• Community Chat IE7 Vulnerability discovered.

  Hi. A vulnerability has been discovered in Internet Explorer, which can be exploited by malicious people to disclose potentially sensitive information. http://secunia.com/Internet_Explorer_Arbitrary_Content_Disclosure_Vulnerability_Test/ What do yo think about this Regards. I think that given the stage that IE7 is in its almost acceptable - why Hear me out - it's in RC, release candidate meaning not the full shbang bug free version - when you are at such stages of developing software, its almost or near perfect but not exactly. Same with Vista and Office 2007, the 2 major upcoming products, there are still a few bugs, even security issues but working towards them. Same thing for your own software, you may have a good few ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. What is a good type of game to start with?

  So when XNA Studio Express comes out I and many other budding(a.k.a. newb) programmers will flock to our PCs to make our own games, but my question is what is the best type, or genre to begin with Would it be a good idea to start 2D, or would jumping into 3D be an option I want to start off with somthing that I can ease into and not get overwhelmed by anything too hard. Thanks for any help you more experienced programmers can give me. Why bring networking into it You can do multiplayer on both platforms.

• Visual Studio Express Editions Transparent BMP

  I would like the user to be able to click on one (or more) colors in a .bmp image, which would cause that color (or those colors) to become transparent in the image. The only transparent .bmp color code I have seen is where the programmer specifies that a certain color in a .bmp image will be transparent, which doesn't help to solve my problem. I am very new at this, and any help will be greatly appreciated.   I think this how image processing people would do it except they wouldn’t do it in VB. It includes a textbox (supplied dynamically) for you to specifiy the percentage latitude. These are typically small values. Three precent will make transparent most of the tiger’s stripes. Since the tig ...Show All

• Software Development for Windows Vista Changes to WMI on Vista that would prevent custom WMI Provider DLL from loading?

  I have a WMI Provider DLL that I devloped a couple of years ago that is used to gather some extra system info and put it in the CIMV2 namespace. It has worked fine on 2000 and XP, but when I try and use it on Vista it doesn't appear to even be loading. MOFCOMP on my MOF file runs OK, as well as regsvr32 with the DLL. I can see the class in the WMI Browser, but no istances of my WMI object. The DLL is based on the C++ framework code generated by the "Microsoft WMI Code Generation Engine" from the WMI SDK released a few years ago. I have tried turning off UAC in Vista but that doesn't seem to make any difference. I haven't been able to find any specific info about why the WMI Provider DLL woudn't work on Vista. Are there any specif ...Show All

• Visual C++ How to launch an App in a ''separate context'' programatically ?

  Hi, I'm having trouble to launch programmatically the process HH.EXE ( with CreateProcess( ) or ShellExecute( ) from another appplication). I 'm having the same error (0, the operating system is out of memory). So, I'm suspecting that the parent process is not able to reserve the necessary amount of memory for its child (HH.exe). Then, I think the only solution is to create the process(HH.exe) in a separate context (because when I use " START--> Run--> Open " to launch HH.exe, everything works well). But Actually, I don't how this can be done. Does anybody know to create a new process, but in a whole new context, separate from parent (programmatically) thanks. I marked the previous post since you ...Show All
