if i create the second dialog box in OnInitDialog of the first class,while executing it is showing the second dialog box for a second and in abrupt manner(the dialog box moves from the bottom of the screen to the top leaving traces behind) and then the second dialog disappears.

after that the 1st dialog box is shown normally.

how to display the second dialog box continously?

thanx in advance

As khan++ has told you , you will have to use modeless dialogs for that ,
Here[^] you will find all you need for creating and using modeless dialogs.

hai ,
i guess that you will have to make both the dialogs modeless and GetDlgItem(IDD) will help you to retrieve the handle for the other dialog box in which the IDD is the name you assigned in the resource editor.

I have created a view which need to be printed
by a printer , The base class for the view is
the CScrollView.
How can i print all the data, i also want to
ensure that if data is long enought not to
fit on one page then there should be some
blank space left at the starting and ending
of every page.

GetClientRect

Hi,

I have created a custom window with only WS_POPUP style. That is it does not have border and caption. A special border and caption are drawn in its client area. It is supposed to use a virtual client area, which is less than the actual client area.

In this case the parent or any other window calls myWnd.GetClientRect( &rt ), it will get the actual client area, not the area defined by me. I need to give the virtual client area rather than the actual.

Is there any method to supply the virtual client area to GetClientRect() function call?

Thanks in advance!

You can overload GetClientRect(LPRECT lpRect);
In your implementation, Use ::GetClientRect(hWnd, &rect);
Then rect.DeflateRect(10,10,10,10);
It will make the rect smaller by 10 pixels each side. Change that to taste.

this is this.

Ok it will be fine for CMyWnd::GetClientRect(...).

But what about the call like this...
::GetClientRect( myWnd.GetSafeHwnd(), &rt );
or
myWnd.CWnd::GetClientRect( &rt );

In these case the hWnd is directly used for getting the client rect. I need to manage these types of calls also.

Thank you!

Then don't overload GetClientRect().
Use DeflateRect() with every call, I guess.

this is this.

I'm sorry to say that it is not fine as you think. The custom client area is not a fixed one.
Also I think it is not good to calculate the client area by the caller after the call to GetClinetRect than doing it automatically when the call occurs.

Could you suggest a better method?

Thank you!

The easiest way is to give your window a border, and do the border drawing in the WM_NCPAINT handler. You can adjust the size of the borders and client area using the WM_NCCALCSIZE message.

Import the resource file. It asks for a 'Resouce type'. You can give it any name, like, IDR_MIDI.

Hope that helps.

debug dll with c# main program

Fu Chen25-Sep-05 22:06

25-Sep-05 22:06

I create a dll for a c# program. In main program, c# call this dll by DllImport.
But the dll doesn't work, I try to debug the dll with c# program as command. But to my surprise, the break point in dll is useless. The C# program will run the line to call the dll but never enter into its code. We can watch the output window, and find it load some dlls but not the one to bedebugged.
Does c# program don't load dll which is called by DllImport?
Can anybody tell me how to debug in this situation?

Thank you!

Hi vikas,

You are right, I have used the same example you stated. But when I used my animation file which is littlebit larger in size, it doesn't fits into the given Static Control.

How to move the GIF image at exactly 0,0 postion and show my animation properly.

Thankx advance..
