I need to come up with a way for a user to select multiple non-consecutive rows of a DataGridView from a touchscreen. Using a mouse & keyboard I would just Ctrl-Click on the rows I want to select, but I dont have that option with a touchscreen.

View 9 RepliesFor my program, I have a webbrowser loaded with a website which contains flash elements. I'm trying to simulate a mouse click (using coordinates) and have the user not need to have the form highlighted (I believe this means the physical position of the cursor shouldn't need be changed either). I've been experimenting with the

This is what I'm looking for however, paired with the ability to simulate the click while not being on that form. I believe this would require the coordinates to be relative to the form itself also. I'm not sure if this is all possible in Visual Basic, however I've seen it utilized in Actionscript and Java.
I have USB device that is detected as human interface device (HID). The device has one button on it. I want to have more of same devices attached to one PC. I would like to simulate a click on that device (it is not a mouse!). It should be simple using Windows API, but I just can't seem to find an example or at least function that does that (I successfully found code that takes position of a MOUSE, and sends click to a MOUSE, but I need that for my HID). What i really need is an example how to simulate click on HID (something like joystick).Second question is a bit more complicated and I can't find a solution. The HID when button is clicked returns data (5-6 bytes). But data returned is immediately printed to the screen (like i typed it on keyboard) and it is followed by CR, however no data is left on clipboard. I don't know how to get that data to my program. Detecting keystrokes using Windows API (something like keylogger), or to make a control (richtextbox) and retrieve data from that control? Thou important notice is that my program is complicated, involves multithreading (cross-thread operations are a mess) and is TIME CRITICAL (as much as it can be on Windows - you get what I mean), so cross-thread access of control will slow me down a lot or even just won't work. Something like this:[code]Even if this problem is solved it still makes it buggy because user should be able to use GUI all the time.

View 1 RepliesI don't know where to start so i will explain my project. I want (someday) to make a macro scripting program kinda like SCAR. The difference will be that it will simulate all the function/procedures from scar. What i mean by simulate is that you can "Mouse Click" without actually moving or affecting the "real" mouse. This will allow you to macro and do what ever you do on the computer at the same time.

I'm about to lose my mind. I'm trying to make a touchscreen overlay for our crappy POS software at work. It is a simple DOS program. I had built an autohotkey script and gui but I just didn't like the look and lack of advanced menus. All I want is to replicate the CONTROLSEND ability of autohotkey. I tried the autohotkey.dll but I have no idea how to add it to my project. I was hoping VB2010 had something built in that can send a string of keystrokes to the DOS program underneath. I have searched all sorts of forum posts for a SIMPLE snippet of code. Seems anyone seeking this is out for nefarious purposes though, and little help is offered. If you worry about this please PM me so I can prove to you my good intentions.
Let me repeat, all I want is a simple snippet of code that when a button is pushed, a specific string (characters and function keys) is sent to a specific out of focus dos box.
I want to show and hide the OSK keyboard (docked at the bottom) for my touch screen application best methods? (I want to make sure when I show that I try to run, in case someone closed it while using the app)
View 6 RepliesI'm developing a GUI for a touchscreen, so when user wants to scroll he/she uses their fingers. Now the thing is that the scrollbar width (with the vertical scrollbar) IS adjustable but the button stays the same height and isn't sufficient for a finger. So the question is : Are the buttons in the scrollbar allso adjustable in size/dimensions.

I am writing a GUI application to run on a touchscreen device using VB.NET and WPF--it must be full screen at all times, like a kiosk app; the window must not be able to resize or move in any way. The window contains a ListBox that users can currently scroll through by dragging across the list. The problem I'm seeing is that when the user drags across the list, the whole window moves a bit, exposing the desktop underneath, then springs back into place once the user stops dragging. I have not been able to figure out how to keep the window stationary while still allowing users to drag across the ListBox to view all list items. Here is a somewhat simplified version of my code:

This isn't really a VB specific question. It's .Net in general... if you have ideas in another .Net language, let me know... I know most of the .Net languages (I don't know that foxtrot or what not weird ones). Furthermore this isn't a 'I don't know the method on some class I should be using' kind of question, it's a design/problem solving kind of question.I'd like to know how you'd approach the problem with in the boundaries set.
View 3 Replieshave a 2d array of structures that holds about 5 or 6 details on each cell. The array size will not be known at compile time so I am using ReDim to resize it. I also have a list (think I have it as an arraylist actually but shouldn't matter really) that I would like to hold a pointer to one of the 2d array elements (as well as some other info). The list is a much smaller subset of the 2d array. The reason I am doing this is that the list needs to be sorted based on some data in the 2d array that will be changing. I don't want to have to search through the list each time to update the values as these lists and arrays can potentially be very large.
Maybe there is a better way to handle this but even if there is I would like to know how to simulate pointers in VB.Net. I know there are IntPtr's and references that I could probably use but I have no idea how to do it with dynamic arrays of structures. I'm familair with pointers from C++ but this is the first time I have tried to use (or simulate since there seems to be no real support for them) in VB.Net.
Not sure how clear that was so here are some snippets of the data types involved and some initialization.
