I have a file called CalcProg.DLL written in Delphi which is used in Plaxis. I am planning to write a VB.net wrapper for this DLL. The problem is that I don't know what function names there are in the DLL. I was wondering if there was a wrapper generator so I could input a DLL and the generator generates a dummy CalcProg.vb with the function names so I could have a VB class that does something like this:

I am trying to speed up the development phase by using codesmith for generating the business class DAL and info class for the tables of my project. There are about 50 tables with relationships parent child many to many and for retrieving data I have to code several inner joins in stored procedures. I have to combine fields from many tables and this makes working with the info class difficult. Is there anyway to generate info class from stored procedures or to be more exact is there a way to parse the result set of the stored procedure and to generate the info class with properties for every column in that result set.
View 3 RepliesDoes 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.

View 1 RepliesI'm creating a VB.Net Windows Form Application. Apologies if this is not clear as I'm still new to .Net. This consists of a text box and a gridview.The user is able to write SQL code in the textbox, click run and see the results in the gridview.It uses a SQL DataAdapter and the fill method to a datatable to populate the gridview.My problem is that I need to know the SQL datatypes for each column in the data table (NOT the .net ones). I.E SQL Server 2008 data type 'Date' is stored as System.Datetime in the datatable. I need to know if the SQL Server datatype is 'Date' or 'Datetime'.

View 1 RepliesI'm trying to add a control on my form and each time an error pops up : "Failed to import the ActiveX control. Please ensure it is properly registered". I'm currently upgrading from VB6 to VB.NET (VB2010 running on Win 7).I installed vb6 on my win 7 PC and i can still add that control on any form - so definitely the OCX is properly registered. My guess here is that VB.NET is unable to create a COM wrapper for that OCX.

View 2 RepliesI would like to create a .exe wrapper for a Flash Player using VB.NET. I am having a few problems.1.I seem to remember being able to import Flash Player as a control into Visual Studio (2008 Pro). For some reason, I can't seem to VS to import it anymore. (I tried using the OCX from Visual Studio) Perhaps I'm looking for the wrong file. What file am I looking for?
2.Is including Flash inside of a VB program legal?
3.When a control is included in a VB.NET program (such as Flash) does the control need to be distributed in a separate file, or will the compiled application contain it in the ".exe"?
I was able to import the control as the Flash10b.ocx from c:WindowsSystem32Macromed directory as a COM component. Question 2 and 3 still remain.Is there documentation on the ActiveX control? I am trying top figure out the API for ExternalInterface.

View 3 RepliesI have created a customized list (by implementing IList) where I added a few special methods. Sometimes (but not always), I only want to expose this list as read-only. To do this for normal lists, I use the Collections.ObjectModel.ReadOnlyCollection wrapper, which works fine typically. But it seems by passing my customized list through this wrapper, my added methods are no longer visible, which defeats the whole purpose of having this customized list object in the first place. How can I create a read-only version of a customized list?
View 2 Repliesbuilding a ASP.NET profile wrapper to use with an ObjectDataSource control. I would like to have the serialized profile data that I have defined in web.config be accessible via a FormView control within a user control. I'd like the users to be able to view and update their profile data. I have part of the code but am lacking the experience to complete it. I'm using a aspx page with some text boxes and having users update via a simple form now but I need something more reusable and efficient, not to mention moving the logic to a middle tier. I see that the ObjectDataSource control has some intrinsic ability to view profile common data but that seems to be limited.

View 4 RepliesThis is annoying. I'm trying to put a wrapper around some functionality that uses a web service to return some information. The intention is to wrap all of that communication into a dll such that the user can simply call functions from the dll to get back information, without needing to care about the service.As far as I can tell, that isn't possible, because the service information, as far as bindings and endpoints, HAS to exist in the app.config of the program that references the dll. That means that anybody using this dll won't just be able to add a reference to it and use it, like they would with any other kind of dll, they must also edit their app.config to add in a bunch of information. That's a simple copy and paste job, but it's incredibly unfriendly, and exposes some of the internal workings of the dll to casual inspection.
View 8 RepliesWe are converting a large VB6 application to VB.net. The problem we have all over the code is the .NET converter did not "reorder" the "IF" and other statements in the code to stop execution when a DBNull value exists. For example, we have code like this all over the place.
"If rRow.Item("av_election_id") > 0 And (rRow.Item("Challenged") <> "SUSPD" Or IsDBNull(rRow.Item("Challenged"))) Then"
This causes a error when "rRow.Item("Challenged") is dbnull
The line of code below corrects this issue but we have thousands of lines of code to reorder and refactor.
If
dtAVVoterRow.Rows(0)("av_election_id") > 0
And (IsDBNull(dtAVVoterRow.Rows(0)("Challenged"))
OrElse dtAVVoterRow.Rows(0)("Challenged")
<> "SUSPD")
Then
creating a wrapper class or something to allow us to keep the first example of code above where it will not throw an error when encountering a Null value? I don't know if a wrapper that reordered the If statements, or captures the error but continues the execution somehow?

I 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.
I 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.

I 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.

I'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?
