Your question seems to be a bit jumbled. You have created a borderless form that allows interaction (minimize, maximize, close) through custom controls. Now, based on what I understand, can you make the question a bit more clear?

This can be done in a variety of ways. Image background, panel with 3D styles, custom control form borders, etc.

You should make clear what you want to do. what is this picImage.
Is it a picturebox or an image control.

sarfarazaliqureshi11-Nov-08 8:04

11-Nov-08 8:04

PIcimage is a picturebox and clrr = red Color,clrg = green color,clrb=blue......

Thomas Stockwell11-Nov-08 2:49

I am assuming that the picImage is a Bitmap object (at least when transferred to VB.NET).

You should be able to use the SetPixel method:

picImage.SetPixel(r,c,new Color(clrr,clrg,clrb));

sarfarazaliqureshi11-Nov-08 8:09

11-Nov-08 8:09

Dear this line of code giving me this error...

picImage.SetPixel(r,c,new Color(clrr,clrg,clrb));

Error is:
"Type System.drawing.color has no constructs"

and picimage is a bitmap........

Thomas Stockwell11-Nov-08 8:17

11-Nov-08 8:17

Oops,

Color.FromARGB(clrr,clrg,clrb)

I am not too familiar with terminal usage, but at first glance I would say emulation. I believe terminal is basically a command prompt window. Simply create a new terminal with Process.Start, and redirect the input and output to your application. Input would be the commands that you type to get the scale information, output would be what the application responds with that would be sent to your application.

[Edit:Look into the startup info properties for the Process class.]

Google for a "tcp/ip terminal emulation library" you can use. It's either that or you're going to have to write one yourself using the System.Net namespace.

write a application for tcp-client, then connect to your terminal IP,Port
You can get the data on your tcp-client socket.

Hello everyone...

I have developed a windows application using vb.net in visual studio2005.The backend was sql server2000.Now when i try to run the exe file of the project in another machine which has .net framework installed in it, i am getting the following error.

'System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)'

Even though there is SQL server2005 packaged with visual studio 2005, i created the database in sqlserver 2000.I tried changing the prerequisities of the project deployment by including sqlserver2005 in prerequisities list...but that too isn't working....Now what should i do to run the project in other machine...........plz could anyone help me out................. Confused | :confused:

Hi

you seem to be having connection issue, your app cannot access the sql db.

1.
you connectionstring property may be incorrect....

2.
check to see if sql server accepts incomming connections
use the sql2005 connection manager and enable the various options...

hope this helps

There is no problem with connection string bcoz the application has no problems in execution in visual studio ide. the problem happens wen the exe file of the application is executed in another machine. i have tried enabling remote connections of sqlserver2005 in configuration manager. one thing to be noted is that the datatbase is being created in sqlserver2000.

The sql2000 db should not be the cause of the error.
i have used applications that was created in sql2000 and attached it to sql2005 and works fine from other pcs.

System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)'

once again make sure you named pipe protocol is enabled

ps. did you restart the sql 2005 service after enabling all protocols?

thanks

pravimarrs11-Nov-08 19:02

11-Nov-08 19:02

Sir
I have restarted sqlservice after enabling the protocols but the same result again.I have made connection only to sqlserver 2000,i didn't use sql2005 then why is that the error related to remote connection setting of sql2005.

thanks.......

That doesn't mean anything. The connection string can still work for you on your machine and fail on others because of the connection string. This has to do with most people blindly using the Trusted Connection option without knowing how it works.

Is SQL Server 2005 installed on the same machine as the one the application is installed?? Is SQL Server 2005 configured to accept connections on something other than just Named Pipes??

Hi,

it could also probably be a port conflict between sql200/5, the default tcp/ip (IPAll) port is set to 1433,
you might have to change this to 1434 or something and specify this on you connectionstring .

ps. lets have a look at you connectionstring!

thanks

pravimarrs11-Nov-08 21:25

11-Nov-08 21:25

connectionstring: Data Source=hari;Initial Catalog=apollodb;Integrated Security=True;Pooling=False

provider: .NET Framework Data Provider for SQL Server

state :open

thanks for the reply.......
