I have created a Datagrid with Checkboxes. On the click of a button I am trying to find out all the checked rows and process accordingly.
But the issue I am getting is, I don't find the FindControl Method through which I can check whether a checkbox is checked or not. Am I missing something in the code below or is there any other way of getting the result.
I am trying to use the following code:
For i As Integer = 0 To DataGridView1.Rows.Count - 1
ch = CType(DataGridView1.Rows(i).Cells(0).FindControl("gridchkbox"), CheckBox)
Next
But VB is giving an error
"FindControl is not an member of System.Windows.Forms.DatagridviewCell"
I am sorry if it is a very naive question but any help in this matter will be highly appreciated.
I have checked many sites and many books but could not get any solution to this issue.
As I am new to VB .Net I am stuck at this position.
Thanks in advance.

I believe that you need this instead:
ch = CType(DataGridView1.Rows(i).FindControl("gridchkbox"), CheckBox)
Why is common sense not common?

Thanks Wes for the reply.
Unfortunately still I am not able to get this FindControl Method. Not sure if I am missing anything. It just declines to come in the dropdown when I give "Rows(i).".
Since I am new to .Net I don't know if it is related to any Namespace or anything of that sort which I may not have added in the Project.

suppose I have database access:
Dim Conn As ADODB.Connection
Set RS = Nothing
Set RS = New Recordset
Set Conn = New ADODB.Connection
Conn.Open ConnectionStringHere
RS.Open "SELECT Fields " & _
"FROM Table WHERE Whatever = ?"
Conn, adOpenStatic, adLockOptimistic
Datagrid.DataSource = RS
when you perform the insert, delete, add new data, datagrid refresh the data can not although I have to use appearance Datagrid.Refresh new data is entered but does not appear, check the data in have access but do not anticipate new output datagrid except close all open programs to emerging new data on the grid, the operations insert, delete, add items via the command. Execute (strSQL ), why not refresh the datagrid? and how to fix?

Why are you using VB6? It's dead, unsupported, and teaches you bad habits.
Without you supplying code to do the update, insert and delete operations on the database, none of those operations are going to happen. Nothing ever happens "automagically".

I don't know why people are still using it. Seems the poster is from Vietnam, but even then that isn't an excuse to not get VB.NET...

im not sure about the title , but i will try to explain , if you use a program like resourcehacker and check the bitmap files in C:\Windows\System32\shell32.dll there is 2 bitmap files Bitmap_633 and Bitmap_632 these 2 files are the leftside panel in the control panel features like windows firewall ,as far as i understood the Bitmap_632 is a layer to add effects to Bitmap_633 so my question is what is this technique called and if there is a tut on how to use it in vb.net would be great

There are plenty of tutorials here on CodeProject[^], and a similar search on Google will probably find lots more.

You are probably referring to alpha blending which makes bitmaps semi-transparent. In older systems each pixel in a bitmap consisted of 3 fields Red, Green and Blue. With alpha-blending a fourth field, Alpha, is added which gives the opacity of the pixel, from 0 meaning opaque to 255 meaning transparent.

I need to read and process a textfile with fixed filesize from an unc network path. The content of the file gets updated in different time intervals (from 0.5 - 10 secs). Anybody is having any idea to accomplish this task?

Plenty of ideas. What have you tried and where are you stuck?

I thought of using FileSystemWatcher to respond to file system changes but file system monitoring of remote shares is always going to be somewhat unreliable. Maybe a polling mechanism could do the job (don't know how to adapt to the different time intervals)?

True.

..check the remote file, every .5 second? What does realtime mean here? I'm guessing that it needs be refreshed within 10 seconds, given the remote folder.
Do you "need" the share? Or could you run an app on that remote computer that reads it locally (!) and then updates all connected clients?

So what? You have some other requirement other than using the Internet Protocol for Internet chatting?
