[python-win32] Registering COM servers doesn't work out of the box any more
I recently tried to install a COM server written in Python and ran into a small problem. The procedure I used was this: 1. Install Python 3 using the standard Windows installer, as Administrator, for All Users, adding Python to the path. 2. pip install pypiwin32 3. Run my script for registering the COM server, which calls win32com.server.register.UseCommandLine. This didn't work, and the reason turned out to be that the InprocServer32 registry was just the filename of the dll, rather than a full pathname. When I changed it to an absolute pathname, the server worked fine. The standard win32com code for server registration seems to be assuming that pythoncom.dll and winctypes.dll have been installed in C:\Windows\System32. However, pip doesn't put them there, and I get the impression that installing all DLLs there is no longer considered best practice. I found an old sourceforge bug report about this: https://sourceforge.net/p/pywin32/bugs/393/ which suggests a one-line change to win32com\server\register.py to address this problem, but it was closed with works-for-me. Am I right that using a relative pathname for InprocServer32 is no longer the right thing to do?

If nothing else, by inserting a print statement into the program at the point just after it has retrieved the password. Keyrings allow a user to keep his or her passwords secret from *other* users. The OP seems to want to keep the *user* of the password from being able to know it, which is fundamentally impossible.

[python-win32] Printing coordinate system problem
I'm wrestling with printing support for PyGUI on Windows. I'd like to set up the coordinate system during printing so that (0, 0) is at the corner of the paper, so that I can arrange for the margins to have predictable sizes. However, the device context I get from calling PrintDlg() seems to be set up so that the origin is at the corner of the printable area of the page, which is smaller by some amount that depends on the printer being used. If I could find out the limits of the printable area, I could correct for this, but there doesn't seem to be any straightforward way of getting this information. It doesn't seem to appear anywhere in any of the structs returned by PrintDlg(), and I can't find any call that might extract it from the device context. Am I missing something? Surely this an issue that most applications that print have to deal with. How do they do it? -- Greg ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

The device on the corner of your desk with the paper in it is not a printer, it is a printing device. Yes, I know. I'll be happy if I can somehow find out what the driver for whichever printer has been selected in the PrintDlg box thinks the printable area is for the selected paper size. If that doesn't match what the actual printer uses, that's not my problem. :-) Delving a bit further, it looks like I may be able to find out via GetPrinter() and GetForm()... I'll try an experiment shortly. Using Crystal Reports, a rather expensive commercial product which uses Windows very well, I designed a very fancy Purchase Order form, which I tested on three or four different Windows printers.

[python-win32] RichEditCtrl scrolling doesn't work properly
I'm trying to create a PyRichEditCtrl with scroll bars. I can get scroll bars to appear using the appropriate style flags in CreateWindow, but they don't entirely work. Clicking on the scrolling arrows causes the text to scroll, but the position of the thumb doesn't get updated to match. Can anyone point me to a piece of example code that shows the minimum necessary steps to get this to work? I've looked at the editor example that comes with pywin32, but the details are hidden under several layers of abstraction, making it hard to tell what's essential. Also, it seems to use a RichEditView/RichEditDoc combination instead of a RichEditCtrl. Does this make a difference? Is it possible to get a plain RichEditCtrl to scroll properly, or do I need to use a RichEditView? The code I'm currently using looks like this: import win32con as wc, win32ui as ui win_style = wc.ES_MULTILINE | wc.ES_WANTRETURN win = ui.CreateRichEditCtrl() win.CreateWindow(win_style, (0, 0, 100, 100), parent_win, 0) flags = 0 if 'h' in scrolling: flags |= wc.WS_HSCROLL if 'v' in scrolling: flags |= wc.WS_VSCROLL win.ModifyStyle(0, flags) win.ShowWindow() -- Greg ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

Using Times, for example, it seems to be using the

so that Times comes out as Shldr -- except that it
uses the widths of the original characters for positioning.

Turns out I *sort* of have a font called Times... I've got Times Bold, Times Italic and Times Bold Italic, but no plain Times! Times New Roman works fine, though, and it seems that the same is true of all the other fonts for which there is a full set of variations.

[python-win32] PyCSlider notification messages
I'm having trouble getting notification messages from a Slider control. According to MS, a Slider is supposed to send WM_HSCROLL messages to its parent window when the user changes it, but this isn't happening. I can get WM_HSCROLL messages from a normal scroll bar, but either the Slider isn't sending them or I'm somehow failing to intercept them. Is HookMessage the right way to catch these? Or is there some other trick to this that I'm missing? -- Greg ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
[python-win32] PyCScrollView with no PyCDocument?
Is there any way of creating a ScrollView without needing a Document? I just want a scrollable user-drawable area, but CreateView insists that I supply a Document. What's more, the only way to create a Document seems to be to use a DocTemplate, and the only way to get one of those is to use a resource. But I don't have any resources. -- Greg ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

Re: [python-win32] PyCScrollView with no PyCDocument?
Well, I think I've found a workaround. The following hack seems to create something looking enough like a PyCDocument to keep it happy while creating a PyCView: dummy = win32ui.CreateRichEditView().GetDocument() The result of this appears to be a PyCDocument that's wrapping a null pointer. The fact that CreateView accepts this suggests that there's really no need to supply a document at creation time as far as the C++ level is concerned. I can't find anything in the MS docs to say there's any such need. Looking at the source, you seem to be doing some very strange things. In the PyCView constructor, first you're hacking around protected members to stuff the CDocument pointer into the m_pDocument member. Then in CreateWindow you're taking it out again and putting it in the CCreateContext. I don't know why you can't just leave all this alone at creation time, or at least make the document argument optional, and expose the AddView method of CDocument as a way of setting the document afterwards. -- Greg ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
[python-win32] Focus lost when switching windows
The following program creates a FrameWnd with an Edit control in it. If I select some text in the control, then switch to another window and back again, the Edit control has lost the keyboard focus.

[python-win32] Confused about PreTranslateMessage
I'm having trouble understanding how PreTranslateMessage is supposed to work. According to M$: Return value: Nonzero if the message was translated and should not be dispatched; 0 if the message was not translated and should be dispatched. and according to the pywin32 docs: The result should be a tuple of the same format as the msg param, in which case the MSG structure will be updated and TRUE returned from the C++ function. If all of that is true, I don't see what the purpose is of updating the MSG, since it's just going to be ignored when TRUE is returned. But in any case it doesn't seem to be working -- the original message gets dispatched anyway, regardless of what I return from my PreTranslateMessage method. So I'm totally confused at this point. Should I be able to prevent the original message from being dispatched, and if so, how do I go about it? -- Greg ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
Re: [python-win32] Finding attached object?
Mark Hammond wrote: Hrm - m_pMenu (and m_pSubMenu) is *supposed* to return a PyCMenu object - what are you seeing? They're returning a PyCMenu, but not the object that I have attached to the PyCMenu. This seems to happen automatically in some other places, e.g. ui.GetFocus(). If m_pMenu behaved that way as well, I wouldn't have had a problem. While on the subject, there's something I'm a bit confused about. According to the MS docs, when you destroy an HMENU that has sub-menus attached, the sub-menus are destroyed as well. This suggests that the only reasonable way to attach a PyCMenu as a sub-menu is to Detach its menu handle first. If that's true, then the PyCMenu object isn't much use any more, so you might as well throw it away, and not getting the attached object from m_pMenu probably isn't so much of a problem. But what happens if a PyCMenu object returned by m_pMenu or m_pSubMenu gets deallocated before the parent menu? It seems as though it will end up destroying an HMENU that it doesn't really own, and stuff up the menu that contains it. On another topic, another thing it would have really been handy to have access to is the m_bAutoMenuEnable property of CFrameWnd. PyGUI has its own scheme for managing menu item enabling, and MFC's one just gets in the way. If I could turn it off, it would save me a lot of hassle. -- Greg ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
Re: [python-win32] Finding attached object?
Mark Hammond wrote: Apparently not from Python. It would be easy to add, If you do happen to add this, another thing you might want to investigate is why PyCCmdUI isn't automatically doing this when you read the m_pMenu property, as seems to happen in most other places if you call a method that returns a wrapped MFC object. but I guess that doesn't help you much now (or parse the repr() and use ctypes to de-ref the pointer, then wash your hands ;) I was hoping to avoid having to use ctypes:-(. I'm working around it for now using weak refs and a global dict to make my own reverse mapping, but it's disappointing having to do this when the information is hidden in there all along. -- Greg ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

There are actually two possible ways it could go. I have a partial implementation contributed by one of my users based on ctypes, but it has some issues, and programming at the raw win32api level is a bit much for me to cope with just yet. So I'm working on an alternative implementation based on the mfc layer of pywin32. This does mean an extra dependency, but I consider pywin32 to be fairly standard equipment and not too much of an imposition to require. Also it will work with older versions of Python that don't come with ctypes. It's coming along nicely -- tests up to 07 are working well enough. It's a bit disappointing that buttons don't play fair with respect to colour customisation, but not a serious problem.

[python-win32] OnCtlColor not working?
Has anyone successfully used the PyCWnd.OnCtlColor virtual function to change the appearance of a control? The program below tries to use it to set the colour of the text in a PyCButton.

[python-win32] Python COM: Automatic wrap/unwrap?
I'm creating a COM server in Python that will have one main class, with methods that create and return instances of other classes. I've found that I need to use win32com.server.util.wrap and unwrap on these objects when they pass over a COM connection. This doesn't seem very convenient, especially for methods that can be called either via COM or internally from other Python code. It seems that the basic Python types are wrapped and unwrapped automatically when needed. Is there some way of extending this mechanism?
