• Windows Forms CollectionEditor problem :(

  I've been working on a CollectionEditor, but I'm getting an obscure error message whenever I try to use the Add button. To reproduce and demonstrate this error, I've made this short piece of code: using System; using System.Collections.Generic; using System.Text; using System.Collections.ObjectModel; using System.ComponentModel.Design; using System.ComponentModel; using System.Drawing.Design; namespace Test { public abstract class BaseItem { private string _name; public string Name { get { return this._name; } set { this._name = value; } } } public class IntItem : BaseItem { private int _value; public int Value { get { return this._value; } set { this._v ...Show All

• Visual C# Move Directory Across Volumes

  I have developed an application designed to copy a directory on the D:\ drive to the C:\ drive, and I recieve a message that it can't copy across volumes using the following line of code: System.IO. Directory .Move( "D:\\WBWU" , "C:\\My Documents" ); Would that work, or am I wrong That's right. I guess one way would be to go through each file and sub folder and copy it that way. It's a bit hard but there is code to do this on these forums. It's to do with security permission apperently ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. New Starter kits?

  Hi everyone! I just joined the creators club and deployed my first game (The spacewar kit) and everything worked great!

Are more of these comming in future updates Or am I just missing them 1) Yes. 2) No. The XNA racer kit is not ready yet. See here . ...Show All

• Visual Studio Need RAM

  I have just excuted some data flow packages, which requires more RAM, virtual memory. I will continue building the DW etc etc... Today I have altogether 256kb + 256 kB. What if I change one to 512kb. Would that be enough or should I by 1 GB How much RAM you need depends on several factors. 512MB is a minimum and I have experienced that 2GB of RAM is ideal. Nevertheless the increased productivity that you gain by adding extra RAM by far outweighs the cost. But for now, try to increase the paging file to the recommended settings and shutdown services and applications that you are not using (Eg SQL Server Developer Edition) ...Show All

• SQL Server PDF Rendering bug

  We are trying to publish a group of financial reports using SQL Server Reporting Services. We have hit a snag when we try to render the reports in PDF format. The leading spaces of each line are stripped in the output file. For example: Department 10.7240 - ICU Expenses SubDepartment -------- ------------- 1,200 100 454 150 Becomes: Department 10.7240 - ICU Expenses SubDepartment -------- ------------- 1,200 100 454 150 Does anyone know a solution for this problem By the way, we did upgrade to SP2. That did not correct the problem. Thanks for the information. Actually we are moving a fully formatted report from an old DEC Alpha system to .pdf ...Show All

• Visual C++ Static Datatype

  Hello I am not sure when to use a static data type when coding a win32 program. Can someone pls explain that concept. Thanks Revant wrote: Can someone pls explain that concept. Static has different meaning, depending on the context. If used in a function, the variable will retain its value for all executions of that function. It will be initialized only once. void foo() { static int myVar = 0; myVar++; // myVar will be incremented by one, for each execution of foo() } A class function marked static will be callable without an instance of the class class Foo { public: static void myFunction() { // myFunction can not access non-static members of Foo! } }; ...Show All

• Visual Studio Team System Performance Analysis in debug mode

  Hi, i have a solution with 7 projects, one .exe project and 6 .dll projects. I want to profile info on one of the .dll project. I can do it in "release mode". My question: Is it possible to collect profiling (instrumentation) info in "debug mode" If possible, how can i do it When i try to do it, i receive the error message: "Assembly was not found. Please check your Application installation" Thanks. Abongs Abongs, Yes you can collect profiling data in debug mode, although I would not advise it. In debug mode, your code will not be optimized, so you may end up spending time on areas that are not really performance issues when running in release mode. However, if you really want to you can debug in profi ...Show All

• Visual Studio Team System Merging: How is the target branch determined (or: how to merge)

  Hi, I am trying to merge a changeset into another branch. I'd like to know how Team Foundation Source Control determines what target branches are possible to choose. Let me explain by examplifying. My branch setup is this The root is branched into 2 separate branches, A and B A is later branched once more, so we have A and A.a. Now, I'd like to merge a changeset from the branch A.a directly into B without merging the change into branch A. Is this possible The target branches I get when I choose the A.a source tree is only A, not B. For the simple case this is true but I am going to write a blog post that shows how this fails for a lot of the complex scenarios and why we decided not to do it. Now that does ...Show All

• Visual C# Prebuilt collection class?

  Does .NET 2.0 have any pre-built (non-abstract) collection or dictionary classes I'd like to have a simple collection with strings as indices and some custom objects as values, where I can add, remove, check if an item exists, and get an item by index. I really don't want to have to implement all of the needed methods, but I haven't been able to find any ready-made collection classes in the .NET libraries. Any ideas To answer my own question, I found it: System.System.Collections.Generic.Dictionary<key type, value type> The implementation is a little unwieldy (separate ContainsKey() and ContainsValue() methods, for example), but it will have to do. ...Show All

• Visual C++ Change DLL Search Order Dynamically?

  Is there a way I can alter the dll search order dynamically (launching executable process) * SetDllDirectory( ) only works with LoadLibrary/LoadLibraryEx * CreateProcess( ) doesn't seem to have any flags/parameters to toy with. * LoadLibrary( )/LoadLibraryEx( ) don't load executable bits for executing (only for resource manipulation) * Changing values in the registry upon load is unacceptable and would likely break anyway. einaros wrote: Rafael Rivera wrote: Yea, I went down the Detours path but couldn't find a way to avoid having to write a copy of the original executable to disk so I abandoned it.
