There is a nice article on MSDN that might help. It's at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dncscol/html/csharp03122002.asp[^]

The examples on the page are written in C#, but that's okay because it's all .NET Big Grin | :-D

so will work also in VB.NET.

I hope this helps... Smile | :)

There are Two Options for it

1)Synchronize the client while logging
2)Create DCOM, Run it on server. Create Object on Client
Write a method in DCOM Class to return Date and Time

i m telling u the technique to get the date and time from the Server

Ummm...This doesn't make any sense what-so-ever.
What is the value for?
What kind of file is to be generated?
What directory, where?
What is the 'lib' your looking for supposed to do?
And what's with the comment "DLL entry point generate"?
Are you looking to generate a .DLL file for another app?
What's the app you generating for and what's this generated .DLL supposed to contain?
And to top it all off, are you using VB6 or VB.NET to do this?

Hi! All,

I am creating simplified front-end in VB6/VB.NET, which allows very limited facilities to the user. It allows user to view drawings from different angles(3D Orbit), allows to fill surface with different colors or fill the surface with pictures. User is not suppose to have any other facility than this.

Now, I don't want use COM object application, as it opens another instance of Application which allows user to manipulate drawings in many different ways.

Is there any control (OCX) which allows user to preview drawings? or any other approach?

Suggestion is always welcomed.

Thanking You,

Ritesh.

Hi All,

VB6 CallByName only seems to return a generic Error if one is thrown (ERR.DESCRIPTION : Invalid procedure call or argument). Is there someway of getting my specific custom error messages?

Thanks,

How are you generating your custom errors?

It's been a long time since I did VB6 so I may be wrong on this. But to generate a custom error, I think(!), you had to something like this:

Err.Raise vbObjectError+(your error number), (Source as String - optional), (Description as String - optional)

There are couple of reason for this
1)make sure you connection string that your are passing is correct
My_Connection="Server=<servername>UID=<username>pwd=<password>database=<datrabasename>" i hope this will work out]
2)And if your application is accesing server which is another machine,make sure your netwokr is fine.
write your connection string in this format,which is easy,replace your code with this and build if once again,i hope it will work.

well i think that you had not gone with all the tools which comes with the Visual Studio Package
there is one tool name Package and Deployment Wizard
You can use it
or else you can add the Package and Deployement control
and make your own deployment package
hope this will help you Smile | :)

Hi all,
I have developed an Vb.net application. I have prepared deployment package. But at the Target computer, when I install then it will create a problem related to keycodev2.dll “can not be registered”
Is vb.net framework necessary to install this application at client end. If it is then how can we install silently.
Please help me, I just want to give an single exe file e.g. Setup.exe (it contains exe file of program, .net framework)
Reply me as soon as possible

In order to work your app on client machine , you would require .NET frame work ,that you need to be install seperately.That is available in microsoft site.just go and see in download side of the microsoft.well if you are using any crystal report in the application ,you must include some merge module along with your setup project.
thanxs
ask me if you face any problem
