I got lines written over by other text in a CEdit control
-
I have a CEdit control mapped to a large size text field. When the Read Only box was unchecked, all lines were showing up fine when I scrolled up and down the control. But I have to set the box to Read Only. Once Read Only was checked, when I scrolled up and down using the scrollbar, all text in the edit box was over written by other text. I looked into help but unfortunately was not able to find any information on this problem. Eilzabeth

Sound like an error in Comctl32.dll. Try to get the latest version from MS. (I don't have a link - it can be done with MS's download utility)

Hi, the same phenomenon occurs from time to time in Word. Don't know what causes this problem. Are you using the TRANSPARENT property anywhere in your code??? Regards. Alex
Yes, I have to use TRANSPARENT property to set static labels background while setting background color to the form. Eilzabeth

The only download I saw was for Window95, too old. Can you send me the link? Eilzabeth

Use the download utility - the one with the the little hard drives on it. J. ---------------------------- I got this "baby on board" sign - Now people will stop intentionally ramming our car.
Can not find it. A url would be greatly appreciated. Eilzabeth

Hi, you told me that you are using the TRANSPARENT mode for displaying your data. The TRANSPARENT mode usually hides a given rectangle around a text in a window. This rectangle would usually require a certain space to be displayed - visible or not - on the screen. So if you don't leave enough space for your characters - that is the height of a character in a certain font and the space for the rectangle - you may overlap the rectangle of one line with another. Note: the rectangle i am speaking of is an abstract rectangle which cannot be physically displayed. You can calculate the necessary number of space for a specific character by using the following code:
TEXTMETRIC tm; int cxChar, cyChar; // width and height of a character cxChar = tm.tmAveCharWidth //the average width of a char cyChar = tm.tmHeight + tm.tmExtarnalLeadingThe TEXTMETRIC structure encapsualtes almost all avaiable information of chars. What your code suffers is a lack of external leading that is the space around a character that is needed to display is. For more information on this structure I refer you to the MFC documentation or Charles Petzold's Programming Windows 5th edition. This may look a bit comlicated but in the end its somewhat straightforward:suss: Hope it works Regards. Alex
