A hashtable, or if the numbers are sequential ( i.e. 1,2,3,4,5,6 ), an array.

how to start to write d coding for voice recognition.. anyone have any idea?
|
|
|

Start by not using VB.NET, I'd use C++ for this, for sure.
Next, if your first approach is to ask such a vague question in a forum, wait a few years and try again.
Microsoft has a speech recognition SDK if you just want to add it to an app you're working on. I have no idea how good it is.

Hi,
I have an input form with quite a few textboxes. When I tab to one of these textboxes I want it to highlight the complete data and not just put the cursor at the end of the data. This means that the user can overtype the data instead of deleting and then typing.
Any help appreciated

Give this a try:
To handle one text box:
<br />
Private Sub TextBox1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Enter<br />
'select all text in the text box<br />
TextBox1.SelectAll()<br />
End Sub<br />
To handle multiple text boxes:
<br />
Private Sub TextBox1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Enter, TextBox2.Enter, TextBox3.Enter<br />
Ctype(sender,TextBox).SelectAll()<br />
End Sub<br />
Note: Text is selected when the user tabs into the Textbox

Hi,
We have VB6 application up and running having SQL 2k as database. It has about 50 and more user using at pick hrs.
Now the problem is, sometime, few user got error message and kicked off from the application. I analyze windows eventlog and found that type of error is DrWatson and some exception thrown for multibytetowidchar kind of.
I really don't have any idea what happening here. If anybody have any little idea abt this I can give descriptive and exact explaination to them and will discuss further.
Thanks

Without the EXACT error message, it's not even possible to do a meaning ful search on it. Since we have no idea what your code is even doing at the time of the problem and MultiByteToWideChar is part of the Win32 and is used inside all VB6 apps extensively, this could be, literally, caused by anything in your app.

Error message on User's screen
"Child.exe has generted erros and will be closed by Windows. You will need to restart the program. An error log is being create."
Error message in error log - error log retrive form event viewer of administrative tool.
Type – Information
Source – DrWatson
Description - The application, , generated an application error The error occurred on 07/19/2005 @ 08:20:47.979 The exception generated was c0000005 at address 7C5B89AE (MultiByteToWideChar)
Can you help me out with this information.
If you want something more / else... write me up.
I am trying to find out the pattern of the error.
Let hope for the best.

There's just not enough information to pin this down, but, it could be caused by a badly formed SQL statement. If your code is using string concatenation to build SQL queries, like
Dim mySQLStatement As String
mySQLStatement = "SELECT * FROM sometable WHERE field1=" & somevariable & " AND field2 Like '" & something & "'"
you'll problably have problems that you can't trace down.
You might also try upgrading the MDAC to the latest version.
This is one of those problems that is very generic in nature and is not going to be solved easily. If you don't have to source code for the app, you're pretty much out of luck.

We got the source code at last...
Now what would be your approach to trace down this proble.
What you suggest to eliminate this error?
Just let you know, that this problem is not consistant and pops up in few forms till now. After kicking out from the application, user do the same thing again, it will work fine.

Put in instrumentation code to log what is going on by follow what functions are being called with what parameters, what return values are coming back from functions, and sql queries.
I didn't say this would be easy...

Hi All,
I have a requirement for shading the backcolor of certain rows of the Datagrid.
Lets assume my table has 4 rows in it. I want to display the alternate rows in different colours and if two consecutive rows is grouped for some reason they need to show the same color. (Can't Use Datagrid's Alternatebackcolor and backcolor).
Case 1
Row 1 & 3 backcolor as Pale green
Row 2 & 4 backcolor as Dark green ( Easy with the above said properties)
Case 2
Row 1 backcolor as Pale green
Rows 2 & 3 backcolor as Dark green
Row 4 backcolor as Pale green
Tried loads of samples but can't achieve these 2 cases with any of them.
can someone help ?
Thanks

I Tried this sample yesterday and this doesn't solve my first case wherein i have to display alternate colors for each layer.
Anyway thanks for your help.

You don't connecto to the machine, you connect to a server running on it. What are you trying to connect to?

Thanks for the reply progload,
My problem is nobody seems to know how this works here.
i have been asked to test the connection to the AS400 using vb.net
i have the server ip address, i have the user id and password to log into the as400. what or rather how would i test the connection then.
is it possible for a detailed explanation.
i need to display the file contents from a specified library into a data grid, tell me or give me an example.
thanx in advance.

I’m building an application that is used to manage project data such as CAD files, images, etc.
At the beginning of a project, a ‘rough’ directory structure that holds project information is created. This structure changes throughout the process of working on the project. The changes include: File/Folder renaming, deletion, adding and moving.
I’m trying to think of a user friendly interface where these file/folder operations can take place. I’m thinking of something similar to a Windows Explorer type window but with the ability to move folders up and down the tree. Or, even better, drag a folder to another location.
Has anybody ever seen any examples similar to this? Any ideas or suggestions??
Thanks
Brad
