• Visual C++ Asked for VC 7.1 libraries when compiling a project in VC 8

  Hi folks: I encountered a problem when I was compiling a VC++ 8 project convered from .NET 2003 in Visual Studio 2005. When the process came down to link stage, the VS 2005 IDE asked for some version 7 VS libraries such as "mfc71.lib", "mfcs71.lib", "libc.lib", etc, which are not included in VS 2005. Could anybody provide any hints for cracking this problem. Thanks a lot in advance.

• Visual C# library not registered error

  Hello, I hope someone will have an answer to this question... Using VS. Net + C# I have a a console project called implementer that communicates with another addin project. Both are supposed to send and receive a "struct" that holds a hashtable to store/change info. I got the addin to show up right and it starts listening to the events been triggered by excel. In one of the events, the addin class, via invocation, is supposed to instantiate an instance of the struct and pass it to the running instance of the implementer class which changes and modifies the info in the hashtable of that struct. when trying to send that struct (which is a dll file by itself but added to both projects as reference) I get the error message s ...Show All

• Visual Studio VSS 2005 install not installing VS 2005 plugin.

  Hello, Not sure what's going on but has anybody successfully been able to get the VSS 2005 install to complete successfully and when finished, have the VSS plug-in available in Visual Studio 2005 I have enabled the IIS compatiblity. I right click and run the vss setup as administrator. I get no error messages but afterwards, if I click on file there is no source safe option. Also, when I try to open a website, source safe isn't an option. My database server is on a remote W2k3 server. I need the add-in for Visual Studio to open projects from databases on remote servers. Also, I have tried installing VS 2005 SP 1 beta. (Not that I could see how it would make a difference but tried none the less.) Any ideas of how to get this ...Show All

• Visual Studio Express Editions How do I know if the text in a text file has changed? How do I program Save and Save As?

  I am trying to create a notepad-like program. I noticed that on Notepad, when I go to File | New, Open, or Exit, the program displays a message box saying that the text has changed. I was wondering how I make the program recognize the text has changed and put it into a MsgBox Another problem... I know how to program Save As, but how do I program Save Finally, Notepad is able to display in the title bar just the filename, and I was wondering how to do that. For example, I want it to say "Sample - Notepad", not "C:\Documents and Settings\Administrator\Desktop\Sample.txt". Any suggestions Thanks a lot. Declare a public boolean outside of a sub.

• Visual Studio Express Editions Save Solution As...

  Hi, I've noticed something with Visual C# 2005 Express and wondered if it was normal or if I was doing the process incorrectly. I'm copying a Solution [using File Explorer] and giving it a new name. Then copying'n'pasting that name over the solution & project inside the solution explorer, after opening the new solution. This seems to deal with all files and paths except one, the Project Directory doesn't get changed. The project & solutions all work, however, if I try and change the project folder manually [using File Explorer again] then they stop working. Is there a way to have all the paths renamed successfully by the Visual C# 2005 Express application tia, This doesn't appear t ...Show All

• .NET Development A Read-only dataset

  I have a singleton class which contain a DataSet. And also provide a property which return the dataset. How can i return a readonly dataset so that the object that is asking for it wont modify the data and the structure of the dataset Thanks, I do not know your design but solution could be if you make ALL your controls that manipulate data just to display it. Another approach is to make property that return dataset internal. in this way you ensure that only assembly callers could use it hope this helps ...Show All

• Visual Basic Enum members 'not declared'

  I am converting a VB6 class module to VB.NET. There are some enumerations whose members are referenced in the code. The editor says those members are not declared.

• Visual Basic Error occuring for one user only after upgrading to Visual Studio 2005

  Here is my question: I have a Visual Basic Windows Forms application that was developed in Visual Studio.NET 2003 and was recently upgraded to Visual Studio 2005. After reinstalling the application one of my users is getting an error, but the strange thing is that this is happening to one user only, out of about 25. So basically, the application works fine for everybody except this one user. The error was not occurring before we upgraded to Visual Studio 2005. I have installed and reinstalled .NET Framework 2.0 on his machine a couple of times, same thing with the application, but the error is still occurring. I doubt it's something in my code because otherwise it would be happening to everybody else. I have tried unsucc ...Show All

• Windows Forms Properties window keeps giving me "Object reference not set to an instance of an object." error

  Howdy folks, When attempting to change some of the properties in the Properties window for some components within the main form of my windows application (e.g. the DataSource property within a DataGridView, the DataSource for a BindingSource, etc.), the following error message pops up in a message box without any further information:    "Object reference not set to an instance of an object." All the properties which are giving me trouble seem be data-related. Unfortunately, I'm not able to augur what this is supposed to mean, and what I should do to remedy the situation.  Anyone have any recommendations FWIW, I was doing some code restructuring between projects when this occurred, so maybe something ...Show All

• Visual Studio 2008 (Pre-release) Smart & Lazy Scrollable List ;-)

  Hello, I'm using a gridview/listview in order to display a grid of data to the user. However the potential # of rows can be very very large. So: 1. I don't want to get the entire list. 2. If I can, I would like to avoid (first, prev, next, last) paging scheme. So I was thinking maybe I could break the list into pages and employ lazy loading. In other words, have a slot of pages (lets say 5 pages), and as the user scrolls, I move the slot of pages and proactively gather rows from the db, keeping a few steps ahead of the user. I realize that the user may scroll faster than the lazy-loader or may just jump to the end of the list (I'm not sure how to solve those problems yet: one step at a time I guess). I got 2 of questio ...Show All

• Windows Forms ListView Column Widths Question

  Hi folks, I'd like to retrieve the current width of a column in a ListView, except I'm having troubles figuring out how to get the column I want to work with. My WinForm is using C/C++ - advice -Zero I could reproduce your error message using the VS2003 compiler. Fix it like this: int w = listView1->Columns->Item[ix]->Width; Writing code in Managed C++ is a dead end, run to the store and buy VS2005! The C++/CLI syntax is much improved... ...Show All

• SQL Server Problems with the SELECT ROW_NUMBER() OVER approach
