I have a 2d array of data that I have performed the sum of the individual column of the 2d array. I want to send the results to a datagridview and also will like to have the result as a 1d or 2d array.
Below is sample of my code
Dim Array1(,) as double
Array1(0, 0) = 5

I am encountering the following issue So i have a device that sends stuff at the serial port, i then parse it and put it into an array of bytes like that:
Dim HCI_Command_Rcvd_Byte() As Byte All good till here What i wanna do is make an array and put this result every time the serial port gives me a new result, for example:
[Code]...
Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)
How set a width for an individual column in DataGridView? I make my datagridview fill. But the problem is The column index 1 is not fit on the datagridview. How can I set an assigned width so that I can managed the spaces.

I have a huge assignment tommorow in which i have to make a trivia game on visual basic. In this game you have to be able to make your own questions (modify/delete etc). Basically I have one form where you can add questions into one listbox and answers into another listbox. Now i have another form with the actual game board. I want to load each individual listbox item from the other form into the array on the game board form. Example. the first item of form2.listbox1 into question(1)
I got this so far

It's a list of computer systems, basically, that the user can purchase.I need to read this file, line-by-line, into an array. Let's call this array csvline().The first line of the text file would stored in csvline(0). Line two would be stored in csvline(1). And so on.(I've started with zero because that's where VB starts its arrays). A drop-down list would then enable the user to select 1, 2 or 3 (or however many lines/systems are stored in the file). Upon selecting a number - say, 1 - csvline(0) would be displayed inside a textbox (textbox1, let's say). If 2 was selected, csvline(1) would be displayed, and so on.
It's not the formatting I need help with, though; that's the easy part. I just need someone to help teach me how to read a CSV file line-by-line, putting each line into a string array - csvlines(count) - then increment count by one so that the next line is read into another slot.So far, I've been able to paste the numbers of each system into an combobox:
Using csvfileparser As New Microsoft.VisualBasic.FileIO.TextFieldParser _
("F:folderprogramnameprogramnameinDebugsystems.csv")
Dim csvalue As String()
[code].....
But this only selects individual values. I need to figure out how selecting one of these numbers in the combobox can trigger textbox1 to be appended with just that line (I can handle the formatting, using the string.format stuff). If I try to do this using csvalue = csvtranslator.ReadLine , I get the following error message:"Error 1 Value of type 'String' cannot be converted to '1-dimensional array of String'."If I then put it as an array, ie: csvalue() = csvtranslator.ReadLine , I then get a different error message:"Error 1 Number of indices is less than the number of dimensions of the indexed array.
I have the following function,
Dim results() As Object = Me.Invoke("webdirect", New Object() {Company, LocationCode, CustomerNumber, OrderNumber, OrderRef, OrderDate, WebLines})
o_Company = CType(results(1),System.Nullable(Of Integer))
o_LocationCode = CType(results(2),String)
o_CustomerNumber = CType(results(3),String)
[Code] .....
So the return type of this function is a string, but I would like to get it back to its original form so I can access the individual sections i.e. o_LocationCode,o_CustomerNumber, etc how can I do that ?
Entire functions looks like this
Public Function webdirect(<System.Xml.Serialization.XmlElementAttribute(IsNullable:=true)> ByVal Company As System.Nullable(Of Integer), <System.Xml.Serialization.XmlElementAttribute(IsNullable:=true)> ByVal LocationCode As String, <System.Xml.Serialization.XmlElementAttribute(IsNullable:=true)> ByVal CustomerNumber As String,
[Code] .....
Called like this
Dim returnArray As String
returnArray = client.webdirect(10, "123", "123", "123", "147", "2011-11-1", webLinesArray, 10, "", "", "", "", "", webRespArray)
No errors on run time but the string seems to be just blank, thats why i was wondering how I convert the string back to the array so I can access the individual elements.
I need to bind a textblock.text property to a single element in an observable collection, or array element, and have the text update using the INotifyPropertyChanged or INotifyCollectionChanged, whichever is best.
Most examples describe ways to bind listboxes or other list views to entire collections, but my application needs to update several textblocks on a screen depending on notification of a change in one or more elements of an array.
textblock1.Text = MyArray(0)...
textblock2.Text = MyArray(1)...
textblock3.Text = MyArray(2)...
textblock4.Text = MyArray(3)...
Is it possible to bind a single textblock to a single array element? Is it possible to get notification of the proper type that will update one or more of the textblocks if any assigned element changes?
I am selecting a distinct user from IT_Cases_List and stored it in an arraystaff(). From this array, I will then call a Stored Procedure to count the no of cases attended by this user,(arraystaff(i)) and loop it until arraystaff.length-1
but the problem is that the count does not tally.
Sub getStaff(ByVal month As String)
If Not con.State = ConnectionState.Closed Then
con.Open()

ok, i've called only once getcases but i'm still having the same problem.
this is what i get when i run the program:
if i get Count(*) from the database, the total no of cases i should be getting is 132, whereas the total of cases i get from the program is 157 (7+7+20+20+49+49+5)
if i run the query from sql, this is what i should be getting
i notice that the Count number gets duplicated (7,7,20,20,49,49,5) instead of (7,20,49,5,10,27,13)

View 14 RepliesI have created a COM Object via VB .NET and exposed some functions that I wish to call in Excel using VBA. I am currently trying to pass an array of objects as a result to VBA but Excel is complaining the following:
'Function or interface marked as restricted, or the function uses an automation type not supported in Visual Basic.'
I have looked around on the internet and have seen similar issues but not to one I am trying to do.My VB .NET function, which I wish to call in Excel is declared as follows:
Public Function CallArray(ByVal serviceName As String, _
ByVal effectiveDate As String,
ByVal serviceParams() As System.Object,
ByRef ArrayRes() As System.Object) As System.Boolean
VBA is complaining about the System.Objects my question is how the heck are you supposed to pass and return arrays from .NET to VBA. Also the data that will be in the ArrayRes() is mixed type, its not just strings etc, its an array of arrays that can contain strings, integers doubles etc.I chose VB .NET because I assumed it would be possible to map to VBA easier.if System. Object and Arrays in VB .NET is not the way, ie maybe theres another way via collections or lists, then Im open to that. I just need to get this data into VBA.Also I could move over to C# if needs be.
I am interested in developing a multi-language program that will have a main .NET GUI but will perform calculations by calling procedures from a Fortran95 dynamic link library file. Right now I am just playing around with a very simple project in order to get the interoperability between the .NET framework and a Fortran95 (*.dll) file working correctly. So far, I've been able to pass the Fortran95 (*.dll) file an array from VB, sum all the elements of the array using an intrinsic Fortran function, and pass the scalar result back to the .NET framework with no problem. However, if I try passing Fortran the exact same array, construct the transpose of that array using another intrinsic Fortran function, and try passing the transposed array back to the .NET framework I keep throwing an exception. I am not a programming wiz, but it appears that when Fortran stores an array in memory, the .NET framework doesn't know how to read that. I am looking for some guidance on how to pass an array from the Fortran95 (*.dll) file back to the .NET framework.
