Hi,

I am able to work it out with FileSystemObject as below but the same code I want to write with Windows API, can anybody please help me in sorting out this problem.

Dim fso As New FileSystemObject
Dim fold1 As Folder
If Not (fso.FolderExists("C:\Fold1")) Then
    fold1 = fso.CreateFolder("C:\Fold1")
End If

Thanks,
Aleem Mohammad.

From the cycle "writing your code in 24 hours from scratches". Seriously take the time and read a few resources yourself rather than asking everything on forums. Not to mention the fact that if you dun really understand what's going on in the copied code you will be unable to debug it if something occurs. Then probably we'll get a new round of "questions".

You're not disturbing us. We're just pointing out that your overcomplicating your code and your going to run into too many walls that you don't need to run into.

You don't need the Windows API to do this. It's not going to give you a performance benefit. You're creating a directory on a drive, not calculating PI to 1,000,000 digits.

Keep your code simple and easy to maintain. Use the FileSystemObject to do this. If you do this with the Windows API, you're going to get lost, very, VERY quickly and write about 50 times the code you need to write to do this little job.

try this

use files to trasfer data between your textboxes.

write content of textbox1 text to a temporary file, read it from second thread and put it in the second textbox2.

Well, while that is possible to do so, it is not very efficient.

Close an excel opened in AxWebBrowser

You cannot access controls from threads other than the one that created the control. It's also a really bad idea to create controls on anything other than the UI thread (the one the application started on).

I am opening an existing Excl sheet in a AxWebBrowser (that's the easiest way i got) on a window form created by VB.net 2005.

My issue is that i am not able to : close the file so when i try to open another file or over write the same file (on HDD) i am not able to do it.

Also i find the excel exe (in the task manager) running in the back which is not freeing the excel.

What can be done to solve these issues?

that is exactly what i do not know how to do? Any idea apart from killing excel.

try this
just kill the excel process from the task manager, from your application.

use this below code.

Public Sub Kill_Application(ByVal ApplicationName As String)
Try
Try
Dim processList1() As Process
processList1 = Process.GetProcessesByName(ApplicationName)
For Each proc As Process In processList1
proc.Kill()
Next
Catch
End Try
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub

Thanks a lot, it works

the only issue with this is it will close all the instances of excel, which means if the user is working on any Excel sheet apart from our application it will also get closed. Is there a way out?

below code will help u

first get your application process id into a global variable.
then kill that particular process only.if it is have another instance.

Private Sub testingkill()
Dim procid As Integer
procid = Shell("calc", AppWinStyle.NormalFocus) ' Activate the Calculator application.
Try
Try
Dim processList1() As Process
processList1 = Process.GetProcesses
For Each proc As Process In processList1
If proc.Id = procid Then
proc.Kill()
Exit Sub
End If
Next
Catch
End Try
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
