OK, you asked two different things here.

How are you drawing it now ? If you're using a picture box, you can set it's display mode to resize the image to fit.

A generic error occurred in GDI+.

1 - if you want people to answer you, don't keep deleting your posts, it makes the forums messy

2 - OK, where do you want to get this data set from, if not a database ? I can see now that we had 0 chance of understanding what you want from the original question, but I'm no closer to being certain what you mean.

You want to have 10 different conditions, but not all at the same time. Like 10 different searches ? Do you mean you want an OR search on different columns ? In the database ?

Hi Rushiraj,

On which line does the error occur? If it's the FromStream line, I too have experienced this error - From what I can figure it's due to corrupt data being in the stream, which without seeing how you are filling streamImage I can't tell. Slap in a couple of breakpoints and perform some checks to see if you are receiving all the data that you sent - I'm experiencing the problem of not receiving all data,and have just posted.

Regards,

Satips.

hi
error occurs at this line
bmp.Save("c:\\test.jpg", ImageFormat.Jpeg);

and data is correct.

If I do only

Bitmap b = new Bitmap(32, 32);
b.Save("c:\\test.bmp", ImageFormat.Bmp);

it is also giving same error.
I think it should create blank bmp.

Thanks,
Rushiraj

'A generic error occured' usually means the error is within the underlying, Win32 stuff.

One thing that will generate this error, is if you have a bitmap somewhere that was opened from this path, as it will have a lock on the file in question.

Hi,

"A generic error occurred in GDI+" indicates something went wrong in Win32 code.
I guess bmp.Save failed because of: file in use, path does not exist, disk full,
or something similar. Try the same path with either Windows Explorer manually,
or programmatically with File or FileInfo; that should tell you what the problem is.

Yeah, as opposed to the other folks here, who are all hoping it takes a week, I know.

This is still a stupid question. Perhaps if you took the advice you were given, and phrased your question better, we'd have some idea what you're talking about.

I assume you're selecting from a database. My advice would be, turn off your computer. Buy a book on SQL ( or perhaps learn how to use google, which means turning the PC back on ). Work through whatever tutorial you select.

And, in future, don't just ask the same question over and over, think about what the answers you get mean, and how you can help us to help you. If you mean something other than how do you add more than one column to a SQL statement, then please make clear what it is that you mean.

For the record, select * from myTable will return all columns, select col1, col2 from myTable will return the columns names col1 and col2.

TcpListener/TcpClient not working!

You need to write code to support drag and drop for the object you're dragging/dropping. There are tutorials on MSDN

Hello everyone!

I have 2 programs, a server and a client. If I start them both on the same computer, it works flawlessly. However, if I try a computer on the network (which I can do Windows file/printer sharing with) with one of the apps, the client says that the target machine actively refused it.

At first I thought it was my router, since I've been having some problems with it lately. But then I used my neighbor's wireless connection with 2 laptops and tried it, no result. So it's got to be my code.

Server:

server = new TcpListener(port); // port: 77
server.Start();

Client:

sock = new TcpClient(host, port); // host: 'localhost' or '192.168.0.100'; port: 77

As I said, both programs work fine on the same computer. Does anyone know why this might happen? Maybe my neighbor's router is crappy too?

Thanks in advance!

I do not know if this can help....
for your information.

1) you can check your window firewall setting.
If your firewall is on,you can set the exception for port 77.

2) To get all the listenning ports at server, you can try 'netstat /a' command at Server command prompt.

-- To test the connection from client, you can also try 'telnet [hostIP] [port]' command at Client command prompt.

Wish u luck. Smile | :)

I use the Windows firewall and PeerGuardian. For the Windows one, I clicked 'Unblock' the first time I ran it, and PG doesn't block it.

Netstat gives me this:

TCP presser:77 presser Blush | :O

LISTENING

Wait, shouldn't both the local and foreign addresses be the same? Why is one 77 and the other zero?

And bola_shokry, that link didn't work.

Any more ideas? Thanks you both!

Well, his problem is kind of different. His computers can see each other on a network, mine can't. Frown | :-(

But I got something here. I disabled both the Windows Firewall and PeerGuardian and guess what, Apache works. I tried my program but nope, that doesn't work yet. But wait a minute... 'telnet 192.168.0.100 77' gets through! Then how come my client doesn't?! I updated the code:

IPEndPoint ep = new IPEndPoint(IPAddress.Parse("192.168.0.100"), 77);
sock = new TcpClient(ep);

But it still isn't working... Ideas? Thanks for helping me!
