I just ran into this problem too. If you are binding your DataGridView to a data object such as a DataTable:
dvBalances.DataSource = _table
When you want to clear the rows in the DataViewGrid do this:
_table.Clear()
Something like:
dvBalances.Rows.Clear()
won't work.

hello
On client side:
<br />
oRemoteObj = (RemoteObj)Activator.GetObject(typeof(RemoteObj), strUrl);<br />
Apart from actually invoking method on "oRemoteObj", is there any convenient way to test if the proxy/channel is still alive?
Thanks

i have Datagridview on a form and at runtime i attach DataGridViewComboBoxColumn with datagridview and also populate that DataGridViewComboBoxColumn control. when i am selecting data from combo on grid and click on another button to read datagrid's data in loop, i always found no data from the cell where combo appear. so please guide me how to push the data from combo into datagridview cell when i move from that cell where combo appear. please help me with code snippet.
Thanks

Instead of reading the data from the cells, I think you should read the data from the underlying datasource (datatable for example). Special columns like combobox column, image column etc. act each a bit differently and there is no extra cell for the data in those columns.

double t;
t=(0.4,0.2,0.4);
this shows error... pls help me how to get each values seperately as a double
thanks
the quieter u become more u hear

|

hmm, what does this mean (0.4, 0.2, 0.4)? Is this a tupel or an array?
|
|
|
|
|
its an array.....
i'm struck....
pls help me
the quieter u become more u hear

If it is an array then you should define it like this:
<br />
double[] aValues = new double[3] { 0.4, 0.2, 0.1 };<br />
|
|
|
|
|
hmmm...
but if i have to pass many lik this
for example
a = { 0.6, 0.4 };
b= { 0.4, 0.2, 0.1 };
c= {0.2,0.5,0.3};
double[] b = new double[3] { 0.4, 0.2, 0.1 };
how should i define for a and c
help me

do you mean as a 2D array?
cause otherwise that is a poor question

sss... 2d array man

double[,] da = {{0.4, 0.2, 0.1}, {0.5, 0.2, 0.6}};
Access like so:
da[0, 1] = 0.2
da[1, 2] = 0.6
note: each array must have the same depth, although these can be default values if you do not wish to use them.

Or use jagged arrays
double[][] da = new double [][]{
new double [] {0.6, 0.4},
new double [] {0.4, 0.2, 0.1},
new double [] {0.5, 0.2, 0.6}};

Well, the same:
<br />
double[] a = new double[] { 0.6, 0.4 };<br />
double[] b = new double[] { 0.4, 0.2, 0.1 };<br />
double[] c = new double[] { 0.2, 0.5, 0.3 };<br />
What do you want to achieve exactly? Do you want a list of double arrays? If you can give us the part of your code where you need this, we could help you a bit better.

actually i have to convert an algorithm from vc++ to c#...
its a big code....
do have any idea in viterbi algorithm
and hidden markov model
the quieter u become more u hear
|
|
|
|
|
No sorry, no idea about these algorithms... maybe the vc++ gives you an intention how the double-arrays are handled (using a list or sth similar)
|
|
|
|
|
why dont you post a part of the original code you are stuck tranlating and maybe someone can help offer you an alternative c# version
|
|
|
|
|
i will post it tmw friend.....

double t;
t=(0.4,0.2,0.4);
if you want as array it needs to be;
double[] t = {0.4, 0.2, 0.4};
OR
double[] t;
t = new double[]{0.4, 0.2, 0.4};
then you access each double using the array index value for the required double:
d[0], d[1], d[2] etc...

Hi
I want to find all children at a specific level in a treeview with a specific name. for example I want to find all children with full address :"site/people/person/name"
Using visual studio 2005 how should I do this?
Thanks in advance
|

The treeview's nodes collection contains a function that can return a node with a given key.
Each node has its own node collection for its child nodes.
Using these, it's fairly straightforward to write a function that recurses this structure.

Hi everybody!
I have a problem with the XmlSerializer:
When serializing a property (string) containing only a TAB "\t", I get only an empty string.
The serialized object looks like this:
"<Separator> </Separator>" (There really is a tab  )
Here's my property:
protected string separator = ";";
public string Separator
{
get { return separator; }
set { separator = value; }
}
I know I could make a char property, but this would be a workaround for this problem, not the solution.
Any ideas?
Thanks, Phil
I won’t not use no double negatives.

In XML, all whitespaces are treated as a single space, even when there are many together. When there is only whitespaces, it is treated as an empty string.
Maybe you could try to put it in a CDATA section (if you have control over the XML itself).
