Hi all,
How do I create the descriptions that is displayed in the intellisense for my class methods. For example, I have a class with a public method LoadData(int ID) to load data from the database. So when I'm calling the method...
int _id = 2;
class.LoadData(_id
the intellisense must give me a description of what that int value must be, for ex [The id of the database value to load]
Thanks in advance

You must put the descriptions over the method.
Just type /// over the method.
Then fill the description.
If you compile this class in a DLL, then you
must change in Project, Properties, Output, XML Documentation file
and fill that one with XML file. Then you must copy that
XML with your DLL if you want to get the description everytime
you give that DLL to someone else.

Will try, thanks

Hi, I’m in process of creating dlls for Web User Controls in ASP.NET v 2.0. Let me explain what exactly my problem is.
UserControl.ascx.cs to be wrapped into dll:
public partial class Controls_Search : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
Label1.Text = testMethod();
}
public string testMethod()
{
return "Yes Iam here " + Sample.testMethod1();
}
}
public class Sample
{
public static string testMethod1()
{
return "Only";
}
}
I’ve created the dll successfully with the name Search.dll. Also i referenced this dll inside my new project. Now, whenever I load this in my page, testMethod() is being called, consequently the output is "Yes Iam here Only". That’s cool. But I should be in a position to override Sample.testMethod1()Wrapped inside the dll with my project’s App_Code class say class1.cs.
This is my new class within the project in App_Code/Class1.cs.
public class Sample
{
public static string testMethod1()
{
return "Only1";
}
}
I also tried virtual & override with testMethod1() being defined as non-static member of that class. Nothing works.
My output should be: "Yes Iam here Only1"
Thanks in advance,

You have to inherit the class to override methods in it.

I am trying to figure out how to update an activex control on a client workstation.
The client goes to our webserver and I want to then check for the existence of our activex component "CompA" on the client system. If the component "CompA" does not exist, I want to install it. If the component "CompA" exists, I want to check the version to see if it is compatible with the current version necessary for the webserver. If it needs updating on the client, I want to install the current (latest) version from the webserver.
Somewhere in all this I would like to be able to check that the user has enough rights on the client (not Guest or Limited) to do the update.
I have been trying to figure this out for a bit, starting with javascript trying to access the installed activex and query a method that returns it's version, etc.
The client workstations will be Win2000 or XP (or possibly Vista in the future). I don't have any control over whether the client workstations will have the .Net 2.0 SDK installed.
Thanx,
G

ListView is incapable of doing this even in the details mode. ListView has only one item -which is trhe first column to the left by default-. The rest in subitems which can not be accessed by user. Amuch better control that would suit your need is DataGridView. It gives you the ability to access rows/columns in a much better way. Another solution is to use one of the extended ListViews provided here in CodeProject. Just search the articles for "Extended ListView".

Actually you need some workaround: you can use the X,Y position where the mouse click occurred (the MouseEventArgs provides the coords) to check if the point is inside the rectangle of the item (listview has GetItemRectangle method) you're are interested in (for instance, the selected one if there is: MouseClick may occur everywhere inside the listview) using the X coord you can then pick the right column.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Does anybody has a suggestion on how to monitor a drive? I have a SAN device connected to a server. Let say the SAN device crashed. I want to be able to detect that the drive is no longer accisible or exist.
Samples on C++ or C# are welcome
-maybe an app running as a service!!
Any ideas are greatly appreciated

|

How about: Directory.Exists(@"D:\"); -> true or false
Just put it in a loop.

May I suggest using FileSystemWatcher class? I believe it's the best solution in your case.

1>I have to retrive and display images that are present in a MS Access Database.
2>The images have been inserted in the database by the user by using the Insert Object Functionality of MS Access so the Image is displayed as Bitmap Image for .BMP and Package for .JPEG in the DataBase Image Field.
3>I have tried reading the data in a Byte Array and then display it but it dosent work that way.
//Obtain Image in a byte array
byImageArray = (byte[])Command.ExecuteScalar();
//Read the byte array to memory stream
MemoryStream memStream = new MemoryStream(byImageArray);
//Read Image from the memory stream into picture box.
picImage.Image=Image.FromStream(memStream);
An exception is thrown is Argument Exception:Parameter is not valid.
This code works fine if we store image in DataBase Programmitically by using Byte Array,but not when we access a image that had been directly in the table by user by using Insert Object Functionality of MS Access

I dragged a DataGrid from the toolbox to a form. Then I created my own class MyDataGrid and derived it from a DataGrid. Now, the instance of the DataGrid class that I dragged to the form, say dataGrid1, I replaced with an instance of MyDataGrid.
So instead of having:
private System.Windows.Forms.DataGrid dataGrid1;
I have:
private MyDataGrid dataGrid1;
After making all the other necessary changes, my code compiled but when I go back to VStudio Design View, the form is not displaying.
I know there is something inherently wrong with how I did this, but what is the proper way of associating a user-defined DataGrid to a form?
I need to use my own DataGrid version because I need to override a mouse event.
Thank in advance!

I wish you'd have asked this question before doing this Davinci workaround!
Anyway. First you got to clean up your form -maybe by deleting it completely from your solution-. I don't know what else you and the designer have modified. So I believe "Better safe than sorry".
Now to your question.
1- Create a new project -whether to add it to the current solution or not is your choice-.
2- Choose Windows Control Library.
3- Now you have your user control. Switch to Code View.
4- Change the inheritance to DataGrid -or DataGridView as I would suggest. Why would you want DataGrid anymore?-.
5- Compile and you will have one error. Go to the line that causes the error and remove it:
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
6- Now when you build that project you'll get a dll file. Either reference to that dll file -after you copy it to other projects' folders-, or if your Control Library project is in the same solution you can reference to it directly using the Projects tab in the reference dialog box.
Big PS.
If you want to delete a thread in the forum. There is a link to the lower right of each message you post. Click on it and delete both the messages you posted earlier.

this.Text = "Form1";
this.ResumeLayout(false);
}

temp[] res = storage.InsertRecords(CommonEngine.ReadFile(typeof(temp), "temp.txt")) as temp[];
and de error says:

y is it so?

In my Windows.Forms app, I have a menu. That menu contains six menu items.
When the menu drops, I check a flag to see if the items in that menu should be disabled.
Here is the code:
private void miImport_DropDownOpening(object sender, EventArgs e)<br />
{<br />
foreach (ToolStripDropDownItem item in miImport.DropDownItems) item.Enabled = fMyFlag;<br />
}
This code executes flawlessly, disabling all the menu items when the flag is false.
However, once I add a separator bar between the items, this code throws the following exception:
Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripDropDownItem'.
Can it possibly be true that the collection MenuItem.DropDownItems contains objects of different types? Isn't that verboten?
More importantly, why on earth would they do this? Why would any item they allow you to insert in the DropDownItem list not be treated as a DropDownItem?
This makes me pretty mad, as I'll have to write much longer code to individually disable these items.
Or am I missing something? Should I not be using "ToolStripDropDownItem" in my foreach loop?
Grr. I removed the item.Enabled = value line, and it still throws the exception. An empty foreach loop should NEVER throw an exception. If it's not an "each", why the hell is it being enumerated?

I get the idea people just wait to see how often I'll Reply to myself.
Here's the code I came up with to replace that one line of code. If anybody knows a better method - say, using a different Type than "ToolStripDropDownItem " in my foreach loop - please feel free to let me know.
private void miImport_DropDownOpening(object sender, EventArgs e)<br />
{<br />
foreach (object item in miImport.DropDownItems)<br />
{<br />
Type typ = item.GetType();<br />
if (typ == typeof(ToolStripMenuItem))<br />
{<br />
ToolStripMenuItem mi = (ToolStripMenuItem)item;<br />
mi.Enabled = myFlag;<br />
}<br />
}<br />
}

Dear Joe
I can't able to clear your prob, but the below code will solve your prob.
for (int iLcnt = 0; iLcnt < toolStripDropDownButton1.DropDownItems.Count;iLcnt++ )
toolStripDropDownButton1.DropDownItems[iLcnt].Enabled = fMyFlag;
Cheers,
Chandru.

Thanks, Chandru. It turns out that ToolStripSeparators don't have an Enabled property, either, so either way I have to check the object type before setting the Enabled property.
How very inconvenient. And surprising, considering.

Hi all,
I have an application that cycles through Directories and finds Duplicate Image files (By Name).
It shows the original file name (FileInfo.Name) and the possible Duplicate (FileInfo.FullName) in the a CheckedListBox container on the form
What I want to do next is create a MouseHover Event that will show a form a bit like a tooltip with a preview of both Pictures in it.
I suppose I have a few questions.
1. Is a CheckedListBox the best solution for this to show the data? As the code runs through I store them in a List<listviewitem> which I then convert to an Array and AddRange onto the container.
2. What is the best way to get the preview to come up? I want it to dissapear as the user moves from one ListItem to another. The other issue is how can I get the MouseHover event to tell me which index I am on so I can retrieve the file paths to the imagine.
Suggestions greatly appreciated, and pointing to other online info that could me also greatly appreciated.
Regards
/TH
