It's fun to chain .Replace but it keeps you from knowing what's happening from one to the next.
It's not any faster than using the occasional intermediate variable.
If you chain that many, at least put them on a separate line.
string strformula = Regex.Replace(maindata, "\"" + data
.Replace("(", "\\(")
.Replace(")", "\\)")
.Replace("$", "\\$") + "\"", "W51",RegexOptions.IgnoreCase);
Then it should also be obvious that "data" should have it's own statement.

Hi, folks.
I'm programing in C# in Visual Studio 11. I changed a form font to bold (unique change) but as I didn't like the efect, I tried to return the form to regular text, but VS didn't return the form to regular font, no matter what. I noticed it's impossible to go back. Does anyone know how to do this? What am I doing wrong?
Thanks.

How did you change it, and how did you try to reset it?

Hi, Richard.
I changed the font in the Properties Tab.
Do you have any idea?
Thanks.

You are going to have to be a lot more explicit about exactly what you did - when I tried it by adding a new form, dropping a Label and TextBox on it, setting the TextBox text to "ASDFGHJKL", and then switchign the Form.Font.Bold property to "True" in the designer, it bolded all the text (other than the form caption).
Switching it back to "False" in the designer reversed that without problems.
So what did I do that you didn't?
And what version of VS are you actually using? They normal go by years: I run Visual Studio 2019 for example.

Hi, OriginalGriff.
I did the same as you. My VS is 2019, version 4.8.04084.The problem continues. I changed the font to Bold, and it worked fine, but the form changed the size (became a little bigger). Then I removed the Bold and the form removed the bold, but continued bigger. When I look at the form properties, the font appears as bold, although Bold is false.
I think the best to do is to recreate the form. If there is a way to include an image here, please tell me how, and I can show you what I'm saying.
Thank you.

Any Help, please
I am new in Web Service.
I have this WS
[ServiceContract]
public interface IWSEPSService
{
[OperationContract]
Persona ObtenerPersona(string id, string TipoDocumento);
[OperationContract]
Cliente SaveData(string documento, string tipoDocumneto);
}
[DataContract]
public class Persona : BaseRespuesta
{
[DataMember]
public string Nombre { get; set; }
[DataMember]
}
[DataContract]
public class Cliente : BaseRespuesta
{
[DataMember]
public int id { get; set; }
[DataMember]
public string direccion { get; set; }
more properties..
}
/* Class Persona */
public Persona ObtenerPersona(string Id, string tipoDocumento)
{
if (tipoDocumento == "Cedula")
{
if (ValidaCedula(Id) == false)
{
return new Persona() { Error = "Cedula erronea" };
}
}
/* Class CLiente */
public Cliente SaveData(string documento, string tipoDocumento)
{
if (tipoDocumento == "Cedula")
{
if (ValidaCedula(documento) == false)
{
return new Cliente() { Error = "Error Cedula incorreta." };
}
else
{
dt = ConsultaDatosClientes(documento, tipoDocumento);
foreach(DataRow row in dt.Rows)
{
if (tipoDocumento == "Cedula")
{
nombre = row["nombre"].ToString();
apellido = row["apellido"].ToString();
}
In the client Side I have this:
1. This code works perfect
private void button1_Click(object sender, EventArgs e)
{
var cedula = txtCedula.Text;
using(WSEPSService.WSEPSServiceClient client =new WSEPSService.WSEPSServiceClient())
{
var Persona = client.ObtenerPersona(cedula,"Cedula");
txtNombre.Text = Persona.Nombre + ' ' + Persona.Nombre;
txtEdad.Text = Persona.Edad.ToString();
}
}
2. This code does not work
private void btnSalvar_Click(object sender, EventArgs e)
{
using (WSEPSService.WSEPSServiceClient client = new WSEPSService.WSEPSServiceClient())
{
var Salvar= client.SaveData("10233317", "RNC"); // Here the program stopped
}
}
This is the Error:
System.ServiceModel.FaultException: 'The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework SDK documentation and inspect the server trace logs.'

Read the error message - it tells you exactly what to do to find out what the problem is:
'The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework SDK documentation and inspect the server trace logs.'
So do what it says: turn it on and see what actual information it gives you!

Did you want to ask a question about code you're writing or did you just want to beg for code?
Begging for code isn't going to get you any where. This isn't a "code to order" site.

If I am researching a new technique or technology, something I like to do is look on Google to see what others have written about the topic. It's very rare that I can't find information supporting it. Sometimes, finding the answers you want is all about the keywords you use, so searching for k-medoids in C# really hit the spot. k-medoid clustering code c - Google Search[^]

I'm having trouble creating the 32-bit version of a registry key. In RegEdit I can see the 64-bit version of the key, but not the 32-bit version.
This is my code:
RegistryKey Key = RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64);
RegistryKey WowKey = RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry32);
RegistryKey SubKey = Key.CreateSubKey(@"Software\Company Name\App Name");
RegistryKey WowSubKey = WowKey.CreateSubKey(@"Software\Company Name\App Name"); Where is the 32-bit version of the key supposed to show up in RegEdit?
I thought it's supposed to show up here:
HKEY_CURRENT_USER\SOFTWARE\Wow6432Node
The difficult we do right away...
...the impossible takes slightly longer.

You're creating a key with the 32-bit view, but that doesn't mean the keys you create end up under Wow6432Node. It's being created exactly where you told it to be created:
HKEY_CURRENT_USER\SOFTWARE\Company Name\App Name
The first line creates the key, then the second line tries to create the same key but it's already there, so it just returns a handle to the existing key. You now have two views, 64 and 32-bit, of the exact same key.
Change the names of the keys you're creating in the 32-bit version of the code and watch what happens.
EDIT:
It doesn't seem changing the view does anything. Both views read/write to the exact same key.

|

Thank you for your response.
It would appear that that's exactly what's happening.
I'm creating the keys in a 64-bit application, but the keys will be read by both 64 and 32-bit applications.
Are you saying that if the key I create off the 32-bit view base key has a different name, then it will do what I expect?
The difficult we do right away...
...the impossible takes slightly longer.
|

No, it'll just create the separate keys so you can see them both.
If you're going to write to anything under Wow6432Node, I think you have to build that into the path.
The real question is if you create the key under the normal path, "SOFTWARE\CompanyName\AppKey", is it still going to be readble by a 32-bit app on 64-bit Windows. I think that answer is yes.

I certainly thank you for the education. But I'm a little dismayed that it doesn't work the way I expected it to. It should open the 32-bit view if I specify so.

...the impossible takes slightly longer.

It's going to take a bit of homework, but I think Registry Reflection was removed from Windows, or at least disabled by default, in Windows 7. There's still may be a way to turn it back on and experiment with some true 64-bit and 32-bit apps. Leaving the build on AnyCPU would tend to add a variable to the experiments.

Reading data from xml file and load into datatable. i can not load data into List<t> because datatable has some dynamic column whose name is not known at compile time.
I have one List<t> and one datatable. _AllCommentsData is List<t> and dtData has datatable.
More or less _AllCommentsData has 10,000 to 20,000 data and dtData datatable has high volume of data. approx some dtData datatable has 70,00,000 data means 7 million data. when traversing in high volume of data and update one column value is taking long time. so guide me how to refactor or restructure the code as a result update one column value with high volume of data would take very less time. any work around exist to deal this situation?
i could join my datatable and List together and update field value but i could not do it because few column name is dynamic in datatable. so in LINQ select i can not mention their name and that is the reason i query datatable in loop and update data.
can i use Parallel.For() or AsParallel ? please guide me with some sample code which i can use to speed the data updation when there is high volume of data in data table. Thanks
My Sample Code which is taking long time for high volume of data.
foreach (var item in _AllCommentsData.Where(a => a.CommentType == "Only LI"))
{
if(item.Comments!="")
{
tmpData = dtData.AsEnumerable().Where(a => a.Field<string>("Section") == item.section
&& a.Field<string>("LineItem") == item.LineItem
&& (a.Field<int?>("EarningID") == null ? 0 : a.Field<int>("EarningID")) == item.EarningID);
if (tmpData != null && tmpData.Count() > 0)
{
tmpData.ForEach(x =>
{
x["LI_Comment"] = 1;
});
}
}
}

Have a look at my answer to your previous question: C# How to speed up for loop with large data iteration[^]
It's the same question - so it has the same solution, and the same caveats.
