• Visual Basic Opening files

  Can someone please tell me how can I open one file from one command button Thanks, Xico you can use a StreamReader to read the file contents, or you can also use My.Computer.FileSystem.ReadAllText. Example: Dim theFileContents as String = My.Computer.FileSystem.ReadAllText(" filename.txt ") this would read the entire file contents to a string variable. it depends on how you want to read the file, either in string or as raw bytes. to use a StreamReader, import the System.IO namespace then: Dim theStreamReader as new StreamReader(" FileName.txt ") Dim theFileContents as String = theStreamReader.ReadToEnd() theStreamReader.Close() both pretty ...Show All

• Visual Studio Team System Create macro for editing a projects code analysis settings

  Hi everyone, I am working in a solution which contains numerous projects all of which need to adhere to the same code analysis settings. Instead of having to manually change the settings in each project which is obviously very time consuming, I would like to create a macro which when run, would get the selected project and update the code analysis settings which would be pre-defined inside the macro. This way all I need to manage is the macro functionality instead of each project individually, then when a setting needs to be changed I can update the macro then run it against each project. I have tried to record a macro which does this but it doesnt seem to be able to record the actual setting changes. It records the fact that I h ...Show All

• .NET Development .Net 2.0 threading: calls to Join(), after calling stop(), nerver return.

  Hi, I have recently converted our .net 1.1 project to .Net 2.0. One big issue that I am running into, and still don't have a clue of, is the our code for terminating a thread is no longer work. We have code that starts a thread and then kills it later. When killing it, we just call stop() then join() and it worked fine under .net1.1. But now it is not, after converting to .net 2.0. The join() never return. The app is just hang. Currently, I am just skip the join() and just call stop(). I know this is not safe but I don't have an option. What should I do to make it right Thanks. Feng Use Thread.Abort() to kill off the thread. More cleanly (much more cleanly) is to signal the stop request with a ...Show All

• Visual C++ CButton Events in MFC?

  Hello I just made a little simple app (because I just started last night) that has a button (CButton) with no events and a text box (or CEdit...) and a Static label (CStatic). Now, with that done and working, I'm content (remember, I started last night!) Anyways, my name for CButton is "cb", CEdit is "ce", and CStatic is "cs", all without quotes. Now, I would like so that when cb is pressed, cs will contain the string that was input from ce. How can that be done Please, explain step by step. If you don't want to explain the whole thing, just show me the code, I'll eventually find out. Thank You Keehun Nam Here is my current code: //hello.cpp #include <afxwin.h> // Declare the application class class CHel ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Game Math 101: Changing the magnitude of a vector?

  I find myself needing to change the magnitude of a vector quite often, and end up writing a lot of code that looks like: v1 = Vector2 .Multiply( Vector2 .Normalize(v2), 250.0F); Is there a better way That just seems awfully inefficient. It only gets worse when I want a particular magnitude vector in the opposite direction: v1 = Vector2 .Multiply( Vector2 .Normalize( Vector2 .Negate(v2)), 250.0F); Or inverting the Y-axis of the thumbsticks: acceleration = Vector2 .Multiply( Vector2 .Normalize( Vector2 .Multiply(gpt.Left, new Vector2 (1, -1))), 800.0F); Please, help a noob out... Matt exal is correct, it dawned on me later: Keep your direction and speed seperate, then multiply the ...Show All

• Visual Studio Team System Advice needed: delete old builds using a Task(?)

  I have the following. A build type called "Nighly Build" that is scheduled to run every night. It will drop the output on a shared folder on a server in the following structure: \\server\drops\ProjectA\Nightly Builds\ However after a couple of weeks there will be a lot of nightly builds in this folder. I was wandering what would be a good practice to only keep the Nightly Builds of the last week and delete the ones older than one week Should I add this as a custom task to the "Nightly Build" Build Type Or should I use a batch file or script file and run it on scheduled intervals using the Windows Scheduler Any advice is appreciated or how do you guys deal with this Hello Jason, thanks for the fast reply.

• .NET Development Hot to log each method being executed?

  Hello, I Would like to attach to a thread and log each method i being executed. I'm guessing i should listen to the CLR activities to do so. I have access to the pdb files if needed. how can i do so Thanks, Eran. Hi, There are profilers for .NET out there which perform the action you need. The ones I know of are SpeedTrace, and in CompuWare's DevPartner they have a product that does it too. If you want a simple/free one - that's what I'm trying to create... I remember there is some example in MSDN magazine that includes a working tracing profiler, and also one is supposed to be included in the Visual Studio 2005 SDK. You can also try looking at the CLR Profiler examples in MSDN magazine, such as http ...Show All
