I'm trying to figure out if specific Windows updates are installed so I can install the correct ones.I'm currently checking the WindowsUpdates.log file that is located within the windows directory, but it's terribly unreliable.In my search to find an alternative method, I cam across this blog post. It seems like a perfect fit. Unless you take into account that this is VBScript and their querying Microsoft.Update.Session.what class in WMI that would relate to VB so I can pull the info.
I was wondering if there is a way to detect if Windows Updates are currently being installed.The reason is that I have written some software that sends my PC to hibernation if is idle for a specific amount of time, but I do not want this to happen if Windows is in the process of updating.
Problem: Current regex pattern does not filter all lines. Adding ^ to the beginning and $ to the ending of the pattern seems to break it as well. If I try it ont gives partial results using options(multiline & case insensitive). Using it in the application returns nothing at all.
1.) I dragged my detail view over to the form window to create a bindingnavigator, fields, etc.When I press save on the form, the database is temporairly saved.However, if I save my visual basic project, I lose all the changes I have made to my database.Is there a specific save command that updates the access file permanently?The default command added by dragging over the dataset does not work.
2. My database is accessed with the following string:[code]However, doesn't this mean that the database MUST be placed in that specific folder on any PC? Is there a way to simply build the database into the compile so the program automatically generates the database when installed on anyones computer?
3.) This might be fixed by fixing the previous two issues, but if I compile my program and try to install it, I get an error message "Could not download the application.The application is missing required files."
I have created a class which builds a Crystal report and displays it in a report viewer. However, without the Crystal Redistributable, the code crashes. How can I programatically detect whether the end-user has the Crystal DLL installed? The code I am required to include is:
Currently converting the infamous Windows Update VB Script examples to VB .NET so that I can have a more polished GUI for our end user's as we have to nofity them every step of the way when installing updates (so the built in WUA interaction is not viable for us).
Converting from VBS to VB .NET seems to be more troublesome then I estimated, FYI I am no a full time .NET programmer so I might be making newbie mistakes!!!
So here is the VB Script example from MSDN for searhing, downloading and installing Windows updates using VBS:
I am writing a Windows Update Client in preperation for it's use with our Windows 7 OS when we start to migrate this year from our Windows XP SP3 computers. We currently use a vbScript to control the installation of Windows Updates, we dont use the built in Windows Update client for the installation of updates as we need a little bit more control to allow for the deferral of updates being installed and more notification to the end user as to when a reboot will occur.
I want to replace the vbScript with a VB .NET executable as the presentation of information is much nicer, so I took to converting the Microsoft WUA API examples from vbScript to .NET, Following is the the vbScript Example code I am working with, at this stage of development of the application I am looking just to get a count of updates that need to be installed:
Set updateSession = CreateObject("Microsoft.Update.Session") Set updateSearcher = updateSession.CreateupdateSearcher() WScript.Echo "Searching for updates..." & vbCRLF
Ive only recently starting fiddling with Visual Basic Express and Sql Databases. Ive managed to get a database up and running, and can query information from it. I have even created a form that can add a new entry to the table im using.The first form has a ComboBox that list the PlayerNames in my table. Form2 allows you to add a new name to the table, but anything I add isnt immediately updated in Form1. I have to relaunch the program to see the new entries. Even then, these new entries dont seem to be permanent as they eventually dissappear.The code I have for Form1:
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load .................0...................................................... 00
Is there any way to determine that a system has automatic updates enabled and has the little yellow security center icon indicating that updates are available? I'd like to drop a little service on one of my servers to monitor for that condition but can't find a good resource to get started.
I know the default install path of the app and the name of the .exe file, but is there a way to see if it is actually installed? I've seen suggestions for checking registry entries, but I don't know if this app uses any or if if varies for different users on different pc's.
EDIT: I'm starting a bounty on this question. For the moment, I've moved on and am developing my application using VS2010 Pro Beta, but I'd really like it to be able to be built with express edition, since we are generally not a .net shop and even if one or two developers have VS PRO it will not be available to our entire team.
To be the accepted answer and claim the bounty, you must provide sample code and instructions that will allow a Windows Service to be installed and uninstalled using vb 2008 express edition. You don't necessarily need to start with my code (but the essentials of it are included below).
I'm wondering how I would go about creating a program that once installed was a windows toolbar. What I'm trying to do is similar to the clipboard, but I want to customize it to my own style. I work in a data entry job and many of the bills we enter have similar information that I'd like to be able to enter without repeated typing. I'd like the toolbar to be docked to the top of the screen, and have several buttons on it. Clicking a button, while having a focus in my data entry program, would paste the button's text (or the full text of what the button caption represented) into the selected field. Alternately, if focus between multiple applications is too difficult to try, then clicking the button would highlight the text and copy it to the windows clipboard, so I could then click back into my data entry program and hit ctrl-v. I dont need help on the program itself...just on how to make it as a windows toolbar, if possible.
I wrote this code to try and figure out which drive Windows is installed on - it basically starts with C and looks for the first "fixed disk" with a Windows folder.
' Start with c: and look for first fixed drive (type=3) with a windows folder Dim getInfo As System.IO.DriveInfo Dim m_start As Integer = 67 Dim m_drv As String = Chr(m_start) & ":windows" [Code] .....
We have a certain application installed on a single machine. I would like to enable/disable a button based on the existence of this application. Is there a way to check for its existence from asp.net?
the app is currently on an XP machine, but want to code for Win7 as well. VS2008 3.51. Asp.net
Do users of windows applications have to have the database application installed if your program uses databases to store information? For example, when making VB2008 programs, if I use the visual studio express database (.sdf), or maybe a MSAccess database, to store information within my visual basic program...when I deploy the application to the users, can they run the program okay even if they don't have MSAccess installed on their computer?Also, do I need to have MSAccess installed in order to write programs that use MSAccess databases?
i have installed visual studio 2010 32 bit on my new computer which have windows 7 64 bit. Everything seems ok. But now I try to learn how to draw some spheres with movement. I have tried to install openGL2 but it does not work or said that it does not fit with 64 bit, or it works only with VC.
Could any one, please, give me a short introduction to install and use open GL in vb.net 2010 installed on windows 7 64 bits ?
I have a simple windows Service developed in VS.net 2008 and VB.net. When I install the service using Installutil.exe from the command prompt it is working like a charm.
When I try to add a setup project and set the output and build and install it though it says successfully installed, it is not showing up in the services.
The event log shows that it is successfully installed. I just did check the registry, it did place the assemblies in HKEY_CURRENT_USERSoftwareMicrosoftinstallerassemblies.
But I don't understand why it is not showing up in the services listing. I refreshed and restarted.
i'm making a little app in which i need to enumerate all the windows of a specific process. i managed to do that but through enumerating all the windows in the system and then just test if it is the process i'm talking about or not by using
[Code]....
but this method seem to take a lot of unnecessary time. is there a wind32 function that can allow me to enumerate the windows of a specific process giving its handle.
I have sent out software created with VB2008 Express and everything has installed correctly on my PC which is running windows vista. But they can't get it to install, one is running XP the other Vista, they get the following errors
Windows XP
Microsoft.VisualBasic.Powerpacks.Vs Version 9.0.0.0. to be installed in the Global Assembly Cache
Windows Vista
system.windows.forms.data visualization version 3.5.0.0 be installed in the global assembley cache first
I have been trying for days now how to create a process to the user to easily create a connection to any installed data types they have installed. I have found an example right inside vb2008. I never use this because I code my own connections, but this would be real nice if I could include it or duplicate it.
I have some code designed to locate a specific process based off of its window text, gather the main handle, and then all of the child windows. However, I have run into one problem. I cannot seem to gather all the handles and their respective text. For example, when I test my program and do a handle count on the specific process, it tells me that there are more than 400 handles for this one process. How do I get the handle pointers for this process and also gather the text associated with these handles.I have included my source code for reference.
Code:Public Class Form1 Const GW_CHILD As Integer = 5 Const GW_HWNDNEXT As Integer = 2 Const WM_GETTEXT As Integer = &HD Const WM_GETTEXTLENGTH As Integer = &HE Const BM_SETSTATE As Integer = &HF3 Const WM_LBUTTONUP As Integer = &H202 Const WM_LBUTTONDOWN As Integer = &H201

Which is the easiest way I could get the file details / properties under windows? I am not talking about common properties (such as file size, creation date), but the ones written by variuos software. In my particular case I need to get the detail called "Date taken" for a jpg image file.
I could use PHP,Java or VB.NET, whatever is easier.My final goal: I have a bunch of images I took with different versions of Android on my phone. They are all named with different naming convention, most of them just something like IMG_[consecutive_numbers].jpg. So I want to rename them all, but for that I need their original creation date, and since I have moved them from my pc to the phone and back so many times, I cannot trust the "creation date" property. I found that all of them have a property which was set by the camera called "Date taken", which is still intact and valid.
Is it possible to shut down windows say if the time is around 6:00 pm using the VB.net code. has any one done that. I have the code to kill my program when it is after say 6:00 pm, I would like to shut down windows along with it. I can post the code for killing my program (actually I got it from here) if anyone wants it.
I am very new to vb.net. I need to be able to see when a certain popup window appears in another application. The time time it takes to appear varies so I need to know when it appears and in some cases when it has closed.
