Very strange to see that. But how does it work on client side is still a question. Or does it work only on localhost? I think it will work only on localhost. Have you tested this?
Also you can see the same discussion at http://p2p.wrox.com/topic.asp?TOPIC_ID=11595[^] Smile | :)

Just checked it. MessageBox is always populated on server desktop. It will create hell when thousands of user will access the site and there is message box for frequently occuring errors or events. This is same like showing message box from a console application. I dont see any use unless and until somebody is continously sitting in front of server and tracking the errors. I found this link.

I agree, it only seems useful for development purposes.

Are you talking about a datagrid or datagridview?
If so, is the dropdownlist a column within the dataset?
I'm going to need a little more information about the control you're trying to resize, what controls it is in, and where the data is coming from.

Hi,
I'm binding the value of a dataset to a dropdownlist.I need to change the column width.

Here is the code:

StringBuilder stbSQLStatement = new StringBuilder();
stbSQLStatement.Append("SELECT [RiskCatID] ");
stbSQLStatement.Append(" ,[Description] ");
stbSQLStatement.Append("FROM [MARTblRiskCat] WITH (NOLOCK) ");

DataSet dtsResult = new DataSet();
dtsResult = QueryData(stbSQLStatement.ToString());
ucbRiskCat.DataSource = dtsResult;
ucbRiskCat.DataBind();

I need to reduce the column width of the columns displayed in the dropdownlist.

Thank you,
Regards,
Deepa!

I want use the metod public T Find (Predicate<t> match) to find an string in myList.
But I have no idea how can I find a string as a parameter.

I know only this way:
List<string> mylist = myList.FindAll(demo);

Is this way possible:
List<string> mylist = myList.FindAll(demo(object x));

From the documentation, it doesn't look like it would work, but I would try it to see if it did. Maybe the error message will give you insight.

As a (bad) workaround, create a search criteria member variable of your class.
for example:

private string FindAllSearchCriteria;

Set that before the findAll

this.FindAllSearchCriteria = "whatever";

then call

List mylist = myList.FindAll(demo);

Inside your demo method, use the this.FindAllSearchCriteria as your criteria for the search.

win form datagrid changes

Hi,
Currently I use the following method in the presentation layer to capture the changes in a gridview control on a windows form:

DataSet data;

//Added records...
data = gridViewDataSet.GetChanges(DataRowState.Added);

//Modified records...
data = dsEmployeesList.GetChanges(DataRowState.Modified);

//Deleted records...
data = dsEmployeesList.GetChanges(DataRowState.Deleted);

So basically I loop through each record in the grid (In the presentatioin layer) and call the necessary stored procedures (in the datalayer) according to the state of the row.

This works fine.

My question is, there is no transaction.
So, should I stop using this method and use .update of DataAdapter or is there another method please?

I was thinking about transaction of connection but do not think I can use this in the presentation layer.

Hope you follow what I am asking.

Thanks

Hi,
You can try using DateTime.DaysInMonth(2006, 10);
Where first parameter is an year and second one is month. You can put int i and run the same function for 12 times.

Try doing this.

Array.Sort<string>(new string[] {"j", "a", "y", "a", "n", "t"});
Array.Reverse();

hi
you can do this:

<br />
String s = "the string to convert";<br />
char [] array = s.ToCharArray();<br />
char[] newArray;<br />
int count = 0;<br />
for (int i = array.Length - 1; i >= 0; i--)<br />
{<br />
  newArray[count] = array[i];<br />
  count++;<br />
}<br />
String newString = new String(newArray);<br />

there should be more flexibale methods.
but this came to my minde right now knowing that you have some conditions that it should be done using an array.

hope it helps best regards

Try this...

string string1 = "String To Reverse";
string string2 = string.Empty;
StringBuilder sb = new StringBuilder();

char[] sArr = string1.ToCharArray();
for (int j = sArr.Length - 1; j >= 0; j--)
sb.Append(sArr[j].ToString());

string2 = sb.ToString();
