I can't find simple solution for the case below.
How can I get time of some action in my code, and display it simpe through Console.WriteLine() in format [Date] [Time] [Action]?
For example I need time when "Ford" is created:
Car c= new Car();
c.createCar("Ford");
|
|
|
|
|
c.Created = DateTime.Now

Why don't you modify the 'createCar Method in the 'Car class. Example:
public class Car
{
public void createCar(string carname)
{
var dt = DateTime.Now;
Console.WriteLine("\nCar {0} created at: {1} {2}", carname, dt.ToShortDateString(), dt.ToShortTimeString());
}
}If you need to keep track of all the 'Cars created by manufacturer, consider using another class (static ?) that maintains a collection of 'Cars. Or, you could use a static Dictionary<string, List<DateTime>> in the 'Car class.
public class Car
{
public static Dictionary<string, List<DateTime>> ManufacturerToCars = new Dictionary<string, List<DateTime>>();
public void createCar(string carname)
{
var dt = DateTime.Now;
if(! ManufacturerToCars.ContainsKey(carname))
{
ManufacturerToCars.Add(carname, new List<DateTime>());
}
ManufacturerToCars[carname].Add(dt);
Console.WriteLine("\nCar {0} created at: {1} {2}", carname, dt.ToShortDateString(), dt.ToShortTimeString());
}
}

Hi,
I am using MySQL for employee WinForm application. Some tables have images and Ia m currently saving it as blob which is killing the size of the database.
I want now to move it to a varchar field contains the file name or ID and save the physical file on the server instead of blob.
I want to know what's the best practice in this? Do I need to include FTP server and client in my application?
Is it possible to send the file with the database SqlConnection but receive it there in the server as physical file?
Please assist..
Thanks,

No - the simplest solution is to create an "employee photo" folder on the server, and share it, giving read-only access. Your client apps then read the file name from the DB and access the share directly:
Access to remote folder[^]
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
|
|
|
|
|
but the folder will also have confidential documents such as contracts and warning letters for employee and giving read only access will allow users to view every file stored in it.

You don't give the users the permissions to view the folder by default. Instead, have a server based application or a Web API retrieve the documents and have that with the appropriate permission. Then you back this up with access control for the user against that service.

Create a folder for specific document types, employee photos, contracts, correspondence etc
Or do as POH suggested and create a service, this is the preferred method as it removes the client access directly to the server. However this would require you to reengineer you data access

Hi!
I am able to send text messages to android using Google GCM by C# code.
But I am unable to send Images along with the text message.
Can anyone help in the same with some code.
--------------------------------
My code for sending message:
RegId = Id;
SENDER_ID = "1234567";
ApplicationID = "Google ID";
var value = txtnotofication.Text;
WebRequest tRequest;
tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send"); tRequest.Method = "post";
tRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
tRequest.Headers.Add(string.Format("Authorization: key={0}", ApplicationID)); tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message= {\"message\" : \"demo msg\",\"imgUrl\": \"http://justcash.co.in/img/logo0011.png \"}&data.time=" + System.DateTime.Now.ToString() + "®istration_id=" + RegId + "";
Console.WriteLine(postData);
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
tRequest.ContentLength = byteArray.Length;
Stream dataStream = tRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse tResponse = tRequest.GetResponse(); dataStream = tResponse.GetResponseStream();
StreamReader tReader = new StreamReader(dataStream);
String sResponseFromServer = tReader.ReadToEnd();
tReader.Close(); dataStream.Close();
tResponse.Close();

How to run the project with modules compiled on different platforms x86 and x64
or whether it possible to make a reference from x86 module to x64 attached DLL?
Actually there is no problem with compilation and assembly, but cannot run because of the following error
"An attempt was made to load a program with an incorrect format"
I'm aware that there is no way to run modules with different platforms in one process, but may be I can somehow reflect the methods from the dynamically linked DLL?

Do you have the source to the 'modules'? If so, just building them against 'Any CPU' should do the trick.

I need exactly x64 or ...
may be there is the way to use large arrays up to 2GB on x86 platform ?
|
|
|
|

No, you cannot mix 32 and 64 bit code in the same application.
|
|
|
|
|
Windows is one big platform which runs a lot of different applications at once no matter x86 or x64
This depends on the processor type (32 or 64 bit)
When the application is different from the processor bit, the one simulates the environment and still runs the application (of course when it can - from 64 to 32 is possilble)
So logically must be the way.. methinks
|
|
|
|

No, Windows is an operating system and runs in 32 bit or 64 bit mode, depending on the hardware. You cannot run 64 bit code on a 32 bit hardware platform. And you cannot mix 32 and 64 in the same application. You should go to MSDN and study the Microsoft documentation on the subject.
|
|
|
|
|
If you cannot rebuild all of the assemblies to a consistent format, you may be able to force them all to use 32 bit by using CorFlags[^] to enforce 32 bit in the assembly header.

I need to use large arrays up to 2GB
byte[] b = new byte[2000000000];
It possible just on x64 platform
|
|
|
|

Since when?
The indexer is a 32bit int in both x64 and x86 systems, and that means they are subject to the .NET limit of 2GB as the maximum size of any single object.
But...if you are trying to use data that large, it's likely that your algorithm could use some serious looking at - there may be more efficient ways to handle this than just blindly loading huge data into memory. What are you using it for?
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
|
|
|
|
|
Well... I'm receiving the data as byte array, containing the zip file - approx 24MB
Then I have to unpack it into 1,5GB file and pass it to another module as new byte array
...Otherwise I'll have to rebuild the target module I have no source code because it's not mine
|
|
|
|
|
That's some SERIOUS compression ratio going on there! Must be a whole load of redundancy in the source data...
But... If you are passing this to another module, you don't have any choice as to using x86 or x64 - you have to match the "target module": you can't switch between x32 and x64 code in the same process.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

yep.. I've just realized that.. 
The program is the legacy from the previous team, when the users did not send large amount of data and there was enough memory to unpack their files directly in RAM using the MemoryStream.
Now the situation was changed and the amount of "megabytes" is not considering as "large" anymore
|
|

You've lost me! Indexer is 32 bit means an object size limit of 2GB? Not really, it means that if you ignore the unsigned values you can have up to 2^31 elements per dimension of the array, which is enough for a 2,000,000,000 byte byte array as specified.
Arrays can have over 4 billion elements across dimensions, and the 2GB limit can be lifted on 64 bit platforms with the newfangled gcAllowVeryLargeObjects wotsit.
https://msdn.microsoft.com/en-us/library/hh285054(v=vs.110).aspx
I'd venture that a push you could just about get away with this in 32 or 64 bits with other dubious settings. Or die trying...

Rob Philpott.

I tried that trick on .net 45, but it doesn't work or I did something wrong
Just change the platform has real effect
