You can, of course, post other questions here, or in the QA forums.
Keep in mind that for any TreeNode you have several possible 'dynamic visual state' factors that may determine your choice of images to be used in displaying the node:
1. has child nodes, or has no child nodes
2. if has child nodes: is expanded, or collapsed
3. is selected, or is not selected: unfortunately unless you owner-draw the TreeView you have no control over the selection highlight color, and every scheme I have seen to work-around this (using the TreeView as is: i.e., not owner-drawn) has been not useful (impaired performance, etc.).
4. the current level: this could be a dynamic factor if you are implementing drag-drop in the TreeView
To assist you in determining the node's current state at run-time there are four boolean properties which are read-only:
IsEditing
IsExpanded
IsSelected
IsVisible

..'tis was downvoted, but I cannot think of any valid reason why. So, I upvoted it.
If anyone thinks this is NOT a good way to answer, please do explain it to me, using small short* sentences and simple words.

Hi,
I am using the following to loop through date range and import into a database from text files. I want to know how can I tell the code IF FILE DOES NOT EXITS THEN CONTINUE TO NEXT FILE?
for (DateTime date = last_date; date.Date <= DateTime.Today; date = date.AddDays(1))
{
string file_name = "H" + date.ToString("yyyy-MM-dd") + ".TXT";
MySqlBulkLoader bl = new MySqlBulkLoader(sql_connection);
bl.TableName = "processing_table";
bl.FieldTerminator = ",";
bl.LineTerminator = "\n";
bl.FileName = @"C:\Temp\Attendence\" + file_name;
bl.NumberOfLinesToSkip = 0;
int count = bl.Load();
string sql = "SELECT source, created_date, created_time, company, action, employee_number, employee_name, outlet, field_1, field_2, field_3, field_4 FROM processing_table";
MySqlCommand cmd = new MySqlCommand(sql, sql_connection);
MySqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
SplashScreenManager.Default.SetWaitFormDescription(rdr[1] + " - " + rdr[2]);
}
rdr.Close();
}

I´m not sure where it´s failing, but try creating a FileInfo object (System.IO.FileInfo) that object has an exists method that will return true/false if a file exists.

Aight, I'd accept it if you posted it once, but it the URL is NOT a valid question to "all" answers.

Something similar to this should be what you're looking for.

What's your question?
There are only 10 types of people in the world, those who understand binary and those who don't.

Code is string filepath = @"C:\\"+"k.xls";
string sheetName = "general_report";
var excelFile = new LinqToExcel.ExcelQueryFactory(filepath);
excelFile.DatabaseEngine = DatabaseEngine.Ace;

Use either @ (verbatim string) or escape the backslash, not both. And why concatenate?
string filepath = @"C:\k.xls";
ought to do it.

Only works if the entire process is 64-bit.
"Didn't work out", what does that mean? Did it throw an exception, did it explode?

Hello. I have started a process using Process.Start. Now when I resize my panel, I also resize this control. But the problem is, it stops resizing after I drag its border just a little bit. It does, though, resize for that little bit drag of form border. So question is why can not I resize my external program along with panel, just like I resize my panel along with form? Thanks for any pointer.
UPDATE
I have a process that I have started using Process.Start() and placed it on the panel, on my form. Now in order to resize it, I put this code
private void Form1_SizeChanged(object sender, EventArgs e)
{
SetWindowPos(m_hHandle, 0, 0, 0, panel1.Width, panel1.Height, SWP_SHOWWINDOW);
}
I put a breakpoint on this function and noticed that as soon as I resize my form, this breakpoint gets hit. How do I resize this control on my form using Resize or SizeChanged events?

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Edit your question and provide better information.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

I note you use the word 'Control to describe what you are working with, but using Process.Start runs an Application that then puts up a window(s).
1. what is the Application you start using Process.Start ?
2. what are you doing to make that Application's Window(s) a child Control of the Panel (added to the Panel's ControlCollection) ? or, is it (more likely), that the application window is not a child of the Panel ?
3. is it possible that whatever application you start's window has a fixed window size maximum ?
4. if you make the Panel size smaller: what happens to the hosted whatever ?
More specific details, please.

1 - I am hosting media player classic. I start this application using Process.Start.
2 - Don't know what to say.
3 - NO
4 - nothing

I'd be interested in the answer to 2. Dark magic, perhaps.

Hi Rob, My understanding is that some applications are designed to be "embeddable" ... like Mozilla, IE. In this case we don't know what app the OP wants to launch, or even if he needs it to be "embedded."
cheers, Bill

Interesting. I'll have a look at that later on.
My thinking is its a protected operating system so the idea of borrowing a windows handle from one process and incorporating into the hierarchy in another would be strictly unavailable.
But, as one other comment points out, what about OLE?. More thought/research required.
[Edit] - even if possible somehow, it sounds like a dreadful idea.
Regards,
Rob Philpott.

That is a bit confusing, does it resize or does it not? Is this window a child of your panel (i.e. how are you hosting it) or are you just positioning it above your panel?

Please read my updated question. As I said there, breakpoint gets hit which means that I can not go on and continue resizing my form.
