Nobody knows what you exactly want to do, so it's always needed that you understand - at least to a certain extent - the code and methods someone gives you. It would make a lot of sense to read the hints Richard gave you, instead of trying to make him do your homework.
You can loop through your worksheets - assuming here that the shop worksheets are all named something with "Shop" - like this:
Sub LoopWorksheets()
Dim ws As worksheet
For Each ws In ActiveWorkbook.Worksheets
If UCase(ws.Name) Like UCase("Shop*") Then
RADIUS ws
End If
Next
Application.Calculation = xlCalculationAutomatic
End Sub
The UCASE is needed, because the function is case sensitive (looking for "Shop" would not match your sheet "SHOP")! I would also recommend you to rename your method, because "radius" is a math function and might lead to confusion.
Your function would then consume every worksheet that your loop passes:
Sub RADIUS(ByVal sheet As worksheet)
You can also streamline your function a lot. Instead of
Worksheets("WAREHOUSE").Activate
Range("C2:d2").Select
Selection.Copy
sheet.Activate
Range("f2:g4175").PasteSpecial Operation:=xlPasteSpecialOperationAdd
you could just use one line:
sheet.Range("f2:g4175").Value = Worksheets("WAREHOUSE").Range("C2:d2").ValueThere's no need to activate every worksheet before doing something on/with it. This is only needed in certain cases, e.g. if you explicitly want to "Select" an object (sheet, range, cell etc.). Usually you just reference the range like "sheet.range(...)". For example
ActiveWorkbook.Worksheets("WAREHOUSE").Range("A1:H1").Interior.ColorIndex = 3 will paint your WAREHOUSE sheet titles red.

Hello,
I have a funny question which arises from the effects I recognize in a sample app.
At a certain point the sample app reads the files of a directory into an array. Since the path to "System32" was anyway pre-set in the sample, I realized the array gets filled with 2560 strings in the array - despite of more than 5000 files in that directory. After changing the path to another Windows directory ("System"), the array again filled with 2560 files only... No error in both cases. Then I changed the path to a different directory (holding approx. 6000 files), and the "GetFiles" array got filled with exactly the number of files existing.
I tried this several times with other directories, and it seems that everything works (i.e. reads and counts) fine as long as the path isn't a system directory. Is this behaviour normal? Or what else might be going on?
Thank you for any insights
Mick

Sounds like you're running a 32-bit application on a 64-bit OS. The File System Redirector[^] intercepts your request to access C:\Windows\System32, and redirects it to C:\Windows\SysWOW64 instead.
You can either compile your application as 64-bit; use the special SysNative alias for the System32 directory; or P/Invoke the Wow64DisableWow64FsRedirection[^] and Wow64RevertWow64FsRedirection[^] functions to disable the file system redirector for your application.

Thank you, Richard, for sharing the knowledge as well as probable solutions. It's very likely that the 32/64bit thing is the reason for the effect.
As I wrote before, it's a sample app I examined, so right now I don't need the solutions. But now I'm more prepared for that kind of possible surprises  There's still some queston marks, since SysWOW64 has only 2517 (not 2560) file entries on top-level, but it's good enough for having a first clue and some attention around that issue.
Regards
Mick

Be careful with the overloads:
string[] files = System.IO.Directory.GetFiles(@"C:\windows\system32", "*.*", SearchOption.AllDirectories); looks into sub-directories, while the simple form
string[] files = System.IO.Directory.GetFiles(@"C:\windows\system32"); does not.
I think that is the reason for the differences you experienced.
|
|
|
|

Thank you, Bernhard - that's indeed a very good point to look at. Unfortunately, right now I can't look up which overload was used in the sample... most probably I deleted it after having the code run for demonstration of its methods. But I'm going to check your hint later today.
|
|
|
|

Now, thanks to the insights of my helpers, I could make it clearer. I only checked the top-level number of files using
Directory.GetFiles(pfad, "*.*", SearchOption.TopDirectoryOnly))
Here's what I found:
• there's no redirection to "SysWOW64" once "System32" is specified as path. I can get the files of both, once set as path.
• the result 2560 was correct, but I could only verify this number after setting the system files (etc) to visible in the folder options!
• i.e. the GetFiles method counts hidden files as well (which it is supposed to do)
So in the end my question arose out of not considering that, in the Windows directory and it's subdirectories, many files are hidden and/or system files. The GetFiles method was completely ok, only my verification wasn't.
Thank you
Mick

Hi all,
I feel pretty much lost, despite (or because of?) of reading tons of material about delegates already. Maybe someone could help me understand a bit more and give me some hints?
I have
a) an MDI Form which serves as a plugin host (implements IPluginHost from b)
b) a plugin interface (defining "IPlugin" with an event named UIUpdate, "IPluginHost" and a delegate "UIUpdateDelegate")
c) a plugin (referencing IPlugin)
The plugin class holds a custom control, which works on a long lasting task in a separate thread. The custom control is not only supposed to report the progress of this task to it's own UI (which works), but to the MDI forms Interface as well. If ok, I want to see the progress bar counting up in both of the forms.
In a sample I saw that the plugins long lasting tasks method contained
DirectCast(Me.MdiParent, FrmMain).OnUpdateMe("Loading " & i.ToString, i) <----- not working
Me.OnUpdate("Loading " & i.ToString, i) <----- working
to report the progress to both UIs. This doesn't seem to work with the plugin pattern: The type "FrmMain", having an additional "onUpdateMe" Method, is unknown to the compiler, but replacing it with standard "Form" type doesn't work since this doesn't have the "onUpdateMe" Method. Considering it's a plugin, it would anyway make much more sense to learn how to address the MDI parent form without knowing its type, if that's possible.
Before I have to run around in circles for another few days, please help me out of this trap...
Thank you in advance
Mick

Hi,
I need to delete the folder C:\Windows\System32\Macromed using vbscript but I consistently get access denied no matter how my code is written. I have used an admin prompt to run the script and used psexec to get System rights but get the same access denied result.
•File Explorer - Can't delete manually without responding to request for elevated privileges. I don't want to click the Continue button because that is likely not the configuration for 99.9% of the clients that I will deploy against.
•User CMD - cannot delete folder with RD using command window
•Admin CMD - script cannot delete the folder
•System CMD (psexec) - script cannot delete the folder.
•Trying to shell out to run RD won't work either.
I thought that this could be due to files existing in subfolders but I get access denied when trying to delete just the files to empty the folder. This folder is created when Flash Player is installed but in this case, Flash Player is removed but the folder is left behind. I think it's unlikely that any of the files (4) involved are in use.
Inspecting the security settings shows me that the folder owner is System with full control and Trusted Installer also has full control. System gets an access denied message when it tries to delete the folder even though System is the owner.
How can I change the folder security so it will allow the script to delete the folder? I am using basic code seen in just about any example given for fso.DeleteFolder. I have seen a few forums that recommend using icacls.exe. I haven't tried that one yet but intend to.
Thanks,
Rob

The account the the code is running under either doesn't have permissions or the files inside the folder are in use by some running instance of Flash or a plugin in currently running browser. Those are the circumstances you get "Access Denied" under.

Do you want to delete the folder in any possible way or only with VBScript?
I had the problem that I couldn't delete a big bunch of older windows installation files and, with the help of a real 'guru', found a working solution using shell commands - it was the only working solution I found in many months. It was a matter of broken permissions. To fix really broken permissions, the best is to run these two commands one after the other (Admin Shell):
takeown /f "C:\path\to\folder" /r
icacls "C:\path\to\folder" /reset /T
The first one will give you ownership of all the files, however that might not be enough, for example if all the files have the read/write/exec permissions set to "deny". You own the files but still cannot do anything with them. In that case (which I had) run the second command, which will fix the broken permissions.
I don't know if it would work to call these functions from VBScript, maybe it's worth a try. I'm using Win7, but for Win8.1 it should work the same.

Mick

Dear Friends
i have no knowladge on networking so i really dont know how to get this work. it seams like group of classes and how can i intigrate it with my forms to try it ? pleas help me out i need it so badly  . can any one show me how to get it working ?!
if you could build it in vb and share it with me as a zip file i would be thankful. 
there are the offical examples
1. Client : Example
2. Server : Example
Thanks In Advance

You know those code samples come in both C# AND VB.NET, right?
All you do is click on the VB tab at the top of the code sample.

Dear Friend
after pasting the code in my form where should i read incoming signals and how to initiate the connection ???
all these thing i dont know how to do them.

Those examples are written into Console applications, not Windows Forms apps.
You better do it in Console applications first and learn how the code works before you try to adapt the code to work in Windows Forms.

And you think we are going to look through that unformatted code dump to try and figure out (or guess) where this error occurs?

Dim code1 As Integer
code1 = txtallocateelog.Text.ToString
You declare code1 as an Integer but then you attempt to assign a String. The same goes for a bunch of other variables there which you have declared as Integer or DateTime. Take a look at Int32.TryParse Method (String, Int32) (System)[^] and DateTime.TryParse Method (String, DateTime) (System)[^] to solve this issue (other primitive types have equivalent .TryParse(..)-methods).
Apart from that: Calling .ToString() on a property of type String is redundant:
code2 = txtvehicleElog.Text.ToString

Don't concatenate strings to form your database queries - use Parameterised queries.
For example:
cmd.CommandText =
"insert into tbElogsheet(Allocate_id,Number_plate,Depart_date,Destination,Department,Traveller,NAME,km_read_dept,km_read_arr,Departure_time,Arrival_time,Over_time,Accident) VALUES (@code1,@code2,@code3,@code4,@code5,@code6,@code7,@code8,@code9,@code10,@code11,@code12,@code13)"
cmd.Parameters.AddWithValue("@code1", code1)
cmd.Parameters.AddWithValue("@code2", code2)
cmd.Parameters.AddWithValue("@code3", code3)
cmd.Parameters.AddWithValue("@code4", code4)
cmd.Parameters.AddWithValue("@code5", code5)
cmd.Parameters.AddWithValue("@code6", code6)
cmd.Parameters.AddWithValue("@code7", code7)
cmd.Parameters.AddWithValue("@code8", code8)
cmd.Parameters.AddWithValue("@code9", code9)
cmd.Parameters.AddWithValue("@code10", code10)
cmd.Parameters.AddWithValue("@code11", code11)
cmd.Parameters.AddWithValue("@code12", code12)
cmd.Parameters.AddWithValue("@code12", code13)
cmd.ExecuteNonQuery()
This might well cure your problem.
If it does not then use the Debugger to determine which line is causing the problem and let us know.
