here is my script:

Im building an application in vb 2010 which uses window media player component. When I run the application in debug mode and Press Play button, the application hangs up and stops responding. When I press PAUSE button in vb 2010 the line it shows is
mediaPlayer.URL = curl
My mdi VB.Net application performs a long operation on some data. Ideally I should use a separate thread to prevent the dreaded "Not Responding" message.My problem is if I use a separate thread users then have the ability to click on other controls in the application which can directly affect the operation my background thread is working on, creating an error.
Is there any way to prevent all the mdi windows, toolbars and other controls from receiving mouse clicks and keyboard input during my background thread's operation?
Or is there a way to clear the message que before performing a Application.DoEvents?
Is BindingSource class makes use of Threading to read and write the values in controls and in objects?I mean how bindingsource know when properties of an object changes and sometimes seems not to know? Does it use a kind of BackGroundWorker running to watch changes on bindings objects? And why does it sometimes read and write properties so many times the same value on the same object's property?I found that it's sometimes easier not to use them since it's hard to know why a control do not update but, on the other hand, dealing with control events can be tedious. And what if i tried to make my own BindingSource Class not inherited from the System.Form.BindingSource
View 2 RepliesI've been working on a program that generates a batch file, then when you press a button, it executes that batch file. There are multiple batch files attached to each item in the list box.
[code]...
The only thing that it does when I press the button, is starts the batch file, then goes to function searchtitle, which executes the batch file again when it finds out it didn't work properly.The button text doesn't change, none of the items are being added to my first list box, and I can't do anything to the window after pressing the button. It constantly opens the batch file every 5 seconds or so.
I have written a very simple program to simulate the operation of some electrical relays which respond to buttons pressed on a form.The important thing in the program is the pick and drop times of the relays so I use about 40 timers to simulate the operation
of the relays each stimulated either by another timer or the operation of a mousedown operation over an area of the window which has a GIF background.
The program works great when simulated within VB2010 Xpress but when I publish and install on either of my 2 laptops it freezes and does not respond to the mousedown procedures. It seems slightly better if I don't enable XP visual syles but still does not respond enough to be used. I am running 12 procs each time a continous timer runs out but altering the value of the timer does not make any difference. I've also noticed if I minimise the window and reopen the window it does move on slightly but still never responds to the mouse.
Also the timers in the program for the relay times seem to work at strange values and not those set sometimes? It seems to work OK on my main PC if I install it
I am making a mass emailing system that reads off of a xml document and sends an email based on the stored object made from the XML tags.This program will have to send hundreds if not thousands of emails out. I made a test XML document with 160 emails to be sent out to my address.The program gets a (not responding) after about 10-15 emails, (although it keeps sending). Also the email sent counter lable doesn't change at all during the sending, the progress bar works however.Also, when I tried running it it stopped at 140 emails.
' Algorithm
' Show the progress bar
ProgressBar.Visible = True
[code]...
In a function I have
Do Until PageLoaded() = True
{
Nothing
}
The problem is it freezes up the program and makes it unusable. I fixed it using timers but it makes my program real sloppy and hard to edit.

I am working on a program which makes tables in MS WORD. But there are many parameters that should be asked. Its so embarrassing to ask all of them with inputbox while codes are working. I made forms for each tables which will be created. While codes are working, when it is the time to create table, form appears and user inputs the datas and press OK button and table is build according to these datas in MS Word. Does anyone has an idea ?
View 1 RepliesI have created a little program that helps me keep track of tons of data by inserting it into sql. I created 5 forms and all 5 can insert data at the same time, but mostly just 1 of these is working continuously. I have noticed that the program will run, then at random times it will stop responding (can't minimize/click on anything/data entry stops), and the only way to stop is to kill the task. I can't even click in the debugger to set a break point when it happens, and setting breakpoints before debugging is useless as the program could run 2 hours and stop, or 10 minutes and stop. 5 forms, they open different excel files, insert data into sql, and repeat.

Im trying to make a program that makes a user type in a password, then open a folder where the user can put files. but once they close out of the file browser. the program needs to save the files and remove the directory. for example think of a file cabinet being the program, and the drawer being the temp folder. when the user closes the drawer, it goes back into the cabinet, or in this case the program.

View 2 RepliesI am trying to create a program in Visual Basic which will measure the performance of the CPU with every core, one at a time. In this program, I decided to place a couple of text boxes that display the processor speed and the actual processor speed. I need to get the actual processor speed to update and I have tried doing this already using a timer set to tick every second. However, when I load the program it runs really slowly and prevents me form doing anything within the program, including trying to close it down, and all it does is updates the text box every second. I have looked in task manager to find out how much CPU the program is using and it shows that my program is using 0 - 3% CPU.
Here is the code currently use
Private Sub Timer3_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer3.Tick

View 10 RepliesI have an application that I need to automate where at a certain time each day, say 6pm, it will run a certain method(which is to check a database for key terms and then access the api to search for these terms). But there is the main process which is running all the time accessing the stream api so when the search is complete, it interrupts the stream and hands over the new terms. Now I thought of adding the .exe file to windows task scheduler but not sure if that would work. The stream method runs indefinitely and at 6pm each day another process needs to run. I thought of using the system.threading.task TaskFactory but I am using visual studio 2008 ( I do have .net framework 4.0)If it launches using the task scheduler as 6pm with my code logic as follows:[code]
I see how this would eat the CPU...the streaming process is basically following a list of user profiles listening for new activites and storing these as XML files. This a real time feed to an API. At a specific time once a day, a second process needs to go access a database for new ids, and if there are new ids, then go to a search API and get new user profiles. This is the main criteria..once the new user profiles are found, the list that the stream users needs to be updated so the process will be interrupted for a second or just paused and then continue processing.
