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.

PInvoke - .net 4 Vs 3.5 ?

Dec 16, 2010

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.

C++ - Pinvoke Using Structs In Call

May 3, 2011

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.

Pinvoke - .NET - Calling Kernel32.DLL's Wow64DisableWow64FsRedirection?

Oct 13, 2010

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?

Enable 'ReaderMode' In .Net Control PInvoke DoReaderMode API

Jun 7, 2011

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?

Using PInvoke To Access Some Routines From A Third Party Library?

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.

VS 2010 PInvoke Stack Imbalance Calling C++ DLL?

Aug 30, 2010

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.

Using Selection.Find In Microsoft.Office.Interop.Word To Find Tracked Changes In A Document?

Apr 15, 2009

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?

VS 2008 Does FIND Always Find Within The FILTER Of A Binding Source

Jun 8, 2009

I've got a form - CMCConsole It pops up a dialog form for adding a new case.If the matter number in a textbox on that dialog form matches an existing cases matter number I would like to find it in the binding source of the CMCConsole form

Private Function CheckMatter(ByVal MtrNum As String) As Boolean
Dim cfIndex As Integer = CMCConsole.caseBS.Find("MatterNumber", MtrNum)
Dim cfIndex2 As Integer = CMCConsole.casefileBS.Find("MatterNumber", MtrNum)

[code]....

But it appear the filter for the CASE we were just on that is set on the binding source is keeping the FIND from seeing other cases.

caseBS.Filter = "CaseId=" & e.Node.Tag.ToString

Do I have to clear the filter in order to find a matter number in some other case??

Find Function Does Not Find Last Occurrence

Dec 12, 2009

I have a rich text box with the following text in it:

word word

I am finding the endings of the word, that is, the string "rd". The following code finds the first occurance, but then fails to find the last occurance, and the variable "indexToText " changes to -1.After the first search, the debugger shows the startLocation at character position 4, so it is not past the second occurance but still will not find it.

indexToText = FrmMain.RichTextBoxPrintCtrl1.Find(searchValue, _
startLocation, eof, RichTextBoxFinds.None)

If I change the text to:

word word word

It then finds the first two occurrences and fails to find the last occurrence.No matter how many words I add, it always fails to find the last occurrence.

Find All IPs On A LAN?

Feb 28, 2007

I've been trying to get the IPs (or computer names) of the computers in the same network as the computer running the program.

I got as far as getting all the IPs of the servers in the network wich ended up in a dead end since its all the computers that i need and not the servers only.

My goal is to get acces to files on all the other computers, i guess a shared folder would do the work and just access it as a regular folder, but for that i need the computer name (wich i can get through his IP)

Basicly, I need to find the ips of all computers in the same network wich is not what i get right now...

Dim localIP() As System.Net.IPAddress = System.Net.Dns.GetHostAddresses(System.Net.Dns.GetHostName)
