I'm teaching myself vb.net again after being out of school for a few years. My problem is probably simple although I don't know the correct terminology so it makes it hard to search for a solution. I am making a simple game with picture boxes. I created the variable YellowDrop which is a string. It concatenates a few things to create "Yellow6x1" for example. This is a picture box. I now need the command equivalent to yellow6x1.visible. I cannot just do yellowdrop.visible because visible is not a part of string. Can someone point me in the correct direction? Thank you.
If cbColor.Text = "Yellow" Then
For RowLoop = 6 To txtRow.Text Step -1
YellowDrop = ("Yellow" & (RowLoop) & "x" & (txtColumn.Text))
'****Here is where I need a command that would act like YellowDrop.visible****
Next
End If

I think i'm getting closer by making yellowdrop a picturebox... but not quite there.
Dim RowLoop As Integer
Dim YellowDrop As PictureBox
If cbColor.Text = "Yellow" Then
For RowLoop = 6 To txtRow.Text Step -1
YellowDrop.Name = ("Yellow" & (RowLoop) & "x" & (txtColumn.Text))
YellowDrop.Visible = True
Next
End If

You will need to use 'reflection' to accomplish what you want to do.

The best bet would probably be to make an array of controls and then index into that array. Depending on your configuration it may make sense to have a two dimension array.

Hello,
My application consists of an EXE acting as a main menu. Each menu item opens an app that sits in 1-many dlls. Each application has the ability to communicate in one way or another via a object handler that I called the HUB. They all have shared memory as well as shared objects they can access to get things like security and user information, etc.
Problem #1)
All of these apps are started via the main thread and if one of the apps dies, it has the potential of killing everything on the thread. I have added appropriate onthreadexception and unhandled exception error handling but again...but depending on the error, recovery of the other apps may or not be consistent.
Problem #2)
Each one of these apps has the possibility of showing a dialog box (msgbox or one of my own). Because each app was started on the main thread...all the other apps are locked until that one app shutsdown the dialogbox because as you know the dialogbox blocks execution.
I would appreciate any design tips on how you get around these issues and how you handle a multiple application suite of software that communicates with each other. I'm open to redesigning if it takes that effort to straighten these two issues out...
Thank you 
Nathan

Are these truely "separate apps" or can you redesign it to fit into a Muli-Document Interface model ?
|
|
|
|
|
they are seperate apps sharing and reusing "global" components
mdi will not fix the 2 problems...all the apps must be functional at the same time...and putting them in an mdi will not meet user requirement...

Hi all...
I want to know that how to define column size of datagridview.
By default all columns are of same size.I want to change size of columns so that at runtime it will display different fields of different size.
Thanks...
Gagan.

This has nothing whatsoever to do with database design.
Right click on your datagridview, select Edit Columns and adjust the Width property to what you need it to be.

I want to know that what should I do for providing an interface between my application for communication,i.e. what should I prefer, either creating a web interface or creating sockets.
If you have any example then please send it to me.

It all depends on what the application is.
If you want it to be available on ANY PC without needing to install a client on the remote PC's then a web application is best. However a basic client/server type application is probably easier and faster to create.
Simply create a project and add the Winsock.dll to it.
You can find lots of articles on using Winsock in client/server applications just by Google'ing it.
I have created a vast application suite that has a server and several different clients connect to it to send alarm messages and the server dispatches alarm notifications to any client that should get it. Another easy one to make is a simple client/server based chat program.
Hope this helps!

AFAIK, the width depends on the printer setup parameters you have specified in the report designer.

I want an expandable gridview which displays child rows.
I have already implemented it using a parent and child gridviews concept.by having child grid inside itemtemplate column within div tag and display or hide it using javascript function. this affects performance.If i have 20 records displayed it will 20 child gridviews.
can any one tell me a approach which will not affect performance as well as do not postback.
Thanks in advance.

You're looking for the ASP.NET forum[^].
Youre question has nothing to do with VB.NET at all. But, you may also want to look into third party grid controls if you don't want to put the time into creating your own grid.

Google for something like a "Contact Manager" application. That's about as close as you're going to get to what you described. You'll, of course, have to modify it to your own needs.

ambiuous namespace means your application namespace name or any two namespace in your application have the similler name. So try to use the full path of the name space. It will work.
|
|
|
|

Let me clear up the other guys explanation.
It means you have the same class name defined in two different namespaces you're importing. You could have given a class in your code the same name as a class that Microsoft wrote in the .NET Framework.
