• Smart Device Development wm5 today plug-in dll (possible to use MFC?)

  hi, i'm new to smart device development and i have to develop a today plug-in dll in c++ for wm5. the app will display a tabpage control on the today screen with on-top dialogs showing details. it will show a dialog for user options as well. i know that the dll will depend on dllmain() as its entry point, and i know that mfc will provide its own dllmain(). that means it's quite no possible to use mfc to develop a today plug-in dll unless you copy mfcs80ud.cpp to your project and edit it. that's not what i want because i don't want to edit microsoft provided cpp files and make them local to my project unless it is really necessary. now the questions are: 1. is native c++ the only way to develop a plug-in dll for wm5 today screen my concern ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Fps is at ~60 all the time?

  Hello, I'm total noob with XNA so please bear with me :) In xna beta 2, designer is now gone, so to access IsFixedTimeStep I have to do this in code: public Game1() { graphics = new GraphicsDeviceManager(this); content = new ContentManager(Services); this.IsFixedTimeStep = false; } Problem is that it always shows fps at around 60 no matter what I do - draw some 3d model or just empty screen. I know I'm missing something simple here, please help.. Btw, I'm using one of fps code examples found on this forum, so I don't think problem is in fps code itself. Thanks, ErnisJ IsFixedTimeStep determines whether or not the Update call is made every Xth of a second or run continuously. What ...Show All

• Visual C# PInvokeStackImbalance was detected

  Hi, I keep getting this error when I try to run my project from the IDE.This does not happen when running the exe. The details specify that the Stack Imbalance was detected in a third party dll which I am using. How can I fix this. Thanks, tribal A call to PInvoke function ThirdPartyDll!Namespace.ClassName.NativeMethods::ImageList_DrawEx' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature. It's because a Managed Debugging Assistant has detected an error. Since the error is in a third party dll you have to talk ...Show All

• Visual Basic How do I do this? Threading?

• .NET Development Need help understanding dynamic DLL loading

  Hi all, need some help with dynamic DLL loading. I am trying to create an application that will instantiate a class (from a DLL) at runtime. The type, exposed properties, and exposed methods of the instantiated class are known (inherited from a custom designed class). Using Assembly.LoadFrom([Path]) coupled with Activator.CreateInstance(type, param()) I was able to almost instantiate the class (for some reason I get an parameter error, will explain more). Unfortunatley the LoadFrom() will place a LOCK on the DLL and I am unable to replace the DLL with a newer version even after the application has been closed in the Debugger. The idea is that these dynamically loaded DLLs will be loaded and unloaded wehenever needed (similar to object in ...Show All

• .NET Development Problem with delayed SSL Connections and HTTPWebRequest

  Hello, We have a Windows service that needs to do a simple connect (GET) to an SSL Server periodically. When the service is started, the first request always goes through fine. As long as the subsequent requests are within a short period of time (minutes), they go through fine as well. However, when a longer period of time has elapsed between connections (hours), the connections fail, giving the dreaded : "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.", with an inner exception of "Remote certificate was verified as invalid by the user." Here is a snippet of the code: Dim strConnectURL As String = String.Concat(strURL, " ", strContent) Di ...Show All

• Smart Device Development Why Can not I connect the WM5.0 device by the remote process viewer and remote heap walker?

• Visual Studio Tools for Office combobox in microsoft excel

  Hi, I noticed that you can add a combobox through data/validation in microsoft excel, however when you leave that cell, there will be no longer any indication that the cell has a drop down list. Is there any way to add a combo box in excel with the drop down indicator at all time. thanks The feature you describe is an Excel feature not a VSTO feature. Using VSTO and Visual Studio, you can create a custom Excel application that adds a ComboBox to a spreadsheet. The ComboBox's behavior can then be programmatically controlled. The behavior of the Excel validation list, on the other hand, is entirely controlled by Excel. Cheers, TC ...Show All
