No Prob - just watch out if the datagrid has NO datasource, then you will get an exception, so you must first check if datsource is NULL i think

Ok, Richard, I did't already. The test for 'Nothing' made no problem. But the comparison of types, I always tried the same sequence like in C#: "...DataType ... Is TypeOf...". That was the error. Thanks again.

There is a little bit of work to do here, but you can do it. You need to use the command line windows installer to un-install the product.
So the command line would be something like
msiexec /x {460FB517-716B-4495-B3CE-44799A75D868}
So if you provide a shortcut to something that will run that command it should unstall your product. NOTE the GUID ({460FB517-716B-4495-B3CE-44799A75D868}) that is above can be found when you click on your setup project and then go to properties. It is the ProductCode. This can change if you put out new versions of your installer.
Anyway, I hope that helps.

How could we possibly guess WHY, while you haven't noticed your code at all?!!

Thanks for your reply. actually i got the solution a bit, but still problem is there. I am using following code to imort the dll.
Private Declare Function MyMethod Lib "C:\Mydll.dll" Alias "MyMethodAlias" (ByRef param As Long) As Long
This is working fine. Now the questions is: Is Alias mandatory?
I have tested with some dll's with out Alias and working fine. And with another dll, giving error with out Alias.
Should we mentions this alias compulsory? Can we give any name for this?
Thanks,
AR Reddy

The Alias part is there if you want to use a different name in your code from what's exported by the .DLL. If, say, the DLL exports a function called "SomeExportedFunction", but you want to use a shorted name in your code, the Declare would be like this:
Private Declare Function MyShortName Lib "Lib.dll" Alias "SomeExportedFunction" ....
If you get the wrong name for the Alias, or if you don't use the alias, your function name doesn't match the exported name in the DLL, you'll get this error.

i am trying to encrypt connection string to protect my passward.
how i do it.

Why do you need to encrypt your connection string. It would be hidden after making its exe.
Ok, waiting for more questions.
|
|
|
|
|
No, it wouldn't. The connection string is being stored in an XML text file.
|
|
|
|
|
Thanks for reply. But is replied as it were in VB.
|
|
|
|

A string in an .EXE is anything but hidden. Let me show you something -> .NET Reflector[^]
