how to convert a VB6 "User Defined Type" to a VB.Net Structure. I'm lost on the internal array declaration and fixed length strings.Here are my VB6 Type Declarations.
In BTSegment how do I declare fixed length strings in Structure? in BTStatus how do I declare Seg(MAXSEGMENTS) As BTSegment 'Index Segment Structure
I am trying to redirect command line output to a list box in a vba macro, and I've found some code that I think might point me in the right direction, but I keep on getting the same error. When I use this code [code]It gives me the error in the title and highlights the first declaration line.What does it take to define a new "process".
I am having some trouble using Refelction to list the properties of a user defined structure. I need to get a list of the properties and their values.[code]
Following is my code. Private Structure DISPLAY_ELEMENT_TYPE

Actually this is vb6 to .net converted code. I m getting compile error at following line
temp = Lset(DispElem(i)) bcz Lset is not supported in .Net Lset accept string data type for first parameter and interger for second.If you know any alternet solution or if you have any source code for Explicit convert UDT to string type and vice versa.
i want to know how to type cast to user defined type in vb.net.I have a mark object which contains student id , subject name,subject id and mark. I have to read the subject id from a combo box and read corresponding mark value from it to a text box.
I have two structures Public Structure myResearchData

[Code]...
Cleared MyResearchData.arraylistRData for new data to be put in but it also clears the arraylist inside MyResearchDataAList and didn't old the contents of the arraylist
I apologize in advance about asking a newbie question. I am a less-than-intermediate programmer who has done most of his work in VB6, and now trying to wrap my mind around the new concepts of the NET languages.In VB 2010, I have a Structure called "Direction", with one data member -- an integer named "Value". It's supposed to represent a value of degrees from 0 to 359.

when pgm runs and when it reach ".PrinterName = myReader(0)" line, it crashes. Object reference not set to an instance of an object. using immediate window i can see the myReader(0) value. how can i create dynamic array for user-defined type in vb.net?
I am in the process of migrating from VB6 to VB 2008. In a pixel grid system I have thousands of cells with about 15 properties each. In VB6 I employed the user-defined datatype "udtCell()" as my array structure. Is this still a good approach - or should I perhaps make Cell a class?
What I am doing is iterating through all the groups that belong to the top group (Generic reports). Then I take advantage of the GroupPrincipal.GetMembers(True) which will recurse through a given group name. I test to see if the user exits under that group and if true I put the group name in an arraylist.
I use the for each principal in GroupPrincipal.GetMembers to loop through each returned user to see if they exist.
Is there a way to put all the returned users Principal.Name from a given group in GroupPrincipal.GetMembers into an ArrayList? This would allow me to to use Arraylist1.IndexOf to search for user. Which would be much faster then iterating through a returned list using the for each construct.
Sub RetAllMbrs(strUser As String) Dim oPC As PrincipalContext = GetPrincipalContext() '<- this is function somewhere else in the code
I have created a Class Library (dll) with a module and a class in it.The module declares a structure, and an instance of this structure.In the class, there is an arraylist declared.My main program calls a function in the class library class. The class calculates data, stores it in the instanceof structure. Then adds it to the arraylist.When i want to use this data in my main program, i get a Cast void error. Its because The structure of the data in the array if of the structure in Class Library module. Is there a way to change the structure of this array to an identicle structure in the main programs Module. When the function returns the arraylist I have tried storing it in a tmp arraylist and copying, cloning etc the data into another arraylist in my main program. still not working. Do i have to loop through all the data and copy each value to a new instanceofstructure, and store this in the new arraylist?
I was wondering if I can use an ArrayList inside a structure as one of the structure's properties.Or it may be better to replace the structure with a class. If so, can I use an ArrayList as a property of the class.So what I want to do is have the ArrayList as the property of the structure and be able to add items to the ArrayList and clear the ArrayList from a clear method of the structure.
I keep Getting a NullReferenceException Error but I have declared a NEW structure. See below:
Structure ISACReply Public RTD As ArrayList Public SAC As ArrayList Public DRT As ArrayList

When I try to execute the subroutine "calltest" I get a NullReferenceException in the line that says " rv.DRT.Add("HELLO") " even though I have set rv to an instance of ISACReply using NEW.
i am trying to read an existing excel 2007 file from vb.net i used a form with single button and i written code in button click event code is :[code...]
I have a function which iterates through the TextBoxes in my form (and its child controls) and adds each TextBox's name and text to an ArrayList using a structure I called valTxtBox.
Here's a snippet of the VB.NET Public Structure valTxtBox Public nome As String Public texto As String End Structure [Code] .....
Now, the problem is that if I call Clear() for valsTxtBox in the getctrls() function, not all the elements get added to the ArrayList. However, if I don't call Clear() it works just fine. BTW, I'm using VS2008 express which might be relevant.
I have this code working. It sets the Visible property of controlToSecure to False. [Code] However I would like to get rid of hardcoding types of properties. In this case i'm hardcoding Boolean. Instead I would like to define the property type dynamically. I tried it like below but I get an error on line 2 "Type property Type is not defined". I just defined that type on the line before though? Does anyone know why this doesn't work and how i could get it to work? [Code]
Public Pixels(0 To 95, 0 To 127) As Variant Red = Pixels(X, Y) And &HFF i get this code from VB6, and when i transfer to VB05 i got problem said " Operator 'And' is not defined for type 'Color' and type 'Integer'. " i sent to VS2005
Public Pixels(0 To 95, 0 To 127) As Object Dim red As Object Red = Pixels(X, Y) And &HFF
In my application when i click the button i'm getting this" Operator '=' is not defined for type 'Char' and type 'Boolean'." But when i test it locally there is no problem at all!
In trying to add a bit of usage variety to a generic class I'm working on, I ran into this issue with trying to cast an object into an interface instance where the interface is defined inside the generic class.
I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.
