Re: SetBkColor does not seem to work in OnInitDialog Ravi Bhavnani19-Jul-04 6:54 Ravi Bhavnani 19-Jul-04 6:54  SetBkColor() should be used when handling a WM_PAINT message or within a control's DrawItem() override. Use it to set the background color of the DC for the duration of the painting action. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com Re: SetBkColor does not seem to work in OnInitDialog maxsteel19-Jul-04 18:43 maxsteel 19-Jul-04 18:43  even if i use setbkcolor in WM_PAINT is does not do anything. SDI Project - How do display a new Window object that is NOT On Top of the Main Window?? jerry1211a19-Jul-04 4:56 jerry1211a 19-Jul-04 4:56  I have a SDI project where a user using the menu can select and load another window object. I get the new window, but it is on top of my main window. I want to be able to move the window away from the main window. This is the code I use to create and show the window: pStatus->dlg.Create(IDD_FORM_STATUS); pStatus->dlg.ShowWindow(SW_SHOW); Can someone help me out? Thanks.

Deleteing a file si_6919-Jul-04 2:56 si_69 19-Jul-04 2:56  Hi all does ne1 know the easist way of deleting a file i have a txt file which i need to remove in certain situations i tried using remove(str_SettingsPath); but that doesnt work any ideas ?? si Re: Deleteing a file Ravi Bhavnani19-Jul-04 3:04 Ravi Bhavnani 19-Jul-04 3:04  Use unlink(), CFile::Remove() or DeleteFile(). Be sure to specify the file's full pathname. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com Re: Deleteing a file David Crow19-Jul-04 3:17 David Crow 19-Jul-04 3:17  si_69 wrote: i tried using remove(str_SettingsPath); but that doesnt work It should, if used correctly. What value does it return? The file must not have the read-only (and probably the hidden) bit set. You must also have the right privileges.

Then I processed my input files and had it do a system() call for "dir/b > list.txt". Its odd that it created the list.txt in the input files directory . I also checked with getcwd and sure enough it was the input directory. What is the reason for this? Thanks, sb Re: getcwd puzzle Ravi Bhavnani19-Jul-04 2:41 Ravi Bhavnani 19-Jul-04 2:41  Working directories are specific to a drive. You're much better off using an API to get the list of files in a dir instead of calling system(). /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com Re: getcwd puzzle David Crow19-Jul-04 3:12 David Crow 19-Jul-04 3:12  Ravi Bhavnani wrote: ...instead of calling system().

I am just curios to know how you set the output directory because there is no such function as setcwd(), unless you used chdir(). But if you did that then dir /b list.txt will work only on the new directory. On the other hand, "dir /b > C:\...\outputDir\list.txt" will do the trick and probably you knew that already. "dir" command will take as parameters the full path to the input directory and the full path to the output directory. i.e. dir c:\...\inputDir /b > c:\...\outputDir\list.txt Some code posted here would help. But just as the others did, I would recommend API. // Afterall, I realized that even my comment lines have bugs If the sun were to blow up, it would take us 7-8 minutes to realize it.

Thanks Re: How to Hook the Print message bikram singh19-Jul-04 11:04 bikram singh 19-Jul-04 11:04  Try the WH_CALLWNDPROC, WH_CALLWNDPROCRET or the WH_GETMESSAGE hook types. Look for a message id of WM_PRINT. Bikram Singh Re: How to Hook the Print message HemantR...20-Jul-04 21:47 HemantR... 20-Jul-04 21:47  I already use that, but it is not working....

There are some problems though... Whenever a window is hovering the control, the DC does not scroll the contents properly. Example: Custom Control's pos/size: [0,0] - [100, 200] Now imagine a window hovering at [75, 60] - [outbounds control] The DC does not scroll from [75,0] - [100,60] !!! Why? Note: I am calling ScrollDC without passing (nulling) pRgnUpdate and lpRectUpdate (the last two parameters), as I don't really understand their meaning. BOOL ScrollDC( int dx, int dy, LPCRECT lpRectScroll, LPCRECT lpRectClip, CRgn* pRgnUpdate, LPRECT lpRectUpdate ); prob in displaying and deleting text in a view aarti vimal19-Jul-04 1:31 aarti vimal 19-Jul-04 1:31  hi friends, i m working on a radar display in vc++.i.e.i want to plot a trajectory using xyz coordinates.i have to display a number that should move with the trajectory.as i know the xyz co ordinates and the no as well, i m able to display it.but the problem is that as the trajectory moves the no should also move with it.so that the no now gets displayed on the new coordinates and the one that was on the last coordinates gets deleted.so that it also seems to be moving witjh the trajectory. i m displaying the no using textout function.if anyone can give some idea on how to delete the no on the previous points so that it gets erased as soon as we get the new coordinates or if there is some other method of displaying the no so that it is visible only on the current point. waiting for a reply....

Re: prob in displaying and deleting text in a view V.19-Jul-04 2:02 V. 19-Jul-04 2:02  I once did something like this in 2D. I'm not sure if I <i>deleted</i> the textobject, or I drew a rectangle over it. I think it was the second though. Draw a rectangle over your text and draw new text @ new position. good luck!

When the point moves, first overwrite the existing text using a pen whose color is that of the background, then write your new text. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com Re: prob in displaying and deleting text in a view aarti vimal19-Jul-04 22:39 aarti vimal 19-Jul-04 22:39  okay...i understood whatever u said but i suppose my problem is somewhat different.i have something drawn in the background of the view.Whenever i draw a rectangle over the text or overwrite it with the pen, the background also gets erased and if the trajectory is circular the previous path also gets erased.So please if there can be some solution specific to my problem..............

The count you get is the column count.
