I am trying to kill the duplicate fields in a DataGridView. I have it alphabetize all the items in the DGV and then compare each item down the DGV as long as it is either equal to or alphabetically lower than the next item in the DGV.Here is the code I'm using:
Do While X < data.Rows.Count - 1
' Compare 2 items next to eachother
compareResult = String.Compare(data.Item(0, X).Value, data.Item(0, Y).Value, True)

As I run it through more largely populated DGVs (200k items), I run into an InvalidOperationException saying that rowIndex=190000 (just some high number) is an invalid value for rowIndex.The error seems to appear more or less randomly.When tested on DGVs with 20k items, it seems to complete fine (though it may just be luck and the error isn't popping up).
I want to be able to disable Alt+F4 and the X button. I was able to do that, but it disabled Close() too. I want my app to be able to terminate its own process. How would I do that?

View 8 RepliesI am developing an application which launch an external windows app, ei called APL.exe Also, this APL.exe launch two console utils, ie. named CON1.exe and CON2.exe I would like to know if is there any way, after APL.exe has died, of killing CON1.exe and CON2.exe, because there is a small possibility that they will not died completly after APL.exe has exited.Also there is another requirement. My final app version could be executed twice in the same machine, so there could be two instances of CON1.exe and CON2.exe, and because this I need a way to kill them not by process name, but knowing which of them has been launched by my current application instance.

View 1 RepliesWhen starting my application, I have a couple of classes which are required to read certain files in order to create a set of default data. The logical place (to me) to do this is in a Shared class constructor; the idea would be to throw a class-level event if the reading of the defaults file fails. Unfortunately, this does not work as attempting to access such an event, in order to attach a handler to it, fires the class constructor before the event has been attached. In a failing case, the constructor starts, fires the fail event, the constructor completes, and then the event handler is attached, after the event has fired.
The only other solution I can think of is to give the class a "typeInitialisedSuccessfully" boolean property and put a try/catch block around every call to construct an instance of the class, which seems unnecessarily kludgey to me. Can someone suggest a more elegant solution?
EDIT: Because this is a fundamental Class, used in one form or another across nearly all of our software tools, I would greatly prefer a solution that will notify future programmers that the type initialiser needs to be called, which is why I initially went towards the Shared Constructor as a solution.
How can I kill the excel.exe process in SSIS during the data flow task when it fails? There could be multiple instances of Excel.exe running from other packages that are perfectly valid so I don't want to loop through all instances killing them.My problem is that during the data flow task the process will sometimes fail due to a sheet that is named incorrectly or missing columns. This keeps an instance of excel.exe running which is now an orphan task eating up resources so it needs to be killed.At the same time there are other SSIS packages running that are accessing their own excel.exe process and aren't having any issues. So how can I kill the orphan excel.exe process without impacting the other excel.exe process?

View 1 RepliesI am sending data to some microchips with a serial port control using:
Code:
well, it work up to the value 9, but anything with more that one decimal place sends a byte value of the rightmost digit. So, 16 in the text box will send 6. Basically, it appears to be sending just 6, or 1 followed by 6. Is this how the serial port sends data...one digital at a time? Or, is the conversion to a byte failing?
Is there any easy way to determine the IP address for the computer that an app is running on. I looked through the System.Net namespace and didn't see anything of the sort.
Basically, I want to display the IP address to the user, instead of walking them through how to do an "ipconfig". They then can put that IP address into another app, so the one app can talk to the other via UDP.
