VB6 Control - .NET No Longer Supports DDE
Jan 26, 2010
I know .NET no longer supports DDE however unfortunately most "Finance" related programs (ie, charting and data vendors) use DDE to tie into their data. (Ie, esignal, Marktfeed etc). I've been toying around with NDDE however I'm having a hard time implementing it...unless I'm just making 1 request then it's fine. My question is would it be possible to take VB6 Label Control since it has the "Linkmode, LinkTopic, LinkItem, Label_Change" Properties/Methods and events in it....and create something like DDELabel.dll via Activex control project then use that as part of VB.net?
I tried doing it via the Control Wizard then using it in .NET however I know for a fact I'm not doing it right. Perhaps if someone much more competent could attempt it see if it does give the DDE functionality when used in .NET they can point me in the right direction...

To avoid the TRY Catch Block, is there a way to determine if the control supports the specified event without having a try catch block?

I have run into a small little annoyance while writing a program. I have a bunch of controls on the form and while trying to figure something else out they all got parented to another control, using undo I unparented them from that control however now when the control is clicked the code that is in the sub for them does not run at all. If I double click the control it generated an entirely new sub with a number i.e. what was "Private Sub NumericUpDown1_Value Changed" becomes "Private Sub NumericUpDown1_ValueChanged_1".Near as I can figure the subs with the code are no longer associated with the controls.Is there a quick way of fixing this or am I stuck copy and pasting the code from each sub into a newly generated one?

I have these robots. The maker of the robots (Sankyo) wrote some ActiveX controls. Some work, some don't. There is absolutely no support on the ActiveX from Sankyo or anybody else. I think except for parts and service Sankyo is out of the robotics business in the US.The examples are in VB6. Here is one example of one that does not work:
GetPosition(taskSpec As Long, coordType As Long, posArray As Variant)
Dim vPoints(3) As Single
SRSync.GetPosition 1, 1, vPoints
The error I get is a cryptic hex code that I can't find anything on. If I try the exact code above in VB6 I get a message that says that the vPoints variable is not the right kind of array. I have tried all kinds of data structures in both vb6 and vb.net including just a simple object. I suspect that the data is coming back in some kind of structure that makes vb puke.I have read about marshaling but an still confused. In this case I don't understand the underlying mechanics of how the returned stream of data gets converted into the variable "posArray".I am thinking that if I could just get a look at what is being returned then I could create some kind of code that could chop it up and make it usable.

I have 5 different applications that I have written for my business, they are all interfaces for a point of sale system. I TCP/IP interface handling part of the application is rock solid, problem is that occationally I will come across a small issue, such as a memory leak that I came across a few weeks ago. After I fixed it, I had to then fix said leak in 5 different projects as they all use the same interface base code.Now, if things were different, say a function that all my applications used I would just write it into a class in a dll and have all my applications use the function from that class. Problem is however, using a parent/child explanation unlike my example here where I have interface 1 - 5 as my parents using common.dll as a common child. I need to have InterfaceParent using 5 different children with different attributes.That being said, there are a few stipulations, depending on the customer I may only need to install interface 1 and 3, or 2 and 5, or 1,3 and 4.

how i would check to see if a given class supports the >, = and < operators?
Given an object passed in, I am looking for code that implements the following logic:
If GetType(someObj).SupportsScalarComparisons() Then ...
I don't know if this is a case for Reflection, or ?

I haven't touched a project in about 8 months. It's ongoing for work, but hasn't really been published fully so it gets worked on in my spare time. I went to recompile and the build failed. It had previously worked. I can't figure out why. Part seems to be due to AxOWC11 being recognized, but it shows up in the namespaces. I'm looking for the .dll that shows up as AxOWC11.dll, but I'm not seeing any. I do have one that shows up as AxInterop.OWC11.dll and I do have just a OWC11.dll in my list. I've posted some of the errors below.

I have an application with several forms. The form Main.vb has always been editable in the designer. However, this has changed. The icon in front of the name has changed to a module icon, and the designer and code are no longer found. When I run the application, it still functions as expected.

I am trying to add records from an Access Database into another Access Database using DAO recordset.The VB.NET program would add the records until it hits random stop and error says "Object invalid or no longer set". what would cause this? The recordset contains 7 million records, but it only added approx 6000. Next time i run the program, it would add different number of records again.

I have this:
My.Application.MinimumSplashScreenDisplayTime = 10000
Which I reckon should keep the splashcreen open for 10 secs but it doesn't - infact nothing does. So my question is how do you keep the splashcreen open for longer? The above code is in the splashcreen form loading events and I think that that is the issue but where elses can I put it?

Myself and a colleague have a program called SwiftScreen, its been out for a month now but since May 25th our program is returning an error when they fill out a form that sends us an email (through our application). My best guess is windows recently had an update of somesort but i don't know. Does anyone know a way to send mail, perferably to a gmail account, that still works using Vb.net?
Here is the email code i'm using"
Dim message As System.Net.Mail.MailMessage
Dim smtp As New System.Net.Mail.SmtpClient("smtp.gmail.com")
Dim fromMailAddress As System.Net.Mail.MailAddress

I'm generating a list of names from my database, but I need to validate them so they are no longer than 15 characters.
Dim Name As String
Dim txtFirst = "../../Names/first.txt"
Dim txtLast = "../../Names/last.txt"
[Code]....
I need Name to be no longer than 15 characters, and it doesnt matter if the name stays in tact, it just needs to cut off characters from the end of the string until its 15 or less.

Everything worked great this morning on my ASP project. Suddenly, I have 48 errors. Similar to the following:
Name 'pnlVars' is not declared
'txtPolicyNo' is not a member of 'LetterWriterASP.UW'
Seems every control I reference is now no longer declared or not a member of my project. I checked the page, the controls are all there with the same names & IDs.

My visual studio addin project will not longer build and run in the debugger. I get the following error message when I try to run it:A project with an Output Type of CLass Library cannot be stared directly.It was working about 5 months ago just fine but I opened it and and ran it for the first time since then and get this message. It used to startup another instance of Visual Studio with the addin installed via a proxy addin file. How do I configure the project or solution to make it behave this way again? Do I need to manually tweak the project of solution file?

I have an API that loads into memory from a button click. It can then either load an approx 10MB txt file (ASCII comma delimited characters/decimal list as a string) or live timed data from the internet. The idea is to be able to view the data in a text box. From there I can see what I am doing as far as spitting that info into a datagridview or database. The data is completely out of order in the txt file but has various Getinfo Functions / DLL's accessed via button clicks that split the data into its correct format to display in the text box. The problem I am having is not having fixed length strings in VB 2010. I don't know enough to work out if there is a simple work around or something more complicated required. Everything I have tried has left the textbox empty.
VB 2005 code that works:
Option Strict Off - I want to solve with this ON
Option Explicit On - I want to solve with this ON
Imports VB = Microsoft.VisualBasic
Private Sub Command3_Click(ByVal eventSender As System.Object, ByVal eventArgs As
