View 5 RepliesTimer Only Running Once?
Nov 24, 2010If a function returns false it is supposed to delete a file and then call the MyTimer.QuickFire event to relaunch the sub. It does this only 1 time, however my problem is that it might return false multiple times before all the function return true. The HourDownload Sub is set to fire every at hour at 5 minutes after the hour, the data could be valid at this time or it might not be valid until 40 to 50 minutes after the hour. So the quickfire event would need to run multiple times until everything returns true and the sub is exited. I also have another Sub Called FiveMinuteDownload that runs every 5 minutes, which is basically identical in structure to the HourDownload Sub. Both of these Subs call the QuickFire event in the event that a function returns false, however both only run once.
Private Sub HourDownload()
DeleteFileHour()
If OneHour() = True Then
If validateOneHourxml() = True Then 'Calls the validateOneHourxml function to see if the xml file is valid or not(if it is valid then it goes onto the next step, if it is not valid then it should call the MyTimer.QuickFire(2) which is a 30 second timer to relauch the HourDownload Sub.)
If HourImport() = True then
DeleteFileHour()
Exit Sub

Create A Timer While The Application Is Running?
May 16, 2012I want to create a timer while the application is running. For example, the form has TextBox1 and Button1. When Button1 is clicked, the timer will be enabled and will print the current system time in TextBox1 every 10 seconds. The timer will be disabled when the Button1 is clicked again. How do I implement the timer and its events? An example with both Windows Forms and Silverlight would be great.
View 7 RepliesRunning Calculations In A Schedule (not Timer Type)
Jun 9, 2011I have a bunch of calculations, which will run down for x amount of years or months, specified by the user. These will be in a table (datagridview or something similar), which I will need to access to create reports. So basically calculating the data, then dragging various values at intervals. So it could be any cell at random or patterned. An example of this would be watching how much tax a person paid per year, and how much their income was per year. A pretty basic example. So there would be two columns, and x amount of rows depending on what the user wants to see, in this example, the next 48 months, in months not years. The user then decides to take every 12th value and putting that straight into a report, showing their expected schedule for tax and income.What sort of table structure would be the best to use? The table should be created automatically each time the event (for examples sake a button) is clicked. I'm not sure what I need the event to be based on yet. Most likely the form loading, or when the user tabs onto a new area. Should I use a datagrid view?

Calling .dll Method From Inside A Timer Won't Work(Console Application)?

This .dll contains a sub called ReadDeviceBlock2(byval devicename as string, byval size as integer, byref data as short). When I call this method in my main it works fine, if I call it from another method that was called by main it works as well.However, it doesn't work when I call it from my Timer_Elapsed sub? I guess this has to do something with threads but I can't figure it out.

View 4 RepliesCheck For Instance Of A Specific Exe(s) Already Running?
May 10, 2011I'm wanting to add a some extra code within my application. My app is a single form that sets some environment variables before calling a one of two possible 3rd party executables to run. I have set via regedit the file association for files to open via my app but what I want to do is have my app check to see if either 3rd party app is already running. In short I'm trying to ensure either 3rd party app stays as a single instance.
If a user were to try an open another instance: 1) my application should simply terminate (no warnings, no msg boxes etc...) 2)the file that the user was trying to open should open within the existing instance of the 3rd party application. The problem is I don't quite know how to achieve both parts I imagine that this 'instance check' should happen as the first bit of code so that if no instance of either 3rd party app is found, then proceed with rest of my application. I have tested using some lines of code at the top of Sub New(). Here's what I have so far for checking for both 3rd party applications:
Public Sub New()
If IsProcessRunning("ustation") = True Then
Me.Close()
[code]....
This gives me an error when I debug (Cannot access a disposed object)
Discovering If A Specific Program Is Running?
Oct 8, 2010Is there a way of discovering if a specific program is running?
I want be able to call a program but have it wait to execute until another program has closed. Both these programs are in the Startup folder so I may have to make them mutually exclusive so that which ever starts second has to wait for the other to close. In the case of these two programs it's of no consequence which actually executes first, although it would be interesting to know if I could actually wait for one to open and close before executing the other.

View 3 RepliesPreferred Method To Catch Specific OleDB Error
Jan 4, 2010I have a situation in which I must execute a dynamically built stored procedure against tables that may, or may not be in the database. The data retrieved is then shunted to a VB.Net backed ASP based report page. By design, if the tables are not present in the database, the relevant data is automatically hidden on the report page. Currently, I'm doing this by checking for the inevitable error, and hiding the div in the catch block. A bit kludgy, but it worked.I can't include the VB code-behind, but the relevant stored procedure is included below.However, a problem with this method was recently brought to my attention when, for no apparent reason, the div was being hidden even though the proper data was available. As it turned out, the user trying to select the table in the dynamic SQL call didn't have the proper select permissions, an easy enough fix once I could track it down.First and foremost - is there a better way to check for a missing table than through catching the error in the VB.Net codebehind? All things considered, I'd rather save the error checking for an actual error. Secondly, is there a preferred method to squirrel out a particular OLE DB error out of the general object caught by the try->catch block other than just checking the actual stack trace string?
SQL Query - The main gist of the code is that, due to the design of the database, I have to determine the name of the actual table being targeted manually. The database records jobs in a single table, but each job also gets its own table for processing data on the items processed in that job, and it's data from those tables I have to retrieve. Absolutely nothing I can do about this setup, unfortunately. [code]

View 1 RepliesTextbox Text Property Won't Update Programmatically After First Time Running Through A Method (but Will Thereafter)?
Jul 28, 2009This is my first post on this forum, so please excuse me if I'm posting wrong. Anyway, I've been having an issue that I've never seen before and is driving me nut, I have a windows form on which I have placed many textboxes that display information from a MS SQL database. The user can then change these values and hit a "save" button which writes the changes to the database. I also have certain textboxes that with the "on leave" event (after a user enters a possible new value) trigger a method that recalculates some of the other fields based on the new information. Hopefully that all makes sense.
So the problem is, when I run through this "recalc" method the first time around, it doesn't update those textboxes that it's supposed to. However, when I put a breakpoint in and debug through it, the debugger shows it putting in the correct values into the textboxes. It's just as soon as the method is done, it puts them back to blank, or whatever they were before
