You must give the focus to the control you want to send the keystrokes to. Using this method isn't recommended because it's not a completely reliable way to send keystrokes.
In order for it to work, you must give the application/control the focus, then send the keystrokes. But, in a multitasking environment like Windows, the focus can move from control to control and application to application at any time. This includes the time between when you set the focus and the time you send the keystrokes, even if SendKeys is the very next statement!

well ginving the text box focus works i only need it for a second. But it wipes out the entire contents of the textbox because of the focus it selects all.
so had to play a game and came up with
TextBox1.Focus()
SendKeys.Send("{right}")
SendKeys.Send("{backspace}")
works so I like it!

That's what I thought too... until it hit production! Out of 15,000 machines, some are garanteed to find that little second and mess it up for you.

I am writing this in VB.NET and testing it against Outlook 2003.
I have successfully added a new Menubar "myMenu"........ now I need to add 3 drop down options to it. "Option 1", "Option 2" and "Option 3". And I should be able to get to the click events for all the 3 options.
When I click "Option 1", it launches internet explorer (for example). Like I said, I am having a hard time trying to figure out how to add drop downs to the "myMenu" option that I added on the "Menu Bar".
Any and all help will be greatly appreciated!

Adding CommandBars to Outlook 2003 using C#

 In my code i have called a DLL which exports C++ functions which help me to read and retrieve data from different shapefiles(shapefile is a fileformat to store
non-topological geographic data)
The functions are in a while loop and the values got from the passed parameter are then stored in the sql database in ntext format(CLOBS).
Now this code works most for most ofshapefiles except a few shapfiles.
I get the following error:
An unhandled exception of type 'System.NullReferenceException'
occurred in final GUI.exe
Additional information: Object reference not set to an instance of an object.
I know what the error means but as it doesnt come for all the shapefile inputs i am unable to debug.
here's is my code:
While j < nver
Call vertice(i, j, k, start, x, y, nam)
strSQL = "Declare @ptr varbinary(16)" _
& "select @ptr =textptr(startpart) from " & nam & " where rec_no=" & i _
& "updatetext " & nam & ".startpart @ptr " & cnt0 & " 0 '" & ss & "'"
oCmd = New SqlClient.SqlCommand
With oCmd
.Connection = New SqlClient.SqlConnection(strConn)
.Connection.Open()
.CommandText = strSQL
oDR = .ExecuteReader()
End With
oDR.Close()
oCmd.Connection.Close()
j = j + 1
End While
Thanking in advansed.
PLEASE HELP

You haven't posted enough code to diagnose the error. What line does the exception occur? What objects does that line deal with? I bet you trying to use an object that you think is instantiated, but in fact, is not because of some failure above the line that threw the exception.
For example, what if your .ExecuteReader() method call succeeded, but the SQL it ran didn't return anything? Your code might be assuming that it returned valid data, but never checked it to be sure.

Hello there
I have build a project and with the help of vb.net Setup builder. I have built one setup. Now what I need is to run the Exe File after completing the installation as All other software do.
Can Any one guide me how to launch the Exe from setup wizard.
Best Regards

Since the .MSI setup project that comes with Visual Studio is a bare-bones, simplistic version, you'll either have to write a custom action that will launch the application or I highly recommend getting a more professional level packager like Wise for Windows Installer.

hi,
I am working on a project related to packet sniffer in JAVA. afer a lot of research I found that this is not possible in java. Java simply does not provide such low level facilities.
A developer suggested me of developing it in some other language and then passing the info to a java socket wherefrom I ca read the contents.
Another suggestion was to use some proxy to divert port 80 traffic to some other port and then read info from there.
I have found nothing on the latter. can someone help me with how to build a sniffer in VB.NET to be run as a background thread which can pass values to java.
I am running out of time as the deadline is approaching.
Please help me out.

Since you running two completely different execution environments, you can't run the VB.NET process as a background thread to the Java application. But, you can expose a VB.NET component as a COM object and import that functionality in Java through its COM interface.
Heath Stewart wrote a great article on just that subject here[^] on Code Project.

I have a class library and i have built the class library. I am using the DLL of that class library in a project. When i use the function provided by that dll in debug mode i am able to see the code written. how can i prevent this . is there some other way of making dll in .net so no one else can view the code once it is built.and i don't want to place it in the gac.

Do you mean you can see your original source code? Or do you mean you can see the IL code? Also, you only mention a debug version, why are you distributing this? Debug versions are compiled differently so that it is easy for a debugger to interpret what is happening with application should it go wrong. You should use the release version.
If you need to obfuscate the dll further there is a basic obfuscator that comes with Visual Studio.

when i am using the dll in aother project on the same machine then i can se the code. but when i use the dll on other machine then i can't. i'll be using the release version. i don't know much ablout obfuscate, just that it helps in protecting intellectual Property . can u give me an example on how to protect my dll by obfuscation?

That is because you are using the debug version. I've said already that it contains extra information in it to assist debuggers to show exactly where errors are. Some of that information is the location with in the source code files of the code that it is currently running.

In the tools menu in Visual Studio you will have Dotfusticator Community Edition which is a basic obfuscation tool.

but i don't know how to use it (dotfuscator). is there any sample or tutorial on how to use it.

Has it occured to you to read the help files first? Load Dofusticator Community Edition, and go to the help menu. You have to learn to at least attempt to read the documentation before whining that you don't know how to use something. Then at least when you come to say that you don't know how to do something you can explain what you tried to do, what you thought the documentation meant and so on.

I have create a datagrid and placed a tablesyle within it, and have filled that with Data Grid TextBox Columns. I have been able to get my datagird to show tablesyles, now I'm trying to get the my datagird to automatically open my tablesytle with no luck is there anyway that this can be done through code or properties?
Anyhelp would be great
Thanks

Without seeing your code, it's impossible to tell you what you've missed. Part of a tablestyle is supplying the name of the data column that it's supposed to display for. But, like I said, with out the code...
