I have application that codes and binds an access database to a windows form application. Everything seems to work however, nothing is actually saved in the database. Updates and deletes are coded and debugging steps through, but checking the db, the data is the same.
View 2 Replies View RelatedI have an application which inserts large amount of data in Access database. So to speed up the things i have set Indexed property to No.
So at the end of insertion i need to set the index to the column of the one of the table to Indexed (Duplicates OK) through C#.
I have an extremely annoying problem, I am inserting data into an access database and now i have noticed that it is copying itself to the bin/debug folder on ts own and yet i have set "Copy to Output Directory" property to "Copy never"
But without fail, it is copied! It is making any attempted updates to the database's information invalid since its not updating at all.
This all started when i installed crystal reports and it asked me to make a duplicate of the database in order to utilize data-sets that were created for certain reports.
Why this is happening? I cannot test my application properly at all.
i'm trying to update multiple table values with same column using one query.
Here's what i've tried so far:
mySql.CommandText = "Update tbl_employees,tbl_emp_additional_info,tbl_allocated_deductions,tbl_benefits,
tbl_cashadvances,tbl_deduction_history,"+
"tbl_dtr,tbl_empabsences,tbl_empstatus,tbl_otherdeductions
,tbl_ots,tbl_payroll_history,tbl_rdcomments,tbl_reversed_deductions,tbl_reversed_deduction_paid "+
"set tbl_employees.emp_id=@newemp_id,tbl_emp_additional_info.emp_id=@newemp_id,tbl_allocated_deductions.

I've also tried removing all the other "and" operators but still no luck.It doesn't throw in exception yet it doesn't update my tables column values.
I'm new to c# and i'm using vs 2013 and access database..my i need to do multiple update records after I filtered the records in datagridview
In my database table I have these fields ID(PK/autonumber), EID,Date,Day,Daystatus..
In my form I have a button and it's fucntion is filter by date using bidingsource.fiter and this was the result
EID------Date-----------Day---Daystatus
10175--10/11/2014---sat--------regular
10176--10/11/2014---sat--------regular
10177--10/11/2014---sat--------regular
10178--10/11/2014---sat--------regular
what I want to happen is when I click another button called "Apply to all" I want to Update all the daystatus to "Legal Holiday" of the filtered records..I know how to update one by one using simple update..but I need to do the multiple update..
I tried to make a code but it was updating all the records not the filtered only here's my code:
try {
OleDbCommand command = new OleDbCommand();
connection.Open();
command.Connection = connection;
string query = "SELECT EID From EmployeeTable";
command.CommandText = query;
String a = "Legal Holiday";

View 1 Replies View RelatedI am designing a database query and need simplification to the algebra:
Code:
((x > u) && (x < y)) || ((z > u) && (z < y)) || ((u > z) && (y < x))
And these are always true:
Code:
z > x
u > y
It's a range overlap algorithm.
I have an issue with a database call. I've got a database call that counts the number of entries in the database:
private static Int32 dbCount() {
SqlCommand cmd = new SqlCommand("SELECT COUNT (*) FROM Employees", conn);
conn.Open();
Int32 count = (Int32)cmd.ExecuteScalar();
conn.Close();
return count;
}
Afterwards I'm using this as a check throughout my application:
if (dbCount > 0) {
// do something
}
When I execute this code I'm getting the following error: "Operator '>' cannot be applied to operands of type 'method group' and 'int'"
So I'm guessing it has something to do with the cast of the dbCount-object but I don't understand why as I already stated that the count-object to be an Int32.
Am trying to update the MSI database via a transforms (MST) file. using below code.
WindowsInstaller.Installer inst = (WindowsInstaller.Installer)new Installer();
Database instDb = inst.OpenDatabase(MSIFile.FullName, WindowsInstaller.MsiOpenDatabaseMode.msiOpenDatabaseModeReadOnly);
instDb.ApplyTransform(MSTpath, MsiTransformError.msiTransformErrorViewTransform);
WindowsInstaller.View view1 = instDb.OpenView("INSERT INTO `Registry`(`Registry`,`Root`,`Key`,`Name`,`Value`,`Component_`) VALUES('" + Registry1 + "', '" + Root + "', '" + Key + "', '" + Name1 + "', '" + Value1 + "', '" + Component + "')");
view1.Execute(null);
view1.Close();
instDb.Commit();
When i try for MSI database before including instDb.ApplyTransform(MSTpath, MsiTransformError.msiTransformErrorViewTransform);
it worked fine for MSI, the values got updated in the MSI database, But i face error in the above line of code.

The file name is "movie.dat" and currently i was able to save data into the file in this order:
[movie_code] [movie_dur] [movie_title] [movie_rating] [movie_dir] [movie_genre] [movie_status]
[12345] [120] [Movie] [PG13] [Director] [Comedy] [Active]
I want to search for the "movie_code" and change the [movie_status] from Active to Inactive.
So lets say for example i have a movie code 12345 saved in my movie file. I want to change the value from "Active" to "Inactive"for argument sake.
This is the code i was trying to do it with:
Code:
FILE *movie_fp;
movie_fp = fopen("movie.dat", "r+b");
int m_code;
MOVIE movie_data;
printf("*** Welcome to the movie updater! ***
