Oh, sorry I thought you wanted the titlebar one,
ok, then check here:
.NET Framework Class Library
Help.ShowHelp Method
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemWindowsFormsHelpClassShowHelpTopic.asp

thanks for you're help...
Unfortunately I still can't find the answer.
All the examples points to loading a help file or pointing to an index or using the help.showhelp class.
All I want to do is "Emulate" the ? HelpButton on the title bar. Now as soon as I found some reference to that, MS says that this procedure cannnot be used in your code  DOH!
I thought it might be as easy as raising an event like Showhelp.click ...
There has to be a way ¿

VB .NET
I am looking for a way to raise the ShowHelp event for context sensitive help when the user presses a toolbar button.
I want the button to behave exactly the same as the ? on the title bar.
Can anyone help?

Try here,

Unfortunately that does not help...
All examples I have seen and all the searches I've done do not show any examples of raising the HelpButton Event.
The reason I want to do this is I have only one main form and I want to display the minimum and maximum buttons, so I cannot have the HelpButton shown as well. So I am trying to have my own ? HelpButton on a toolbar.
Can't find any answers ...

Hi
Im trying to work with and save large amount of binary data (bytes) but I cannot figure out how to do this in visual basic 6.
In C you can setup a large buffer of bytes, "char buffer[123123]", work in this buffer and then save a part of it with a "fwrite(buffer + 321, 1, 4321)".
In visual basic I can setup a byte array "Dim buffer(1073741824) As Byte" but I cannot get this array as large as I want, about 10Mbytes.
And how can I save only a small part of a byte array fo a file? If I do it Like:
Open "c:\test.raw" For Binary As #FileNumber
Put FreeFile, , bindata
Close FreeFile
Then the whole byte array will be written to the file. I have seen solutions for small amount of bin data where a collection is used and each byte element in the collection is saved in a while next lop with a put in it, but that cannot be that efficient or?
regards Me

can i get the names of enum items at runtime using VB6? 
i.e. does vb6 support some kind of metainformation
(at least a little)?
|
|
|
|
|
No, you can't. VB6 doesn't support Reflection.

Yes it does. Try reading up on the typelib utility and also there is an example on how to make your own typelib utility from the cd. Using that, you can grab the classes, types, or enums defined in a dll or exe.

Great! Didn't know that.

I am using an OLEDBDataAdapter to draw data out of an Access database. I am able to use the fill method and populate a flexgrid control with the data pulled. I need to be able to put this data in a text box though so that i can copy and paste all results in one shot. How do I Pupolate any control that I can pick more that one item with copy and paste action with multiple date. At current the command I am using is OLEDBDataAdapter.fill this is a very simple program. TIA

I need some help, or maybe just a reasonable suggestion to point me in the right direction.
I'm using a RichTextBox to display information in a single user app. I'm adding text to this RTB by way of a TextBox. My issue is this. I can't seem to find a simple way to cause the RTB to display the lastest text that was sent to it, since the text it at the bottom of the RTB. Once I send the new text I need the RTB to scroll to the bottom so the last text is visible. I have tried a API but I not having any luck.
Any suggestions?
Thanks for any help.

Yes it is try this
Public Sub DisText(ByVal text As String) <br />
txtmsgsrv.SelectionColor = ColorRes <br />
' <br />
txtmsgsrv.Focus() <br />
txtmsgsrv.AppendText(text) <br />
txtmsgsrv.Refresh() <br />
txtmsgsrv.Focus() <br />
txtmsgsnd.Focus() <br />
' <br />
txtmsgsrv.SelectionColor = Color.Black <br />
End Sub <br />
Hope this helps u,
Ravi.

It gets simpler:
RTB1.SelectionStart = RTB1.TextLength
RTB1.Focus()
RTB1.ScrollToCaret()

Hi,
I have a table in my Access DB that looks like this:
ID (autonumber)
MyNum1 (number)
MyNum2 (number)
MyStr1 (string)
MyTime (Date/Time)
I've used the Designer to create a typed dataset and a Data Adapter for that table. I added a row to that table and updated the db:
mytable.AddMyDataRow(myrow)
Update( New DataRow() { myrow } )
Because I only want to update that one single row.
I closed my app and re-opened it, and I immediately fill the dataset with the rows from the table, including the one above.
Now, I want to add another row. I do exacly the same thing, and I get an exception when calling Update on the new row:
"Parameter ?_2 has no default value."
The ?_2 changed to ?_1 after I deleted the adapter and re-created it. Dunno why.
I'm really stuck on this. Anyone has an idea what's going on?
Thanks.
