Ummm....What? Do you mean you need the Desktop and the Start bar to show up inside your app? Not going to happen...

Hi guys!
need some help...
i have created a window service which inserts some values in sql server2005 after every 30 min after chacking some details. the service is running fine but it takes the CPU usage to 100 percent while it is starting..
i m using a while loop to check the current time and start the timer as the data insertion must be done at exact time like 12:00 pm, 12:30 pm; 1 pm and so on.
the loop goes on iterating till the current system is equal to any time which is round figure.
i think the problem is in that only but not finding that .
can any one help me ... what i m missing..

There's your problem. You're loop is not giving control of the CPU back to the rest of the system. The startup code in a service is expected to launch a seperate thread to do its processing, not block itself in an endless loop.
You don't need to be checking the current time every couple of milliseconds. All you need to do is start a Threading.Timer that calls a function once a second. In that Timer Elapsed handler, you check for the current time, and if needed, do your processing, then reset the Timer. Using this method, your CPU usage should fall to just about 0.

Hi,
I tried to install visual studio tools for office now for about two hours and I have failed miserably.
What I did was
1 Installed visual studio 2005
2 Installed office (with the .Net things for word, excel, outlook etc.)
3 Installed vstor.exe
Now if I understand things correctly this is supposed to be enough. Also this would give me some office options under the new project tab in Visual studio but no. And when I tried to open a sample project visual studio was kind enough to inform me that it did not have all required components installed.
So does any one know what I need to do? A quick (and clear) response would be much appreciated since I’m about to run a screwdriver through my hard drive.

I suppose you use vb and not vb.net..
Start you vb IDE - Select ActiveX dll - Write down the functions, you want to expose. Function should be declared as Public if you need to make a call.
Select make projectname.dll from file menu.
How to register
regsvr32 "dllpath\dllname.dll"
How to unregister
regsvr32 "dllpath\dllname.dll" /u
You need to register in w2k or xp, if it is not machine where you have developed it.

Hi,
Is this possible for a listbox?
When the listitems of the listbox are selected and right-clicked, a context menu appears.
Then, when the user right clicks on the empty space inside the listbox, the context menu will not appear even though an item is still selected.
If possible, what listbox event is used?

Hi,
U need to create menu on the form and make it invisible. Then on Mouse Down event of listbox check the value of button.
in this way
Private Sub List1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = vbPopupMenuRightButton Then
Me.PopupMenu Me.file, vbPopupMenuCenterAlign
End If
End Sub

Hi All!
How do I associate the documents I save using my program to the program itself? Can't seem to do it. I right click the file and then open with... then I click on the vb.net program exe file that I have created but nothing seems to happen...
Thanks for any reply!

What do you mean "nothing happens"?? Nothing happens what you double click the document? Does your app launch, but no document is loaded??

Hello Dave,
When I try to open the document that I saved using my program, the "windows cannot open this file" dialog pops up. It does not know which program to use to open up my document. But I can actually open the document only when I open through the program.

It sounds like the association is messed up. Open Explorer and click on the Tools menu, Folder Options. Click on the File Types tab. Find your file extension in the list and click on it. Then click on the Advanced button. You should have an open item in the Actions box. Click that, then click Edit. The command line under Application used to perform action: box should look something like this (with the quotes!):
"C:\Program Files\someFolder\myApp.exe" "%1"
If the quotes are not there, the file paths will not get processed correctly and your app will get a list of command-line parameters like this:
myApp.exe C:\Documents and Settings\userId\File To Open.txt
The list of 5 parameters will look like this:
C:\Documents
and
Settings\userId\File
To
Open.txt
Depending on how you coded your app, the filename it'll try to open will be C:\Documents.

I have actually done what you said before. I am unable to find my file extension in the list. I added manually and after that went to the advance section and configured the actions myself. I also change the icon. After I click OK I got back to the Folder option dialog. When I click the advance tab again, everything I edited and configured will haf disappeared...

I have no idea what you're doing wrong. Other than when you go back into the list, it's resorted alphabetically. You could attempt to create a New association and try to use the same extension and see what happens.
You might also want to try it using an admin account.

After reading your post again, it would seem that your app is not written to handle command-line arguments. You might want to read up on the <a href="http://msdn2.microsoft.com/en-us/library/system.environment.getcommandlineargs.aspx" rel="nofollow">Environment.GetCommandLineArgs</a>[<a href="http://msdn2.microsoft.com/en-us/library/system.environment.getcommandlineargs.aspx" target="_blank" rel="nofollow" title="New Window">^</a>] method.
When you launch a documnet in the way you described, the associated process (or the one you pick in that dialog) is launched using a command line similar to:
C:\Program Files\SomeFolder\MyApp.exe C:\Path\To\SomeDocument.ext

I'm using the RemoveTableRow method in the following code, which updates the dataset, however it doesn't ever update the database via the data adapter. Any one have any idea why? Much appreciative
(code generalized)
'Module level declaration
Dim mdrRow As DataSet.TableRow
'Retrieve datarow from dataset
mdrRow = DataSet.Table.FindByTableID(txtfield.Text)
with mdrRow
txtfield1.text = .field1
etc
end with
'Activated by a btnDelete
Dataset.Table.RemoveTableRow(mdrRow)
SQLDataAdapter.Update(DataSet)
DataSet.AcceptChanges()
When I attempt to retrieve from the dataset the row is no longer there, however it never updates to the database, so when the program terminates and the dataset is refilled the row is then back.

Perhaps you never really deleted the row? Check the RowState of the row in question before you attempt to write the data back to the database with the Update call. I get the feeling your code never really returns a DataRow object when it calls FindByTableID. There's no such method in the .NET Framework, so you had to write it somewhere. ...Or is this not a Copy and Paste version of your code???

Dave,
First, I thank you for your response.
Second, forgive me, I am new at VB.Net programming. I believe the row has to be deleted in the dataset. I'm using the FindByTableID method to populate a form when the program is first loaded, which also assigns the TableRow to the variable "mdrRow". At this time the row is retrieved to the form (successfully). If then, I click on the delete button the code DataSet.Table.RemoveTableRow(mdrRow) is then fired. At that point, if I attempt to retrieve that record using, again, the FindByTableID method the record is no longer found, which leaves me to believe it is indeed being removed from the dataset. However, when I close the program and then rerun it, thus refilling the dataset at form_load the record is now there (in the dataset) again. Can you tell me an example of how I would implement the RowState in this scenario, as I'm unfamiliar with that method.
Maybe my theory on this is all wrong. If you would like, and I would tremendously appreciate it, I can send you the exact code offline.

Each DataRow object has a RowState property. All you have to do is set a breakpoint on the code where you're deleting the Row, Dataset.Table.RemoveTableRow(mdrRow), then look at the mdrRow object in the Watch window. Find the RowState property, then watch what happens to it when you hit F10 to single step through the code and run that one statement. If the RowState doesn't change to something like Deleted, the Adapter.Update statement won't know that is has to call the SQL delete statement for that row.

Not sure if I'm doing this correctly;
I inserted a Breakpoint on the dataset.table.removetablerow(mdrRow) statement, then when I run the program a messagebox is displayed that states "There is no source code available for the current location." I then have a choice to look at the disassembly? I do see the Watch area but there is no name, values or types. Thank You.

Try setting the breakpoint to the first line at the beginning of the Sub where this code is, then stepping through it one line at a time.
