Hi,

this is what I would try (not tested), and it doesn't use a PictureBox:

Bitmap bmIn=(Bitmap)Image.FromFile(sourceFile);
Bitmap bmOut=new Bitmap(4*bmIn.Width, bmIn.Height);
Graphics grOut=Graphics.FromImage(bmOut);
for(int i=0; i<4; i++) grOut.DrawImage(bmIn, bmIn.Width*i, 0);
bmOut.Save(destinationFile, ImageFormat.Jpeg);
grOut.Dispose();
bmIn.Dispose();
bmOut.Dispose();

hey... dont repost...

I think you cannot uninstall during system shutdown. Windows wait for ... seconds to shutdown all application, if the application cannot be end, then it will be killed.

You could set registry entries to remove the application on a windows startup.

you would run your app.
set the registry entries (runonce)
on restart the runonce would take effect and remove your app during windows startup.

Parameter names in your procedure and OracleParameter instance should match. Also you need to preserve the order in which parameters are added.

thank you for reply my post.i have done that in your way.but still it gives following exception. Frown | :(

"Invalid parameter binding
Parameter name: rec_"

here is my modified code.

OracleParameter rec_ = new OracleParameter();
rec_.ParameterName = "rec_";
rec_.OracleDbType = OracleDbType.Raw;
rec_.Direction = ParameterDirection.InputOutput;
rec_.Value = this.dataGridView1.Rows[0];
cmd.Parameters.Add(rec_);

As I said, parameters should be in the order which they have written in the procedure. So first id_ then version_ etc should come. rec_ should be the 3rd parameter.

How to create a dynamic web service from windows application

5-Oct-09 0:52

I am creating a windows application which take database configurations from user and save in an xml. I need some code help which will do the following task:
When the user press finish button:
1. It should create a web service which will be able to read data according to the database configuration.
2. Start the web service automatically
3. Configure the IIS server.
4. save the server address into a xml file which will be used by other to consume this service.

All the above points should be done in a single finish button click.
How can I do that. I need some guideline and sample code for that.

No Method will create a webservice for You .The webservice should be created by Yourself depending upon your requirement and it should be called in finish button.

I need some Idea for the following purposes please help me:

Suppose a user is installing my windows application. When the user completed installing, It should send a network address to me and start listening for sql from me. When I will send sql to the user's address it will execute it and return me the dataset or data table(I know how to execute sql and get dataset). As a result the final solution is that: The user will installe my application very easily and started to serve me by executing sql from his database. The user don't have to create a webservice on it's own. Everything should be done by my windows application. So what will I do. Is it possible to create web service and start listening by my windows application?(IIS server may be configured by executing a batch file). Or Should I use client/server socket programming for that? Please need suggestion and help somhow
