问题 I need to go sit together with the network infrastructure guys to see why suddenly SQL connection errors like below occur. As a preparation, please provide input why this error can occur, and which things we could try at the application and/or infrastructure side to circumvent it. The error occurs when starting an application from a network share. The error does not occur when copying the files locally and starting it locally. The error is always reproducible. A couple of weeks ago (before I

问题 I want to pin a WPF window on the desktop (it should be a desktop gadget). I know you can do this by setting the parent handle of the WPF window to the handle of the "progman" window. But this does not prevent the hiding of the WPF window when "Windows + D" is pressed. There must be another way do to this. The new desktop gadgets in Windows 7 are not hidden when "Windows + D" is pressed. How did the MS developers achieve this? 回答1: I think your best bet would be to create a Gadget and host

问题 The following piece of source does run nicely with Windows up until vista. With Windows 7 (and the new .net 3.5) it always produces an out of memory exception, when I try to load a raw image file from my Nikon D90. Some might say "loading nef's is not supported", but it did run nicely up until vista, only Windows 7 broke it, so I'd disagree. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System

问题 I have an application that compiles ok (mingw) and runs ok, however the edit control that is created has scroll bars but the vertical scroll bar doesn't do anything. The same executable works fine on WinXP. Also, the edit control has both vertical and horizontal scroll bars, the horizontal works just fine, but vertical does not. The vertical scroll bar is visible and clickable, but nothing happens... Following code is used when creating the edit control: HWND hwndEdit = CreateWindow(TEXT(

问题 Currently I have an c++ console application running on Win7/AIX/Linux. In the application I use getmaxyx to get the dimensions of the window. getmaxyx(_window, _rows, _cols); On the windows platform i need to play around with the (properties)(layout) options of the running app, to get the screen maximized. That is a bit of a pain. Thumbing through the documention yields nothing of value. lines: Specifies the number of lines the "screen" will have. Directly equates to LINES. There is no

问题 I am trying to make a desktop application that will be hidden but will display only after a time interval. I am trying to set Visible =false at window load event but it still displays. 回答1: For WinForms applications I have found that the easiest way to control the start-up visibility is to override the SetVisbileCore method. Here is a simple example, the form will show after 5 seconds using System; using System.Windows.Forms; namespace DelayedShow { public partial class Form1 : Form { private

问题 Given a legacy desktop application in Windows Form , managed code (a mix of C# and VB projects) running on .NET Framework 3.5 (which can't be migrated to newer .NET for reasons beyond the scope of this question), how GRADUALLY transition the code from GDI+ to Direct2D ? Or possibly to Direct3D? Another constraint is that the resulting application work on Windows 7 , but we will migrate to Windows 8 or Windows 10 if that is the only way to get this to work. (The impetus is bugs in GDI+
