Re: RTF to XML Joaquín M López Muñoz9-Jul-02 13:26 Joaquín M López Muñoz 9-Jul-02 13:26  Hi Alex, I've just downloaded and tried IRun RTF Converter 1.11. It comes with an utility program that seems to work just fine. Also, it provides a .DLL you can use in your apps (not exactly source code, but it's probably the next best thing.) The whole thing is freeware. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: RTF to XML AlexMarbus10-Jul-02 7:41 AlexMarbus 10-Jul-02 7:41  Thanks Joaquín. The main issue is that is really must be platform independent (thus, standard C++). However, I read on the website (http://www.pilotltd.com/irun/) that the sourcecode is available on request. I think I might contact them (unless somebody else knows a better solution?) -- Alex Marbus www.marbus.net But then again, I could be wrong. Calling Access File TommyKnocker9-Jul-02 6:37 TommyKnocker 9-Jul-02 6:37  i want to execute an *.mdb file by my cpp program... does anyone know how to do this??? thanx for all answers... Re: Calling Access File Prem Kumar9-Jul-02 7:34 Prem Kumar 9-Jul-02 7:34  Ok, first of all *.mdb files are not executables! But I think what you want to do is open the mdb file in Access ?? Is that right ? If so you can use ShellExecute(..) ; with lpOperation as "open". SelectObject() Rules Obliterator9-Jul-02 6:32 Obliterator 9-Jul-02 6:32  Hi all, I'm suffering a major resource leak on Win95/98/Me in one of my drawing routines. I realise that before an object is destroyed one must ensure it is not selected in the device context by selecting the old object beforehand. However where my knowledge is lacking is with the use of multiple pens: For example suppose I have a red and a blue pen. Currently I store the old pen when selecting the red. I then use the red pen. Next I select the blue pen, ignoring the returned pen. After using the blue pen, before exiting I reselect the old pen (stored when selecting the red) I then call DestroyObject for both the red and blue pens. Is this sufficient or must I store the oldpen each time and restore it before selecting a new one? Surely not?! This leak is driving me insane! I know the leak is in this function because if I remove the call no crash occurs. However I cannot for the life of me see the leak! I've tried using the example here on CP to Save and Restore the DC state before and after drawing, without success. Thanks -- The Obliterator Re: SelectObject() Rules Prem Kumar9-Jul-02 7:32 Prem Kumar 9-Jul-02 7:32  If you are using MFC, every thing is taken care of if all the objects are local objects. But if you are programming in SDK you need to make calls to DeleteObject with the resource handle. Re: SelectObject() Rules Obliterator9-Jul-02 12:06 Obliterator 9-Jul-02 12:06  I'm using MFC - and all is definitely not taken care of! Anyhow it looks like I've finally found the leak - I'll be testing on Win9x tomorrow to be sure! There was a pen constructed inside an if statement then selected. The old pen should have been reselected before leaving the if statement. As it was not I'm guessing the pen could not be correctly destroyed as its scope was lost. Thanks anyhow. -- The Obliterator Re: SelectObject() Rules Michael Dunn9-Jul-02 19:25 Michael Dunn 9-Jul-02 19:25  Correct, a GDI object that is selected into a DC cannot be destroyed. --Mike-- Just released - RightClick-Encrypt v1.3 - Adds fast & easy file encryption to Explorer My really out-of-date homepage Sonork-100.19012 Acid_Helm Re: SelectObject() Rules Obliterator9-Jul-02 23:14 Obliterator 9-Jul-02 23:14  Wouldn't you have thought it could assert in the destructor if selected in the DC??? -- The Obliterator Re: SelectObject() Rules Anonymous10-Jul-02 11:33 Anonymous 10-Jul-02 11:33  Check your knowledge on DC b4 replying.. Sudip Stupidity Sucks Copy from Screen to Bitmap NickOne9-Jul-02 6:29 NickOne 9-Jul-02 6:29  Hello all, I'd like ot copy from the screen to a bitmap. I have an MDI application that opens DIBs. After I open one, I'd like to get this DIB from the screen as a new bitmap in a new window. I read the VC++ 6.0 Bible and they said just do this void CDisplayDIBView::GetImage(int x, int y, CDC *pDC, CBitmap *pBitmap) { BITMAP bm; pBitmap->GetObject( sizeof(BITMAP), &bm); CDC MemDC; MemDC.CreateCompatibleDC(pDC); CBitmap *pOldBitmap = MemDC.SelectObject(pBitmap); MemDC.BitBlt(0, 0, bm.bmWidth, bm.bmHeight, pDC, x, y, SRCCOPY); MemDC.SelectObject(pOldBitmap); } Well when I do this, I get an error saying the instruction at 0x5f47c360 referenced memory at 0x000000e. The memory could not be "read." How would I go about correcting this, or accomplishing what I want to do?

Re: Copy from Screen to Bitmap Ernest Laurentin9-Jul-02 8:32 Ernest Laurentin 9-Jul-02 8:32  First make sure that your bitmap is not larger than your screen or the offset that you passed (x,y) are not playing against you. Make sure your bitmap object is not null or too small. Maybe you need to call CreateCompatibleBitmap(...) with your bitmap object. Good luck!

Thanks for your answers Re: System tray Joaquín M López Muñoz9-Jul-02 5:41 Joaquín M López Muñoz 9-Jul-02 5:41  If you refer to system tray icons, Chris Maunder's Adding Icons to the System Tray will probably cover all of your needs.

Dialog controls Anonymous9-Jul-02 5:31 Anonymous 9-Jul-02 5:31  Hello How can you make a dialog that doesn't take the control of the application (wait for the answer of DoModal)like the tool windows of psp for example... Re: Dialog controls Joaquín M López Muñoz9-Jul-02 5:38 Joaquín M López Muñoz 9-Jul-02 5:38  These are called modeless dialogs. Search for these words on your documentation. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Dialog controls Anonymous9-Jul-02 5:51 Anonymous 9-Jul-02 5:51  Thank you! Re: Dialog controls Prem Kumar9-Jul-02 5:42 Prem Kumar 9-Jul-02 5:42  Ok, I dont know what 'psp' means, but what i think is you need something like a modeless dialog ?? (Yeah, i know its a crime to even post such awnsers, but that was the only thing i could think of from your post! Need some more Data..)

Filetype icon association Brind_Foin9-Jul-02 5:01 Brind_Foin 9-Jul-02 5:01  Hi everybody! I need help quickly to terminate a program at work. I need to know how can I assign and change file icons in respect with their extension. IE : I want to create a file with *.pof as exension then being able to assign an icon to it programmatically... Thanks for your help! Brind If coding looks like drugs... I should go on therapy... Re: Filetype icon association Joaquín M López Muñoz9-Jul-02 5:17 Joaquín M López Muñoz 9-Jul-02 5:17  Blake V. Miller shows how to Associate File Extension with Shell OPEN command and Application. I guess you can dismiss the program part and reuse the code for setting the icon.
