How can use windows form in ASP

Aug 03, 2012 03:17 PM|LINK

I create a program in C#, I try to make it to run directly from web page; Is it possible??? I'm very thankfully if you have any suggestion to help me

My Code

protected void Browse_Click(object sender, EventArgs e)
    {
        {
            openFileDialog1 ofd = new openFileDialog1();
            if (ofd.showdialog()== true)
            openFileDialog1.FileName = "";
            openFileDialog1.Title = "Choose a file to decrypt";
            openFileDialog1.InitialDirectory = @"C:\";
           
            string strFileToEncrypt = "";
            string strOutputEncrypt = "";
            string strExtension = "";

           
            if (openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                strFileToEncrypt = openFileDialog1.FileName;
                txtFileToEncrypt.Text = strFileToEncrypt;
                int iPosition;
                
                iPosition = strFileToEncrypt.LastIndexOf(".");
                if (iPosition == -1)
                {
                    MessageBox.Show("Invalid file. Please select proper file.");
                }

                strExtension = strFileToEncrypt.Substring(iPosition, (strFileToEncrypt.Length - iPosition));
                  
                string strEncryptedExt = "z_z" + strExtension.Substring(1) + ".encrypt";
                strOutputEncrypt = strFileToEncrypt.Replace(strExtension, strEncryptedExt);

                txtDestinationEncrypt.Text = strOutputEncrypt;
                
                btnFileEncrypt.Enabled = true;
            }
        }
    }

Not that kind of app as it interacts with the desktop etc, but it runs on your server so who is going to see the dialogue boxes?

The best option is to take the code you would use to encrypt and decrypt and place it into it's own windows library project. This way the code compiles to a DLL that could be included in both applications. All that is required then is to write the UI that is required for each platform, and then when you hit submit handle the inputs and pass them to your encrypt/decrypt objects.

do not call winforms controls from asp.net page....what you can do is that make such code which needs to run in moire trust and put it in silverlight...if you want to run that particular code on client side...

if you need some specific code to run on server, then you can think of windows services etc....rather than calling windows forms application form asp.net page...

Thanks,

Thanks for reply, I want to explain that my project about encrypt file with password and then upload it in server, then when person need that file he will put the password and then the server will decrypt the file and start download... In fact I built the project in windows form but I need the program like a page instead of using program

Hi,

According to your description, you can try to do as follows:
1. Write the corresponding code in the .cs.
2. Compile it to a .dll file.
3. Call the .dll file in the web page.
For details about how to compile the .cs file into .dll file, please try command below:
```
csc.exe
     /t:lib
     /out:<Your DLL Name>.dll
```
For details about how to invoke the .dll file in the web page, please check the link below:
