VS 2005 : Generating A Folder Tree Using Regression?
Apr 1, 2010This problem has been doing my head in all day and wouldn't mind a bit of advice. Basically I have a table in my db called tblTree which looks a bit like this :
TreeId, ParentId
1 0
2 0
3 2
Each row represent a folder.The TreeId is a unique Primary Key.The ParentId refers to the folder this belongs in so in the above example TreeId 3 is a folder created in the the folder represented by TreeId 2.The 0 in ParentId represents the root.How in Gods name am i supposed to create a folder structure using this table?
Translate A Call Of The LINQ Extension Method Select Into A Corresponding Expression Tree?
May 23, 2012The following LINQ query resp. call of the extension method Select in Visual Basic 2010 is working fine:
Dim qAvSalary = qJobData.Select(Function(e) e.AvSalary) But doing so I am not able to specify the name of property I want the query (e.g. AvSalary) using a string variable. This should be possible if I use a LINQ expression tree. Searching and trying a long time on how to translate the query to a corresponding expression tree was not successful. My final approach is:

Tree.SelectedNode = Tree.Nodes(0) 'returns Error With System Reserved Partition?
Jun 12, 2011I am not the original author of this software project and the code is poorly documented. I am mainly a Java/C++ developer.The program displays the tree structure and allows files and folder to be selected. The program is getting errors with FileSystemTreeView when trying to return nodes on a system with a reserved partition.Here is what is happening: tree.SelectedNode = tree.Nodes(0) 'returns error with system reserved partition.calling, GetDriveList() will properly return all the drive letters - and not throw an error. Only when trying to get a tree.Node() or tree.load() is the error occurring.

.NET Native GUID Conversion
Nov 9, 2011I have an external database that is feeding information to me. One saves their data as native GUID format and my other data source supplies standard .NET GUID format string. Is there a tidy way to convert from Native GUID to GUID Structure? Also is there any validation bit to determine if a provided value is a Native GUID or not? I can't seem to find any if there is one. The difference is as follows:
typedef struct _GUID
{
DWORD Data1;
WORD Data2;
WORD Data3;
BYTE Data4[8];
} GUID;
Data1, Data2 and Data3 get their byte order reversed but Data4 remains the same, see [url] for more info.
Calling VB6 Native Dll From .net Project?
Jan 12, 2012I have a vb6 project in which I use a dll library to do some tasks. For that, I add a module which declares all functions of that library such as:Declare Function myFunction Lib "abcdapi.dll" (ByVal hVar1 As Long, ByVal hVar2 As Long) As Long When I call this function (and many other similar) I'm able to do the work and correct Long pointer is returned. But when I try to do the same thing by VB.net (by importing the same library using dllimport and calling the same function), I get no result. although it does return some pointer but that doesn't produce correct result.

Convert A .NET Service To Native?
Aug 20, 2009I need to convert a windows service written in .NET into native code, independent of the .NET framework. I've looked into using NGen to do this, but couldn't figure out how to use it. Essentially, I would like to take my windows service, run it through *insert app here* and have it bundle together all of the dependent dlls from the framework into their native code equivalents, so the service is installable without the framework.

DotNET Native Can Use Instead Of One Of These COM Libraries?
Nov 1, 2010I'm looking at a small remoting project in VB.NET. Initial research turns up references to msrdp.ocx which my Windows 7 Ult system doesn't have; a filesystem search on the same platform turns up MsRdpWebAccess.dll which doesn't appear to be well documented; finally hunting through COM references in Visual Studio turns up rdpencom.dll labeled "rdpcomapi 1.0 Type Library" which seems to be best documented via personal developer blogs (which isn't encouraging but is a lot better than other options).
My goal is a lightweight remoting application I can deploy to Windows 2000 Client/Server, WinXP x86/x64, Win2k3 Server, Vista x86/64, and Win2k8 Server.Is there anything DotNET Native I can use instead of one of these COM libraries? Is one of these COM libraries better for the job overall than others; and then am I going to have platform-specific compatibility issues if I don't provide support for more than 1 of them in my app?

Setting The Attributes For Native Structures?
Sep 5, 2010In a previous post [URL].. I needed to change how the values of an object's properties were displayed. In my case, I wanted to change how the native System.Drawing.PointF structure was displayed. If you check the post, it was resolved by using a TypeConverter.Now, my next question is how do I give existing properties attributes? For example, the System.Drawing.PointF structure has three properties: X, Y, and IsEmpty. I would like to give the X and Y properties descriptions. Also, I would like to hide the IsEmpty property, i.e., Browsable(False).

.Net Application Working Faster With Mono Then Under Native .Net
Mar 21, 2011To do some testing with MPIR, GMP, the .Net Bigint module and other math libraries I've recently written a small program which allows me to create random sequences of numbers with a certain amount of precision: Always this amount of digits in front and behind the comma, no starting/ending zeroes. While it might not be the most elegant of code, it really blew my mind when I found out my application was running up to 10 times faster with Mono under Ubuntu 10.10.While the code is not elegant and in Basic, it was developed by me in about an hour's work and it serves the purpose: To generate dependable huge datasets consisting solely of preconfigured numbers before or after the comma. To get a general idea the UI's posted here:[code]Eliminating IO by not writing to IO but just to a List instead Eliminating an "if" path which checks if the random before/after float character is checked.Disabled progress reporting in general which causes the backgroundworker to not report any progress.Play around with the amount of symbols, theres very little difference between just getting 1 random character or getting 15 per record.I'm at a loss to what causes my program to run so slow under Windows/.Net compared to Ubuntu/Mono. I'm only a "half programmer", which means: I'm a Bussiness and ICT student who mainly focusses on human ICT, and the Microsoft Platforms certainly have lead on that, however such a huge performance hit compared to Linux for this soul and simple program really gives me a cold chill when it comes to my favourite platform.
View 3 RepliesC - ExecutionEngineException Thrown When Calling Native Code
Oct 17, 2010I have a function that is exported by a C library with the following signature:
extern "C" BOOL Func()
The function is declared in VB.NET code like this:
<DllImport("mylib.dll", CallingConvention:=CallingConvention.Cdecl)>
Private Shared Function Func() As Boolean
End Function
The problem is that I get an ExecutionEngineException when I call the function from .NET code.
Given that BOOL is typedef'd as int in this C code, should the declaration be different? If so, how should I be declaring this? As Short or Int32? Do I need to marshal the return value?
C# Implement Late Binding For Native Code
Aug 14, 2009We are working with an existing native application (most likely written in VB) that loads assemblies and calls methods with "Late Binding." We do NOT have access to its source code. We want to implement this interface in C#, and have the native application call our C# assembly. Is this anything we have to do beyond matching the method names and method signatures to make it work?

View 2 RepliesMark Native Methods As Deprecated / Obsolete?
Aug 22, 2011In .NET you can mark certain methods as obsolete so that developers are alerted when they attempt to use the deprecated method.
<Obsolete("Do not call this method.")> Private Sub FormerMethod()
The thing is you can only do this within classes you control. What do you do when you want your developers to avoid using certain methods on classes provided natively in .NET or by a vendor?
For example, what if you want your developer to prefer some custom extension method on DataTable rather than Select. I'd hate to have to define a custom version of the DataTable class if only to deprecate Select. That would leave us having to police whether or not the custom table was being used.

View 6 RepliesReplace The Native ContextMenuStrip Of An AXWebBrowser With One Of Own Design?
Aug 15, 2009I'm am amateur but avid computer programmer. I have been trying to find the best ways and methods to design my own webbrowsing program, like so many others individuals, using Visual Basic 2008.
A few things are a mystery to me, such as how to replace the native contextmenustrip (cms) of a Microsoft WebBrowser (imported AXWebBrowser, not to be confused with the standard WebBrowser control in VB) with the contextmenustrip of my own design.
I've searched Google, MSDN, and other potential knowledge bases to no avail.
Allow me to repeat, I am not using the VB-standard "webbrowser" control that comes pre-loaded in VB. What I am using on my Form is an "AXWebBrowser" control, a reference to the Microsoft WebBrowser that I have added myself. It has much better functionality, as far as I am concerned.
how to replace the contextmenustrip for the AXWebBrowser?
Use NGen To Generate Native Images Of Their Assemblies?
Oct 20, 2009Does anyone use NGen to generate native images of their assemblies? I have always been quite puzzled by NGen because all MS articles that describe it basically make it sound like it has quite a few advantages compared to the disadvantages. Basically it looks like it will improve the speed of your application in most cases but if that is the case then why doesnt everyone use it all the time?or maybe they do and its just me that has not really used it much.The Native Image Generator (Ngen.exe) is a tool that improves the performance of managed applications. Ngen.exe creates native images, which are files containing compiled processor-specific machine code, and installs them into the native image cache on the local computer. The runtime can use native images from the cache instead using the just-in-time (JIT) compiler to compile the original assembly.
