• Windows Forms How to implement Cut Copy Paste

  Hi, I am using different controls in application like text box, numeric text box, list box, combo box and many others. There is a requirement to give cut, copy and paste for these. Do we have a common code or list of properties which needs to be used in each control for implementing cut, copy, paste I am using some htird party controls (infragistics), so it will be great if the solution takes care of those controls as well. Any help in this regard is appriciated. Thanks in advance.

• Visual C# Closing a form before opening another

  Hi, I am trying to develop a simple application. I have a login Screen and on successful login the main screen. Now when the login is a success, I want to close the login form and show the main form. P.S. 1. login form is the startup form 2. I do not want frmLogin.Hide() 3. when I try frmLogin.Close() before frmMain.Show()..flags error (I guess this is logically correct, but then whats the work around ) Please suggest the way in which i can accomplish this. Thanks in advance Rather then try to open one form from another it might be worthwhile to consider having them both be at a sibling level of responsibility... that is to say you might try opening the login form from Program.cs and then if it has done the desired work and returns t ...Show All

• Visual Studio 2008 (Pre-release) LINQ behind a web service - basic problems

  Hi all. I want to use LINQ with a web service. My SQL2005 db is built and I've run through the 'getting started ' lab tutorial substituting my db - works great! Now I've created a new web service project using LINQ and I'm running into problems. First, I created a LINQ website to see what references I needed and to inspect web.config for any peculiarities (added system.codedom compiler stuff and set my web references equal) I used SQLMetal against my db and added the resulting file into my project. I then created a private variable of the type listed at the top of my SQLMetal generated file. Next I newed the variable within Sub New() once I pulled the connection string out of web.config. Everything good so far I think. ...Show All

• Visual Studio Debugger highlights wrong line, steps over code without executing it

  I stumbled across some rather odd behaviour in the debugger this morning, and it took me a while to realize just exactly what was happening. I've tried to distill the problem down to a compact test case: int somefunction(int x, int y) { if (x == y) { try { x++; // or whatever, doesn't matter } catch (SomeCustomExceptionClass &) { return x; } } x--; return x; } // calling code: somefunction(1,2); If I put a breakpoint on the line "if (x == y)", I can verify that x does NOT equal y, so I would expect the contents of the if block to be skipped entirely. However, hitting F10 to step will cause the debugger to highlight the "return x" line inside the catch block inside the i ...Show All

• SQL Server How to compare SQL server stored procedures from two separate databases?

  Is there a straight forward way or a tool to compare SQL server database objects, such as stored procedures located in separate databases Well, the way that I always do it is to use the RedGate SQL Compare tool. www.red-gate.com . It works very nice and will compare everything, including permissions. There are other ways, and Buck Woody (who I have seen around the forums) has an article here that covers it pretty well: http://www.informit.com/guides/content.asp g=sqlserver&seqNum=210&rl=1 ...Show All

• .NET Development Programmatically determine calling method at execution time?

  Without using StackFrame, how might one go about determining the method that called the current method I need this for logging but do not want to use StackFrame since it has difficulties outside of IDE environment. Looked and looked - no can find. For example, method A and B each call method C. From method C, I want to be able to log who the parent method was that called me. Thanks. Thanks guys - nothing like one more 2 by 4 across the head to get me thinking straight. Yes, indeed Nobugz's code does work, inside & outside the IDE. I guess I will have to parse the StackTrace.ToString to get just the file name and file line number, unless you know a better way. Thanks again for not giving up o ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. If my screen is white....?

  This might be a common problem, and i hope there is a simple explanation for it. But when i run my XNA program and all the graphics, which in this case was trying to be a map, is white, and only partially drawing some stuff. Anyone have ideas about why Any and all help is appreciated I haven't seen this reported by anyone else in the XNA forums before. This thread should probably be moved there so that you'll be more likely to get some help from one of the many XNA gurus there. This could be specific to your video card or you could be doing something in the code. Here's a couple of questions to get started troubleshooting this. When you make a new Windows XNA game and run it, do you get the wonderful cornflower blue screen When you ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How to monitor microphone input level?

  I'm using VB.net with Framework 2.0. How to monitor the mic level of the default soundcard I would like to be able to set a threshold value (0-100%) and when the mic level is greater than that a message box would appear. It would be important that the detection would be fast (with as short delay as possible) and consume CPU resources as little as possible. Is this possible without DirectX SDK I found some code in VB6 and C but could not translate them in VB.net. Thank you! With the DirectSoundCapture interfaces you can retrieve input sound from the default input device set on the Windows Multimedia options. Then you can read the input results from there and compare them against the threshold that you wan ...Show All

• Visual Basic How to verify files exist... kinda...

  Hello, I'm trying to verify that each file in a list exist. I can successfully read the text file (which contains the list of files) into an array. (Each containing one filepath.) Each path has quotes around it and I have easily removed them. I then created an array and put the file path to every file (in the specified directory) into each dimension. My problem now is, I need a way to compare the two lists, verifying that each file that exists is in the other list. So I suppose that I am not looking for a way to verify files exist but rather that each file that does exist is in my list. Understand I have considered multiple ways of doing this but they have either failed or I have found that they are not what I am looking fo ...Show All
