Ok, even if you make use of a batch file that starts the UI application on the remote PC side ... does it not work, looks like there is no way around this one ?? Confused | :confused:

adapter.fill method Catch and Finally block do not execute

You cannot create an interactive process remotely. This is so someone can't start an arbitrary application and trick someone into entering usernames and passwords or credit card information or some other sensitive information.

I have the below lines of code in a windows service.

When I run the service locally this works fine. But on the server it creates an issue on line no 6 "_dAdapter.Fill method". I can not debug it on the server as there is no VS 2005 installed.

The issue is the program just hangs and do not move further to line no 6 and it never comes on catch. It do not come on Finally block too.

Please advice.

1. try
2. {
3. ...
4.OracleDataAdapter _dAdapter = new OracleDataAdapter();
5. _dAdapter.SelectCommand = _oCom;
6. _dAdapter.Fill(dsGetOrder, "process");
7. }
8. catch (Exception ex)
9. {
10. ...
11. }
12. finally { }

Regards,
Pavas

But you can add instrumentation and logging to get a view of what is happening inside your application.

Is your live database bigger than your test/development database? The issue could be that it is attempting to load in all that data into memory.

Hangs for how long ? Sounds like it's just taking a long time to execute the call.

Default character sets for fonts and foreign characters

hi all

I seem to have run into a problem and was wondering if anyone else had seen someting similar or could point me in the right direction.
I have an application that displays user inputted text in a choice of fonts (they choose). However when somebody inputs cyrillic text it doesnt show into the correct font (AbbeyRoad NF) but displays it in Arial. I thought this was because I set a default font face and then try to reset as the chosen one but this isnt the case, as AbbeyRoadNF doesnt have the cyrillic char set in it I'm assuming its defaulting to Arial internally but I can't see where this is happening as its not throwing any errors and I need to catch where this happens so I can alter the font for the print processing (which doesnt default to Arial).

has anyone heard of anything like this ? Any thoughts at all welcome.

thanks

DataGridView and DataSet , Update and AccpetChanges

Hi,

the situation is this :

i have a datagridview bound to a dataset.

when i click on a button i've got on every datagridviewRow i need to update the changes in the same row, the thing is that i need also to change a column named "status" in the same row

here is the event :

private void dgvCalibrtion_CellContentClick(object sender, DataGridViewCellEventArgs e)
 {

     if( e.ColumnIndex == 6)
     {
             UpdateCalibrtionData((dgvCalibrtion.Rows[e.RowIndex].DataBoundItem as DataRowView).Row, e.RowIndex);
             TA_CalibrationData.Update((dgvCalibrtion.Rows[e.RowIndex].DataBoundItem as DataRowView).Row);
             dS_StationManager.T_CalibrationData.AcceptChanges();


     }
 }

the thing is that the change in the column status //Cell[2]// never send to the DB
the Datagridview shows the string ("Valid", ... ) but does'nt pass the change to the *.mdb,
Neither the color of the string is changed.

but all the other manually changes to the datagridview ( input from user ) is updated o.k.
//Here i'm changing the value of the cell myself//

private void UpdateCalibrtionData(DataRow dgvDataRow, int RowIndex)
{

    DateTime ncalTime = (DateTime)dgvDataRow.ItemArray[3];

    if (ncalTime < DateTime.Now)
    {
        dgvCalibrtion.Rows[RowIndex].Cells[2].Style.ForeColor = Color.Red;
        dgvCalibrtion.Rows[RowIndex].Cells[2].Value = "Date Expired";
        return;
    }

    if (ncalTime > DateTime.Now)
    {
        if (ncalTime < DateTime.Now.AddDays(SM_ApplicationData.Instance.CalibrationThreshold))
        {
            TimeSpan dayDiff = (DateTime.Now - ncalTime);
            int dDays = -(dayDiff.Days - 1);
            dgvCalibrtion.Rows[RowIndex].Cells[2].Style.ForeColor = Color.Orange;
            dgvCalibrtion.Rows[RowIndex].Cells[2].Value = "will expire in" + dDays.ToString() + " Days";
            return;
        }

        dgvCalibrtion.Rows[RowIndex].Cells[2].Value = "Still Valid";
        dgvCalibrtion.Rows[RowIndex].Cells[2].Style.ForeColor = Color.Green;
    }
}

are you able to create a connection to the server and query a database?

you will need to build your query string dynamically based on the input from the user.
make sure you use parameters thou and not direct text appends

Well, what specifically are you having difficulty with? Writing the query? Writing the code to query the database? Writing a stored procedure? Figuring out how to pass the parameters? Something else?

That's a very bad solution to an unknown problem. RAW packets can only be created by an admin level account since Windows XP Service Pack 2.

storing Data from textbox created At runtime?

public partial class try1 : System.Web.UI.Page

base.OnInit(e);
string query_ddl = "select range from DDLValue";

How insert Data from Textbox at Button_click

Tom Deketelaere14-Jan-09 1:25

14-Jan-09 1:25

At first glance there are several things wrong with this code.

1: you create several textbox controls but you don't set there location, so unless 'PH1' is a tablelayoutpanel or flowlayoutpanel all your textbox's will be shown on top off each other.

2: why add a new eventhandler to button1 for every textbox you create.
If button1 is created at designtime you don't need to add an eventhandler to it in code.
If button1 is created at runtime (off which there is no code here) adding it only once should be enough.

3: as to your question, the way you wrote it here you have 2 options.
Having a array variable (global) and adding all your textbox's to this array, then in button click event iterate this array.
Or iterate all the controls in 'PH1', check if there type is of the type textbox and get the text that way.

Tom Deketelaere14-Jan-09 2:44

I knew this question was going to come.

Did you at least try to do anything I said?

I don't write c# so can't help you with that

But here is some vb.net code (easy to convert)

for each c as control in PH1.controls
if c.gettype.equals(gettype(textbox)) then
dim txt as textbox=c
dim textstring as string = txt.text 'now you have the text in the textbox
end if
next

What's the error? please be more descriptive when asking questions.

developer.ravish wrote:

What do you mean by this. If you mean how can you just put 'txt1.text' in your code and get the text form that dynamicly created textbox, then you can't (well maybe with reflection but I don't know).
