Thanks a lot to all.
I got it. One clarification.
string[] weekdays = { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };
...
string day = weekdays[3];
If I use this method, is it creating a RAM string array? or is this array in ROM only? unlike a variable string?
I am using enum .
Thanks a lot

Depends on your compiler. For Visual Studio, it will always be a RAM string, because it won't let you prefix it with "const" because it is a reference type and it (understandably) won't let you initialize const reference types other than string. Despite it being an array of strings. Grrr.

on a PC the file system probably resides on a disk, and anything you load from disk is located in RAM; the only thing in ROM (or EEPROM) probably is the BIOS code.
However literal strings belong in code space, not data space. Code space could be write-protected at run-time.

Hi,
i have a question about the DataGrid and the DataGridBoolColumn.
Is it possible to disable a CheckBox shown in the DataGridBoolColumn? I get a result of a Database Query. If the Value is true or false the CheckBox should be enabled and the CheckBox is checked correctly, but if the value is NULL the CheckBox ist disabled and checked, i want to get a unchecked and disabled CheckBox in that case.
Thanks for your help!

I am creating a web service project in C#. It has a file containing classes, used by the web service.
Problem 1. When I type a local variable inside the class, it is not showing intellisense. for example I am typing the code for class B, which has local variable for class A. When I am going to type objA (object for the class A) and then DOT (.), class A's members are not displayed.
Problem 2. Inside the web method, if i make typing mistake; i.e. wrong variable name or missing semi colon at the end; still compilation goes successful, while I see, there are errors.
Anybody has experienced this? I am facing this problem 1st time and feel much difficult to continue coding. Please point me to right direction.
Thank you for your help in advance

hi,
problem1: if your local variable is private you cannot access the var from classB by typing new classA().var .. create a property or declare the variable as public. (i guess that could be a problem).
problem2: you might check whether the class you want to compile has the buildsettings compile or some else..
hope i could help

Thanks for ur reply but it seems u didnt understand my question or may b i could not explain properly. Local variable means variable for instance of class A.
<br />
public class B<br />
{<br />
private A objA;
}<br />

Hi,
make sure the following option is set, using menu Tools/Options/ProjectsAndSolutions/BuildAndRun:
"On Run, when build or deployment errors occur" = "Do not launch"

Dear Luc Pattyn
Thanks for your reply. I tried that but it didnt solve my problem. I am also observing other behaviors also such as , when I right click on any class, I cant see "View class diagram" menu. Hence I cant create diagram.
This only happens in this project while in same Solution, other project is there, which is not mentioning this problem.

I solved my problem.
I opened the project file in text editor. I noticed that my all classes in App_code were not added in compile tag, hence compiler was not compiling those classes. That is why errors were not detected and classes were not added in final assembly file (dll). This was the reason class objects were not showing intellisense.
I added manually my classes in compile tag and everything is working fine. Still could not know why those classes were not added in project file (.proj) for compilation.

Unfortunately the only part of that message that visual studio gives you access to is the Product name.
If you want more control over the installation experience you will have to use a different installer technology such as WIX[^]. I believe WIX projects can now be integrated into Visual Studio via a Visual Studio Addin, though I prefer the integration you get in Sharp Develop which uses WIX as it's default Installer project engine.
If you have knowledge, let others light their candles at it.

They WERE working TOMORROW ?
Perhaps if you posted some code ? What has changed since 'tomorrow' ? Something must have changed if it worked before and now doesn't. Have you confirmed your datasource is working ?

when i use the multi-thread i have met a problem just like it:
Object obj;
Thread[] mythread = new Thread[dt.Rows.Count];
for (int i=start;i<end;i++)
{
.....................
if (isSameNet == true)
{
//Begin the thread
mythread[i] = new Thread(new ParameterizedThreadStart(gatherOnlineTimeOfSame)); }
else
{
mythread[i] = new Thread(new ParameterizedThreadStart(gatherOnlineTimeOfDiff));
}
mythread[i].Start(obj);
}
...........................
finally
{
DBer.closeConnection(conn);
}
the code is right when it excute by unuse thread.
but when it excute just as up.the programe will excute,but
the result is wrong.during the programe running it will not has
any error.when i debug it,it will stop on the code "DBer.closeConnection(conn);". By the way the function "gatherOnlineTimeOfSame" and "gatherOnlineTimeOfDiff" are both right, i have tested.
their content are about the DB's operation.
Any help will be appreciated!

I cant make sense of your question. Are you saying that restarting an old thread causes the issue ? Do you have locking code around all your database code ? Do you use transactions to avoid race conditions ?
I assume that start is always 0 and end is always dt.Rows.Count ?

thank you Graus.My problem have been solved.
the reason is that sub thread is running too slower
but the main thread is too fast,the sub thread is deal with DB
so the sub thread is excuting but the DB Connection has been closed.
so the problem ..... Now i updated the source it works OK.
Thank you for your help.

"it works" is a necessary condition, not a sufficient one, for a program to be correct.
If your main thread is to close the database, it has to wait for all other threads to finish.
There are a couple of ways to do this, Thread.Join is one of them.
FWIW: Thread.Sleep is not.

hw can i get the text of node on clicking in treeview?
|
|

I would expect that there's a selection changed event, a selectedItem property, and a Text property on the Node that is the selected item. Is this not so ?

Hey all, i have a question. I've searched everywhere for the answer and I can't find anything. So here it is. This is a part of the code, which I've copied from somewhere by the way.
<br />
public static bool IsUserPlayingFullscreen()<br />
{<br />
IntPtr hWnd = GetForegroundWindow();<br />
if (hWnd == GetDesktopWindow())<br />
{<br />
Logger.LogMessageToFile("F***");<br />
return false;<br />
}<br />
<br />
RECT rcWindow;<br />
GetWindowRect(hWnd, out rcWindow);<br />
IntPtr hm = MonitorFromRect(ref rcWindow, MONITOR_DEFAULTTONULL);<br />
if (hm == IntPtr.Zero) return false;<br />
MONITORINFO mi = new MONITORINFO();<br />
mi.cbSize = Marshal.SizeOf(typeof(MONITORINFO));<br />
GetMonitorInfo(hm, ref mi);<br />
return EqualRect(ref rcWindow, ref mi.rcMonitor);<br />
}<br />
Anyway, here I'm trying to detect if a full screen application is running. Runs pretty nice in most of the situations, besides one. If the desktop window is active, it is tricked in believing it is a FS App. I thought that this
"if (hWnd == GetDesktopWindow())" would detect if the current active window is the desktop, but it doesn't! Any help? Thanx in advance!
