When I step into CMainFrame::OnAlohaHowAreYou(), I found m_pDoc is NULL. If I remove the split views and make CMainFrame::OnCreateClient() like below, then there is no problem.
I have been working with both Chris Mander's MFC grid and the Ultimate Grid.
See for details:
The Ultimate Grid Beginner's Guide By The Ultimate Toolbox, 25 Aug 2007 : [URL] ....
MFC Grid control 2.27 By Chris Maunder, 6 May 2010 : [URL] ....
Both of these grid controls work nicely in a SDI CView windows. But when I create a split window using CSplitterWnd and the following code in an attempt to create a split window with a CListView and and a CView using this code:
Code: // in CMainFrame.h // Attributes public: CSplitterWnd m_wndSplitter; //.. // in CMainFrame.cpp //.. BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
[Code] .....
The grid in the CView window appears but is frozen in both instances. I suspect there is some notification necessary to for the grid to send and receive messages from the split CView window, but I cannot figure out how to implement this notification.
Unfortunately, even a demo application would be too large to append, but for anyone that is interested, the split method is encapsulated in the code I've presented here and the implementation of both grid controls is well explained in the links provided.
I have been struggling to read a certificate in windows store from C++ DLL, but its not happening. from console application I can but when same code built as a DLL and tried to access from a separate console application. I think its not going to windows store to read the cert.
I have an MFC program created from the app wizard. It is an MDI program, reading/writing text files using Serialize. I can read the document and know that the entire document was read into my buffer without any errors. This was verified by compaing the number of bytes read with the file length.
How do I get the document to display in my main/child window?
How do I read the document from the window so I can save it back to the file?
I am using Visual Studio 2010 with WindowsXP 32 bit. when i placed break points in my solution and trying to debug then i am getting THE BREAKPOINTS CAN NOT BE HIT NO SYMBOLS HAVE BEEN LOADED FOR THIS DOCUMENT issue.
I am developing a program that needs auto start at windows startup. For that I need to add Registry entries. Also the program needs to read some registry keys. What are the functions i need to do these.. Simply I need to
check if the startup key already exists add a new key if it doesn't exist read a key values
Is it possible to use a CFormView as the main view without using document support. IE pointing CWinApps m_pMainWnd to the CFrameWnd derived MainFrame and attaching the CFormView from there. It does not seem to be working and I was wondering before I waste any more time on the solution if it is even possible. I know it is an easy solution if I create a true SDI application however I have no use for documents in this application.
I quite often use an ide written in assembler: RadAsm3[URL] .....
It has a menu item to explore current path. I have used other ide's that have a similar feature but:
The one in RadAsm3 will activate a current Explorer window if the current path is the same as the one requested. All others open a new Explorer window.
I would like to implement the RadAsm3 approach using Visual Studio 2013 Community c++ as my host compiler for testing.
I tried to get the title of current windows but it appears ShellExecute "explore" does not produce a conventional window???
Screen Splitter will allow main screen to be split into two or more sections. It will be useful for the active program's window to be resized properly to one part of the screen. Using this utility, User will be able to do a split system desktop into two or more areas....
I tried to do this with _spawnl(), but first of all I'm not sure how to properly ask for the path to iexplore.exe, as I'm sure it will change every time MS gets a whim to move it. I know there's a GetWindowsDirectory() call, but that's not where IE resides (its in "C:Program FilesInternet Exploreriexplore.exe" in XP, Lord know where on win 7 or 8).
Also, even temporarily hard coding the path to make it launch with spawnl(), I can't seem to get my html document to display. I know the path to that is right (since I put it there ).
I am trying to make an add-on to IE. This add-on doesn't have any tool bar or any UI.
I am just taking the details of currently loaded HTML page. Basically it is for manipulating one dialog box. I want to get access to the DOM COM interfaces of the dialog box.
Since it doesn't have any button I didn't impliment IOleCommandTarget. I implemented only IObjectWithSIte.
My RGS file contain following in addition to my COM related entries
HKLM { NoRemove SOFTWARE { NoRemove Microsoft {
[Code]...
But I couldn't see my add-on working or even not loading to IE.
Find the attachment. change the file extension *.lct instead of *.txt. I like to read ASCII Data into Hex, Example : Data "A" as "41" (Refer the jpeg image). How is possible?
I have some trouble with DLL. I created a dll with function
double square(const double * args)
and then in my application defines
typedef double (*MyFunct)(const double *args);
I use LoadLibrary and GetProcAddress to get the function address and cast it to MyFunct. Everything works fine except that when I pass a double *, for example 0x08800350, to the DLL function, the argument becomes totally something else, for example, 0x0aa00460.
I have no clue what happens to the argument value.
I am having a strange problem trying to display a dialog from a UI thread. The dialog simply fails to display. I have a function DisplayFlashBox(), which creates the UI thread:
CUIThread* CIMUIHelper:: DisplayFlashBox(const CString &sMessage, const int nInstrumentUID) { CUIThread *pThread = new CUIThread(); pThread->SetString(sMessage); pThread->SetInstrumentUID(nInstrumentUID); pThread->CreateThread();
[Code] .....
The dialog doesn't display. When I tried debugging, I found the OnInitDialog() method of CIMFlashBox class doesn't actually return. Very strange. I tried calling the DoModal() method instead of Create, but doesn't display the dialog either.
My MDI Project(VC++2010 Professional) is unable to catch errors ,though I return ,try catch block. So I developed simple dialog based application .Placed one button on Dialog and on its click written following code
Collapse | Copy Code void CMFCExecDlg::OnBnClickedButton1() { try { int j = 0; int i = 10/j; } catch(CException * e) { MessageBox(_T("Hello"),_T(""),MB_OK); } }
But still program control does not come in catch block it simply gives error. I tried all child classes of CException but no use.I think there will be some setting in Visual Studio. How to handle exceptions
I have main thread that creates an WebBrowser2 COM object. and i want to invoke JScript functions on it from another thread. i try to use GIT but still doesn't work for me.. there is a problem with marshal WebBrowser2 for JScript?
I'm trying to append data to a CFile using FILE* But when execute the application, it always give error saying "No such file or directory". I can actually see the file created but it just keep giving error "No such file or directory".
Is the file being lock or the file just created so it can not be find by fstream(FILE*)? or the file mode is wrong?
Attached is the printscreen of the FILE* pointer. the pointer is evaluated as bad pointer. Why the FILE* pointer not able point to the file being created?
What happens is, after having called the collisionDestroy-function and the program tries to execute the nest loop in the outer for-loop, it all crashes with the text "Expression: vector iterator not decrementable", which I understand is because the iterator will have already become useless. The question is: know this, how do I fix it? I can't seem to get a hang of it.
Here's the collisionDestroy-function (the collisionReaction does nothing but sets a few local variables):
void Enemy::collisionDestroy(std::vector<Sprite*>& sprites) { for (std::vector<Sprite*>::iterator iter = sprites.begin(); iter != sprites.end(); iter++) { Enemy* tmp = dynamic_cast<Enemy*>(*iter); if (this == tmp && collisionType == 3 || collisionType == 1) { sprites.erase(iter); break; } } }
