So when I create the EF and use generate model from the database, I included the sensitive info into the connection string. Now I want to get the user to input password, userID, schema name, host into the connection string. I use Oracle as my database, so there is a need to put the schema name in it also.... How do I accomplish this task? Been trying to get it work but unsuccessful so far...
View 3 RepliesI am trying to parse a text file that contains information and i cant seem to get started. For example, the text file looks like this:
idx=929392, pl= 12, name= someperson
age=19
state=ma
status=n/a
idx=929393, pl= 12, name= someperson2
age=20
state=ma
status=n/a
idx=929394, pl= 12, name= someperson3
age=21
state=ma
status=n/a
I want to parse the name and age into another text file like this format:
someperson 19
someperson 20
someperson 21
possibly include other attributes next to the age like idx?
I have my application database in the AppDataRoaming folder. I'm trying to create a connection string for Telerik reporting, up until now I've had a connection string in a settings class that is put together like this:
The path is:
data source=C:UsersSynlightAppDataRoamingAppNamedataAppDB.sqlite
I've tried files paths like this:
%AppData%RoamingAppDatadataAppDB.sqlite
and
Server.MapPath(@"~App_DataRoamingAppDatadataAppDB.sqlite
(those are not the real directory names, of course). How do I create a connection string that will work on target machines?
private DataSet1 GetData(string query) {
string conString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
The above is erring out with NullReferenceException
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

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..

View 2 Replies View RelatedI downloaded Oracle instantclient-basic-nt-12.1.0.1.0.zip and instantclient-sdk-nt-12.1.0.1.0.zip and extracted both to c:oracle I then went into visual studio 2013 and created a Win32 Console application with all default parms.
I then went into project -> properties -> C/C++ -> General -> Additional Include Directories and added my include path C:oraclesdkinclude

i have tried to search on the Internet but haven't found a suitable result that links in with what I want to do, that is to creation a WPF application and when you press a enable button it will enable the LAN and when I click the disable button it will disable the LAN until i click the enable button again. Now I know how to creation a WPF and the buttons, but how would I do the disabling LAN and enabling LAN?
By LAN i mean just the networking adapters, so that the PC cannot connect to a router and then the Internet.

I am designing a server program in C++ and now that everything works for the clients, I would like to implement a command line. The code waits for a connection with the predefined function "new_socket = accept(serversocket,(struct sockaddr *)&client,&addrsize);". I already made a function for the command line but I can't find a way (in my brain or on the web) to accept commands (getline) whilst no connection is accepted yet. (I mean wait for a connection. If no connection, then be ready to receive some arguments from the command line). Here is part of the code:
cout << "Waiting for connection/command...";
command_line_function(); //getline(cin,string)
while(true){
new_socket = accept(serversocket,(struct sockaddr *)&client,&addrsize);
if(new_socket == INVALID_SOCKET){ //INVALID_SOCKET is an error somehow.
error_function();}
cout << "ACCEPTED
";
//etc.
}

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.
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.

using System.Windows.Forms;
using System.Threading;

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).
