This allows you to select text inside the textbox. By Select I mean highlighted as you do with a mouse by clicking and dragging.

'Fill the text box with some chars
textbox1.Text = "ABCDEFGHIJ"

'This line will highlight the first 3 characters 
'in the text box
textbox1.Select(0,3)

It is located in the help here:

Thanks for the info. It would be nice if you could access the same controls M$ uses. The XP Style password box displays a ballon tip when you turn CAPS Lock on and things like that.

MSI VB Custom Action

I add an application to the …\Windows\CurrentVersion\Run\ folder in the registry during an install, and would like to start the application immediately.

The first solution would be to start the application manually from within a Visual Basic Script Custom Action, and the second solution would be to force a system reboot.
Either would be acceptable.
But I can’t seem to figure out how to set the “REBOOT” property to “Force” or to run an application in my Visual Basic script.

Any help would be good.

Thank you in advance.

To launch an external app try WshShell.Run or WshShell.Exec and supply it with the exact same command line that you put into the Run key.

You can find more info on the WshShell.Run command here:

I am not sure how to do this if you are referring to something drawn onto the form via GDI.

A few more details please? Confused | :confused:

is one project a component and another an exe maybe?

Anonymous3-Jun-03 7:34

The 2 projects are independent.

Ok.... and by 'calling' what exactly do you mean?

- Do you want the first app to start the second app? You can simply shell out and start the second app fronm the first.

- Do you want to pass data back and fourth between them? Theer are several ays to do this... remoting, sockets, shared memory, shared files, etc...

Try looking for examples related to System.Net / System.Net.Sockets Namespaces. I seem to recall that I saw an example of this on DotNetJunkies.com or c-sharpcorner.com; even though the example was in C#, it could be done fairly easily in VB.NET.

DataSet Changes?

I have a DataSet that gets it's data from a stored procedure. I then use that dataset to populate a datagrid. When the user makes changes to the datagrid or adds new rows, how can I update the database table with the affected rows? Is there a way to tell which rows in a dataset have been changed or added?

just use the update method of the adapter you used:

Adapter.Update(ds)

Just make sure you have created the commands neccesary for the operations (insert, delete, update)

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.
