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; Dave Kreskowiak Microsoft MVP - Visual Basic Re: connectivity in vb.net bhawna_k24-Mar-07 21:25 bhawna_k 24-Mar-07 21:25  i heard frm somwhere data source should be the host string if yes then while opening oracle,there is no need for host string.i leave it blank Re: connectivity in vb.net Dave Kreskowiak26-Mar-07 2:40 Dave Kreskowiak 26-Mar-07 2:40  Then how are you going to tell it which database to use? Are you going to believe the documentation, or some rumor?

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 Siddhi Re: Application Path JUNEYT23-Mar-07 23:47 JUNEYT 23-Mar-07 23:47  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! What a curious mind needs to discover knowledge is noting else than a pin-hole. Re: Application Path Dave Kreskowiak24-Mar-07 4:22 Dave Kreskowiak 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.

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 ?? jooooo Re: Make Source Code read only ,, vb.net 2005 MatrixCoder23-Mar-07 8:33 MatrixCoder 23-Mar-07 8:33  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? Trinity: Neo... nobody has ever done this before. Neo: That's why it's going to work. Re: Make Source Code read only ,, vb.net 2005 kindman_nb23-Mar-07 8:35 kindman_nb 23-Mar-07 8:35  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 Re: Make Source Code read only ,, vb.net 2005 Dave Kreskowiak23-Mar-07 13:51 Dave Kreskowiak 23-Mar-07 13:51  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.

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.

C# to VB.NET mlauahi23-Mar-07 6:25 mlauahi 23-Mar-07 6:25  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 Re: C# to VB.NET Christian Graus23-Mar-07 6:34 Christian Graus 23-Mar-07 6:34  mlauahi wrote: So they have been created in C I am guessing.

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. Re: C# to VB.NET mlauahi23-Mar-07 6:39 mlauahi 23-Mar-07 6:39  I am using <dllimport("spoem")> _ This line did not appear on the last post Re: C# to VB.NET mlauahi23-Mar-07 6:54 mlauahi 23-Mar-07 6:54  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 Re: C# to VB.NET Christian Graus23-Mar-07 7:20 Christian Graus 23-Mar-07 7:20  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.

One of the function calls is SPOEM.USBCommunication(). When I call this is says: Unable to find an entry point named 'USBCommunication' in DLL 'Spoem' ANy suggestions at this point??? Re: C# to VB.NET Christian Graus23-Mar-07 7:46 Christian Graus 23-Mar-07 7:46  Perhaps the DLL is not exporting it properly. But, if it can be called from C++, it would be usable with p/invoke. You should NEVER copy stuff to System32. Just put it in the directory with the exe.

The example code that they give you with this is indeed a C++ 6.0 MFC wizard application. They company supplys the .H, .LIB, and the .dll files. The example just shows those original #DEFINE statements, and there is the exported class for the DLL. I am trying to make the DLL wotk in VB.NET. I am not sure why I am getting an: Unable to find an entry point named 'USBCommunication' in DLL 'Spoem.Dll'. If I am understanding you at this point. I do not use the .H or the .LIB. I should only use the Re: C# to VB.NET Christian Graus23-Mar-07 9:22 Christian Graus 23-Mar-07 9:22  Did you look into how to do pinvoke in VB.NET ? I have no idea, but I'm pretty sure none of your code has tried it, as none has specified the dll name, that I can recall seeing. Here is an example I found online: Public Declare Function BitBlt Lib "gdi32.dll" (hdc As IntPtr , nXDest As Integer, nYDest As integer, nWidth As Integer, nHeight As Integer, hdcSrc As IntPtr, nXSrc As Integer, nYSrc As Integer, dwRop As TernaryRasterOperations) As Boolean Note the Lib "gdi32.dll", that's how to tell VB to load this function from a dll.
