    <p>I have two <code>.exe</code>s. They need to use each other's functions at run times. One is dilogue based application <code>.exe</code> and other one is main application <code>.exe</code>. Now main application need to use dialog based applications function. But while compiling it could bot able to locate the existance of <code>called function</code> because unavailability of <code>dialog based applications .lib</code>. Because if i make dialog based application to <code>.lib</code>, then the program will fail at run time. So, I need to make call one <code>.exe</code> to other <code>.exe</code>. When I am trying call,</p> <pre><code> TestClass tc;/* Call dialog based application exe functions*/ tc.MyTest(); </code></pre> <p>It is throwing errors like</p> <pre><code>1&gt;CallExe.obj : error LNK2001: unresolved external symbol "public: __thiscall TestClass::~TestClass(void)" (??1TestClass@@QAE@XZ) 1&gt;CallExe.obj : error LNK2001: unresolved external symbol "public: void __thiscall TestClass::MyTest(void)" (?MyTest@TestClass@@QAEXXZ) 1&gt;CallExe.obj : error LNK2001: unresolved external symbol "public: __thiscall TestClass::TestClass(void)" (??0TestClass@@QAE@XZ) </code></pre> <p><code>Main application.cpp</code></p> <pre><code>int _tmain(int argc, _TCHAR* argv[]) { STARTUPINFO si; PROCESS_INFORMATION pi; TestClass tc;/* Call dialog based application exe functions*/ tc.MyTest(); // set the size of the structures ZeroMemory( &amp;si, sizeof(si) ); si.cb = sizeof(si); ZeroMemory( &amp;pi, sizeof(pi) ); LPCTSTR szCmdline = (LPCTSTR)(TEXT("Dialog.exe")); // start the program up if(!CreateProcess(TEXT("D:\\Rasmi's\\Personal\\Visual Studio\\Dialog\\Debug\\Dialog.exe"), // the path argv[1], // Command line NULL, // Process handle not inheritable NULL, // Thread handle not inheritable FALSE, // Set handle inheritance to FALSE 0, // No creation flags NULL, // Use parent's environment block NULL, // Use parent's starting directory &amp;si, // Pointer to STARTUPINFO structure &amp;pi ) // Pointer to PROCESS_INFORMATION structure ) {cout &lt;&lt; "Unable to create\n";} // Close process and thread handles. CloseHandle( pi.hProcess ); CloseHandle( pi.hThread ); return 0; } </code></pre> <p>In <code>Dialog.exe</code></p> <pre><code>TestClass::TestClass(void) { } TestClass::~TestClass(void) { } void TestClass::MyTest() { cout &lt;&lt; "This is my Test Class \n"; } </code></pre>

    1. COwhy not put the dialog used in both applications in a separate library you reference from both exes?

    2. COThis cannot work, a DLL is required. Which will probably "fail at run time" as well if you don't address the core problem.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
