Hi Mark,

Thanks for your detailed explanation.

OnCtlColor() is called before the control draws itself so if you draw text there it will be
drawn "under" the control, as you are seeing.

I didn't knew that.... D'Oh! | :doh:

(do you know where can I find a tutorial about the messages and
windows events sequence?)

Mark Salsbery wrote:
You could derive your own picture box class from CStatic and make your m_AtolCorridorBitmap a
variable of that type.
add a WM_PAINT handler to the class. In the OnPaint() implementation, after calling the base
class' OnPaint(), draw your text in the client area of the picture box.

This is just what I'm going to try....
Just one more question:
In design time I can attach a bitmap resource to the picture control.
How can I do it during run time(should I draw the bitmap by myself,or maybe attach
the bitmap in design time and only change the declaration of that control , i.e will it save
the properties I gave it in design time??)

Thanks again,
Eli

You can use the CStatic::SetBitmap() method to set the control's bitmap.

You'll need the bitmap to set, and how you get that depends on where it is.

If it's a resource, the CBitmap class' CBitmap::LoadBitmap() method or the
Image::LoadFromResource() method will do it.

If it's a JPEG, GIF, BMP, or PNG file, you could use CImage::Load().

I wish I had specific links but I don't, sorry Smile | :)

The book "Programming Windows" by Charles
Petzold is a classic text for Windows fundamentals.
The Platform SDK has details on every Windows message. For example, the WM_CTLCOLORxxx messages
state "is sent to the parent window of a button before drawing the button".

Cheers! Smile | :)

You must insert a static control of Toolbox and set bitmap property on the property of control and use of SetBitmap() for insert image file to this control.

Find a library that implements tear-off pages, or tear-off panes and use it. You can also research implementations of tear-off pages/panes, like at: http://www.codeguru.com/cpp/w-d/docking/openfaq/article.php/c7271/[^].

Peace!

Hi All

Infact what kind of activity I need is that...

As in Google Talk there is a Buddy List and if click on any of the buddy name then a Chat Dialog is popped up.
Similar kind of work I need in a Tabbed dialog where a dialog contains a CListCtrl and when any item is clicked then a tab (child dialog) is created now what I want is that when click on a list item then a dialog should be popped up and secondly

As told that in my case in the tab control after clicking on the list item a child dialog is created now I want to give the feature that user can drag and drop the child dialog, and the same time both Tab Control and child dialog should be active...

Please reply that how to proceed for this...better if provide some example..

Thanks & Regards

Similar functionality can be implemented just using non-modal dialogs. When an item is selected you create an instance of your non-modal window. The user will be able to move this window around as necessary.

You can do this by using the custome draw( NM_CUSTOMDRAW ) in listcontrol. Search in the CP for custome drawn list controls.

If you mean full row selection;

DWORD dwExtStyle = m_listCtrl.GetExtendedStyle();
m_listCtrl.SetExtendedStyle(dwExtStyle | LVS_EX_FULLROWSELECT);

SendMessage crashes

Wim Engberts14-Jun-07 1:05

14-Jun-07 1:05

Hi all,

I have a program that does all kinds of graphical stuff. It calls classes from classes, etc. On the deepest level, something may change which requires the mainroutine to redraw the image. Currently, I pass all these classes a pointer to the parent class, and call "m_Parent->SendMessage (XL_REDRAW)". In the main class, I catch this message and perform the necessary drawing actions. However, this causes the program to crash in the release version. Everything goes well in the debug version however.
Please note that the subclasses are no windows in their own right, but are basically just called from the parent class and may in turn again call sub classes themselves.
Anyone any idea why this approach does not work? (and of course most of all: how to solve this)

Thanks in advance
William

If multi threading is involved then remember that SendMessage halts the caller until the message is processed and it returns. In this scenario PostMessage is your friend.
Either way you'd probably be better off doing an Invalidate or InvalidateRect when the message is sent rather than trying to draw directly. This will cause Windows to send you WM_PAINT messages at its convenience which generally works a lot better. If Debug builds work and Release builds don't then it's usually a timing or memory overrun problem. This one looks more like timing/synchronisation but I couldn't be sure wihtout the code Smile | :)

Nothing is exactly what it seems but everything with seems can be unpicked.

   If you are using VS6.0 with MFC, there may be a problem with how your message handlers are written. The version of MFC that ships with 6.0 is very tolerant of mismatched signatures with the message handlers.

   For example, when you create an ON_MESSAGE handler, the function used with it is supposed to have a signature of LRESULT func( WPARAM, LPARAM ), but if you created the function as void func( WPARAM, LPARAM ), it would/may still compile and run correctly in debug, but would crash quickly in release.

   Peace!

run depends.exe to view a list of files on which your application is dependent. From the command prompt you can directly type "depends" to open the dependency walker.

Somethings seem HARD to do, until we know how to do them.

This information is just not enough to get to the root of the problem. Can you provide some more details about your application, what it does, where do you expect the error to be etc etc? Then probably someone here will be able to help you out.

Are you actually trying to start it using the Service Control Manager / the Services applet? A plain-old console app is not a windows service. There are requirements for programs that want to be used a service. http://msdn2.microsoft.com/en-us/library/ms685967.aspx[^]

How you have obtained it ? If it's using dependency walker, you need , all these dlls present on machine, to run the application.

Conditional variable declaration

Hello

I have a custom control which uses GDI+. I have declared a member variable for the custom control. Now, the problem is that GDI+ is supported from Windows XP, and not in Windows 2000. Though GDI+ dll is a redistributable compontent, I dont want to ship it along with our product.

Now, wat I was looking for a solution wherein I first detect the OS on which my Application is running and if its Windows 2000, I dont want to display my custom control which uses GDI+. ie. I was looking as something a conditional variable declaration based on the OS type, because once the variable gets declared it means it wud require GDI+ components and hence my App will not get loaded due the absenceo of GDI+ dll.

Can somebody tell me a why out of this one ??

Thanx.

Why dont ship the GDI+ stuff? It would be nice for your kings (costumers) Cool | :cool:

I do such stuff via a global pointer which has 0 as start value.

CMyCtrl *gpCtrl = 0;

if( IsGdiPlus() )
{
gpCtrl = new CMyCtrl;
}

....

if( gpCtrl )
{
gpCtrl->Show();
}
