Error executing batch file in excel VBA windows - vba

I was trying to execute a batch file via standard call shell() function.
This Batch file is project specific and created automatically for each project by an external application. Main function is to normalise around 40 files having statistical data used for my project. This data is being acquired form excel. While executing manually this takes around 30 seconds for the complete process and its working just fine.
When I try to access this using call shell function in VBA, It just pop up for like 2 seconds and outputs were not generated from Batch file.
I am attaching My sample code below used for this. I am just baby-stepping in VBA Macros. Please Excuse my coding practice.
Call Shell(Range("L8") & "\DSTAT$.BAT")
I tried this also
`Dim Runcc
Runcc = Shell(Range("L8") & "\DSTAT$.BAT", 1)`
Please let me know if any further information is required to sort this out.

Try
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1
With CreateObject("WScript.Shell")
.Run Range("L8") & "\DSTAT$.BAT", windowStyle, waitOnReturn
End With
I use this for converting PDFs to JPG with Irfanview on report_open in Ms-Access.

How to call java object in VBA with classpath

We use a CMD to call a PowerShell script. In the PowerShell script, a Java program is called. Both files are in the same directory. I want this all replaced by VBA within Microsoft Access. I have found several related topics but I can't decide whether it is possible or not based on these topics. Topics like Launch jar file from VBA code
The CMD contains the following code:
SET CLASSPATH=.\yyyyy.jar
powershell .\startscript.ps1
The PowerShell script contains the following sample:
& java '-Djavax.net.ssl.trustStore="zzzz.keystore"' com.router.router.router.Router -user:... etc.
We also run the same Java program in a different setting, only with the use of one .CMD-file. This is made like:
SET USR=user
SET CLASSPATH=.\yyyyy.jar
java -Djavax.net.ssl.trustStore=zzzz.keystore com.router.router.router.Router -user:%USR% etc.
Preferably both PowerShell and CMD become obsolete and the parameters like "-user" are fed with variables from the VBA code.
Does someone have a usable link, example or code? Please advice.
What you are trying to do is to run a command via the command line. It just happens that this command runs java, as far as the VBA code is concerned it may run anything that the shell would understand.
A sample code to run a command via a shell in VBA is the following (note there are many ways and it's super easy to find these samples on internet, I'm just using the first one I found):
Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = False
Dim windowStyle As Integer: windowStyle = 1
wsh.Run "cmd.exe /S /C " & yourCommand
... where yourCommand is the litteral string you would run in your command prompt. Now, it's all about string concatenation in VBA. Following your sample (and adding the username directly from VBA):
user = Environ("UserName")
yourCommand = "java -Djavax.net.ssl.trustStore=zzzz.keystore com.router.router.router.Router -user:" & user
(please note that I replaced %USR% - which asks the shell to retrieve the username - with a variable user that I've defined in VBA, even though in this specific example, the function Environ is asking environment variables so it's still asking it to a shell).

Call .reg File from Excel-VBA script

I want to call a .reg File out of my VBA script. I'm using Office/Excel 2013.
I know Excel can't run these files by itself, so i need to call the file via shell. The code i wrote doesn't work:
Sub deactivateHyperlinkWarnings()
Dim x
x = Shell("cmd /C C:\TEMP\DisableHyperlinkWarnings.reg")
End Sub
I found this piece of code somewhere on the web, but its not working. I don't even get an error message. The .reg File is located in C:\TEMP
What do i need to write to make it work?
Plus: Is it possible to suppress the MessageBoxes that are displayed when i run the .reg-File? When i start the file manually, i need to Hit "OK" like 3 Times. The people who are working with the Excelsheet later on shouldn't be seeing these things.
Instead of running cmd try to run reg. So in your case it should be x = Shell("reg import C:\TEMP\DisableHyperlinkWarnings.reg")

multiple programming try to access same text file

I had created and text file using (AFL SCRIPTING LANGUAGE) this script will update (write) to a text file every 5 seconds. I will try to read file using vb.net, when I run the vb.net code form visual studio, everything works fine but (AFL script not able to update the text file), here is my vb.net code:
Dim FILE_NAME As New FileStream("C:\myreport\myfile.TXT", FileMode.Open, FileAccess.Read, FileShare.Read)
REM Dim FILE_NAME As String = "C:\myreport\myfile.TXT"
REM Dim TextLine As String
REM If System.IO.File.Exists(FILE_NAME) = True Then
Dim objReader As New System.IO.StreamReader(FILE_NAME)
Do While objReader.Peek() <> -1
MYSTRING(I) = objReader.ReadLine()
I = I + 1
Loop
REM End If
When I run the code above, ( AFL script not able to update the text file),
Put simply:
When I run the vb.net code (for accessing the text file), AFL script not able to update.
I had share read/write the folder (where the text file exists), no effect, same problem I am facing.
Unchecked "Enable visual studio hosting process", still problem not solved.
In .NET, the FileSystemWatcher class can help you with this problem. You can read the file each time the file watcher says that the files has changed. Here is the reference documentation for it.
You cannot read and write to a file from two processes at the same time. Well, technically you can, but it can lead to a race condition which is bad.
You need to implement some kind of shared locking mechanism around the file to prevent your two programs from fighting over it. Or, if you can guarantee that the consumer VB.NET program will have the file open for less than 5 seconds, you can go with MrAxel's solution and simply have the VB.NET program read the file every time it is updated.

Getting shell cmd output to Excel

I have a macro in VBA (Excel 2007).
It opens an exe file with entering a HEX value as variable.
The exe gives the output (also a HEX number).
I do everything with "shell" command and the results is saved to a txt file. Then I write this to Excel.
retVal = Shell("cmd.exe /c C:\AABB\app.exe 0x5110 > C:\AABB\output.txt", vbNormalFocus)
It is complicated and time-consuming.
I would prefer getting the result directly to Excel, without an intermediate file like txt or similar.
When I use an output.xlsx as output destination, the file is created and the value is written. But I cant read it with Excel. I see the value when I open the xlsx with Notepad.
My questions are:
1) Is it possible to write the result directly to xlsx, especially a target cell e.g. A10
2) Why when I use xlsx as destination in shell command, I can't open it with Excel? It gives Error Message of "file-format or file-extension is not valid. Data might be corrupted".
I think you can't do that with shell object.
you can do it with WSHExec with the function StdOut.ReadLine().
You have to go to reference and choose "Windows Script Host object model" so you can declare a WshExec object. than see the Method yourWshExecObject.StdOut.ReadLine().
To construct WshExec :
First declare a WshShell Object and you construct it like that :
Dim WshShellObject as WshShell
Dim WshExecObject as WshExec
Set WshShellObject = New WshShell
Set WshExecObject = WshShellObject.Exec("your .exe filename").
The WshExecObject.StdOut TextStream will read everything you write in the console.
I did it with an .exe compilated with C++.
You can also use WshExecObject.StdOut.ReadAll to read all lines at once.
Hope that helps.

How can I use VB.NET to execute a batch file on another computer?

In vb.net 2008 I want to execute a batch file that resides on another computer.
There is no error, but nothing happens.
Here is the code:
Dim pStart As New System.Diagnostics.Process
Dim startInfo As New System.Diagnostics.ProcessStartInfo(serverpath & "\file.bat")
startInfo.RedirectStandardOutput = True
startInfo.WindowStyle = ProcessWindowStyle.Hidden
startInfo.UseShellExecute = False
pStart = System.Diagnostics.Process.Start(startInfo)
pStart.WaitForExit()
pStart.Close()
To run a process on a remote computer you can use Sysinternals free psexec.
You can call it with the proper parameters and having the required permissions like you are doing in your sample code.
I've never tried to create a Process using a batch file as the executable. I've always had to use cmd.exe as the program. This has worked for me in the past:
Dim startInfo As New System.Diagnostics.ProcessStartInfo("cmd.exe", "/c " & serverpath & "\file.bat")
The "/c" as part of the argument list tells cmd.exe to exit after the batch file has completed.
If you are going to use RedirectStandardOutput, you really do want to use RedirectStandardError, and then also subscribe to the events of the Process class for catching data on those streams (OutputDataReceived and ErrorDataReceived). Otherwise you will have no way to debug your batch script.
This reads like a permissions problem. I would troubleshoot it that way if you haven't ruled it out yet.
Have you tried running the same batch file from the local computer?
If it is a permissions issue you can solve it either copying the file locally before executing it or map a drive to the remote computer where the file is and then execute the batch file from the new path.
Additionally, we don't really know what's in the batch file that could be causing an issue. I would either post the batch file or if you can't post the batch file use a batch file that you can post. Example a batch file would write the current date time to a file.
