CImageList

My problem is i can not draw a 24 bit bitmap using a CImageList. The colors get corrupted. This is my code. What am I doing wrong ? Can I use CImageList to draw 24 bit bitmaps because the code below works fine with 16 bit bitmaps.

First create the image list from a 24 bit bitmap
CImageList m_ImageList;
m_ImageList.Create (IDB_BITMAP2,39,2,RGB(255,0,255));

Then draw it in OnPaint method of my class
CPoint pt (0,0);
m_ImageList.Draw(pDC, m_iIndex, pt, ILD_TRANSPARENT);

Thank you very much

I found the code below in the toolbar section of codeproject. Now it works fine.

CBitmap cBitmap;
cBitmap.Attach( LoadImage(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_BITMAP2), IMAGE_BITMAP, 0, 0,
LR_DEFAULTSIZE|LR_CREATEDIBSECTION)
);
CImageList cImageList;
cImageList.Create(39, 42,ILC_COLOR24|ILC_MASK,2, 1);
cImageList.Add(&cBitmap, RGB(255,0,255));

I guess CImageList can not load 24 bit bitmaps itself for some reason.
But when I load the bitmap and then add it to CImageList it worked.
Thank you very much for your time

Is there a way to show a default selection?

When I start the dialog everything is blank until I select something and I would like to show a default in the list.

Thanks for the help.

Select your default item in OnInitDialog (WM_INITDIALOG handler if not in MFC).

Also in MFC you can use DDX to bind dialog class member variables to controls, then the content of controls will be set from these variables on init, and after OK, the variables will be filled with data from controls.

Creating of variables and DDX binding using Class Wizard is easy.

Sync a PC clock to a more accurate clock.

I have a very accurate GPS clock. I have it connected to my computer through the serial port. Is there a way to either have the GPS clock keep updating the time on my PC clock, or when I read the PC clock, have my program read the GPS clocks time instead. Any ideas would be appreciated.

Thanks,
Shane

We are using GPS to synchronize control system PC with ms precision through serial port, so there is a way. I'm sorry I can't help you with details, because the development of this had cost my employer some money Frown | :(

How, hard can it be? Read, the serial port, parse the string for the time, then call SetSystemTime() to set the PC's clock. You may only want to do this once per hour, or once per day, etc.

How to change the attributes of a file?

Hi there,

I want to move a certain hidden/readonly file (namely thumbs.db) from one folder to another in C++. However, this fails, because the "::rename(src, dst)" function does not like hidden/readonly/systems files.

Now, how can I change one file's attributes in Visual C++? In Visual Basic you have the SetAttr() procedure, but I cannot find a similar function in C++?

Regards,

Marco van der Kolk

Anyone here know TAPI 2?

This one should be a TAPI FAQ...

I'm using TAPI 2 in an application. I need to be able to tell the modem not to wait for a dial tone before dialing a number. I could find no such option in the TAPI API, but I found a checkbox in the modem control panel. Is there a way to disable "wait for dial tone" using a C++ program, without the user having to go through the control panel to do this?

Thanks!

Did you try with lineSetCallParams function? because

typedef struct linedialparams_tag {
  DWORD  dwDialPause;
  DWORD  dwDialSpeed;
  DWORD  dwDigitDuration;
  DWORD  dwWaitForDialtone;
} LINEDIALPARAMS, FAR *LPLINEDIALPARAMS;

help with try catch

I need to know how to write a try catch for this. What goes iinto the catch? In the try I will be openeing and reading registry keys. If the keyOpen operations fail I dont want keyClose to be called. Is try-catch the way to organize this, or an if statement?

Thanks,
ns

If you're using bare Win32 API, then you'll get no exception - you'll have to check return values. If you're using one of class wrappers for registry... it depends on class. Read the class documentation to check how error handling works.
