How can you generate random colors from the system.drawing.color structure?
i.e.
Color.Red
Color.Blue
Color.Green etc.

Try the MSChart Control which comes with VB 6.0

I have an empty table I set up as a Master table template. How can I copy this table and give it a new name using SQL? I have to create a new table each day so I just want to copy this template table I have.
|
|
|
|
|
select * into new_table from old_table where 1 = 0
This will copy the basic structure, but it will not create indexes, PK, constraints, etc.

Is there no way to do a SQL command like CREATE TABLE or something to copy this table?
|
|
|
|

Something like a "COPY TABLE STRUCTURE"?
No, probably because it's not a good practice to spread your data through several small physical tables. Your physical database design should be decoupled from the logical design.

Oh boy... Your DB admin will love that 
Just use one table and add a date of entry column. Its soooooo much simpler.

Do you know where I can get modules to print bar codes ?

Look on SourceForge[^]. I saw a barcode thing there recently ("BarCode .NET" or something like that).

How can i use concurrency control using vb.net.I have used sqlcommand,sqlconnection and sqldatareader(No Dataset) to access data from database in my project.And multiple user can access and modify data ,so how can i use lock and cursor to maintain consistency in database.
|
|
|
|
|
|
I will be glad to have a VB.NET code snippet to implement Concurency control when data inserted or updated on the database through command/datareader objects of VB.NET.
|
|
|
|
|
I apologize for the brevity of my response -- you can achieve concurrency control using transactions in ADO.NET with the SqlTransaction class (see MSDN[^] for more details).
However, the following two examples might be more specific to the issue you are attempting to resolve:
MSDN Data Concurrency[^]
Data Concurrency Exception Handling[^]

I was wondering where I could find information on automating VB with Excel, outputting data to a spreadsheet. I'm trying to make a punch in and punch out type setup that keeps track of punches on an Excel spread sheet. Any info would be helpful.
Thank you

Read the VBA help in Office..
Automating Excel in VB6 is very similar to it.

You can try using the SendKeys function (Lookup MSDN)
You can send a specific key sequence using SendKeys (Eg Alt+H or Alt+F4)

I created my first web service and accessing it from IE on the local machine works great. But when I try to access from another computer on the network I can see the definitions but cannot execute any of the functions? It says they are only avaiable to the local machine. How do I make it available for any machine?
|
|
|
|

Here Is The Answer:
Your problem lies in your machine.config file which will most likely
be in the following directory:
C:\WINNT\Microsoft.NET\Framework\v1.1.4322\CONFIG
The problem is that .NET 1.1 ships with HttpPost and HttpGet turned
off. look for the following tags:
<webservices>
<protocols>
<add name="HttpSoap1.2">
<add name="HttpSoap">
<add name="HttpPostLocalhost">
<add name="Documentation">
You will notice that HttpPost and HttpGet are commented out. Uncomment
them and it should fix your problem.
Thanks,
Kenton Smeltzer
