Hi, I am quite new to MFC development. I am looking to fix the child dialog inside a parent dialog, currently, I am getting the parent dialog positions and place the child dialog on the top right corner, but each time, when I move the parent dialog, the child dialog never moves. How can I resize it dynamically, or make it move as parent dialog moves. Here is my child dialog generation code.

m_banner=new DialogTest(); if(m_banner!= NULL) { BOOL ret = m_banner->Create(IDD_DIALOGTEST, this); if(!ret) //Create failed. AfxMessageBox(_T("Error creating Dialog")); m_banner->GetWindowRect(rect); int dx = rect.Width(); int dy = rect.Height(); GetWindowRect(rect); rect.left = rect.right - dx; rect.bottom = rect.top + dy; m_banner->MoveWindow(rect); m_banner->ShowWindow(SW_SHOW); } ↧ Search RSSing.com $ 0 0

Here is a snippet of code:

bool CMeetingScheduleAssistantApp::ReadFromXML(CString strFileXML, tinyxml2::XMLDocument& rDocXML) { FILE *fStream = NULL; CString strError, strErrorCode; errno_t eResult; bool bDisplayError = false; using namespace tinyxml2; // Now try to create a FILE buffer (allows UNICODE filenames) eResult = _tfopen_s(&fStream, strFileXML, _T("rb")); if (eResult != 0) // Error { bDisplayError = true; _tcserror_s(strErrorCode.GetBufferSetLength(_MAX_PATH), _MAX_PATH, errno); strErrorCode.ReleaseBuffer(); } else // Success { // Now try to save the XML file XMLError eXML = rDocXML.LoadFile(fStream); if (eXML == XMLError::XML_SUCCESS) { // The XML data was loaded successfully! if (fclose(fStream) != 0) { // There was a problem closing the stream. We should tell the user bDisplayError = true; _tcserror_s(strErrorCode.GetBufferSetLength(_MAX_PATH), _MAX_PATH, errno); strErrorCode.ReleaseBuffer(); } } } if (bDisplayError) { strError.Format(IDS_TPL_ERROR_READ_XML, strFileXML, strErrorCode, errno); AfxMessageBox(strError, MB_OK | MB_ICONINFORMATION); return false; } return true; }

I get a code analysis warning on this line:

if (fclose(fStream) != 0)

warning C6387: 'fStream' could be '0':  this does not adhere to the specification for the function 'fclose'.

I am assuming this is a false positive because we test the return value of _tfopen_s. Isn't that enough?

We are trying to communicate to a host over SSL but the problem is that CInternetSession::OpenUrl Generates exception 12057:

CInternetSession isession;CHttpFile* pFile = NULL;CString httpadrstr = L"https://theadress.com";DWORD dw;char buffer[2048];BOOL bret = TRUE;

try

{isession.SetOption(INTERNET_OPTION_SECURITY_FLAGS, SECURITY_FLAG_IGNORE_REVOCATION);pFile = (CHttpFile*)isession.OpenURL(httpadrstr, 1, INTERNET_FLAG_TRANSFER_ASCII  | INTERNET_FLAG_SECURE, NULL, 0);pFile->QueryInfoStatusCode(dw);switch (dw){case 200:pFile->Read(buffer, 2048);break;default:bret = FALSE;}pFile->Close();}catch (CInternetException* pEx){bret = FALSE;pEx->Delete();}

This code genrates the exception. If i paste the host adress in Opera or Edge it works fine. Any Idea?

Here is another interesting issue. My code:

void CChristianLifeMinistryHtmlView::DoPrintPreview() { HWND HWND_PP, HWND_FG ; TCHAR szClassName[256] ; ULONGLONG t1, t2 ; RECT workArea; ExecWB(OLECMDID_PRINTPREVIEW, OLECMDEXECOPT_PROMPTUSER, NULL, NULL); HWND_PP = NULL ; t1 = ::GetTickCount64(); t2 = ::GetTickCount64(); // Extra line required for 'while' rearrangement. while (HWND_PP == NULL && t2 - t1 <= 6000) // if found or Timeout reached... { HWND_FG = ::GetForegroundWindow(); // Get the ForeGroundWindow ::GetClassName(HWND_FG, szClassName, 256 ); if (lstrcmp(szClassName, IE_PPREVIEWCLASS) == 0) // Check for Print Preview Dialog HWND_PP = HWND_FG ; theApp.PumpMessage(); t2 = ::GetTickCount64(); } if (HWND_PP != NULL) { // AJT V3.01 BUG Fix - showing maximized crops bottom of preview dialog ::SystemParametersInfo( SPI_GETWORKAREA, 0, &workArea, 0 ); ::MoveWindow(HWND_PP, workArea.left, workArea.top, workArea.right - workArea.left, workArea.bottom - workArea.top, TRUE); } }

The code analysis warning this time is:

warning C28183: 'HWND_FG' could be '0', and is a copy of the value found in 'HWND_PP':  this does not adhere to the specification for the function 'GetClassNameW'.

It mentions two things there. But, for the first one, according to the documentation it states:

The return value is a handle to the foreground window. The foreground window can beNULL in certain circumstances, such as when a window is losing activation.

So I assume that NULL is going to be OK in some instances. And I confess I am unsure about the second part of the warning and why it is raised as an issue. My HTML View works. But if this can be fixed I am interested in learning what to do.

Thanks.

I call a function in my DLL to initialize a structure address so the DLL gets the same data. 

When the DLL function runs, I see this:

The value of sp is 0x149a39e0, which looks right.  How come this address is not assigned to LENS1 in the dll?

CString str;

...GetWindowText(str)

str += "more text";

...SetwindowText(str);

Does not work.

...SetCurSel(-1, -1);

...ReplaceSelection("more text")

Does not work either.

All I am getting is the first line of text that I add then all all subsequent lines I add are ignored.

Why?

I'm doing dev / c ++ linux for more than 10 years, but today I have a new job and they ask me to develop on Windows environment with Visual Studio. I'm in the middle of the authorized period of self-training and despite hundreds of websites on about this subject I  am really not comfortable with the notions of managed object, COM, and finally... all the .NET environment ^^ So I am totally lost and no colleague to help me. Today I have to write a DLL that contains a class with its pretty methods, and which creates a custom dialog box in which programs must send text messages.  I specify: programs that use this DLL are written in C ++ MFC, C #, C ++ / CLI, delphi and Python ...  So after several liters of sweat I wrote it in C ++ MFC, to have a dialog and a simple use with the outside. That I thought... I managed to use C#, using the IUnknown interface and a small method to create an instance of my class. In C ++ MFC I use it easily. Where I'm blocked for 3 whole days this is for the C ++ / CLI. And that's where I need you! Clearly I can call a basic method, but I can not create my graphic object and not call the constructor of my mfc class.

I hope you will understand my problem and help me. And I apologize about my english !

For information : I use the same target platform and same toolset. DLL is working really fine with C# and C++/MFC.

Thanks by advance,

Back in 2010, I learned about move semantics when they were first added to VC++. Back then, move ctors/assignment operators were not automatically generated, but this seems to have changed a dozen times and I have better things to do than keep up with the standards committee's whims.

What are the current rules for generating move ctors/assignment operators and how are they implemented in VC++? Also are there any differences between VC++ 2013 and 2015?

The following code has worked on a number of Windows 10 machines, but I have just found one where it does not work because the registry of this particular copy of windows 10 does not have a SERIALCOMM folder.

The system COM ports must be listed some where so, if not under SERIALCOMM, then where?

void CSerialPort::GetCOMPorts(CStringArray &strarrayCOMPorts, CWnd *pWnd) { CRegKey regkey; DWORD dwI = 0, nBuffSize = BUFF_SIZE; char szKeyName[BUFF_SIZE], szKeyVal[BUFF_SIZE]; LONG nCode = ERROR_SUCCESS; CString strKeyVal, strTemp, strResponse; UINT nCOMPort = 0; CSerialPort SerialPort; memset(szKeyName, 0, BUFF_SIZE); memset(szKeyVal, 0, BUFF_SIZE); if (regkey.Open(HKEY_LOCAL_MACHINE, "HARDWARE\\DEVICEMAP\\SERIALCOMM", KEY_READ) == ERROR_SUCCESS) { //LONG WINAPI RegEnumValue(_In_ HKEY hKey, // _In_ DWORD dwIndex, // _Out_ LPTSTR lpValueName, // _Inout_ LPDWORD lpcchValueName, // _Reserved_ LPDWORD lpReserved, // _Out_opt_ LPDWORD lpType, // _Out_opt_ LPBYTE lpData, // _Inout_opt_ LPDWORD lpcbData); do { nCode = RegEnumValue(regkey.m_hKey, dwI, szKeyName, &nBuffSize, NULL, NULL, NULL, NULL); if (nCode != ERROR_NO_MORE_ITEMS) { nBuffSize = BUFF_SIZE; regkey.QueryStringValue(szKeyName, szKeyVal, &nBuffSize); nBuffSize = BUFF_SIZE; strKeyVal = szKeyVal; strTemp = strKeyVal; strTemp.Delete(0, 3); nCOMPort = atoi(strTemp); if ((nCOMPort >= 1) && (SerialPort.Open(strKeyVal)) && (SerialPort.isIrrigationController(strKeyVal))) { SerialPort.Write("id#"); if (SerialPort.Read(strResponse, 2000) > 0) { strarrayCOMPorts.Add(strResponse + " (" + strKeyVal + ")"); } } SerialPort.Close(); dwI++; } } while (nCode != ERROR_NO_MORE_ITEMS); } else AfxMessageBox("Cannot access the Windows registry...", MB_OK); } ↧ $ 0 0

Hi, VS experts out there?

I am new to VS.  I am using html, php and MySQL.   I would appreciate that someone guides me on the possibility of

displaying on monitor, data looking like a checking account bank statement.    Is one of the prerequisite  accessing database, using VS script?   Is the form setup and display by way of C++?  

Thanking you in advance!

Dear VS experts:

Please guide me to approach the best way of developing an app and displaying form on a monitor?

Input be from database and the form profile can be like a bank checking account statement, listing daily credit & debit.

Thanks in advance!
