How to run a desktop application?

[jaejoong]

I got this error from another computer, without visual studio.

See the end of this message for details on invoking 


    just-in-time (JIT) debugging instead of this dialog box.

    ************** JIT Debugging **************
    To enable just-in-time (JIT) debugging, the .config file for this
    application or computer (machine.config) must have the
    jitDebugging value set in the system.windows.forms section.
    The application must also be compiled with debugging
    enabled.

    For example:

    <configuration>
        <system.windows.forms jitDebugging="true" />
    </configuration>

    When JIT debugging is enabled, any unhandled exception
    will be sent to the JIT debugger registered on the computer
    rather than be handled by this dialog box.

C#

//EMPLOYEE CONNECTION
                string connectionString = String.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 8.0;HDR=YES;IMEX=1;\"", txtOtherDimensions.Text);
                string query = String.Format("select * from [{0}$]", "Other Dimensions");
                try
                {
                    OleDbDataAdapter dataAdapter = new OleDbDataAdapter(query, connectionString);
                    DataSet dataSet = new DataSet();
                    dataAdapter.Fill(dataSet);
                    dataGridView1.DataSource = dataSet.Tables[0];
                }
                catch (Exception)
                {
                    MessageBox.Show("Invalid sheetname, it should be Other Dimensions");
                    return;
                }

I have already installed, .net framework 2,3.5 and 4. I also installed MS Office. What should be the problem? Am I missing something?? Please help me. Thank you!

I don't see anything in that code that would cause that exception.

How are you deploying the app?

[ddanbe]

Is the right version of .NET installed on the target machine?

DEploymant and versions have nothing to do with this... at least until you check the real cause... it's a coding error, but you have to find it.

What the error message is saying is that somewhere in the non-microsoft function PAMS_Upload.frmMain.Validate_OtherDimensions() an object property or function was accessed but the object was null. Until you find out what that line of code is, the rest of the trace is of no interest.

Once you do find out what that line of code is... then you may find that the object that failed was passed as a parameter... in which case the next lin of the trace is showing you which bit of code called Validate_OtherDimensions()... so you look there... in PAMS_Upload.frmMain.btnLoadOther_Click(Object sender, EventArgs e).

Sorry to disturb you all.

I notice the problem was the PC I used is not applicable to my stored procedure. It does have an invalid username that my active directory can't read.

Thank you all for answering.
