You didn't mention which version of VB, so I'll assume VB.NET. First, you create a Graphics object from the PictureBox's CreateGreaphics method. Then you can use the Graphics object to draw on the PictureBox. The PictureBox itself doesn't have any drawing methods. See the documentation on the Graphics class for explanations and examples. There is just way too much information to post here.

OK. The VB6 PictureBox docs start here[^]. You can use the Print method to display text in the picturebox anywhere you want. Just remember to set the PictureBox AutoRedraw property to True first.

Dim myVar(10, 10, 10) As Long
Dim myVar(10) As Long
Dim myVar2() As Long
VB.NET only:
Dim myVar As Array = Array.CreateInstance(GetType(Integer), 10)
Dim myVar As Array = Array.CreateInstance(GetType(Integer), 10, 10)

I am developing an asp.net application using vb. I have a hyperlink control in my repeater template and I am not able to dynamically create parameters for its querystring. The parameter is the same value as the text. The reason I am using a hyperlink against a linkbutton is that I want the target window to be a popup.
<asp:HyperLink NavigateUrl="javascript:var w =window.open('Details.aspx?Name=<b>(what do I do here)</b>',null,'width=400,height=400,location=no')"
Text = <%# DataBinder.Eval(CType(Container, RepeaterItem).DataItem, "Name") %> Runat="server" ID="Hyperlink1"></asp:HyperLink>

There is no such thing as a TSR in Windows. THe closet match is a Windows Service.
In VB.NET, easy, just start a Windows Service project.

Why? It's already been done and won't take you at least 6 months to write it if you go buy PCAnywhere or something equivelent. Microsoft has their's, called RemoteDesktop...
You'll be writing 2 seperate apps to do this. The server will run on the machine you want to control, while the client will run locally. You'll be P/Invoking ALOT of Windows API functions on the server to get the screen image, follow the mouse and keyboard events, and post new keyboard and mouse events coming from the client.
This kind of project will take an average of 6 months to develop. How much do you get paid in 6 months? Compare that to the off-the-shelf cost of PCAnywhere...

Hi,
I need help... How can I limit the rows in one field into 1 row only so that whenever I save something using VB, the content of that row would just be replaced by a new one. For example: in a textbox, if I enter a name and click save, the name that I typed would be saved on a database. If I enter a new name, the name that I entered before will just be replaced with a new one.
I used this code and I bind my richtextbox with a data control and it was running ok. But I still would like to ask for suggestions... Thanks...
Public gadocon As adodb.Connection
Public gadorset As adodb.Recordset
Private Sub cmdadd_Click()
rtbox.Locked = False
Set gadocon = New adodb.Connection
Set gadorset = New adodb.Recordset
gadocon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Documents and Settings\gen\Desktop\TRIAL 4 THESIS\transfering form2form code\dbtext.mdb"
gadorset.Open "Table1", gadocon, adOpenKeyset, adLockOptimistic
gadorset.AddNew

You can't limit the number of rows in a table. In the past, when I've needed something like that it was usually because it was a setting I needed to store in the database. I created a SystemRegistry table where there were two fields, a keyname and a value (stored as nvarchar). That way you can store the name as somthing like this:
keyname value
frmMain\Firstname Mike
frmMain\Lastname Vernon
A bit of a poor example, but if you need to store system settings acrossed a clustered web application it becomes pretty convenient. If you needed to bind these fields, you could make a class that reads these settings and holds onto them and bind your controls to the class and not directly to the database.

I am trying to learn how to search through a hard drive and look for a file extension, is there a tutorial that has been written that shows how to do this?
I have a form with a button, and a checkedlist box. I would like to have the program search though a hard disk and output all the files that have the inputted extension.
How is this done? What about directories that have access denied error message comes up like c:\system volume information? How do I skip that directory?

I just noticed that when I write an entry into the Windows event log using one of the various overloaded WriteEntry methods I always get the following text below my description:

 Grrrrr, I don;t want to send my users to the MS website....
Any ideas?

I want to backward format a date to the number. Does anyone know how to do that? Like take 01/01/2003 and get the number value.
Thanks

What number value? Are your talking about some kind of serial number representing a date? Like how many seconds from a base date, like Jan 1, 1970?

When you register the dll and copy the registered .dll to another directory
generates serious problem. even unregister both .dll and reregister the original dll again won't solve the problem. Probably i have to work with registry and delete some key( i am not sure which keys to delete).
another option for this kinda problem. I have listed all dll that have the same dll in VB's reference library.
Thanks in advance.

You can't register the same .DLL multiple times. This is because the registration is based on the GUID's in the .DLL, not the location of the .DLL. Unregistering it and then reregistering the .DLL will only update the location of where the .DLL can be found when it's needed.

You might want to provide a description of the problem itself. Maybe there is another cause you haven't thought of, besides a registration issue...

What I need to do was just clean up the registry and reregister the dll
like you said
"Unregistering it and then reregistering the .DLL "
is probably important.
Thanks for the tip.
