I am upgrading a project from VB6 to VB.NET. Unfortunately, I cannot include the DLL or even the name of the DLL that I am using here, I am under a confidentiality agreement. However, I hope I can post enough info here to get this frustrating problem solved.
In VB.net: Code:
So, if I run it as such, it errors out while calling SetParameters saying
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
If I comment out the line m_Parameters.SProperties = New S_Properties(9) {...}, then it does not error out, however the function returns 0, which means it did not actually set the parameters to the device. Trying to ReDim SParameters(9) will also give the hresult error. Doing it with my example above, I put a watch on m_Parameters in both VB6 and VB.net and they look IDENTICAL. All data is the same. Why would I get this ArgumentException in VB.NET and not in VB6 when I am passing in the exact same arguments as in VB6?
I am trying to declare a array within a structure, and it is not working. [code] So I want each league to have a single name and id and 20 players.Is there a way other than writing out dim player1, player2 etc.
Can anyone tell me how I would declare an array for data that will come from textboxes? Every example I find seems to be data that comes from an input box, and the array name would just be strInputbox, for example. However, in my case the user will input data into several textboxes (each named txtBox1, txtBox2, txtBox3, etc.) and I'm not sure how to write this.
I found out that you cannot set the array size for a structure when you are making it, i.e
[Code]...
I have to fix this by making a variable with type made by Structure bullet and then redimming it, i.e
[Code]...
This means for every variable with the bullet type i create i have to redim. Is there a way i can set the size of .mesh with .capacity for every single variable created with the bullet type automatically?
Well... I'd like to ask you a question that makes me crazy...Could I create an array of structure and later delete a value from that?For Example I have a structure called "Examples". I create an array of structure and insert 3 values (whatever). Then, I want to delete the value in the position 2 (which real position is 1 [0, 1, 2]). Could I do that?
I am trying to communicate with an external device and i am trying to send a byte array to the external device via sockets but i am always getting a response the message size is too small so i am not sure what i have done wrong. Between the data type there should be no alignment present and all numbers are represented in little endian format. The char array is not null terminated as mentioned in the protocol specifications.I have to send data based on a struct that embeds 2 other struct. So here's my vb.net code for the struct used to convert to byte array and the sending part.[code]
I'm currently trying to make a vocabulary/flash-card program so I want an array that can store multiple values per item. That way I can shuffle the "cards" (array items) while keeping the word, definition, and part of speech on the same "card". So if I where to access the array I would want to be able to do something like this:
Dim vocabList as VocabArray vocabList(0).Word = "blah" vocabList(0).Definition = "blah" vocabList(1).Definition = "blah"
And then if I where to re-arrange them the properties would remain together but just in a different spot of the array.I can get really close to this using an Item Structure and declaring the variable name with () but the problem is I have to include a number with () and I need to be able to add infinite values to the array, I can't have a set number.Also I would prefer to make it like an ArrayList as it has .Add, .RemoveAt, .Insert etc. In normal Arrays there's no easy way to add, you have to resize and stuff.
Anyways here's close to what I want, but I can't have a set amount and I'd prefer the ArrayList structure so I can just have like Array.Add and then have a Item added onto the end with 3 variables on it. The only thing is that with .Add you usually put something in paranthesis after it to denote the value to add, but if I have 3 possible values then I would have to have parameters for it or something, like .Add(Word, Definition).

I am making a class that has a property that I want to be of type System.Drawing.Size. I don't seem to be able to reference system.drawing from within my class, and therefor can't set my property's data type to Size. Anyone know how I might do this?
I'm trying to sort an array based on a structure but whenever I do this, it basically erases all the data in the entire array.I have verified that the array is populated correctly, it is when using array.sort that everything returns blank.
Public Class frmMain Private strSpark() As String = {"PR214","PR223","PR224","PR246","PR247","PR248","PR324", "PR326","PR444"} Private strBrands As String(,) = { { } } End Class
What is the right way to declare an array Dim lblname As Label() = New Label(get_num_of_children()) {} Dim mealcheck As Integer() = New Integer(get_num_of_children()) {}
Dim proxy As USImportoerServiceTypeClient = DMRUtils.CreateAndConfigureClient() Dim request As New USDeclare_I() request.DeclareCollection = New US_ITypeDeclare() {}
[code]....
This above code do not work, becase the "US_ITypeDeclare() {}" is empty an only contains a new DeclareCollectionStructure
declare a KoeretoejErklaeringStructure to this an set this date value til "DeclareCollectionStructure.DeclareCollectionValidDate" ?
Dim AttributeValuePairs() As Dictionary(Of String, String) = New Dictionary(Of String, String) byt this i mean AttributeValuePairs is a Array of dictionaries
