Hi All
I’m trying to make a list view to catch multithreads. I have a tree view on the right and the list view at the bottom. i want to find out how to display what has been open in the MDI. E.g. if I open a form called email using the treeview I it should display the details that I opened the email form in the list view. It is something like Microsoft Dynamics SL -Solomon
I am very new at c#

Do you mean you do something on the form (or the TreeView), and then some backend processing happens in a thread and when the results come the ListView gets updated? If so, use BackgroundWorker helper class in the System.ComponentModel namespace.

I want to get RTC(Real time clock) time in c#.
How can i do that? Thank for your answer. 
|
|

I think System.DateTime.Now is OS time not RTC time.
|

Where do you think the OS gets it's time from?
The RTC is a bit of hardware that keeps track of the time while the PC is powered off. When the PC is powered on again, the time in the RTC is loaded and used by the OS.
Depending on the OS, it may then rely on the RTC to count the time, and make a call to the hardware when over the time is needed, or it may keep track of the time using itself a software clock/counter.
Either way, the value you get returned to you is the current time as far as the system as a whole is concerned. There is no need to distinguish between "OS time" and "RTC time" one is simply used to back the other.
Unless you have a very strange and unusual requirement where you must have the actual hardware RTC value, just use DateTime.Now.

I have the follwing Problem. We have developed an application for a mobile device using windows mobile 5 as operating system. In the next step we want to install new versions of the software but we neet to uninstall the old version first. Since we don't have Active Sync all the time, and we don't want the user to uninstall the software over the systems>remove programs.
I'm just looking for the exe which is capable of removing applications from the mobile device, similar to msiexec.exe on other windows based systems. And then using c# code to remove/uninstall the application.
Any ideas?

Hi..
I need to get the List of all the user Name from Active Directory, i used the following code.
try{
ADEntry = new DirectoryEntry("LDAP://" + Session["DominName"].ToString() + ".net", txtUserName.Text.ToString(),
txtPassword.Text.ToString(), AuthenticationTypes.Secure);
nativeObject = ADEntry.NativeObject;
}
catch (Exception)
{
DirectorySearcher mySearcher = null;
mySearcher = new DirectorySearcher(ADEntry);
mySearcher.SearchRoot = ADEntry;
mySearcher.Filter = "(&(objectClass=USER))";
mySearcher.SearchScope = SearchScope.Subtree;
mySearcher.PropertiesToLoad.Add("SAMACCOUNTNAME");
mySearcher.PropertiesToLoad.Add("cn");
mySearcher.PropertiesToLoad.Add("mail");
SearchResult srh = null;
srh = mySearcher.FindOne();
int intSerialNo = 1;
foreach (SearchResult resEnt in mySearcher.FindAll())
{
resEnt.Properties["SAMACCOUNTNAME"][0].ToString();
resEnt.Properties["cn"][0].ToString();
resEnt.Properties["mail"][0].ToString();
}
But it is listing Max 1000 users details but there are 2000 entries in the ADS under "user" group..<br />
<br />
<br />
Please anyone Help me to get the list of all the 2000 user's list in ADS..<br />
<br />
if there is a limitation for LDAP protocol.. Can any one suggest other protocol, i tried with WINNT, NDS and IIS also..<br />
<br />
<br />

Yes, LDAP has a limit of 1000 result for a single search. To avoid that you must perform a paged search.
To do that, just set the PageSize property of the DirectorySearcher object to a value greater than 0 (e.g. 500 or 750) before calling the FindAll method.
The MSDN documentation for that is Here[^].

Hi friends,
I have a RichTextBox control, and read a part of a file into a MemoryStream and then load that in my RichTextBox, here's my code:
void FillRTB(string filepath)
{
MemoryStream memStream = new MemoryStream();
FileStream fs = new FileStream(filepath, FileMode.Open, FileAccess.ReadWrite);
byte[] ByteRead = new byte[1];
for(int i = 0; i < 300; i++)
{
fs.Seek(i, SeekOrigin.Begin);
fs.Read(ByteRead, 0, 1);
memStream.WriteByte(ByteRead[0]);
}
rtbText.LoadFile(memStream, RichTextBoxStreamType.PlainText);
}
But rtbText shows nothing! I have no error too!
Any idea? Thank you.
While (true) { Human.isLearnable = true; }

How about this?
void FillRTB(string filepath){
byte[] ByteRead = new byte[300];
using (FileStream fs = new FileStream(filepath, FileMode.Open, FileAccess.ReadWrite))
{
fs.Read(ByteRead, 0, 300);
}
MemoryStream memStream = new MemoryStream(ByteRead);
richTextBox1.LoadFile(memStream, RichTextBoxStreamType.PlainText);
}

Well, I had error, "The name 'fs' does not exist in the current context"
I tried this:
void FillRTB(string filepath)
{
byte[] ByteRead = new byte[300];
FileStream fs = new FileStream(filepath, FileMode.Open, FileAccess.ReadWrite);
fs.Read(ByteRead, 0, 300);
MemoryStream memStream = new MemoryStream(ByteRead);
rtbPage.LoadFile(fs, RichTextBoxStreamType.PlainText);
}
and yes, it works, Thanks. But what if I have a dynamic length? Ex:
void FillRTB(string filepath, long Characters);
While (true) { Human.isLearnable = true; }

Sorry about that. It is fixed.

Unless you don't know how much to read, how can you do it? You have to pass length to FillRTB method.
|
|
|
|
|
Can I dynamically get the length?
void FillRTB(string filepath, long length);
While (true) { Human.isLearnable = true; }

I didn't get you. What do you mean by dynamically getting the length?
|
|
|
|

Sorry, My Bad English... 
I mean how can I implement this:
void FillRTB(string filepath, long length);
I mean how can I have a variable with dynamic length?
Sorry again
While (true) { Human.isLearnable = true; }

void FillRTB(string filepath,long length)
{
byte[] ByteRead = new byte[length];
using (FileStream fs = new FileStream(filepath, FileMode.Open, FileAccess.ReadWrite)) {
fs.Read(ByteRead, 0, ByteRead.Length);
}
MemoryStream memStream = new MemoryStream(ByteRead);
richTextBox1.LoadFile(memStream, RichTextBoxStreamType.PlainText);
}

Thank you very much. That's work...

I thought we can't declare variables like this. And actually I didn't test that
Thank you again

Hi
We use an external library with a class with a static event looking like this:
public static event EventHandler ThemeChanged .
I want to clear it's invocation list, is that possible?
Anything that would cause ThemeChanged to not hold references to anything will do
Thanks

Try setting that to NULL.
|
|
|
|
|
Unfortunately it's not that easy
error CS0079: The event 'ThemeChanged' can only appear on the left hand side of += or -=.
It would also be easy using reflection if it was non static.
|
|
|
|
|
Ok, how about writing a method which sets this to NULL?
class MyTheme
{
public static event EventHandler ThemeChanged;
public void ClearInvocationList()
{
ThemeChanged = null;
}
}You can implement this in destructor and use dispose pattern and set it to NULL.
