• Game Technologies: DirectX, XNA, XACT, etc. How to make a trainer.

  Does anybody on this forum know how to make a video game trainer in c++ (using visual c++ express) I would like to know how to do this. I know it is not impossible. I have searched the internet and all the examples I could find are either extremely old or they are for asm (which I do not know). I am fluent in vb and vb.net, if that matters. If someone would be nice enough to explain the process to me, it would be great. Thank you. I don't like cheating with it, im looking at making a bot by accessing memory and then using these variables to construct a map of variables. Not every one cheats with stuff, just tell him what he wants to kn ...Show All

• Visual Studio Express Editions relate an extension to my application?

  Hi. How can I set windows to open a type of files with my application. like a file.doc will be opened directly by Word. I want that my file.ext will be opened by MyApplication.exe can anybody give me the code to do that... Thanks This is something that needs to be done during installation, and unfortunately it isn't supported by ClickOnce deployment, the only deployment technology supported by Visual Basic Express. If you have the full version of Visual Basic you can specify file associations in the File Types editor for a Setup and Deployment project.

• Game Technologies: DirectX, XNA, XACT, etc. Pic Box with multiple vector objects

  I am trying to create a game where you can set several pieces together on a canvas, draw lines between them, and have the objects passs data. (Much like the pipeline games in cell phones) All I need at the moment is to have 2 bitmaps present on a canvas (pic box panel form, who cares. ) and be able to target them separatly and move them about the screen with drag function, and have a snap point on each image to draw a line between the two. ...Show All

• Visual Studio Team System version control, savepoints and shelving

  I like the idea of 'shelving' in VSTS a lot (we'd use it mainly for personal savepoints). However my understanding is that each shelfset must have a unique name, they cannot be incremental In this case, I would have to create 'john1' then 'john2' etc to get some rollback facility. Not ideal. The alternative approach (that we currently use on SVN) is to have a personal branch for savepoints, commit to that regularly (it's personal, so broken code is fine) and, when finished, merge the work as one unit into the main trunk. If we use this on VSTS would we then be able to totally remove these branches from the server (and reclaim the space). T ...Show All

• Windows Forms inherit control in the flowLayoutPanel.

  Hello.. I want to ask a question because I faced the weird situation. The test process is as below. 1. Make the ancestor form. 2. Put in the flowLayoutPanel and adjust the modifiers to "public". 3. Put in the button in that flowLayoutPanel and adjust the modifiers to "public". 4. Inherit from above the form. ( Make the descendant form ) 5. See the properties of button in the descendant form.     That properties are "read only". If I make the just button and inherit the form, the button's control' properties are modifiable. Why does it happen I can't open my application's windows forms because of that situation since the RTM r ...Show All

• Windows Forms How do I display a PDF file in a VC++ .NET Windows Form application?

  The subject says it all! I have used the Choose Toolbox Items to add the Adobe Acrobat Control for Active X to the ToolBox and then dragged it onto the form. It works, but even though I have the very latest Adobe Acrobat 7.07 Reader Installed, the pdf.ocx control is only version 5.05. I checked in the ActiveX directory of my Adobe\Acrobat 7.0 installation and there was no pdf.ocx there. Also on Adobe's Web site, all their info. on pdf.ocx only mentions the 5.05 version. Is there a better way to display PDF files other than the pdf.ocx ActiveX control I had considered using the native .NET WebBrowser control and relying on the Adob ...Show All

• .NET Development Complete read-only collection wrappers?

  The new generic collection classes sure are nifty but I'm a bit baffled that the feature-rich Generic List only returns a primitive IList as a read-only wrapper (method AsReadOnly). Generic Dictionary, LinkedList and SortedList don't support r/o wrappers in the first place. Come on, guys... aren't there any plans to implement complete r/o wrappers for the final release The non-generic ArrayList has a feature-complete r/o wrapper... why fall back behind this standard with the generic collections No, that's not at all what I'm talking about... a read-only wrapper restricts access to the elements of the c ...Show All
