How to make the aplication read data from memory , to create the ISO image. Pls help Thanks.. Vini Re: Reading data from memory Michael Hendrickx4-Oct-04 6:32 Michael Hendrickx 4-Oct-04 6:32  Is the data opened in your application, or is it in another process? If the latter is the answer, then you might get a access denied error, since you are trying to access memory that doesn't belong to you.

To clear the scenario, its like an image editor which can modify an existing image file. The modified data need to be used for ISO image creation for CD burning. The original file remain intact. Is there any control/component to open an image for editing ? pls help Thanks Vini Book on Visual Studio 2003 IDE Vikash Dubey4-Oct-04 1:53 Vikash Dubey 4-Oct-04 1:53  I want to know some good book on the Visual C++ .Net 2003 IDE which explains all the changes and how to use the new features in the IDE.

Re: Changing color of the Edit box Neville Franks4-Oct-04 1:05 Neville Franks 4-Oct-04 1:05  Did you bother to read the page I refered to? You can't use SetBkColor(). You need to return a predefined brush which is used to paint the background.

Problems with the accessing the parallel port using winio wicked_guy4-Oct-04 0:12 wicked_guy 4-Oct-04 0:12  Hi Everone, I am trying to access my parallel port using the library winio.dll. I managed to do so using an administrative account but that wasn't possible using a non-administrative accuont. I have used this function to do so, but unfortunately I couldn't succeed: InstallWinIoDriver("C:\MyApp\Debug\WinIo.sys",FALSE); can anyone halp plz thanx in advance Re: Problems with the accessing the parallel port using winio Max Santos4-Oct-04 0:31 Max Santos 4-Oct-04 0:31  Quote from MSDN if The driver package is not digitally signed then "Manual installation of a driver requires administrator permissions" so , i think you have to be a administrator to install it but you only need to install it the first time, so after installed you can use it without be an administrator I think... auto hiding the parent Poorniselva4-Oct-04 0:11 Poorniselva 4-Oct-04 0:11  hi all, Can any one tell me how to autohide the parent window ??I have an MDI application where when i move my mouse on the child window the parent window should hide....We can these effects in Windows Media player..Can any one tell me how to do it in a normal MFC application..... thanx in advance Re: auto hiding the parent Neville Franks4-Oct-04 0:14 Neville Franks 4-Oct-04 0:14  If you are talking about the parent of an MDI window then hiding it you will also hide the MDI window. You'll have to use your own windows, not MDi for this.
