问题 Is the VB6 to .NET upgrade wizard included in VS2008 better than the one in VS2005? UPDATE: I ran the same VB6 code through both upgrade wizards and VS2008 produced far less reported issues in the ugprade report. The upgrade wizard in VS2008 must be an improved version. 回答1: Both VS2005 and VS2008 use the same convertion utility. 来源： https://stackoverflow.com/questions/8194038/which-is-better-vb6-to-net-converter

问题 I have written some image processing program using OpenCV 2.1 I received a error during linking, related to "projectname.ilk" file.(message said VS is trying a non-incremental linking). So I triied rebuilding the project. The initial message went away, but now VS never completes "Linking". It prints "1>Linking..." and stays that way. What might be the problem? Thanks 回答1: If clean build fails to remedy, try eliminating /LTCG on the link and whole program optimization in c++. There have been

问题 I have a form with a few text-boxes and a Grid-view. There is this one text-box called "Inward Number", whose text-changed event fires all the time. When i want to fire another control's event, it simply fires the text-changed event of the Inward Number text-box. This happens with all of the other controls. Can someone please help? protected void txtInward_No_TextChanged(object sender, EventArgs e) { a = 'A'; NewRow(); } I have used the correct names, but still this error occurs. <asp:TextBox

问题 I have a huge set of .vcproj files (~200) stored in different locations. I have a list of these files with full paths. How can i automatically add them to the solution file(.sln) ? UPD: I'm looking for existing tool/method. 回答1: Here's how I'd do it: Create and save a blank solution to insert the vcproj files into (File->New Project->Other Project Types->Visual Studio Solutions->Blank Solution) Create a VS macro which adds a project to a solution, saves the solution, and exits. Try the

问题 Currently I have this implementation of the meyer singleton: class ClassA { public: static ClassA& GetInstance() { static ClassA instance; return instance; } private: ClassA::ClassA() {}; // avoid copying singleton ClassA(ClassA const&); void operator = (ClassA const&); }; Now I need some improvements to getting this code thread safe in C++-98 and VS-2008?! Thanks! PS: What is unclear? You see the tags visual-studio-2008 and c++-98 -> so the target OS is Windows! I also don't understand why I

问题 I have a set up where the assembly is published to the GAC after each build. But My application uses the old dll all the time. After build the new dlls are created in a new folder. The folder names are 7.1.7573.0_ d516cb311 and 7.1.5000.8888 _d516cb311. The second folder being the latest. It seems(from the folder name) my current code is publishing old dll. Is it the reason my application is using old dll? If yes What will I have to do so that currect assembly is published? Edit: In the web

问题 I like (bool) way more, but it generates warnings. How do i get rid off the warnings? I have code like: bool something_else = 0; void switcher(int val = -1){ if(val != -1){ something_else = (bool)val; }else{ something_else ^= 1; } } Should i just do it like everyone else and use '!!' or make it somehow hide the warning messages when using (bool) ? Or is '!!' actually faster than (bool) ? I would like to use (bool) and so i have to hide the warning, but how? Edit: Visual Studio 2008 i am using

问题 i've been working on a C++ project for some time now in VS 2008. Until recently, upon terminating my application the output window would show if i had any memory leaks. however, a few days ago i noticed it stopped showing this valuable information. i also tried throwing some printf() around, but the output window isn't showing that either. i'm guessing i changed a preference somewhere, but i can't seem to find it. all the output shows now is which dll's it has loaded/unloaded. any ideas?

问题 Alright, so what I'm attempting to do here, is select from a datatable all the rows that match two variables. First, I queried a SPList into a datatable. The datatable has two columns, Client ID, and Model Details. Here's some of the code, so hopefully you can get an idea of what I'm attempting. //These are contained within a foreach loop, so will be different through each //iteration through. int iClientID = gdbData.GetClientID(iJobNumberID); string strModelDetails = xeApprovalUpdate
