• .NET Development Partial Classes not good OO design

  Does Microsoft even bother involving developers anymore in their process of developing new "features" I've spent about four hours with VS2005 now and can't believe the list of problematic improvements I've generated in that short time. Then I run across this partial class feature. What a pitiful idea. This isn't an object oriented concept at all - it's very much akin to using a preprocessor to insert code. The ability to "hide" code is pretty much covered by the OO model - it's called encapsulation. Hiding UI code is the reason given for this "innovation". What happened to patterns such as MVC Even a U ...Show All

• SQL Server derived column transformation expression

  Hi. I am using the following expression to check if the first charcter of a string is not the letter "E" and if it is, strip it off by selecting the remainder of the string: SUBSTRING([Derv.comno],1,1) == "E" SUBSTRING([Derv.comno],2,10) : [Derv.comno] This is ok in 99.9% of cases, but ideally I would like to be able to check, and alter the string if the first charcter is anything but numeric I had something like this in mind: SUBSTRING([Derv.comno],1,1) != ("1","2","3") SUBSTRING([Derv.comno],2,10) : [Derv.comno]  but the syntax is incorrect. Could you tell me if wh ...Show All

• Windows Forms DataGridViewComboBox - different items each row

• Visual C# How do I move my records in one dataset into SQL database with field matching?

  I am working on a attendance application( base on SQL Express) for school, I figure out the way import the CSV files(Attendance Record) into a dataset but I cannt find any information regarding how to transfer the record into SQL Express Thanks Hi, Try using the sqlDataAdapter object. You need to set its select, insert, update, delete command. After doing that you can try doing something like: System.Data.SqlClient. SqlDataAdapter adapter = new System.Data.SqlClient. SqlDataAdapter (); //Set the commands.. adapter.Update(dataSet); The adapter will check the status of each row in the dataSet and will invoke the apropreat ...Show All

• Visual C++ stringstream causes memory link VC++ 2005?

  This simple program seems to leak LOTS of memory when compiled in VC++ 2005: int _tmain( int argc, _TCHAR* argv[]) { for ( int i = 0; i < 100000; ++i) { ::Sleep(1); std::basic_stringstream<TCHAR> str; str << _T( "Current iteration: " ) << i; } return 0; } CRT: Multi-threaded debug or Multi-threaded I compiled and ran the same piece of code in VC++ 2003 and I don't see ANY leaks!

• Visual Basic ComboBox loses Selected Index after Keypress

  Hi, I've ran into what I believe might be a bug with ComboBoxes. I found it trying to implement type-ahead functionality. It appears that when I set a selected index value in the text-changed event of a combo, I seem to lose that value after the event has been processed. I thought at first it was the recursive call back into TextChanged, but the value is still there at the end of the procedure. I'd appreciate some feedback before I submit it as a bug. One thing that I'd like for someone to try is to set a break when SelectedIndex = -1 is True. VB Express doesn't allow you do that so I can't see what internal event is causing it to cha ...Show All

• SQL Server "there is no 64-bit JET provider...."

  Yes, I admit it. I am leanring SSIS on an x64 bit machine (with Windows 2003 Pro x64, 9GB of RAM). I have installed sql 2005 Sp1 on the same machine. As I found out today, there is no 64-bit JET provider which explained why I couldn't use SSIS to import a simple Excel file. (I spent an hour fighting with SSIS before I gave up. Time required to setup the Excel import under sql 2000 DTS, 2 minutes.) What other 64-bit related surprises should I know about TIA, barkingdog   barkingdog wrote: As I found out today, there is no 64-bit JET provider which explained why I couldn't u ...Show All

• Visual Basic How do I save an already saved project to a different location?

  I must be missing something really simple... I downloaded a sample Project from the web.  I opened the sample Project in Visual Basic 2005 Express Beta 2.  After making a lot of modifications to the sample Project, I wanted to save my new project with its own different name, and in the usual directory where I have been creating other projects.  I pressed Save All and accepted the default choice.  Unfortunately, after pressing OK, I realized that I had saved over the original downloaded sample project, and had saved my modified project in a temp directory designed to receive downloads from the web. It's not ...Show All

• Visual C++ lnk1112

  In VS2005, I added a MFC DLL project. The default platform is win32 and this project does not have input lib. A very simple boiler plate project with code from Microsoft. Then I converted the project to x64 by setting the platform type to x64. I can see that the target machine type from the Linker option got changed to x64. Then I built the project from VS2005, I got the following error: \ x64\Debug\mfc2.obj : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64' Note that there is no input library and therefore there cannot be a mix of object modules.

• Visual Studio Team System B3R to RTM - eventually

  Does one have to install the various builds/CTPs between B3R and RTM to have upgrade support to RTM Hope not. We plan on going from B3R to RTM due to the resources and time required to perform previous upgrades. Upgrading from Beta3Refresh->RTM involves many steps that include backing up data, running utilities to update your installation and performing some manual steps to complete the process. For a reference of How to prepare to upgrade to RTM, Refer to http://blogs.msdn.com/team_foundation/archive/2005/11/15/493188.aspx For a reference to the major changes since Beta3 refresh, Refer to http://blogs.msd ...Show All
