Can you give me an example or code. I can't see how to relate a "DataGridViewTextBoxColumn" to my column. Thanks for your reply and help.

CType(Me.DataGridView1.Columns(0), DataGridViewTextBoxColumn).MaxInputLength = 10

Thanks you're a life saver

I KNOW ENOUGH TO BE DANGEROUS BUT HERE GOES...
I've created a windows application with a Flash file embedded in the WebBrowser URL. Stand-alone, the Flash file works fine but my application allows only one button click to invoke an action. After that, the buttons become useless.
I was told this is an unresolved VB bug and should add the following VBScript code in my web browser:
sub fs_fscommand(ByVal command, ByVal args)
Call fs_doFSCommand(command, agrs)
End Sub
Where would I insert this and does the script need further editing for my specific application?
Any light shed on this problem would be greatly appreciated.

I have created a "Mainform" with the IsMdiContainer Property set to true using VB.Net.
I have created a child form in the same project. I can get forms to load in the child form only if they are included in the mainform project.
I want to know how to load a dll into the child form.
I want to create many different Dll's (Projects) that reference the mainform functionality and then load these dll's into the child form.
IE: "Part Master" , "Employee Master", "Reports" etc.
All of these will be seperate projects so that i can work on a specific area without having to work on one huge project.
I have searched every place i can think of for the last 2 days and cannot find any help or code samples.
Any help or information will be great!

This I think is a simple question.
When I try and run this piece of code
For Each Dir As String In My.Computer.FileSystem.GetDirectories (DriveComboBox.SelectedItem, FileIO.SearchOption.SearchTopLevelOnly)
FolderListBox.Items.Add(Dir)
Next
When it gets compiled the messages
Name 'FileIO' is not declared
Name 'My' is not declared
I am using Visual Studio 2003.
What imports should I copy in or is there another way of getting these values.
|

|
|
|
The My and FileIO namespaces are only in VS2005.
Trinity: Neo... nobody has ever done this before.

Hi Praveen,
You are actually asking the wrong people, this being the Visual Basic / VB.NET Q&A. But as the languages are similar, I suggest trying something like:
<br />
Dim Emp_ID as string<br />
Dim MySqlSentence as string<br />
Emp_ID = DropdownList.SelectedItem<br />
MySqlSentence = "SELECT Emp_Name FROM Employee_table WHERE Emp_ID = " & Emp_ID<br />
Good luck,
Johan
My advice is free, and you may get what you paid for.

In VB2005, most of the events pass the sender object as a parameter through the vent itself:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click<br />
Is there any way to get the object's name (not the type) of the sender? .ToString returns its type and I'm looking for a way to get "Button1".
I want to handle the xxxx_Click event for several buttons in the same event and without adding a new parameter with an id or something like that.
Thanks in advance,
Marc Soleda

you can use :
if ctype(sender,button).name="Button1" then
'do a task
end if

Or better yet, cast to Control, which has that property and is more 'guarenteed'.

Ok, that's right for a control but, if it isn't, and it's an object instanciated from a class library that after doing this cast doesn't have the Name property, how could I know it?

I think you know that the answer to your question is NO, not by the way already mentioned; however, what I understood you are saying is, in general, all objects will have some name, how can you get access to that name?
If that is the question, then I think that the only way is to check for the object type and access its name by the method appropriate to that object type.
for e.g., maybe you need to use reflection to get the class name OR
you can get the type name which should be the class name - I am not sure. Just my thoughts.

Using reflection I just can get the class name/type. What I'm looking for is its name that, even it's not a control, I have instanciated an object as a class type and with a name. Isn't there any way to retrieve it?

No, using reflection you can find properties and you can get their values.
Marc Soleda wrote: I have instanciated an object as a class type and with a name.
If you mean the variable name, you can't get it. If you mean a property on the control, you can get it with reflection, but if you don't know what the variable name is, then you're going to have a hard time.
An event handler is always going to have a control come in, I assume you mean the question more generally. It's unusual for your code to take an object and for you to have *no* idea what the object will be.

Not always if it's an object's class - not a control - that raises an event when a something happens: I file has been received, ...

Unusual maybe but If I handle an event from several objects in only one eventhandler, then I need to differenciate between them to know which one has been.
At last, I've solved by using Object.ReferenceEquals that determines if two objects are the same instance.

Try
If sender.name="A Name" Then
'Do A Task
End If
Catch ex As Exception
MsgBox("The object dosn't support name property")
End Try

You can't, as it doesn't have a name.
What you are looking for is the name of the variable the holds the reference to the object. The problem is that there can be more than one variable referencing the object, or if there is a single variable, that variable might not have a name either, e.g. if it's part of an array.

That's the key! It doesn't have a name but I can compare two objects to know if they are the same instance that, for my purposes, is what I need: Object.ReferenceEquals
