• .NET Development Binding XML to datagrid and only showing and editing subelements in C#

  Hi our application has some xmlfiles I'm making a small frontend for in C#, in this we have a structure simular to <config> <Product> <InfoText>...</InfoText> <InfoText>...</InfoText> </Product> </config> What I want is to bind that XML to a datagridview and only show the InfoText Elements and let those be editable and make it so that saving propagates it back to the XML File. I'm having a really hard time wrapping my head around how to do this, especially using Xpath and datasets to build the link inbetween. I was hoping someone could help me out, hopefully with an example! Thanks in advance Please use XmlDataDocument. And Set DataMember of DataG ...Show All

• Software Development for Windows Vista XAML Based WF Linked to Assembly

  I am trying to set up an XAML based workflow where all of the activities are either common activites or defined in a custom assembly. I am loading the xoml file at runtime using an XMLReader to load the xoml file, then calling CreateWorkflow with the XMLReader. After working with this a bit I was finally able to get the workflow to load correctly. The workflow starts with a While Activity. The While activity calls a member of my custom SequentialWorkflowActivity class named 'ContinueLooping'. 'ContinueLooping' sets args.Result = true; This should result in a continuous loop, however, the workflow always completes right away. If I put a message box in the 'ContinueLooping', I never see the message box. If I change the name of the 'ContinueL ...Show All

• Visual C# remove element from an array of string

  hi everybody, I have an array of string myArray[0] = "Hello World"; myArray[1] = "This is a sample code"; myArray[2] = "Delete me"; how do I delete element 2 or I need to copy everything but element 2 I don't know what would be best in this case and if I have a lot of informations. thanks hi., I agreed with ShellShock. I develop like that because it is array of string (not ArrayList). If it is ArrayList, there is not much problem. You can do like this.: ( I assume it is ArrayList) myArrayList.RemoveAt ( myArrayList.IndexOf ( yourSearchString ) ); And you can also convert ArrayList to Array of string. For example: string[ ] copyStr = ...Show All

• Visual C++ Builds with IDE, but with msbuild LNK1104: can't find libc.lib??

  I'm converting a VC6.0 console application to use 2005. I have one project that will build fine using the IDE, but when I use the command line: msbuild MyProject.vcproj /p:Configuration=Release ... I get a fatal link error LNK1104: cannot open file 'LIBC.lib' I'm new to Visual Studio and Windows applications in general. I did some searching and found the link error is likely caused because libc.lib doesn't exist past VS6.0, and this project is trying to link with a binary that was compiled with VS6.0. I'm not sure what exactly that means, but okay, sure. Per the suggestions of other posts, I made sure compiler switches /MD{d} are being used (the old workspace used /ML{d} ), then I tried telling the Linker Input to ignore libc.c. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. I want to use a simple fx shader on a simple loaded model

  What I want to do seems very simple to me. I want to do this - Load a 3D model using ContentManager.Load<Model>(...) Load a shader Effect from a .fx file using ContentManager.Load<Effect>(...) Render the 3D model using the shader from .fx file. Can anyone give an example of this that is as straigh forward as humanly possible It does not seem like this should be a difficult thing to do, but I have no idea since I've never used shaders. Also, if anyone has a simple .fx file I can use to test my code, that would be great! I'd love to give my Buttermilk game / GUI engine the power of shaders! Thank you for reading! Very very useful :) One thing I don't understand clearly are the Effect.P ...Show All

• SQL Server Any clues why DTExec.exe is slower than Business Intelligence studio(SSIS Shell)?

  All, I have a simple package in SSIS that reads approx 2.5million rows from SQL2k5 source and exports it into 4 Foxpro files. The way I do it is as below 1) use and oledb source to read data from SQL2k5 2) use a conditional split component to divide the source into 4 streams ( I do a recId % 4 = 0, 1, 2, 3 to give 4 streams) 3) use an OLEDB destination to export to the 4 prexisting foxpro tables. This thing runs amazingly fast when I run(F5) it from Business Inteligence studio, but it is atleast 10 times slower when rightclick the package and execute using dtexec.exe I can't figure out why! any clues I would elimiate the 64 bit /32 bit problems because export to foxpro only works in 32 bit mode and my package has been configur ...Show All
