DB/Reporting :: Can't Find PInvoke DLL 'SQLite.Interop.060.DLL'
Jan 19, 2009
I am running Visual Studio 2005 (I tried 2008 and got the same error) using SQLite for a device project. (Windows 6 Mobile)The identical code works perfectly for Windows, but when I execute
f.FileName = PathForDB
SQLconnect.ConnectionString = "Data Source=" & f.FileName & ";"
SQLconnect.Open()
I get the above message. I have tried to "manually" load the DLL at the beginning of my code, but I still get the same message.

i'm Using vb.net 2008 + SQLite I have a Sqlite database with mp3 songs (id3v1 tags) how do i get all genres from songs and add in a array? if several songs have genre "pop". only add "pop" in array once?
What is the most efficient way to do this? Is there a sql statement that does this? Do i have to loop through whole array every time to check if "pop" is there?

I am using SQLite and what I am doing is passing a simple SQL statement to the database, however I want to also return the Unique ID that the insert statement has been entered to, however I am not sure how to do this within a single SQL statement.
My code is below:
Dim mySQL As String = "INSERT INTO DisplaySetFolderTbl (parentID, folderName) VALUES ('" & selNode.Tag & "','" & Trim(Me.txtName.Text) & "')"
Dim cmd As New SQLiteCommand(mySQL, MISData.Instance.dbDRV)
Try
cmd.ExecuteNonQuery()
Catch
Exit Sub
End Try
MISData.Instance.dbDRV is the connection string

I am currently using the code below within a VB.Net application to find specific text in a Word document. The text is surrounded by symbols represented by the character codes in the .Text statement. The code below is working fine. The issue now is that sometimes the desired text within a document has been marked for deletion and appears as tracked change within the document. I would like to find only the desired text that has NOT been marked for deletion. Does anyone know of a way to determine if the found text is a deletion?

I am creating a database project where I take my data from mysql database and then create graphs and charts.I currently have microsoft visual basic 2010 express edition. I am familiar with visual basic but have never used mysql before. I have quried a database into mysql and server connection to the database is working fine. Furthermore I downloaded mysql a week ago so I have the latest connector.I looked at many youtube tutorials and have tried to find mysql.data in the add reference section (in project) but it doesn't seem to be
there.

i have a situation where I need to search a table for a specific record that matches an ID number the user will specify. I know 2 methods to accomplish this. The first would involve writing some VB.net code that would call a TSQL statement and return the value through the return parameter. The second method would involve creating a dataset and populating it with a select statement.

I've an issue regarding p/invoke from managed to unmanaged code. See my original post at the MSDN forum (as brief summary is seen later in this post). Before I go on, I just want to explain a couple of things: I have a wrapper assembly in net 3.5 that does the actual interop to the unmanaged code. Then I have my console "host app" which uses the wrapper assembly. The solution I came up (I refer to my MSDN post) works when the host app is using .net 4, but it doesn't work when changing the host app to use .net 3.5. When changing, I get a AccessViolationException.
host app: 4.0, wrapper assembly: 3.5
-> works
host app: 3.5, wrapper assembly: 3.5 -> throws
AccessViolationException
Do anyone have a clue to why I get an AccessViolationException? Most importantly, how do I get it working with .net 3.5?
Brief summary on the MSDN post I refered to. I have this messy p/Invoke I need to solve. The C declaration looks like this:
long TBAPI TbeAndring (short,
short,
PTB_PU,
PTB_ANDRING_INFO,
PTB_PARAMS,
[CODE]...
Where PTB means that each argument is a struct pointer to an array of arbitrary length. The structs mostly contains strings, doubles, char and short. Anyway, I ended up with this DllImport statement:
<DllImport(NativeLibraryName, CallingConvention:=CallingConvention.StdCall, CharSet:=CharSet.Ansi, SetLastError:=True)>
Public Shared Function TbeAndring(ByVal sAntMoment As Short, _
ByVal sAntPU As Short, _
[CODE]...
As you see some of the arguments are changed by the unmanaged code as well.

So I have this error.
[Code]...
So I'm guessing it has something to do with the fact that I don't have office loaded on my computer. Now I have another laptop, with office that I loaded this project on, and it works fine. So do I have to load office on this computer, or can I just reference something?

I'm really struggling with the following pinvoke call. I've tried numerous different ways of doing this but still no joy. The call runs through, but I get a 'Bad parameter' message back with suggests there is something wrong with the struct, since I've ran through a c++ example of this code and the parameters are all correct.

Have a populated listview with check boxes. If the item is checked I want to send it to report for printing. This code is bypassed:
Code:
Private Sub GetSelectedItems()
If Not Me.ListView1.SelectedItems.Count = 0 Then
[code]....
Count is always = 0. This seems to work only if the item is double clicked. And then only one item is returned in the msgbox. MSDN says "The SelectedItems property will not contain any items if the property is accessed before the ListView handle is created, which typically occurs when ListView is initially loaded for display in the form. You can check to see if the handle is created with the IsHandleCreated property."
When I tried to check for the handle, an error said something about overloading. So I added this:
Code:
Public Overloads ReadOnly Property GetSelectdItems()
Get
If Not Me.ListView1.SelectedItems.Count = 0 Then
[code]....
Which does not help. How to find the items checked/create the needed handle?

Looking at Microsoft's page on Wow64DisableWow64FsRedirection, I see some C code. What if you want to call this function and it's revert from VB.net? So far I have done this:
<Runtime.InteropServices.DllImport("KERNEL32.DLL", EntryPoint:="Wow64DisableWow64FsRedirection")> _
Public Shared Function DisableWow64Redirection() As Boolean
End Function
And I do likewise for the Revert brother function.This seems to work, as the shell command I call after actually finds its exe in system32, but I am not sure about the Revert, does it need a parameter? This Revert page seems to want me to take the output from disable and plug it into the revert call. Does that sound right? How do I change my DLLimport to take in a boolean and actually use it in the Kernal32.DLL function?

I have just upgraded(!) to VS2010, and opened my project from VS2008, which worked, and when i try to run i get a Pinvoke error due to stack imbalance. I am completely lost, on this error. What do i need to do to solve it. The error occurs at the If GetAsyncKeyState(8) Then part of the code below. It is detecting for a backspace being pressed.

I want to enable the 'ReaderMode' for paning/scrolling my control in .Net. Closest thing I found was this Win API function .url....However, I'm not sure how to call this one, in the documentation it says, This function is not declared in any public header. To use it, you must access it as ordinal 383 from Comctl32.dll.I've never called a function that didn't have a name before, can anyone describe how to do this in VB.Net?

I'm using PInvoke to access some routines from a third party library, however i'm getting SEHExceptions when trying to use callbacks defined for one particular method. The callbacks are used to provide feedback from other unmanaged methods within the third party library, passing a string back to the calling application containing a status message.

I've got a dll, written in C++ (which I have the source code for and have compiled it under VS2010)It has a function I want to call in VB
SHARED_FUNCTION int yasdiMasterInitialize(const char * iniFile,DWORD * pDriverNum );
I've declared it as follows:
<DllImport("yasdimaster.dll")> Public Function yasdiMasterInitialize(ByRef IniFile As String, ByRef DriverNum As UInt32) As Integer
End Function
as when I try and use it as follows I get a pInvoke error:
Console.WriteLine("Initialise:" & yasdiMasterInitialize("yasd.ini", Drivers))
From reading around this is something to do with the declaration but I don't know what to change as this is the first time I've tried calling a DLL.

I have a problem listing directory information in a process I wrote to call directory listing of the $MFT routine.The gang has convinced me that the problem is that I'm not calling the routine in Kernel Mode.How does one call a routine in Kernel Mode besides using pinvoke which is slow...."MODERN PROGRAMMING is deficient in elementary ways BECAUSE of problems INTRODUCED by MODERN PROGRAMMING."

I have a SQLite database and I am tyring to query the max value in the RecordID field. This query works when I run it in SQLite but I can not get the VB to return the value, what have I done wrong?
Dim getMaxRecID As String = "SELECT MAX(RecordID) FROM String"
Using cmd1 As New SQLiteCommand(getMaxRecID, pConn)
cmd1.CommandType = CommandType.Text
Dim IDresults As Integer
[code]....
The connection is correctly opening the db, and shows it as open as well. No error, just IDresults returns 0 everytime.

I am writing an app that uses both an SQLite and MySql database. The reason for this before you ask is that it means I can store a local copy of the data onto my user' own machines when they are offline, and then update them to a central server when they are next online.
The problem I have is that when using datasets (on tables created in identical fashion) the itemarray of the mysql database has 9 extra totally blank fields...where as the SQLite itemarray has only the values for the items.
here is a snippet of the code:
CODE:
ultimately I am getting an index size mismatch error but with both tables having the same number of fields this is confusing.
