• Visual C++ Unresolved external using a namespace from a DLL

  Hi, Under Visual Studio 2003, I have a DLL that exports a class, and I am trying to use the class from the DLL in a simple test application. The class in the DLL is defined inside a namespace. The problem is that the test application builds fine in debug mode, but I get a link error in release mode: Maybe the DLLDIR_EX symbol is not defined in Release configuration of DLL project ...Show All

• .NET Development metaclass/class references

  Hi, I'm in the process of learning c#, but i'm getting the hang of it pretty fast. The problem is documentation. I've read up on C# reflection, and i'm already using it, but there are certain things which aren't stated. For instance, my issue is that of class references. How do you do such in C#. Like for instance, delphi: <code> {* class reference declaration *} TDBObjectClass = class of TDBObject; {* Method returns the remotable object for a given class type...the method here is a class funciton *} TDBObject.GetRemotableClass(aClass: TDBObjectClass):TRemotable; begin ..... end; </code> What is most IMPORTANT about my question is the fact that I am not concerned with the Dynamic creation of the class us ...Show All

• Visual Studio 2008 (Pre-release) Read value of a Binding manually

  Given a Binding object, how can I read the source value I.e, I'm bound to a Customer object as my source, and the path is "CustomerName".

• Visual Studio Team System "Need to know" model in MSF Essentials book

  I'm sorry, this is not really a MSF related question. I'm reading Michael Turner's MSF Essentials. In Chapter 3, page 22, it says: "....Worse yet, some still perceive information and knowledge sa power and share as little as possible. This "need to know" model of restrictive communications is very counterproductive....." Anyone can tell me what is "need to know" model and why call it "need to know" Thanks!!

• Visual C++ Useless "Failing" Failure Dialog.

  I'm having an issue with binaries created with Visual Studio 2005. I'm compiling using /CLR:oldsyntax. It seems as though every time I am hitting an unhandled exception (I don't think it matters if it's in managed code or not) and there is no debugging environment available (ie: on a machine without visual studio installed, or running with the Debug menu item "Start without Debugging" I get an absolutely useless dialog, with the caption "Failing" and the only text in it is "Failure." and an "OK" button on it. Obviously this doesn't help the whole debugging process whatsoever. What has happened VS 2003 builds always showed more information! Does anybody else get this Am I doing something wro ...Show All

• Windows Forms Creating my own TabPage class

  I have a tabcontrol on a form. If I add tab pages and add controls to them in Visual Studio the controls become members of the main form and the main form will also handle all events from all controls on all tab pages. I want to create my own TabPage class that handles everything that happens in the TabPage to avoid having all code in the main form. I created MyTabPage class by adding a new Component to the project and changing the base class to TabPage. I am able to drag stuff from the Toolbox onto my TabPage in Design mode. In the designer for the main form I added another tab page to the tab control and changed the type from TabPage to MyTabpage in the main form code. However, I am not able to see any controls in the tab when I ...Show All

• SQL Server Longarse txt Source files

  I thought i share this lil thought/tip with ya'all: I have .txt import files which have huge amounts of columns (this time about 150 - 200). And i need to import 3 of those files. I do have the definitions for columns - but to fill out 200 column definitions in SSIS editor takes u a while. (And suggest types is quite useless due to 1000 sample row limitation - not to mention that if you identify Boolean fields using Y,N - i throws errors on import - so you are most of the times better off defining your own columns). Fortunately for me - majority of the fields is similar (over 100 fields) - so I can copy and paste the flat file connection and make changes to copied file connection I guess my wish for future version is that flat file manage ...Show All

• Visual Studio Team System How to delete ChangeSet

  My colleague checked in a set of incorrect source code. I want to remove this ChangeSet. How can i do As Luis correctly says - changesets can not be deleted. The server maintains a history of the changes commited to a file and being able to delete points in the history would invalidate the audit trail on a file. Instead, you can check out the files and then undo the changes by copying in the older versions from the history of the file. An alternative is to use the "tfpt rollback" command. tfpt is the command line power toy which is available here:- http://go.microsoft.com/ linkid=5431080 Hope that helps, Martin. ...Show All
