memDC

Hi,

i used the article about the MemDC (http://www.codeproject.com/gdi/bufferdc.asp).

I used the MemDC class and i have also a sideeffect, the background of the view is drawn black.

In the OnInitialUpdate class i put a CLIP_CHILDREN.
At the OnSize-Handler i resize all my controls via MoveWindow(......,FALSE); then i practice a RedrawWindow();

The OnDraw-Handler is modified as it's described. ( i don't have a particulary function which draws the controls explicitely)

Does anyone has an idea?

Does i need to redraw the background in the OnDraw-Handler via CDC *pDC ? But how Sigh | :sigh:

Big thanks Smile | :)

The default of a DC is a monochrome bit map, so that is probably the problem.

Thanks for your reply

The background color is "lighter blue" so it's possible that the blue is replaced with black in monochrome...

What i need to do to change that the DC isn't in monochrome? or that the background is drawn correctly in lighter blue

Big thanks Smile | :)

You can't use in / out in Windows programs. Only drivers are allowed to access hardware at that level. If you search on the web, you'll find various programs that will allow you to write to the parallel port. They've already done the work of writing the driver and provide you with an API to call from a Windows program.

Manually creating modal windows

I was wondering if there's any way to manually create a modal window without the use of the DialogBox function and it's variations. And i'm not talking about manually creating the dialog with DLGTEMPLATE, but rather applying modal properties to an already created window.
Does anybody have an idea about how it could be done?

Just to be sure: you don't use MFC and you work only with the win32 API ?

offcourse.

If you look into the source code of DoModal() function, you can find how MFC is creating a Modal dialog.

It first disables the parent dialogs( if any ),
then shows the new dialog,
runs a messges loop untill the dialog is closed
Enable back the parent dialog,

Hi,

Every thread will have individual handle and ID. Besides everything depends on way how you will want closing your threads.

How to get that individual handle?

when you create thread e.g.

HANDLE hHandle = CreateThead( ... );

CreateThead function returns handle to the only that one thread. Besides the last param of CreateThead returns ID of the thread.

hi,

i am using Windows registry to store an integer value on closing of my dialog and running the application again i am retrieving this value.. this retrieved as string and i tried using "atoi()" to convert but iis giving following error.

"'atoi' : cannot convert parameter 1 from 'CString' to 'const char *'"

and the lines while retrieving the string are..

System::String* valueNames[] = keySoftware->GetValueNames();
for( int i = 0; i < valueNames->Length; i++)
{
CString strValue = static_cast<system::string*>(keySoftware->GetValue(valueNames[i]));
....
....
....

Do this way,
Suppose strKey contains the registry value it read.

int nTemp = atoi (strKey.operator LPCSTR ());

This will surely work.
