Is there a way to keep getting Windows messages while the UI-thread is suspended?

Hi: I've searched newsgroups and various archives, including MSDN & MFC sources, but at this point failed to locate an accurate and simple implementation of WndProc function for MSWindows window objects. Something like: class BaseWindow { virtual LRESULT WndProc( HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam);

Hello: I am encountering a very weird issue with MDI child, Overriden WndProc function and hidden form. Basically, the application has two forms, Form1(parent form), Form2(Child form), Form2's WndProc method is overriden, if the message is CLOSE message, just hide the form. I first initialize and show the child form, then close it by clicking the Close(X) button, the overriden WndProc method gets invoked, and the form is hidden. Then

How can a WndProc be created inside a component? Currently I have a WndProc in my frmMain. It looks for WM_DEVICECHANGE messages for connection and removal events for a USB/Serial device. My frmMain uses a component to communicate with a USB/Serial device. I would prefer that this component handle the WM_DEVICECHANGE messages internally and only fires events to my frmMain when my USB device connects or disconnects. In case anyone...

Hello from example from web i did a little code to avoiding columnHeader resize. this code seems to work well, but when I put a 'normal' ListView on the same Form than my overrided ListView it seems to stop working. if I'm resizing 'normal' ListView ColumnHeaders, then I can resizing ColumnHeaders of my overrided ListView. If I don't resizing 'normal' ListView ColumnHeaders, then resizing of my overrided ListView ColumnHeaders is...

Hello all; I'm trying to create a UI that's a little atypical. In the main form's Paint event handler, I draw an image on the form - this is what I want to by my "real" UI. I turned off the form border, and set the form's background and transparency key to be the same value. As you know, because of this there is no sign of the form, just the image I painted. So far, so good. Since the form border - and hence the title bar - is...

Here's one that should probably have the sub-heading "I'm sure I asked this once before, but ...". Two users are both looking at the same data, from a database. One user changes the data and commits it. How does the other user get the updated view without polling for changes? Is there some sort of callback mechanism that can be set up on the dataset or connection? TIA

I've constructed a user control inherited from ListView so I can handle and respond to scrolling events (to keep 2 listviews scrolling in sync). My user control includes an Overrides of WndProc (I've attached the code at the end of this mail). Is it possible to 'disable' this override until I need it - it's just when I populate the ListViews this sub is called repeatadly. What I'd like to do is populate the listviews and then 'enable'...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends, With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Hello I'm a network technician in training and I need your help. I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs. The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols. I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
