View 4 RepliesI have a number of tabpages that each contain a datagridview control only. Based on the results of a SQL statement I then loop through each tabpage and set its name. The reason for this is that at runtime (and depending on the results of the SQL statement), the contents of each tab page will change - henceI loop through the tabpages and set the name/ text (to reflect what will later be shown in the DataGridView)
The datagridview control on each tab has the default name e.g. DataGridView1, DataGridView2, DataGridView3 so it's easy for me to loop through them e.g.:
for i as integer = 1 to 3

I am developing an intranet app (so security isn't such a problem). The client wants to drag eml files from Outlook to a folder. I would like put a file watcher control that monitors the folder. When the new file is added I want to run some javascript in the open intranet window. How can the file watcher app communicate with the intranet app (also there may be more than one intranet app open). I am experienced at asp.net but a total novice to Winforms so bear with me.

I use a Java web app (app/screenshot, you'd need to sign up, but it's just a java web app), however I'd like to automate its functionality inside of a .NET application (C# or VB, doesn't matter, I'd prefer C#).
I've tried searching but unfortunately "Java web" and ".NET" and "C#" etc, don't return me anything even remotely useful. Is it possible to load the page within a control (or through some other way) within a .NET application, and thus act upon the display itself (the data flow will be encrypted, since it's https - so I don't know if I'd be able to read the data coming to and from the java application, I assume not, but being able to read the application would be nice), to be able to select areas, click, read/input numbers and text, etc. I realize this is a pretty broad question, but, it'd be very helpful if someone could offer some advice/insight into this problem.
edit to add: I guess a better question would have been either "Ways to interact with a java web-start app with windows apis?" or "Possible to contain a java web-start app within a .NET app, and interact directly with components of the web app". I'm also wondering if it will be possible to load it into a browser in a form in .NET, although I assume that it would just launch web-start taking it out of the forms control.

I have 2 columns in a datagridview bound to datasource. When the user checks off one checkbox, i want to check some business logic after which I set the 2nd check box in the same row as checked as well.
My problem is: I want to check the 2nd check box right after the user clicks on the first checkbox and not only after he tabs away by clicking somewhere else.
Right now, I only succeed runing my business logic in the CellValueChanged or CellParsing events but those only occur after the user leaves the checkbox, which is not desired, I d like to run the logic and show the 2nd checkbox checked right after the user clicks on the 1st checkbox.
I also tried: CellClick event but I don t know how to : when the user clicks on a a checkbox, how to change the value of other checkboxes in the current row during CellClick event . The changes does not take effect in the UI !!!

It's been a while since I've programmed in Visual Basic 6 and very recently nose-dived into Visul Basic 2008 and .NET 3.5 Compact Framework. Hence I'm now becoming a bit stuck. This is NOT homework but a self imposed personal assignment. Only person who will mark it is me, being happy it'll work. Trying to recall and refresh my pprogramming skills the hard way.
I have so far written a program under VB2008 that executed on a WinCE device of which I have to have the terminal connected to the computer as WinCE is not emulated under Visual Studio. I've got the thing reading and writing files on the device using file streams so in a nut shell the sample application I have got working that can write data, find data and amend data.
Now here is where I am becoming stuck. I am now turning my sight on using Microsoft's compact SQL server. To date I have created the data table on the WinCE device using VS2008's data explorer so a database has been created and using the data explorer I can read and write data to the SDF file on the device. (Data Explorer talks to the compact SQL server on the WinCE device via an ActiceSync connection.)
