In the DLL is a dialog window class to call to create it, and make it as a child window (call the function in the first picture, parameter transfer this), the assertions in the create DLL dialog box, as shown in figure 2, excuse me expert how to solve this problem,

Borrow the answer of
If your conversation is created in the dynamic library, should be a dynamic library AfxFindResourceHandle didn't load dynamic library resources, load is exe executable program resources,

CodePudding user response:

Not as a child window before
Direct pDlg - & gt; Create (IDD) do not pass this pointer to the parent window ok

Pass this to conclude the

PDlg - & gt; Create (IDD, this action done in the middle of the DLL

I am not very understand,
You this sentence "if your conversation is created in the dynamic library", emphasizes the dynamic or static links you?
Are implemented in a DLL class, create Dlg parent window just call the create function __declspec (dllexport) passed parent window parameters to his pointer
Reference is a little complicated, can I this problem under the simple explanation

Collapsed in the pop-up dialog box, press the corresponding button to enter debugging press Alt + 7 key to view the Call Stack, namely "the Call Stack" from the inside to the following out of from the inner to outer function Call history, double-click a row to the cursor to the Call of the source code or assembly instruction, don't understand when double click on the next line, until we can read ,

Teacher, I did not understand till the end!!!!!!
The problem in:
Void CWnd: : AssertValid (const)
{
CHandleMap * pMap=afxMapHWND ();
ASSERT (pMap!=NULL);
}
This piece of the MAP table is empty ~ ~ ~

I am in
The CWnd call DLL of create (IDD)

 int CCalculator: : OnCreate (LPCREATESTRUCT LPCREATESTRUCT)//parent window create 
{
If (CBasicWnd: : OnCreate (lpCreateStruct)==1) 
return -1; 

M_Hwd=OpenCalculator (this);//create a DLL child window "-- -- -- -- -- - this transfer out assertion 
return 0; 
} 

 # define DLLEXPORT extern "C" __declspec (DLLEXPORT) 
DLLEXPORT HWND OpenCalculator (CWnd * WND); 

 HWND OpenCalculator (CWnd * WND) 
{
AFX_MANAGE_STATE (AfxGetStaticModuleState ()); 

PTD - & gt; Create (IDD_CALCULATOR_DIALOG, WND); 
HWND HWND=pTD - & gt; GetSafeHwnd (); 

Return the hWnd; 
}

Please check the return values of each function call
