at all? Add some logging to a file to record what is being done, and in what order.
Are the output overwriting each other? Try logging the outputs as well.
Are the thread having problems with conflicts? Are there any locks which might be waiting?
Is it always the same threads that don't run? Or does that change depending on what order they are started in, say?
Sorry not to give concrete answers, but there is a heck of a lot that could be going wrong here - I think your first call is to gather more info!If Barbie is so popular, why do you have to buy her friends?

Without actually running it, I can't see anything obviously wrong.
Since this is the code that (doesn't) show the problem, I would be tempted to try
private void setFilename(Control lblctrl, string filename)
{
Console.WriteLine("setFileName Entered: " + lblCtrl.Name + " : " + filename);
if (this.WindowState == FormWindowState.Minimized)
return;
Console.WriteLine("setFileName PreInvokeCheck: " + lblCtrl.Name + " : " + filename);
if (lblctrl.InvokeRequired)
{
Console.WriteLine("setFileName BeginInvoke: " + lblCtrl.Name + " : " + filename);
lblctrl.BeginInvoke(new SetLabel(setFilename), new object[] { lblctrl, filename });
}
else
{
Console.WriteLine("setFileName Direct: " + lblCtrl.Name + " : " + filename);
lblctrl.Text = filename;
}
}
Or equivilent to check if it gets to the "setFileName Direct" bit when you don't get the label written. It may give a clue to what is going on (or worse, remove the problem)If Barbie is so popular, why do you have to buy her friends?
Eagles may soar, but weasels don't get sucked into jet engines.

you are not supposed to touch a Control from a thread that did not create the Control. While your code is using several InvokeRequired/Invoke patterns, it is also not using them in several locations, see:
1.
if (this.WindowState == FormWindowState.Minimized)
is probably OK, but not documented to be OK
2.
infile = txtboxSelectFile.Text;
is probably not OK (not documented, I guess it is not OK for Controls that allow text editing)
3.
outfile = saveFileDialog1.FileName;
is most likely not OK, file dialogs are known to be critical (e.g. you need STAThread for them)
IMO you should fix all of the above.

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that. All Toronto weekends should be extremely wet until we get it automated in regular forums, not just QA.

Hi Guys,
I'm trying to do something that looks easy but for some reason doesn't work.
I have a window service which loads .dll's that are in a different directory every couple of minutes.
I need to update those .dll's every now an than so I created an AppDomin and from there I want to load the .dll's in to the main AppDomain.
The strange thing is when I try to load a .dll I get an exception that the .dll can't be found.
Here's the source code:
AppDomainSetup AppDomSetup = new AppDomainSetup();
AppDomSetup.ApplicationName = "Service Name";
AppDomSetup.ApplicationBase = Application.StartupPath;
AppDomSetup.PrivateBinPath = "alerts";
AppDomSetup.ShadowCopyFiles = "true";
AppDomSetup.CachePath = Path.Combine(Application.StartupPath, "_cache");
m_FilesDomain = AppDomain.CreateDomain("Ksm Scheduler", null , AppDomSetup);
m_FilesDomain.Load("alert1.dll");
The 'PrivateBinPath' property points to the directory that contains the .dll's.
The 'cache path' folder IS CREATED but I get an exception. When I place the .dll's in the 'ApplicationBase' directory i.e. in the directory of the .exe file, the .dll is loaded.
Thanks for any help,
Avi

Don't have an answer to your immediate questions, but a couple of queries. Firstly, are all these DLLs .NET assemblies? Are you using shadowing so you don't lock the file in question so it can be altered elsewhere? When a dll is changed, do you want to unload the last one and replace it with the new one?
The bit which sounds really odd is loading the dll into the main application domain (which you can't unload). Do you not want to create a new domain, load the dlls in there and then unload it when they need to be updated?Regards,
Rob Philpott.

Hi Rob,

Yes, all the DLL's .NET assemblies.

Yes I'm.
3. Rob Philpott wrote: When a dll is changed, do you want to unload the last one and replace it with the new one?
Yes, exactly.

I DO want to create a NEW domain, which I did, but for some reason the .dll aren't loaded into it. Besides, Although I don't understand how the .dll file, after is was updated, gets updated also in the new doamin without me unloading it i.e. I don't want to unload the .dll when it's changed. That is the whole purpose of shdowing, right? ( or wrong?)
One more important thing.
If I place the .dll's inside the ApplicationBase directory, the .dll's ARE loaded. When I create the new domain I give it a AppDomainSetup object with all the details. I assign to the PrivateBinPath the folder which the .dll's reside ( the folder is inside the main application folder, of course)
