Hmm, interesting. I've never needed to trap such an event so I don't know what's going on under the hood. Have you considered creating a custom event:
public class CustomMenuStrip : MenuStrip
{
//use this method instead of: DropDownItems.Add()
public void AddDropItem()
{
this.DropDownItems.Add();
OnDropDownItemAdded();
}
public event EventHandler DropDownItemAdded;
protected void OnDropDownItemAdded()
{
if (this.DropDownItemAdded != null)
this.DropDownItemAdded(this, null);
}
}
This maybe a shot in the dark but it may help you out.
Cheers,
Richard

well, it will only work on runtime anyway I got something different that is I should add another Items Collection property like ItemsX that will have custom ToolStripItems collection

Hi All,
I would like to be able to read and write directly to the NTFS and or FAT.
Can anyone point me in the correct direction to do this using c#, failing that c++
I wish to append extra information about the files and folders that is specific to my company.
many thanks for your help...

I dont know if this could be the solution to your problem (in NTFS anyway) but take a look at Alternate Data Streams[^]
A brief search gives this CP article ADSdotNET: A DLL for using alternate data streams from .net languages[^] in C++.
Maybe, if you have a bing about, you will find something in C#.
Hope this helps.

Hi!
I am new to programming with SQL so I really need help on this one. After I finish an application with no errors or bugs, i tried to launch it in different computers. However, most computers encouter SQL errors while loading the application, either a timeout error or the application simply crashes due to the inability to load the data from an SQL database.
My questions are the following:
1. Do you need an SQL server running in the computer where you will deploy the application? Though in some computers, the application worked even though they do not have an SQL Server.
2. Should I modify something in the connection string when I am already deploying the software? Is there a difference in the connection string when the program is running in my computer and in other computers?
My connection string is this:
"Data Source=.\\SQLEXPRESS;AttachDbFilename=|DataDirectory|\\MyDatabase.mdf;Integrated Security=True;User Instance=True";
I tried modifying the timeout but the error still remains.
3. Where could I have missed something?
Sorry if I am missing something trivial here.
Thanks in advance for those who will respond! You'll really be helping me a lot.
Thanx!

I would start by looking at the integrated security. When set to true the currently logged in windows user account will be used to try to access the server. If you haven't given the individual accounts permission to the database security could be stopping you.
You could fix this by setting the integrated security to false and then specifying a specific SQL UserID and password.

Also doesn't look like you are specifying your server name in the connection string. SQL will only have to be installed on your server but the other machines need to know where that is.
This is a pretty good primer on connection strings: http://www.connectionstrings.com/sql-server-2005[^]

this.Heading1 = _heading1;
this.ReportType = _reportType;
this.Grid = _grid;
WriteReport();

Hi all...
I'm trying to write to a file with the XmlDocument class. I used the Save(string) method which gets a file location and saves the XML to it. the thing is I get an exception:
"The process cannot access the file 'c:\scene.xml' because it is being used by another process".
What is the problem? how can I overcome this? (I want to load the file and then to be able to save on the that file)
some code:
this happens when loading of the file
_currentXMLFile = openXMLFileDialog1.FileName;
System.IO.StreamReader myXMLFileStream = new System.IO.StreamReader(_currentXMLFile);
XmlTextReader myXMLTextReader = new System.Xml.XmlTextReader(myXMLFileStream);
_myXMLDocument = new System.Xml.XmlDocument();
_myXMLDocument.Load(myXMLTextReader);
myXMLDocument is defined at the start of the program so it will have the program's lifespan.
this happens when trying to save the XML document into a file, and throws an exception:
myXMLDocument.Save(fileName);

Hi,
if you're running Windows Vista or higher, you are not authorized to create files in certain locations of your boot partition; the top level directory is one of them. So choose another location, there is an excellent way to get some here: Environment.GetFolderPath() Depending on the kind of file and data, look for ApplicationData or MyDocuments or ...

Actually I'm using windows XP...
I tried the procedure (load and save) on many locations and it still throws the error.
it there a way to load and save the same file, did any one tried that??

Make sure you close the file where you load it, the "another process" part of the error message often is incorrect.

ok, even though the System.IO.StreamReader is defined within a function?? (the function ends before the save action)

yes, you have to close or dispose of it explicitly, or use a using statement which is a way to get it disposed of automatically. There is no "stack semantics" stuff in C#, and the GC will only execute finalizers if and when new memory allocations cannot be satisfied without collecting first (and even then finalizers run on a low-priority thread), so that can take a long time to happen.

Closing the streamReader did solve the problem... you are awesome!
one more question on a relative topic:
XMLNode myXmlNode;
for (int i=0; i < 2; i++)
{
myXmlNode = new XMLNode;
}
will the GC collect the first two allocations of the XMLNode? and when?
|
|
|
|
|
Hi,
you have to add () to make that compile...
and I see only two allocations. The first is collectible right away, as the only reference (in myXmlNode) gets overwritten by the second one; I can't see where the second one becomes collectible, as the enclosing code block is absent.
And collectible isn't the same as collected, as I already explained.

Can I get the code of any *.exe file?? If yes how?
because I lost my source code for my application. But I installed it before it is lost ... and I have the exe file with me ....... what do u recommend me to do??
|
|
|
|
|
Sure, get Red Gate's Reflector (previously from Lutz Roeder), for native programs, well, there is a thing called Boomerang, but it is not that good so you'd be better off with a disassembler for native code.
|
|
|
|
|
IMO, given your previous posts it's doubtful you want this for genuine purposes. It's more likely you want to decompile someone else's application, and, again from your previous posts, it's highly unlikely you would even understand it.
If this is not the case, then it's a good lesson for you in how to use source control and backups.
only two letters away from being an asset

hey dude ..... that is not the case .... i didnt know that exe files will be converted to back ..... after I know it(i.e yesterday) I remembered there was one application that I did for my customer and I remembered I lost it with virus ...... but the exe file is still on my pc .... that is why i post this question... if you can help am here...
Thank you
