Cool. When will I expect them? Have you posted them first or second class?

Well, the poster's profile claims that Job Title is Engineer.  I'm glad we're working on ice cream and not skyscrapers. If that's the claim, then maybe some harshness is in order. If he/she needs homework help at the last minute "plz urgent", google can give results in under a second. Problem better phrased as "I'm having trouble understanding try/catch and making custom exceptions. Does anyone have a simplified explanation, my text is convoluted and the examples I've found on the net are not making much sense to me." Posted with the utmost respect for Mr. nelo_.

I don't think Pete's being too harsh at all. You're right, "gone are the days when students would..." and that's the problem. The problem isn't resources like Google and CP. The problem is that students expect instant answers and other people to do their homework because they can't be bothered to learn the material and the professors (and/or tutors) are more than happy to teach to this increasingly downward trend.

Hi,
i'm trying To Display a Notification Form To the User Telling him that tha App is loading
Sql DataBase.
The frmLoading Load From Contains Label that states "Please Wait While Loading"
but when the Form Loads it do not shows me the Label and the Cursor over the Label is in
TimeClock Mode Like it's Waiting For Something!!!!,
The Thing is that The From is Active and can Be Moved
The Operation of The Fill Methods Takes Very Small Time Slice if The Connection Succeded
so the Form is immediatly Closed after Shown.
if the Loading Was Not Succesful
The Fill Methods Will Wait For A While if the Connection To SQL Server Could Not Be Done
The Point of the Form is to Give the User the Feeling That Something is Happening
I've tried a Thread But Got The Same resaults
Help AnyBody 
Here is The Code :
<br />
try<br />
{<br />
frmLoading Load = new frmLoading();<br />
Load.Show();
<br />
TA_OCards.Fill(dS_CarManager.T_OpenCards);<br />
TA_CCards.Fill(dS_CarManager.T_ClosedCards);<br />
TA_Dest.Fill(dS_CarManager.T_Destinations);<br />
TA_Users.Fill(dS_CarManager.T_Users);<br />
TA_CDetails.Fill(dS_CarManager.T_CarDetails);<br />
<br />
Load.Close();<br />
<br />
}<br />
catch<br />
{<br />
MessageBox.Show("Server is Not Connectet, Please Try Later", "DataBase Error");<br />
this.Close();<br />
}<br />
<br />
Have Fun

If you get thrown into the catch block, you don't end up closing the fmrLoading form. Try rewriting this as:
using (frmLoading loading = new frmLoading())
{
loading.Show();
try
{
TA....
}
catch ( SomeAppropriateException here )
{
this.Close();
}
loading.Close();
}As a general note, try wrapping your code blocks in pre instead of code tags and don't catch general exceptions without actually attempting to catch more specific exceptions before hand.

Hi
I have a picklist of 68 items. This is returned from a web service as a picklist. I would like to display the items from the picklist in a datagrid.
I have added the picklist items to an array then tried to display the array in the datagrid. Unfortunatly Im nto getting anywhere.
Heres my code
m_AddressList = base.AddressPickList;
PicklistItem[] atItems = m_AddressList.Items;
gridAddresses.DataSource = atItems;
It all builds, but nothing is displayed.
I would appreciate any help.
Thanks in advance.

is this ASP.NET? Have you tried calling DataBind() on the grid?

Hi Thanks I had just realised that I had missed
gridAddresses.DataBind();
Helps!!
thanks for your help

Is there a way to run a potentially long operation at shutdown while (displaying progress and the ability to cancel to the user). Something like the synchronising folders that happens after the user has shutdown on a domain computer.
I do not want to prevent shutdown or anything like that, just allow my application to finish any necessary processing as part of the shutdown process.
|

Hi!
You'll have to subscribe to the (static) SessionEnding event of SystemEvents class and perform your operation in the corresponding event handler.

Thanks, I have tried hooking that event and I can start the process when I receive the event but I only have a limited time (very short) to respond before Windows displays a dialog saying the aplpication has not closed (the one with the progress ticking down and "End Now" button), this would not be acceptable. I was hoping there was a way to run a long operation after the user session has ended but before the machine has shut down, such as the offline files synchronisation process in Windows.

I don't know if there's a way to tell windows to postpone shutdown (perhaps there's a registry key for this), but right now I see only 2 alternatives:
1) Cancel the shutdown while your shutdown process is still running or
2) Start the shutdown process in a separate thread and don't cancel windows shutdown. But then your shutdown process can be aborted unexpectedly, so this might not be a good idea (depending on the real use case).

Also, I have handled event "LocalReport_SubreportProcessing".
When i run the ReportViewer, i can see the data but at the top it displays: "Error: Subreport could not be shown ".
Please tell me what is missing and how could i fix this problem?
Thanks & Regards

Are you displaying the subreports in a list?

Thanks carbon_golem,
No, i am not displaying subreports in a list.
I added subreport control from ReportItem toolBox to the main report.
I have created separate .rdlc file for the subreport and mapped with SubReport. Still the problem is not resolved.

Hello,
I'll try to explain what I'm trying to do as sufficient as possible, or better I'll give an example. Usually when pressing F1 in an application we get help dialogbox. I want to do something like that. When I press F6 let's say I want to print. But I can't find a listener that does that. KeyDown only works when an object has focus. Does anyone know how to trigger an event when there is no focus. For instance, an MDiParent doesn't have focus when children are active, but I want to get the help dialog. Does anyone know how to do this? Thank you in advance.

You may add it to the key down event of the parent form itself
Thanks
Laddie
Kindly rate if the answer was helpful

If you mean something like
this.KeyDown += System.Windows....
It doesn't work, because KeyDown works when the object has focus and it doesn't a Child does.
|
|
|
|
|
this.KeyDown += new System.Windows.Forms.KeyEventHandler(this.Form1_KeyDown);
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
MessageBox.Show(e.KeyCode.ToString());
}
This works perfectly fine for me as long as the form is the active window.
Thanks
Laddie

Yes I know but the form isn't the active window
