I recently switched to V.Studio 2008 and using VB. I can not find in the data toolbox the connection and data adapters. Should I do something else to make this appear so I can drag them in my form.
I have created a custom designer (PannelloSfondoDesigner) for my custom control, a background panel (PannelloSfondo).

It works, I click the little arrow, the context menu appears:I click the menu item, the event is fired, the control is docked:but the menu description is not updated or refreshed (it should show "Undock from parent container"). Then if I click outside the control to deselect it and then I click back on the arrow to show the menu, the right menu item is displayed:How do I refresh the menu items?
What must I add to the deployment project so that when the user clicks Start>All Programs>My icon, my program runs. Now the explorer comes up pointing to the application directory.
I have a simple scraper. It works on some websites, but on some there is this Error:

It is occuring at "Dim htmlresults As String = Urlcontents.ReadToEnd()".

I have a problem with Oledb connection when I am trying to open an Excel spreadsheet:
[code]...
This piece of code works well on one computer, but on another the IMEX=1 doesn't seem to work, and the Jet seems to read the first few rows of the Excel spreadsheet that are numeric and decides that the whole spreadsheet is numeric, so it ignores some String values later in the sheet.
I made context menu for UltrawinGrid, when i click right mouse button then the context menu open. This is the code that I use for my menu:
Private Sub ShowContextMenu(ByVal mousePoint As Point) Dim cMenu As ContextMenu = New ContextMenu cMenu.MenuItems.Add("Delete") cMenu.MenuItems.Add("Copy") cMenu.MenuItems.Add("Paste") cMenu.Show(UltraGrid1, mousePoint) End Sub
Now I want when I click on context menu item, for example delete, to call function that gone do something, how i can do this? How I can make connection between menu items and functions?
This will happen at random, and I can always just catch the error and re-establish connection to the server, but I am confused as to why. When doing lots of inserting into the sql server, I only establish one connection that is public, instead of many little connections. I had my doubts on a public sql connection, but it's been running great, and I've seen no problems until this morning. Again, this random moment I hit an error that stated, sql connection state is broken. Is it bad practice to just accept this error, and when it happens, re-establish the connection?
In my winform app in VB.NET I want to use the localization option. But i have a few questions/problems. I'm using a menu strip to select an other language. But it seems that is doesn't change my menustip text to my selected language. It does change my labels, buttons, and textboxes but menu strips don't seem to change when I choose another language. Also is it possible to get those resx files such as MyForm.fr-FR.resx compiled so it isn't an external file outside my app? Or to get those files in an Language folder at the same location of my app, so i don't have all those fr-FR & nl-Nl folders in the same location as my program?
Whenever I have an error, the program doesn't crash. It just stop executing code. The error message goes to the debug window (which I can't see until I end the program). If I have a button for example I can still click this and execute the code inside it.
I never thought I'd be asking this, but how do I make my programs crash again?
I'm using VB .Net 2008. I have been experiencing a wierd problem with my FileSystemWatcher that I haven't been able to resolve for the past few days. The watcher only catches the first event. The watcher is enabled via EnableRaisingEvents. I'm not sure why it quits. I was getting an ContextSwitchDeadlock error, so I placed <MTAThread> before the sub to switch to multiple threading. The errors stopped, but the FileSystemWatcher doesn't activate after the first event. Has anyone experienced this before? How do I fix this? [Code]
I am trying to add a registry key in to the file "MyApp" which doesn't yet exist in the registry key directory, when I try and write this key however I get an error from the debug console telling me the "NullReference was unhanded". If I go and manually make this folder it works brilliantly, I thought that this code would make the folder as well?
this is strange, I've got a macro with an array containing several registry keys. And I want to insert the values of these into predefined bookmarks in a Word document. This works great if the key is there, but if it isn't, I want the code to skip that and continue trying the next one in the array. I've got the code that looks like this:
I have creating timekeeping application, I was used drag and drop for my datagridview. During build I can add, edit and delete records. But when I published and run there was an error saying (see below). [Code] When JIT debugging is enabled, any unhandled exception, will be sent to the JIT debugger registered on the computer, rather than be handled by this dialog box.
Mine is a simple conexion problem but I dont understands what's happening I have another form in the same project which has no problems at all, I desided to create a form to use it as a base form named plantillav only to duplicate forms and intance the others from that one I put it's Modifiers Property = Protected in ortder to modify property values in the other ones I don't know if the process generated a failure.
I created the following strconn:

This table was exported from phpmyadmin (wamp) so it means is created and even with registers inserted directly from console, the problem is when I send from the application, with the following error that indicates that the name of the field doesn't exist or is not well written; Unknown column 'code_empleado' in 'field list'.
I get this error when trying to populate a DataGridView.The last sentence of the error text says to handle the DataError event but I'm not sure how to do that. A Try...Catch doesn't work.
I have this function I put together with help online and it works just fine until the program runs over night. I don't think it is night time that is the problem, just the long run time. I take bitmaps and place text on them then convert them to icons so that the image can be used on the system tray.
If I use IE I can visit the website I want and click the 'Next' button and life is good. If I open that same website using the webBrowser control and click the 'Next button I get a javascript error message.I'm not doing anything in the code to manipulate the website. My goal, eventually, is to have some level of automation; but at this point, I get the javascript error and a pop-up and it screws everything else.
I have written a sub routine for a Save>Menu option for a MDI Text Editor, see my code below
Private Sub SaveToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveToolStripMenuItem.Click Dim f As Form2
[Code]....
Now if I take out the ( I get yet another error which states
"Argument not specified for perameter "File" of public sub WriteAllText(File as string, text as string, append as boolean)
All I want is when the user clicks the save menu item the document either saves the changes made to the current document or the save as routine is involked.
