Re: CD-RW help EliottA9-Nov-09 4:46 EliottA 9-Nov-09 4:46  You misunderstood me, I have a CD-ROM drive that is not writable, but is readable. I can have your CD with installation files which passes all your checks, but your program will not be able to write to the CD-ROM drive, causing whatever types of errors. Check out the CodeProject forum Guidelines[^] The original soapbox 1.0 is back![^] Re: CD-RW help offroaderdan9-Nov-09 4:52 offroaderdan 9-Nov-09 4:52  Yeah the code i have got should recognise that your CD-ROM drive is only readable and as a result dispay the message saying that you cannot install the software. I haven't fully tested the software so you may be right however the checks seem to be doing the right thing. Re: CD-RW help offroaderdan9-Nov-09 4:56 offroaderdan 9-Nov-09 4:56  All i am really aiming to do is to delete 1 FILE from a CD-RW once the installation is taking place (when button install is pressed) and surely if they have a cd-rom drive when they try and press install when that code is run that would surely crash it (ha ha ha) anybody got any ideas of how to delete password.txt on the CD-RW??? thanks in advanced Dan Re: CD-RW help Luc Pattyn9-Nov-09 5:05 Luc Pattyn 9-Nov-09 5:05  offroaderdan wrote: anybody got any ideas of how to delete password.txt on the CD-RW???

Using your method, you're destroying the installation media. If they have to reinstall the app for any reason, they're screwed. They have to come begging back to you for another CD. Customers will just not bother with that. Forget it. Copy protection is just a pipe dream.

Re: CD-RW help offroaderdan9-Nov-09 5:12 offroaderdan 9-Nov-09 5:12  That is the whole point of the disc! I want it like that, if they need a new disc then they can come back to me, it is like only goining to be sold in the village, it not going to be a WORLD WIDE PROGRAM, its going to be a local one! Re: CD-RW help offroaderdan9-Nov-09 5:17 offroaderdan 9-Nov-09 5:17  Ok then Dave if u made an application which u spent a fair amount of ime on lets say 6 months would u just pput it on a disc and perhaps u were selling the disc for £5. Due to the fact that your basically saying that copy protection is a load of rubbish as soon as one person gets hold of it they'll copy it and distrubute it, and when you try and sell it to people surprisingly enough they've already got it. Im not trying to argue with you but how would you try and stop people from getting your software or do you give it out to people for free? Re: CD-RW help EliottA9-Nov-09 5:33 EliottA 9-Nov-09 5:33  Couldn't someone just copy your CD before running any applications on it? Literally copy, make an ISO, whatever before your application removes the cdkey? Check out the CodeProject forum Guidelines[^] The original soapbox 1.0 is back![^] Re: CD-RW help offroaderdan9-Nov-09 5:39 offroaderdan 9-Nov-09 5:39  Yep theres nothing stopping them from doing that however i would say 90% of people would first run the program before copying it. Does any body not know how to take a file of a cd-rw?!?! No offensive but i joined this site because i tought it gave help? I know there are goining to be porblems with the program but they can worked on!!! All i wanted to knwo was how to delete a file from a CD-RW in vb.net Re: CD-RW help Thomas Krojer9-Nov-09 6:07 Thomas Krojer 9-Nov-09 6:07  Try to delete the file with the windows explorer or a command line! You will see, this ist NOT possible in this way. The only way is to create an ISO image and burn it to CD-RW. But this are basics in computer usage, I thought a developer should know some of the basics. Re: CD-RW help Dave Kreskowiak9-Nov-09 9:13 Dave Kreskowiak 9-Nov-09 9:13  I already told you it cannot be done. Your installer is running off the CD, thereby LOCKING THE DISK FROM CHANGES. You cannot delete a file off the CD because you have to reburn the CD in order to do that, but, since there are open files on the CD (i.e.: your installer), the CD is blocked from being written to.

Re: CD-RW help Dave Kreskowiak9-Nov-09 9:16 Dave Kreskowiak 9-Nov-09 9:16  I have a licensing server setup. My apps gather information from various points in the system, combine it all into a "signature", and send it to my server. My server gives the OK if it's safe to run or not. My apps "phone home" every time they run, so you must have internet access to launch them. No, you're not getting the details on how I do this because, obviously, I don't want those details out in the world.

I have created the setup project with merge modules of crystal report ( as my application also has crystal reporting feature). Now I want to deploy this on another PC, but that PC doesnot have SQL Server installed on it. So do I need to install SQL server on my client PC for this, or any merge modules available for SQL server which can be added while creating the setup project? Please suggest me how to go ahead with this. As time is very short, I need some quick solution, It will be highly appreciated. Thanks R.S.

The SQL Server 2005 installation is entirely seperate and would have to run outside of your apps installer. Are you using the full SQL Server installation of can you use SQL Server 2005 Express instead?

Problem with the EXTFLOODFILL API function Member 42732459-Nov-09 3:59 Member 4273245 9-Nov-09 3:59  Hi everybody, I'm having some problems with this function. The case is the following: I have a picture box control and I put a shape control inside the picturebox, when a I click inside the shape it fills with the color I choosed. Everything is ok until now. The problem is that when I minimize then form and then I maximize it again, the shape is not filled. Somebody has an idea to solve this problem? What am I doing wrong? Thanks in advance. P.D. Excuse my poor english. Re: Problem with the EXTFLOODFILL API function Dave Kreskowiak9-Nov-09 5:03 Dave Kreskowiak 9-Nov-09 5:03  Your not putting all of your painting code in the Paint event of the form or picturebox. Really, you don't even need the picturebox control. Personally, I think MS should remove it from the toolbox. There are a variety of ways of doing this, but I'll just describe one. If you're not painting an image using the entire client area of a form, I'd drop a Panel control on the form and then put all of my code in the Panel controls Paint event. You'll get a Graphics object you use from the event args in the Paint event. Use that to execute all of your painting methods. You don't even need the Win32 API to do this.
