• .NET Development PropertyGrid / CollectionEditor doesn`t call my Add- Methode

  Hello, I'll try do describe my problem: I'm developing an application to draw/export class diagrams using C#, .Net Framework 1.1. To let the user edit the properties of a class or relation, I'm using the PropertyGrid- Control. Since my class- objects are UserControls, they have many properties inherited I don't want to show in the PropertyGrid. For that reason I built wrapper- classes, which only own the properties I want to offer. Some of these properties, e.g. the operations or attributes of a class, are realized in the original UserControl- class as hashtable. To display these hashtables, I built own Collection classes (which extends the System.Collections.CollectionBase- class), so you can say that these are kind of wrapper classes for ...Show All

• SQL Server Matrix Report and Expression on field

  I have a matrix report that has two columns, and one of the colums has the following expression for background color: =IIF( Fields!Percentile.Value >= .10, "Yellow", "White") Basically if the percent is greater than 10 highlight the field, for some reason i have some fields that dont show up yellow, see below: http://duhaas.googlepages.com/percent.Jpg your colour expression needs to wrap the field reference with the same aggregate function as the textbox value expression. So, if you are using: =sum(Fields!Percentile.Value) as your value then change the colour expression to =IIF( SUM ( Fields!Percentile.Value ) >= .10, "Yellow", "White") this is because when no aggr ...Show All

• Visual Studio Team System Pre-build validation failes for setup project

  Hi there, I am trying to build a setup project (.vdproj) using team build. I am aware that msbuild does not support building setup projects and one has to add custom task to build setup projects separately using devenv. I have added a custom task in TFSBuild.proj file to build the setup project. However, it fails to build it and gives an error. The command I have added is: >D:\Program Files\Microsoft Visual Studio 8\Common7\IDE\devenv" $(SolutionRoot)\Setup\Setup.vdproj /Build "Release" The error it shows is something like this: ERROR: Invalid or unspecified target for shortcut <shortcutname>, ERROR: Cannot find outputs of project output group '(unable to determine name)'.

• SQL Server Package not picking up latest Config File changes

  Hi, I've created a solution with 5 packages in. I've scripted a config file for each package where I would be able to change the source file connection and the database servers (source and destination). On the first package, I am able to change the config attributes and the affects are picked up, but the rest of the packages do no pick up the changes. For example, if the source file is "C:\Files\source.txt" and this is changed to "C:\Files\source123.txt" (Just to make sure it fails) it wont pick up the new changes and still uses "C:\Files\source.txt". Also, I tried changing the name of config file itself and the package still ran as if nothing had changed. It's as if it's not recognising the config fi ...Show All

• Visual C++ missing .lib files for x86 in Platform SDK where do I get them?

  I have installed "Microsoft R Windows ServerR 2003 R2 Platform SDK Web Install" and Visual Studio 2005 Express Edition and my programming seemed to work fine (Visual C++) until I needed to include fstream.h witch includes iostream.h, but now I cant compile because of some missing .lib files wich I find in the \lib\AMD64\ folder and \lib\IA64\ but they dont work on an x86, then I read on the install page for the Platform SDK that x84 compiler is not included I guess that is the reason for my problem, but where do I find my .lib files for x86 then otherwise, can I work around this problem somehow, I need to read ASCII numbers data from a .txt file.

• Visual C++ Project organization

  I find myself against the wall. I am at a place where I have never gotten beyond because I do not understand the organization of projects. In the past I have done top-down programming. I've gotten fairly proficient with it, even though I have never gotten deep into the system with it. An example of the type of coding I am familiar with is here . While I can understand the concept of classes and objects, the organization of object-based projects throws me. As example, the app I'm writing. Using windows forms I created this project. It has 2 header files (Form1.h and stdafx.h) and 3 c++ files (AssemblyInfo.cpp, ProLite.cpp and stdafx.cpp). So far,all of the code generated by the designer is going into Form1.h. All of it. I know that I am ...Show All
