Hello,.. Im a New Guy to this forum and 1st of all;... Hi :twisted:

im a newbie to c# programming as well ,,, anyway.. i have a huge issue ..
here is what s going to happen..

if (txtPath.Text != "")
                {
                    FileInfo fn = new FileInfo(txtPath.Text);
                    string p = txtPath.Text;
                    int pos = p.LastIndexOf(".");
                    string ext = p.Substring(pos + 1);
                    string newname = mid + "." + ext;
                    string path = Application.StartupPath.ToString() + "\\images\\" + newname;
                    fn.CopyTo(path);

                    sql = "INSERT INTO mobile(MID,MMNO,MPRICE,MINFO,MMANU,MPIC,MDOA) VALUES('" + mid + "','" + mmno + "','" + mprice + "','" + minfo + "','" + manu + "','" + newname + "','" + doa + "')";
                    dbcon.Open();
                    com = new OleDbCommand(sql, dbcon);
                    com.ExecuteNonQuery(); // executing the query ( sending the wehical )
                    MessageBox.Show("Successfully Inserted", "Record Insertion", MessageBoxButtons.OK, MessageBoxIcon.Information);
                    dbcon.Close();
                    picImage.ImageLocation = txtPath.Text;
                    txtPath.Clear();
                    FormClear();
                    txtMid.Focus();
                }

using the above coding.. im uploading a image from my form to a folder in my application root.. the coding works fine... i must mention that im using ole-db as well in here to send data to the db /..

what happens is when i close this form after uploading the image and stuff.. the startup path is changed to the folder where i chose a image.. :P

ex - c:/users/myimages

and the software seeks the .Database in the directory where i chose a image to upload,,, ( in my example it would be c:/users/myimages ) when i reopen the same form the application path has changed :confused:

so my question is ,,,

is their a way to reset the application path ?

Tnx in advance ;)

Welcome to the forum!
You have a couple options here. You can use reflection to get the executing path of the assembly. Or since you are new at it. I would just save that startup path to a string class variable. they use that from then on out. best place to do that is in the constructor.

public class Form1 : Form
 {
     private string StartPath = "";

     public Form1()
     {
       StartPath = Application.StartupPath;
     }

     ...
  }

Then just use that variable instead.

it ddint work out :(

i tired it.. but still the error comes,, the path is being reset after i upload a image.. and the changed path is the folder where i chose the image to upload....

Any Ideas ? to rest the location ?

i don't think you followed me, if Application.StartupPath gives you the dir you need the first time you call it. Then you can save that path to a string. and then from then on out use that string instead of the Application.StartupPath.

The reason why it "changes" is because the working directory changes when you change it in a open or save file dialog box. But that doesn't matter because when the program first run you saved that data to a variable that WON'T change unless you manually change it.

its a class variable, available to the entire form.

If it didn't work, post the code that doesn't work. I will tell you why.

            }
        }

    }
}

AS i mentioned, this is the non modified coding ;)

my purpose is to reset the application path after the data has being submitted to the Database.. i must mention this too.. i ddnt get any sort of errors in the code after using the dbloc var in winodws 7 and vista. but still the error occurs in Windows Xp although i updated the .net and SQL versions in it :|

Thanks alot for the quick response :) ill be waiting for a reply ;)

Edited 6 Years Ago by g2gayan: n/a

OK. you need to create a Class variable that is of string type. I will edit this source and post it back. there is no need to "reset" the startuppath.

using System.IO;
using System.Data;

using System.Data.OleDb;
using System.Windows.Forms;

namespace Login_Form
{
    public partial class frmAddMobile : Form
    {
        public frmAddMobile()
        {
            InitializeComponent();
			
			//Set start up path here.
			StartPath = Application.StartupPath;
        }

        // Global Areas Stuff - U Knw :D :D bt dnt ask me haridhaa :D ------------------------------------------------------

        // Global vars - new
        OleDbConnection dbcon;
        OleDbCommand com;
        string sql;
		
		//create string here in class to hold startuppath.
		string StartPath = "":

        // Creating the Onload event
        private void frmAddMobile_Load(object sender, EventArgs e)
        {
			//use startpath string instead of Application.StartupPath;
            string dbloc = StartPath + "\\G2.mdb";
            dbcon = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+dbloc);
        }

        // Method Used to Clear The Text Fields

        }

        private void btnSend_Click(object sender, EventArgs e)
        {

            if (txtMid.Text == "")

                // i removed if statements to make the coding bit smaller

            else
            {
               
                string mid, mmno, mprice, minfo, manu;

                mid = txtMid.Text;

                mprice = txtPrice.Text;
                minfo = txtInfo.Text;
                manu = cmbManu.Text;
                doa = DateTime.Now;

                bool id = checkid(mid);

                if (id == false)
                {
			// removed if to make code look smaller ;)
                }

                if (txtPath.Text != "")

                    string p = txtPath.Text;
                    int pos = p.LastIndexOf(".");
                    string ext = p.Substring(pos + 1);
                    string newname = mid + "." + ext;
				    //use startpath string instead of Application.StartupPath;
                    string path = StartPath + "\\images\\" + newname;
                    fn.CopyTo(path);

                    sql = "INSERT INTO mobile(MID,MMNO,MPRICE,MINFO,MMANU,MPIC,MDOA) VALUES('" + mid + "','" + mmno + "','" + mprice + "','" + minfo + "','" + manu + "','" + newname + "','" + doa + "')";
                    dbcon.Open();
                    com = new OleDbCommand(sql, dbcon);
                    com.ExecuteNonQuery(); // executing the query ( sending the wehical )
                    MessageBox.Show("Successfully Inserted", "Record Insertion", MessageBoxButtons.OK, MessageBoxIcon.Information);
                    dbcon.Close();
                    picImage.ImageLocation = txtPath.Text;
                    txtPath.Clear();
                    FormClear();
                    txtMid.Focus();
                }

                else
                {
                    MessageBox.Show("Please Select A Image From The DB", "What the Heck Are u Doin Men ?");
                }

            }
        }

    }
}

Now it should work fine :)
(I didn't check any of your code, I just replaced the parts that apply to the startup path)

Thanks.. I Did the something after reading your previous post ( tutorial post ).. and now i copied the source you modified as well , , it still gives errors in winxp :( i think its a bug of win xp or in my notebook :) , but it works fine in windows 7 and vista :)

anyway thanks for helping me out :) Thanks in advance sir :) You Rock :cool:

It could possibly be the .net version you have installed on the XP machine. but you might try using the another method that uses reflection.

just replace this line

StartPath = Application.StartupPath;

with this one

StartPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);

if it doesn't work on xp after that. It might be the .net version or a problem with your laptop. its all good code.

Thanks alot sir... it was with the version of the .net :)
i had to install 3.5 to get it working ...

sir... when i create a setup for it, can i embed the setup of .net and sql with it so that the users will no longer experience this sort of errors .. Thanks in advance :)

you can't embed the .net setup. but you can freely share the .net redistributable. But don't worry. if you use visual studio to create a .msi installer package, it will automatically make sure you have the required .net version installed and if not, it will prompt to install it from Microsoft.
