问题 I want to render 4 millions triangles in my windows based software which is written in Visual Studio C++ 2010 (Build in Release Mode). When I render 3.9 millions triangles, the total RAM memory consumed by the software is 400MB. But when I try to render 4 millions triangles (just 100K more), the system gives me an error. For Example: Point *P = new (std::nothrow) Point[nb_triangles]; //==> "(std::nothrow)" is for catching the run time memory allocation error. (Point is X, Y, Z floats) If(P ==

问题 Does anyone know if there is a way to "transform" specific sections of values instead of replacing the whole value or an attribute? For example, I've got several appSettings entries that specify the Urls for different webservices. These entries are slightly different in the dev environment than the production environment. Some are less trivial than others <!-- DEV ENTRY --> <appSettings> <add key="serviceName1_WebsService_Url" value="http://wsServiceName1.dev.domain.com/v1.2.3.4/entryPoint

问题 Using Visual studio 2010 I got problems when double-clicking, for example a config file (*.config). Visual Studio would open but give me a error message about parameters. If I simple try to drag and drop a file that Visual Studio usually can read in to it, the icon will give me the "not possible icon"?

问题 The path to the project I need to check out is displayed in the TFS Source Control Explorer this way: Handheld Development Development HDP HDP Or, in the "Source location:"this way: $/Handheld/Development/Development/HDP/HDP The code that I need to check out and work on is in that last folder. So what do I need to do before right-clicking that second "HDP" folder and selecting "Get Latest Version"? IOW, do I need to create an empty folder or folders first for TFS to find, or will it create

问题 Whenever I have Dim catID as integer And I use this in a query like this: cmd.CommandText = "select * from categories where parentid='" + catID + "'" I get: Conversion from string select * from categories where p to type Double is not valid. Why is it so? The parentid datatype in sql is integer . 回答1: Try cmd.CommandText = string.Format("select * from categories where parentid='{0}'", catID) if parentid is a numeric field in your database then you'll need cmd.CommandText = string.Format(
