I need to build a local .cub file for my Excel-using clients.
I have scrounged together some VB code but it fails :
ConnLocation = "LOCATION=C: est.cub;"
ConnDSN = "SOURCE_DSN=DSN=TEST;UID=test;PWD=pass;"
ConnCreateCube = _
"CREATECUBE=CREATE CUBE [TestCube] (" & _
"DIMENSION [account_code]);"
[Code]...
I have trimmed this down to the above code and am getting a mysterious OLE DB error: OLE DB or ODBC error." when I try to run it.
Attached is a file that creates a 3D cube, I did not make this but found it here at this site.Playing around with it I found out how to, on pressing of any key change the distance of the camera, thus changing the shade of the cube.So if you held a key down it got darker and darker.I want this to happen, but on a timer. So i created a timer, set the interval to 1 and did the same exact code. Set the timer to true, and nothing happens. Ever. I tried doing messagebox.show to show me a message every tick, and that didn't work either. So I went and broke the timer class?
[Code]...
Now i made a new application file, because I use timers all the time and it works. I copy pasted the code, and added the directx stuff, and it ..breaks my timer to do nothing at all ever.. Even if it is unrelated to my cube.
Math.Sqrt is used to find square root but if I want to find cube root or 4 or 5, how I can do?
View 10 RepliesI'm making this rubik's cube program, and I wanted to make a 3d animation of the cube doing the moves, and I figured the best option for that was using the XNA extension. However, doing that brings up a problem. I want to have lots of different options in the Mdi parent form that will interact with the moving 3d cube. The problem with this and using XNA is I can't use both the normal form and the XNA game in the same project. How would I go about having the 2 different projects interact? Just like a txt file or something?
View 1 Replieshow to create a simple controllable 3d cube? I think the code should go in the form.paint area, but i dont know what exactly to put..
View 2 RepliesMuch to my disappointment I recently discovered that VB can not calculate the cube root (or any odd root) of a negative number even though it is a real answer.For instance if you tryMsgBox((-1)^(1/3))You should get -1 because -1*-1*-1 = -1. But no, VB will return NaN, not a number.Anyways, my problem is that I'm making a graph program and the user needs to be allowed to enter any formula they want and have it evaluated so the program can graph it. But if the user enters anything with x^(1/3) or like it, it will fail.So I was wondering if anyone knows of a way around this problem, such as an extension or patch or something that will fix the issue in Visual Basic. I haven't tried VB 2010 but does anyone know if they have they fixed it yet in that version?

I have a search engine that will use a webservice to search through my database to find 3 specific things. I don't even know if it will work like this, but I have a dropdown list on my main page to select Product, Feature, Description. From what the user selects, the webservice should then go to an if statement to use the correct SELECT statement and find results for the search.
Will someone help me figure out how to fix what I've written to make it work? Please don't be too critical, I don't have a lot of experience. I have also been researching SQL Injection because I have a lot of code that is vulnerable so keep that in mind when you look at my code.
I can't get the blue squiggly lines to go away that are underneath the DropdownList1.Value instances on the WebService page.
WebService:
<WebMethod()> _
Public Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer) As String()
Dim Feature As String = DropDownList1.Value
Dim Description As String = DropDownList1.Value
Dim Product As String = DropDownList1.Value
[CODE]..........................
Default.aspx page - Here I need the dropdownlist to tie to the database somehow.

I was looking at making a program which can then build other seperate .exes, is this possible? For example the user types their mail username/password into my program then this builds a seperate one which just connects to their mail with their username/password.

View 4 RepliesI am trying to write simple database application and try to understand ADO.net as well.say I have 2 table
1. table emp with the following field (empId, empName, empPhone, salary, deptId)
2. table dept with the following field (deptId, deptName, deptLocation, deptManager)
emp table is link to dept table via deptId.so I try to build a form with 2 data grids the top will be dept data grid and below it is emp data grid.I try to do this with out using the wizard so I know the flow and understand how to link together step by step.
in the form load section:
dim conn as new system.data.sqlclient.sqlconnection(connectionString)
dim daEmp as system.data.sqlclient.sqldataadapter
dim daDept as system.data.sqlclient.sqldataadapter
[code]....
I am kind of stuck on what to do next, I think the next step is to creat dataview from my understanding before mapping it to the datagrid, but on data grid documentation it say it can only filter datarow, it can't filter data column on the dataview.
I would like to be able to display deptName, deptLocation, no the whole column on the table to data grid, and when user select a record from dept datagrid then the employee info (empname, empphone, empsalary) is display on the second grid (again not the whole emp column table).
the user can update, add or delete emp record from employee data grid by clicing on update button, on update button callback routine I need to put something like.
daEmp.update()
from what my understanding then I need to create update, insert and delete routine and attach it to daEmp so the data grid know how to sync with sql server, so when the user say add new record since the data grid doesn't have all the field display, i.e deptId column is not on data grid, how the table know what the dept id would be? I'd like to learn without the wizard 1st since once I know how everything is link then it is easier to debug since the wizard create lots of file and it's everywhere which make it very hard to understand what is happening for someone new to vb & ado.
Okay Is there a way In vb.net to create an exe from a predefined script, for example rather than writting the methods and subs into the codedom code could I just have a textbox that I could put a script into and then have that built? (obviously omitting button presses and things.)
Im not worrying about ui's at the moment just and exe (hello world style )
Are there any tutorials for this?

I have a VB app that uses a sqlServerCE database. Everything works quite fine on my computer.
When I try to install it on other computers I run into problems. The message "Unable to load the native components of SQL Server Compact corresponding to the ADO.net provider of version 8080"
I am testing on a Win XP virtual machine.
My first attempt was to use InstallShield LE to create the installer. I defined ServerCE as a prerequisite and when I check in add/remove programs it exists, but I still get the error.
Then I tried building the installer with the Microsoft installer. This adds the dll to the program directory automatically, but I still get the error.
I read the KB article referenced (874247) and recompiled the app as an x86 application only, and rebuilding the installer, but have the same problem.
