Waiting For A Shelled Process To Finish Before Continuing With Application?

Mar 7, 2011

I'm currently making a Computer Cleaner, my program launch's rundll32.exe's to clean IE's history.

Like to clear the add-on settings I would put:

Shell("RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 4351")

But I need to wait for it to wait before letting it to go on to the next thing like clear cookies, which would be: Shell("RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 2")

VS 2010 Waiting For A Screen Re-draw To Finish Before Continuing?

Oct 16, 2011

I'm writing a simple program that takes a screenshot of tab1 of the GUI, then takes a screenshot of tab2, then tab3, etc. I've got the screenshot code down pat, but the problem with my current code is that it's taking the screenshot of each tab before the screen has a chance to fully redraw, so the resulting images are screwed up.Is there a way to get the program to wait for each tab (and all the controls in it) to be fully visible before each screenshot is taken?I'd like to avoid using a timer for this, as the screen redraw speed will vary depending on the user's computer, and the contents of each tab, etc.[code]

Waiting For A Thread To Finish?

Mar 11, 2009

I am trying to make a marquee progress bar run while my long function is running. When the function is done running, I want the progress bar to disappear.

[code]...

If I don't do t.Join(), the progress bar disappears right away and then the thread runs. If I do Join(), the progress bar doesn't appear until the message box pops up after the thread is done!How would I get the effect of the progress bar running while the thread is running and then stopping when it's done?

VS 2008 : Blocking In DoWork() While Waiting For Another Thread To Finish?

May 6, 2009

In my DoWork() function I register with our sip server. Then I have to wait for a response back. However, the response I get is received in another event. However, before I am able to check the flag in the DoWork() the DoWork() has all ready finished and the response comes after.

I am trying to find a way to wait in the DoWork() until I get a response in the Diagnotic event. I have a global flag that is set in that event that I have to check in the DoWork().I was thinking of maybe blocking in the DoWork() until the other event is finished. Maybe using a join.

' Do work in background worker
'Will return less than 8 if there are no error message from the library
If (Not Me.bgwProcessLogin.CancellationPending) Then
' Register and wait for response

Waiting For Webbrowser Control To Finish Loading Page?

Dec 25, 2011

I have been tasked to do a project, and have been given a list of links from the client - what the Project needs to do is:1 - open google with a specific search phrase - no problem2 - look on that page for any links containing any member of the list of links, if found, invalidate the entry in the list, and auto-click the link, then go back3 - repeat for any other "finds" on that page4 - when done, auto-click on "Next" (no problem) and go back to step 2For now, I am not even attempting to auto-click the found link and go back, I am just listing all found links in a TextBox. The problem I am having is waiting for the next pages to load before looking for a match in the list of links. I tried using webBrowser.DocumentCompletedto set a Boolean - I tried testing WebBrowserReadyState in the DocumentCompleted event ar the code below gives the best results but it is inconsistent, meaning it completely misses some pages that I know have links on them that match.

VS 2008 Getting 32/64 Bit Info For Shelled Process?

Oct 30, 2009

So I transitioned over to Win 7 64 bit, and am starting to incorporate it into my program. I understand that My.System.FileSystem.SpecialFolders.ProgramFiles will resort to x:Program Files if the host system is 64 or 32 bit. However, if the host is 64, and the program is 32 bit, one would need to acess x:Program Files (x86).

My question is this:How can I test an executable to see if it is 32/64 bit, and then apply the proper program folder?

Jun 29, 2011

I have seen people use the code

Do Until WebBrowser1.IsBusy = False
Application.DoEvents()
Loop

or use the WebBrowserReadyState however, this doesnt seem to work after I invoke a member For example, I use "invokemember("click")" and then after that, use the WebBrowser.IsBusy or ReadyState, and do another InvokeMember, it doesnt work. It seems after I invoke a button and it navigates, it doesnt seem to matter?

Waiting For Process To Start?

May 5, 2009

I have a problem with an App I am writing that lists information about various media on your computer and lets you launch it right from the app. My problem is, when launching an intensive process, like a game for instance, it is desirable to shut down the app to not hog precious resources. Here is the code i have so far...

[Code]...

This code works fine, but for one small detail. The app exits before the desired process starts, thus cancelling out the process all together. My question is, how do I get the app to wait for the process to start before exiting?

.net - Closing Main Form Doesn't Finish Process In Windows 7?

Feb 23, 2011

I have an MDI form as the app start object.I don't think is related, but in the Form closing event, I check for some condition, and if it's true, I ask for confirmation before closing:

Private Sub FormBackground_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
If (e.CloseReason = CloseReason.UserClosing) Then[code].....

So long, everything works fine in my development machine, which runs windows XP.However, when deploying the application in a windows 7 machine, the message box works correctly, showing itself whenever it should, but after the form is closed the application keeps running in the background. This happens whether the form closes directly or asks the user first.I have fixed it putting an End instruction in the FormBackground.FormClosed event, but it doesn't feel good.

Vb Write To Text Box While Application Is Still Waiting For HTTP Request

Jan 23, 2012

I have a form in VS2010, written in VB, and it has a subroutine calling for information out on the web using an httpwebrequest object. It takes a while for the response, and I would like the subroutine to write a message to the form (into a Label) for the user to see while waiting for the application to respond.

I tried writing the message with a Backgroundworker and then as a second thread. I got it to write the message, but it always seems to wait for the http response before writing the text. How do I write the text immediately, while waiting for the data?

Hook Excel - The Process Excel.exe Doesn't Finish After Close Excel

Jul 20, 2010

I need to access the current instance of MS Excel. To do that, I wrote the following code:

Imports Excel = Microsoft.Office.Interop.Excel
Imports System.Diagnostics
Private _ExcelApp As Excel.Application

[Code].....

The code runs nice, but it has a problem: After the user close the Excel application (click button X - note: no other instance of Excel exists), if you open the Windows's task manager, its possible to see the process Excel.exe.

If I open and close the Excel application, there is no process Excel.exe, but if I run my code with the Excel application openned, after the user close the Excel application, the process Excel.exe isn't finished.

File Copied With FileInfo Not Able To Be Read By Shelled Program?

Jul 3, 2011

2 - Saves the server XML file it into a folder separate from the root folder of the application.3 - Deletes the local XML file in the root folder of the application.4 - Copies the server XML file to the local folder of the application.5 - Opens the application.6 - Closes the updater.Now when the application opens, it reads this XML file in the local folder. When I run it stand alone, it works fine and can find this XML file. However, my problem is when the application is opened by the updater, it can't read the XML file in the local folder. I check for this file doing File.Exists(XMLfilename) and it returns false but like I said, if I close the application and reopen it it works fine.

I'm thinking that for some reason the updater is "locking" this file so my other process can't read it? I can't close the process before I open the original application so I'm not sure what's happening here. My Update Folder is the users ApplicationData folder and the root directory of the application is in the Program Files folder.

This is my code in the updater:
Dim ImageDir As DirectoryInfo
Dim fi As FileInfo

Add Item To ListView While Continuing Other Code?

Jan 22, 2011

I have coded a low-level mouse hook. Each time the user clicks (let's say) the left mouse button, a custom event gets fired which is then handled by a form in my application. On the form is a ListView control with the following columns: Time - Application - Button.

I want that ListView to contain the last 1000 mouseclicks made, so each time the CustomMouseClickEvent gets fired, I check for the itemcount of the ListView, I add an item to the ListView and I resize all three columns. Problem is however that this extremely delays the processing of the mouseclick messages.

I'm wondering if it's possible to raise the CustomMouseClickEvent and then handle it in my application while at the same time the mouseclick message is passed on to the next hook to get processed by the systen?

I have something like this:

For Each Entry In CheckedListBox1.CheckedItems

Form2.Show()

But that just froze everything and used up all my CPU.
