how to give a database connection to a c++ code i am using turbo c++ as an editor and if i have oracle 11g client, odbc as a driver , what else i require and how to link these things in a code.
View 1 Replies View RelatedI 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.
I want to connect an access database (.mdb) to my Windows Forms application - this I can do and I have no problems viewing my table in server explorer.
Some code example or template that I can use as a base to learn from - I have literally trawled Google and Youtube and cannot find what I am after.
What I want to do is have a basic form, 2 text boxes and a button to save the data to my database.
FirstName and LastName are the 2 boxes.
How do I count the objects(for example botton) on the form

SQLite error
near "16": syntax error
On the code:
private void btnUpdate_Click(object sender, EventArgs e)
{
for (int i = 0; i < dataGridView1.Rows.Count; i++)

With breapoints etc it does show the values it has to insert into my database. But it just doesn't and gives me the Near "16" syntax error.
I have a problem with my C#. Trying to create the airstrip with planes heading out of the hangars and on to the road to the airstrip. Each Hangar pannel is connected with closes road to them. What i am stuck with right now is connecting the roads together so each one of them will see if the next road is free and if it is it will send the plane (colorder square for now) to it and then proceed to the next one when finaly they will line up for the final panel(airstrip) and take off.So far they are just going down the each road they are assigned with semaphore and thread.

Connecting the "p2" with "p5" so the graphics from "p1" the square will travel through P2 and P5 this would be great and will allow me to procede with my studies.
Also i do realise that this might not be the best ways of using concurrent Csharp and not the up to date one but this is what i have been assigned with and do not have any other options unfortunately.
How i understand this is that i need to have 3 buffers and 3 semaphores for each panel. But i do not know how to add those to each one of them and then connect it with the next one as if i try and add them it either puts a cross in the design view over that panel or says that there is limited options for this statement.
This is the way that i want to do it unfortunately it must be so. The most flexible this can be is by adding an array for semaphores and buffer ( do not know how to do that either).
I have tried to connect my sql server 2005 using a domain name. i have bought a domain name and a dns client. this is my connection string
{ SqlConnection sqlconn =
new SqlConnection("user id=user1;" + "password=pass2;"
+ "server=www.mysite.infoServerInstance;"
+ "trusted_Connection=false;" + "network
library=DBMSSOCN;" + "Integrated security=false;"
+ "initial catalog=Mydatabase;" +"connection timeout=5
;"); }
I have added sql browser & sql server in fire wall, and also enabled tcp port 1433 and udp port 1434. the above connection string works perfect when i run it in the server machine, but whenIi try to run it on other machines I am getting an error that server is not available or cannot find the specified server.. I desperately need to access my database through an url. ie., through internet..
The main question how to fully traverse/circumvent through all TreeView, for transforming Tree structure into a Table structure.
I want to note that the TreeView may contain a different number of branches, with different depths and different names.
I found a lot of information how to populate TreeView e.g. from DataTable, but I didn't found information how to recursively traverse/circumvent a TreeView and populate/fill data e.g. to DataTable.
As sample I have following TreeView:
Aaron
-Baldwin
--Caleb
---Dale
--Earl
-Fabian
Gabriel
-Harold
-Ian
Necessary to convert the TreeView into e.g. DataTable:
id | Name | ParentId
--------------------------------
1 | Aaron | null
2 | Baldwin | 1
3 | Caleb | 2
4 | Dale | 3
5 | Earl | 2
6 | Fabian | 1
7 | Gabriel | null
8 | Harold | 7
9 | Ian | 7

I'll work soon on a program that should take the finger print from a reader and save it in sql server to determine employees's presence and leaving. My questions are:
1- Is the written code differ from one reader to another? or any code apply to all readers?
2- I knew that i should take the image and save it in varbinary in sql server, but how i shall take it?
3- Libraries i should use in visual studio 2010 and c#?
4- should i write license with a definite number of fingerprints save?
5- when i try to approve an employee pressece (by taking his fingerprint), shall i go directly to his id in SQL server and compare his fingerprint stored with the new one entered, OR i Should take the fingerPrint and search for it?

Data is displaying in grid view but when i enter the particulars it's not inserting in to DB & grid view.
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.
