Visual C# Error highlighting
Hello, I've been working with NetBeans IDE (Java) for quite some time and now I'm learning C#. What disturbs me alot in the Visual Studio 2005 IDE is, that non-syntax errors that would lead to a compiler error are not highlighted until I compile my source code. For example if I'd return an integer although the return type of my method is void, the IDE wouldn't highlight that error until I'd try to compile the source. That's quite annoying to me since NetBeans IDE always did that and I'm used to it. Now my question is: Am I missing an option Is there a way to activate it Thanks for any help! The IDE simply doesn't do the sort of semantic analysis that is required to catch these errors before compilation. ...Show All
SQL Server Max Worker Threads setting in X64 system.
Hi All, As we know, the default max worker thread in SQL 2005 is 0. The default value for Max worker threads, 0, allows SQL Server to automatically configure the number of worker threads AT STARTUP. http://msdn2.microsoft.com/en-us/library/ms187024.aspx However, what's the actual max worker thread while the "max worker thread" option is configured as 0 Is it the one list in this table Number of CPUs 32-bit computer 64-bit computer <= 4 processors 256 512 8 processors 288 576 16 processors 352 704 32 processors 480 960 This table is got form the above article.

Visual C++ The com component problem when upgrading from vc6 to vc2005?
When I upgrading a vc6.0 project into vc2005, there is the following error:" Error 31 error C2039: 'BorderEffect' : is not a member of '_Chart' d: etrumform.cpp 1034 ". The code is as follows: _ChartPtr pChart; pChart->BorderEffect = BorderEffect_None; I check the definition of _ChartPtr as follows: typedef _com_ptr_t<_chart>_ChartPtr; I think that it is a com component here, can you tell me how should I solve this problem I appreciate your help. I'm a bit rusty at this COM business, so bear with me. The tlh file is a result of importing a type library and generating corresponding a header file that can be used against your C++ code.

Windows Forms Getting the DataRow that corresponds to the CurrentRow of a DataGridView
Below is my code for getting the DataRow that corresponds to the CurrentRow of a DataGridView. The cast to (DataRowView) below is safe In my application, but it strikes me as awkward, and the whole method feels unnecessarily complicated. It seems like there should be a simpler way to do this. Am I missing something somewhere === code follows ===== DataGridView _grid; public DataRow CurrentRow() { DataGridViewRow vr = _grid.CurrentRow; DataRowView rv = (DataRowView)vr.DataBoundItem; return rv.Row; } Nope - that sounds right. The old DataGrid control was essentially the same way. The DataTable is wrapped up in a DataView because DataTable does not offer sorting, filtering, etc. And for each DataRow i ...Show All
Visual Studio Team System How to Buld Web Applications in TFSBuild?
Hello, I have spent sometime trying to find a solution to this problem but have been very unsuccessful to date. Essentially I have changed from a Website Project to a Web App Project (I got this from VS 2005 service pack 1) which seems pretty straight forward and it builds on my local machine without a problem. However, when I try to build the solution using TFSBuild on our server I get the following error message: Solution: , Project: COENextGen.sln, Compilation errors and warnings D:\WebAppBuild\LatestBuild\COENextGen.Main\WebAppBuild\Sources\COENextGen\COENextGen.WebApp\COENextGen.WebApp.csproj(670,11): error MSB4019: The imported project "C:\Program Files\MSBuild\Microsoft\VisualStudio\v8.0\WebApplicati ...Show All
Visual Basic Conversion from vb.2003 to vb.2005
I recently converted a large (40+ class library projects + the exe) project from vb.2003 to vb.2005. The conversion went well with a few warning message mostly consisting of object used before value is set and using a shared method from a class instance instead of the class. I corrected these warning messages. The method used for the conversion: copied the path containing the vb2003 version to a new path and opening the solution file in vs2005. I did not save a backup since I was using a new path. The class library projects reference other class library projects. For example I have a class library project containing commonly used functions such as Crude Oil volume correction, ticket calculation, etc. Other class library project reference t ...Show All
Visual C# Is it safe to remove a delegate inside its delegated method?
This sounds a bit strange but it's a real world problem. Say I have an event Disposing and a method F() handles that event. obj.Disposing += new EventHandler(F); ... void F() { ... obj.Disposing -= new EventHandler(F); } Here's the problem, F() is going to remove itself from the invocation list of the Disposing event right at the time it's invoked. I don't find a statement for this in the spec. So could anybody tell whether this is designed to be safe or not guaranteed Thanks in advance. qrli wrote: I think I haven't made myself clear. sorry. The problem I'm thinking is like this: Say I have an event whose invocation list contains three functions {E(), F(), G()}. And the invocation o ...Show All
Visual Studio Team System Uninstall SP1 on data tier problem
I'm having many of the same issues that several others are having when trying to replace SP1 Beta with SP1 RTM on TFS. However, this particular problem is on the data tier, which I have not yet seen documented. When I run the uninstall for "Microsoft Visual Studio 2005 Team Foundation Server (databases) - ENU Service Pack 1", it moves along nicely, and then fails. The log file for the uninstall contains the following lines: MSI (c) (E4:BC) [09:12:08:874]: Product: Microsoft Visual Studio 2005 Team Foundation Server (databases) - ENU - Update 'Microsoft Visual Studio 2005 Team Foundation Server (databases) - ENU Service Pack 1 (KB922996)' could not be removed.

Visual Studio 2008 (Pre-release) Simulating no-textwrap in RichTextBox
Hi there, I read somewhere that the RichTextBox control doesn't have a property to turn TextWrapping on or off like TextBox, and that the only way to simulate TextWrapping turned off is to set the FlowDocument within the RichTextBox to a width that would accommodate the longest text line. Just wondering if there's an easy/elegant way to get the longest text line within the FlowDocument such that I can just bind that to the FlowDocument Width and thus simulate the no-textwrapping behavior. As background, I'm planning to use the RichTextBox as an Xml editor with syntax coloring, so I need the text content not to wrap. Thanks!!!

Visual Studio Express Editions read/write reg_binary
Hi, I'm hoping somebody may be able to help me out. I'm trying to read/write numbers larger than 255 into registry in reg_binary format (pairs of hex). As an example: I'm trying to write 315 and what I would like to see in registry is 3b 01 (little-endian architecture) but what I end up with is 33 00 31 00 35 00 basically each digit is converted in to byte.... I'm trying to write a plugin, so if I don't write it in the correct format, prog won't understand it... Any samples would be greatly appreciated. Thanks art If you just want to write a 'number' as a binary value, try something like this: Registry.LocalMachine.DeleteSubKey( "Software\Test" , False ) Dim regKey As RegistryKey = Regist ...Show All
Visual C# blocking 2 of the same exe's from runing
im building a client/server application and I only want to allow the user to run one client per computer, what are some ways to block that 2nd client from starting up on a comp that is already runing a client thanks One of the best ways to do this is for your application to define a mutex that identifies your application to other copies of itself. Below is the code I run for this task: System.Threading.Mutex singleInstance; private bool AmIAlreadyRunning() { singleInstance = new System.Threading.Mutex(false,"MyApplicationNameMutex"); return !singleInstance.WaitOne(1,true); } With this I simply call AmIAlreadyRunning() to find out the answer to that question, if true ...Show All

Visual C++ About this Forum
I read the heading of this forum, which says " General questions about Visual C++ 2005, including the development environment, libraries, setup, debugger , samples, and documentation." Seeing the word "debugger," I asked a couple questions about the VS2005 debugger, and they were both moved to a debugging forum. In which case, I wonder why the word "debugger" is part of the description of this forum. Anyway, the questions being moved wouldn't be so bad, except that nobody has answered my questions on the much lower traffic debugger forum.
