wndproc

is there a way I can stop the horizontal scroll bar from ever showing up in a listview? I want the vertical scroll bar to show when needed but I want the horizontal scroll bar to never show up. I would imagine it would have something to do with WndProc? Thanks You could try something like this, I used in a project once and it worked: [DllImport ("user32")] private static extern long ShowScrollBar (long hwnd , long wBar, long bShow); long SB_HORZ = 0; long SB_VERT = 1; long SB_BOTH = 3; private void HideHorizontalScrollBar () { ShowScrollBar(listView1.Handle.ToInt64(), SB_HORZ, 0); } Hope it

If I have a console application with a handle to it set up like so; HWND hWnd = GetConsoleWindow(); Then how do I set up a new wndProc for the window? I tried using SetWindowLong(hWnd, GWL_WNDPROC, (LONG)conProc); With conProc being defined as LRESULT CALLBACK conProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam) { switch(msg) { case WM_NCHITTEST: return HTCAPTION; } return DefWindowProc(hWnd, msg, wParam, lParam ); } But it doesn't work and says "Error code: 5 - Access is denied" on GetLastError() I understand that it's pretty difficult to modify the console application like this, since

Please guide me how to use this WndProc in Windows Forms application: private IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled) { if (msg == NativeCalls.APIAttach && (uint)lParam == NativeCalls.SKYPECONTROLAPI_ATTACH_SUCCESS) { // Get the current handle to the Skype window NativeCalls.HWND_BROADCAST = wParam; handled = true; return new IntPtr(1); } // Skype sends our program messages using WM_COPYDATA. the data is in lParam if (msg == NativeCalls.WM_COPYDATA && wParam == NativeCalls.HWND_BROADCAST) { COPYDATASTRUCT data = (COPYDATASTRUCT)Marshal

To communicate with a certain service, I have to override the WindProc . and receive window messages. However, when the form is minimized, I get no longer any message. I know that it has to be like that, but is there a workaround for this? I don't want to have a hidden form which stays always open... jrequejo I've also needed to solve a similar problem recently. Abel's answer set me on the right direction. Here is a complete example of how I did it, by changing a normal window into a message-only window: class MessageWindow : Form { [DllImport("user32.dll")] static extern IntPtr SetParent

I'm trying to write a simple application in Java that will communicate with an USB device. The USB device is made by me using a Microchip Microcontroller. The communication is rather simple, since the USB device is from the HID Class, arrays of 64 bytes are exchanged between the computer and the device. My program finds the device based on the product ID and the vendor ID, can write and read 64 bytes, but now I would like to detect when the device is connected or disconnected from the computer. As I've seen in a C# program provided by Microchip as an example application, the WndProc method is
