The DataSet consists of one table with several rows and a bunch of columns. What I am trying to do is get the data for one specific row and column so that I can use this data is some calculations. I can position the row if I need to but I can't figure out how to get the data in the specific column I need.
View 3 RepliesVS 2010 - Search Dataset For Specific Record
Aug 1, 2011My application will start (dataset filtered by username/date) and if it's the first time the user has used it today it will be a blank entry form because there is no record for today created. The user can just type data into the blank form and close it. On the form closing event I want it to run a tableadapter.insert(username, date, x,x,x).
If it starts a second time it will load showing today's entry because today's date was inserted previously when they closed the form. So this time when they close the form I want the form closing event to just run a tableadapter.updateall(dataset) command. I need some help with my form closing event...

Check 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)

Check Box That The Use Checks To Indicate That A Specific Situation Is Present
Jan 26, 2012I have a Check Box that the use checks to indicate that a specific situation is present. When the User checks the box he gets a Message Box reminding him that the condition must be fulfilled. This works fine and the database reflectthe fact that the Check Box is filled.
At a later date, if the user calls this record and fills the form, the Check Box is triggered and the message Box appears in the middle of the form fill operation.
Is there a way to prevent this from happening. I want the Check Box checked but don't want the message box if the change is triggered by the fill process.
