In the Window Procedure, do the following:

<br />
case WM_NCACTIVATE:<br />
  return DefWindowProc(hWnd, message, (WPARAM)0, lParam);<br />
<br />
case WM_CREATE:<br />
SetWindowPos(hWnd, HWND_TOPMOST, 0,0,0,0, SWP_NOACTIVATE | SWP_NOMOVE | SWP_NOSIZE);<br />

Note: the first time the window is displayed, you would need to take away focus from it. after that, it should work as u need.

Thanks for the info!

I tried to use it, but it does not seem to work. Also, when i try and drag the window around, its "jumpy" - like when your CPU utilization is very high and you're trying to move a window...

Any idea about how to fix this problem?

SQL

Does anybody know how to use LIKE correctly. I use "Select * from transaction where myDate LIKE '%1/6/04%'" But it didn`t word. The myDate is a text.

Re: SQL

I think the way you use LIKE is correct but the field type of your myDate might be causing the problem. Is it a VARCHAR or TEXT type? If it is a DATE type, probably this won't work. You need something like this

result.Format(" date '%4d-%02d-%02d' ",d.GetYear(),d.GetMonth(),d.GetDay());

and use = or >= instead.

So your SQL statement should be

SELECT * FROM PO WHERE PO.PURCHASED_DATE = date '1997-12-31'

The example SQL statement above is from PL-SQL of the Oracle but should be compatible on T-SQL and the rest.

Hope this helps

Drawing in a CWnd derived custom control.

Hi!
I'm drawing in a custom control, which derives from CWnd. I placed the custom control inside a dialog, and the custom control is a member variable of the dialog.
When i click on the custom control, i draw a line, from that point to 10 pixels to the right. The problem is that if i drop the line on the right side of the control, a part of the line gets drawn in the dialog.
Is there any way to prevent it drawing in the dialog, or outside the control?
or how do i get the size of the custom control so i can validate if some part ofthe line will be drawn outside the control?

thanks!!

GetClientRect returns the size of the dialog.

Set text of window in another thread?

This has probably been asked before...

Is it possible to set the text of a window (happens to be an edit control) owned by another app (I have a valid target CWnd*)? SetWindowText() and PostMessage() seems to work only if the window is owned by the same thread.

Unfortunately the method fails with error 1159 (The message can be used only with synchronous operations). Too bad there's no SendThreadMessage(). :)

Rebar: Dialog bar

Jorgen E.13-Jun-04 13:06

Hi,

Another one of my newbie problems Big Grin | :-D

, and this time I just don't know where I should start. My MFC-app has a rebar with two bands. One is the "standard" toolbar, which is working fine. The other one uses a small dialog resource, which in turn contains two controls besides a couple of static labels, a checkbox and a combo-box.

The thing is, I need to be able to set and get the values in these controls, and I quite frankly don't have a clue on where to start. I've created a seperate class for the dialog resource, and created a couple of control variables in this class.

Now, I need to be able to set the values for these controls, basically when the window opens (SDI + CScrollView)... I've tried a couple of things, which, well..., didn't work Sigh | :sigh:

Any clues on how to do this?

Another thing is getting the values, I need to do this when drawing my view - the controls defines how the view should be drawn. I can probably do this knowing the answer to my last question, but... how??

I realize that this isn't exactly the hardest questions being asked around here, so thank you for your time and help.

Regards,

Jorgen E.

>> I've created a seperate class for the dialog resource,

Have you worked with MFC CDialog based classes before? Have you used MFC's DDX mechanism to get/set values from a CDialog class?

If not you should consider going through a turtorial like Scribble or something.

Well, I have worked with them, but not enough it seems :P I'll take another look at scribble!

Assuming I didn't confuse you too much with my question, and you understood me: any more ideas? Anything is appreciated!
