• Windows Forms Tough Reflection Question

  If given a FieldInfo object that represents a reference type, is it possible to call a method on this reference type  I know how to set and get the field, but that's not what I want to do. I want to actually call a method on the field.  For example, let's say that I wrote a function that uses reflection to get a list of every&n ...Show All

• SQL Server System.Data from NETCF and System.Data from .NET

  Currently, I have a WinCE application which uses the System.Data from NetCF and System.Data.SqlserverCE from MSSQL Server 2005 Mobile Edition. Now, I'm trying to use the System.Data.Sqlclient but I can't seem to find it in my System.Data. I notice that there are different version which is one from NetCF and one from the MS.Net framework itself. Here's my question: Is it possible for me to use both System.Data or should I only choose one. This is for my attempt to connect also from an SQLServer and connect to the local SQLServerCE as well. Thanks in advance, rikimaruXP yes, the SqlClient that allows a CF app to work directly with SQL S ...Show All

• Visual Studio Team System SourceContext.Documnt is null

  Hi, I've problem with my rule. I can't receive node.SourceContext.Document. It's always is null. That why I can't receive location of this node in source code. Pdb file is located in the same folder that assembly. My rule based on BaseIntrospectionRule. Interesting feature: if I run my rule with rule, based on BaseControlFlowRule, all is correct. node.SourceContext.Document is not null. Please help me with my problem. Thank you.   Not all nodes in the tree have SourceContext. You need to remember the source context for the last node in the tree that you encountered that had one (gen ...Show All

• Windows Forms Create custom UI type editor for control property ?

  Hi, In my custom control, I have a property of a type IRenderer , which is a custom interface in my project. During design time, for that property, I want the PropertyGrid to display a list of all IRenderer -derived controls/components on the current form. How can I do that I suspect I have to create a custom UITypeEditor but I have no clue. Perhaps I need some reference documents or articles. Thanks in advance. You don't need to create a custom UITypeEditor for this. The standard UITypeEditor should list the controls/components if you have place the pieces together. public class Class1:Control, IRe ...Show All

• .NET Development Converting between Ver 1.1 and ver 2.0 .net

  Howdy, I have just written a small program in VB 2005 in .net framework 2.0, i wondering if there is a way that the executable could still run in ver 1.1 as i have been getting errors (ie not compatible!)    The program is very simple, and i dont think i use any new "fancy" parts of 2.0 (I am very new to VB and .net....like today) thanks... Dwayne Ok, I tried a small experiment and Yes, you are correct. I got a "Application generated an Exception that cannot be handled" when I tried to force a v2.0 EXE on v1.1 So, I guess the only option is to rebuild the app for v1.1. Regards, Vikram ...Show All

• Visual Studio How to speed up help integration into Visual Studio help collection using merged modules?

  Hello everyone,   I am developing an installation of a .NET component for Visual Studio 2003/2005. I have created a HxS documentation for the component and included the necessary merged modules to my installation. Everything is working fine and help is integrated into the Visual Studio environment. But the installation takes very long time. I think the problem is that the Index and TOC files of the Visual Studio help collection and my help collection are merged during the installation. But I would prefer the Index and TOC files to be merged after the installation, when the Visual Studio help collection is first accessed. What c ...Show All

• Windows Forms getting active form for application

  I want my messageboxes to center over the active window, not the centerscreen. I see the owner parameter and this works when I pass a form. Sometimes, I want to display a messagebox from a class though and have no reference to the calling form. I thought I could use Form.ActiveForm, but it always seems to return null. How would I go about this Thanks There’s good news and bad news. The good news is that the .NET Framework’s MessageBox class internally uses the GetActiveWindow API function to retrieve the handle of the active window attached to the calling thread, so assuming you’re trying to disp ...Show All

• Visual FoxPro Index on Deleted() VS .NOT. Deleted()

  Which is best for performance index on deleted() tag del or index on not deleted() tag notdel Thanks Hi If you're using VFP8 or earlier you have to use the former. From VFP8 help: "Rushmore cannot use an index created with a NOT condition . For example, the following expression can be optimized: INDEX ON DELETED() TAG DEL But this one cannot: INDEX ON NOT DELETED() TAG NOTDEL" If you're using VFP9 " INDEX ON NOT( DELETED ()) optimizes NOT( DELETED ()) and DELETED () query conditions" and you can use a Binary index - see h ...Show All
