winforms-interop

I have a WinForms based app with traditional MDI implementation within it except that I'm hosting WPF based UserControls via the ElementHost control as the main content for each of my MDI children. This is the solution recommended by Microsoft for achieving MDI with WPF although there are various side effects unfortunately. One of which is that my Ctrl+Tab functionality for tab switching between each MDI child is gone because the tab key seems to be swallowed up by the WPF controls. Is there a simple solution to this that will let the Ctrl+tab key sequences reach my WinForms MDI parent so that

I'm trying to make a custom window frame for my form using DWM. The platform is C# WinForms, Pinvoking DWM. Following the MSDN article on making custom window frame with DWM , the main steps are next: Remove standard frame (non-client area), returning 0 in answer to WM_NCCALCSIZE message Extend the frame into client area using DwmExtendFrameIntoClientArea function I handle WM_NCCALCSIZE message in the next way: protected override void WndProc(ref Message m) { switch (m.Msg) { case WM_NCCALCSIZE: if (isDwmWindowFramePaintEnabled() && m.WParam != IntPtr.Zero) { m.Result = IntPtr.Zero; } else {

What I am trying to do is add an "Email To..." button to a winform client that opens a new outlook mail window and attaches a file so the user can forward it. I can get the outlook integration working just fine if outlook is not already running. This is a C# .NET 4.0 winforms app, using the Outlook 14.0 interop library, against Outlook 2010 32 bit running on windows 7 64 bit machine. I have the app already compiled to x86 for other reasons so I doubt its a 32/64 bit issue. Here is my code: // Connect to outlook and create a new mail item var app = new Outlook.Application(); var ns = app

I have a C++ DLL that is creating an instance of a COM object that's implemented in .NET. Under many circumstances this works fine, but under certain circumstances, it hangs the application, and I see it stuck with the following call stack (this is just the part underneath the level of my DLL's code): ntdll.dll!_NtAlpcSendWaitReceivePort@32() rpcrt4.dll!LRPC_CASSOCIATION::AlpcSendWaitReceivePort(unsigned long,struct _PORT_MESSAGE *,struct _ALPC_MESSAGE_ATTRIBUTES *,struct _PORT_MESSAGE *,unsigned long *,struct _ALPC_MESSAGE_ATTRIBUTES *,union _LARGE_INTEGER *) rpcrt4.dll!LRPC_BASE_CCALL:

I'm hosting a WPF UserControl in a WinForms container. Now, I want to be able to theme/skin the UserControl. To do this, I've got several resource dictionaries that define the "skins." When my app starts up I create a "new System.Windows.Application()" so that Application.Current exists. To change the theme the old skin is removed and a new skin is merged into the Application level resource dictionary at runtime. However, this does not change any of the dyanamically referenced resources in the UserControl. I tried this in a straight WPF application and it worked just fine. Am I missing

I have a WPF application and I want to play flash movies in it. I used the WInforms active X control as described in this link It worked partially, but now whenever I run the application it crashes saying "InvalidActiveXStateException" does anyone have an idea how to solve this? I would recommend adding a WebBrowser control to your WPF application and allow IE to load the URL of the Flash Movie directly; which in turn would load the Flash Plugin. You will need to build your WPF application as x86 only for this to work on x64 Windows. I found a solution. You can use a AxShockwaveFlash. see this

I've attached a small example about the issue. How can I hide the control box completely during Maximize and Minimize the Borderless Form using System.Windows.Forms; using System.Runtime.InteropServices; using System.Security; using System.Threading; namespace TalkTime { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private const int WM_NCPAINT = 0x0085; protected override void WndProc(ref Message m) { int message = m.Msg; switch (m.Msg) { case WM_NCPAINT: { Thread.Sleep(100); return; } } base.WndProc(ref m); } protected override CreateParams CreateParams { get
