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.

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();

AS a (bad) workaround, you can place a bmp is your resources and convert it into an icon:

Bitmap bmp = (Bitmap)resources.GetObject("myBMP.bmp");
IntPtr Hicon = bmp.GetHicon();
Icon newIcon = Icon.FromHandle(Hicon);

Then do what you want with it.

Using MQSeries with C# :: Cannot connect to queue on remote server (dll error)

6-Dec-06 19:41

I'm trying to implement message queuing in C# .net using MQSeries .. I have the Websphere server installed on a machine and i've tried implementing queuing on that machine .Local queuing without using channel information works fine on the machine where the server is installed .I tried installing MQ client on the client machine but it still is unable to connect.Everytime i try to connect to the system remotely and access the queues , i get an error saying dll not found.I tried to resolve this by copying all dlls frm the bin folder of the MQ client to system32 but that didnt help.

The exception is raised when the queue manager object is initialized . Even when i try to connect to the server from the same machine using channels ,it gives an MQRC_Environment_error .. or MQCONN error.Does anyone have a solution ??
