---

Preface

VS edition ：VS2019
QT edition ：Qt5.12.3(msvc2017_64)

One 、 Effect display

1. Before adding version information VS After adding version information

2. Before getting version information VS After obtaining version information

Two 、 edition 、 Copyright information settings

• stay VS in , Right click the item name -> add to -> resources ;
  
• In the pop-up window , choice Version-> newly build ;
  
• In the pop-up version explorer, you can set the version number 、 Corporate name 、 Copyright 、 Set the software name and other information ;
  
• Exit Explorer after saving , Regenerate the executable , Executable file （.exe） The version is displayed 、 Copyright and other information .
  

3、 ... and 、 Version information acquisition and display

• You need to add version resources to get files VersionUpdate.h;

VersionUpdate.h file

#pragma comment(lib, "version.lib")

#include <QObject>
#include <windows.h>
#include <tchar.h>

class VersionUpdate
{
    
public:
	static QString VersionUpdate::GetVersion()
	{
    
		int nMaxPathName = 4096; // Max length of file name/path
		TCHAR* pBuffer;
		UINT nItemLength;
		void* pData, * lpBuffer;
		QString sVersion;
		DWORD dwInfoSize, dwHandle;
		VS_FIXEDFILEINFO* pFileInfo;

		// Get the file path and name
		pBuffer = new TCHAR[nMaxPathName];
		GetModuleFileName(NULL, pBuffer, nMaxPathName - 1);

		// Get File Version Info size
		dwInfoSize = GetFileVersionInfoSize(pBuffer, &dwHandle);
		if (dwInfoSize > 0)
		{
    
			pData = new TCHAR[dwInfoSize];
			if (GetFileVersionInfo(pBuffer, dwHandle, dwInfoSize, pData))
				if (VerQueryValue(pData, _T("\\"), &lpBuffer, &nItemLength))
				{
    
					pFileInfo = (VS_FIXEDFILEINFO*)lpBuffer;
					sVersion = QString("%1.%2.%3.%4")
						.arg(pFileInfo->dwProductVersionMS >> 16)
						.arg(pFileInfo->dwProductVersionMS & 0xFFFF)
						.arg(pFileInfo->dwProductVersionLS >> 16)
						.arg(pFileInfo->dwProductVersionLS & 0xFFFF);
					// Calculate the product version as a number, you can delete the next statement if you don't need it.
					DWORD dwProductVersion = (pFileInfo->dwProductVersionMS >> 16) * 1000 +
						(pFileInfo->dwProductVersionMS & 0xFFFF) * 100 +
						(pFileInfo->dwProductVersionLS >> 16) * 10 +
						(pFileInfo->dwProductVersionLS & 0xFFFF) * 1;

				}
			// Delete the data buffer
			delete[] pData;
		}
		// Get rid of the allocated string buffer
		delete[] pBuffer;
		return sVersion;
	}
private:
};

• stay main.cpp Add these sentences to the code ;

#include "ApplicationVersionUpdate.h"
#include <QtWidgets/QApplication>

// Get the version number 
#include "VersionUpdate.h"
#define AppTitle (QString)("ApplicationVersionUpdate_V"+VersionUpdate::GetVersion()) 

int main(int argc, char *argv[])
{
    
    QApplication a(argc, argv);
    ApplicationVersionUpdate w;
    // Set the display content of the status bar 
    w.setWindowTitle(AppTitle);   
    w.show();
    return a.exec();
}

• Run the project , The window frame status bar displays the configured version information .
