If you start an exe file by using a Process, you can set certain ProcessStartInfo parameters beforehand, such as CreateNoWindow = True (to hide the process), as in this example:
Dim myExe As New Process
Dim p As New System.Diagnostics.ProcessStartInfo
p.FileName = "cmd.exe" 'starts the cmd console

I have a tab control which contains other controls which I populate at run-time. I want to be able to hide certains tabs in this control and then make them visible at certain times. My understanding is that you cannot hid individual tabs in a tab control. All you can do is add them and delete them. If this is the case, is it possible to populate my controls in a Master TabControl at run time, then use a second tab control which is shown at the end of the routine, then add/delete tabs to this second tabcontrol and copy the populated controls from the Master TabControl to these tabs.
The idea being that I will create my tabs on the fly after the routine has run but I need the ability to copy populated controls held elsewhere into this tabcontrol.
I have been working on a program to hide windows for an active process. I found some examples on the internet explaining how to do this. The problem, however, is that after I hide the windows I cannot get them back. The process still shows up in task manager but i cannot restore the window..
Imports System.Runtime.InteropServices
Imports System.Diagnostics
Public Class Form1

So i want to start an application with my vb.net app and it should start as a hidden process, meaning no window and nothing in the task bar, only in the task manager ofcourse.
This is what i do
Dim fov As New Process
If CheckBox2.Checked = True Then
RichTextBox1.Text = RichTextBox1.Text & vbCrLf & "* - Launching"
fov.StartInfo.FileName = ("test.exe")
[Code]...
This does not work.. I have also tried the "fov.StartInfo.CreateNoWindow = True" command which does not work either. I can live with a solution that would start the window minimized instead of totally hidden.
Ok, so I'm using vb.net and there isn't a way to unhide/hide tabs so I have to use TabControl.TabPages.Add() and TabControl.TabPages.Remove() to do this. All of my tabs are labeled as Account1, Account2, etc. all the way up to Account25. I want to make a loop and be able do something like this so that I can add the tabs in the right order:
View 2 RepliesI have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).

It seems to work 90% of the time. However, sometimes the PID.Kill() fails because it says the process already exited. At this point the OSK is always still there on screen. Yes, I know my code should be testing to see if the process is still running before trying to kill it, but given that the OSK is still on screen..
I have a program that starts another program after setting the regkeys basically the program continually syncs the calandar of outlook and another application.I set the regkeys than launch the c:sync.exe app. I have tried a simple process.start and launching the process as a thread and they both do the same thing: The other process starts and works as it should but my main program goes "White screen" or "not responding" until the process.start has exited.
I want the process.start to run in the background so if users click in my main app it responds and truly that they can access the context menu of my main app from the taskbar while the process.start is running.

View 9 RepliesI am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")

I have an issue using Process.MainWindowTitle,Process.MainWindowHandle on some older VB6 applications. After Process.Start I use Process.MainWindowTitle to display in a listbox. The MainWindowTitle returned is not the Window Title but in fact the Project name of the VB6 exe.? I also store the MainWindowHandle to use the ShowWindow and SetForeGroundWindow API's. It would appear that the ShowWindow API does not work, but the SetForegroundWindow does. ie: if the VB6 app is minimized, showwindow does not restore, if it is NOT minimized setforewgroundwindow sets it to the foreground. The exact same code does work correctly for any other .net exe or notepad, only on these vb6 programs I am having a problem.

(I know there are lots out there but I can't find this one tweak)The following code runs well enough, I just need to be able to run a loop that says if a given row in the datagridview is .visible = false than I need the corresponding row in the excel spread sheet to become hidden.[code]
View 5 RepliesI have a datagridview and once I populate the view with the data source I hide the columns that I do not need. For some reason the 1st column is not hiding. I have checked the column name and they match and the 2nd line executes fine hides the column for the EVENTID. I even did a messagebox.show( dgvTourOther.Columns("OTHERID").name) and it returned the correct name.
dgvTourOther.Columns("OTHERID").Visible = False
dgvTourOther.Columns("EVENTID").Visible = False
The values being passed are all strings. I do this on 3 other datagridviews ok but for somereason this gridview is acting different. I am going to try an rearrange the columns and see if that helps.

Say I have Combobox1 with items (1)Breakfast (2) Lunch (3)Dinner
and I have combobox2 with items (1)Apples (2)Bananas (3)Grapes(4)Oranges
Now when I choose Breakfast in combobox1, I want user to see all 4 items in combobox2. But when I choose Lunch in combobox1, I only want user to see (1)Bananas(2)Grapes(4)Oranges in combobox2, hiding Apples.
Does anyone know a code where I can hide an item in a combo box depending on the condition?
I was just googleing this, and i came across this

p.StartInfo.UseShellExecute = True
p.StartInfo.FileName = "cmd.exe"
p.Start()
Does that mean that i could show it again? if so, is there a code that can do this?Also, if i wanted to get the window that the user is currently in, how would i be able to hide that?
