Unknown Error Causing End Result To Be Incorrect

Mar 15, 2012

I've been programming a game recently and didn't want to make 99 weapons manually. I've tried making a loop do this for me. I've got the loop working, everything is perfect. But when I run the program and list all the Weapon(x).Name [x being any value between 0 & 99] they are all identical... HOWEVER. If I single step through the code it lists all the names from 0 to 99 perfectly fine. Why is it that single stepping through it produces what I want?

Private Sub CreateWeaponList()
Dim StatName(4) As String 'Creating 4 pre-made names for weapons
Dim WeaponName(4), RandomWeaponName As String 'Creating 4 more pre-made names for weapons
For x = 0 To 32
Weapons(x).Type = "Sword"

End Result Of Combobox Selection Keep Showing Same Multiple End Result When There Is Only One Entry?

Dec 10, 2010

I am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

Dim n As Integer
Dim numbers() As Integer
Dim StartFrom As Integer
Dim EndAt As Integer

Make An Array And Put Result Every Time The Serial Port Gives A New Result?

Oct 14, 2009

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)

Limit Result Being Put Into DataSet And Get Next Result From Database

Apr 16, 2010

I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?

For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?

Check The Final Type Of A Variable?

Sep 6, 2010

I have a BaseClass, a DerivedClass1 and a DerivedClass2 from a third party library. DerivedClass1 and DerivedClass2 both inherit from BaseClass.There's a ContainerClass, from the same library, with a member variable ActiveItem, which can be of DerivedClass1 or DerivedClass2, so it is declared as BaseClass.I want to know if ActiveItem is of DerivedClass1, as it can change in runtime without notice.If I do

Dim isDerivedClass1 as boolean = TypeOf(oject.ActiveItem) Is DerivedClass1

then I get a compile time error, telling me that ActiveItem can never be of DerivedClass1 type.I have tried several combinations of GetType and TypeOf but it doesn't seem possible to check this. I have also tried to declare an auxiliary DerivedClass1 variable and comparing their types, but haven't got any luck either.

Edit:The following code doesn't compile in vs2005 SP1.

Public Class Base
Public x As Integer
End Class
Public Class Derived1

Remove Final Comma From String?

Feb 25, 2011

I need to build a comma-delimited string from an array.

For i=0 to ubound(arr)
str+= arr(i) & ","
Next i

The trouble is that I end up with an extra comma at the end.

My current method for removing the comma is:

If str<>"" then
Left(str, Len(str) - 1)
End if

But it seems pretty untidy, and non-generic. I have to do this so often, it's become a pain.

Run A Final Function Vb After Postback Event?

Apr 24, 2012

I have a system that has a gridview on one page with an Update Panel. On selection of one row of a gridview the system posts-back using that CommandName and CommandArgument to post the row that is selected, and then set a Session variable as the ID of that posted selected row. The other controls run Async correctly and the button in question is already registered using this on the RowDataBound event.

Dim gvRowSelect As GridViewRow = e.Row
Dim imbSelect As ImageButton = DirectCast(gvRowSelect.FindControl("imbSelect"), ImageButton)
ScriptManager.GetCurrent(Page).RegisterPostBackControl(imbSelect)

I would like to try and get this session on the button command and somehow within the master page, set a label to the current Session. On the imbSelect command the code is:

Dim cellSnapshot As TableCell = gvSnapshots.Rows(e.CommandArgument).Cells(0)
Session("Snapshot") = cellSnapshot.Text

Within the masterpage is there anyway of calling a function after the Page_Load, and after it has resolved all Postback events?

Add A Final Level Of Nodes To My Treeview From Databases?

Sep 2, 2009

Over the last few weeks i have been trying to add a final level of nodes to my treeview from databases.Within each database is the title of the next node and the key of the node, the child nodes are linked to the parent nodes by the row number/ID column.That is my scenario.

Now comes the next "challenge" At the moment in my code i have had to take out the parts that cycle through each database to add the children as it was causing an error that is described (Learn how to insert hyperlink) here: [URL].. So to overcome that i removed it (dumb approach i know) My justification is that i wanted to see if "my" code worked to add all levels of the nodes. But instead of having All the nodes that should be visible, i only have all the last ones: heres a 'picture to show'What i have below; Whereas all the parents should have children, all the children grandchildren and the grandchildren greatgrandchildren.

Output From Subs Not Appearing Until The Final Sub Has Finished?

May 1, 2010

I'm running three subs in turn (one for each stage of the process that I'm carrying out).The first two of them run a VB Process using:

myProcess.StartInfo.RedirectStandardOutput =
True

[code]....

They then use the StandardOutput of their process to update one TextBox that I'm using for the output of all three stages.The final sub uses the shell because I can't get the EXE that I'm running with it to work properly using a process (this is not necessarily the problem though).The problem is that nothing changes in my textBox until the final sub has finished. The first two sub's output doesn't appear even though this should be just a linear process...
