Load Events Not Starting When Running As Another User?
Feb 15, 2012
I've created an application that is supposed to map a network drive as soon as it starts using this basic sub:
Private Sub DesktopAssistant_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'ElevatePrivileges()
'System.Diagnostics.Process.Start("batch\mapfs.bat")
[code]....
Here is the code for the MapDrive function:
Imports System.Runtime.InteropServices
Module map_unmapdrive
Public Declare Function WNetAddConnection2 Lib "mpr.dll" Alias "WNetAddConnection2A" _
(ByRef lpNetResource As NETRESOURCE, ByVal lpPassword As String, _
[code]....
It works perfectly fine when I start the application, but when I do RunAs and start the application as another user, the MapDrive function does not seem to execute. Everything else in the application works when running as another user, just not on-load events.

i am a casual user of visual basic express 2008 and use Vista Home Edition Ive been using it for a while now, with no problems at all. Recently i started to take a look a WPF in my apps, again no problems.(visual basic express ran fine, debugging ran fine & finished apps ran fine)
However for some reason (and all of a sudden) i keep getting errors and none of my apps will start up.
The errors are:vshost.exe has stopped working (I get this when visual basic express starts)PresentationFontCache.exe has stopped working (I get this when visual basic express starts a wpf app)
(Application Name) has stopped working (I get this when running finnished apps)I've tried all the usual methods (Reninstalled VBE & .Net3.5)I cant see why it has stopped working all of a sudden?

My app (which runs ok as a standard user) requires updates to be installed, but I don't want to have to input the administrator username/password each time nor do I want to increase user privileges to administrator.
I have a windows service which handles the downloading of updates etc (running as Local System) but the start command needs to come from the main app (running as a standard user). This is not permitted and I get Access Denied.
I understand why this is happening but is there an alternative way to achieve this? I want to handle program updates as the standard user without using ClickOnce or installing to a non Program Files folder.

I'm trying to automate a product that provides no such automation capability.I've take a cursory look at loading the app in a separate AppDomain, and also, through reflection, executing the Program.Main() to get the app running. I also tried getting the windowhandle from a separately created Process object (which I've learned will not work).If I have a reference to their assembly added to my project so I can reference an instance of "TheirProduct.FormMain", what, if it's possible, is the best way to go about capturing events from that form? What I need to do is to be able to capture a couple events, and perform a few Button.PerformClick() against the form.

I created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at. I want to use this control kind of like an animated icon within a application, but because the picture box is docked, the control I created won't respond to the events, MouseHover specifically.

I'm running an application under an account that is not the account logged-on to the PC.
Within the application I need check if the logged-on user is a member of the Administrators group. Below is the code I'm using. From what I've read, WindowsIdentity.GetCurrent() should return an object associated with the logged-on user. It doesn't, it returns the same information as the call to System.Threading.Thread.CurrentPrincipal. Which is the information associated to the ID running the application, not the logged-on user.

I found this mystifying in VB6 and it's still here...
For example - I have a combobox on a form and I have put some code in its SelectedIndexChanged event. The problem is that I want this code to be executed *only* when the user clicks on an item in the combobox dropdown. Why is it then that it gets executed when the form first loads? And how do I stop this happening?
I used to use a "FormLoading" boolean to decide whether or not the code was executed but this surely shouldn't be necessary. Is there a better way?

Here's the situation: I have a variable number of dynamically created update panels on my page, so I thought I would write one method which handles all of the loading for each one.
My Updatepanel creation looks something like this:
Dim newUpdp As New UpdatePanel
newUpdatep.ChildrenAsTriggers = False

Load , Initialize , Activate . What's the difference among them ? Up to now I was used to the classic VB6 events , but it seems that in .NET they are different . I was used to these ones :Load / Initialize : both the first step before showing a form . One appeared in VB6 , the other in VBA .Activate : triggered when a form is selected .However I thing that now , not only they differ , but they also come in a different order ...

We have a purchased application written in Visual Studio 2005 that uses tab controls for displaying information. One of the tabs is for reporting and I am trying to run some code to enable and disable a Validate button. It has a proprietary report component (LxReportView1) that is initially disabled. As user enters information, the Validate button is used to check for required fields. After data entry entries have been validated, user click Validate one last time and record gets flagged as validated and report component (LxReportView1) gets enabled for use. Ideally, whenever this Report tab is clicked, it will run my code EACH TIME.[code]Works fine when user's first action is to bring up a record that has already been validated. So when user clicks on Report tab, report component LxReportView1 has been enabled for use and the Validate button has been disable just as designed. Problem is that given a list of records, if user selects a record that has NOT been validated yet and then later on brings up another record that has been validated, code does not run. How can I get this code to run EACH and EVERY TIME the form loads.

I have two forms. On form one, I have a serious of check boxes and in form two I have functions relating to those checkboxes. When the second form loads, I check the Checked State of the Check Boxes, and run the appropriate functions. This is working just fine. The problem I have, is that the second form doesn't show until the functions that have been selected have completed. It would be ideal if the form would load and then run the functions.
I don't think that I could have everything run on startup, but hopefully there is another method. I know I could load the second form and then just run the code in the previous form, but this is less than ideal, because I can't show the second form as .ShowDialog and I want to be able to split up the code into the other form so that it's not so crowded and easier to read on the first one.

I'm using VB10. Can someone explain why you would use user events instead of just calling a sub or function? Isn't user events the same thing a sub's or function's?

Now what i require is i want to disable some events of Windows.forms.Label to User of that UserControl (Name is LinkLable).
i.e. Label has an Event onPaint. now if some user invokes LinkLable to his form he must not be able to write a code for LinkLable.

I made a custom control for my form. It's basically a custom button I made using a label.The only problem is, when I apply a myButton_Click event to the control in my main form, it will only be triggered if the control itself is clicked. The label takes up the entire form (it's docked inside it). The click event isn't triggered when the control (virtually the label) is clicked. You must click behind the label (the form's background) for the event to be triggered. How can I pass the myButton_Click event to the label so it is triggered when the label is clicked? I hope I'm making sense.

I have recently created an application where a lot of data is loaded into objects when the application starts up, and other data as it is required. For example if the user requests the catalogue page then it will load all the top level category data into objects of type Category. This will then stay there to be used by other users (who will therefore not have to load this data into objects) and can be altered by admin if they happen to login during the same application instance. I know this is not the most efficient solution, as pointed out below, but it works and the page load, at the moment, is not too long. It is very quick if most of the required data is already loaded into objects. It is also tailored to the business' needs - unlike other techniques such as Linq-to-SQL.

I have a few subs that run under Webbrowser1.document completed section of my app I know the code words because I tried it out using a new project and tied the code to a button and it works great. After stepping into my code during run time it appears that the app is trying to call my sub before the next page appears. What would be the way to place a pause on the Thread so that the web page can catch up before running the next sub?

I like to build objects that contain properties and also functions / subs to do work. I dont have a lot of other programmers around me to answer this question so I thought id ask. If my goal is to make a function or even sub part of a class blue print is it better to do it by making a seperate class for the function, and then construct a new copy of the classFunction as a property of the parent class or is it better to simply put the function in the parent class.

In order to take advantage of the spell checking ability of WPF textboxes, I have added one to a user control (with the use of elementhost). This user control is used in various window forms. My current problem is trying to handle keyup events from this textbox but the windows form is unable to "get" any event from the control. I can access the properties of the textbox just fine (i.e. text, length, etc.) but keyboard events don't seem to work.I have found, however, that the following will bring back events from the WPF textbox:
Public Class MyUserControl
Private _elementHost As New ElementHost
Private _wpfTextbox As New System.Windows.Controls.Textbox
[code].....
The user control is now able to do something after the PreviewKeyUp event is fired in the WPF textbox. Now, I'm not completely sure how to have the window form containing this user control to work with this.
