VS 2010 Run Another Program In The Background?
Sep 30, 2011
is it possible to call another program in the background? I'n doing a project that uses .net to control a camera. the camera is nikon, which has a sdk. unfortunately, the sdk is an unmanaged dll, from the research I did, people complained that it is difficult to use it in .net. actually, no1 has example. but the sdk has sample in vc++. so, I'm thinking maybe can build the control program by vc++, then use vb.net or c# to it and run it in the background. so, I do not have to mess the dll to .net.
is this a good choice? or, not really? how to do it? if I use a console program, how to avoid popping up the cmd window?

I made a simple code that changes the background color for my program and then save it. But for some reason, it will not work if the RGB code has 255 in it.
Public Class Form1
Dim R, G, B As Integer
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
R = TextBoxR.Text
[CODE]........................

I have Windows XP Pro, SP3 on a Dell Dimension 9150 with VB 3.0 and all other Visual Studios up to and including VS2010 Pro.I'm not exactly an expert VB programmer, but I have written several different programs.I would like to write a VB program to run in the background and detect when the program regedit.exe/regedt32.exe tries to run.Once the regedit program tries to run, I would like my background program to pop up a message with three options. Allow, Do Not Allow and Cancel.
The Allow button would allow regedit to run.The Don't Allow button will not allow regedit to run and continue to run in the background. The Cancel button would not allow regedit to run and would cancel the background program.Can this be done?I would explain why I want to do this, but it would take too much of this thread. However, if anybody really needs to know, I will accommodate their request.

this is really bothering me, my program seems to run faster whenever I click on some other window so the form doesn't have focus. What is going on and how can I fix this?
Here's the troublesome section:
ListView1.Items.Clear()

I am trying to write up a program that has a few forms that you interact with and do various things with but I also need to have a TCP/IP client/server running in the background to handle a automated connection to a PLC. Is there anyway to have the TCP connection open and receiving/sending in the background even when the operator is doing something else?

When you click a button, the program should start op everytime your computer starts, but it must be in the background, so that you wont notice it.

when a user logs into their account on the laptop , Remote Desktop Connection automatically logs them into their account on the main computer. The problem is when it comes to logout, i need to create a vb program that will run in the background , so when the user disconnects from RDC ( which also closes RDC) it automatically logsoff the laptop. hope this makes sense.

I have a form with 3 background workers. On the click of a button all three start async. Once they all finish my program stops responding. If I run one at a time I encounter the same error.

Dim source As String = _Topsource("[URL]" & gamertag.Text)
Dim statstbl As String = source.Remove(0, source.IndexOf("<div class=""statWrap"">"))

I am looking to write a program that runs in the background that monitors the USB ports on a PC. If a specific device gets unplugged I want a message box to come up saying so. Is this possible. I am guessing I would need to query the usb devices for their ID and then write a simple If then statement, however I do not know how to get the IDs of the usb devices.

I have a splash screen for my program that I want to have a background image that changes each time the program opens.One way I saw to do this is to load it from a ImageList, but that has an maximum image size of 256x256.The splash screen is 498 x 305, which means that I need to find something besides ImageList but hopefully with a similar ability to organize the images.I did try just putting them into resources, but wasn't able to get it to set the background without erroring, and I'd prefer not to have 30 images cluttering the place up.

I have the following problem. I have a worker in VB .net (2010) which runs a shell-program. The shell program is a service and output stuff like:
Server initializing...
Server opening port...
more info...
I am able to 'catch' the output of the shell and add it to a textbox (using set text function). And I am able to Cancel the worker by clicking on a stopbutton, however when there is no more output by the shell I cannot stop the worker anymore. At least I suspect that's the case. I've tried checking for endofstream (commented section) but that doesn't work. I've also tried to same code with some test text in stead of 'clsProcess.StandardOutput.ReadLine' and that also works. So I came to the conclusion it must have something to do with clsProcess.StandardOutput.ReadLine being at the end?
Try
clsProcess.StartInfo.UseShellExecute = False
clsProcess.StartInfo.RedirectStandardOutput = True
clsProcess.StartInfo.RedirectStandardError = True
clsProcess.StartInfo.FileName = serverpath + config_executable

I think it's because I have a background image. For example when I maximize the program it lags. I mean big software companies have programs that have more pixel images and are much more colorful then my program is but never lag why. AVG has nice look but the program never lag. But the code runs fine so that is a good thing. How can I stop the lag with background image?

I'm looking to create a program which will run in the background, but will capture any data input by a barcode scanner. Since barcode scanners work more or less as keyboards (I'm not familiar with the specifics of the implementation, but my reading and their behaviour suggests this) my plan was to simply capture all keypresses and look for a distinctive pattern (sequence of numbers entered in improbably fast succession).
I'm a little concerned, however, about the fact that this will require holding up keypresses until I confirm a match. The holdup will probably be barely noticable, but it's still not ideal. My quesetion is: is there any better means of implementation than simple key and pattern detection, for example detecting that the keypresses originate from a barcode scanner?

I would like to have my application basically appear as if it was part of the desktop background, I've removed the form border etc and made the background colour of the form the same as our standard company background so it all blends in nicely. I have also made it so the app does not appear in the toolbar and it is set to launch on startup so it appears as soon as the user logs in - so all works fine and looks fine because any new apps that the user opens will open on top of my app. The only problem is that if they press the Show Desktop button (or use Windows Key + D) to minimize all apps, mine gets minimized as well and disappears. Its easy enough to get the user to make it appear again as it has a system tray icon that they can interact with, but it would be better if it just didn't vanish when they did this.Now I know the best thing for this on Windows 7 would be a Gadget but the problem is that Gadget's annoyingly have to be HTML/javascript and a) I'm not great with web coding and b) I don't think it is even possible to do what my app does from a HTML/javascript page... oh and c) I can't find any way to deploy gadgets in a business network (there is no way we are installing it manually on all 300 of our PCs), so the gadget idea is not looking very promising.I'm wondering if there is some window message I can capture and ignore in the WndProc event handler
