Would not be like range from -1000 to 1000?
With step of 1? That would be 2001 values not 100? Am i missing something?

Here's a little trick for you - open up Calc.exe and type in 10000-20000. See what answer you get.
|
|
|
|
|
Equal -10000.
what is you point? I'm not getting it?
|
|
|
|
|
My point is that his calculation is wrong. Ignore it - between 10000 and -10000, there are only 20000 integers, not 20001.

I am not confusing anyone. It depends (forgive me if I am not using proper terminology) of range. Is this closed? Opened? From both or from one side? For example range <-1,1> have 3 integers. Range <-1,1) have 2 ints. (-1,1> have 2 too. But (1,1) have only 0. Your substraction is range (-10000,-10000>. For me in this case you should either take closed from or opened from both range. But question is not clear about that som I can be wrong.

There are some different solutions and you have to decide.
There are 20001 values (in complete range) or having 20000 values (in reduced range -9999 to 10000)
In first case there should be 101 tags (-10000, -9800, ..., -200, 0, +200, ..., +9800, +10000) (same interval, 200)
In second case you could use 100 tags (-9999 to -9800, -9799 to -9600, ..., -199 to 0, 1 to 200, ... 9801 to 10000) (same blocksize, 200).
Otherwise the tags wouldn't have same size and same interval.

Hi, Im using Oracle database and I cant find the solution for SELECT,UPDATE,DELETE,INSERT query to access the ORACLE tables using VARIABLE in C# . .
Im using this Code and it dosnt work? what should I need to do? I think there is something wrong in (cmd.Parameters.Add) when I do assign VARIABLES.
con.Open();
cmd.Connection = con;
cmd.CommandType = CommandType.Text;
cmd.CommandText = "INSERT INTO OUT_TEXT_NORM (KEY,LANG_ID,TEXT, PRIO) VALUES (:key,:lang_id,:text,:prio)";
cmd.Parameters.Add(":key", OracleDbType.Varchar2, 60).Value = key;
cmd.Parameters.Add(":lang_id", OracleDbType.Int32).Value = lang_id;
cmd.Parameters.Add(":text", OracleDbType.Varchar2, 4000).Value = text;
cmd.Parameters.Add(":prio", OracleDbType.Int32).Value = prio;
cmd.ExecuteNonQuery();

Are you getting an error of some type?
Can you explain what does not work.
|
|
|
|
|
It say's Invalid command for CMD
|
|
|
|
|
Try renaming the text-column; it's probably a reserved word.
|
|
|
|
|
Is there any other way in assinging variables?
|
|
|
|
|
Nope.
Still, I don't think the code is faulty; it's more likely to be the Sql command. A column named "TEXT" might be confusing to the parser.

Today the ports were getting confused and Win'7 was lying to me again.
I first removed the device (Control panel ---> Devices and Printers ---> removed the external device which was connected by BlueTooth.)
I then went to device manager, and deleted all the ports that I knew were bogus.
I then went back to Devices and Printers
I added the known device.
Windows reported that COM20 was back on the list.
There were a total of 4 Com Ports
COM1
COM2
COM18
COM20
Within a few minutes, I watched, king of the clueless, as Windows started adding more Com ports, specifically,
COM25
COM28
COM29
COM30
Following this, Win'7 begins lying to me again, telling me that I have two COM20 ports.
This was exactly and precisely the same problem I had which kept me chasing clouds for 10 days, and I do not want to repeat the previous behavior.
There are a total of 4 USB devices connected to this machine
One USB Hub with three devices attached
-- A debugging device for the embedded system
-- An external hard drive
-- The bluetooth device
There is one other USB cable connected to thin air
What on earth is going on ?
Why is Win'7 reporting two COM20 ports ?
I welcome and thank anyone who can provide any answer behind all this.

You need to ask this in the hardware forum. This has nothing at all to do with C#.

Sorry, NewBee NoClue, Mods ? Can you move this ?
Can I ?

I must be slipping. This used to work...
The XML file:
<?xml version="1.0" encoding="utf-8"?>
<Properties>
<PropertyEditor>
<Property ViewName = "Characteristics" PropertyName = "ValueLand" DisplayName = "Land Value" DataType = "numeric"/>
<Property ViewName = "Characteristics" PropertyName = "ValueStructure" DisplayName = "Structure Value" DataType = "numeric"/>
<Property ViewName = "Characteristics" PropertyName = "ValuePersonal" DisplayName = "Personal Value" DataType = "numeric"/>
</PropertyEditor>
</Properties>
and the code to read it
private void GetPropertyData()
{
propertyDatas = new List<PropertyData>();
string path = Path.GetDirectoryName(Application.ExecutablePath) + @"\EditorProperties.xml";
XmlTextReader reader = new XmlTextReader(path);
XmlDocument doc = new XmlDocument();
XmlNode node = doc.ReadNode(reader);
foreach (XmlNode childNode in node.ChildNodes)
{
foreach (XmlAttribute att in childNode.Attributes)
{
PropertyData propertyData = new PropertyData
{
ViewName = att.Attributes["Characteristics"].Value,
PropertyName = att.Attributes["PropertyName"].Value,
DisplayName = att.Attributes["DisplayName"].Value,
DataType = att.Attributes["numeric"].Value
};
propertyDatas.Add(propertyData);
}
}
}
Now, for some reason, it reads the 'XML' line, then the code skips out on the first foreach.
What's wrong here?
Thanks
If it's not broken, fix it until it is

I cannot say whether or not this used to work; but when debugging, it tries to iterate the children of the first element. The first element being the <xml> tag, and it has no children.
XmlTextReader reader = new XmlTextReader(path);
XmlDocument doc = new XmlDocument();
reader.MoveToContent();
XmlNode node = doc.ReadNode(reader);

That's exactly what I said in my post.

In that case, it would have been a duplicate. Did you do any updates? (Software-updates, VS, Automated Updates, MSXML?)
Could it be that your Xml "used" to simply not have the first line in there? In that case, the code would have worked, as is.

Somehow got your attribute names screwed up:
PropertyData propertyData = new PropertyData();
{
propertyData.ViewName = childNode.Attributes["ViewName"].Value;
propertyData.PropertyName = childNode.Attributes["PropertyName"].Value;
propertyData.DisplayName = childNode.Attributes["DisplayName"].Value;
propertyData.DataType = childNode.Attributes["DataType"].Value;
};

I am not sure how to do this and need some help....
I have a couple of functions that are identical other than one input parameter, signatures look like:
public void Func(Dictionary<string, int>)
public void Func(Dictionary<int, int>)
these end up calling the same functions with different signatures, but as I said, do the same thing.
What I want is to combine them both into 1 function that handles both cases.
Can it be done, and if so how?
Thanks!

"What I want is to combine them both into 1 function that handles both cases. Can it be done, and if so how?"
Implement the string version, then convert the ints into strings to use it with ints.

Maybe. But C# generics aren't C++ templates - you can't call two different overloads of a method based on the concretization of a generic type, because the concretization doesn't happen at compile time.
It would look like this:
public void Func<T>(Dictionary<T, int> somename)
But going by the description, there's a good chance you can't do this (or actually you could, but you'd have to manually test the type of T, and that's arguably a worse situation than you're on now).

I'd suggest looking at whatever part(s) of the functions that are truly identical (including types) and factoring that logic out of the two specific implementations, into a (private) sub-function.
Or use the generic implementation as suggested by Harold.
Either way, be careful to avoid falling back to an object-based (non-generic) implementation, because boxing-unboxing will impact your performance.

Hi,
With my Form_Load() I wish to set my 150'th Row as my TopRow, while the DataGridView gets visible. For that when I setup the currentcell Property its working fine. no prolem.
But when I try through the FirstDisplayedScrollingRowIndex() property its not working.
Its Not Working
dataGridView1.Rows[150].Selected = true;
dataGridView1.FirstDisplayedScrollingRowIndex = 150;
dataGridView1.Focus();
But the below is working
dataGridView1.Rows[150].Selected = true;
dataGridView1.CurrentCell = dataGridView1.Rows[150].Cells[0];
dataGridView1.Focus();
