I am not up to date with the variations of Direct<whatever> but most of it is available to the .NET platform[^]. I imagine there are plenty of articles and tutorials for it.
Also for managed C++ development questions there is a forum titled Managed C++/CLI

I have a little SQL query editor, with a TextBox and a DataGridView, for the query text and the results, respectively. I have these on a SplitContainer. I have no timers, nothing else.
My text in the TextBox keeps disappearing! If I highlight it, it's there, and sometimes when I click in the TextBox, it reappears, but much of the time it remains invisible. Any suggestions as to the cause of this will be most appreciated.

Hi,
maybe something is wrong with your selection colors?
|
|
|
|
|
All standard. Everything else works.
|
|
|
|
|
Is your textbox multiline? This can cause no end of fun if you expect single line behaviour.
Alan.

|
|
|
|
It is multiline, and large. The text literally just becomes invisible!
|
|
|
|
|
This is quite strange. I deleted and recreated the TextBox in question, with exactly the same configuration, and the problem disappeared.
|
|
|
|

See that come from holding your tongue correctly when adding the textbox. Peice of cake.

Hard to say, based on this. Is there a column in common you can use to do a join ? If not, how do you know which 4 goes with which 1 and 2 ? Is 3 a column in common you can join on ?

If you get the SQL right you will have one table with the two lots of data merged.

What you need is a single query:
select drug_name,drug_no, type
from table1 t1 inner join table2 t2 on t2.type_no = t1.type_no
where table1 is the drug_name/number tabler and table2 is the type_no/type table
and then
dim sql as string="{as shown above}"
cmd.connection= con.....
cmd.commandtext= sql
dataAdapter.fill(dataset,"drug")
txdrug_name.databindings.add("text",dataset,"drug.drug_name")
txdrug_no.databindings.add("text",dataset,"drug.drug_no")
txdrug_type.databindings.add("text",dataset,"drug.type")
Its called a table join. I suggest yuo try reading up on sql, otherwise your application is really going to suffer.

I would like to know how to use a progress bar to keep track of video during playback, does anyone know how or can point me to the right direction?
|
|
|
|

I suspect you will run into the infernal problem of the display not updating as your UI thread will be busy running the video, but you could try running a normal progress bar maybe updated by a timer started and stopped from the play/pause/stop events of your video player control.

If your video control has a position property, you can set a timer and set the bar based on that, so it never goes out of sync

Hi All,
I would like to create a module that manages ZOrders of windows in a system so that a particular group of windows (as identified by their Captions or Window Classes) are always together in zorder.
This means no external apps (like notepad or Task Manager) should "interfere" with them. So far the approaches i`ve tried are :
1. Using Windows CBT Hooks to get Activation notifications for all windows in the system. Then based on which windows is being activated i do zorder management
2. Use the SetWinEvent Hook API , so whenever Foreground window changes i do my zorder management. But this is done "after" the foreground change has occured so to bypass it i use AttachThreadInput on the current foreground window, set my app window as the new Foreground window and then detach.
Issue is ZOrder cant be maintained reliably and this sometimes causes my apps to hang.
3. Make all my app windows as Owned Windows of a single Owner window, but with this the internal ZOrder gets messed up if i show/hide my app windows. Is there any extra step i should take internally in my app windows, or issue some Messages form my Owner window before showing/activating any apps ?
4. A general question was : If I give SetWindowPos with the handle of a hidden window, or specify it as the hWndAfter parameter , what effect will this have on the ZOrder ?
All my windows are TopLevel, Non-TopMost windows and they can create their own custom MessageBox and Dialogs (TopMost , Non-Topmost). So whatever mechanism i go with should be extensible to these message boxes too.
Are there any other ways to this task ? Something better or faster ?
I`ll be happy to provide more details if required.
Any help and suggestions are most welcome.
Thanks in advance.

HI,
I am getting the above msg when I try & close a MDI Child form in its form load method, as there is no data to display from SQL, so I catch the error, as below:-
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Sorry there has been an error" );
this.Close();
}
The message appears when it trys to close the form - has anyone any idea's.
The child form is opened from the MDI form as so:-
FrmUserList frmUserList = new FrmUserList(_isLiveConnection);
frmUserList.MdiParent = this;
frmUserList.Show();

I have a collection of business objects bound to a DataGridView, and I would like changes made to my BO's through the grid to be persisted as they happen, or as close as possible to as they happen. I think a per row basis is fine, so which is the best event to handle in which to request that changes are persisted? At the moment I'm using RowValidated, so whenever a row is changed, it persists. Should I continue using this event?

Thanks Mike. I already implement IPropertyChanged, and my grid handles it nicely, but I want the grid to signal an object that a whole object, i.e. row, commit from the UI to the model, is mandated, much like editing records in Access. Until the user moves off a row, the grid should be able to restore the original values for that row.
