i am trying to use the sleep command in vb 2008 multiple times to constantly change back color but am told, Unable to load DLL 'Kernel 32': The specified module could not be found. (Exception from HRESULT: 0x8007007E). i tried it with another program and one sleep(1000) and it worked so is there a way to use this multiple times or any other command.ian hendry

I have a 4 table database and need to query at least 2 tables (the single table query works fine). The output goes in textboxes / labels on an existing form.
I'm trying something like this:

Currently I'm using System.Threading.Thread.Sleep(5000) to let my app pause/sleep for some time. This works great but I can't open my app anymore when it's sleeping and it uses about 25% of my CPU. I guess there must be a better way to do this. I also tried using a timer but that didn't work out to well for me..
View 5 RepliesThe coding that I have a problem with might make people think that I am creating some malware or something stupid. So the project I am doing is associated with iTunes. iTunes allows people to have one library. There is another way, but it is very confusing to some people, and very unreliable. So my project is that I will allow people to have multiple iTunes libraries on one computer. So the problem is this. In order to have an option to choose your library, I gotta make sure that iTunes is not running. So this is the script:
Code:
Private Sub CheckAndCloseiTunes()
retry:
'Custom class that includes the function to safely close iTunes

So when I use the Threading.Thread.Sleep(2000) code, the form becomes unresponsive.
I want to create a daemon thread that sleeps for 30 seconds and looks in a directory for a database then opens the database.

View 1 RepliesTitle pretty much says it all. Does anyone know a way to to prevent a computer from entering a low/non-processing mode while the program is running? I don't care about monitor modes, screen-savers, hard-drive spindown, etc (in fact, I'd prefer to leave those alone; I like it that it shuts the monitor off after a time period).Basically, I have an industrial program that needs to continually monitor a PCI card it uses for IO; and this activity alone isn't enough to convince Windows not to go into Sleep mode. We normally just shut the power-save features off, but we had an incident where a technician forgot, a customer's machine went to Sleep after the end of the shift, the pumps stopped recirculating, yadda-yadda big mess.

The problem - The btnPause doesn't pop up until AFTER the thread sleeps, but the other two buttons works correctly. What the heck is going on? Here, I'm using the Sleep to simulate doing external events yet to be programmed.

I am making a program for me and I told my friend about it and they said that they would like to test it. The only problem is that they don't have VB2008, and there seems to be no way to compile my program so that another person WITHOUT VB can use it. Does anyone have any tips, or perhaps I'm missing something? Let me know ASAP

I have built up an interface in VB2008 with many textboxs and labels on. When I click "New", I would like to clear all the textboxs and labels, i.e. each with a NULL value. Meanwhile, I also would like to clear all the arrays behind the program, i.e. the arrays which are not shown on the interface but is important for the calculation.The only way I could find out now is to clear the textboxs, labels and arrays one by one. So if there are 100 textboxs, 100 arrays, I have to write 200 lines in total. Obviously, it is not expected. Is there any other quick ways to directly reset everything to the beginning when the interface is just opened?
View 5 RepliesI'm trying to get a VB2008 multi thread application working that connects to a local server program using sockets. Server requests for this particular system can be more quickly handled by a number of connections, so I've written some code to run any number of data request threads that I choose. The problem that I'm having is that the data returned from the server is getting mixed up and is often returned to a different thread/socket than the one that requested it. Other than that, it seems to work okay. If I use just one thread, then the system works as it should. Pls. see incuded code, which is heavily edited to remove all the other fruit salad. Is there any way to set up the sockets so that data returned to the socket/thread that requested it?
