Re: Converting to Integer Colin Angus Mackay13-Dec-03 9:33 Colin Angus Mackay 13-Dec-03 9:33  Try nLevels = Convert.ToInt32(Levels.Text, 10); I've never tried a TextBox.ToString() but I suspect it won't give you what you want. Also the 16 you've got in your line of code tells it to expect a Hexadecimal value rather than a decimal value. Are you sure that is what you wanted also? --Colin Mackay-- "In the confrontation between the stream and the rock, the stream always wins - not through strength but perseverance." (H.

Also, System.Windows.Forms.TextBox.ToString always returns the Type, "System.Windows.Forms.TextBox", as do most classes (well, their own Type, which is inherited functionality from Object.ToString).   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

This makes absolutely no sense. .NET supports COM (what OLE evolved into) and COM supports .NET through RCW's and CCW's, respectively. There is lots of information about COM Interop in the .NET SDK Framework that you should read because it's not a quick topic to answer - especially in the forums. You can also read more about it from Nick Parker's article, Creating a CCW for COM enabled non .NET applications[^]. For more advanced articles, see mine, Embedding .NET Controls in Java[^], which deals with some of the late- and early-bound issues of CCWs.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Thanks Re: C# control hosed in ActiveX: no tabbing Heath Stewart12-Dec-03 12:01 Heath Stewart 12-Dec-03 12:01  This might actually be better to ask in the COM forum, but basically your C# control (via a CCW) must be UIActive - if memory serves me correctly - to receive the focus. This is specific to the container (which would be a native COM container), not the control itself.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

I do a listView1.BeginUpdate before I start and an EndUpdate when I am done, but even though the contents of the listview are not updating, it still takes an inordinate amount of time to update the object (15 seconds for 2000 items). If the listview is not visible (i.e. the tab the object is on in a tab control is not the selected tab), then it updates in a 10th of the time. I know there is a LockWindowUpdate available as an API call but either I am calling it wrong or it has no effect on the listview object. Can anyone out there help me out? Darryl Borden Principal IT Analyst darryl.borden@elpaso.com Re: ListView BeginUpdate not working Heath Stewart12-Dec-03 11:40 Heath Stewart 12-Dec-03 11:40  This is happening because, while the control is not visible, the Windows handle is not created. When the Windows handle is not created, no sorting (and a few other things) is done. If the control is visible - even if it isn't currently painting items - it sorts with each addition to the Items collection! Even using the LockWindowsUpdate API won't do anything to resolve this issue. The BeginUpdate and EndUpdate methods essentially do the same thing. They disable and enable drawing (respectively) by using the WM_SETREDRAW message. While it isn't documented, LockWindowsUpdate probably does this very same thing. So, you'll either have to bite the bullet and accept the lag, or hide your control and reshow it when you're finished, but that might be annoying to the user. If nothing else, show a progress bar (so add the items in a separate thread, but be sure to use InvokeRequired and Invoke to actually add the items!) while you're adding items to the user knows that something's happening and that they should way. You should also use a try-finally block to show the wait cursor (Cursor.Current = Cursors.WaitCursor) and, in the finally block, set it back to the default (Cursor.Current = Cursors.Default).   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Gary Kirkham A working Program is one that has only unobserved bugs I thought I wanted a career, turns out I just wanted paychecks Re: ComboBox Heath Stewart12-Dec-03 9:35 Heath Stewart 12-Dec-03 9:35  The only way is to P/Invoke SendMessage and send the WM_SETTEXT (msg is 0x000c = 12) to the ComboBox.Handle (Window handle inherited by the Control class). In actuality, though, this is exacly what the Text property does, but at least doing it this way won't raise the TextChanged event and might not do whatever it is you want to avoid.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

My memory is a little frag'd right now! In any case, sending the WM_SETTEXT might work. If not, you could always override the OnPaint event (or, if not available - since most controls in System.Windows.Forms are just wrappers for common controls and some don't allow owner drawing - override WndProc and call OnPaint if the Message.Msg property is 15 (WM_PAINT)).   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?
