Launch A New App And Remove The Calling App From Any Open Processes?
Apr 8, 2011
I am writing an updater for our application and having an issue overwriting the files. Here is a long drawn out example. Test.exe is our main app and update.exe is our updater application. Test.exe needs to launch update.exe and then close test.exe. Update.exe will download the new updates from our website to a temp directory and then copy in the new updates. The problem I have is when Test.exe has an update and I try to copy in the new file it says it can't because test.exe is still in use. I "believe" this happens because test.exe is still running in the appdomain because update.exe was launched from test.exe before I closed that app.
I have a quenstion to discus: I'm using Process.Start() and somettimes it's not worked properly. I meanin start application instantly or with random delays, even with hang's. So, as i wrote in title, there is a some proper way to launch another aplication?
I'm trying to write a some sort of launcher for user specific application based on createble profiles. In each profile user can set a file name (*.exe) with must be launched one or several times.[code]....
how to add other version of .net framework. like 1.0 or 1.1 .net framework here is my problem i deploy my application, when i install, it always say to download or install the .net framework. i want to run my application under windows xp cause our client does not update their machine.
Basically, I'm trying to get a program to behave in the following way:First instance of the program opens up on PC1, opens a file for Read/Write access and then acts as the master program, doing a bunch of work on some other files I don't want a whole bunch of users accessing at once.Second instance of the program starts up, tries to open the file for Read/Write access, fails, enters Slave mode, opens the file for Read access, and periodically reads the status of the other files from this file.
That's the plan, anyway. If anyone can suggest a better way to handle the master/slave decision-making.Anyway, as a lead-up to implementation, I've got two instances of Visual Studio open. One is running a project called "GetFile", the other is running a project called "TryGetFile"."GetFile" has a Private myStream As IO.FileStream object and opens the test file using this line:
This works fine and, as far as I can tell, should leave this file accessible for further Read/Write access by any other process, which is fine for this stage of the testing."TryGetFile" also has a Private myStream As IO.FileStream object, but it attempts the following open code:
This doesn't work at all. I get an IOException, which reports that test.txt is opened by another process and I'm not allowed to play with it.Basically, I don't see what the problem is; I don't think "TryGetFile" is asking for any file access which "GetFile" forbids it from having. As far as I can see, "GetFile" shouldn't be forbidding any kind of access at all...
would like to know if it is possible to have my application launch and open a file which will be called todays date. its just a simple text file and i am basing it on the streamreader style function.
I have made a little programme where the user can put in a name to search for a contact.The matches then fill a Datagrid and the user can then choose the one they want and the programm then opens the contact form (from outlook client)The Contact form opens ok, and it brings up the correct contact. If the user then selects the option to "Email" from that from I then get the error message"A Dialog is open" etc...
My code is as follows
Sub GetContact() Dim objOutlook As Outlook.Application Dim objNS As Outlook.NameSpace
[code]....
It seems to be due to Outlook being open or opening?
Can a data grid in another open form be refreshed by calling a sub routine? This app has a form with 2 data grids. When the user double click on one of the grids another form is opened that shows data details. After the user changes the details the user clicks a save button. We have placed this code in the Closing event of the the details form.
Private Sub FormParents_FormClosing(sender As System.Object, e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing FormParentsAndStudents.RefreshDataGrids() End Sub
[Code]...
Can you tell us what additional coding is needed to refresh this data or if we are using the incorrect place to call this code from within the details form?
My routine to check for updates is run as a separate process. Exiting the application is required to update, so a dialog asks the user, when an update is found, if they want to exit now. f they do, the code (from the update thread) calls Application.Exit().However, if the FormClosed event of any form that needs to be closed needs to access its controls, an invalid cross-thread operation is detected (which sounds pretty logical).
Just had to remove remove statics and use Delegates refering to class. i have got a little problem in one of my project.I need help to resolve it.My application Connect several FTP server with the same Class.I'm using TCPclient for few specifics Commands.The problem : All threads call the same TCPclient wich can't connect several server at once.I would like to create a New TCPclient for each thread.

For some time ago i have notice that my App on every start make a call to csc.exe and starts it. I know for sure that that did not happened before and I can not find out why this is happening now, or better to say: what did I do in code to make this happened? I have google-it and found out that csc.exe is some kind off on-the-fly compiler for C# (If I understand it correctly ) but my App is in VB.net so I am a bit confused. Can someone explain it to me in general what have I did in my VB.NET code to make my App on every start calls csc.exe?
i have a small issue while developing a windows application using VB.Net . i will explain the scenario here. My application contains one form which has two tab buttons. say tab1 and tab2. In tab1, i have an option to download data from various sites. this takes few minutes. lets say 15 minutes. and in tab2 i have an option to view the logs. my problem is i am unable to click the tab2 unless and untill the downloading finish. my doubt is how to do more than processes at the same time. if i am right we need to use threading concept here.
I have a need to search for a specific process in task manager and attach (dock) my application to the window for that process. I have this working just fine. The problem I'm having is that sometimes this process may be running more than once (for example: running two Internet Explorers would put two iexplore.exe entries in Task Manager).
Is there a way to get the one that was opened first? I'm not sure how they get "sorted" in the Process list, but currently I am retrieving the first occurrence of the process and docking to it, but I'm finding that it isn't always the correct one. How can I make it always dock to the process entry that was opened first?
I'm building my first application in VB2010, this application consists of running 3 different programs; one after the other. I use a progress bar for task progress. My question is on how to make the application go to the next program after finishing with the previous one? Here is some of the code:
Private Sub Timer1_Tick_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick ProgressBar1.Increment(1) If ProgressBar1.Value = 3 Then
I have done a lot of searching and cannot find a solution to my problem of, my application appearing in the processes even after exit.
Note: It doesnt appear in the processes due to the type of exit i have used after the click function happens.
Public Class FCAM Public Sub Launch(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Launch_FCAM_FarCry.Click Process.Start("....Bin32FarCry.exe", "-MOD:FCAM") System.Windows.Forms.Application.Exit()
I am trying to check for certain processes that is running and then inform the user of those processes via textbox like "The programs; -name of the processes running goes here- are running". [code]
DLLs made with VB.Net are different from DLLs made from other ways (i.e. with VB6). I wasn't albe to understand the cause. It might .NET has a bug.[code]...
i am trying to develop a program that will get all the processes in the task manager and from there, i'll get a specific application so that i will restart it. the problem is this:
I can call that specific application yet before restarting it i shall manipulate it's pause button before i can actually kill it,.HOw do i "click" the pause button on the called application? Can you help me with the code that i need to use?
Trying to dim a certain amount of process (determined by Environment.ProcessorCount) to run several processes which do not support multi-threading. I have already Dim'd proinf(6) as Process.ProcessStartInfo because I have designed a queue for the processes and this encounters no errors.
I am looking for some code that will end the processes of a running program. I have found many post on how to do so but I have found that they are over complicating things. I am using this code to see if a processes is running.
code Dim ProcessRuning() As Process ProcessRuning = Process.GetProcessesByName("example") Do While ProcessRuning.Length <> 0
