Hi,
In our window based C#.net application, we are getting this "Window Handle Error" in a random manner. Initially we thought it could be a memory issue but sometimes even if there is enough memory, the same error comes. we are unable to track the root of this error. Any input regarding this error is most welcome.
Thanks,
Madhan

When the error occurs - what does the stack trace look like? What happens immediately prior to the error?

You may want to open Task Manager, go to the View menu and Select Columns. Turn on the Handles column.
Then run your application and start using it. If you application continues to accumulate handles and starts to climb over, say, 1,500 handles, you've got a handle leak problem. Your code isn't releasing unmanaged resources, like GDI handles, file handles, window handles, ... This means you're not calling .Dispose() on objects, like Graphics, Brush, Font, Pen, forms shown with ShowDialog(), ...

string URL="http://www.someaName.com/ccp/index.jsp?pg_name=ccpmapp/individuals/savings/page/retirement_money_market";<br />
object oMissing = null; <br />
<br />
HTMLDocumentClass objects=new HTMLDocumentClass();<br />
<br />
axWebBrowser1.Navigate(URL,ref oMissing,ref oMissing,ref oMissing,ref oMissing);<br />
<br />
while(axWebBrowser1.Busy)<br />
<br />
{<br />

This doesn't really compute. What is it you want your app to do ? What bits do you need ideas for ?

Have the program check for upcoming events every maybe 15 minutes, or whatever you lowest reminder time is. If the event is close then remind the user, however you wish to do so.

If you have a client, ask them. If you're doing this for yourself, ask yourself how you want it to work.
If it's homework, either ask your teacher, or assume they'll accept anything that literally meets the spec.

Some basic ideas?
It could implement a calender, and possibly remind the user when something he planed comes up...

Hi guys
Using WebBrowser object to open an email attachment in win form(C#), I am facing given below probs, Can any one help me on this?
Issue: If an excel or word document is already opened in your system and at the same time you try viewing an email with an attachment of MS Office(Excel/MS Word) through my application (win form), It gets opened in the Form as well as it creates and open a separate instance of the same attached document in already opened MS Office(Excel/MS Word), resulting the opened document(MS Word/Excel) hangs and there is no way out to make the MS Office document(word/Excel) active unless you close my application.
The given below is the code to open the attachment
if (filePath.EndsWith(".doc"))
{
wbExcel.Visible = false;
wbOthers.Visible = false;
wbPDF.Visible = false;
wbWord.Visible = true;
wbWord.BringToFront();
if (wbWord.Url == null || !filePath.Equals(wbWord.Url.ToString(), StringComparison.InvariantCultureIgnoreCase))
wbWord.Navigate(filePath);
}
else if (filePath.EndsWith(".xls"))
{
wbWord.Visible = false;
wbOthers.Visible = false;
wbPDF.Visible = false;
wbExcel.Visible = true;
wbExcel.BringToFront();
if (wbExcel.Url == null || !filePath.Equals(wbExcel.Url.ToString(), StringComparison.InvariantCultureIgnoreCase))
wbExcel.Url = new Uri(filePath);
}
Where wbExcel and wbWord are object of type WebBrowser
Hints: It seem the default behaviour of MS Office which throw some exception which need to be tackled.
Thanks & Rgds.

Your text is all one node, so to break it into lines, you need to write some code to split the string. If it contains newlines, you can split on those ( use the string.split method )

i am studying on a hotel reservation prject. i use an access file and a table which has fields resstart and resend. we dont make reservations directly on rooms. the system determines the room number of a guest who's checking in from empty rooms at checkin time. the hotel has 45 rooms. so my problem is getting how many reservations include days between the given resstart and rezend values.
suppose that a customer has a reservation between 23/05/2007 and 29/05/2007. and a new customer want to make a reservation between 26/05/2007 and 28/05/2007. so if i make a query based on resstart and rezend values than the first reservation will be ignored and second reservation will be accepted even if there will be no empty room between those days.
please help me,sorry for my english

After this line this error occure => sqlconnection1.open();
Sqlexception was unhandle:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.
