The .designer.cs files all contain the correct namespace. I've tried rebuilding - no success. Cleaned the solution as well. Strange thing is that I can't access the folder in my using directives.

No, both projects reside om one machine running xp. I'm going to create new forms in the current project and rename them exactly the same as the forms in the other project and then attempt to replace them. Hopefully this'll work.

Linq To Xml help

okay i need some help with my Linq to Xml code, i want to check if the new XElement that im about to create has the same XAttribute as an old XElement, if it has the same XAttribute as another XElement then instead of adding a new XElement with same XAttribute i want it to replace the old one.

This is my c# code:

string calendarxml = "C:/Users/Miro/Documents/Visual Studio 2008/Projects/Post-it/Post-it/CalendarXml.xml";
                  XElement doc = XElement.Load(calendarxml);
                  XElement root =
                                    new XElement("CalendarNote",
                                    new XAttribute("Date",
monthCalendar1.SelectionStart.ToString("dddd dd MMMM yyyy")),
                                          textBox1.Text);
                        doc.Add(root);
                        doc.Save(calendarxml);

and the output in my xmlfile looks like this:

<calendar>
   <CalendarNote Date="söndag 17 maj 2009">asdasd</CalendarNote>
   <CalendarNote Date="lördag 16 maj 2009">123123</CalendarNote>
   <CalendarNote Date="söndag 17 maj 2009">asdad</CalendarNote>
   <CalendarNote Date="lördag 16 maj 2009">123123</CalendarNote>
   <CalendarNote Date="söndag 17 maj 2009">asdads</CalendarNote>
</calendar>

i dont want to have three söndag 17 maj 2009 and two lördag 16 maj 2009, i want just one, instead of adding a new one with same attribute i want it to replace the old one.

remoting security/permissioning exception...

hello

I ran into this, apparently it has to do with remoting permissioning. I have no idea where to start and my brain is fried... it seems like it happens after I signed my assemblies but since there're many dll's I signed not sure if I want to unsign them to confirm this.

well you could load all your rows into a datatable or something, then you create a bunch of buttons to act as page numbers, or a drop down list, based on the number of rows in the datatable.

So if you have 128 rows you could do...

int numberOfPages = numRows % 25 == 0 ? numRows / 25 : numRows / 25 + 1;

then on each button click, you load the first 25 result starting at a number obtained by...

int startRowNumber = (pageNumber - 1) * 25;

Alternatively you can get the startRowNumber and search you datasource for each page load. Depending on what your data source is will depend how you could do this. Some databases have functionality to specify a results count and start value. But you will have to look into that yourself

Life goes very fast. Tomorrow, today is already yesterday.

It depends on what you want, taking in consideration that there is a main form that shouldn't be closed, other forms could be, and you have the option of closing the forms or hiding them, preferrably is to close them of course except the main form which should be just hidden.

You can use your form as application.
In Program.cs file you can write it one by one.

Application.Run(new Form1());
Application.Run(new Form2());

If you can think then I Can.

c# BHO Issues

14-May-09 1:05

Hi,
I had a small application of BHO using c#.
1. How to know Header Information when a web page is getting loaded on browser (IE)?
2. when we click a link http://mca.gov.in/MinistryWebsite/dca/help/efiling/NewFormsFees.pdf the PDF file is opened in other window (other tab),
how the pdf file is rendered in Internet explorer?
When the PDF file is opened in Ie, the PDF data is obtained packet by packet, How can I know that PDF is fully loaded on browser.

I want this to be done by using BHO as BHO gets injected, it performs the same thing for each and every instance of IE?

1. I have no idea since I've never written a BHO.

2. The PDF file is rendered by an plugin to Internet Explorer. Perhaps you've heard of Adobe Acrobat Reader??

svt gdwl wrote:

The file is downloaded to the Temporary Internet Files folder. You may want to look into the DocumentComplete events. I have no idea if they will suit your needs or not.

Socket Error

Hi all,

I am transfering a 200mb data from my socket program to the client and i have the following error during execution. I guess it because of the huge data but am not sure in rectifying the issue. I have given the error below

"An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full"

Thanks

Never seen it before but it sounds like buffer overrrun. Are you using streams so that you only work with small parts of the whole data continuously or attempting to do everything at the end?

Regards,
Rob Philpott.

Thanks for the Reply Rob

I am new to socket programming

I am trying send all the data in a single iteration.
I need to separate the data in to several segments to make sure the buffer is not full. but don't know how to do it.

Problem is caused by a recent windows patch. If you remove patch KB948609 the client side deserialization will except large datasets again. Or move to WCF as your transport method.

Assembly probing - how to instruct to look under bin folder instead of GAC?

devvvy14-May-09 0:49

14-May-09 0:49

Hello,

Assembly probing - how to instruct runtime to look under bin folder instead of GAC?

According to this article[^], runtime default behavior is to check GAC BEFORE other location.

So the fact that I added probing hint didn't change this (i.e. runtime is still binding to dll in GAC):

<br />
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"><br />
			<probing privatePath="bin;bin\Debug;bin\Release;"/><br />
		</assemblyBinding><br />

But this is NOT what I need, I actually need it to go bin folder for it?

This may be relevant.[^]

Also how can I check which version is being binded to? I launched "fuslogvw" but it is just sitting there. Nothing shows for some reason... it's giving me headache because (a) dll in GAC no debug information (even under DEBUG build)
(b) nHibernate mapping files loading - my mapping files are in bin folder, not in GAC

Thanks

sorry not exactly sure

you're saying i should implement event handlers to assembly loading/probing, set a breakpoint and see where it takes us?

I am suspecting perhaps it has to do with signing or that I've accidentally put one of System.Remoting.xxx dll into GAC (I ran a util which installed my dll's into GAC - which may have incorrectly installed System.Remoting.xxx into GAC ...)

When the run time detects it is time to load an assembly it will call that method first allowing you to provide the assembly. You can then load whatever version you wish.
