Detecting A Message Box Opened In Another Application?
Jun 2, 2010
I am developing a windows service, in vb .et, that launches a legacy application that performs some work. The service acts as a wrapper around the legacy app allowing users to automate an otherwise manual operation.Everything is working great, except occasionally the legacy app displays a messagebox. When it does this the process halts until the message box is closed.
As the service will be running on a server there will be no user to close the message box.The service launches the legacy application in a System.Diagnostics.Process.My question is, is there way to detect that a message box has been displayed by a process that I have started using System.Diagnostics.Process and is there a way to through code to close the messagebox.

The following solution should allow the user to enter 'colors' to a combo box; however, if the color is already entered (in an upper, lower case or mixed case format), then the 'Duplicate Color' message should be displayed. I get the message, but my color is also being converted to an upper case format in the combo box.

Firstly I apologize as my question may seems repeated to you. But I am sure the details will not. I am writing a VBScript in VB.Net to automate some operation in SAP. The script is recorded from SAP. All I need to do is to put this script under a button click event on vb.net. I have done this far. But get stuck at one point. While doing the execution of the script, SAP displays a Message Box with two button labeled "Redetermine" & "Cancel" and I have to Click on "Redetermine" button to make the script run further.
The number of appearance of this message box is not fixed. Some times it appears twice and some times more than twice. My question is "How can I detect the Message Box from my VB.Net application and automatically click on the "Redetermine" button if the message box appears"?

When I open Microsoft Visual Basic 2010 Express, the following message comes up:
Quote: Microsoft Visual Basic 2010 Express. The automatically saved settings file 'visual studio 2010settingsvb expressCurrentSettings.vssettings' cannot be found. You can change this file on the 'Import and Export Settings' Tools Options page. The IDE will use your most recent settings for this session.
I click the 'OK' button, and the Start Page loads with the "Recent Projects" list on the left.
When I click on any of the projects to open them, another message comes up saying:
Quote: Microsoft Visual Basic 2010 Express. "Project Name" could not be opened. Do you want to remove the reference(s) to it from the Recent list(s)?
I read about a potential solution going to "%programfiles%Microsoft Visual Studio 10.0Common7IDE" but I'm not sure how to proceed. Does anyone know why this problem is occuring? Did I truly lose all my projects?

I 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've got an application which I want to only have 1 open.How would I make it check if the application is already open and only open if it isn't? I've had the idea of using 2 forms, one of which is the proper application and the other which just checks if its running then opens the other form.I would imagine it would check if there's more than 1 of the process name running and if there is close all others?

I have created a windows application which creates a database file and saves it to disk, it uses a custom file extension so that when the file is clicked it opens the application. In order for the application to use the data in the file it needs to rename the file so that it has a .mdb extension. My problem is that I cannot see how to get the name of the file which opens the application.

I typically prompt the user to save changes in the FormClosing event in MDI children. The application updater uses a Process.CloseMainWindow call to close the application if it's running before the patch update is applied.
I need to detect when the updater is closing the application and NOT prompt the user to save changes but save them automatically. I've tried using the System.Windows.Forms.CloseReason but this method isn't working for me. I capture the CloseReason in the MDI Parent FormClosing event but it's called AFTER the MDI children are told to close. I tried capturing the CloseReason (e.CloseReason) in the MDI child's FormClosing event but it registers as MDI Parent closing and a normal application exit is also going to raise this same e.CloseReason so I can't auto-save here either.
So my question is: How can I detect this Process.CloseMainWindow being used to close my application so that I can bypass all save prompts and save automatically? What is the first event called in this method of closing so that I can signal all MDI children that are open in their FormClosing event to just save?

I was just wondering - is it possible to detect, with either .net, SilverLight, Flash or some other plugin, whether or not Snipping Tool is open, or detect when the user opens it (after the page has loaded)? Also is it possible to detect when print screen is pressed even if another window is active?

I am trying to get the file path that opened my application. So if I opened my application by making the text file open with my application, how could I get the file path of that text file? Lets put it this way, you have a text file. Ex: MyFile.txt, so when you click that it opens in NotePad and loads the text in MyFile.txt. How can I do that but just get the file path?

I am a beginner using 2008 Express and I am trying to get my application to remember and restore some combobox values. It seems to work fine if the application is opened and closed normally but for some reason it loses the settings if it is opened from the startup folder.
Here is how the startup link is formed:
Dim shortcutFile As String = Environment.GetFolderPath(Environment.SpecialFolder.Startup) & "FBNav.lnk"

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.

The fact is I'm making an application, which users can install by using a Setup file...once installed the data in the database can be updated by a centralized server. To do this, they can insert a DVD/CD-ROM and export the necessary data towards it. I need to do it that way, because some of the users who really need this data will be using stand alone computers.The application gets it's data from a mdb-file and the connection remains open as long a person works with the application (maybe not the best way to do, but I know :-) )...when the user uses the application, he can perform an export...this exports the .ini-file and pictures (which works fine), but he also needs to export the mdb behind the application...I already tried connection.close() before and connection.open() after the System.IO.File.Copy...but that doesn't seems to work.

So im trying to allow the user to send a message to an application on a server telling it to do different things. So i build the client and the server side applications and tested them on my computer and another computer here. Everything worked great, just like i wanted it to.
When I moved the server application to the actual server and tried connection via the internet, it did not work. I got the error message: An error has occured : A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond IPADDRESS:PORT
Well then I realized chances are a VPN connection to my server and using my servers name instead of my servers IPADDRESS would fix this problem, which it did.
I dont want to require the user to have to create a VPN connection, i dont really care reather they use the IPaddress or not, although if theres a fix for that too it would be great. Heres my code: (I have marked where the error occured)

I'm Writing a class to Encapsulate the RegisterHotkey Windows API, So I needed a Message Loop to catch the WM_HOTKEY message and I was directed to use a ApplicationContext as a replacement of my form, and then I needed to add a Class that Implements IMessageFilter to monitor the Window Messages.

The click-once publisher generally includes an uninstall program with the applications. when Ive had this problem before it was fixed by republishing as a newer version.

I believe I have found a solution! I will be continuing testing to make sure it DOES in fact work, but I'm hopeful :) I have detailed how I found the solution in EDIT THREE of the question.
For anyone wishing to know the full background behind my problem and what I have kind of tried as a result of input from this question, see this: [url]
I will be editing this frequently (>3 times a day most weekdays) as I progress my research and situation, so keep checking back if you are interested or have some information or knowledge of my issue :)
Quick Background:
I have this app I have made that can be crashed by changing my screen saver or locking my work station, and in general whenever a WM_WININICHANGE/WM_SETTINGSCHANGE message is sent to it.
If I can consistently crash my app by changing my screensaver, then SOME part of doing that is sending my app SOME kind of message (not necessarily a windows message, I mean message in the most general sense), which in turn is catastrophic to my application. Due to this, I am trying to find a way to block whatever message is causing my problem from being processed by my application. I am aware this isn't the best way to go about a solution, so you don't need to tell me. Look at the backgroung info or ask why if that bothers you (there is a good reason).
