问题 I added several existing files (from a VS 2008 Windows CE project) to a VS 2008 Winforms project. For many (but not all) of the forms, I get this err re: the *.resx files: Invalid Resx file. ResX input is not valid. Cannot find valid "resheader" tags for the ResX reader and writer type names. The *.resx files that are fine display like so when I 2-click them in the Solution Explorer: ...whereas those that won't compile with the err msg above display one thing if I 2-click the *.resx file in

问题 In visual studio, I have an error that I didn't have before in Dev-C++: int project = (rand() % 5) + 1 ; int P[project][3]; Compilation: error C2057: expected constant expression error C2466: cannot allocate an array of constant size 0 error C2133: 'P' : unknown size Can you help to understand this error? 回答1: You need to allocate memory dynamically in this case. So you cannot say int P[someVariable] . You need to use int *mem = new int[someVariable] Have a look at this link. 回答2: In C++ you

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I'm trying to create a localized version of a Windows Form in Visual Studio 2008. Following various walkthrought, I set the form property Localizable to TRUE, and set the form language to French. I then edit the

问题 I have done a program to calculate a determinant of a matrix. My program works, but the problem is that it takes long time to calculate, especially for big matrix. Could you tell me how can a perform my program in order to calculate the determinant in the shortest possible time? double Matrice::Determinant(int n) { cout<<"n = "<<n<<endl; int i,j,j1,j2; double det = 0; Matrice tmp(n,n); if (n < 1) { } else if (n == 1) { det = this->get_el(0,0); } else if (n == 2) { det = this->get_el(0,0) *

问题 I have a base User Control. I place Ok and Cancel buttons on the bottom right of the control and anchor them Bottom and Right. I then create another user control that inherits from the base user control. I resize the inherited control (e.g. increase height or width). Throw the inherited control onto the form. Run. The inherited control does not honor the anchor properties of the Ok and Cancel buttons. Here are the exact steps to repro. 1 - Create a new winforms project 2 - Create a base

问题 Are there alternatives to Visual Studio 2008/Visual Web Developer Express for developing ASP.Net applications? 回答1: Microsoft Expression Web also has a limited support for ASP.NET. It will allow you to drop in the web controls and the like, but you'll have to write up your own code behind and compile from the back end unless you go with a Web Site deployment as opposed to a Web Application Project deployment. EDIT: Well, looking at the features in Expression Web 2 (I'm still using 1.0), they

问题 Yesterday Thomas helped me a lot by providing exactly the query I wanted. And now I need a variant of it, and hopes someone can help me out. I want it to output only one row, namely a max value - but it has to build on the algorithm in the following query: WITH Calendar AS (SELECT CAST(@StartDate AS datetime) AS Date UNION ALL SELECT DATEADD(d, 1, Date) AS Expr1 FROM Calendar AS Calendar_1 WHERE (DATEADD(d, 1, Date) < @EndDate)) SELECT C.Date, C2.Country, COALESCE (SUM(R.[Amount of people per

问题 I am adding on to an existing WPF Project, and am running into an odd error. My Toolbox is empty. I am developing in a Windows 7 environment using Visual Studios 2008 run as Administrator. I have created a project from scratch, and the tools were there. However, when I load the existing project, there are no tools in the Toolbox. I do have an element in the UI selected. I fixed this once by going into Tools -> Choose Toolbox Items... -> WPF Components. I then added the tools that I needed.
