Create an MFC extension DLL in Visual C ++We compiled an example of the extension class and encapsulated it in the DLL to show you this process.Some tested windows programmers gradually release the Windows SDK, however, it is switched to an open environment that provides high-level image extraction for low-level computers in windows. One of the main benefits of t

Although something that can be implemented with a DLL can be implemented with COM, the DLL has many advantages, and it is easier to create. This article discusses how to use MFC to create different types of DLLs, and how to use them. One, different types of DLLs You can use MFC to generate two types of DLL:MFC extens

MFC extension DLL for VC ++ dynamic link library Programming The similarities between the MFC extension DLL and the MFC rule DLL are that the MFC class library can be used inside the t

Afx_manage_state (afxgetstaticmodulestate (); // this parameter is used for status protection during module switching, 1. afxgetstaticmodulestate () points to the current module status; 2. The status of the original module is automatically restored after the current function call ends; 3. It is used to switch the module status when the MFC functions, classes, and resources are called in the DLL. I encounter

You should also switch resources when exporting functions in an MFC extension DLL. In a shared (dynamically linked) MFC rule DLL, before each of the exported functions need to switch resources, in the extension DLL also need, because they are dynamically linked to the

MFC extension DLLs are the same as MFC rule DLLs because MFC class libraries can be used internally within both DLLs, except that MFC extension DLLs and application interfaces can be MFC. The meaning of an MFC extension

When I used to write the mfc dll, I always saw a prompt in the automatically generated code framework. I need to add the prompt at the beginning of each output function.Afx_manage_state (afxgetstaticmodulestate ()). I have never understood the meaning of this, nor have I done it, and the Code also works.Well, it seems like a nonsense. In a recent project, you need to use

Today, we just made a static DLL to be linked to the MFC, that is, "use MFC in a static library", which is used to display a form. Then it can be executed in an MFCProgramCall this DLL file in a.exe to display the form normally. However, after a small change, the DLL is chan

Let's take a look at an example: 1. Create a rule DLL dynamically linked to the mfc dll, which contains a dialog box resource. Specify the dialog box ID as follows:# Define IDD_DLL_DIALOG 2000 2. Create a dialog box-based mfc application that contains two dialog box resources: IDD_UI_DIALOG and IDD_EXE_DIALOG. Specify

How to call com DLL on the MFC Client Some may think this is a very pediatric problem. However, it took me some time and effort to figure it out. OK. Let's briefly talk about how to do this.There are many ways to generate a com DLL. For example, VB, VC ++, and Delphi. Since I only omitted VB and Vc, I just used them as an example.(1)

If you want to write modular software, you need to have a certain understanding of dynamic link libraries (DLLs), I this time in the modification of the previous software, decided to reuse the class and dialog box to do the DLL, the following from a simple example, how to implement the MFC extension DLL Export classes and dialog boxes. First, create an
