I'm trying to track down a problem on our test environment. Previously it was set to use InProc Session State Type, but I've added in the SQLServer type for one specific Web App. I did this because we use the SQLServer type in our production environment and I want our test env to match as closely as possible.
However, after changing it to SQLServer I do not get any errors when trying to store unserializable data in session like I would expect. It works just fine, even though I would think it shouldn't. I'm a relative newbie when it comes to configuring this, but from the various tutorials I googled, I thought I covered all the bases.I was wondering if there's any code snippets to verify which session state type an application is actively using.

I have two datatables with similar structures that I want to make one existing row to be updated from another datatable.
For example, "tableA" has three columns: "one", "two", and "three"; with "one" being the primary key...
and "tableB" has three columns as well: "one", "two", and "three"; with "one" being the primary key.
Say there is a row on tableA that is different than a row on tableB (with a matching primary key). What I wanted to do, as efficiently as possible, is to take the that row from tableB and replace the one on tableA so it'll be modified.
I'm not sure if there's an easier way of doing that instead of using loops for setting the row's items.

I am using a DataGridView, which is bound to a dataset. There is a bindingNavigator as well.
when a user deletes a row by clicking "bindingNavigatorDeleteItem" button, I am trying to get the row being deleted.
private void bindingNavigatorDeleteItem_Click(object sender, EventArgs e)
{
int crow = gridEventType.CurrentCell.RowIndex;
but it returns the newly selected row AFTER deletion of a selected row.
so, If I have two rows
0
1
2
and I delete 2
crow is 1, not 2.
Am I missing something here?
2. How do I know whether certain rows are modified in datagridview?

I had to reinstall visual basic express edition 2008 on my pc.I deleted the old files from c dirve.I tried to install it from the ISO downloaded from the microsofts website but after i specify the drive (drive F) to install it on after about 2-3 minutes it says it failed to install it. [code] Does it have to be installed to drive c or something or is maybe the iso damaged? I just transferred it onto this pc and mounted the iso image using a program MagicIso which i used last time to install it.

View 2 RepliesI have an app where a user enters information on a ticket and that ticket is saved off to a file on a share.Later on, when the ticket is closed or resolved, the file is deleted.Pretty straightforward.The below code is used to achieve this but, and this is the odd part, I'm finding that sometimes the app does not write the file and other times it will not delete it.I've confirmed that the user is running the latest version, that the tool isn't in off line mode, that all the appropriate criteria are set to true before entering the routines. It works 99% of the time but every so often it doesn't create/delete the file and there are no errors thrown or anything.Going into this section of code, chkOffline is not checked, "GoNoGo" is set to "Go", "Type" is set to "Live" and all fields have been filled out on the form(and vetted).What's more, there are other actions earlier in the app/sub that rely on these same conditions and those actions are getting carried out.[code]
View 2 RepliesI want to create an application that will save the files being deleted from a flash drive into a part of the flash drive that acts as recycle bin. I want to capture the deletion event of windows so that I can copy the files marked as deleted. Is there a library that would notify my application if the delete event is being executed? If using FileSystemWatcher component, I cannot get the files being deleted because it will only notify after the file is deleted.

If i manualy delete one of these files wich are not realy important for the application then when i restart the application i see that somthing like an installer places the original file back again in the folder.
