kandi X-RAY | Cview Summary
CView is a web-based comparative viewer for mapping data, including genetic, physical and cytological maps, that is part of the SGN website but that can also be installed and adapted for other websites. In addition to viewing and comparing different maps stored in the SGN database, the viewer allows users to upload their own maps and compare them to other maps in the system. The viewer is implemented in object-oriented Perl, with a simple extensible interface to write data adapters for other relational database schemas and flat file formats.

Pass an actions object, instead of an array, so the code can map the update / updateMany according to the original action.

So it class Cpr111View, you have to keep your Figure member by pointer, or by refernce.
In order to avoid having to manually manage the object, you should use a smart pointer like std::unique_ptr (or std::shared_ptr if you need to share ownership):

Answered 2021-Mar-20 at 06:24You can use the GetPathName() member of the CDocument class (as mentioned in the comments). You can then manually set your main frame window's text by overriding the OnMDIActivate() member function (the handler for ON_WM_MDIACTIVATE) in your MDI Child window class.
Something along these lines:
QUESTION
I need some guidance on how to add a drop down list from an array of data after the read info from the MP4 Tag data is parsed. The mechanism I'm using is 100% operational, this is a creature feature addition. The MP4 tag I'm working with is Genre using the ID3V1 standard. There are 191 choices. The way my app was inherited, there are 2 columns, property/value and multiple rows. All of that works. The Genre tag was setup willy nilly so you could basically type whatever and it would store it. I want to remove that and have the 191 elements in the array to choose from using the drop down list. Part of the loading process is that it will pull in whatever was in the MP4 file. So, I want the user to be able to leave as is (most likely tagged by something that supports ID3V2), or select from the populated 191 elements in the dropdown list.
The object looks like this information.h:

Answered 2021-Mar-23 at 20:20You should not use a plain old C-style array if you do not have a strong reason to. Use a
std::vectorinstead. You don't even need to indicate the[size]. The same goes forchar *. Use aCStringor astd::stringinstead.
QUESTION
ANSWER
Answered 2021-Jan-30 at 07:44If the ulterior motive for SetParent is to keep the dialog in front of the view then the following might work (or it might not, depending on UI specifics). If, however, the reason is to clip the dialog to the parent view, then this won't help, though it still attempts to explain why.
Main issue here is an inconsistency in how Windows applies visual styles to (descendents of) child windows, or rather does not do that. The issue is not confined to VC++ or MFC, and has been noted [1], [2], [3], [4] (the last link is an open case on dotnet/winforms but also references MFC). Because of this issue, re-parenting the dialog as a child of the view "loses" the theming.
One additional complication here is that the window in question is a dialog, and dialogs are owned windows. Just calling SetParent changes the parent of the dialog, but leaves the owner in place. This goes against the rule that A window can have a parent or an owner but not both. Also, SetParent requires that the style bits be updated to remove WS_POPUP and add WS_CHILD instead. However, neither clearing the owner nor fixing the style bits changes the styling behavior once the dialog is made a child of the view.
The alternative is to change the owner of the dialog, instead of its parent, in which case the visual styles do in fact get applied. This keeps the dialog in front of its owner in the Z order, though it does not clip it to the owner area. The caveat, however, is that the owner must be a popup or overlapped window, so it cannot be set to the view itself, which is a child window, but instead to its closest popup/overlapped ancestor. In UIs with a single top-level window, this often means the one and only main window.
Sample code is below, with some comments inlined, and the #if 0 part that's not working.
QUESTION
I'm working on an MFC app. I have a class inheriting from CWinApp which tries to open an AfxMessageBox inside its InitInstance function.
When the AfxMessageBox function is called, no message-box is visible, but I hear a Windows bell sound. If I press Alt, the message box appears. Why isn't the AfxMessageBox appearing immediately?
This question mentions a similar issue, but the answer only refers to the non-MFC function MessageBox, not AfxMessageBox which is what I'm using:
MFC MessageBox Not Showing at Top Of All Windows
Update 1I'm working on a minimal reproducible example, but it's tricky because this is part of a large application with poor encapsulation.
In my app, it appears that a call to the function ProcessShellCommand() is causing AfxMessageBox to stop working. However, calls to AfxMessageBox work correctly both before and after ProcessShellCommand in a newly-created MFC application.
It looks like some consequence of calling ProcessShellCommand is causing AfxMessageBox to behave differently, but I'm not sure how to identify all the consequences of calling ProcessShellCommand. When I'm debugging, the particular call to ProcessShellCommand includes a filename, so the file-open command is causing the app's CView to be launched.
In the OnInitialUpdate code for my CView-inheriting class, AfxMessageBox functions correctly. The best transition point I can identify between AfxMessageBox working, and not working, is when the CView's OnInitialUpdate function returns from it being called by ProcessShellCommand.
It seems that m_pMainWnd is NULL before the call to ProcessShellCommand (while AfxMessageBox is working as expected), and non-NULL after the call to ProcessShellCommand.
Based on this discussion:
Why would a message box be not displaying?
, I tried printing out the message-queue contents before and after the call to ProcessShellCommand. Before, the message-queue only contains a single message. Afterwards, the message-queue printout loop is full of WM_PAINT and it never terminates until I press Alt. This makes me think that I'm running into a message-pump-related issue rather than something related to e.g. visibility state.
---------- More observations ------------
It looks like the call to AfxMessageBox stops inside win32u.dll; I determined this by hitting the 'pause execution' button while waiting for the message-box to appear. Here's the call-stack and debug screenshot:
...ANSWER
Answered 2020-Dec-14 at 22:36It turns out that my CWinApp had a CFrameWnd class that I had forgotten about; I was focusing too much on the CView class.
In the CFrameWnd class, in the BEGIN_MESSAGE_MAP block, there was an ON_WM_TIMER(). I removed this from the message-map to test, and the AfxMessageBox() worked as expected.
When I create a fresh SDI application, there is no ON_WM_PAINT() in the message-map block, so I think this may have been added incorrectly. The class itself does not implement OnPaint(), so I guess this caused some unhandled WM_PAINT messages to be floating around.
It's a bit surprising that this doesn't lead to a compiler error; as I understand it, having ON_WM_PAINT() only makes sense if there's a corresponding OnPaint() function.
