plugin – Unreal: Where should I put a DLL to be copied when it is compressed or compressed?

I am currently using the FPaths::ProjectPluginsDir() directory to store a custom DLL for Unreal. However, when I build or compress the project, I have to manually create a Plugins folder and copy the DLL in this file.

Is there another folder that would be a better directory to store my plugin in order to have my DLL copied automatically when it is compressed or compressed?

hosting – dll stimulsoft using installed fonts on the server

As I understand your question, when I assume you want to automatically install the missing / mandatory fonts on your Plesk server?
In any case, such automation depends entirely on the operating system used. Therefore, additional information is needed to provide a solution.
If it's a pure PLESK solution, then I suggest you contact their support. They are generally very flexible and competent in my experience.

design – Is it bad to inherit from a class in a different DLL in my case?

I make a graphical application. I have a DLL that contains classes belonging to the render stream. My rendering engine can draw classes inherited from IShape, which is in the dll. My goal is to inherit this class outside of the dll, then pass it to the rendering engine for it to draw. In this way, I can reuse this dll and create custom and different shapes in each application I create.

dll
 ├── Renderer  (has a function like void Draw(IShapre shape); )
 └── IShape
app
 ├── Rectangle : IShape
 ├── Main (which calls renderer.Draw(new Rectangle(...)); )
 └── other classes

Is it a bad design? What are the other options to achieve this?

Call the C ++ DLL containing the C # DLL in Java (JNA) – invalid memory access

j & # 39; uses JNA in Eclipse to call a C ++ function. This function is implemented in a DLL. That works well.

The problem is that I need a function that is only available in C #but I need it in the middle of the C ++ function. That's why I want to call a C # function in the C ++ function.

But that throws a & # 39; invalid memory access & # 39; Fault.

I have tried it with and without settings. No entry, no exit and nothing to do in the method. Nothing works.

In one c ++ console application the call is not a problem, I can use parameters and call Consoles of Console.WriteLine ()

Calls in C ++:

First test: Static-Method

MyNamespace :: MyClass :: MyFunction ();

Second try: instantiate an object

MyNamespace :: MyClass ^ MyObj = gcnew MyNamespace :: MyClass ();

Class in C #:

First test: Static-Method

using the system;

namespace MyNamespace
{
Public class MyClass
{
static public void MyFunction ()
{
//Console.WriteLine("Whoopydoo ");
}
}
}

Second try: instantiate an object

using the system;

namespace MyNamespace
{
Public class MyClass
{
static public void MyFunction ()
{
//Console.WriteLine("Whoopydoo ");
}
}
}

I'm waiting for a static method to be callable.
And to instantiate an object should also work.
Why it does not work?

Thank you!

php – How to operate a remote dll?

I have a problem related to running a remote dll on a windows computer.

I have a dll registered in all client computers (windows) of my network and a .NET application hosted on a server on my network.

there is a POST request that will receive the IP address of the client as a parameter and the application will execute a remote call to the DLL installed on the PC of the IP address transmitted in the request.

As a result, the program for the open DLL will already be open in the client PC (IP address passed in the POST request).

I've already used PHP with XAMPP, I could check that it works locally, although XAMPP restarts a few times (I do not know the real reason yet). One solution would be to locally install on each client an xampp network server with a php application receiving the requests and running the dll locally, but would be impractical given the amount of PCs available on the network. I've already seen that it would be possible to make a remote call in this php documentation FAQ, but without success. I start at .NET with C # because I think being native (Windows) will be easier / more efficient for getting results, but I have not yet found a plausible way to work remotely.

Has anyone experienced this experience or do you have any idea how to manage a remote DLL with .net, java, php or some other qqr technology?

Error in the DLL in Apache

I have installed wampserver 3.1.7 in Windows 8.1 64 and apache displays the following message.

The entry point of the Isupper procedure in the dynamic link library could not be located

I have tried with newer versions of wampserver and the error persists. What changes is the word "isupper" which in version 3.1.7 is "islpha".

I've already downloaded this pcre.dll file from the https://pt.dll-files.com/pcre.dll.html site and replaces the original pcre.dll installation in the same directory as indicated in the picture. But still not successful.

When you view the Apache error log, the following message appears:

[28-May-2019 17:35:07 UTC] The Apache variable "$ {INSTALL_DIR}" is not set.

Can any one help me?

SQL Server – SQL database scripts in exe or dll format

I am working with SQL Server 2016 and will need to send scripts generated in some versions to our client, so that they can install the package in UAT and Production.
I would like to send the scripts in dll or exe format, so that they can not see their content. This is possible?
Do I need third-party applications? If yes, which ones?

hash – MD5 Checksum and DLL injection

The simple fact of checking the MD5 hash of a DLL may not be secure enough because MD5 does not stand up to hash collisions and can no longer be considered safe. An attacker could inject malicious code into a DLL and modify it in such a way that the malicious DLL returns the same MD5 hash as the "real" DLL.

As @schroeder mentioned, you will probably want to use a signature-based approach in which only DLLs signed with an approved and known certificate (for example by the main developer) are allowed.

However, this leads to some new problems, such as certificate management, trust management, and so on.

Windows Installer – How to Explicitly Remove dll During Majorupgrade Using Wix Toolset

We are trying to deploy an update of our product containing an updated DLL. This dll also has a version number, so normally the installer should be able to see it and replace the old dll.

The Windows Installer program is only interested in the first three numbers when checking the version number. However, in this case, the updated version number has the same appearance, except for the fourth number. For example, if the previous version is 1.0.0.12, version 1.0.0.20 is selected. The installer then sees them as the same version and does not replace the file. In this case, I have no control over version numbering, and since we include many dlls, this could happen again in the future.

How can we make sure the installer replaces the file no matter if the version number is the same?

After looking for different solutions, I tried to tell the installer to remove the file during the installation process. I do not want to delete all the files if not necessary. Until now, I have tried the solution presented in the included code snippet. The removefile element is new in this version of the installation program.





The expected result is that the old dll is replaced by the new one. However, after installation, the old is still there and no news.

2010 – DLL missing for workflow

When trying to access http: //[domain]/sites/Home/_layouts/wrkmng.aspx I am receiving an error regarding a missing DLL in the asp.net folder. I'm browsing the folder and the DLL is actually not there.

The missing DLL is: App_Web_wrkmng.aspx2a428413.44q7ajjl.dll.

I had this error when accessing "Workflow" from the site collection site settings (the "Workflow Settings" link located just below "Workflow"). work "works perfectly). I think I have already visited this page, so I do not think it has been that way all the time.

  1. What would make a dll disappear?

  2. Are the file name numbers related to my instance of SP? As, I can not download an App_Web_wrkmng.aspx.xxx.xxx.dll file right?
