Hi,
I have a DataGrid bound to a DataTable. I used the following code to bind the DataTable,
//
//Set the datasource of the Grid
//
this.dataGridPCUD.DataSource = this.dataTable;
There is a save button that user clicks to save the information. The problem is that when the user
makes changes and clicks Save, the information from the last cell of the GRID is not seen by the
DataTable.
I used the following code to get the changes
CurrencyManager currencyManager = (CurrencyManager) this.dataGridPCUD.BindingContext[this.dataTable];
if (currencyManager != null)
{
currencyManager.EndCurrentEdit();
currencyManager. Refresh();
}
DataTable subDataTable = this.dataTable.GetChanges(DataRowState.Modified);
The heilighted line returns null. But when I check the new value in the DataTable, I see the modifies value.
Everything works fine if the uses tabs out before saving.
Please advise.
Thanks and Regards,
Alomgir Miah

Hi All
I want to show the XML file nodes in a tree view for selection, and then the selected nodes to write in another XML file.
Please Guid me if any one know these things.

Hi,
Please use XmlReader to read the Tree and Load it into Tree recursively.
XmlWriter will do the job of writing.
Here is the code Snippet
void LoadTree()
{
while (xmlTextReader.Read())
{
switch (xmlTextReader.NodeType)
{
case XmlNodeType.Element:
tempTreeNode = new TreeNode( xmlTextReader.Value.Trim());
break;
case XmlNodeType.Text:
Console.Write(xmlTextReader.Value);
break;
case XmlNodeType.CDATA:
Console.Write(xmlTextReader.Value);
break;
case XmlNodeType.ProcessingInstruction:
Console.Write("");
break;
case XmlNodeType.Comment:
Console.Write("");
break;
case XmlNodeType.Document:
Console.Write("");
break;
case XmlNodeType.Whitespace:
Console.Write(xmlTextReader.Value);
break;
case XmlNodeType.SignificantWhitespace:
Console.Write(xmlTextReader.Value);
break;
case XmlNodeType.EndElement:
if ( currentTreeNode != null )
{
if ( currentTreeNode.Parent == null )
{
currentTreeNode = null;
}
else
{
currentTreeNode = currentTreeNode.Parent;
}
}
break;
}
}
xmlTextReader.Close();
}
}
This code is not complete but will give you the idea.
Hope this helps,
Alomgir Miah

I need a function that return int random number:
int myn = RandomFunction(100);
it could generate number between 0 and 99.
Does it exist?

Gee, you must've searched really hard 
Random[^]

look at the Random class in the .net framewok.

Gotta look great in email notification! (or is it only my lame english? I read it like he should randomly pick one of .NET classes...)

I don't get this message either (alluding to the other message of yours in the lounge I misinterpreted).

That's my usual problem. 
When he gets message notification in email, it's without <code> formating, I belive. So when you don't pay attention to case, you end up reading "look at the random class in the .net framewok.". Ohh hey! I think I get it! "look at the random class in the .net framewok." vs. "look at brandom class in the .net framewok." makes the difference, right?  Ok so I would think that you are saying to pick *random* .NET class.

Remember to add a reference to the acme assembly, simply a using statement is not enough.

Hi,
I'm trying to activate a process on a remote machine and doing so successfuly. The only problem is that I' havn't figured out how to know when the process has ended.
here is an example of the code:
private void run_notepad(string machina)
> {
> ManagementOperationObserver observer = new
> ManagementOperationObserver();
> completionHandler.MyHandler completionHandlerObj = new
> completionHandler.MyHandler();
> observer.ObjectReady += new
> ObjectReadyEventHandler(completionHandlerObj.Done);
>
> string stringMachineName;
> string stringCommandLine;
> stringCommandLine="c:\\winnt\\notepad.exe";
> //Connect to the remote computer
> ConnectionOptions co = new ConnectionOptions();
> stringMachineName = machina;
> //get user and password
> if (machina!="")
> {
> co.Username = "aaa";
> co.Password = "******";
> }
> //Point to machine
> System.Management.ManagementScope ms = new
> System.Management.ManagementScope("\\\\" + stringMachineName +
> "\\root\\cimv2", co);
> //get process path
> ManagementPath path = new ManagementPath( "Win32_Process");
> //Get the object on which the method will be invoked
> ManagementClass processClass = new ManagementClass(ms,path,null);
> //Create an array containing all arguments for the method
> object[] methodArgs = {stringCommandLine, null, null, 0};
> //Execute the method
> processClass.InvokeMethod (observer, "Create", methodArgs);

anybody knows how to tell when the process exited?
Thanks,
Haim.

Hi
How can I select a treenode (in coding) on a treeview and keep it selected (High Lighted)?
I tried the following and it doesn't seem to work as required:
foreach ( TreeNode tn in treeView1.Nodes )
{
if ( tn.Text == "Color" )
{
treeView1.SelectedNode = tn
break;
}
}
|
|
|
|
|
Why isn't it "working as expected"?
That's how you select a node, no need to perform different or additional voodoo.
Could it be that your TreeView hasn't got focus and HideSelection is set to true?
Or that there _is_ no node with Text "Color"?

Ok must be that the treeview hasn't got focus...
Thanks

Hi all,
I have a ToolBar on my form. Each button associated to an image from an ImageList.
Why when I disable the button, the button becomes all gray ( and not grayscale image ) ?
Do I have to apply a second grayscale image for each button for disable mode ?
If so, How do I do it ?

here is my problem.
i have a RichTexBox with a document in it. after some modifications it needs to be printed. however in the printed version no white spaces must be left from the end of a paragraph to the end of the line.
i have tried to adjust the size of the RichTextBox to the size of the paper used by the printer (usualy A4) and set left and right indentation of text (making a copy of the rtf before this in order to print it unindented, otherwise it will just double the indentation) accordingly to printer settings indentation values.
however print preview and printed version text differs from the one shown on screen. the text is printed as formated text with justified align and different fonts and sizes, using a control derived from RichTextBox witch has such printing support described here
now if anyone has any ideas as to how i can atleast hadle this problem ..

hi,
i found something rather odd and was simply wondering if anyone can explain this. I have a thread responsible for displaying a Form (in an event driven manner). When trying to display this form, i've notived that usage of .Show() causes the new form to hang (the frame is displayed, but the text field in it is empty, and the mouse shows an hourglass when hovered over this form). On the other hand, use of .ShowDialog() seems to display it fine. Given that it's displayed in its own thread, it doesn't matter which method i use, as the application continues fine. But i was just wondering if anyone can explain why the behaviour is different in this context?
In case it's of any relevance, here's the code
(running on XP Pro, developed in VS .Net 2003 against SDK 1.1)
<code>
public PopupFactory()
{
Thread t = new Thread(new ThreadStart(waitForEvents));
t.start();
}
private void waitForEvents()
{
while ( true )
{
lock(al)
{
Monitor.Wait(al);
l.log("got a pulse from another thread on al");
string[] z_details = (string[])al[al.Count - 1];
ZTransparentWindow z = new ZTransparentWindow(z_details[0], z_details[1]);
z.ShowDialog();
z.Show();
}
}
}
</code>
thanks!

The reason Show doesn't work is because your thread doesn't have a message pump. Without a message pump, your window can't respond to user actions. ShowDialog runs its own message pump on the calling thread, so it works. See this[^] article to know more about message pumps and stuff.

Senthil

I too have come across this seemingly odd error, however the solution is pretty clear once you figure out what's happening. An example solution would be as follows:
private delegate void ShowFormDelegate(string[] details);
...
public PopupFactory()
{
Thread t = new Thread(new ThreadStart(waitForEvents));
t.start();
}
private void waitForEvents()
{
while ( true )
{
lock(al)
{
Monitor.Wait(al);
l.log("got a pulse from another thread on al");
string[] z_details = (string[])al[al.Count - 1];
this.ShowForm(z_details);
}
}
}
public void ShowForm(string[] z_details) {
if(this.InvokeRequired)
{
this.BeginInvoke(new ShowFormDelegate(ShowForm), new object[] z_details});
}
else
{
ZTransparentWindow z = new ZTransparentWindow(z_details[0], z_details[1]);
z.Show();
}
}
Although I haven't tested the code, and therefore cannot guarantee that it works, you should be able to get the idea behind it. I myself am still not QUITE certain why the Show() method doesn't work the way you had it, but I assume it has something to do with the thread that it's being called from. This method guarantees that the form is spawned from the main window. Good luck.
