I am unable to get a modeless dialog box to popup when a Shortcut Menu item is pressed. Here is what I have:

Quoting 

DlgResource.rc

 

Code

IDD_SIMPLEINPUTMENU DIALOGEX 0, 0, 215, 78 STYLE DS_SETFONT | DS_FIXEDSYS | DS_CENTER | WS_POPUP | WS_CAPTION | WS_SYSMENU CAPTION "Foobar" FONT 8, "MS Shell Dlg", 400, 0, 0x1 BEGIN EDITTEXT IDINPUTBOX,38,29,144,14,ES_AUTOHSCROLL | WS_GROUP GROUPBOX "Bar",IDC_TARGETINROUP,25,7,169,44,BS_FLAT | WS_GROUP DEFPUSHBUTTON "OK",IDOK,112,57,50,14 PUSHBUTTON "Cancel",IDCANCEL,51,57,50,14 END

Quoting 

MainStudyFile.cpp

 

Code

#include "resource.h" #include <windows.h> #include "sierrachart.h" SCDLLName("My Studies") HWND g_hwndAddTarget = NULL; // Window handle of dialog box int foo; BOOL CALLBACK FooBarProc(HWND hwndDlg, UINT message, WPARAM wParam, LPARAM lParam) { UNREFERENCED_PARAMETER(lParam); switch (message) { case WM_INITDIALOG: return TRUE; case WM_COMMAND: switch (LOWORD(wParam)) { case IDOK: foo = GetDlgItemInt(hwndDlg, IDINPUTBOX, NULL, FALSE); return TRUE; case IDCANCEL: DestroyWindow(hwndDlg); return TRUE; } } return FALSE; } SCSFExport scsf_FooBarStudy(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { sc.GraphName = "Foo bar study"; sc.StudyDescription = ""; sc.GraphRegion = 0; sc.AutoLoop = 0; sc.FreeDLL = 1; return; } int& r_MenuID = sc.GetPersistentInt(1); if (sc.LastCallToFunction) sc.RemoveACSChartShortcutMenuItem(sc.ChartNumber, r_MenuID); if (r_MenuID <= 0) r_MenuID = sc.AddACSChartShortcutMenuItem(sc.ChartNumber, "bar"); if (r_MenuID < 0) sc.AddMessageToLog("Add ACS Chart Shortcut Menu Item failed", 1); if (sc.MenuEventID != 0 && sc.MenuEventID == r_MenuID) { g_hwndAddTarget = CreateDialogW(NULL, MAKEINTRESOURCE(IDD_SIMPLEINPUTMENU), (HWND)sc.ChartWindowHandle, (DLGPROC)FooBarProc); ShowWindow(g_hwndAddTarget, SW_SHOW); } }

By the way, that is all the code I have. Exactly how it is structured in my files. I'm not sure if that is the proper way to structure it or not. Any guidance will be helpful at this point.

Any help would be appreciated.

I still need help with all of this if anyone experienced would be willing to help in any way.

Hi.
Try create a thread with MessageLoop() instead of creating dialog directly.
You can pass a pointer to s_sc structure to the dialog constructor then.
Maybe it's not a best way, but works fine for me. I'm using tnis set of classes for working with GUI windows coding - Win32++. Header only wrapper around winapi functoins, very nice to remove MFC.

Could you provide a link to the documentation/reference on MessageLoop()? Also, could you provide a small code example of what you're talking about?

OK, after holidays

Main dll *cpp:

 

Code

#include "stdafx.h" #include "TestDialog.h" SCDLLName("Dialog Test") HANDLE m_hThread = nullptr; CMyDialog* TestDlg = nullptr; CWinApp TheApp; static UINT32 __stdcall TestDlgThreadProc(void * pParam) { s_sc* p_sc = reinterpret_cast<s_sc*>(pParam); if (p_sc == nullptr) return 1L; if (TestDlg == nullptr) { TestDlg = new CMyDialog(IDD_DIALOG, p_sc); TestDlg->Create(); TestDlg->ShowWindow(); TestDlg->UpdateWindow(); TheApp.Run(); } _endthreadex(0); return 0; } void StartDialog(SCStudyInterfaceRef sc) { UINT ThreadId = 0; if (m_hThread == nullptr) { m_hThread = (HANDLE)::_beginthreadex(NULL, NULL, TestDlgThreadProc, &sc, CREATE_SUSPENDED, &ThreadId); if (NULL == m_hThread) { return; } else { ::ResumeThread(m_hThread); sc.IsFullRecalculation = 1; } } } SCSFExport scsf_DialogTest(SCStudyInterfaceRef sc) { SCSubgraphRef Average = sc.Subgraph[0]; if (sc.SetDefaults) { sc.GraphRegion = 0; Average.Name = "Average"; Average.PrimaryColor = RGB(0, 255, 0); Average.DrawStyle = DRAWSTYLE_LINE; Average.LineWidth = 2; sc.AutoLoop = 1; sc.AlertOnlyOncePerBar = true; sc.UpdateAlways = 1; sc.FreeDLL = 1; sc.AutoLoop = 1; return; } StartDialog(sc); int len = 30; sc.DataStartIndex = len - 1; sc.SimpleMovAvg(sc.Close, Average, len); if (sc.LastCallToFunction) { TestDlg->SendMessage(WM_CLOSE, 0, 0); DWORD result = WaitForSingleObject(m_hThread, INFINITE); if (result == WAIT_OBJECT_0) { CloseHandle(m_hThread); m_hThread = NULL; delete TestDlg; TestDlg = nullptr; } } }

As for MessageLoop(),
it is windows messaging prosedure, TheApp.Run() returns this one:

 

Code

MessageLoop() { // This gets any messages queued for the application, and dispatches them. MSG Msg; ZeroMemory(&Msg, sizeof(MSG)); int status = 1; LONG lCount = 0; while (status != 0) { // While idle, perform idle processing until OnIdle returns FALSE // Exclude some messages to avoid calling OnIdle excessively while (!::PeekMessage(&Msg, 0, 0, 0, PM_NOREMOVE) && (Msg.message != WM_TIMER) && (Msg.message != WM_MOUSEMOVE) && (Msg.message != WM_SETCURSOR) && OnIdle(lCount) != FALSE ) { ++lCount; } lCount = 0; // Now wait until we get a message if ((status = ::GetMessage(&Msg, NULL, 0, 0)) == -1) return -1; if (!PreTranslateMessage(Msg)) { ::TranslateMessage(&Msg); ::DispatchMessage(&Msg); } } return LOWORD(Msg.wParam); }

Happy coding!
