I have no trouble using MultilineStringEditor in my windows forms app. When I tried to create a custom text box class with that  in a library dll with same reference added, I get

Error	CS0246	The type or namespace name 'MultilineStringEditor' could not be found (are you missing a using directive or an assembly reference?)	mywindowsCtlLib	...

I am trying to port my project from .Net framework to .Net standards.  

This is basically consuming a WCF service which is running on the same system. So I am using Namedpipe , NetTCP and basichttp bindings in WCF.  I could not find any solution on how to consume WCF service over namedpipe binding from .Net standards. 

Any help would be greatly appreciated.

Thanks,

I am getting the below compile time error. Visual studio (2019) version is 16.3.3. and .net framework is 4.8.03752.How to fix it? Any suggestion please.

Task could not find "al.exe" using the SdkToolsPath "" or
the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\NETFXSDK\4.7.2\WinSDK-NetFx40Tools-x86".
Make sure the SdkToolsPath is set and the tool exists in the correct processor specific location under
the SdkToolsPath and that the Microsoft Windows SDK is installed.

ClrStack:

The left picture is that the file cannot be found, the right picture is no-error。

Why was the DLL on the left file deleted first, in a different order? why?

Hi,

I am using this if condition to search the data:

if (services.first_name.ToLower().Contains(searchBar.Text.ToLower()) || services.middle_name.ToLower().Contains(searchBar.Text.ToLower()) || services.last_name.ToLower().Contains(searchBar.Text.ToLower()) || services.email_address.ToString().Contains(searchBar.Text.ToLower()))

My data is like this:

public class UsersData
{
    public int user_id { get; set; }
    public string first_name { get; set; }
    public string middle_name { get; set; }
    public string last_name { get; set; }
    public string email_address { get; set; }

    public string full_name
    {
        get
        {
            string user_full_name;

            user_full_name = first_name;
            user_full_name += " " + middle_name;
            user_full_name += " " + last_name;

            return user_full_name;
        }
    }

    public string user_image
    {
        get
        {
            return string.Format("https://www.ajworld.app/gallery/photos/{0}.png", user_id);
        }
    }
}

but some values might be null in MySQL which cause a crash in my code, e.g. middle_name

How can i solve this please?

Thanks,

What we did for the last 6 months - Made the world's coolest reporting & docgen system even more amazing

Hi there,

Do you think when the azure app service platform is upgraded to Framework 4.8 in the next few weeks, the applications created using .NET Core 2.1 will be affected ? Even though the application I am talking about is built using .NET Core 2.1, the configuration of app service is only pointing to 4.7 till now, because there is no option for me to select .NET Core.

This implies to me that the Azure app service platform is still using .NET Framework to run its services. In such case, I may not be able to test my .NET core application on Azure app service pointing to .NET Framework 4.8 until the new framework is published in Azure.

Please clarify.

Thanks

Hello everyone,
I am trying to extract (copy/paste) MyFile.exe from the Resource of my project.
I have added "MyFile.exe" to my Resource of my project (myProject/Properties/Resources/Add Resource/ Add Existing File..)
I want to click this button to extract (copy/paste) "MyFile.exe" file from Resources to the E partition. 
Please help. Thanks.

I've used the following code, but it doesn't work (Microsoft .NET Framework 4.0 Client Profile):

public void ExtractFileFromResources(String filename, String location)
        {
            //  Assembly assembly = Assembly.GetExecutingAssembly();
            System.Reflection.Assembly a = System.Reflection.Assembly.GetExecutingAssembly();
            Stream resFilestream = a.GetManifestResourceStream(filename);
            if (resFilestream != null)
            {
                BinaryReader br = new BinaryReader(resFilestream);
                FileStream fs = new FileStream(location, FileMode.Create);
                BinaryWriter bw = new BinaryWriter(fs);
                byte[] ba = new byte[resFilestream.Length];
                resFilestream.Read(ba, 0, ba.Length);
                bw.Write(ba);
                br.Close();
                bw.Close();
                resFilestream.Close();
            }
        }

private void Extract()
        {
            ExtractFileFromResources("MyFile.exe", @"E:\MyFile.exe");          
        }

Hey

Looking for a little bit of help with some logic if thats ok? Cant seem to get it right..

I have some material names that i am passing through a method that searches for it in a library. If found, it returns the material associated with the name

Friend Function AssignMatsApps(ByRef PartDoc As PartDocument,
                                   ByRef StrMaterialName As String) As String

'if material name only contains A, change it for SA-
If Not StrMaterialName.Contains("SA") Then
            StrMaterialName = StrMaterialName.Replace("A", "SA-")
End If

Dim localAsset As Inventor.Asset = Nothing
Dim assetLib As Inventor.AssetLibrary = AddinGlobal.InventorApp.AssetLibraries.Item("STD_LIB")
Dim ReturnMaterial As String = String.Empty

'loop materials and find a match
For Each TryAsset As Inventor.Asset In assetLib.MaterialAssets
   Dim GetResult As String = TryAsset.DisplayName
    If GetResult.Contains(StrMaterialName) Then
       If GetResult = StrMaterialName Then
          ReturnMaterial = StrMaterialName
       Else
          ReturnMaterial = TryAsset.DisplayName
       End If
    End If

Dim libAsset As Inventor.Asset = assetLib.MaterialAssets.Item(ReturnMaterial)
localAsset = libAsset.CopyTo(PartDoc)

 Try
   PartDoc.ActiveMaterial = localAsset
Catch ex As Exception
End Try

Return ReturnMaterial

End Function

The intent is to compare the material name coming in with whats currently in the library and when a match is found, return the material so it can be assigned. This works except when there is a slight variation on the material name.

The material name in the library is always the same, here is a short list-

SA-105

SA-105N

SA-516 70

SA-516 70 B

SA-516C

notice the irregular pattern for the suffix letter? some are spaced, some are adjacent. One certain thing is there will only be one material name, nothing duplicated in a different format. for example; there will be SA-105N but not SA-105 N.

The materials that i pass into the function are

A105

A105 N

A105N

A516 70

A516 70 B

A516 70B

As mentioned above, these will all be converted to SA- numbers and i will use that format below.

What i need to do is find a match even if the material name being passed in varies. So for example, if i pass in these names

SA-105N or SA-105 N, i will return SA-105N (The library version). If i pass in SA-516 70 B or SA-516 70B, i will return SA-516 70 B. 

I tried using the replace  function to omit the space but that omits all spaces. Is there a function i can use that 'sounds like' the name so that it can cover a variation of the string to find a match?

I cant create a static list, the library is updated mainly by code for new materials and the material name being passed in can vary project to project.

Im currently looking at using RegEx to try and match the strings, i'll post back any results

hope its easy enough to understand

Thanks

Hello,

When running our ASP.net application using a chrome browser that submits a PayPal form on body load at run time, a warning message "A cookie associated with a cross-site resource at https://paypal.com/ was set without the `SameSite` attribute. It has been blocked, as Chrome now only delivers cookies with cross-site requests if they are set with 'SameSite=None' and 'Secure'" is getting appeared in Google chrome browser console window. 

The following PayPal form is basically built at run time via code and it is getting submitted. As the form gets submitted, the cookie warning message is getting displayed and then getting navigated to PayPal website

    <html>
      <body onload='document.forms["paypalForm"].submit()'>
        <form id="paypalForm" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
          <input></input>
          <input></input>
        </form>
      </body>
    </html>

I have tried setting the target framework of my project to ".Net Framework 4.7.2" to make use of "SameSite" attribute in the code and made code changes to fix the cookie warning issue. Even after making several changes in the code, i am still getting the warning message in Google chrome browser console window

Can you please let me know the solution in order to fix the Samesite cookie warning message?

This is a DataMemberAttribute in the context of (de)serialization usage issue.

I had the following (and it fails):

[DataMember]
public object Value { get; set; }

And once I realized why - for good reason. First off, what if I passed a FileStream object? That fundamentally is not serializable.

But let's go to something simpler, a DateTime object. Our REST server is in .Net so DateTime & DateTimeOffset are serializable. So if it could handle "serializable" objects then it works great with the .Net client.

But what about the Java, JavaScript, Python, PHP, and every other SWAGGER supported client. What they store is different. Java alone now has about 12 different datetime related object. If the Java client passes an OffsetDateTime, what should a .Net deserializer do with that?

So that leads me to I create a class that has:And for the above the canonical value is a string, but we also need a type because "00123" might be a zip code (string).

[DataMember]
public string Value { get; set; }

public int ValueAsInt { get; }
public DateTime ValueAsDateTime { get; }
public float ValueAsFloat { get;}

And this will work great today. However, in the near future we plan on having complex values. Say employee where he value is their name, birthday, and an address object (so nested objects). Would the above approach be ok where we use the Value class for the birthday and standard declarations for name (string), etc?

And where we know it's a date like the birthday, we can have a ValueDateTime object we use. More specific is good. But where the Value can be anything, that's where we have this big problem.

Is this the best way to handle it?

What we did for the last 6 months - Made the world's coolest reporting & docgen system even more amazing

This is a System.Net.WebRequest question.

I am trying to read https://www.davidthielen.info/files/dave.docx using System.Net.WebRequest. I can read this fine with Chrome. And as you can see in the request settings for me WebRequest object, this should all be good:

But I am getting a 403. Any idea why?

Hey

Im looking at trying to add either a draw line or a custom cursor to the mouse pointer. I am working inside Inventor and what i am trying to achieve requires a visual element that Inventor doesnt provide. They do provide a method of hooking into the mouse cursor by adding a .cur. I looked online to create these manually but they are all small and what i need is more of a custom length each time its used. For example:

I click on a drawing view and i can get the view size X & Y in CM. lets say the width is 75cm. I add 20cm for a space and would like to add a line that is 95cm to the mouse pointer with its hotspot dead center.

Is it an option to create a .cur file from code with the line graphic at a specified length that can be used and either delete it or overwrite it each time?

Thanks

Requirements: Windows 10 1909 Build 18363, Visual Studio 2019 Version 16.6.1

The MSFT documentation on SystemEvents gives a clear example of how to hook SystemEvents into a Windows Service, by creating a hidden Form.  However, following the instructions exactly, I am not able to get any of the SystemEvents to log a message to the Event Viewer.  Does this no longer work?  I am running Windows 10 1909 (Build 18363), using Visual Studio 19 Version 16.6.1.

                this.ResumeLayout(false);
            }
        }
    }
}

When I compile, install, and start the service, then try to do something like change the time, change my desktop background, or change my display resolution, NOTHING HAPPENS!  The last seen event log message is that the "Form loaded".

Any help would be greatly appreciated!
