I'm trying to work out how i can make my multithreaded app stop at a certain point and wait for the user to type something into a text box and click ok. It must then carry on and when a different thread gets to that point it stops again and waits for the user to input some text again.
View 1 RepliesI want to be able to run a thread and then at a certain point pause it and wait for the user to enter some text into a text box and then when they press submit i want the program to run again from where it left off.
View 10 RepliesI got an text file that record data, and I need to read the data and do some comparisons. All data read will be showed in a form. If the data is fail, I need to show an alert to the user and wait for user to respond. If user responded to the alert, the program will continue to read data and do comparisons. The issue that I'm facing is that I don't know how to continue read file from the last read point.

I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.

I am restarting a service, I need to wait in between the NET STOP and the NET START, I am using .NET 2008,
View 3 RepliesAfter trying to make an application multithreaded, almost towards the end of the processing of 10,000 records, I get a webexception - operation timeout.Now it seems to process around 8000 records just fine, for each record it is also doing some business logic and with it, performing a call to a webservice.
without threading, its fine - no problems. with threading, we hit the issue.so there are 10,000 records to go through. this is of course slow when done in sync mode (Single threading) but much faster when placing items in the threadpool and waiting until completion.
im not sure exactly why the problem happens. how should I debug this when multithreading? its just odd that for around 3/4 of records, the calls are doing very well, then on the last bit to go, it bombs out.
again - no issues when single threading.update: seems to be after around 1000 records that have been processed that it seems to happen.the application calls out to an internal webservice which then does the direct callout to the "outside world" webservice. The internal webservice does some caching but shouldnt have any effect really.
The outside service it is calling is httpBinding. ReceiveTimeout is set to 00:10:00 (10 minutes) and bypassProxyOnLocal="false"im still not quite understanding why it would timeout after 1000 records because it seems to process the others just fine and does come back (or so it seems) when its making a call to the service
Can I stop updating the user display of a control (rich text box) temporarily? I want it to process what I tell but not change how it looks for just a small piece of code.
View 5 RepliesI'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.
View 5 RepliesI have a picturebox that is moving across the screen. At the moment I want it too stop at a certain point until a button that is called next is pressed. I then want the picture box to carry on moving across the screen (The total number of times I want this to happen is 5)

Dim x As Integer = 144
Dim y As Integer = 44

View 5 RepliesI have the following
Public Class Form1
Private GIFAnim As Image = Image.FromFile("c:cointosscointoss_ani.gif")
Private frames As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[CODE]...
Now I would like to put a wait in after the line:
frames = GIFAnim.GetFrameCount(Imaging.FrameDimension.Time)
ImageAnimator.Animate(GIFAnim, AddressOf paintFrame)
This is so that the animation has time to play and stop and then the rest of the code will display the other picture and the numbers. Is this possible? I tried timer and sleep but I cant get them to work.
I'm planning to make a program that Allows the user to type in the Download Link of another program, and then Run it. I do not want the file to be saved on the user computer.
View 1 RepliesIm 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 have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?
On my login form I have a username text box and a password text box...
The TxtUsername text box is preset with the following:
Text: Username
Colour: Gray
Here is the code for the TxtUsername (on click):
Private Sub TxtUsername_Click
TxtUsername.Text = ""
TxtUsername.ForeColor = Color.Black
(So it's like the facebook login if your familiar with it)When user clicks the text box, the gray text already inside gets erased and user is able to type with black text.The problem is that even when the user has typed in the box, every time you click the text box the text still gets erased....It's like the code should be something like If TxtUsername.Text = Anything but "Username" then dont change it to ""
I need to record the screen when my user clicks start, and stop recording when he clicks stop.I've searched for a while on this subject, and I have found nothing.I want to do this without adding any files to my project, I just want to use some built in function in Visual Basic, and start recording, or even take a snapshot and add it to an AVI file or something...These are some sites I have found:

In VB.NET I've got two forms, on first one I have button, on second - two textboxes and "OK" button. I want to run procedure (Sub) on first form, then stop in the middle of it and wait for input on the second form. After that i want to process the data received from second form.
It looks something like this:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Open form2 for input

The question is how to call the Form2 so that procedure is stoped till the second form is closed?

View 5 RepliesI have a text box labled QTY, which feeds the QTY column on a datatable. the table then is ran through a function that takes the data and converts it to a string which my production machine can read. My problem is this, and its probably really simple (these problems usually are) how to i force the user to use a specific type of input on the txtbox so they would have to put the QTY in the format of 01 02 03 etc etc, i have it set to default to 00 but i want to force the user to haver to input 2 chars.

I have a searchbox that queries a database and shows the results in a box below. This is kinda slow when I use the ontextchanged event, cause the database gets queried each time a new letter is written.
How can I make it only do the query when the user is done writing, or each time the user takes a small break?
