OK, sorry to be stupid. I've read a lot of documentation, but I'm missing this.
My main program needs to find an assembly. The assembly will have one class, and it will have known properties and methods within it.
What is not known ahead of time is the name of the class.
My question is how to call the methods within the class. Presumably I need to get the name of the class somehow.
thanks

OK, got it... in case it might help anyone
Dim Asm = System.Reflection.Assembly.LoadFrom "myassembly.dll")
'Since there's only one Exported class
Dim ty As Type = Asm.GetExportedTypes(0)
Dim CSPluginClass As Object = Asm.CreateInstance(ty.FullName, True)
Thanks all!

I assume that this is just your test code, and that you will not ship code that is totally open to SQL injections.
Why are you fetching the data twice? If you need it more than once, fetch into a DataSet or something. Then you don't have to loop through the records to find out how many there are either.
I can't see any code where you try to insert data in any combobox. If you want any help with your error, you have to show the code where it does occur, not some completely different code.

Hi,
I need to get the name of an instance of class. Perhaps, using reflection?
Below i show the example
class Idle<br />
Public one as int32<br />
end class<br />
<br />
class form1<br />
Dim MyIdle as new Idle<br />
public Sub button1_click(sender,...) handles button1.click<br />
textbox1.text= ?¿<br />
end Sub<br />
end class
How can i get the name 'MyIdle' ??

hi!
you can't get the variable name. With Reflection you can get types of assemblies, for example. but a variable name is not metadata in a compiled assembly, because a variable is only a location in the ram.

Hi,
I have a page which has Labels and Textboxes. Those textboxes contain data which is coming from a database. I want to be able to export the data in the textboxes into excel. Is there anyway for doing that? Do you know of any site which shows me how to?
Thanks!

you can use componentOne's tools or either use excel.dll for that.

hi,
if you do not need any formatting in your destination excel file you can create a simple text file with the extension xls. you only have to seperate your content throug vbTab and vbNewLine.

Do you use DataBinding?
Do the number showed in textbox, is allowed to be edited and return to Database?
is String.Format function or Math.Round suitable for u?
|
|
|
|
|
YOU CAN USE FORMAT
Eg:
TXTBOX.TEXT = FORMAT(TXTBOX.TEXT,"####.##")
|
|
|
|
|
Hi,
Or you can just use:
<br />
YourTextBox.Text = Decimal.Round(CDec(YourValue), 2)<br />

My advice is free, and you may get what you paid for.
