View 1 RepliesDetecting Victory In Separate Form?
Feb 24, 2009In a project I'm working on, I have 3 separate mazes, a Splash Screen, and a Module for my global variable(gWin, to detect wins on the mazes). When you finish a maze, I'd like to get it so that it does not allow you to go back and redo a maze, to prevent cheating as I want a final screen to appear when they complete all 3 of the mazes. Is there a way that I can make a variable or something to be able to check if a maze was already completed then cause that maze to have it's .Enabled property set to false?

Detecting Items Under A Form - Pattern Matching?
Mar 26, 2009Is there any way to detect the area under a form window. e.g I want to create a grid and use what's in that grid to match patterns.orIs there any way to take a screenshot of the area under a form?
I have been searching all over for something that will do this and the only thing I managed to find was [URL]..I do not however want it for this application (If I really wanted to cheat at a game I would buy the software). But this is a perfect example of the pattern matching I wish to achieve.Edit: OK scratch that... I have managed to take a csreenshot of the region under a form, now has anyone any experience in pattern matching images?
C# - Detecting The Form Move Event From Within A Child Control?
Jul 8, 2010I am creating a user control where when a user clicks a button a popup window will show up with information. The popup window is driven by a toolStripDropDown so when it shows up it does 2 things
Does not move the other controls on the form around but displays over them That it can show the details outside the bounds of the user control itself without having to reserve the space ahead of time
Here is some code
Public Class Popup
Private treeViewHost As ToolStripControlHost
Private Shadows dropDown As ToolStripDropDown
[Code].....
Now my issue is as the form moves or resizes the Tooldropdown does not move relative. I understand that. When I try to capture the move event of the user control that event does not fire when the entire form moves. There has to be something I can capture because the controls in the container of the form move relative, what drives that? I tried wndproc but nothing fires during form move unless the form is repainted.
Credits-style Scrolling Textbox And Form Detecting A Enter Keypress?
Mar 8, 2012I have two issues. The first is that I want to make a textbox scrolling similar to how credits scroll. I don't want it to move on the form, just to scrolling the text down a line/pixel. I thought I could do it with the "Lines" element, but I'm not exactly sure how to execute it.
The other problem is with my flash screen. Right now I have it set so when a button is click, it goes onto the main form. I don't want to use the button but rather have it so if Enter is pressed at any time, it'll go to the main form. All the solutions I've tried to use involve the "e.Keycode" code, but for some reason its unavailable.

View 1 RepliesVS 2008 - Detecting .NET Framework Version
Jan 13, 2010I need to detect if any version of the .NET framework is installed as we are deploying a .NET 2.0 app via logon script (ie XCOPY deployment) to all PCs in our network. The .NET app will be set to start when a user logs in, so we need to determine if .NET 2.0 (or higher) is installed before we deploy the app otherwise the user will get an error each time they log in. Is there any sure fire way to detect .NET via vbscript or batch file? All of the results I have found on google don't seem to be that reliable.
I have recently written a program that detects installed programs in the same way that Add/Remove Programs does but the problem with this is that even Add/Remove Programs does not seem to show the .NET framework on all PCs that have got it installed (like my home PC for example, definitely has .NET 3.5 installed but its not in the Add/Remove Programs list).

View 5 RepliesVS 2008 Detecting Invalid Images?
Jan 12, 2010I have a program that parses INI files (yes yes, I know, but I'm stuck with using them, not my own request), and it downloads external images (if the INI contains the path) to the program and cache's them.
Recently, I've run into a snag with the system. Most of the images use Imageshack for storage, but one of them has suddenly 404'd, and whenever I set it to the picturebox to the downloaded image, I get an out of memory error rather quickly (and the file itself is 1kb).
I guess I need to implement a checking system offline to find out if the image is actually an image or just a '404' text...but is there a way to not have to implement this clientside, and have it be checked when I download it?
