问题 How is the app.config binding in .Net? Let's say if I have an application project referencing a class library project. The code ConfigurationManager.AppSettings["MySetting"] in the class library project will read the value from app.config from the application project. Is my understanding correct? So how about if we have 2 class library project, let's say A and B while A is referencing B. So will ConfigurationManager.AppSettings["MySetting"] read the value from app.config in project A? Thanks

问题 I am using the longblob data type to insert image but it gives error. I want to insert image from picture box to mysql database. 回答1: I have here a c# implementation but you can use a c# to VB.Net converter In the aspx file: <asp:FileUpload runat="server" ID="fuPersonPicture" /> <asp:Button runat="server" ID="btnPhotoUpload" Text="Upload" OnClick="btnPhotoUpload_Click" /> In code-behind: protected void btnPhotoUpload_Click(object sender, EventArgs e) { byte[] rawData = new byte

问题 I am debugging C++ using VS2008. The watch window used for debugging stores all the dynamic values in various objects, arrays, variables etc. I want to copy the entire contents on this watch window into a file so that I can forward the debugging context to someone else. If I just selct all (CTRL + A), and paste the contents in a file then i wont get the branching information (i.e info like an object might have various sub-objects in it). Can anyone kindly let me know how to do this in VS2008.

问题 I am experiencing some annoying behavior with Visual Studio .NET 2008. We have created a base form, and a base grid derived from Infragistics UltraGrid. In the base form, we have set some properties like colors, font size, etc. 1. We create a new Windows Form, (i.e. DerivedForm) 2. We change the inheritance to BaseForm, by simply adding a using statement and changing the inheritance in the class definition. 3. The IDE at this point copies all of the property settings you would see in BaseForm

问题 Currently I'm working on a project for school, and I can't solve this. I have a form, and if you insert to it English characters, it works fine and the info is inserted into the DB, but if I insert Hebrew characters (@form), nothing happens. Now, to clarify, I have tested 100%, that even when I insert Hebrew characters, it gets into the 'if' block which contains the sql insert. The whole project is managed with Visual Studio Web Developer 2008. If I manually insert hebrew written values, the

问题 I have an application developted with Visual C++ 2008 Express Edition under Windwos XP, which runs propertly on one computer, where the default langaunge is set to English.

问题 The following method throws this exception System.IO.Stream)(ms)).ReadTimeout threw an exception of type System.InvalidOperationException' This is the method: private static byte[] ImageToByteArraybyMemoryStream(Bitmap bmp) { using (MemoryStream ms = new MemoryStream()) { bmp.Save(ms, bmp.RawFormat); return ms.ToArray(); } } however, this error doesn't occur all the time. I'll try to explain in short what happens: I load a bitmap from a file, display it and store it in Dictionary<int,Bitmap>

问题 I am implementing a header file "IVideoPlayer.h" and I have created an abstract class "IVideoPlayer". class IVideoPlayer { public: // Initialization virtual bool Load(const char* pFilePath, bool useSubtitles = false) = 0; virtual bool Start() = 0; virtual bool Stop() = 0; //.... }; And the functions of that are defined in file "VideoPlayer.cpp" #include "stdafx.h" #include "IVideoPlayer.h" #include <dshow.h> HRESULT hr = CoInitialize(NULL); IGraphBuilder *pGraph = NULL; IMediaControl

问题 Is there a way to find ILDASM.exe from Visual Studio 2008? I know the location "C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin", but I want it through Visual Studio 2008. 回答1: I'm not sure what you mean by "wanting it through Visual Studio", but you can easily add it to the Visual Studio Tools menu with the "Tools -> External Tools" dialog. 回答2: If you have the SDK: C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin Personally, though, I'd use .NET Reflector instead... I tend to
