Your connection string is bad. You're trying to use DAO (msdaora.1) which is older than dirt itself. Try http://www.connectionstrings.com[^] for using an Access database.

i m cery new to vb.net i dont knw much abt it.whtever i knw is
if i run this command on server there is no problem

mycon = New OleDbConnection("provider=msdaora.1;user id=scott;data source=;password=tiger;")
mycon.Open()

i think for a standalone sys there should be data source value.if yes
if yes can u tell wht it should be.

my database is in oracle

I just assumed you were using access. Next time, specifiy which database you're using. It makes all the difference in the world how accurate an answer is going to be.

Now, which provider aare you using? If you don't know (you REALLY should!), then use:

Provider=msdaora;Data Source=yourDatabaseName;User Id=username;Password=password;

Crystal Report (Cross Tab Report)

Then how are you going to tell it which database to use?

Are you going to believe the documentation, or some rumor?

Hi,

I have a vb.Net application saved in D:\VbProject\Library.vbproj.
In this folder there exists a bin folder.
I want to get the application path and for that i have used following line of code:
System.AppDomain.CurrentDomain.BaseDirectory.

But this gives me application path as D:\VbProject\bin. In D:\VbProject , I have a folder named DownLoad and i want the path to come as D:\VbProject\Download.

Please Provide me with suitable solution.

Thanks
Siddhi

At design time Application path is actually under bin\debug diretcory. You can use Application.StartupPath statment to address to directory. If there is no directory as named DOWNLOAD, you should consider using Environment.CurrentDirectory + "\Download" (But this is not advisable because current directiroy changes when user deals with saving and opening the documents.)

I hope that helps! WTF | :WTF:

What a curious mind needs to discover knowledge is noting else than a pin-hole.

Make Source Code read only ,, vb.net 2005

24-Mar-07 4:22

The best solution is to copy the Download folder and it's contents to the bin\Debug and bin\Release folders so that your output folders look just like they're going to in the distribution when you install the application on other machines.

Hi...

I will give the source code to others >>
How can I prevent any one from edit the source code of the program >>

Isn't availble on VB.net 2005 ??

Isn't the whole point of Open Source to allow others to modify the your code? You will still have your own copy of the code, right?

I see ..
but I still want to know . can I make the source code is Readonly.. maybe Like pdf files that you can read it only

jooooo

No, you can't. If you give the source code to anyone, you have absolutely no hope of keeping people from making changes to it.

ROTFL. There's NO way you can give someone some files, and make it so they cannot ever edit them. How could that be possible ? You can send the files out as read only. VS 2005 will ask the user if they want to over write the file.

The best you can do is to print it out and give them the code on paper.

C# to VB.NET

Thanks for any guidance.

I am working in a gray area that I am not familiar with.

I have a DLL by a third party supplier. It has a .H file
and a .LIB File. So they have been created in C I am guessing.

How do I wrap this DLL so that I call its functions from
within VB.NET

This is the C# lines from thier example:

#ifdef SPOEM_EXPORTS
#define SPOEM_API __declspec(dllexport)
#else
#define SPOEM_API __declspec(dllimport)
#pragma message("automatic link to spoem.lib") ' <== add this line
#pragma comment(lib, "spoem.lib") ' <== add this line
#endif

Are you sure ? That looks like C to me.

p/invoke is how you'd call your dll in C# or VB.NET.

Thanks for your fast reply:

I have tried:

<dllimport("spoem")> _
Public Shared Function InitParameter(ByVal chSPDir As char)
End Function

<dllimport("spoem")> _
Public Shared Function ExitSpDll()
End Function

<dllimport("spoem")> _
Public Shared Function USBCommunication() As BOOLEAN
End Function

etc.....

It says that it cannot find the DLL. I have Spoem.dll, spoem.h, and spoem.lib in the project
directory. How do I point this class to the DLL.

mlauahi23-Mar-07 6:39

I am using <dllimport("spoem")> _

This line did not appear on the last post

Hello Christain

I cannot add a reference to the DLL, it says that it is invalid.

I have tried both the DLLIMPORT,and then a simpe Declare

It says that it cannot locate the DLL. Where does the DLL need
to reside, and how do I tell my class where it is??

Thanks

You have a dll, or not ? A h and a lib is useless to you in this instance. You'd have to write C++/CLI code that imports those files and exposes a managed class.

If you have a dll, you can't add a reference, that's for COM only.
