Yours a homework question, so my answer not going to be acceptable, but for your amusement, read on.
Sajo Nezic wrote: I need help with generating random decimal numbers from 5 to 6 (For example 5.1, 5.2 etc.) That's a question from a user. As a developer, you supposed to see that "5" is a constant and not relevant to the question. You generate a float and put a "5." string in front of it. Gives you instantly one more digit to play.
So the next thing the user wants is "random data". There's this thing called a "youtube" giving you very large blobs of random data. Not "random" enough for homework, but random enough for encryption using one-time-pads. The amount of data available is overwhelming.
Back to your position; you get multiple errors, and we cannot guess what wrong on "multiple", as the answer is "multiple". Show us your code, let us argue for a day and then come back. Your code cannot be more wrong than my first code, so just share and learn.

There is a lengthy discussion (with code examples) of generating random decimal numbers in C# here: [^].
imho, very few apps need greater random number "integrity" than that provided by the Framework (see OriginalGriff's solution, here), or, by using the other native crypto facilities: [^]

Hello
I have a problem statement for which looking for a solution.
Requirement:
1. I have around 1000 files and all are in different folders e.g
2020-08-11->
Folder 1 -> file 1
folder 2 -> file 2
2. Wanted to write a program which will extract lines from these files and create one output file
3. Input Lines to read came from Database table e.g
one column in table which stores the input for the program.
Any suggestion or reference is appreciated. Not a good at C# programming

And?
What have you tried?
Where are you stuck?
What help do you need?
All we have so far is a "wish list"!

Hi everyone!
Does anyone have a sniblet to be able to detect if the device is enabled or disabled in device manager. I've done a bit a searching and couldn't find anything of use when attempting to get a status of a device.
What I have so far, it appears the value I am obtaining by marshaling my Data stays the same regardless of its status so my API call is incorrect or the way I am marshaling out and I was hoping one of you may have a sniblet that actually works.
Below are two failed attempts at getting the device status :\
Thank you!!

Hi, I'm not familiar with most of the functions you're using, but maybe this helps:
I once was interested in the enable/disable status of my Ethernet connection, as set in the Control Panel Network Connections (which might be different from the choice offered in Device Manager).
I used WMI (class Win32_NetworkAdapter), and checked property NetConnectionStatus which was zero for disabled and non-zero (7 IIRC) for enabled.

Here is fresh code that works for me:
using System;
using System.Management;
namespace LP_Core {
public class LP_Ethernet {
public static string GetState() {
string query = "SELECT NetConnectionStatus FROM Win32_NetworkAdapter "+
"WHERE NetConnectionID='Ethernet'";
ManagementObjectSearcher ethernets = new ManagementObjectSearcher(query);
foreach (ManagementObject ethernet in ethernets.Get()) {
switch (Convert.ToInt32(ethernet["NetConnectionStatus"])) {
case 0:
return "disabled";
case 7:
return "enabled but disconnected";
case 2:
return "enabled and connected";
default:
return "unknown";
}
}
return "absent";
}
}
}

Luc is being modest. If he says he got a better idea, you better follow it.
Not every device is complete in terms of device-drivers. I have a mountain of webcams that don't work under Linux to prove so.

Bonjour,
Je voulais déployer mon web service en IIS.
Ce web service crée en C# permettant de connecter à une base oracle 11g.
J'ai utilisé comme connecteur Oracle Data Access.
Le web service fonctionne localement mais après déploiement j'ai le message suivant :
Oracle.DataAccess.Client.OracleConnection --> Oracle.DataAccess.Client.OracleException: The provider is not compatible with the version of Oracle client à Oracle.DataAccess.Client.OracleInit.Initialize()
Le connecteur Oracle Data Access est en 32 bits alors j'ai activé les applications 32bits en IIS mais le même problème.
Merci.
Google translate: Hello,

The web service works locally but after deployment I have the following message:

The Oracle Data Access connector is 32-bit so I enabled 32-bit applications in IIS but the same problem.
Thank you.

Read the error message:
The provider is not compatible with the version of Oracle client
It means that the engine and client versions are not compatible: you are trying to access a newer DB with an older client (or possibly vice versa but it's unlikely).
Think about it: if your code is written for V1.0 of a file format, and you try to work with a V5.6 file you would corrupt the file or discard data.
That's what the error is saying: "it's too new for me, I don't understand the differences, so I'm not going to risk your data"
Google translate: Lisez le message d'erreur:
Le fournisseur n'est pas compatible avec la version du client Oracle
Cela signifie que les versions du moteur et du client ne sont pas compatibles: vous essayez d'accéder à une base de données plus récente avec un client plus ancien (ou peut-être l'inverse mais c'est peu probable).
Pensez-y: si votre code est écrit pour la V1.0 d'un format de fichier et que vous essayez de travailler avec un fichier V5.6, vous corrompriez le fichier ou supprimeriez des données.
C'est ce que dit l'erreur: "c'est trop nouveau pour moi, je ne comprends pas les différences, donc je ne vais pas risquer vos données"

Bonjour,
Merci pour votre message.
Voici la version de base :
Oracle Database 11g Entreprise Edition Relase 11.2.0.4.0 - 46bit Production
Voici la version de driver ODAC112040Xcopy_32bit
avec l'ensemble de .dll :
oci.dll
ociw32.dll
Oracle.DataAccess.dll
oramts.dll
oramts11.dll
oramtsus.dll
orannzsbb11.dll
oraocci11.dll
oraociei11.dll
oraOps11w.dll
orasql11.dll
Le projet web service fonctionne tout seul et aussi lorsque j'ai inclu dans un autre projet.
Maintenant, je voulais déployer le web service pour que ceux qui veulent les utiliser alors ils peuvent le référencer à travers l'URL de ce web service.
Mais le même message d'erreur !!!

Hello,
Thank you for your message.
Here is the basic version:
Oracle Database 11g Enterprise Edition Relase 11.2.0.4.0 - 64it Production
Here is the driver version ODAC112040Xcopy_32bit
with the set of .dll:
oci.dll
ociw32.dll
Oracle.DataAccess.dll
oramts.dll
oramts11.dll
oramtsus.dll
orannzsbb11.dll
oraocci11.dll
oraociei11.dll
oraOps11w.dll
orasql11.dll
The web service project works by itself and also when I have included it in another project.
Now, I wanted to deploy the web service so that those who want to use it so they can reference it through the URL of this web service.
But the same error message !!!

It looks like you are trying to mix 32-bit and 64-bit, which will not work.

Good day.I have a VS2017 C# solution (A) with 3 projects under this solution and the whole solution is in Git repository.
Now, I just created a small Windows form solution C# (B) with single project. How can I add this new solution(B) to the existing solution(A) so that at the end I can push the exisitng git repository(A) along with the new solution as part of it. I tried this way: Added solution folder of B to the solution folder of A. Now what? I can open up Team explorer in A or B. How can I achieve this in VS or in Git? Please advice an easy way.Thanks

Solutions do not contain other solutions.
A solution is a collection of Projects. So, you can open the Solution you're trying to add to and just add an existing project to it. Navigate to the .proj file in the project folder you want to add to the solution.
