I have a windows service that I have written. Each time i start the service, it performs the task that i want just fine, but after that it stop executing even though it shows that the service has started and is running. The service reads files that are dumped in a directory and writes the info for each file to a DB, then deletes the files.
Again, each time i start the service, it runs just fine but then does not loop...so it just runs only once.So if i continue to dump files into the directory during the day, the service does not detect the ones that where added after it started. Right now,I am forced to manually restart the service to pick up the files that were dumped after the last restart. Does anyone know how I can get this to keep looping periodically to detect files that have been dumped in the directory? Here is what my code looks like so far.. also, how do i make changes to this code to show errors?
Public Class FileDetector
Dim sweeperThread As Thread = Nothing
Protected Overrides Sub OnStart(ByVal args() As String).[code]....
I tried it every way I can think off, but nothing can stop it .

View 1 RepliesIm using a windows media player and i want to make it loop. In the properties the player counts only lets you go up to 999 times play count. i want it to loop until the form closes. Problem is I dont know how to make calls to the object.
The main idea is to use the media player to play my back ground sound and use a button to play my sound fx sound and they don't stop each other from playing. Its works so far but I only get a play count of 999, so I want to change that to a endless loop.
Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

I had created a windows forms application in vb.net. It contained several windows. Now the users of that application are telling me to display all in one main form. They want to see all the details in one form. I had implemented MDI but they want something like tabs. On different tabs different forms should be displayed. How shall I implement this.

I have a solution with several projects most of which are code or control libraries. I have a main windows forms application that references and uses these libraries. What i am trying to do is create a 2nd windows application that extends the main one, but i would like to be able to deploy them as separate exe's.
When i try to add a reference to the new app referencing the main app; all seems fine until i try to run the new app i get several error msgs similar to below:
Error 1 Could not find file 'ADODB.dll' referenced by assembly 'D:Visual Studio 2005ProjectsXXXinDebugXXX.exe.manifest'. <newAppName>
i have tried adding references to all the dll's in the error messages and they are still listed when i try to run the new app. I thought of a few work arounds but they require user changes to maintain separate exe's at deployment. I would like to avoid this if possible.
in the program im trying to make i have a button that when clicked starts a fairly lengthly loop, takes a couple minutes to complete. while this is happening im trying to send the an update of the loops progress to a listbox i have setup. Unfortunately these updates dont make it to the list box until the loop is finished, ive tried this with a few different types (progress bar/ rich text box etc). i cant seem to get any form changes through while the loop is in progress.
Is there some option or event thing i need to specify to be able to make changes to the form while in a loop?

I'm building a code editor app in VB.NET (Framework 4.0) and it opens all ".por" files into individual forms consisting of a MenuBar and TextBox (multi-line).Currently I have 20 forms (all duplicates of the first on I designed) and if there are say 4 ".por" files in a directory, the first four will open up while the others hide.
I think it would be far more efficient by coding a new form For each item in form1's ListView...but I want the next so many to be a copy of the first form I designed since I spent a good bit on it.
