Re: Run .Net 4.0 WPF App on WinXP SP3 - .NET (Core and Framework) Discussion Boards

..and where is the *.mdf located? Write a small console-app that only does a select, try that - does it require admin-rights? Writing to local (config?) files? Where are those located?

Errm, .NET 4 is supported[^] on XP SP3.

Whoops! My bad. I ended up looking at the 4.5 page.

I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

Yeah, I know. I was accidentally looking at the .NET 4.5 page.

Yeah, I think I covered that adequately already.

And what does happen if a "normal" user tries to start it? Error messages? What do the log files of your app tell you? Any entries in EventViewer?
Which type of .Net Framework 4: "full" or "client profile"?

I get the following. But nothing in this message points to anything in my app, that I can see:

If it's not broken, fix it until it is

That stack trace would indicate that the program has successfully managed to start up and the user is interacting it when it breaks - the fact it's hitting the ICommand implementation suggests this.

Maybe, the hit on the command could just be the initial binding. But you're right, it seems to get further along than I initially thought.

I don't think so. The stack trace is indicating this is in response to a button click command.

Does that happen on that one customer's computer only, or can you reproduce it on other XP machines (setting up a Virtual Machine for such testing purposes in e.g. VMWare Player is quite useful!)?
Did you check the "zone identifier" of the dlls on the NTFS file system? I.e. a "normal" user may not be able to load them because they were "downloaded from the internet" and thus deemed dangerous, while for an admin different rules apply.

I am writing in VB.NET, enhancing a working program. Part of the program involves getting data from various outside sources and saving it in tables in an Access database. I am adding a new outside source (for the first time for quite a while), and am tearing my hair out trying to get code that is working with previously created DataTables and their derivatives to work with a newly created set.

I used the dataset configuration facility to create a DataTable based on a Query from my new Access table. The Access query returns all the fields of recent records in the Table and is updateable in Access. The dataset query is

SELECT PriKey, ChannelNumber, ChannelName, ReadingDate, Power FROM  qryRecentSpyderData

PriKey is an AutoNumber primary key. Other than different field names, I have an apparently identical setup working without problems in another function. The failing code is:

VB

        Dim dst1 As New EnergyDataSet
        Dim tba1 As New EnergyDataSetTableAdapters.SpyderMinTableAdapter
        Dim tbl1 As New EnergyDataSet.SpyderMinDataDataTable
        Dim rowData() As EnergyDataSet.SpyderMinDataRow
        Dim rowNew As EnergyDataSet.SpyderMinDataRow
...
        For intCount = intStart To 0 Step -1
            rowNew = tbl1.NewSpyderMinDataRow
            rowNew.ChannelNumber = intChannel
            rowNew.ChannelName = minhArray(intCount).strChannel
            rowNew.ReadingDate = minhArray(intCount).dtSampleTime
            rowNew.Power = minhArray(intCount).sngPower
            tbl1.Rows.Add(rowNew)
        Next

The Rows.Add line throws a "Nulls not allowed" exception the first time through the loop. If I relax constraints, it throws a "Duplicate Primary Key" exception the second time through. I know that I haven't set the Primary Key - Access will set it in due course! I cannot see why this fails, while essentially identical code using what appears to be an exactly comparable dataset succeeds. What am I missing?

Well, I have a workaround - if I delete the reference to the Primary Key field in the DataTableAdapter definition, the code works and the database does get updated properly when I .Update it from the table. Since I don't need access to the Primary Key in the VB.Net code for anything, this is acceptable, but I still don't understand why the older code, whose table definitions include the relevant Primary Keys, works.

I am trying to create a custom ValidationAttribute in my c# .net code. I have done a lot of searching and have code that should be working but the IsValid method is not firing as far as I can tell.

Model code:

C#

[Required(AllowEmptyStrings = false, ErrorMessage = "required")]
            //[Range(2014, 2100, ErrorMessage="Please enter a valid year.")]
            //[RegularExpression(@"^\d{4}$", ErrorMessage = "Please enter a valid year.")]
            [ValidYear(ErrorMessage="Please enter one >= 2014")]
            [Display(Name = "Exp. Year")]
            public string expYear { get; set; }

And this is the class in that same model:

C#

public class ValidYearAttribute : ValidationAttribute
    {

        protected override ValidationResult IsValid(object value, ValidationContext validationContext)
        {
            return new ValidationResult("Something went wrong");
        }
}

Hopefully someone can help figure out why the IsValid is not firing.
Thanks
Mike

Hi,

I am developing an application in c#.net where I need to include the accounting information/transactions along with other data.
How this can be done? Please help.

Thanks in advance,
Guru.

There is not enough information in your question to be able to offer a reasonable response. If you have a specific programming problem then please provide clearer details. If you wish to learn accountancy then this is probably not the best place.

protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
con1.Open();
SqlCommand cmd4 = new SqlCommand("UPDATE candidate_personal_details SET GUARDIAN_NAME='" + TextBox23.Text + "',GUARDIAN_PH_NO='" + TextBox24.Text + "',GUARDIAN_MOB='" + TextBox25.Text + "',NATIONALITY='" + TextBox26.Text + "', GENDER='" + DropDownList1.Text + "',D_O_B='" + TextBox27.Text + "' , PRESENT_ADDRESS='" + TextBox28.Text + "',DIST1='" + TextBox29.Text + "' ,PIN1='" + TextBox30.Text + "',PERMANENT_ADDRESS='" + TextBox31.Text + "',DIST2='" + TextBox32.Text + "',PIN2='" + TextBox33.Text + "',LOCAL_GUARDIAN_NAME='" + TextBox34.Text + "',LOCAL_GUARDIAN_ADDRESS='" + TextBox35.Text + "' ,DIST3='" + TextBox36.Text + "',PIN3='" + TextBox37.Text + "' ,LOCAL_GUARDIAN_PH_NO='" + TextBox38.Text + "' ,LOCAL_GUARDIAN_MOB='" + TextBox39.Text + "'WHERE EMAIL_ID='" + TextBox21.Text + "'", con1);
SqlCommand cmd5 = new SqlCommand("UPDATE educational_details SET X_N_O_INSTITUTION='" + TextBox40.Text + "',X_N_O_BOARD='" + TextBox41.Text + "',X_Y_O_PASSING='" + TextBox42.Text + "',X_O_MARKS='" + TextBox43.Text + "',XII_N_O_INSTITUTION='" + TextBox45.Text + "',XII_N_O_BOARD='" + TextBox46.Text + "',XII_Y_O_PASSING='" + TextBox47.Text + "',XII_O_MARKS='" + TextBox48.Text + "',G_N_O_INSTITUTION='" + TextBox50.Text + "',G_N_O_BOARD='" + TextBox51.Text + "',G_Y_O_PASSING='" + TextBox52.Text + "',G_O_MARKS='" + TextBox53.Text + "'WHERE EMAIL_ID='" + TextBox21.Text + "'", con1);
// SqlCommand cmd3 = new SqlCommand(sql2, con);
cmd4.ExecuteNonQuery();
cmd5.ExecuteNonQuery();
con1.Close();
Label66.Text = "data is updated successfuly...";
// cmd3.ExecuteNonQuery();

}

Not surprising; add a space before the "WHERE" keyword. It'd be a bit more safe (google for Sql Injection) and a whole lot more readable if you use parameterized queries;

C#

using (var con = new System.Data.SqlClient.SqlConnection())
using (var cmd = con.CreateCommand())
{
    con.ConnectionString = "<insert your connectionstring here>";
    con.Open();

    cmd.CommandText = @"UPDATE candidate_personal_details
                           SET GUARDIAN_NAME=@GuardianName

    cmd.Parameters.AddWithValue("@GuardianName", TextBox23.Text);

    cmd.Parameters.AddWithValue("@GuardianNationality", TextBox26.Text);
    cmd.Parameters.AddWithValue("@GuardianGender", TextBox27.Text);
    //..and so on for all paramenters
    cmd.ExecuteNonQuery();
    cmd.Parameters.Clear();
    cmd.CommandText = @"UPDATE educational_details
                           SET X_N_O_INSTITUTION=@X_NO_Institution

    cmd.Parameters.AddWithValue("@GuardianGender", TextBox27.Text);
    //..and so on for all paramenters
    cmd.ExecuteNonQuery();
}

I'd strongly recommend to give the controls REAL names, like "GuardianNameTextBox" - it'd be a bit more friendly than having a "TextBox24" in there. It's also a non-normalized database. What happens when a "DIST4" is required?

hi

i have written 3 different select query in mysql based on yesterday,today, tommorow dates to get the birthday details as follows
select concat(name,', ',title) as 'Yesterday 30-04-2014' from personal_details where DOB=curdate() - interval 1 day
select concat(name,', ',title) as 'Today 01-05-2014' from personal_details where DOB=DATE(NOW())
select concat(name,', ',title) as 'Tommorow 02-05-2014' from personal_details where DOB=curdate() + interval 1 day

how to join all 3 query results to one, i need to show as below
Yesterday Today Tomorrow
aaaa gggg nnnnn
bbbb hhhhh mmmm
dddd jjjjj
eeee
ffff

How to achieve this, i am not able to do.

If i tried with join there it wont match any condition and will not work because in each query result i will get unique values.
I tried with another query by putting as below

select a.* from (select CASE DOB WHEN (curdate() - interval 1 day) THEN concat(name,', ',title) ELSE '' END AS 'Yesterday', CASE DOB WHEN (DATE(NOW())) THEN concat(name,', ',title) ELSE '' END AS 'Today',CASE DOB WHEN (curdate() + interval 1 day) THEN concat(name,', ',title) ELSE '' END AS 'Tomorrow' from personal_details ) as a where a.Yesterday IS NOT NULL and a.Today IS NOT NULL and a.Tomorrow IS NOT NULL

It is showing the result like in all the three column some rows will be null

I dont want null values in any column. i want output as above.

How to achieve this. If anybody knows please reply me.

Thanks in advance.
